Title: Clamp type current transformer
Inventor: OWASE JIYOUJI
IPC: H01F38/30
Filed: 1980-04-08
Abstract: PURPOSE:To form a magnetic path by a small number of flat plate magnetic materials and miniaturize and lighten a device by a method wherein core materials for forming a closed magnetic circuit are surface-contacted with sufficiently large area as compared to the sectional area of the magnetic flux of magnetic path materials, and the closed magnetic circuit is closed. CONSTITUTION:A separating and contacting section is formed to at least one location of a magnetic closed circuit penetrating a coil, and the contacting area is made large sufficiently as compared to the sectional area of the magnetic flux of the magnetic closed circuit. For example, the both sides 2b, 2c of a flat plate-shaped core 2a penetrating a coil 3 wound on a bobbin 4 are bent in the same direction, and an AC wire A coated with an insulating material is held between the core 2a and can be clamped. The bobbin 4 is covered with an insulator 5, and a lead wire of the coil 3 is connected to terminals 6, 6. The noses 2d, 2e of the core are fixed by means of a clasp 7 so that the contacting area is made large sufficiently as compared to the sectinal area of the core 2. Thus, a magnetic path can be made up by one or a small number of flat plate magnetic materials having high permeability, and a device can be miniaturized and lightened.

Title: Input protective circuit
Inventor: KITAMURA YOICHI
IPC: H01L23/62
Filed: 1989-02-27
Abstract: PURPOSE:To decrease the input protective circuit of an LSI to an irreducible minimum in area so as to obtain the input protective circuit which is excellent in area effect and able to cope with pulses of high energy by a method wherein a thin film varistor is provided just under the input pad of the LSI. CONSTITUTION:A this film varistor 14 of low operating voltage is formed just under an input pad. Therefore, when pulses of a few positive volts or more are applied to the input pin of an LSI, the LSI is able to cope with the pulses making their waveform blunted with the capacitive component of the varistor 14 in the case of high voltage pulses. If high energy pulses are applied, an anomalous voltage is clipped through the rapid reduction of the varistor 14 in resistance owing to its non-ohmic characteristic to protect a diffusion resistive layer and a wiring 17 against burning making a current flow into an Si substrate. By this setup, an effective input protective circuit which is small in occupying area and excellent in pattern efficiency and can cope with pulses of high voltage and high energy can be obtained.

Title: Torque sensor
Inventor: NAGANO EISHIN
IPC: G01L3/10
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To facilitate machining and assembly and to obtain the torque sensor which has small variance in detection characteristics. SOLUTION: When a helm is applied with torque, and an input shaft 2 and an output shaft 3 rotate relatively, a coil spring 9 increases and decreases a twist. Consequently, the pitch of the coil spring 9 varies, so the quantity of the air gap between adjacent windings varies, so that the magnetic resistance of a magnetic circuit composed of detection coils 16 and 17 increases and decreases. The detection coils 16 and 17, therefore, vary in impedance. That is led out as the voltage across the detection coils 16 and 17 to obtain the output corresponding to the torque.

Filed: 1988-02-29
Abstract: PURPOSE:To reduce the waiting time required when a set temperature is changed by rotating a rotary body by receiving a change signal from a 1st set temperature to a 2nd set temperature. CONSTITUTION:When, for example, a development device containing black magnetic toner is set, the black toner is detected and a control unit 11 sets the set temperature of a fixing roller 7 by receiving the detect signal of the toner. When the development counter is replaces with a monochrome development device containing nonmagnetic color toner in such state, the color toner is detected and by receiving the detect signal of the color toner, the control unit 11 changes the set temperature of the roller 9 lower than the that for black toner and turns off the heater 9. At the same time, the unit 11 drives a driving motor 12 which drives the fixing roller 7. Then a pressing roller 8 is rotated following the rotation of the roller 7 and the fixing roller is forcedly cooled. Thus the set temperature of the fixing roller can be changed quickly and the waiting time can be shortened.

Title: Magnetic recorder-reproducer
Inventor: KOGURE TAKUYO
IPC: G11B5/027
Filed: 1978-04-20
Abstract: PURPOSE: To automate compensation of recording current electronically and achieve the stabilization of recording-reproducing characteristics by controlling the compensation quantity of high frequencies by the use of sweep voltage in recording equalization adjustment.  
     CONSTITUTION: When a start switch 33 is turned ON, all the circuits assume adjustment state such as of recording equalization, etc. and the DC voltage from a sweep voltage generating block 34 increases gradually. This voltage causes a DC voltage generating block 35 to supply the DC voltage to the circuit element 38 of a recording compensation circuit 37, by which the impedance of the element 38 is changed. The recording compensation quantity then increases with the rise in the voltage. Hence, the input voltage to a voltage comparator 30 hardly changes at a low frequency f 1  and increases at a high frequency f 2 , at which the output level of the comparator 30 gradually lowers and at the specified level it inverts a Schmitt trigger 31 to complete the adjustmenet, when all the circuits restore ordinary recording-reproducing state and the generator 35 maintains the voltage value of that time.
