Audio-Technica
(stylized as audio-technica) is a Japanese company that designs and manufactures professional microphones, headphones, turntables, phonographic magnetic cartridges, and other audio equipment. Company history Audio-Technica was established in 1962 in Shinjuku, Tokyo, Japan, by Hideo Matsushita as a phonograph cartridge manufacturer. Its first products were the AT-1 and the AT-3 MM stereo phono cartridges. Business rapidly developed and Audio-Technica expanded into other fields. The headquarters and factory moved in 1965 to the current address in Naruse, Machida, Tokyo. In 1969, the company began exporting phono cartridges worldwide and launched the first microcassette recorders. In 1972, Audio-Technica established its US arm in Fairlawn, Ohio, and started shipping VM phono cartridges to European manufacturers. In 1974, the company developed its first headphones, the AT-700 series, launched the same year. The AT-800 series of microphones were introduced in 1978 and in the ...

Microphone
A microphone, colloquially called a mic or mike (), is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers for recording voice, speech recognition, VoIP, and for other purposes such as ultrasonic sensors or knock sensors. Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating diaphragm as a capacitor plate; and the contact microphone, which uses a crystal of piezoelectric material. Microphones typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wireless Microphone
A wireless microphone, or cordless microphone, is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. Also known as a radio microphone, it has a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal from the microphone by radio waves to a nearby receiver unit, which recovers the audio. The other audio equipment is connected to the receiver unit by cable. In one type the transmitter is contained within the handheld microphone body. In another type the transmitter is contained within a separate unit called a "bodypack", usually clipped to the user's belt or concealed under their clothes. The bodypack is connected by wire to a "lavalier microphone" or "lav" (a small microphone clipped to the user's lapel), a headset or earset microphone, or another wired microphone. Most bodypack designs also support a wired instrument connection (e.g., to a guitar). Wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sushi Machine
A sushi machine or sushi robot is a mechanical device that automatically creates various styles of sushi. Several are electrically powered. Some sushi machines produce mounds of sushi rice for creating nigiri. This style of sushi machine may use a hopper that is filled with sushi rice, from where the rice is fed into the machine and the sushi rice mounds are formed and then ejected. After the rice mounds are ejected, sashimi and other ingredients are then manually placed atop them. Some sushi machines can produce sushi rolls, whereby the machine automatically flattens rice into sheets, adds various ingredients such as sashimi, nori (edible seaweed) and vegetables, rolls them up and then slices the rolls into separate pieces. Some roll machines are adjustable to change settings for roll length and thickness. Sushi restaurants and food service operations may use sushi machines to reduce labor costs. Sushi prepared with electric sushi machines may be priced lower at retail stores and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leeds
Leeds () is a city and the administrative centre of the City of Leeds district in West Yorkshire, England. It is built around the River Aire and is in the eastern foothills of the Pennines. It is also the third-largest settlement (by population) in England, after London and Birmingham. The city was a small manorial borough in the 13th century and a market town in the 16th century. It expanded by becoming a major production centre, including of carbonated water where it was invented in the 1760s, and trading centre (mainly with wool) for the 17th and 18th centuries. It was a major mill town during the Industrial Revolution. It was also known for its flax industry, iron foundries, engineering and printing, as well as shopping, with several surviving Victorian era arcades, such as Kirkgate Market. City status was awarded in 1893, a populous urban centre formed in the following century which absorbed surrounding villages and overtook the nearby York population. It is ...

Nigiri
is a Japanese dish of prepared , usually with some sugar and salt, accompanied by a variety of , such as seafood, often raw, and vegetables. Styles of sushi and its presentation vary widely, but the one key ingredient is "sushi rice," also referred to as , or . The inventor of modern sushi is believed to be Hanaya Yohei, who invented nigiri-zushi, a type of sushi most known today, in which seafood is placed on hand-pressed vinegared rice, around 1824 in the Edo period (1603–1867). It was the fast food of the ''chōnin'' class in the Edo period. Sushi is traditionally made with medium-grain white rice, though it can be prepared with brown rice or short-grain rice. It is very often prepared with seafood, such as squid, eel, yellowtail, salmon, tuna or imitation crab meat. Many types of sushi are vegetarian. It is often served with , wasabi, and soy sauce. Daikon radish or are popular garnishes for the dish. Sushi is sometimes confused with sashimi, a similar dish in J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RCA Connector
The RCA connector is a type of electrical connector commonly used to carry audio and video signals. The name ''RCA'' derives from the company Radio Corporation of America, which introduced the design in the 1930s. The connectors male plug and female jack are called RCA plug and RCA jack. It is also called RCA phono connector or phono connector. The word ''phono'' in ''phono connector'' is an abbreviation of the word '' phonograph'', because this connector was originally created to allow the connection of a phonograph turntable to a radio receiver. RCA jacks are often used in phono inputs, a set of input jacks usually located on the rear panel of a preamp, mixer or amplifier, especially on early radio sets, to which a phonograph or turntable is attached. History By no later than 1937, RCA introduced this design as an internal connector in their radio- phonograph floor consoles. The amplifier chassis had female connectors which accepted male cables from the radio chass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continuous Casting
Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots. Since then, "continuous casting" has evolved to achieve improved yield, quality, productivity and cost efficiency. It allows lower-cost production of metal sections with better quality, due to the inherently lower costs of continuous, standardised production of a product, as well as providing increased control over the process through automation. This process is used most frequently to cast steel (in terms of tonnage cast). Aluminium and copper are also continuously cast. Sir Henry Bessemer, of Bessemer converter fame, received a patent in 1857 for casting metal between two counter-rotating rollers. The basic outline of this system has recently been implemented today in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Private Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microcassette
The Microcassette (often written generically as microcassette) is an audio storage medium, introduced by Olympus in 1969. It has the same width of magnetic tape as the Compact Cassette but in a cassette roughly one quarter the size. By using thinner tape and half or a quarter the tape speed, microcassettes can offer comparable recording time to the compact cassette but in a smaller package. History Microcassettes have mostly been used for recording voice. In particular, they are commonly used in dictation machines and answering machines. Microcassettes have also been used in computer data storage and to record music. For the latter purpose, devices for recording in stereo were produced in 1982 and, for higher fidelity, microcassettes using Type IV ("metal", i.e. coated with pure metal particles rather than oxide) tape were sold. This was an attempt by Olympus to cash in on the burgeoning Walkman market; one model, the Olympus SR-11, had a built-in radio and offered a stere ...
