Title: Planar heat pipe
Inventor: KATO SHUICHIRO
IPC: F28D15/02
Filed: 1985-11-25
Abstract: PURPOSE:To enable increasing of a heat transfer capacitance without generating a heat transfer resistance by forming integrally by an aluminum extrusion die material a planar sheet part to which a heating element such as a large capacity thyristor or the like is directly fixed and a path part in which a passage for sealing therein a heat medium is provided. CONSTITUTION:Each heat pipe 10 is made by forming of an aluminum extrusion die material a planar sheet part 22 and a path part in which a passage 20 is provided, integrally and aligning bottom surface of the same plane. Further, on both horizontal ends of the heat pipe 10, connecting parts 26 and 28 are formed, and coupled by caulking. Since one heat pipe 10 is provided with four path parts, for example, and the passage 20 for the heat medium is formed in each path part, the heat transfer capacitance of the heat pipe is large. Since the path part 24 and the sheet part 22 are integrally formed and metal structures are continued, the heat resistance is small and the flow of heat from the path part 24 is transmitted rapidly to the sheet part 22. The flow of heat which has been transmitted to the sheet part 22 is transmitted to a thyristor 30 closely attached to the lower surface 25 of the sheet part 22 to cool the thyristor 30.

Title: Power tool
Inventor: SOSHIN KOJI
IPC: B25B23/151
Filed: 1991-10-15
Abstract: PURPOSE:To control the torque of a motor through a constant current control by restraining increase in speed at the time of temperature rise, and automatically changing over control action at the time of thread fastening. CONSTITUTION:A power tool is provided with a constant current driving circuit 4, a constant voltage driving circuit 13 and change-over switches 14, 15 to change over the circuits 4, 13. The constant voltage driving circuit 13 is used during low speed until taking a seat, and the constant current driving circuit 4 is used after taking the seat by severally changing over the change-over switches 14,15. Since the constant voltage driving circuit 13 is used during the low speed, and changed over to the constant current driving circuit 4 at the time of thread fastening, the seat can be safely taken even in the case of the temperature rise of a motor to control impact torque so as to be low.

Title: Power source circuit for electric discharge machining
Inventor: FUTAMURA SHOJI
IPC: B23H1/02
Filed: 1987-10-21
Abstract: PURPOSE:To reduce storage of energy in a discharge gap by turning a main switching means OFF then turning a first switching means arranged in parallel with a series circuit for the discharge gap at the output side and a second switching means arranged in parallel with the discharge gap ON. CONSTITUTION:Upon turning a transistor 3 OFF and stopping supply of discharge voltage, reverse voltage between source and drain of a transistor 4 disappears and forward voltage is applied by the energy stored in the inductance L0 of lead wire, thereby conducting the transistor 4 and suppressing surge. Consequently, output from a buffer 14 is brought to zero and the output resistance of a photo-coupler 15 is increased so as to increase the output voltage from a buffer 17 through a resistor 16 thus conducting a transistor 13 and consuming the energy stored in the discharge circuit as Joule's heat when current I2 flows through a resistor 12 and the like. Since large energy is not stored in a capacitance CG of the discharge gap, machining chips can be discharged easily from the discharge gap, resulting in the improvement of surface roughness.

Abstract: PURPOSE:To prevent slippage by controlling oil pressure inside a hydraulic closed circuit according to the degree of the slippage detected by a slip sensor so that the driving force of a wheel corresponding to the oil pressure is under the limit driving force for slippage of the wheel. CONSTITUTION:A controller 100 detects a slippage of a driving wheel W1 on the bases of the inputs from revolution sensors 61 and 63. According to the slip rate, the solenoid valves 155 and 156 receives the signal from the controller and controlled for duty ratio, whereby opening a clutch valve 5 to a specified degree. So, working oil, for example, inside primary oil passage La increased in pressure due to driving of the driving wheel W1 flows through the clutch valve 5 into a secondary oil passage Lb wherein oil pressure is low, whereby reducing oil pressure inside an oil passage Oa. As a result, driving force of the driving wheel W1 is reduced so that the slippage thereof may be restrained.
