Filed: 1994-06-20
Abstract: PURPOSE:To obtain a radio equipment enabling an excellent reception without being affected by a secondary distortion characteristic, by generating a test signal at the inside of a radio equipment, generating a nonlinear distortion and controlling a parameter. CONSTITUTION:A distortion detection circuit 15 generates test signals for distortion detection, using the free time of a reception slot, and inputs the test signals in frequency converters 104 and 107. The reception electric field of a prescribed frequency component of the output components of the converters 104 and 107 is measured.

Filed: 1984-07-03
Abstract: PURPOSE:To simplify an operation of the time when editing a tape by controlling a motor of a sound recording and reproducing mechanism in accordance with an operation of a reproduction-only mechanism by a transistor. CONSTITUTION:A collector of a transistor 9 is connected to a plus side of a motor 2, and its base is connected to the earth by a resistance 10 and also connected to a rewinding switch 5 through a resistance 11.

Abstract: PURPOSE:To decrease a signal-to-noise ratio in AM reception by making the final stage of an intermediate-frequency circuit independent for AM-FM exclusive use, in an AM-FM radio receiver which uses ceramics at the initial stage of the intermediate-frequency circuit. CONSTITUTION:A FM intermediate-frequency signal is inputted to input terminal 1, and an AM intermediate-frequency signal to input terminal 2; a power supply connected to a FM high-frequency circuit is led to terminal 3, and that connected to an AM high-frequency circuit is to terminal 4, so that when AM-FM alternation switches S1 and S2 are placed on FM sides, the FM intermediate-frequency signal will be detected by FM detection circuit 5 by way of terminal 1, transistors Q1 and Q3, and transformer T2 before being outputted. With switches S1 and S2 on AM sides, the AM intermediate-frequency signal from terminal 2 is applied to bases of transistors Q3 and Q4 by way of transistor Q1, but transistor Q3 is OFF owing to switch S1, so that no influence of the FM intermediate frequency will be exerted.

Title: Diaphragm of pump
Inventor: MIYAZAKI MASATO
IPC: F16J3/02
Filed: 1983-07-30
Abstract: PURPOSE:To enhance durability of diaphragm and make the construction in a small size by fixing the peripheral part to the pump frame in a position, nearer to the deformation bending point radially outside the diaphragm than the deformation bending point appearing on the peripheral part, when pushing is made at the piston working pressure. CONSTITUTION:When the circular portion 4 protruding spherically in a diaphragm 1 is inverted by the working pressure of a piston, the deformation bending point 3 comes outside the circumference of said circular portion 4 to allow a bending motion of the deformation bending point. Therefore the diaphragm 1 is fixed to the pump frame 2 in its inside in a position outside in the radial direction and nearer said bending point without fixation of the part of deformation bending point 3. Accordingly the movable portion of the periphery 3 of diaphragm 1 is given possibility of free motion to release the diaphragm 1 from unreasonable restraint force. Thus the durability can be enhanced, and the minimum diameter designed easily.

IPC: F02B61/00
Filed: 1981-09-03
Abstract: PURPOSE:To reduce fuel consumption by driving a turbine with waste heat from an engine or steam pressure of cooling water to operate an air conditioning drive source. CONSTITUTION:An engine 1 is driven while a pump 18 is operated to send a medium to a waste heat absorbing coil 15 through a liquid side pipe 17 so that the waste heat is absorbed by said coil 15. Next, after the medium is sent to a turbine 13 through a steam side pipe 16 to drive said turbine 13, it circulates through a condenser 19. Steam pressure in the pipe 16 is detected by a pressure switch 21. When said pressure reaches at least a predetermined value, a two- stage clutch 9 is changed over from a pulley 10 to a pulley 11 to idle the pulley 10 and rotate a compressor 8 through a pulley 14, belt 12 and pulley 11 with the rotation of the turbine 13 and disengage the compressor from an engine 1. Thus, the compressor 8 is driven by utilizing the waste heat of the engine to reduce fuel consumption.

Abstract: PURPOSE:To evade the disadvantage due to the drawdown effect in parison, which is injected in the air and droops, in the flow molding of plastic. CONSTITUTION:A self-fused and closed free lower end is produced at an upstream part Y by cutting a parison 1, which consists of the upstream part Y and a downstream part X or X+Y in the previous time run of blow molding. At the present time run, both the processes of the injection for completing the present time parison and of pre-blowing are started at high injection speed and simultaneously without being torn off the cut upstream part from the die 10 of an injection machine. An example, by heating the upstream part Y with a heater 40, the part Y is utilized as the constituent material of a molded article obtained at the prevent time run. Another example, in which the part Y is heated, the part Y is removed at its lower end from the cavity of a mold 50 as the burr in the present time run. Thus, in the case that the material consisting of engineering plastic, which remarkably develops drawdown effect in parison when injected at a slow speed, or the like is used, the productivity, the yield of material and the quality of molded article are respectively improved as compared with those by the prior art.
