Titanium disilicide. Titanium disilicide (TiSi2) is an inorganic chemical compound of titanium and silicon.

Preparation 
Titanium disilicide can be obtained from the reaction between titanium or titanium hydride with silicon.

Ti + 2 Si → TiSi2
It is also possible to prepare it aluminothermically by the ignition of aluminium powder, sulfur, silicon dioxide, and titanium dioxide or potassium hexafluorotitanate, K2TiF6, by electrolysis of a melt of potassium hexafluorotitanate and titanium dioxide, or by reaction of titanium with silicon tetrachloride.

Another method is the reaction of titanium tetrachloride with silane, dichlorosilane or silicon.

TiCl4 + 2 SiH4 → TiSi2 + 4 HCl + 2 H2
TiCl4 + 2 SiH2Cl2 + 2 H2 → TiSi2 + 8 HCl
TiCl4 + 3 Si → TiSi2 + SiCl4

Uses 
Titanium silicide is used in the semiconductor industry. It is typically grown by means of salicide technology over silicon and polysilicon lines to reduce the sheet resistance of local transistors connections.
In the microelectronic industry it is typically used in the C54 phase.

Titanium(III) phosphide. Titanium(III) phosphide (TiP) is an inorganic chemical compound of titanium and phosphorus. Normally encountered as a grey powder, it is  a metallic conductor with a high melting point.  It is not attacked by common acids  or water. Its physical properties stand in contrast to the group 1 and group 2 phosphides that contain the P3− anion (such as Na3P), which are not metallic and are readily hydrolysed. Titanium phosphide is classified as a "metal-rich phosphide", where extra valence electrons from the metal are delocalised.

Titanium phosphide can be prepared by the reaction of TiCl4 and PH3.

There are other titanium phosphide phases, including Ti3P, Ti2P, Ti7P4, Ti5P3, and Ti4P3.

Titanium phosphide should not be confused with titanium phosphate or titanium isopropoxide, both of which are sometimes known by the acronym TIP.

Noryl. The NORYL family of modified resins consists of amorphous blends of polyphenylene oxides (PPO) or polyphenylene ether (PPE) resins with polystyrene. They combine the inherent benefits of PPE resin (affordable high heat resistance, good electrical insulation properties, excellent hydrolytic stability and the ability to use non-halogen fire retardant packages), with excellent dimensional stability, good processability and low density.  

They were originally developed in 1966 by General Electric Plastics (now owned by SABIC). NORYL is a registered trademark of SABIC Innovative Plastics IP B.V. 

NORYL resins are a rare example of a homogeneous mixture of two polymers. Most polymers are incompatible with one another, so tend to produce separate phases when mixed. The two polymers compatibility in NORYL resins is due to the presence of a benzene ring in the repeat units of both chains.

Properties 
The addition of polystyrene to PPE increases the glass transition temperature above 100 °C, owing to the high Tg of PPE,  so NORYL resin is stable in boiling water. The precise value of the transition depends on the exact composition of the grade used. There is a smooth linear relation between weight content of polystyrene and the Tg of the blend. Due to its good electrical resistance, it is widely used in switch boxes. However, product design is important in maximising the strength of the product, especially in eliminating sharp corners and other stress concentrations. Injection molding must ensure that moldings are stress-free.

Like most other amorphous thermoplastics, Noryl is sensitive to environmental stress cracking when in contact with many organic liquids. Compounds such as gasoline, kerosene, and methylene chloride may initiate brittle cracks resulting in product failure.

Applications

NORYL resins offer a good balance of mechanical and chemical properties, and may be suitable for a wide variety of applications such as in electronics, electrical equipment, coating, machinery, etc.

One of the most famous applications of NORYL was the molded case of the original Apple II computer.  At that point, the product was referred to internally at Apple (1978) as "GE NORYL".  A famous picture of an Apple II was made after a fire almost completely melted the NORYL case, but the motherboard, when removed from the case, was found to still operate.

NORYL resins have possible applications in the production of hydrogen, where it could serve as cost-effective electrodes in an electrolyzer, replacing expensive rare elements. It is highly resistant against the alkaline potassium hydroxide. For conductivity, the plastic is sprayed with a nickel-based catalyst.

NORYL resins are being investigated as a possible replacement for polycarbonate used in the manufacturing of Blu-ray Discs.

It is also used in certain construction products, like water pumps for swimming pools.

RoboSport. RoboSport is a 1991 turn-based tactics computer game. It was created by Edward Kilham and developed and published by Maxis.

The player creates teams of robots and maneuvers them around a board to map out one "turn" of movement. The other players and AI do the same and then all movement is played out simultaneously. The robots are equipped with different weapons, including rifles, grenade launchers, and so on. The game supports multiple modes such as capture the flag and a "hostage" game.

Maxis developed this game for DOS, Macintosh and Windows 3.x. In 1992, it was converted by The Dreamers Guild and released for the Amiga.

Reception

The game was reviewed in 1991 in Dragon #172 by Hartley, Patricia, and Kirk Lesser in "The Role of Computers" column. The reviewers gave the game 5 out of 5 stars. Computer Gaming World praised the Windows version of RoboSport for its excellent user interface, ease of programming, and quick play. The magazine concluded that it was "at least three excellent games crammed into one nearly seamless sport". A later article reported that the game depicted small arms and combined arms tactics better "than many computer wargames dedicated to the subject". A 1994 survey in the magazine of strategic space games set in the year 2000 and later gave the game three-plus stars out of five. Alfred Giovetti, writing for Compute!, praised the game for the flexibility of programming computer robots that would then fight providing an interesting outcome.

Hawthorne Municipal Airport (California). Hawthorne Municipal Airport  (also known as Jack Northrop Field) is a public use airport in Hawthorne, California, United States. It is owned by the city of Hawthorne.

History 
The name "Jack Northrop Field" comes from the Northrop Aircraft Corporation, founded by Jack Northrop, which for years designed, built and flew many classic airplanes including YB-35 flying wing, the P-61 Black Widow and F-89 Scorpion night fighters, the F-5 Freedom Fighter, and the T-38 Talon jet trainer.

During World War II, the airfield was used by the United States Army Air Forces Air Technical Service Command as an aircraft modification center and Air Transport Command to ferry new aircraft to operational units.

SpaceX and its spinoff The Boring Company are headquartered at the southeast end of the airport. The Boring Test Tunnel runs just under the fence line at the north-east corner before running under West 120th Street. The Tesla Design Studio is located at the airport as well.

Facilities 
The airport covers ; its one runway, 7/25, is  concrete. It is effectively crammed into a very small space and is surrounded by residential areas on all sides. The airport is also in very close proximity to the considerably larger Los Angeles International Airport, so special consideration must be given attention to avoid encroaching on the LAX airspace.

There is one fixed-base operator (FBO) at the airport, Jet Center Los Angeles, a subsidiary of Advanced Air. There is also one other aviation related business on the airfield, Star Helicopters.

Airline and destinations

Ground transportation
The Crenshaw station is walking distance from the airport. Several Metro bus lines also run along Crenshaw Boulevard.

Tintic Standard Reduction Mill. The Tintic Standard Reduction Mill—also known as the Tintic Mill or Harold Mill—built in 1920, and only operating from 1921 to 1925, is an abandoned refinery or concentrator located on the west slope of Warm Springs Mountain on the southern edge of Genola, Utah, United States. In 2002, the Utah Department of Environmental Quality tested the soil and found it contained high levels of arsenic and lead, which can lead to serious health problems and even death.

Description

The mill was designed and built by  W. C. Madge. It is significant as the only American mill using the Augustin process during the early 1920s. Metals processed at the mill included copper, gold, silver, and lead, all of which were received from another mill near Eureka. The metal content of ore was increased through the process to make transportation less expensive. The reducing process used was an acid-brine chloridizing and leaching process which became outdated, leading to the abandonment of the site in 1925. At the mill's highest productivity it processed 200 tons of ore daily from the Tintic Mining District.

What remains of the mill are foundations for water tanks, crushers, roasters, iron boxes, leaching tanks, and drain boxes. The site dominates the surrounding landscape with its size and unique colors and shapes. It has been speculated that the mill may be the contributor of heavy metal pollution in the Warm Springs which lie below it.

It was listed on the National Register of Historic Places September 13, 1978.

Yokosuka H5Y. The Yokosuka H5Y (short designation) or Yokosuka Navy Type 99 Flying Boat Model 11 (九九式飛行艇, 99shiki hikōtei) (long designation), given the allied code name Cherry, was an IJNAS flying boat in service from 1938.

Design and development
The H5Y was designed by Yokosuka to meet an Imperial Japanese Naval Air Service's requirement for a twin-engine maritime reconnaissance flying boat, which was intended to match the performance of contemporary four-engine flying boats while being cheaper to build and easier to maintain. Two prototypes were built at the 11th Naval Arsenal, Hiro, being completed in 1936.

The H5Y was a twin-engine parasol wing aircraft, and thus resembled a scaled-down version of the Kawanishi H6K "Mavis". Performance was found to be poor however, with the aircraft underpowered and suffering from structural problems, which delayed production. Only twenty were built between 1936 and 1941. Yokosuka Naval Air Arsenal built the aircraft at the Dai-Juichi Kaigun Kokusho facility.

Operational history
The H5Y was accepted for production in 1938 as the Type 99 Flying Boat Model 11, production deliveries starting in 1939. However, production was quickly cancelled owing to the poor performance, with only twenty being built. Although some were used for coastal anti-submarine patrols early in World War II, they were quickly transferred to second-line duties such as transport or training.

Aichi H9A. The Aichi H9A (二式練習飛行艇, Navy Type 2 Training Flying Boat) was an Imperial Japanese Navy Air Service flying boat used during the first years of World War II for crew training. An uncommon type, it was not encountered by Allied forces until Spring 1945 and was never assigned an Allied reporting name.

Design and development
The H9A was a twin-engined, parasol-wing flying boat, designated by Aichi as their AM-21 design, and it was designed in response to an Imperial Japanese Navy requirement for an advanced seaplane trainer for future crew members of the four-engined Kawanishi H8K "Emily" flying boat. Design work started in January 1940, and the first of three prototypes was flown in September 1940. The aircraft had a normal crew of five (pilot, co-pilot, observer, flight engineer, and a radio-operator), but seating was provided for an additional three pupil crew members.

Operational history
From May – June 1942, the Aichi H9A was employed in a variety of second-line roles, including anti-submarine missions along the Japanese coasts, transport, paratroop training, and liaison.

Variants

Mitsubishi 3G8 engine. The Mitsubishi 3G8 engine is a range of three-cylinder powerplant from Mitsubishi Motors, introduced in the fifth generation of their Mitsubishi Minica kei car. In common with other contemporary engines in the class, it could be specified with many advanced technologies despite its diminutive size, including multi-valve cylinder heads and double overhead camshafts. The top-of-the-line Dangan ZZ variant was also the first kei car to benefit from turbocharging. In 1987 Mitsubishi was the first manufacturer to supercharge a kei vehicle, and in 1989 became the world's first production car to feature five valves per cylinder, ahead of similar developments by Bugatti, Audi, Ferrari and Toyota.

Its 3G81 three-cylinder engine has a displacement of  and the 15-valve versions feature three intake valves and two exhaust valves incorporated into each cylinder. The valves are controlled by twin overhead camshafts through roller cam followers on finger rockers with hydraulic automatic lash adjusters. Gasoline is electronically injected through triple-jet nozzles (also a technological first). The water-cooled turbocharger operates through an air-to-air intercooler. The ignition timing advance is also controlled electronically, and a knock-sensing system is included.

Originally a  engine, it was enlarged to  in 1990 following changes in the class regulations. The four-cylinder 4A3 engine is derived from the 3G8, sharing a  bore pitch.
