Filed: 1986-12-08
Abstract: PURPOSE:To reduce the power consumption for the input of a reference potential by inputting the reference potential at the ineffective period of the input signal and using the reference potential so as to apply comparation during the effective period. CONSTITUTION:When a signal potential Vs is a video signal, the effective picture period and the ineffective period are provided in one horizontal period. Switches 4, 7, 10 are turned on by a clock signal phiP for a prescribed period during the ineffective period to input the reference potential Vr. Moreover, the signal phiP and a clock signal, inverse of phiE turn on a switch 2 to input a signal potential Vs. Moreover, the switch 11 is turned on by using a clock signal phiE' wider in the low potential period than the signal phiE and the output signal is fed to a latch circuit 14 via an inverter amplifier 12. A signal subject to pre-stage hold by amplifiers 12, 13 during the off-period of the switch 11 is fed to a latch circuit 14.

Title: Catalytic combustion device
Inventor: KONAKAWA KATSUZO
IPC: F23C13/00
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To solve the inconvenience that poor combustion is caused due to the shortage of oxygen, which results from the decrease in the oxygen concentration of a closed space, even in a construction in which the interior space, that is a combustion chamber performing catalytic combustion, is completely separated from the interior space that internally contains an intake port of combustion. SOLUTION: An intake part 9 forms an ejector with a nozzle part 10 that is connected with a fuel gas tank 7 and a diffuser 12, and it is constructed of an intake pipe 13 and an exhaust pipe 17, both of which are provided to communicate with outside air. Fuel is ejected by the nozzle part 10 at a high speed. The air that is necessary for combustion is sucked in by the ejector from the intake pipe 13 to a catalytic combustion part 14, and the combustion exhaust gas is exhausted from the exhaust pipe 17. Since both the intake pipe 13 and the exhaust pipe 17 communicate with outside air, outside air is constantly introduced to the catalytic combustion, so that the sufficient amount of oxygen can be constantly secured. Further, the ejector by the fuel gas is used, so there is an effect that allows its non powered state.

Title: Production of composite sintered iron parts
Inventor: TAKAGI TADASHI
IPC: B22F7/06
Filed: 1986-12-09
Abstract: PURPOSE:To enable mass production of composite sintered parts having high airtightness by combining plural green compact members and presintering the members, then pressurizing the green compacts toward the joint surfaces of the two members and subjecting the members to normal sintering and copper infiltration in succession. CONSTITUTION:An outside member 1 and inside member 2 which are the green compacts having a prescribed compaction density are divided and molded by using a powder mixture prepd. by adding copper powder, graphite powder and lubricating agent to iron powder and thereafter, the both are joined to prepare the sintered mechanical iron parts. The parts are subjected to the primary (preliminary) sintering at 700-900 deg.C in order to provide the strength to withstand light pressurization to the fitted members 1, 2, then the green compacts are pressurized toward the joint surfaces of the members 1, 2 under 0.5-2t/cm<2> pressure. An infiltrating material piece consisting of Cu-Co, etc., is imposed on the fitted members 1, 2 and the members are held at an adequate temp. to execute secondary (normal) sintering and copper infiltration simultaneously. The defective joining is thereby averted and the mass production of the composite sintered parts having the high airtightness is thus enabled.

Title: Infrared warm-air heater
Inventor: HARA SHINICHIROU
IPC: F24H3/02
Filed: 1990-10-29
Abstract: PURPOSE:To send warm air directly to the user of a toilet and warm the user effectively by installing at a specified location a far-infrared ray sensor connected to an infrared warm-air heater and designed to supply power thereto when the sensor detects far-infrared radiation emanating from the user. CONSTITUTION:When a person 5 enters a water closet l through the door 3, a far-infrared ray sensor 4 detects far-infrared radiation emanating from the human body and, through a lead wiring 14, the detection automatically causes supply of power to an infrared warm-air heater, which is an infrared lamp 9, provided inside the water closet l. When the user 5 sits on the stool, the heat of the infrared radiation from the infrared lamp 9 is emitted directly upon the user around the neck and thus the heating becomes effective instantly. Since the heating rises to a high temperature if used for a long time, a motor 11 of a fan 10 is actuated by automatic control after an elapse of a certain time so that the temperature of the radiation from the infrared lamp 9 is lowered and warm-air heating at its best can be achieved. When the user 5 goes out through the door 3, the far-infrared ray sensor 4 detects the exit of the user and acts to cut off the power to the infrared warm-air heater 7.

Title: Magnetic head device and magnetic head
Inventor: MATSUZAKI MIKIO
IPC: G11B21/21
Filed: 1989-11-09
Abstract: PURPOSE:To increase a pitch angle and to improve traceability by providing a recessed groove on the air inflow terminal side of a magnetic head on a plane opposite to the air bearing plane of a slider in a direction to cross with the running direction of the air, and setting a load point at a side nearer to an air outflow terminal side than the intermediate part of length of the magnetic head observing in the running direction of the air. CONSTITUTION:Since the load point P2 is set at the side nearer to the air outflow terminal side than the intermediate part P3 of the length in the running direction (a) of the air, the area of the air bearing plane 101 at an air inflow side becomes larger than that of the air bearing plane 101 at the air outflow terminal side setting the load point P2 as reference, and dynamical pressure generated at the air inflow side becomes larger than that generated at an air outflow side. Also, since the magnetic head is provided with the recessed groove 104 formed at the air inflow side of the plane at the side opposite to the air bearing plane 101 in the direction crossing with the running direction of the air, the difference of mass between the air inflow terminal side and the air outflow terminal side setting the load point P2 as reference can be reduced, which reduces a moment of inertia. Thereby, the pitch angle can be increased and the traceability can be improved.
