Title: High voltage rectifier
Inventor: KAWASHIMA SUKEHIRO
IPC: H02M7/10
Filed: 1992-09-25
Abstract: PURPOSE:To control a stable load voltage by improving the response characteristics of control without incorporating overshoot characteristics. CONSTITUTION:A current transformer is provided in a load circuit, and a current measurement signal 104 obtained by measuring load current by the transformer is input to a voltage correcting operator 31A. The operator 31A operates and outputs a voltage varied value responsive to the load current. Output voltage variation signal is added to the output signal of a voltage regulator 33 and input to a gate signal generator 35 thereby controlling with a prefetching voltage variation, and hence a rapid response control system is obtained as compared with a control system for feeding back only the voltage measurement signal. Thus, even if the load current is abruptly increased of decreased, the effect of controlling to stabilize a load voltage and to hold it constant is obtained.

Title: Pulsed laser oscillation device
Inventor: KONO HIROMICHI
IPC: H01S3/097
Filed: 1988-10-14
Abstract: PURPOSE:To magnify a corona discharge current for strengthening the generated UV light by providing a gap between one side of a main electrode and a peeking capacitor. CONSTITUTION:When a switch S is closed, electric charge of a capacitor C1 for charging moves to a peaking capacitor CP to start charging of a peaking capacitor CD; however, due to a provided gap G no current flows to a capacitor CC for corona preionization. Provided that the gap G operates at the peak value of the peaking capacitor CP while C1=CP and CC=CP, the current of the capacitor for corona preionization is in proportion to about 1/(CC.LWS2<1/2>). Accordingly, the current gets {(CP.LS1)/(2CC.LS2)}<1/2> times. In general, both of the peaking capacitor CP and floating inductance LS1 are larger than the capacitor CC for corona preionization and the floating inductance Ls2 by two figures respectively so that the current gets larger by about two figures than in the past and UV light for preionization also gets strong.
