Title: Turntable drive device
Inventor: TAMURA YOSHIAKI
IPC: H02K7/09
Filed: 1977-12-28
Abstract: PURPOSE: To prevent the turning noises by detecting the length of the gap between an armature core and a rotor to control the current to be supplied to a magnetic winding.  
     CONSTITUTION: If a gap length presetting 28 is preset with a value X 0  and if an output X 1  is generated from a displacement meter B 1 , a differential output is generated by a comparator 29. This differential output is fed to series compensating circuit 32. In accordance with the output in the positive direction, the ratio  of the conductive term of a chopper circuit 21 is controlled through a Schmidt circuit 35 so that the current to be supplied to a DC electromagnet 7 1  is determined by the conductive term. The Schmidt circuit 35 renders the chopper circuit 21 conductive for the positive time. As a result, the current according to the conductive term is fed to the DC electromagnet 7 1  so that this magnet 7 1  generates the attractive force proprtional to the current at that time as the floating force of a rotor 8.

Filed: 1989-06-22
Abstract: PURPOSE:To prevent malfunction due to the inclination of a module when mounted/dismounted on an external device by monitoring at least the voltages of terminals at both end parts of a terminal string, and eliminating the standby state of a main circuit only when both voltages reach regulated voltages. CONSTITUTION:Since voltage detecting terminals 2 and 3 are arranged at both ends of the terminal string 1, another terminals can be surely fitted when both terminals are fitted in an external device side connector 8.

Title: Loop type zigzag capillary heat pipe
Inventor: AKACHI HISATERU
IPC: F28D15/02
Filed: 1994-06-09
Abstract: PURPOSE:To make it possible to enhance the heat transmission efficiency of zigzag small-sized heat pipes by installing a forced circulation flow generation means to a thermal insulating part of a unit capillary or its extended part which constitutes a heat pipe. CONSTITUTION:A forced circulation flow generation means 2-1, which forces a hydraulic liquid to generate a circulation flow, is installed to as an insulated part 1-A of a specified unit metallic capillary 1-1 of groups of unit metal-made capillaries 1-1 which constitute a loop type zigzag capillary 1 or its extended part. A static pressure drops from the inner wall surface of a heat receiving part 1-H of every unit metal small-sized pipe by a forcibly circulated convection flow of the hydraulic liquid. This static pressure drop activates dramatically a nuclear boiling up in the heat receiving part 1-H, thereby increasing the generation of vapor foam dramatically in quantities and volumes. In addition, the convection of the hydraulic fluid facilitates the transfer of generated vapor foam groups directed at a heat discharge part 1-C. This further activates the generation of vapor foams and further activates the nuclear boiling up and the generation of vapor foams in the heat receiving part 1-H as well.
