Title: Device for measuring electrical current of x-ray plant
Inventor: KIWAKI HISAKATSU
IPC: G01R19/00
Filed: 1985-05-17
Abstract: PURPOSE:To easily and accurately measure the electrical current of an X-ray tube, by using a sensor responsive to a magnetic field generated by the electrical current around a high-voltage cable through which the current flows. CONSTITUTION:An electrical current ir flows from a core wire W to an X-ray tube T because of the positive voltage of a power supply P. Since there is an electrostatic capacity between the core wire W and shileds Sh, Sh', the current ir includes currents iCE, iCE' which charge the electrostatic capacity. The charging currents iCE, iCE' are in direct proportion to the length of a high- voltage cable. Since the point of the disconnection of the shields Sh, Sh' is located near the X-ray tube T, the charging current iCE' flowing through the shield Sh' is much less than that iCE flowing through the shield Sh. Because of the point of the disconnection of the shields, the current iCE does not flow to the ground E, so that the current does not act to a sensor So. Since the point of the disconnection of the shields is located near the X-ray tube T, the current iCE' is much less than the current ir. Therefore, it can be said that a magnetic flux which acts to the sensor So is generated by only the current ir. For that reason, the current ir can be accurately measured.

Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To structure a deflection yoke capable of reducing high-order raster distortion by recessing the front crossover of a saddle-type deflection yoke slit-wound inside a coil bobbin toward its rear end. SOLUTION: In this deflection yoke wherein a front crossover retaining part 38a is composed of ribs on the inside surface of a coil bobbin 30, a flange part 39a at the front end part thereof and locking claws 40a opposite to the flange part, a part of the coil bobbin where the front crossover retaining part 38a is composed is formed into a shape recessed toward its rear end.

In order to correct the phase difference, a correction value Aco is increased or decreased, and phase synchronization of both of the voltages and an inverter output current (i) is obtained.

Title: Positive plate for pasted lead storage battery
Inventor: TOKUNAGA AKIO
IPC: H01M4/57
Filed: 1984-05-23
Abstract: PURPOSE:To suppress the capacity degradation of a positive plate for a pasted lead storage battery caused by its repeated charge-and-discharge by making the positive plate by packing a grid with a paste containing anisotropic graphite and having a density of 3.0-4.0g/cm<3>. CONSTITUTION:A lead powder containing 25% of metallic lead is mixed with 0.5wt% of anisotropic graphite with particle diameters of 200-1,200mum. The thus prepared mixture is then kneaded with dilute sulfuric acid to prepare a positive paste with a density of 3.0-4.0g/cm<3>. After the positive paste is packed into a grid to make a positive plate, a pasted lead storage battery is constituted using the positive plate. As a result, during charging of the battery the anisotropic graphite contained in the positive paste undergoes anodic oxidation to form an interlayer compound which then expands and presses the plate group. Moreover, the good conductivity of the interlayer compound prevents any decrease in the mutual conductivity of the active material particles. Accordingly it is possible to reduce the incidence of capacity degradation even when the density of the paste is low.

Abstract: PROBLEM TO BE SOLVED: To reduce voltage fluctuation during start and reduce the cost by providing a soft circuit capable of starting in such a manner that a capacitor absorbs voltage fluctuation to the power supply line of a driver section and the peak current value of rush current during start does nor exceed the limit value of current. SOLUTION: A capacitor 7 is inserted in a driver section B for absorbing a great, steep voltage fluctuation which occurs during the start of a brushless motor A. And a soft circuit 8 restricts the start of a brushless motor A so as to make the peak current value of a rush current during start is limited less than the current limit value. By doing this, the voltage fluctuation during the start of brushless motor A decreases. Also, a switching power element 2 having a small maximum rated voltage value can be used, cost can be reduced and reliability can be enhanced.
