Abstract: PURPOSE:To sharply reduce the manufacturing processes of a side face insulating layer, and also to improve discharge withstand current characteristics by using the insulating material formed by adjustingly mixing powder glass and antimony oxide so as to obtain their mixing ratio of 3: 70 to 70:30. CONSTITUTION:A non-linear resistor element 1a is formed by adding the oxide, consisting bismuth oxide, silicon dioxide, antimony oxide, cobalt oxide, manganese dioxide, chrome oxide, nickel oxide and the like, to the main component of zinc oxide. Then, insulating material is formed by regulatory mixing powder glass and antimony oxide in such a manner that the mixing ratio of 30:70 to 70:30 is obtained, and the mixture is formed into a paste state together with an organic binder and an organic solvent. After the above-mentioned paste-like material has been applied to the surface of the element 1a, a heat treatment is conducted at 500 to 700 deg.C as a baking treatment, and an insulating layer 5 is formed on the surface of the element 1a. Besides, both edge faces of the element 1a are polished, washed by trichloroethane, and an electrode is formed. As a result, a non-linear resistor, having excellent discharge withstand current characteristics can be obtained even when manufacturing processes are sharply reduced.

Title: Alternator
Inventor: KANAZAWA HIROYUKI
IPC: H02P9/00
Filed: 1994-12-22
Abstract: PURPOSE: To detect an abnormality of an alternator by passing output coils of respective phases of the alternator through an inner diameter of a closed magnetic circuit and winding a secondary winding around an iron core of the magnetic circuit and thereby detecting zero-phase current which appears when an abnormality occurs. CONSTITUTION: An alternator 1 is provided with a field coil 4, stator coils 5, diodes 6, a voltage adjustor 7, and a zero-phase current detection iron core 8. The stator coils 5 of three phases are collectively passed through a ring of the zero-phase current iron core 8. A detection coil 81 is wound around the zero-phase current iron core 8. Usually, alternating magnetic fluxes which are 120 deg. out of phase with each other exist in the iron core 8 and these magnetic fluxes cancel each other and therefore no voltage appears in the detection coil 81. However, when troubles such as leakage, shorts, disconnection of the stator coils 5 occur, the alternating magnetic fluxes comes out of balance and AC voltage appears in the detection coil 81. By this method, an abnormality of the alternator 1 can be detected easily.

Title: Temperature measuring instrument
Inventor: SHIRAE KIMISUKE
IPC: H01G7/04
Filed: 1989-12-08
Abstract: PURPOSE:To detect temperature in a constant range according to infrared rays without using any chopper mechanism by making the temperature of a pyroelectric infrared detecting element varies when the infrared rays are supplied from outside and detecting the variation by a temperature detecting means. CONSTITUTION:A C/F converter 7, a frequency measuring circuit 8, and an output transistor(TR) 9 constitute the temperature detecting means 12 which detects temperature according to variation in the capacity of the pyroelectric infrared detecting element 2. Then the temperature measuring instrument is arranged by oppositing a body whose temperature is to be detected and then the infrared rays are made incident on the element 2 through a Fresnel lens 1. Therefore, when the temperature of an object to be detected is about 48 deg.C e.g. 50 deg.C, the temperature of the element 2 itself rises as well and the electrostatic capacity of a capacitor C is decreased. Further, when the temperature of the object is lower than 48 deg.C, the temperature of the element 2 itself is lowered and the electrostatic capacity of the capacity C is increased. Therefore, the temperature of the object which is about 48 deg.C, e.g. 40 - 53 deg.C can be measured according to the output of the converter 7.

Filed: 1988-12-21
Abstract: PURPOSE:To ensure the prevention of re-arcing in interrupting a current flow by monitoring voltage and current waveforms and providing a means for generating a trip instruction upon the coincidence of a voltage waveform peak and a current waveform zero point. CONSTITUTION:When a gas circuit breaker 2 receives a trip instruction signal, flowing current and occurring voltage in a circuit system are monitored with a current waveform monitor 11 and a voltage waveform monitor 12 provided in the system. In addition, the phase of a current zero point is detected with a current zero point detecting circuit 15 and the phase of a voltage peak is detected with a voltage peak detecting circuit 14. The phases so detected are compared with each other in a comparator circuit 15, and when the peak of the voltage waveform agrees to the current zero point, a signal generation circuit 16 sends a circuit breaker trip instruction signal, thereby actuating an operation mechanism. Also, when the peak of the voltage waveform and the current zero point do not agree to each other, the aforesaid comparison is again conducted. When no coincidence occurs within the predetermined time, the signal generation circuit 16 gives a warning signal.

Abstract: PROBLEM TO BE SOLVED: To facilitate inspection of an injection maximum pressure by unevenness in a machine difference by a novel constitution. SOLUTION: A pump 1 is provided with an electromagnetic spill valve 22 to intercommunicate a pump 11 to pressurize fuel through operation of a plunger 10 and a fuel chamber 5 on the low pressure side for terminating fuel injection and a cam angle sensor.
