Foundry
A foundry is a factory that produces metal castings. Metals are cast into shapes by melting them into a liquid, pouring the metal into a mold, and removing the mold material after the metal has solidified as it cools. The most common metals processed are aluminum and cast iron. However, other metals, such as bronze, brass, steel, magnesium, and zinc, are also used to produce castings in foundries. In this process, parts of desired shapes and sizes can be formed. Foundries are one of the largest contributors to the manufacturing recycling movement, melting and recasting millions of tons of scrap metal every year to create new durable goods. Moreover, many foundries use sand in their molding process. These foundries often use, recondition, and reuse sand, which is another form of recycling. Process In metalworking, casting involves pouring liquid metal into a mold, which contains a hollow cavity of the desired shape, and then allowing it to cool and solidify. The solidified pa ...

Casting (metalworking)
In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape. The metal is poured into the mold through a hollow channel called a sprue. The metal and mold are then cooled, and the metal part (the ''casting'') is extracted. Casting is most often used for making complex shapes that would be difficult or uneconomical to make by other methods. Casting processes have been known for thousands of years, and have been widely used for sculpture (especially in bronze), jewelry in precious metals, and weapons and tools. Highly engineered castings are found in 90 percent of durable goods, including cars, trucks, aerospace, trains, mining and construction equipment, oil wells, appliances, pipes, hydrants, wind turbines, nuclear plants, medical devices, defense products, toys, and more. Traditional techniques include lost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Tsukuba
is an mountain located at the northern-end of Tsukuba, Japan. It is one of the most famous mountains in Japan, particularly well known for its double peaks, and . Many people climb the so-called "purple mountain" every year for the panoramic view of the Kantō plain from the summit. On clear days the Tōkyō skyline, Lake Kasumigaura and even Mount Fuji are visible from the summit. Japanese mountains are mostly volcanic, but Mount Tsukuba is non-volcanic granite and gabbro in origin. Renowned beautiful granites are produced in the northern quarries even today. Etymology The , a national geography completed in 721 AD, says Mount Tsukuba was named after a noble called . According to this account, the area around Mount Tsukuba was once called . Under the reign of (Emperor Sujin), Tsukuha no Mikoto from the was appointed as its governor. He had a strong desire to leave his name in history, so he renamed the area "Tsukuha", which is now pronounced Tsukuba. History As leg ...

Molding (process)
Molding (American English) or moulding (British and Commonwealth English; see spelling differences) is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or matrix. This itself may have been made using a pattern or model of the final object. A mold or mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material. The liquid hardens or sets inside the mold, adopting its shape. A mold is a counterpart to a cast. The very common bi-valve molding process uses two molds, one for each half of the object. Articulated molds have multiple pieces that come together to form the complete mold, and then disassemble to release the finished casting; they are expensive, but necessary when the casting shape has complex overhangs. Piece-molding uses a number of different molds, each creating a section of a complicated object. This is generally only used for larger a ...

Fire Bell
A fire alarm notification appliance is an active fire protection component of a fire alarm system. A notification appliance may use audible, visible, or other stimuli to alert the occupants of a fire or other emergency condition requiring action. Audible appliances have been in use longer than any other method of notification. Initially, all appliances were either electromechanical horns or electric bells, which would later be replaced by electronic sounders. Most of today's appliances produce sound pressure levels between 45 and 120 decibels at ten feet. Methods of notification The primary function of the notification appliance is to alert persons at risk. Several methods are used and documented in industry specifications published by UL. Alerting methods include: * Sound (audible signals) ** ~3 kHz / ~3100 Hz tone (high frequency). Used in many current notification devices. ** 520 Hz (low frequency). Used in newer notification devices. ** 45 dB to 120&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainwater
Rain is water droplets that have condensed from atmospheric water vapor and then fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mountains, desert climates can exist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Japanese Iron-working Techniques
Early Japanese iron-working techniques are known primarily from archaeological evidence dating to the Asuka period (538–710 CE). Iron was first brought to Japan during the earlier Yayoi period (900 BCE to 248 CE). Iron artifacts of the period include farm implements, arrowheads, and rarely a knife blade. An ironworking industry likely evolved during the late Yayoi or the Kofun period, when iron weapons and armor became more common. However, the best archaeological evidence for early iron-working techniques in Japan dates to the Asuka period, after Buddhism had been introduced to the imperial court of the Yamato state. Japanese bloomeries The traditional Japanese furnace, known as a ''tatara'', was a hybrid type of furnace. It incorporated bellows, like the European blast furnace, but was constructed of clay; these furnaces would be destroyed after the first use. According to existing archeological records, the first tataras were built during the middle part of the sixth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Oldest Companies
This list of the oldest companies in the world includes brands and companies, excluding associations and educational, government, or religious organizations. To be listed, a brand or company name must remain operating, either in whole or in part, since inception. Note however that such claims are often open to question and should be researched further before citing them. Statistics According to a report published by the Bank of Korea in 2008 that looked at 41 countries, there were 5,586 companies older than 200 years. Of these, 3,146 (56%) are in Japan, 837 (15%) in Germany, 222 (4%) in the Netherlands, and 196 (3%) in France. Of the companies with more than 100 years of history, most of them (89%) employ fewer than 300 people. In Japan, very old companies, called '' shinise'', are particularly prestigious.

12th-century Establishments In Japan
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
