IPC: H04N5/7826
Filed: 1979-08-28
Abstract: PURPOSE: To decrease the lock-in time up to the phase lock of drum motor at start, by discriminating the number of revolutions of durm with the numbr of revolution discriminator and controlling the drum motor with error voltage after stationary state of number of revolutions.  
     CONSTITUTION: The system is added with the signal selection switch 18 having the moving contact 18a, fixed contact 18b to which the phase error voltage 4 is input, and fixed contact 18c connected to ground, number of revolution discriminating circuit 20 outputting the output signal 21 with the input of the frequency errie voltage 6, and signal selection switch drive circuit 22. The number of revolution discriminator 20 discriminates whether the number of revolutions of the motor 12 is at stationary state or not, and until the number of revolutions reaches the steady state from start, the input of the phase error voltage 6 to the adder 5 is interrupted, and the motor is controlled only with the frequency error voltage obtained at the frequency discriminator 17, the phase error voltage 6 is input to the adder 5 after the number of revolutions reaches the steady state and the motor 12 is controlled with the error voltage. Thus, the lock-in time of the drum motor can be reduced.

Title: Compressor for circulating type refrigerating machine
IPC: H02P6/06
Filed: 1992-03-31
Abstract: PURPOSE:To obtain a constitution, relating to a compressor used in a circulating type refrigerating machine for cooling an infrared sensor, etc., which reduces the pollution of He gas of ultrahigh purity injected into the compressor and ensures high reliability. CONSTITUTION:Three leads from the motor coil 9 in a housing 1 of a compressor are connected to hermetic terminals 13. The phase difference of the induced voltage is detected from the waveform of the induced voltage; after giving a phase shift by an electrical angle required and through subsequent logic conversion, a driving signal is obtained and a motor driver 14 for controlling driving current is connected. No sensor is used to detect the rotor position. Since, as a result, the motor driver can be provided outside the machine without the use of a rotor position-detecting sensor, the pollution of the He gas of ultrahigh purity contained in the machine, which is due to gases evolved from such a sensor or the like, can be reduced. Deterioration in the performance is prevented and the reliability is improved.

Title: Pulse tube refrigerator
Inventor: YUYAMA JUNPEI
IPC: F25B9/00
Filed: 1991-05-15
Abstract: PURPOSE: To obtain a pulse pipe refrigerating machine the performance of which does not drop even when the flow rate is large although the machine requires a large flow rate in order to increase the generated refrigeration quantity per unit flow rate passing through a cold storage tank. CONSTITUTION: A pulse pipe refrigerating machine is provided with a compressor 1, a change-over valve 2, cooling water 9, and tubes 10. A pulse pipe 4 is composed of a multistage pipe which is constituted by successively connecting pipes from a small-diameter pipe to a large-diameter pipe and the diameter of the pipe 4 at its room-temperature end 7 is made smaller than that at its low-temperature end 8. Consequently, the quantity of the gas flowing in the pipe 4 through a cold storage tank 3 for compressing the gas in the pipe 4 can be reduced by reducing the volume of the pipe 4. On the other hand, when the diameter of the pipe 4 at the low-temperature end 8 is made equal to the conventional diameter, the same quantity of refrigeration can be generated, since the gas contributing to the generation of refrigeration accompanying expansion work is the gas which gets in and out the pipe 4 through the low- temperature end 8 when the gas is pushed and withdrawn by means of a piston 11 provided at the room-temperature end 7 of the pipe 4. Namely, the quantity of the generated refrigeration per unit flow rate can be improved.
