Patent JP-S6212114-A (JP)
Title: Leakage transformer
Inventor: KITAMURA KICHIJI
IPC: H01F27/32
Filed: 1985-07-09
Abstract: PURPOSE:To eliminate pitch shift of terminals, to which ends of copper wires wound around a primary bobbin and secondary one are connected, so as to enable a transformer to be easily inserted into a printed wiring plate, by mounting salient pieces so that a space between the primary bobbin and secondary one can be always kept constant. CONSTITUTION:While a primary bobbin 3 for winding a primary coil and a secondary bobbin 6 for winding a secondary coil are put into an iron core 5 of EE type or EI one, together with housing a shunt iron core 4 between the primary bobbin 3 and secondary one 6, salient pieces 9 are mounted so that a space between the primary bobbin 3 and secondary one 6 can be kept constant, with two of them composed at the side of terminals 7 which are mounted on the primary bobbin 3 and secondary one 6, and with one of them mounted near the central of the back surface and on the said primary bobbin 3. Mounting these salient pieces 9 on the secondary bobbin 6 brings the similar effect. Thus, pitch shift of terminals can be prevented between the printed wiring plate and the transformer, capable of easily inserting the transformer into the printed wiring plate, and therefore man-hours can be decreased, together with preventing disconnection of wires by eliminating the pitch shift.

Abstract: PURPOSE: To provide a typing apparatus adapted for a miniature electronic calculator having small-sized, light weight and high typing speed by utilizing the rotary force of a motor rotating only in one direction through a clutch for type selecting, type hammer driving and paper feeding operations.  
     CONSTITUTION: When a switching plate is moved, a clutch is engaged to allow a drive shaft 13 to rotate, a hammer cam 12 to press a type hammer 11, and to type desired letter. When typing operation is repeated to type as desired number and to complete one line, a magnet 67 is energized to rotate an actuating arm 67a. Accordingly, an engaging arm 65 is hitted up against a spring 71 rotatably to rotate a paper feed command shaft and to accordingly rotate an arm 50 integral with the command shaft. Thus, the pawl 50a engaged with the teeth 44 of an engaging plate 44 is temporarily disengaged from the teeth 44a to cause the clutch 48 to be engaged. Therefore, the paper feeding shaft 37 starts to rotate, and feeds a recording paper 14 at predetermined pitches.

Filed: 1991-06-24
Abstract: PURPOSE:To evaluate the distribution of the two-dimensional superco-nducting characteristic by cooling a conductor to a superconducting state, and measuring the superconductive tunnel current or the gap voltage across a probe part and a sample. CONSTITUTION:A sample W and a probe part 12 are cooled to the superconducting state. Under this state, a tunnel current voltage is applied across the sample and the probe part. Then, the superconductive tunnel current flows between the sample W and the probe part 12. The probe part 12 is made to scan in the X and Y directions. Under this state, a piezoelectric actuator 14Z in the Z axis undergoes feedback control so that the critical current value becomes constant. Then, the two-dimensional data with regard to the critical current of the surface of the sample superconductor W are displayed on a display 18. By the same way, the gap voltage Vg across the sample W and the probe part 12 is measured, and the voltage is used as the feedback amount. The gap voltage Vg has the relationship of the expression (1) with respect to the critical temperature Tc of the sample conductor Therefore, the image expressing the two-dimensional distribution of the critical temperature is obtained. In the expression, T is the measured temperature.

Abstract: PURPOSE:To prevent the breakdown of a discharge tube and to improve the efficiency at the time of high pulse repeat by calculating first pulse voltage, that the making power of the discharge tube becomes fixed, based on second pulse voltage, which is delayed by a specified time from the first pulse voltage and is smaller than the first pulse voltage, and controlling a first pulse generating circuit by the calculation results. CONSTITUTION:A first pulse generating circuit 200 supplies pulse voltage, which generates gas discharge, to a discharge tube. A second pulse generating circuit 300 is provided separately from the first pulse generating circuit 200, and this is delayed by a specified time from first pulse voltage with a delay circuit 15, and second pulse voltage, which is smaller than the first pulse voltage, is supplied to a discharge tube 100. A power calculating circuit 17 calculates the first pulse voltage, that the making power of the discharge tube 100 becomes fixed, based on the second pulse voltage, and controls the first pulse generating circuit 200 by this calculation results. Accordingly, the temperature of the discharge tube can be maintained constant, and relaxation from a lower state to a ground state is accelerated, and the inverted population with the next pulse becomes complete. Hereby, the breakdown of the discharge tube can be prevented, and the efficiency at the time of high repeatation can be improved.
