Abstract: PURPOSE:To limit the load of a motor to a certain value or smaller by stopping the rotation of a capstan motor for only a preliminarily determined time in accordance with the number of times of the operation of the capstan motor. CONSTITUTION:When a running instruction signal 10 is inputted to an input port 5, a microprocessor 2 increases the value in a register provided in a RAM3 by one for the purpose of integrating the number of times of input of the running instruction signal 10.

Title: Method of generating by motor without counter electromotive force
Inventor: SHIBUTA MASAKAZU
IPC: H02K53/00
Filed: 1978-08-23
Abstract: PURPOSE: To eliminate the generation of a counter electromotive force at a motor by rotating a conductor perpendicularly to the magnetic flux of the magnetic pole of the motor.  
     CONSTITUTION: When a conductor 2 is surrounded in a space by a conductor 1 to short between the conductors 1 and 2 at the portion P and a current is flown from the conductor 1 at the rotary shaft side, the current will flow through the portion P to the conductor 2. Since the magnetic flux produced by the current flowing through the conductor 2 at this time is surrouned by the conductor 1, it cannot outgo from the conductor 1. Thus, the magnetic flux of the conductor in the moving direction and the rear magnetic flux are always rotated perpendicularly to the magnetic flux of the  magnetic pole at the conductor, and the magnetic fluxes in the moving direction of the conductor and in the rear are common in the circular area. Accordingly, even if the conductoers are rotated, it cannot increase nor decrease the magnetic flux. Thus, it can eliminate the generation of a counter electrmotive force at the motor.

Abstract: PROBLEM TO BE SOLVED: To reduce the storing capacity for storing a map as well as the fuel pressure setting method of an internal combustion engine capable of reducing the time required for a matching test necessary of obtaining an optimum aimed fuel pressure. SOLUTION: At the execution of 'stratified combustion', the fuel combustion time (requiered fuel injection time) where the output torque of engine 11 becomes the maximum is constant irrespective of increase and decrease in the fuel injection amount. By utilizing it, at a matching test for obtaining a necessary fuel injection time at the time of 'stratified combustion', the engine speed is varied sequentially under the conditions where the fuel injection amount is constant, and thereby the necessary fuel injection time is obtained for each engine speed. Then, the obtained necessary fuel injection time is mapped as a primary map of the engine speed, and according to the map, the necessary fuel injection amount is computed bassed on the engine speed.  Further, based on the computed amount, an aimed fuel pressure at the time of 'stratified combustion' is computed by use of a specified calculation expression.
