Title: Minute structure of polycrystalline wsi2 film
Inventor: TANIGAWA AKIO
IPC: H01L21/3205
Filed: 1986-08-26
Abstract: PURPOSE:To obtain a WSi2 film having low resistance, by orienting crystal grains. CONSTITUTION:After ordinary washing is performing with acid, the surface of a P-type (511) Si substrate 2 is cleaned with dilluted fluoric acid treatment. The substrate 2 is heated in an evaporating apparatus to evaporate W. Thus, a WSi2 film which has the directivity that crystal grains are oriented to the same direction can be formed. In the case of a half-metallic material such as WSi2, scattering of a grain boundary can be made weak by orienting the crystal grains. Therefore, the resistance can be reduced by orienting the crystal grains.

Abstract: PURPOSE:To compensate a decrease in the amount of fuel injection due to blockage of a nozzle section to avoid lowering the performance of an engine up fully opening operation, in an electronically controlled fuel injection device in a spark ignition type internal-combustion engine, by injecting fuel from two injection valves in the identical time period. CONSTITUTION:Two fuel injection valves 3, 4 positioned upstream of an intake- air throttle valve 2 are operated under feed-back control for the injection amount of fuel by means of a control circuit 7 in accordance with a signal from an oxygen sensor 21 disposed in an exhaust passage 6 so that a mixture for the stoichometric air-fuel ratio of the engine is produced. Normally, drive control is made such that fuel is injected from both fuel injection valves 3, 4, alternately. When the oxygen sensor 21 informs such an indication that the air-fuel ratio is successively deviated for a predetermined time period toward the lean side of mixture, a judging circuit and a compensation comuting circuit controls two injection valves 3, 4 so that fuel is injected from both valves 3, 4 in the identical time period, and the injection cyclce numbers thereof are increased. With this arrangement, even if the injection valves 3, 4 are blocked, it is possible to avoid lacks of supply fuel upon high output power operation, etc.

Title: Electrolysis with addition of ultrasonic vibration
Inventor: YOSHIKAWA AKIRA
IPC: C02F1/467
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To efficiently recover a metal from soln. of low ion concn. by adding ultrasonic vibration on electrodes and an electrolytic liquid. SOLUTION: When ultrasonic vibration at >=20kHz frequency is continuously or intermittently added to electrode or electrolytic soln. having <=1g/l metal ion concn. for which electrolysis is conventionally regarded difficult, the following effects can be obtd. A diffusion layer on the electrode surface is broken and minimized to increase the metal ion concn. on the electrode surface, which increases the limiting current density and suppresses the contention reaction. Moreover, the electrode surface is activated and the surface of the electrodeposited metal is always smoothened. Further, bubbles of the gas produced on the electrode surface are immediately removed to prevent decrease of the surface area. The drift speed of ions in the soln. is increased. By various effects above described, valuable metals can be recovered from factory waste water and the like having low ion concn.
