Title: Power source circuit for highly repetitive pulsed laser
Inventor: TAMAGAWA TORU
IPC: H01S3/0971
Filed: 1987-03-19
Abstract: PURPOSE:To provide excellent performance of highly repetitiveness and to reduce the duty of a switch by connecting two sets of reverse capacitors having switches connected in parallel to both ends of a reactor, and alternately closing the switches of each set. CONSTITUTION:A first reverse capacitor C1 is provided between a charging power source B and one end of the low voltage winding of a pulse transformer Tr, and a first switch SW1 is connected in parallel with the capacitor C1. A second reverse capacitor C2 is provided between the power source B and the other end of the winding of the transformer Tr, and a second switch SW2 is connected in parallel with the capacitor C2. That is, the first and second capacitors are connected in series with the low voltage winding of the transformer Tr. Accordingly, the switches SW1, SW2 are sequentially opened and closed to supply normal and reverse currents in the reactor. Thus, the reactor can be reset while the voltage of the switch circuit is reduced and the duty of the switch is decreased.

Title: Method and apparatus for determining quality of cutting tool
Inventor: HARA KAZU
IPC: B23Q17/09
Filed: 1980-05-14
Abstract: PURPOSE: To automatically determine the quality of a cutting tool by raising a warning signal when the integral value of signals obtained from the vibration of the  cutting tool reaches a given level within a specific time.  
     CONSTITUTION: The output of a detector 1 for checking for the vibration of a cutting tool is amplified with an amplifier 2 and inputted to an integrator 3. The integral value of vibration signals integrated during a preset period of time is compared with the reference voltage set with a reference voltage source 5 by means of a comparator 4.
