Title: Rotary shaft of vapor-phase growth apparatus
Inventor: TATEMICHI JUNICHI
IPC: H01L21/205
Filed: 1988-07-18
Abstract: PURPOSE:To remarkably decrease the thermal conduction to the lower shaft of a rotary shaft by dividing a susceptor-supporting rotary shaft into upper shaft and lower shaft and narrowing the contacting area of the shafts as far as possible. CONSTITUTION:A rotary shaft fixed to the center of an upper plate of a susceptor 2 is divided into two shafts comprising an upper shaft 4 and a lower shaft 10. The upper shaft 4 to which high-temperature is directly conducted is made of carbon. The lower shaft 10 is made of a metal such as stainless steel having inferior heat-resistance and excellent machinability, mechanical strength and chemical resistance. The lower shaft 10 is rotatably supported by vacuum bearings 21, 22, etc. The outer rings of the bearings are supported by a housing 7 of a rotary mechanism. Since the carbon used as a material for the upper shaft 4 is a soft material, the upper shaft has preferably simple shape. The lower shaft 10 made of metal can be machined to a complicate shape because the material has excellent strength and machinability. A plurality of radially extended attaching branches 8 are attached to the top of the lower shaft 10 as a substitute for a flange.

Title: Power source circuit for camera
Inventor: SASAKI TOYOJI
IPC: H05B41/30
Filed: 1987-07-17
Abstract: PURPOSE:To reduce the scale of a circuit and to enhance a conventional saving in space by making it possible that a power source circuit uses the part of the circuit to a booster transformer in common. CONSTITUTION:An output from an oscillator 1 which outputs the signal of a specified frequency is boosted and two-phase AC voltages whose phases are different each other are outputted from a boosting circuit 2. The phases of the two-phase AC voltages outputted from the boosting circuit 2 are switched to a phase which gives a progressive wave and a phase which gives a standing wave by a control circuit 6. When the phase of the two-phase AC voltages makes the voltage of the phase which gives the progressive wave outputted, an oscillating wave motor 3 which actuates the mechanism of a camera is driven and also the charging path in a charging circuit 4 for stroboscope is opened. And when the phase of the two-phase AC voltage makes the voltage of the phase which gives the standing wave outputted, the main capacitor 5 of the charging circuit 4 for stroboscope is charged with at least either of the two-phase AC voltages. Thus, the scale of the circuit can be reduced and the saving in space can be enhanced.
