IPC: H02P23/00
Filed: 1978-10-09
Abstract: PURPOSE: To facilitate the control of field currents by sensing the field currents on the rotor side without contact by a photoelectric transducer.  
     CONSTITUTION: A rotor 13 around which a field winding 12 is wound, a secondary winding 14 of a rotating transformer, a rotating rectifier 15, a field current sensor 16, and a photoelectric transducer 17 are installed to a motor shaft 11. When ac power is supplied to a primary winding 18 of the rotating transformer, the secondary induced voltage is generated in the secondary winding 14. The secondary induced voltage is rectified by the rotating rectifier 15, and the rotor 13 is excited by flowing the current through the field winding 12. The field current sensor 16 is connected to the output of the rotating rectifier 15 and senses the field current. The sensed signal is sent to the photoelectric transducer 17, generating the light whose amount corresponds to the field current.

Title: Frequency synthesizer
Inventor: SAITO SHIGEKI
IPC: H03L7/18
Filed: 1987-05-22
Abstract: PURPOSE:To extremely quickly establish a phase synchronization at the time of the reforming of a phase locked loop, and to reduce a frequency fluctuation by controlling a phase difference between the phase of the output signal of a standard oscillator and the output signal of a variable frequency divider to be below a specified value by means of a phase difference detection operation. CONSTITUTION:After the variable frequency divider 2 is reset by giving n1 for the frequency dividing number of it, before the loop is closed, the edge of the output of the standard oscillator 3 is detected, and the reset is released, and an n1-frequency division operation is executed. The phase difference of N-frequency division output phase of the variable frequency divider 2 against the output phase of the standard oscillator 3 is detected by a phase difference detection circuit 7, and n2 is set for the frequency dividing number of the variable frequency divider 2 according to the detected result, and in succession, the operation, similar to the first time, is performed. Besides, afterward, the similar operation is performed, as well until the phase difference between the output phase of the standard oscillator 3 and the output phase of the variable frequency divider 2 becomes smaller than the specified value, and immediately after the final phase difference detection operation, the closed loop is formed. Thus, even if the temperature fluctuation or a voltage fluctuation is produced, the process of the phase locked loop is always extremely quickly established, and the frequency fluctuation is reduced.

IPC: F01L1/245
Filed: 1983-07-06
Abstract: PURPOSE:To positively obtain zero rush by inserting an elastic member in which a gas is sealed, into a low-pressure chamber of a hydraulic rush adjustor and feeding oil rapidly into a high-pressure oil chamber when the adjustor elongates. CONSTITUTION:A plunger 5 is disposed within an adjustor body 2, and a hermetically closed low-pressure oil chamber 9 and a high-pressure oil chamber 10 are formed, both chambers 9 and 10 being communicated with each other through a check vale and a leak passage.
