Title: Simple shower
Inventor: SUGITA MAKOTO
IPC: F24H1/18
Filed: 1989-10-06
Abstract: PURPOSE:To secure the operation of a preventive device of a over-rise of temperature with a simple means and use a low-cost O-ring by mounting a heater on the heater attachment plane with the heater inclined to the plane. CONSTITUTION:A heating part 4a is attached on the opening part formed on the bottom of a tank 2 while a heater 5a is inclined to the heater attachment plane 8 and mounted thereon. This heater part 4a is assembled by being pinched and fixed with a nut 9 after overlapping an O-ring 10, a heater attachment plane 8 and a preventive device of over-rise in temperature 6 on the heater 5a. The water stored in a tank 2 is heated with the heater 5a to become hot water. This hot water convects within the tank 2. When it reaches to the bottom of the tank 2, it moves to the direction of the arrow A in the figure between the heater 5a inclined and attached on the heater attachment plane 8 and the heater attachment plane 8. The water in the tank 2 is uniformly heated and the operation of the preventive device of over-rise in temperature 6 is stable. Besides since the part of the O-ring 10 does not rise to a high temperature, an O-ring formed of general material low in cost can be used.

Title: Ratio circuit
Inventor: ITSUKAICHI MASAKATSU
IPC: H03K19/0944
Filed: 1989-10-04
Abstract: PURPOSE:To decrease a through-current and to quicken the rise of an output by using the drain of a load transistor(TR), the output of a multi-input N- channel NOR and the drain of a control TR as outputs and using the output for the input to a C-MOS inverter. CONSTITUTION:When a voltage slightly higher than a low level is outputted from a voltage generating circuit 10, a load TR 1 is always turned on but not in complete ON state, then the load TR 1 acts like a resistor, a through- current flows and when the gmL of the TR 1 is selected small, the through- current is decreased. A control TR 2 is added, N-channel NORs are all turned off and an output goes to a high level by the load TR 1, then the control TR 2 is turned on, thereby quickening the rise of the output voltage by selecting the gmC of the control TR 2 larger than the gmL. Thus, the through-current of the ratio circuit is decreased to quicken the rise of the output level.

Abstract: PROBLEM TO BE SOLVED: To eliminate wasteful power consumption and to prevent noise from being produced by controlling so that the flow of air may not be generated in a state where the photoreceptor of an electrophotographic device need not be cooled. SOLUTION: When a machine works, an air blower 4 is driven to send the air to the upper part of an electrifying charger 12 through a duct 2, so that the flow of air is always generated in the charger 12 to prevent discharge produced substance by a charger wire 9 from retaining. Then, the surface temperature of the photoreceptor 11 is detected. When the detected value is equal to or above a specified value, an air blower 5 is driven to send the air in the photoreceptor 11 through a duct 3 so as to cool the photoreceptor 11. When the surface temperature of the photoreceptor 11 is equal to or under the specified value due to cooling, the air blower 5 is stopped to stop ventilation into the photoreceptor 11. The surface temperature of the photoreceptor 11 is detected also when the machine is stopped.  When the detected value is equal to or above the specified value, the air is sent to the charger 12 and the photoreceptor 11 by the air blowers 4 and 5 through the ducts 2 and 3, so that the photoreceptor 11 is cooled.

Title: Electrically operated side support controller
Inventor: DOBASHI JOSUKE
IPC: B60N2/02
Filed: 1993-10-19
Abstract: PURPOSE:To prevent an interference with people getting on/off a vehicle by moving a side support to a protruding position when a travel signal is generated upon output of a sitting detection signal and a seat belt wearing detection signal and moving the side support to a non-protruding position when the travel signal is not generated nor the seat belt wearing detection signal. CONSTITUTION:When a crew is seated and wears a seat belt, a controller recognizes signals through a sitting detection means 3 and a seat belt detecting means 4. When a vehicle travels, a travel signal generating means 5 generates a travel signal, so that the controller 7 generates a first command signal based on a sitting detection signal, a seat belt wearing detection signal and the travel signal. Then, the controller raises a side support 23 to move to a protruding position through a side support driving means 2. When the vehicle stops and the crew puts off the seat belt, the controller 7 moves the side supoport 23 to a non-protruding position based on a second command signal.

Inventor: SHIMOJIMA HIROMASA
IPC: H01B12/02
Filed: 1991-09-13
Abstract: PURPOSE:To prevent the degradation of an oxide superconductor due to moisture. CONSTITUTION:A Pb-Si-Cd-Bi-O base glass material, which melts at 600 deg.C or less and vitrifies, is coated on the surface of an oxide superconductive polycrystalline so as to form a vitreous protecting film. Its degradation due to the invasion of moisture can be prevented by the vitreous protecting film, so that the characteristics served by the oxide superconductive polycrystalline can be kept for a long term. And subsequently the quantity of optimum stabilizing materials can be easily selected by varying the ratio of the wire 7 to the wire 8. Whereby, the increase in the critical current density and the decrease in the AC loss can be performed while enhancing the stability and the high strength.
