Abstract: PURPOSE:To release attraction between a magnetic sheet and a magnetic head when the sheet is stopped and to surely guarantee the succeeding rotation after the stop by providing a resistance heating body on the recessed part of a medium guiding face circularly surrounding the periphery of the head. CONSTITUTION:When the magnetic sheet 1 is rotated, the inside of the recessed part 5 of a head unit 2 is turned to negative pressure, the sheet 1 attracted by the negative pressure comes tightly into contact with the magnetic head 3, so that recording or reproducing operation is executed. In the stopped state of the rotation of the sheet 1, the pressure of air in the recessed part 5 is still negative pressure and the sheet 1 is attracted to the medium guiding face 4, but when a switch 10 is closed in this status, current flows into a printing resistor 7, which is heated. The temperature of the air closed in the recessed part 5 of the unit 2 is increased by the heating, the air pressure is increased together with the rise of the temperature, and when the pressure becomes equal to atmosphere, the sheet 1 is separated from the unit 2 by the elastic recovery force of itself. Thereby, the attraction of the sheet 1 to the head 3 can be released.

Title: Control method for conditional branch instruction
Inventor: YAMAGUCHI SHINICHIRO
IPC: G06F9/28
Filed: 1987-04-02
Abstract: PURPOSE:To shorten the executing time of a conditional branch instruction with no extreme increase of the hardware quantity, by using a circuit which sends a jump signal to an instruction control unit in response to the conditions of the conditional branch instruction and the comparison result of arithmetic statuses. CONSTITUTION:A condition comparator 63 compares a condition register 62 with an arithmetic status 90 in a state where the conditions 120 of a conditional branch instruction are latched by the register 62. When no coincidence is obtained from this comparison, the unsatisfaction of conditions is decided and a signal line 65 is not asserted. Thus no jump signal 100 is outputted from a jump signal generating circuit 66 and the next microinstruction 130 is latched by an instruction register 61. Then the instruction 130 is carried out. When the conditions are satisfied, the line 65 is asserted and the signal 100 is delivered. Thus the pipeline of a data processor is initialized and the operation is started at a fetching action of a jump destination. At the same time, the instruction 130 is invalidated by an invalidating circuit 67.

Title: Switching method for winding in three-phase induction motor
Inventor: NAKAMURA ATSUO
IPC: H02K17/30
Filed: 1993-04-06
Abstract: PURPOSE:To provide a switching method for windings in a three-phase induction motor with a wide-range output characteristic and no fear of dielectric break down caused by induction voltage generated at the winding. CONSTITUTION:A switching method is used to switch each winding in a three- phase induction motor so that constant output characteristics are ensured in a wide range from low speed to high speed. The induction motor has split points divided by a whole-number ratio based on an overall winding number in each winding. The phase winding has each lead wire at its split point so that the winding can be put in a separated state. In a low-speed range, all windings are put in a Y-connection composed of low-speed winding (1L, 2L and 3L). On the other hand, the high-speed windings (1H, 2H and 3H) are put in Y-connection in a high-speed range. The unnecessary windings in the connection out of low-speed windings are separated and insulated electrically or one end is connected to a neutral point (N), while the other end is opened. In this way, the windings are switched in a Y-Y connection method, and three-phase power is supplied to each phase winding.

Title: No-pollution heat engine to drive turbing by solar heat
Inventor: KATAYAMA KIYOUHEI
IPC: F01K9/00
Filed: 1978-07-04
Abstract: PURPOSE: A no-pollution heat engine devised to conduct heated water by solar heat to a low-pressure turbine for obtaining output between the heated water and seawater.  
     CONSTITUTION: When water is introduced into an evacuated condenser, since steam pressure is varied according to the water temperature, pressures can be given differently. When an engine is operated between temperatures of 70 and 30 degrees C. for example, it gives the same result as it is operated between pressures P 1 =242 mmHg and P 2 =31.8mmHg. A heat engine is constructed upon this principle. For example, in a turbine system to obtain the output of 10,000 KW, the roof is constructed into a solar heat collecting tank structure severally divided and evacuated inside. Each tank is connected through a pipe to a low pressure turbine 1, which drives a vacuum pump 2 for keeping a condenser 4 in a fixed vacuum. A water supply pump 3 is connected to the vacuum pump 2 through a clutch.
