Filed: 1982-06-22
Abstract: PURPOSE:To provide smooth start-up on starting operation and prevent compressing a liquid state gas by providing a spool in such a way that the direction in which said spool is accelerated will allow a bypass hole to open up on starting. CONSTITUTION:A spool 19 is provided in such a way that the direction in which it is accelerated to move on starting will allow a bypass hole 11 to open. Then, part of a refrigerant gas, which is delivered toward the end section of a compressing chamber 6 along the direction of rotation of a rotor 5, flows out during compression toward a suction chamber 9 through a bypass hole 11 which opens in an arbitrary intermediate position near an inlet 10 of the compressing chamber 6, thereby providing smooth start-up of the compressor by reducing the starting torque and decreasing the action of compressing the liquefied refrigerant gas when it remaines in an inlet piping connecting the compressor and the inside of the unit or evaporator.

Title: Field effect transistor circuit
Inventor: KANAZAWA KUNIHIKO
IPC: H03D7/12
Filed: 1985-05-20
Abstract: PURPOSE:To simplify or omit a matching circuit by adopting the constitution of a field effect transistor (TR) circuit so that a feedback circuit is added between a drain of a dual gate FET and the 1st or 2nd gate. CONSTITUTION:A signal inputted to the 1st gate 4 through the matching circuit 9 is mixed with a local oscillation signal inputted to the 2nd gate 5 through the matching circuit 9 at the dual gate FET 2. The added feedback circuit has a filter 11, which passes through an intermediate frequency signal only, then the feedback circuit does not act by the inputted signal and the local oscillation signal and the frequency mixing is attained by the dual gate FET. Thus, the matching circuit at the input side is used without any change and both the signals are matched separately, then good matching is attained and the separation of both the signals is very excellent as a feature of the dual gate FET. Thus, the matching circuit is simplified remarkable or omitted.

Title: Drive circuit for voice coil motor
Inventor: NAKAMURA MASAKAZU
IPC: H02H7/085
Filed: 1990-04-25
Abstract: PURPOSE:To prevent adverse effect onto a recorded data or the like and burning of a coil of a voice coil motor (VCM) by retarding production of a seek end signal for a prescribed time when a detected temperature of the voice coil motor exceeds a prescribed temperature. CONSTITUTION:A VCM 12 driven by a command from a drive circuit 11 and a drive operating temperature detection means 13 detects the temperature of the VCM 12. On the other hand, delay means 10, 15 compare the temperature detected by the drive operating temperature detection means 13 with a pre scribed temperature (allowable temperature) and the production period of an end signal generated at the end of a seek operation from the drive circuit 11 is retarded by a prescribed time more than that at the normal state when no undesired state is caused. Thus, the seek operation is not interrupted even once and continues for a longer period than that at the normal state by the prescribed time, and the temperature rise of the VCM 12 is prevented as desired by the reduction in the frequency of seek during that period. Thus, the preven tion in the temperature rise in the VCM and the ensurance of the utility effi ciency are both realized.
