Abstract: PURPOSE:To enable heating for the rear seat of an automobile and defrosting on its rear window pane, by providing closers in the coolant passages of a main and an auxiliary indoor heat exchangers of a heat-pump-type air conditioner for the automobile so that the closers can be opened. CONSTITUTION:When a hot water heater 21 cannot be used, as at the starting in very cold weather, heating is effected first by a main indoor heat exchanger 9. A gaseous coolant supplied from a compressor 1 and having high pressure and tempreature flows into the main heat exchanger 9 to give heat to the air in the vehicle chamber. At that time, the coolant is condensed into liquid. The liquid coolant flows into a liquid tank 6 through a check valve 10. The heated air is blown off in front of the driver's seat to heat the vehicle chamber. The high-pressure liquid coolant supplied from the liquid tank 6 is changed into a wet coolant of low temperature and pressure by an expansion valve for heating and absorbs heat from the external air in an outdoor heat exchanger 4 so that the coolant is evaporated into gas of low temperature and pressure and then returns to the compressor 1. After a prescribed time, heating operation is effected by the hot water heater 21. Simultaneously, a coolant passage closer 14 is shut off and another closer 13 is opened to effectuate heating for the rear seat by an auxiliary indoor heat exchanger 12.

IPC: C25B9/17
Filed: 1979-04-09
Abstract: PURPOSE:To enhance the durability of the title pump by connecting porous electrodes extending along the inside and outside of a partition wall heating zone heated to a specified temp. or above to lead wires outside the zone to prevent exfoliation of the electrodes. CONSTITUTION:O2-contg. feed gas 11 is fed into cylindrical solid electrolyte partition wall 1 through flow meter 10. Since the interior of heating zone 15 is being heated to 400 deg.C or above with heater 13, and a DC voltage is being applied between porous electrodes 2, 3, each O2 molecule entering zone 15 accepts an electron on cathode 2 and becomes O2<->, which diffuses into wall 1, reaches anode 3, and returns to each O2 molecule by emitting the electron, and the molecule is released into the air. By repeating this reaction O2 in gas 11 is carried from the system through wall 1, and electrons flow through lead wires 4, 5 via connected portions 6, 7 of electrodes 2, 3 and wires 5, 6. Portions 6, 7 are outside zone 15, so abnormal heat due to heater 13 and the high current density is not applied to portions 6, 7 to prevent exfoliation of electrodes 2, 3 from wall 1 at portions 6, 7.

Title: Method of bending plastic sheet
Inventor: HASHIMOTO TADASHI
IPC: B29C53/84
Filed: 1988-02-25
Abstract: PURPOSE:To realize the accurate and high speed bending of a plastic sheet by a method wherein the plastic sheet is bent and the bent part is heated by supersonic vibration and, after that, cooled so as to heat-treat said bent part. CONSTITUTION:Firstly, bending grooves 12 are made by cold-bending (at 20 deg.C) or by pressing with a die blade, the included angle of which is 90 deg., along folding lines 11 on a plastic sheet 1. By being cold-pressed on a female mold 3 with a male mold 2, the plastic sheet is correctly belt along the apex of a V-shape of each bending groove 12. When supersonic vibration is given to a supersonic vibration horn 21 under the condition that the supersonic vibration horn 21 is fitted from above the plastic sheet to the recessed part 31 of the female after the removal of the male mold 2, the temperatures of bent parts 13 become higher than the softening temperature of the sheet in a vary short time due to the frictional heat developed by supersonic energy, resulting in softening the bent part and making the grooves 12, which are made in advance, shallower through the restoration of the shape of the groove. Concretely, the bent parts 13 are reinforced by the restoration of thickness. Further, when the supersonic vibration is stopped, the temperatures of the bent parts 13 are rapidly cooled down to that of the female mold and of the supersonic vibration horn themselves, resulting in fixing the bent shape.

Filed: 1990-02-23
Abstract: PURPOSE:To prevent necessary information from being leaked by detecting a task being executed at the time of dumping the contents of a memory and adding the relational information of the task to a summary list. CONSTITUTION:The relational information of the task being executed at the time of dumping the contents of the memory is added to the summary list. Namely, in the case of forming the summary list 3 from a dump file 2, an editing program 1 detects a task control block (TCB) whose completion code is other than a normal end value from dump information and extracts information having the prescribed relation with the TCB. When the completion code is the normal end value, an execution request control block (RB) relating to the TCB is retrieved, and at the time of detecting a record inditacting the execution of a prescribed dump program in the RB, the relational information of the TCB is extracted. The extracted information is edited to form the summary list. Thus, data important for retrieving the cause of an abnormal state can be prevented from being leaked from the summary list.
