IPC: G01R27/16
Filed: 1984-12-28
Abstract: PURPOSE:To measure a cable line to be measured in a hot-line state as it is and to take a measurement easily and accurately even when floating capacity is large by applying low-frequency signals of frequencies f1 and f2 for measurement to the cable way through the grounding wire of a transformer. CONSTITUTION:Two oscillators OSC1 and OSC2 of different frequencies f1 and f2 are provided. A new loop connection line LP is provided penetrating a transformer OT and a zero-phase current transformer ZCT so that the line is opposite in phase to the grounding line LE penetrating them. Further, a variable resistor RV and a variable capacitor CV are connected in series with it. Such values of the capacitor CV and resistor RV that the output of a rectifier DET is minimum are measured, and variable resistance value corresponding to the frequencies f1 and f2 are weighted by (f1/f2)<2> and the difference between the both is calculated to calculate the grounding resistance value in the hot-line state as it is. Further, a floating capacity value C0 is obtained from the value of the capacitor CV and an insulation resistance value R0 is calculated from the resistance value RV and the measured capacity value C0.

Title: Variable delivery radial piston pump
Inventor: YAMAMURO SHIGEAKI
IPC: F04B49/00
Filed: 1988-10-31
Abstract: PURPOSE:To obtain a multistage variable delivery without abnormal hydraulic pressure in a variable delivery radial piston pump by dividing the pump into plural sections, and forming each section with a discharge passage to adjust discharge through a direction control valve. CONSTITUTION:In a variable delivery radial piston pump, the whole pump is composed of each unit of a large and a small delivery pump. In the case of small delivery mode actuation, a three position directional control valve 11 is set at a small mode, and a discharge flow from the large delivery pump is returned to a reserving tank 7 to make only the small delivery pump discharge fluid. Next, in a large delivery mode, only the large delivery pump inversely performs discharging action, and in a combined delivery mode, a discharge added up by both the pumps is obtained. In the case where the small delivery mode has been changed over into the large delivery mode, even when ports of a directional control valve are late in communicating with each other, the fluid is supplied through a check valve to a discharge passage 6, and hydraulic pressure does not therefore rise abnormally, and when both the modes have overlapped each other, the check valve closes to prevent pressure drop in the passage 6. Thus multistage variable delivery is obtained without abnormal hydraulic pressure rise and drop.

Title: Electromagnet coil driving apparatus
Inventor: NIWA MASAHISA
IPC: H01F7/18
Filed: 1992-10-15
Abstract: PURPOSE:To realize high speed operation of rotor and ease rebound thereof by adequately attenuating a coil current. CONSTITUTION:While a switch 2 is closed, a pulse signal generating circuit 5 turns off a switching element 4 to keep almost constant a current flowing into a coil 3 by controlling it with a chopper. While the switching element 4 is in the off state, the curernt flowing into the coil 3 is regenerated by a first regenerating circuit consisting of a transistor 7 and a diode 6. When the switch 2 is opened to remove a power supply voltage, the pulse signal generating circuit 5 stops turning off the switching element 4. Moreover, the transistors 13, 7 turn off setting the first regeneration circuit to the non-conductive state. Cut-off condition of the first regenerating circuit attenuates the coil current. Here, the coil current attenuates more slowly than that in the conventional surge absorbing element by properly selecting a zener voltage Vz of a zener diode 8 to a small value.

Title: Operational amplifier input stage
Inventor: KNEE DEREK L
IPC: H03F3/45
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To provide an input stage of an operational amplifier which obtains almost constant transconductance gm that is not influenced by in-phase mode input voltage. SOLUTION: At least one of differential pairs functions against whatever in-phase mode input voltage by using a differential pair 102 that consists of NMOS transistors and a differential pair 104 which consists of PMOS transistors. When in-phase mode input voltage approaches power voltage, one of the differential pairs starts to be off, tail current that flows through the differential pairs changes and then, gm of the differential pair changes. A sense transistor pair 106 is provided so that the sum of the gm of the two differential pairs may always be constant. When one of differential pairs is operated by in-phase mode input voltage and the gm is not constant, which is detected and compensated by adjusting current that flows through the other differential pair. This feedback can keep the total gm of input stages almost constant.

Abstract: PURPOSE:To eliminate the need for battery replacement until the life of a battery ends by using a rechargeable battery as a battery to be incorporated in a pen for coordinate indication and charging the battery when the pen for coordinate indication is not used without detaching the battery. CONSTITUTION:When the pen 2 for coordinate indication is not used and set in the pen stand of a digitizer main body 1 with its tip faceup and facedown, the secondary side coil 11 of the pen 2 for coordinate indication is interposed between the primary coil 5 and iron core 6 of a transformer for charging and coupled with the primary side coil 5 electromagnetically. Consequently, an AC voltage is developed across the secondary coil 11 and rectified and smoothed by a rectifying and smoothing circuit 12, whose output is supplied to the rechargeable battery 7. Therefore, when the pen 2 for coordinate indication is not used, the chargeable battery 7 incorporated in the pen 2 for coordinate indication is always in a charged state. Consequently, the battery need not be replaced until its life ends.
