Abstract: PURPOSE:To attain a control with a small electric current and excellent response at the time of non-operating of a power amplifier by making use of an output from a switching circuit which operates respectively at times when the power amplifier of a headphone is operating and when not operating to control the mechanism. CONSTITUTION:If the power amplifier 3 is set in the non-operating status, the headphone 9 is connected to a jack 5, and a switch 10 provided on the ground line of the headphone 9 is turned off, a small current flows through a high resistor 13, and a first switching circuit 8a operates with this small current. Next, during a time when the amplifier 3 operates, the switch 10 is turned off, so that a third switching circuit 11 provided to open the ground terminal 6c of an output jack 5 operates, to turn off a switching transistor 8a and at the same time to operate a second switching transistor 8b. In such a way, during a time when the amplifier 3 does not operate, the mechanism whose current is in small value and the response is quick is operated, hence excessive consumption of battery energy can be prevented.

Filed: 1988-02-23
Abstract: PURPOSE:To improve the accuracy of a pattern made of organic film by etching glass as a mask, which is made by applying liquid glass to the recessed part of the patter and curing it after patterning the resist layer on the organic film. CONSTITUTION:While a substrate to be etched 1 is rotated, a lower layer organic film 2 made of novolak resin and an upper layer resist layer 3 made of DUV resist are applied to the substrate 1 in that order.

The Permalloy film 1 is positioned on this insulating film. The Permalloy film 1 is then subjected to patterning, Electrodes 2, 3, 4 are built, with the same distance between them, on the Permalloy film 1. Application of electricity to the element of this design results in the generation of an ampere magnetic field between the electrodes 2 and 3. The magnetic field thus generated interacts with the high-permeability film 5 for the generation of a bias magnetic field 8. Between the electrodes 3 and 4, in the same way, another bias magnetic field 9 is generated, which runs counter to the bias magnetic field 8.

Abstract: PURPOSE: For preventing thermal deformation and frosting upon cooling, to connect suction and discharge pipe to a heat storage tank, the former through the medium of a pressure adjusting valve, for heat exchange, and to provide first and third solenoid valves in a short circuit pipe furnished in parallel to two heat exchanger sections and a second solenoid valve on an expansion valve.  
     CONSTITUTION: When first and second solenoid valves 16 and 18 are opened, a third solenoid valve 19 is closed, and the change-over of a three-way change-over valve 14 is made to hot gas bypass pipe side, high-temperature, high pressure discharge gas refrigerant passes through a short circuit pipe 17, not through a heat storage tank 7, and absorbs the liquid refrigerant contained in a condenser 2 and a liquid receiver 3 at the connection 15 of an ejector. Thus-obtained gas-liquid mixture starts defrosting after flowing in an evaporator 5. When said first solenoid valve 16 is closed immediately before melted water becomes water vapour, high-temperature discharge gas refrigerant is lowered to a medium temperature through heat exchange to perform defrosting after flowing in said evaporator 5. Since final defrosting is performed after said high- temperature gas refrigerant is lowered to a medium temperature, the generation of water vapour due to excess heat and frosting upon re-cooling can be preventrd.
