Title: Lower electrode unit drive mechanism for vacuum bath
Inventor: OKAYAMA TOMOHIKO
IPC: H01L21/68
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To obtain a drive mechanism for a lower electrode unit in which leakage of plasma cam be prevented by a structure wherein a supporting rod is coupled through a play with an actuator and the lower electrode is driven upward by the negative pressure in a vacuum bath and driven downward by means of an actuator. SOLUTION: The threaded part 22a of a cylinder rod 22 is fixed, at the forward end thereof, with a stopper 25 using a nut 26. A nut 23 is screwed over the threaded part 22a while being spaced apart by a predetermined distance from the stopper 25 and a displaceable coupling plate 12 is interposed between the nut 23 and the stopper 25. When a heater base 4 is elevated, an air cylinder 20 is brought into a free state and the heater base 4 is elevated by a negative pressure acting thereon. When the heater base 4 is lowered, the air cylinder 20 is extended and the nut 23 of cylinder rod 22 shifts the play part to abut against the upper surface of the coupling plate 12 thus lowering the coupling plate 12. This structure reduces the contact pressure of the abutting member at the upper limit of the stroke of the lower electrode unit thus eliminating local strain.

Title: Heater for automobile using exhaust heat
Inventor: SATO SHINICHI
IPC: B60H1/20
Filed: 1989-10-23
Abstract: PURPOSE:To prevent any over evaporation of operating fluid by switching an exhaust gas flow passage switching door in the direction for allowing the exhaust gas to flow toward a second exhaust gas flow passage for bypassing a heating unit when temperature of the operating fluid steam sent from the heating unit is increased. CONSTITUTION:Temperature of operating fluid steam sent from a heating unit is detected by a sensor 22. A temperature gradient of the operating fluid steam is computed by a means 23 on the basis of the detecting signal. Furthermore, the detected temperature gradient and the preset standard gradient are compared with each other by a means 24. An exhaust gas flow passage switching door 7 and the partitioning valve 12 of an operating fluid return pipe are respectively controlled by a control unit 25 in response to the compared result. In this case, for example, when the temperature gradient is larger than the standard gradient, the control unit 25 switches the exhaust gas flow passage switching door 7 in the direction for guiding the exhaust gas to flow toward a second exhaust gas flow passage for bypassing the heating unit, and also closes the partitioning valve 12.

Abstract: PURPOSE: To improve sliding characteristics of a ski by providing between a binding belt and a ski top a spacer which is formed larger than the space between the binding belt and the ski top and by supporting the spacer elastically so as to selectively affect an expected load of the ski. CONSTITUTION: At least one of two binding members, namely a toe piece 14 and a heel piece 15, is supported movably in the longitudinal direction of a ski 10. These binding members are bound to each other with a binding belt 20 extending over a ski top 11 and constant in length. A spacer 30 is placed on the ski top 11 between the toe piece 14 and the heel piece 15. In such a ski binding, the spacer 30, in the preparation of sliding without a load by external forces, is larger than the space between the binding belt 20 and the ski top 11, and forms a projection 30a for example. The spacer 30 constitutes itself so that it may elastically support the binding belt 20 and the ski.

Filed: 1985-12-06
Abstract: PURPOSE:To determine with accuracy the frequency characteristic of a light-receiving circuit by a method wherein the difference between frequencies oscillated by two semiconductor laser devices is scanned and the output of the light-receiving circuit is measured while input is being made into the light-receiving circuit of the combination of the optical outputs of the two laser devices. CONSTITUTION:A serrated wave out of a signal source 116 is superimposed on a DC bias current in an electric mixer 127 before it is applied to an upper electrode 104 of a semiconductor laser device 102. The application of a very small current on the semiconductor laser device 102 affects the laser device 102 in its oscillating frequency, which in turn changes the difference between oscillating frequencies of two semiconductor laser devices 101 and 102. In an optical intensity modulator 122, an optical output experiencing fluctuation because of the superimposition signal transmitted by the signal source 116 is subjected to modulation with a voltage signal that is a current from the signal source 116 amplified in an amplifier 123. The optical output is combined in an optical mixer 121 with a constant-intensity optical output yielded by the semiconductor laser device 101, and is inputted into a light-receiving circuit 124. The output of the light-receiving circuit 124 is measured by a spectrum analyzer.

Abstract: PURPOSE:To always reproduce information consisting of plural data elements with high accuracy, by executing an illumination by a liner luminous flux whose width is narrower than width in the direction being orthogonal to the array direction, with respect to plural data elements arrayed in the specific direction. CONSTITUTION:Width in the (y) direction of a linear luminous flux for illuminating an information pattern 2 consisting of a slit train on a rotary disk 1 is made narrower than width in the (y) direction of the information pattern 2.

Title: Single mixer
Inventor: SAKA HIROSHI
IPC: H03D7/18
Filed: 1985-12-09
Abstract: PURPOSE:To realize output impedance matching for an intermediate frequency signal over a wide band and to make the matching independent of the circuit shape at a high frequency signal side by providing an intermediate frequency signal blocking circuit on a main line near a mixer diode in a mixer using a plane circuit, grounding and short-circuiting the other end of the diode and connecting a low pass filter to the said main line. CONSTITUTION:The intermediate frequency signal blocking circuit 19 is a circuit showing a passing characteristic to a high frequency signal and a local oscillation signal and showing an open impedance to an intermediate signal and provided on the main line 12 near a mixer diode 13. Thus, the effect of the circuit at the high frequency signal side connected to a terminal 11 and the circuit provided on the main lie on the output matching state at the intermediate frequency signal is avoided. Since a terminal C of the diode 13 is connected directly to a grounding conductor of the main line 12, the parasitic impedance caused at grounding is decreased and the output impedance matching over a wide intermediate frequency signal band is realized. Further, a matching line 12' acts like a matching circuit element having nearly the same degree of capacitance as a termination open stub of an LPF 16 when viewing the diode 13 from an intermediate frequency signal output terminal 18.
