Title: Manufacture of electromagnet core
Inventor: KAKIZOE MASAHIRO
IPC: H01H50/16
Filed: 1981-02-19
Abstract: PURPOSE:To simplify an assembling process, and to decrease the number of parts and the number of processes by laminating and fixing magnetic sheets with split sections and cross-linking sections and forming an air gap for preventing remanence by detaching the cross-linking sections. CONSTITUTION:The magnetic sheet 8 with a U-shaped form has the slit section 10 shaped in the direction crossing a magnetic path, punched holes 11 formed at both sides of the slit section 10 and the cross-linking sections 12 molded outside the punched holes 11.

Title: Abnormal revolution preventive method of body of revolution
Inventor: KOBAYASHI SHIYOUJI
IPC: H02H7/093
Filed: 1978-03-03
Abstract: PURPOSE: To prevent the abnormal revolution of a motor due to abnormal voltage in the case when making a power source, by short-circuiting the output of an amplifier, which must be applied to the motor, when making the power source, by releasing short-circuit by a short-circuit releasing signal and by applying the output to the motor.  
     CONSTITUTION: Voltage at a point A becomes to a high level by applying a short- circuit releasing signal S after making a power source - after a condenser 5 is charged, a transistor 6 is in ON, a relay 8 is energized, its contact 8a is closed while a transistor is in OFF because a portion between a base and an emitter of the transistor 7 is short-circuited by means of the transistor 6, and a contact 9a is opened because a relay 9 is de-energized. Consequently, the voltage of OUT 1  becomes equal to the voltage of OUT 2 , the output of an amplifier 1 is applied to a motor 3 through the contact 8a of a switching circuit 2 and the motor 3 is started. Thus, abnormal output voltage by the unstably action of the amplifier 1 in the case when making the power source is not applied to the motor 3, and the abnormal revolution of the motor in the case when making the power source can be prevented.
