Title: Gas laser unit
Inventor: KATAGIRI SHIYUUHEI
IPC: H01S3/097
Filed: 1978-05-06
Abstract: PURPOSE:To prolong the lifetime of a laser unit and to improve low-noise reliability by closely arranging a conductor near a cathode part via a tube wall and by making it equal in potential to an enclosure containing the tube. CONSTITUTION:A conductor is arranged near cathode 23 of gas laser tube 11. For example, holder 14, made of the conductor, serving as metal fittings to enclosure 13 and laser tube 11 are fitted to enclosure 13. As a result, holder 11 becomes equal in potential to enclosure 13. As this conductor is placed at the higher-current- density part of the cathode part, more effect is obtained while it should not project from the cathode part. In the above constitution, stable discharge is carried out even in a current region where discharge is stopped or becomes unstable in a normal state, so that a low-current drive will be possible. Therefore, the lifetime of the gas laser unit is prolonged and low-noise reliability can also be improved.

Title: Power supply control device of load transformer
Inventor: MATSUO TAKAYOSHI
IPC: H02J3/00
Filed: 1979-04-27
Abstract: PURPOSE: Not only to prevent a trip level of an inverter from heightening unnecessarily but also to make a device small-sized, by lowering a detecting level of an excitation rush current which flows in a load transformer.  
     CONSTITUTION: In case there is a filter consisting of a reactor 3 and a capacitor 4 in the DC side of a rectifier 2, a current flows little from the AC power supply side 1 when a breaker is open, but since the capacitor 4 is charged with a DC current Id which has flowed in the reactor 3, if the breaker 8 is put to work in such a state, a current from the capacitor 4 flows as an excitation rush current depending upon its making phase. A detecting circuit 18 of the excitation rush current outputs a phase suppressing signal of an inverter 5 to a phase control circuit 13 and suppresses the excitation rush current, when both an overcurrent detector 15 and a current detector 17 provide output signals.

Title: Wheel speed arithmetic operating method
Inventor: WATANABE HIDEO
IPC: G01P3/489
Filed: 1987-03-10
Abstract: PURPOSE:To improve the response of arithmetic operation by calculating current wheel speed from the time difference between current calculation time and the time of an edge having the same polarity in a time pair and the number of pulses generated within the time difference. CONSTITUTION:When the edge of the current calculation time has the same polarity with the edge of last calculation time, the wheel speed can be computed from the time difference between both calculation time values and the number of pulses. When the edge of the current calculation time has the opposite polarity from the edge of the last calculation time, on the other hand, the edge of a last calculation time which is a half pulse precedent is utilized. The edge is led or trailed, so time having the same polarity in a time pair of TD and TU stored as to the last arithmetic time is used in either case to perform current arithmetic operation.
