Title: Vacuum piping of vacuum-chuck wafer holding device
Inventor: MARUMO KOJI
IPC: H01L21/683
Filed: 1990-11-29
Abstract: PURPOSE:To make a pressure difference between a suction pressure and an atmospheric pressure large enough to hold a wafer by sucking by a method wherein vacuum lines are branched off from a vacuum suction line, and throttling valves are provided between the distributor of vacuum-chuck wafer holding devices and valves. CONSTITUTION:The suction line 3 of a pump 1 is connected to a distributor 2, where the line 3 is branched off into four vacuum lines 15, 25, 35, and 45 which communicate with transfer chucks 11, 21, and 31 and a wafer chuck 41 respectively, and throttle valves 14, 24, 34, and 44 are provided to the vacuum lines 15, 25, 35, and 45. Therefore, when a vacuum-chuck wafer holding device holds a wafer by sucking, gas of high pressure can be restrained from flowing into the wafer holding device concerned from other vacuum-chuck wafer holding devices by the throttle valve. By this setup, a pressure difference between a suction pressure and an atmospheric pressure can be set large enough constantly to hold a wafer by sucking, so that a wafer transferring action can be safely carried out.

IPC: G11B27/36
Filed: 1990-11-27
Abstract: PURPOSE:To realize the both functions of an amplifier circuit and a meter circuit with a small number of elements by obtaining the meter signal of a direct current level by utilizing a reference bias generating circuit for generating the reference bias voltage of the amplifier circuit. CONSTITUTION:An amplifier circuit 1 is constituted by connecting the multiple steps of differential amplifiers A. A reference bias generating circuit 2 divides a power supply voltage Vcc to Vcc/2 by resistors R1 and R2, executes the buffering and amplifying of this voltage and supplies this amplified voltage to the circuit 1 as the bias voltage. A current detection circuit 3 detects a current Ia for the circuit 2 to generate the prescribed bias voltage Vcc/2 and this current Ia is outputted by an emitter follower composed of a transistor Q11 and a resistor R4 after being converted to a voltage by a resistor R3. This output is applied to the outside as a meter signal Mout for driving a level meter M. Thus, by utilizing the circuit 2 provided for generating the reference bias voltage Vcc/2 of the circuit 1, the signal Mout can be easily obtained.

Title: Underwater heater
Inventor: YAMAUCHI HIROYASU
IPC: H05B3/14
Filed: 1989-12-15
Abstract: PURPOSE:To prevent element breakage and occurrence of a crack of a heating body by absorbing excessive pressing force by a terminal having elasticity even if intense pressing force is applied to the heating body. CONSTITUTION:A PTC element 3 housed in heat radiating cases 4, 5 is interposed between a flat terminal 1 and an elastic terminal 2 while the flat terminal 1 and the elastic terminal 2 are pressure-welded to electrodes 14 on both faces respectively. On the other hand the flat terminal 1 is electrically insulated from the heat radiating cases 4, 5 by an insulating board 25. Thus at least one of the terminals of a pair of terminals interposing a heating body in the heat radiating case has elasticity against compression. Thus when tightening force or clamping of the heat radiating case is too intense, the excessive pressing force to the heating body can be absorbed by the terminal having elasticity so that occurrence of cracks or element breakage or the like on the heating body can be prevented.

Title: Multi-point optical transmission system
Inventor: SASAI HIROYUKI
IPC: H04B10/564
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a multi-point optical transmission system by which code division multiplex signals from pluralities of slave stations are transmitted to a master station as a multi-point light without deteriorating the C/N regardless of provision of an incoming photoelectric conversion section of the master station. SOLUTION: Radio base stations 101 -10n apply frequency conversion to each code division multiplex signal so that the respective frequencies differ from each of the radio base stations 101 -10n and convert the signal into an optical signal, which is sent to an exchange station 11. The exchange station 11 synthesizes optical signals, applies photoelectric conversion to the signal and extracts each code division multiplex signal from the obtained electric signal. As a result, since each signal going to be demodulated by demodulation sections 1161 -116n includes only the code division multiplex signal from the Radio base stations 101 -10n , other code division multiplex signal not demodulated is not a noise component with respect to the base band digital data obtained through demodulation different from a conventional system.
