IPC: B60L9/28
Filed: 1984-01-12
Abstract: PURPOSE:To shorten the restarting time of an inverter by using a thyristor for a shortcircuiting unit of a charging resistor, thereby preventing the capacitor from overcharging. CONSTITUTION:A thyristor 5A is connected in parallel with a charging resistor 4, and a voltage detector 7 is connected in parallel with a capacitor 3. When a DC voltage is initially applied, a thyristor 5A is turned OFF, the capacitor 3 is charged by a current fed through the resistor 4, and the charging voltage is detected by the detector 7. After the voltage is higher than the second prescribed voltage E2 and the charging time T0 is elapsed, a gate signal is outputted to the thyristor 5A to shortcircuit the resistor 4, the inverter 1 is operated to supply power to a load 9. When the power is interrupted, with the capacitor 3 as a power source the inverter 1 is operated, but when this voltage drops to the prescribed voltage E0, the operation is stopped, and the thyristor 5A is turned OFF. The similar operation is performed when the voltage is reapplied.

Filed: 1987-01-08
Abstract: PURPOSE:To prevent an electric current from leaking to a P-type substrate by a method wherein a P-type impurity diffused layer is formed along an N<+> contact layer at the outside of a P-base layer which is short-circuited with an emitter by using an anodic conductor and this P-type diffused layer is connected to the N<+> contact layer by using a cathodic conductor. CONSTITUTION:P-type impurity diffused layers 8 are formed along the inside of N<+> contact layers to be connected to cathodic conductors; in addition, they are connected to the cathodic conductors 11 together with the N<+> contact layers 6. The P-type impurity diffused layers prevent holes, which are injected from a P-base layer 4 into an N<-> layer 3, from passing through the N<+> contact layers 6; they limit the occurrence of the effect of a parasitic PNP transistor due to a P<+> device isolation layer 7, an N<-> epitaxial layer 3 and a P-base layer 4. As a result, it is possible to prevent a leakage current from flowing to a P-type substrate.

Abstract: PURPOSE:To find a failure early by displaying an operating status of a circuit for discharging a capacitor after operation of an adjusting and operation checking device of a substrate block. CONSTITUTION:A capacitor 2 to be discharged which requires discharging after operation of a substrate block 1 to be checked is connected to a discharging relay 7 and a discharging resistor 8 of an adjusting and operation checking device 11 by contact pins 3,4.

Then electric charge remaining in the capacitor 2 is connected to the resistor 8 through the pins 3,4 to be discharged. That is, during adjustment and operation checking, an indication diode 10 lights up, and it goes out when the switch 6 is set to an operation completion step. However, the diode 10 stays unlit or lit in case of failures such as incorrect connection or line breakage, easily indicating that this discharge circuit is broken down.

Filed: 1989-01-09
Abstract: PURPOSE:To reduce a write-in current corresponding to the reduction of the area of a programmable element and to attain stable writing by switching an opening/closing circuit to absorb the write-in current in a prescribed cycle. CONSTITUTION:When the write-in current flows, an oscillation circuit 3 of an opening/closing control circuit 6 is activated, and in the other time, the circuit 3 is made into an inactive state. Since the oscillation waveform of the circuit 3 becomes the input signal of an opening/closing circuit 1, the selected circuit 1 executes a switching operation in an oscillation cycle. Further, the selected opening/closing circuit 1 becomes a low level and can absorb the write-in current. The aluminum spike caused by heat generation by the write-in current is generated in junction short-circuit programmable elements QC11-QC14 and QC21-QC24, and the programmable elements short-circuit a base-emitter junction. Since an oscillation frequency can be arbitrarily set for the circuit 3, the writing can be executed under a write-in condition suitable for the programmable elements by adjusting the oscillation frequency.

Title: Insulation deterioration diagnosing method for oil-filled electric equipment
Inventor: ABE KEIICHI
IPC: G01N30/88
Filed: 1987-01-12
Abstract: PURPOSE:To accurately diagnose the insulation deterioration of insulating oil of oil-filled electric equipment which uses the insulating oil by measuring the mean molecular weight of the insulating oil and diagnosing the insulation deterioration from variation in the mean molecular weight. CONSTITUTION:When the insulating oil deteriorates, a thermally unstable component of the insulating oil separates and its decomposed product reacts to a thermally stable component, so that the mean molecular weight of the insulating oil increases. The mean molecular weight of the insulating oil is measured to grasp the deterioration state of the insulating oil. The mean molecular weight is measured directly by liquid chromatography (HPLC). Namely, the insulating oil where a solvent is dissolved is injected into a column where particle fillers having pores of the nearly the same size with molecules of sample insulating oil is charged and components which are high in molecular weight move in the column faster than those which are low in molecular weight and are dissolved; and data are analyzed by using an obtained curve to obtain a molecular weight distribution graph, from which the mean molecular weight is calculated.

Title: Variable poles type revolving electric machine
Inventor: IKUNO HIROSHI
IPC: H02K17/14
Filed: 1979-01-18
Abstract: PURPOSE: To obtain a large number of poles in a small size by forming particular fractional-slot winding in high speed, while providing single winding in low speed so as to form intermediate poles in the relations where the number of slot in one pole and one phase is smaller than one, the ratio of pole number being 1:2.  
     CONSTITUTION: Supposing that the number of slot of stator Z is 36, the number of pole as 10 and 20, and the number of phase as lapped winding of 3 phases, and that connection is 2×Y in the case of 10 poles, the number of slot per one pole and one phase is expressed as g=Z/(m×P)=1.2. Accordingly, the winding pitches of the phases U, V and W being considered as 2, 1, 1, 1, 1, 2, 1, 1, 1, 1 respectively and the terminals U 1 , V 1  and W 1  being short-circuited, the particular fractional winding without intermediate magnetic pole is formed. In the case of 20 poles, the number of slot per one pole and one phase is smaller than 1. However, by opening terminals U 2 , V 2  and W 2  to make the connection 1×Δ, intermediate poles are formed and thus 20 poles are obtained.
