Title: Manufacture of magnetron for electronic range
Inventor: KAMISAKA AKIRA
IPC: H01J9/14
Filed: 1984-12-10
Abstract: PURPOSE:To prevent the sealing of a magnetron for an electronic range through pressure welding from being deteriorated even by an intermittent operation of the range over a long time by sealing an expanded portion of an antenna conductor by the pressure welding applied from outside of an exhaust pipe, the expanded portion having the same cross section as the antenna conductor. CONSTITUTION:After assembled,a magnetron is exhausted by an exhauster through a metallic exhaust pipe 31 connected between the magnetron and the exhauster. At the final stage of the exhaust, a pressure welding tool 35 is located in a sealing position T and an expanded portion 34 of an antenna conductor 26 is pressure welded to the inside of the exhaust pipe 31 while the expanded portion 34 is shrunken by the exhaust pipe 31 pressed by the tool 35 in the major direction of the sectional form of expanded portion 34 as shown by arrows F. The position T is so selected that a position where crushing the pipe 31 starts approximately corresponds to the bottom end 34a of the expanded portion 34. Since the metallic contact between the expanded portion 34 and the exhaust pipe 31 begins at a considerably earlier stage in the pressure welding because of a sufficiently large cross section of the expanded portion 34, a large pressure welding force indispensable to an intermetallic cold welding is secured thereby.

Title: Vehicle air-conditioning device
Inventor: DOI SHIGENORI
IPC: B60H1/12
Filed: 1990-09-28
Abstract: PURPOSE:To enhance the confortability and the blur resistance in a vehicle air conditioning system which can change its blow-out mode, by reducing the volume of air to a heating means when the blow-out mode is changed over into a heating/defrosting mode so that the volumes of air blown out from a heating blow-out port and a defrosting blow-out mode are increased. CONSTITUTION:When the blow-out mode is changed over into a heating/ defrosting mode during heating mode operation, the opening degree of an air mixing door 10 for a heater core 9 which has been set in accordance with an ambient temperature is decreased to a position indicated by the broken line from a position indicated by the solid line. With this arrangement, the volume of air fed to the heater core 9 is reduced in order to restrain the temperature around the heads of the passengers from increasing. Simultaneously, the drive voltage of a blower 7 in accordance with the ambient temperature id changed to a driver voltage for the heating and defrosting mode in order to increase the volume of air from the blower so as to compensate for a decrease in heating capacity which is caused by a decrease in the opening degree of the air mixing door 10.

Title: Trespass monitor device
Inventor: SUZUKI OSAMU
IPC: G08B13/183
Filed: 1993-10-19
Abstract: PURPOSE:To eliminate a monitoring disabled area at the part occupied by the trespass monitor device which monitors trespass by sending and receiving an energy wave. CONSTITUTION:A signal body 21 which contains transmitters PT1 and PT2 or receivers PR1 and PR2 sending or receiving energy waves is erected along the outer periphery of a monitor area and trespass is detected from the cutoff of the energy wave between signal bodies 21. This trespass monitor device reflects the energy waves from the transmitters PT1 and PT'' by a reflection body 24 and inputs them to the receivers PR1 and PR2. Therefore, one signal body 21 is made narrow in the angle between the energy waves sent to and received from an adjacent signal body 21, so trespass monitoring can be performed more completely.

Title: Vaporizer structure of heat pump type heater for low temperature water
Inventor: TAKIUCHI KAZUO
IPC: F24H1/00
Filed: 1984-12-11
Abstract: PURPOSE:To improve the vaporizing performance by forming the main body of a vaporizer in a box container in which multiple finned vaporizing pipes are parallelly arranged in which the refrigerant flows from the bottom to the top, and causing low temperature water to flow downward in the direction opposite to that of the refrigerant as it makes a detour. CONSTITUTION:The refrigerant G discharged out of an expansion valve 3 moves upward from the bottom to top in vaporizing pipes 9 through a communicating pipe 10 in a vaporizer 4, while low temperature water C flows downward from a spray pipe 13 as it makes a detour by the effect of a buffle plate. The refrigerant G vaporizes itself by taking heat away from the low temperature water C, and enters into a compressor 1 through a vapor duct 15, while the cooled low temperature water C is discharged from a discharge pipe 14. Such process makes up the vaporizer func tion. Since the downflow of the low temperature water C is opposite to the upward movement of the vaporized refrigerant G, the vaporized refrigerant G, the vaporization becomes efficient. Since the low temperature water flows downward as it makes a detour, the full contact with the vaporizing pipes 9 is ensured. Further, owing to the multiple fins 8, the heat exchanging surface is expanded to improve the vaporizing performance.
