Title: Stabilizer for door glass
Inventor: SUZUKI SHINJI
IPC: B60J1/17
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To constantly press an inner part to a door glass by a proper force, and let it cooperate with an outer part to stably hold the door glass by a proper holding force to sufficiently achieve a stabilizer function by a simple work of tightening a screw without depending on intuition of a worker based on long time experience. SOLUTION: A feed screw part 15 (with a male screw part) for pressing an inner part 14 to a door glass 13 is engaged with a pair of flexible arms 19 for moving it. As the inner part 14 gets in contact with the door glass 13 to form a specified pressing force, a rotation force is further added to the feed screw part 15, so the flexible arms 19 are flexed by collision of threads. The feed screw part 15 is rotated by addition of the rotation force, but the door glass 13 is not pressed by a force greater than the specified pressing force. This means that the inner part 14 is pressed to the door glass 13 by the specified pressing force decided by the rigidity of the flexible arms 19.

Part of the bath water in the space A is purified after passage through the filtration material 22, and flows to the subflow passage 17 after passage through the space B.  The bath water entering a heating/sterilizing tank 16 from the subflow passage 17 is introduced into the sterilizing tank after passage through an inflow passage of a heat exchanger, and is further heated and sterilized with a heater 18 and is then derived into a return pipe 19.

Title: Temperature control unit
Inventor: INUTSUKA TSUNEKI
IPC: G03G15/20
Filed: 1979-06-08
Abstract: PURPOSE: To rapidly detect the disconnection of a thermistor, if it occurs, and prevent the excessive rise of temperature by changing the fixed time for the purpose of delaying the disconnection detection of the temperature detecting element according to the standing time from the time when the heating of the member to be heated is stopped.  
     CONSTITUTION: When an electric power source switch is turned on again after it has been turned off to stop current supply to a heater H21 during temperature controlling, the roller has not yet lowered from the specified temperature and therefore it is sometimes heated further and raise its temperature irrespective of disconnection during the disconnection detection inhibit time by a timer. However, if the switch is turned on again by the electric discharge resistances (R21, R23, R22) of a capacitor C21, the charge is remained in the capacitor C21. Hence, the inhibit time of the disconnection detection becomes short and in case a thermistor TH21 has disconnected, it may be detected rapidly and the excessive rise of temperature may be prevented.
