Title: Protecting circuit
Inventor: INATOMI SHIYOUICHI
IPC: H01L33/00
Filed: 1982-03-19
Abstract: PURPOSE:To effectively prevent the damage of an element to be protected and the deterioration of the characteristics by equivalently reducing the response delay of a Zener diode, thereby rapidly absorbing the abnormal voltage. CONSTITUTION:When an input voltage V1 rises reversely to a Zener diode ZD, the operating point of the diode ZD enters a Zener range, and a diode D1 becomes ON. Thus, the output voltage V2 which is presented at the output terminals 2, 2 is clamped to the voltage added by the Zener voltage VZ of the diode ZD and the forward voltage VAK between the anode and the cathode of the diode D1. When the input voltage V1 rises forwardly to the diode ZD, the diode ZD becomes ON, and a diode D2 becomes ON. In this manner, the output voltage V2 is clamped to the voltage added with the forward voltage VAK, VAK between the anode and the cathode of the diodes ZD and D2. Consequently, even if an abnormal voltage is applied to the input terminals 1, 1, a voltage not lower than the voltage clamped by a clamping circuit is not outputted to the output terminals 2, 2, thereby preventing the damage of a light emitting element.

Title: Ion implanting apparatus
Inventor: TANAKA MAKOTO
IPC: C23C14/48
Filed: 1985-03-05
Abstract: PURPOSE:To prevent discharge between the insulation film and the substrate of semiconductor wafer by stopping ion beam irradiation and switching to electron beam irradiation upon exceeding of the quantity of impurities implanted into a semiconductor wafer over predetermined level. CONSTITUTION:An ion implanting apparatus is additionally provided with an electron beam generator 42 having an electron source 41. Then positive ion beam of impurities 3 is irradiated from the positive ion source 31 to a semiconductor wafer 1 formed with an insulation film on the surface while placed in a vacuum chamber 8. The quantity of implanted impurities is counted through a counter 7, and upon exceeding over a setting level, ion beam irradiation is stopped to irradiate electron beam 4 from the electron source 41 thus to charge down the insulation film. Consequently, discharge between the insulation film and the substrate of wafer 1 is eliminated through alternative irradiation of ion beam and electron beam resulting in improvement of production yield.

Title: Windshield wiper for automobile
Inventor: MIYAMOTO TARO
IPC: B60S1/08
Filed: 1989-02-28
Abstract: PURPOSE:To perform reciprocating speed regulation for a wiper blade automatically so as to improve the of driving safety by constituting a wiper control part to drive a wiper unit according to a rainfall or the like detected by a railfall detecting element. CONSTITUTION:When a driver operates a controlling element 3, starting a wiper control part 2, and a wiper unit 1 is made to come into an operable state, a rainfall detecting element 4 generates a signal conformed to a railfall sent down, delivering it to the wiper control part 2.

Title: Engine generator
Inventor: TARIKI KEIJI
IPC: F02D29/06
Filed: 1987-03-02
Abstract: PURPOSE:To sufficiently decelerate an engine at the time of no load of a generator and to remarkably reduce noise and fuel cost by closing an exhaust control valve when load current of the generator is substantially zero. CONSTITUTION:In a generator 34, when external load is released from a plug socket 40, load current detected by a current detector 42 becomes substantially zero to be in no-load state. At this time, a solenoid valve 46 is excited to operate an actuator 44, so that intake negative pressure is conducted to a diaphragm 48. Therefore, an intake throttle valve 12 is closed to decelerate an engine to the idling speed. At this time, an exhaust control valve 20 is closed to a totally closed position so that the exhaust passage area is throttled about the half. Thus a negative pressure wave which is generated at the release end of an exhaust pipe 16 and turned and a positive pressure wave which is reflected by the exhaust control valve 20 cancel each other to let the sum be zero, so that idling operation is stabilized. Accordingly, the idling speed can be decreased so as to reduce noise and improve fuel cost.

Title: Oxygen potential self-control type nuclear fuel compound
Inventor: MUROMURA TADASUMI
IPC: G21C3/62
Filed: 1993-03-05
Abstract: PURPOSE:To enhance the performance of a nuclear reactor for power plant by dispersion sintering a molybdenum metal at a specific rate to a dioxide based nuclear fuel compound thereby allowing self control of oxygen potential to a constant level during nuclear fission. CONSTITUTION:A dioxide based nuclear fuel compound means an uranium dioxide (UQ2) and an uranium dioxide added with several % of adolinium (Gd2Q3) is also used partially. A dioxide mixed with uranium and plutonium ((U, Pu) Q2) is also a nuclear fuel. For example, 1.7-5.1wt.% molybdenum metal is dispersed to 98.3-94.9wt.% uranium dioxide and sintered. Consequently, two phases of uranium dioxide and molybdenum metal are chemically balanced to produce a nuclear fuel compound in two phase coexisting state. Oxygen potential of such nuclear compound can be controlled based only on the temperature not on the degree of burn-up. Consequently, stability of nuclear fuel is enhanced thus enhancing the degree of burn-up. Furthermore, the stability of nuclear fuel can be evaluated easily.

CONSTITUTION:A heating body of a thermal head is formed of a tantalum nitride layer 3, and an oxidation-resisting layer to be provided thereon is formed of a plasma-oxidized film 5, while an abrasion-resisting layer is formed of a plasma oxynitride film. When a plasma CVD method is applied, an SiO film and  an SiN film are formed at a film-forming temperature of 250-300 deg.C on a substrate whereon they are desired to be formed. In addition, the speed of forming  the SiO film is about 500Angstrom /min, and that of forming the SiN film is about  300Angstrom /min. These are about six times and 1.3 times higher than those obtained  when an RF spattering method is applied. The SiO film can be formed in a gas  system of SiH4+N2O, and the SiN film in a gas system of SiH4+NH3+N2. In  order to prevent the SiN film from cracking, it is formed into an SiON film by  introducing oxygen (about 10% in a system of N2O/NH3+N2O).

Abstract: PURPOSE: To quickly absorb vibration impact due to large horizontal and vertical relative motions by arranging an end of each tube spaced from a bottom of a damper housing and by arranging a supporting member on an outer peripheral wall of the damper housing. CONSTITUTION: A vibration damper comprises a damper housing 2 in which a cylinder peripheral wall 9 is fixed to a bottom plate 3, and a damper ram 4 having a cover plate 1, wherein the damper ram 4 is put within the damper casing 2 and on the bottom plate 3.
