Title: Ditto
Inventor: OSUBUARUTO FURIIDOMAN
IPC: F16H9/18
Filed: 1990-11-20
Abstract: PURPOSE: To reduce a hydraulic loss output so as to control torque-dependent pressure bonding force by arranging a regulation member between a driving unit and a driven unit inside a torque transmission passage and connecting the regulation member to a pump itself generating a torque-dependent pressure. CONSTITUTION: When torque is kept constant, even a pump 20 discharges only a displacement corresponding to a leakage loss generated in a regulation member and in a supply portion, so that only a slight leakage loss is generated. At the same time, a pressure corresponding to the generated torque is generated in a chain 3 in a pair of pulleys 1, 2 according to the pressure increase inside pressure chambers 9a, 6a. When torque is changed suddenly, a pressure increasing in compliance with the change is formed inside the pressure chambers 9a, 6a, and a displacement discharged by the pump 20 is received by the rigidity or flexibility formed matchingly with the wall of the regulation member. When torque is reduced, a pump casing is rotationally returned by a value obtained by subtracting a value corresponding to a leakage loss.

Title: Radiation electric heater
Inventor: JIYOOJI ANSONII HIGINZU
IPC: F24C7/04
Filed: 1990-11-21
Abstract: PURPOSE: To restrict an entrance of a large initial surge by arranging a resistance means arranged so as to be temporarily inserted in series into its ray source means when an electric current is carried to an infrared ray source means, under a wall. CONSTITUTION: When lamps 22 and 24 are cold, a parallel resistance value of these is about 2Ω for a 1800W heater. However, when these are put at an ordinary operating temperature since an electric current is carried, the parallel resistance value is about 25 to 30Ω. A resistance value of a resistance wire coil 54 is selected as a value close to a resistance value of the lamps, for example, a range of 10 to 30Ω at an operating temperature of these. When an electric current is carried to the lamp 24, a voltage drop in a filament 26 of the lamp 24 is comparatively small, and this voltage is insufficient to actuate a relay 68, and a switch 70 is opened as it is. In this way, the coil 54 is connected in series to the lamps, and restricts an initial surge of an electric current passing through the cold lamp filament 26.  When the filament 26 of the lamp 24 is heated, a resistance value increases, and finally, this voltage reaches a value sufficient to actuate the relay 68, and the switch 70 is closed, and the coil 45 is short- circuited, and the whole source voltage can be directly impressed on the lamps.
