Title: Power source protecting circuit
Inventor: MUKAI SHINJI
IPC: H02H3/24
Filed: 1987-05-08
Abstract: PURPOSE:To protect a power circuit from excess current at the time of the lowering of a load impedance and the short-circuiting of the load, by inserting a diode into a space between the power-ON/OFF terminal of a micro-computer in a stand-by circuit, and a power output line. CONSTITUTION:With a power circuit provided with a switching regulator 4, its controlling circuit 5, and a stand-by circuit 12, a diode 13 is inserted into a space between the power-ON/OFF terminal 10 of a micro-computer set in the standby circuit 12, and a power output line. The direction of the diode 13 is set so that it may be turned ON at the time of the lowering of the impedance of a load 11 and the short-circuiting of the load. As a result, when the load short-circuiting or the like is generated, then the diode 13 is turned conductive, and the switching regulator 4 is turned OFF via the controlling circuit 5, and so the power circuit can be protected so that excess current cannot flow through the circuit.

Title: Surface hardening method of steel
Inventor: TANIGUCHI HIROSHI
IPC: C23C8/34
Filed: 1978-09-14
Abstract: PURPOSE:To reduce treating time and labor and improve quality by subjecting steel to gas soft nitriding at a temperature below A1 transformation point then raising its temperature in the same furnace in succession and subjecting the same to gas carburizing and quenching or gas carbonitriding. CONSTITUTION:After steel is subjected to gas soft nitriding at the temperature below its A1 transformation point, it is raised of temperature in the same furnace in succession and is subjected to gas carburizing and quenching or gas carbonitriding at the temperature above its A1 transformation point. Thereby, the layer of Fe-N base compound (Fe3N, Fe4N, etc.) and the martensite layer of Fe-C-N layer are formed on the steel surface and yet multiple fine voids are created near the surface. According to this method, gas carburizing and quenching are accomplished after gas soft nitriding and therefore more voids are formed in the surface layer as compared to conventional processes, hence this blank permits impregnation of lubricating oil when used for friction material, resulting in considerably reduced friction force.

Title: Choke valve control unit of carburetor
Inventor: NAKAZATO KAZUO
IPC: F02M1/14
Filed: 1983-06-23
Abstract: PURPOSE:To prevent the air-fuel ratio from becoming excessively dense by increasing the opening of a choke valve as compared with the case under a low load during acceleration at the engine cold start in a negative-pressure actuator- type choke valve. CONSTITUTION:A chock valve 3 closed while an engine is stopped applies a negative pressure to a diaphragm 7 through a pipe 12 and a throttle 11 via the full explosion during the engine start and pulls a rod 4, which rotates the chock valve 3 in the open direction. At this time, since the engine temperature is low, a servo valve 21 is opened, a negative pressure switch 22 is turned on due to a strong negative pressure, a valve 23 is opened, and further, a valve 20 is opened due to the movement of the rod 4. Therefore, the negative pressure in a diaphragm chamber partially leaks into the atmosphere through the valve 20, pipe 13, valves 21, 23, thus setting the chock valve to a predetermined opening. During acceleration under this condition, the negative pressure switch 22 is turned off, and the leak of the negative pressure of the said diaphragm chamber is stopped, thereby the rod 4 is strongly pulled, and the choke 3 is kept at a slightly opened opening.

Title: Piezoelectric diaphragm
Inventor: KAWASAKI KOUZOU
IPC: H04R17/00
Filed: 1984-06-01
Abstract: PURPOSE:To obtain an excellent required band characteristic by adhering a piezoelectric element to the inner flat face or its rear face of a non-circular recessed part being in the outer peripheral shape formed to an elastic thin plate so as to attenuate remarkably the high-order resonance level. CONSTITUTION:A metallic plate 5 forms a dish as an elastic thin plate and the recessed part 6 whose outer peripheral shape is non-circular and circular piezoelectric element thin plate 2 is adhered on a plane 7 in the recessed part 6. When the plane with a recessed part is a non-circle such as ellipse or oblong circle, the resonance frequency of the major axis and the minor axis is different. Although the difference of the resonance frequency at the major axis and the minor axis is not so much large, the high-order resonance is larger in comparison with the 1st resonance and the energy of resonance is scattered. Then the high-order resonance level is attenuated remarkably by selecting the ratio of the major and minor axes to apropriate value.
