IPC: H03J5/02
Filed: 1980-08-20
Abstract: PURPOSE:To surely prevent the reception of unnecessary electromagnetic waves, by selecting the upper limit of tuning variable range with a band changeover switch. CONSTITUTION:When a channel selection switch 16 selects the 1st terminal and a band changeover switch 8 is connected to a VHF terminal being a vacant terminal, since the band discrimination signal line is detached from ground, a transistor (TR)6 turns on, a voltage of 30 volts applied to a turning variable resistor 17, and a set voltage at this variable resistor 17 passes through a diode 21 and is outputted as a tuning voltage at an output terminal 26 with impedance conversion at a TR25. Then, when the switch 16 is changed over to the 2nd terminal, since a band changeover switch 9 is connected to a UHF terminal, the TR6 turns off and a voltage almost equal to a voltage adjusted by a variable resistor 34 appears at the emitter of a TR7 and this is applied to a variable resistor 18.

Abstract: PURPOSE:To realize the operation for a long time by replacing the consumed part of a thermion discharge member while maintaining the plasma as it is. CONSTITUTION:After a plasma producing chamber 10 and a vacuum container 18 are evacuated to a vacuum, a reactive gas is fed from a gas feeding pipe 17, and a vacuum of about 1X10<-4>Torr is generated in the chamber 10. Then a microwave is oscillated from a magnetron oscillator 14 to produce the plasma. The microwave is amplified by a cavity resonator 13, and it is fed to the chamber 10 through plural slits. The produced plasma is made in a high density by a cusp magnetic field. The positive plasma mainly in the plasma is drawn out by a drawing-out electrode 5, and after neutrized in a neutrizer 21, it hits to a sample in a sample holder 19 so as to process it. Since a filament or the neutrizer 21 can be replaced without opening the container 18 to the atmosphere, or without stopping the generation of the plasma, in such a way, an ion milling or an ion sputtering can be carried out continuously for a long time, and a continuous operation can be realized.

Title: Socket connector
Inventor: SUEKI ARIO
IPC: H01R9/22
Filed: 1994-05-02
Abstract: PURPOSE:To prevent the positional deviation of a lead portion in the pitch direction by forming a fitting slit projecting from the rear end of a lover stage socket, and providing a soldering portion where the lead portion extends along the surface of a printed wiring board. CONSTITUTION:A lower stage socket contact 6 is held by inserting a main body 12 into a lower stage contact containing chamber 4 of a housing 2 through an opening formed at a back surface. Its engaging piece 16 is engaged with a slit 11. An engaging tongue piece is press-fitted to the inner wall surface of the slit 11, to be thus fixed. The slit 11 restricts the position of a soldering portion 19 continuously connected to the engaging piece 16 serving as a lead portion 17. The connectors are arranged in one row at a predetermined pitch P in such an attitude as to prevent positional deviation toward the pitch direction in the intermediate position of a soldering portion 18 of an upper stage contact 15. If the lead portion 17 is deviated rearward beyond the engaging piece 16, no overlap occurs in the pitch direction, thus preventing formation of a bridge between the engaging piece 16 and the lead portion 17 due to sucking-up of solder.
