Abstract: PROBLEM TO BE SOLVED: To precisely regulate rotation power by continuous motion by performing switching for resistance load connected to output of a generator using power of a rotation power generator, and regulating it up to a cycle setting the accumulated cycle of rotation power. SOLUTION: Switching is performed for resistance load connected to output of a generator by a comparison circuit for comparing the cyclic signal of the generator and a cyclic reference signal with each other by using power of a rotation power generation source 7 (spiral spring incorporated), and the accumulated cycle of rotation power is regulated to the cycle set by the reference signal. In other words, the generator is constituted of a gear 9, a donut-like permanent magnet 10 and gears 11, 12, and a solenoid coil 13 is inserted between the gears 11, 12. A control circuit 14 is connected to both the ends of the solenoid coil 13, and includes the comparison circuit.  The cyclic signal of the generator and the cyclic reference signal are compared with each other by the comparison circuit, and switching is performed for resistance load (resistance value of solenoid coil 13) connected to the output of the generator.

Title: Magnetic video recording and reproducing device
Inventor: YOSHIOKA ATSUSHI
IPC: G11B5/02
Filed: 1984-12-26
Abstract: PURPOSE:To minimize the effect of the crosstalk by transmitting the C signal of the 1st head, the C signal of the 2nd head, the Y signal of the 1st head and the Y signal of the 2nd head to an outside channel from the most inside channel of a rotary transformer respectively. CONSTITUTION:The C signal which is recorded and reproduced at a C channel of the 1st head is transmitted through the most inside winding channels 4s and 4r. While the C signal which is recorded and reproduced at a C channel of the 1st head is transmitted through winding channels 5s and 5r adjacent to the channels 4s and 4r respectively. Furthermore the Y signal which is recorded and reproduced at a Y channel of the 1st head is transmitted through outside winding channels 6s and 6r. Then the Y signal which is recorded and reproduced at a Y channel of the 2nd head is transmitted through the most outside channels 7s and 7r. In such a way, the signals of Y and C channels of the same head are always transmitted every second winding channel. This can minimize the effect of the crosstalk.

Title: Magnetic guiding system for vehicle
Inventor: SATO SHUN
IPC: G05D1/02
Filed: 1988-10-31
Abstract: PURPOSE:To facilitate the production of a magnetic sensor and the adjustment of attaching of the sensor to a vehicle and to improve the stability of automatic traveling of the vehicle by providing the magnetic sensor to be attached to the vehicle with a single dislocation detecting coil and a magnetic field generating means. CONSTITUTION:A magnetic field generating means 32 on the magnetic sensor 3 attached to the vehicle 1 forms space magnetic flux to be extended in the lateral direction of a magnetic mark 2 from two magnetic poles and converged into the magnetic mark 2 and a part of the space magnetic flux intersects with the single dislocation detecting coil 31. Thereby, the vehicle 1 is dislocated from the center of the magnetic mark 2, and when the magnetic sensor 3 is positioned out of the center of the mark 2, both spatial magnetic flux bands are not formed symmetrically about the center of the mark 2, similarly arranged out of the center and allowed to asymmetrically intersect with each other about the right and left of the coil 31. Thereby the polarity of the coil 31 is inverted and an output variable is changed. Consequently, the traveling state of the vehicle 1 can be detected and the dislocation of the vehicle 1 from the magnetic mark 2 can be corrected.

Title: Non-equilibrium voltage correction apparatus of hall sensor
Inventor: SATOU NAGAMI
IPC: G01R33/06
Filed: 1988-10-31
Abstract: PURPOSE:To easily correct the non-equilibrium voltage of a Hall sensor by forming voltage for setting off the non-equilibrium voltage of the Hall sensor to add and input the same to an amplifier with an output offset controller. CONSTITUTION:The voltage determined by the characteristics of the element resistor between the current terminals (l), (m) of a Hall sensor 1 is divided in positive or negative polarity to be taken out from the voltage dividing terminal (t) of a variable resistor 5. Since the non-equilibrium voltage of the Hall sensor 1 is large in the correlation with the temp. characteristic of the element resistor, voltage for setting off non-equilibrium voltage is taken out by setting the variable resistor 5 to a predetermined value. This voltage is added to the output of the Hall sensor 1 to be inputted to an amplifier 3 to set off the non- equilibrium voltage and the non-equilibrium is corrected. By this method, the non-equilibrium voltage of the Hall sensor is easily corrected only by controlling the variable resistor.
