Title: Plasma jet ignition system
Inventor: CHINZEI NOBUO
IPC: F02K9/95
Filed: 1989-02-08
Abstract: PURPOSE:To enable a combustion promoting effect to be as high as possible by constituting a plasma jet ignition system of an ignition nozzle body, a working fluid supply means, an arc generating electrode and a plasma accelerating means. CONSTITUTION:Working fluid containing supplied oxygen is set to the plasma state by an arc generating electrode 8 of an ignition nozzle body 6 and accelerated sufficiently by a plasma accelerating means 9 to be jetted deeply into a combustor 1. This jetted plasma injection promotes the combustion of burnt fluid flowing in the combustor with supersonic speed by the thermal and kinetic energy and chemical reaction promoting effect along with active group generation to enable ignition. Also, since the working fluid provides plasma by the arc generating electrode 8 having a negative metal electrode 12 for promoting the formation of a high melting point oxidized film, the negative electrode 12, when the working fluid containing oxygen is used, promotes the formation of the high melting point protective oxidized film on the surface without being damaged by the arc so that stable plasma jet can be injected for a long time.

Title: Pulley device for washer
Inventor: SHIKAMORI TAMOTSU
IPC: D06F37/30
Filed: 1978-03-13
Abstract: PURPOSE: To provide a washer for preparing an inexpensive pulley having the excellent strength, by forming a pulley, which transmits the rotation to a pulsator, so that a plastic belt sheave will be secured at a circumference surface of a metal base plate punched in a polygon.  
     CONSTITUTION: A fixing hole 28 is perforated at a center of a base plate 27 which is of a metal plate being punched in approximately a quadrilateral. Cut parts 30 and holes 33 are made at the corners 29 of the base plate 27, and water drainage holes 35 are perforated at more inner place from the cut parts and the holes. A plastic belt sheave 3 extending more outwardly than an outer circumference of a belt is secured at a circumference suface of the base plate 27. Ribs 34 are radially located at the outside of the belt sheave 32. Since the belt sheave 32 has a minimum lap with the base plate 27 and has the cut parts 30, corners 29 and holes 33, it does not run idle, parting from the base plate 27, while the shaft is rotating. The use of the pulley can be expected to bring about a sound-absorbing effect.

Title: Production of phosphor for el
Inventor: TANABE AKIRA
IPC: C09K11/08
Filed: 1988-02-10
Abstract: PURPOSE:To prepare a phosphor for EL having improved brightness and prolonged life, by adding copper as an activator to zinc sulfide, firing the mixture in two stages, i.e., particular high-temp. firing and low-temp. firing. CONSTITUTION:This process for preparing a phosphor comprises adding copper as an activator to zinc sulfide and firing the mixture, wherein the firing is conducted in two stages, i.e., high-temp. firing at 900-1,100 deg.C and low-temp. firing at 500-800 deg.C. When a large amt. of Cu is added at once, a large amt. of CuXS precipitates on the surface of ZnS, which brings about at lowering in the brightness. By contrast, the present process is characterized in that Cu is added in two stages to prevent CuXS from precipitating in a large amt. during high-temp. firing. Specifically, in the first firing (high-temp. firing), Cu is added in an amt. necessary for effecting electroluminescence to attain a particle diameter sufficient as a phosphor and, in the second firing (low-temp. firing), a suitable amt. of Cu is again introduced into ZnS. Since the treating temp. is low, precipitation of a large amt. of CuXS can be prevented. Thus, it is possible to improve the brightness and prolong the service life.

Then, a gate insulating film 16 is formed by a plasma CVD method or the like; after that, a metal film 19 for gate electrode use is formed on the gate insulating film 16 by a sputtering method or the like. The metal film 19 is irradiated with a laser beam to flatten the surface; after that, it is etched in the film-thickness direction until the surface of the gate insulating film 16 is exposed. Then, a gate electrode 17 which is not overlapped with the source electrode 14 and the drain electrode 15 is formed on the gate insulating film 16. As a result, a parasitic capacity between the gate and the source as well as between the gate and the drain can be reduced.
