Mitsubishi Astron Engine
The Mitsubishi Astron or 4G5/4D5 engine, is a series of straight-four internal combustion engines first built by Mitsubishi Motors in 1972. Engine displacement ranged from 1.8 to 2.6 litres, making it one of the largest four-cylinder engines of its time. Design It employed a hemispherical cylinder head, chain-driven single overhead camshaft (SOHC) and eight valves (two per cylinder). United States passenger car versions had a small secondary intake valve referred to as the "Jet Valve". This valve induced swirl in the intake charge, enabling the use of leaner fuel/air mixtures for lower emissions. It was designed as a cartridge containing the valve spring and seat which simply screwed into a threaded hole in the head, similar to a spark plug but inside the cam cover. The rocker arms for the intake valve were widened on the valve end to accommodate the cartridge, which was equipped with a very soft valve spring in order to avoid wear on the camshaft intake lobe.

Astron (comics)
The Eternals are a fictional race of cosmic beings appearing in American comic books published by Marvel Comics. The following is a list of known Eternals in the Marvel Universe. Characters Earth The following Eternals reside on Earth: * Ikaris''The Eternals'' #1 – A Polar Eternal, son of Virako and Tulayn, father of Icarus. Ikaris' birth name was Daedalus; he adopted the name "Ikaris" after his son, the Icarus of legend, was killed. He became Prime Eternal after challenging Thena. Under the alias of "Sovereign" he introduced the Eternals to the world as a team of super-heroes called the "New Breed." * Ajak – Polar Eternal born to Rakar and Amaa, brother of Arex. With Arex, they were known in Greece as Ajax the Greater and Ajax the Lesser. He disintegrated himself after he discovered he had killed many sets of human twins in ''Eternals: The Herod Factor'' while seeking Donald & Deborah Ritter. * Sersi – Manipulates molecules and atoms. Daughter of Helios and Perse. Ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astron (spacecraft)
Astron was a Soviet space telescope launched on 23 March 1983 at 12:45:06 UTC, using the Proton launcher. Based on the 4MV spacecraft design and operational for six years, Astron was the largest ultraviolet space telescope of its time. The project was headed by Alexandr Boyarchuk. The spacecraft was designed and constructed by the Crimean Astrophysical Observatory and NPO Lavochkin. A group of scientists from these institutions was awarded the USSR State Prize for their work. The payload consisted of an 80 cm ultraviolet telescope, which was jointly designed by the USSR and France, and an X-ray spectroscope. It could take UV spectra 150-350 nm. Placed into an orbit with an apogee of , Astron was capable of making observations outside the Earth's umbra and radiation belt. Among the most important observations made by Astron were those of SN 1987A supernova from March 4 to March 12, 1987, and of Halley's Comet in December 1985, the latter of which enabled a ...

Astron (fusion Reactor)
The Astron is a type of fusion power device pioneered by Nicholas Christofilos and built at the Lawrence Livermore National Laboratory during the 1960s and 70s. Astron used a unique confinement system that avoided several of the problems found in contemporary designs like the stellarator and magnetic mirror. Development was greatly slowed by a series of changes to the design that were made with limited oversight, leading to a review committee being set up to oversee further development. The Astron was unable to meet the performance goals set for it by the committee; funding was cancelled in 1972 and development wound down in 1973. Work on similar designs appears to have demonstrated a theoretical problem in the very design that suggests it could never be used for practical generation. History Strong focusing Christofilos is best known for independently inventing the concept of strong focusing, a feature used in particle accelerators. He had first started work along these lines in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astron (wristwatch)
The Astron wristwatch, formally known as the Seiko Quartz-Astron 35SQ, was the world's first "quartz clock" wristwatch. It is now registered on the List of IEEE Milestones as a key advance in electrical engineering. The Astron was unveiled in Tokyo on December 25, 1969, after ten years of research and development at Suwa Seikosha (currently named Seiko Epson), a manufacturing company of Seiko Group. Within one week 100 gold watches had been sold, at a retail price of 450,000 yen (US$1,250) each (at the time, equivalent to the price of a medium-sized car). Essential elements included a XY-type quartz oscillator of (8192 = 213), a hybrid integrated circuit, and a phase locked ultra-small stepping motor to turn its hands. According to Seiko, Astron was accurate to ±5 seconds per month or one minute per year, and its battery life was 1 year or longer. Anniversaries In March 2010, at the Baselworld watch fair and trade show in Switzerland, Seiko previewed a limited edition ne ...

Shire Calendar
The Shire is a region of J. R. R. Tolkien's fictional Middle-earth, described in ''The Lord of the Rings'' and other works. The Shire is an inland area settled exclusively by hobbits, the Shire-folk, largely sheltered from the goings-on in the rest of Middle-earth. It is in the northwest of the continent, in the region of Eriador and the Kingdom of Arnor. The Shire is the scene of action at the beginning and end of Tolkien's ''The Hobbit'', and of the sequel, ''The Lord of the Rings''. Five of the protagonists in these stories have their homeland in the Shire: Bilbo Baggins (the title character of ''The Hobbit''), and four members of the Fellowship of the Ring: Frodo Baggins, Sam Gamgee, Merry Brandybuck and Pippin Took. The main action in ''The Lord of the Rings'' returns to the Shire near the end of the book, in "The Scouring of the Shire", when the homebound hobbits find the area under the control of Saruman's ruffians, and set things to rights. Tolkien based the Shire's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
