Title: Ion laser
Inventor: TAKAHASHI NORIO
IPC: H01S3/134
Filed: 1983-10-17
Abstract: PURPOSE:To enable to automatically supply gas adequately to the laser tube according to reduction of gas in the laser tube by a method wherein a timer circuit is provided on the control circuit of the electromagnetic valve. CONSTITUTION:When encapsulated rare gas in an ion laser tube 2 decreases by a gas cleanup action and the anode voltage drops, positive output arises on a comparison amplifier 12. The output actuates an electromagnetic valve driving circuit 15 if a timer circuit 13 has been turned to ON condition, a timer circuit 20 is made to ON for a constant time, an electromagnetic valve 8 is opened for a constant time and gas is supplied. As such a result of gas supply, when the anode voltage boosts, negative output arises on the amplifier 12 and the valve 8 is closed. In this case, if there exists not the circuit 13, gas supply action is made, because the anode voltage is still low during a time just after the titled device has been switched on even though an adequate amount of gas has been encapsulated in the laser tube 2. Such an inconvenience is dissolved by providing the circuit 13, which makes signal to OFF for a constant time after the device has been switched on. Incidentally, the circuit 20 is a timer circuit, which puts the device under ON condition for a constant time for preventing excessive gas supply due to responce speed delay during a time up to a time point when the anode voltage boosts.

Abstract: PURPOSE:To prevent a semiconductor device from being improperly mounted by providing a crystalline tissue different from a bulk near a contact when connecting a terminal led out of sealing resin with a foillike terminal. CONSTITUTION:A burr 2 remains by pressing on an outer terminal 3. The terminal 3 is placed under a bearer 1, a punch 4 is elevationally moved upward and downward to collapse the burr 2.
