IPC: H02H7/18
Filed: 1993-06-08
Abstract: PURPOSE:To provide a composite protective element and a battery pack having the composite protective element capable of securing safety and reliability in the short circuit, overcharge, or reverse charge state of a battery. CONSTITUTION:A PTC element 4 and a fuse 15 are arranged in combination in the circuit from a power generating element to an apparatus, and the PTC element 4 is tripped to suppress a short circuit current before the fuse 15 is fused at the time of a short circuit. When a battery is overcharged or reversely charged by abnormally high voltage to cause the dielectric breakdown of the PTC element 4, the fuse 15 is fused to surely cut off the current, and the breakage of the battery is prevented by this composite protective element.

Title: Vacuum interrupter
Inventor: NODA TAIJI
IPC: H01H33/664
Filed: 1988-06-06
Abstract: PURPOSE:To improve the interrupting performance and the possible number of interruption, by providing a groove, connected to a spiral groove having a width smaller than that of the spiral groove, in a minor diameter side recess of an annular contact portion of a spiral electrode. CONSTITUTION:In a minor diameter side recess 16 of an annular contact portion 14, a groove 12b having a width smaller than that of a groove 12a is cut up to the minor diameter side end of a taper portion 16a. Therefore, the inner end side of the spiral groove 12b is never exposed to the arc. Thus, the inner end of the groove can be at electrode center side without lowering the overall electrode strength, and the interrupting performance and the possible number of interruption can be improved simultaneously.

Filed: 1992-04-14
Abstract: PURPOSE:To provide the sand core which withstands a high casting pressure at the time of casting by coating the surface of a sand core prototype with a slurry-like coating material consisting of a neutral water dispersion essentially consisting of powdery refractories. CONSTITUTION:The sand core prototype contg. an inorg. salt is molded by compounding the inorg. salt or into resin coated sand coated with a synthetic resin of a carbolic acid and curing the mixture by heating. The surface of the sand core prototype is coated with the slurry-like coating material consisting of the neutral water dispersion essentially consisting of the powdery refractories.

This coating is dried to form the coating layer having a uniform thickness. The failure of the sand core by a molten metal and the infiltration of the molten metal into the sand core are obviated even under a high pressure such as in high-pressure die casting.

Title: Monitoring device using optical transmission line
Inventor: KUME NOBORU
IPC: H04B10/2581
Filed: 1993-06-10
Abstract: PURPOSE:To provide a monitoring device which can monitor plural areas that may possibly generate the heat on a single thermal fusing type optical transmission line with high using flexibility and performance by providing an optical transmission line which is placed close to a monitored part with its bent middle part and receives the input of light from an optical transmitter means and an optical receiver means which receives the light through an end part of the optical transmission line and converts the light into an electric signal. CONSTITUTION:The light emitted from an LED 11 of an optical transmitter circuit 10 is received through an optical input end 31 of an optical transmission line 30 and then transmitted through an optical output end 32 after passing through the line 30 set along a monitored part. Thus the light of the LED 11 is received at the base of a phototransistor 21 of an optical receiver circuit 20. If this light is attenuated or eliminated at the base of the phototransistor 21, the collector-emitter current is reduced or eliminated or the output is inverted. Therefore the monitoring output 41 has a high potential. Under such conditions, a control signal is acquired to actuate an alarming or protecting circuit.

Title: Fuel supply control method for engine
Inventor: NIWA TAKAO
IPC: F02D41/04
Filed: 1983-07-28
Abstract: PURPOSE:To prevent the increase of NOx in exhaust gas and the lowering of acceleration performance as well as improve fuel cost by controlling an engine such that an air fuel ratio is a theoretical one when detecting the acceleration state of the engine even in a prescribed light load region. CONSTITUTION:A control circuit 20 corrects to increase an output when a basic injection amount Tp evaluated from the number of engine revolutions, the amount of intake air and constants is more than a first set value Tpbeta. If small, it is compared with a second set value Tpalpha, if larger than Tpalpha, a correction by feedback control is conducted. If less than Tpalpha, it is evaluated with the previous processing. Further, said control circuit compares a basic injection amount Tpn-1 stored in a RAM206 with the preset basic one Tpn, and corrects to decrease the injection amount if Tpn is less than Tpn-1, thus allowing an air fuel ratio being leaner than a theoretical one. If the present basic injection amount is larger than the previous one, i.e., at acceleration, feedback control is conducted, and open rule control is not conducted, so that it is possible to prevent the lowering of the acceleration and NOx and improve fuel cost.

Abstract: PURPOSE:To aim at improving the accuracy of air-fuel ratio control by measuring the fuel flow values of plural fuel injection valves so as to classify them into groups and assembling the fuel injection valves of the same group to a cylinder corresponding to one exhaust density detector.
