IPC: A63G9/22
Filed: 1993-03-19
Abstract: PURPOSE:To eliminate need of putting on/off a motor drive switch manually by driving rotation of a motor by oscillating an oscillation part manually, transmitting motion of the oscillation part through interlock mechanism to the motor, and supplying a drive voltage to the motor 7 when an induced electromotive voltage higher than a specified value is generated at the motor. CONSTITUTION:Interlock mechanisms 16, 18 to transmit rotation of a motor 7 for driving an oscillation part 11 having a basket part for a baby, etc., to an oscillation part 11 are installed, and a motor control circuit to supply a drive voltage to the motor 7 when an induced electromotive voltage becomes a specified value or higher, and not to supply the drive voltage to the motor 7 when the induced electromotive voltage becomes lower than the specified value is installed. Operation of oscillating the oscillation part 11 or stopping the oscillation part is thus facilitated. In addition, since a limit switch for changing moving directions of the oscillation part is not required, a structure can be simplified, and because the motor is not energized unnecessarily, electric energy is not wasted uselessly.

Abstract: PURPOSE:To enhance the parallelism of X-rays by a method wherein, while a recessed part formed at a counter-cathode is irradiated with electron rays, the X-rays are generated so that the X-rays whose beam is spread narrowly and whose directivity is good can be obtained. CONSTITUTION:A rotary counter-cathode 2 is turned by a shaft 11; electron rays are generated from an electron gun 1. The electron rays which have been bent by a deflection magnet 7 hit a recessed face 13 at an X-ray generation part 8. The electron rays lose its kinetic energy here and generate X-rays. In addition, slits 5, 6 to make the X-rays in parallel are installed in such a way that they are overlapped one upon another. A mask 3 is installed in front of the composite slits 5, 6. In the mask 3 an absorber 16 of a desired pattern is distributed on one face of an X-ray transmitting material 15.

Filed: 1979-07-09
Abstract: PURPOSE: To remarkably decrease the wear of a pump, by feeding and discharging working liquid and oiled coal to and from one side of the supply chambers and the other side of them of floating pistons.  
     CONSTITUTION: When a compound fuel (hereinafter, called COM), in which oils like heavy oil are mixed to a coarse-grained coal, pulverized coal, etc., is transported, firstly the COM in a storage tank 5 flows passing through a pump 6 and pipe 12 into supply chambers 4a and 4b. This causes floating pistons P 1 , P 2  to be gradually lifted to push out working liquids in sections at the opposite side to the side of a discharge pipe 11. After a completion of filling of the COM into the supply chambers, a valve is opened to pour the working liquid into a chamber 3c by a pump 2 and depress downward a piston P 3 . Then the COM at high pressure is fed to various devices through a pipe 13. Operations of the working liquid feed pump 2 at high pressure and the COM feed pump 6 at relatively low pressure can provide a less wear of the pump capable of supplying the COM at high pressure.
