IPC: C23C14/34
Filed: 1992-02-28
Abstract: PURPOSE:To produce the target for sputtering having a high density and a long life by packing a powder mixture composed of In2O3 and SnO2 into a capsule and compacting the capsule at and under a specific temp. and pressure, then subjecting the capsule to normal sintering at a high temp. CONSTITUTION:A dispersant is compounded with the raw material powder mixture consisting of 10wt.% In2O3 and 10wt.% SnO2 to prepare a slurry. This slurry is sufficiently mixed and is dried; thereafter, the dried mixture is packed into the capsule having fine vent holes. After the cap of the capsule is welded to the capsule, the capsule is compacted at least at >=500 deg.C at which the In2O3, is not decomposed and under >=70MPa pressure in the atm. In succession, this capsule is sintered at >=1350 deg.C in the atm., by which the high-density and large- sized ITO sputtering target having the long service life is produced.

Title: Throttle type fuel injection valve
Inventor: SAKAI YASUROU
IPC: F02M61/06
Filed: 1982-03-18
Abstract: PURPOSE:To suppress combustion noise and to prevent deterioration of the engine stability by forming a tapered surface, the angle of taper increasing as approaching the injection port, at the throttle part of valve element and the injection port and thereby always maintaining good preliminary injection. CONSTITUTION:The angle theta1 of a tapered surface 13A at the injection port 6 is formed larger than that theta2 of the tapered surface 13B at the throttle part 4. Accordingly ring-shaped gap 8 between the jet hole 6 and throttle part 4 increases proportional to the increment in the lift of valve element 2. As a result, eventual production of carbon layer 14 attached to the valve seat 1, jet hole 6 or throttle part 4 does not hinder microjetting of the fuel in valve chest 9 through this increasing gap 8 even with a minor lift because the width of the gap 8 increases as the valve element 2 lifts. Thus a secure preliminary injection is obtained.

Filed: 1982-03-15
Abstract: PURPOSE:To inject an accurate quantity of fuel into an internal combustion engine by an arrangement wherein the flow rate of the fuel cooling a solenoid winding and then flowing out from a fuel injection device is controlled by a pressure holding valve controlled by the regulated fuel pressure to maintain the fuel pressure correctly. CONSTITUTION:A fuel injection device 5 is supplied with a fuel kept at a constant pressure which is supplied under pressure by a fuel pump 1 and regulated by a pressure control valve 6. This fuel is supplied into a region near an injection port b of the fuel injection device 5 from where it is injected into the engine.

IPC: G01T1/20
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To enhance resolution in a CT device by allowing another light separa tor at a specific height from an SPD surface to project between photodiode elements to reduce the light crosstalk between scintillator elements. SOLUTION: The thickness of an optical adhesive layer 3 sticking a silicon photodiode SPD 4 to an emission surface 23 ranges from approximately 1 to 10 μm. Another light separator 42 that is as high as 0.1-2 μm from an SPD surface projects into an optical adhesive layer 2 between photodiode elements 41 for detection on a surface that faces to the emission part 2 of the SPD 4. The light separator 42 is formed by allowing the silicon of the SPD 4 to project or by sputtering heavy metals such as Mo, or W, for lamination. By allowing the light separator 42 to project from the upper surface of the SPD 4 into the optical adhesive layer 3, a so-called light crosstalk can be reduced, in which visible light discharged from a scintillator element 21 is received by an adjacent photodiode element 41 through the optical adhesive layer 3.
