Title: Optical signal transmitter
Inventor: KAWAHARA HIDEO
IPC: H04B10/60
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption and to make the size small. SOLUTION: A video signal received by an input terminal 11 is frequency-modulated by a frequency of a carrier with a sufficiently higher than a video signal frequency at an FM modulator 12, current-amplified by a light emission drive circuit 14, converted into an optical element by a light emitting element 15 and the signal is sent to a reception section. The video signal is led to a synchronizing signal detection circuit 13, in which the synchronizing signal only is separated from the received signal and the resulting signal is given to a light emission control circuit 16, where the operation of the light emission drive circuit is stopped for the synchronizing signal period to stop the light emission of the light emitting element.  The optical signal received from a light receiving element 21 is given to an FM demodulator 23 of the reception section, where the video signal is obtained by demodulating the received signal with the carrier frequency used by the FM modulator. The optical signal is led also to a carrier detection circuit 24 and its output changes when no carrier component is detected and a latch circuit 25 holds the voltage and provides an output. Thus, the video signal held in the circuit 25 is obtained from a signal output terminal 26 for a period when no carrier is in existence, that is, only for a period when the light emission of the light emitting element is stopped.

Abstract: PURPOSE:To facilitate the changeover of a cable length by fixing one end of each of a plurality of changeover cords the other ends of which are engaged with a plurality of defined places of a cable in a cable pack to the cable pack and selecting the cord. CONSTITUTION:One end of each of long/short changeover cords 14a, 14b (14a<14b) are fixed to a cable 7 in a pack 2 while connecting the other ends to wire type springs 17a, 17b respectively. The springs 17a, 17b are brought into contact with the pieces 19a, 19b of shafts 20a, 20b. As the shaft 20a is drawn up by electrifying a changeover device 22a, a projecting portion 18a comes off of the piece 19a and the cable 7 is delivered up to the fixed portion of the cord 14a causing the pack 2 to sink by the length 14b. As a changeover devices 22b is electrified, the pack sinks by the length 14b. When a floating portion 1 is separated from the pack 2 without electrifying the changeover devices 22a, 22b, the pieces 10a, 10b are separated from projecting portions 18a, 18b and the pack 2 sinks down to the length of the cable 7. Thereby, the cable length can be accurately changed over.

Title: Gas chromatograph
Inventor: DABITSUDO II KUROUZAA
IPC: G01N30/66
Filed: 1979-10-05
Abstract: PURPOSE: To eliminate the component relating to the gas flow from the output signals and to take out the component relating to the thermal conduction by shifting the phase of the control signals, which are to be impressed upon a synchronous detecting circuit for receiving the detection signals, from the phase of the signals relating to the gas flow by 90 degrees.  
     CONSTITUTION: The carrier gases fed out of a tank 20 are mixed with the sample, which is injected from a sample injecting portion 26, so that they are introduced into one side of a heat conduction cell TC. On the other hand, the reference gases in a tank 42 are introduced through a separating tube 34 into the other end of the cell TC, These two gas flows are made to flow through the cell TC by the control the a gas flow interchanging chamber 56 using the output signals S of an FF 46. The temperature signals of a filament F due to the two gas flows are fed through an operation amplifier 86 from the connection between the resistors R 1  and R 2  constituting a bridge circuit. Since, here, FETs 104, 108 and 118 have their conductivities controlled by the output signals CW of the FF 44 which are out of phase of 90 degrees from the signals S and by an anti CW, the component relating to the gas flow is eliminated, and the output signals of the component relating to the heat conduction can be obtained.

Title: Plasma processing method and plasma processing apparatus
Inventor: MORIYAMA KOUICHIROU
IPC: H01L21/3065
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To generate plasma discharge smoothly automatically using automatic device for stabilization by conducting matching operation of an impedance matching device, and plasma-processing a processed body with the first high frequency power adjusted so that plasma intensity may become a targeted value in processing. SOLUTION: The parameters of the matching/tuning of a matching device 106 are set to be initial values which are values of having conducted impedance matching at the point of stable film formation. By fixing the parameter of the matching device 106, discharge is prevented from being eliminated by failed automatic matching operation, and impedance is also matched just after discharge is generated. It is thus possible to generate discharge smoothly with excellent reproducibility. In a discharge generating stage, a small amount of RF power is applied to a bias rod 109 from an RF oscillator 105. Microwave power is applied into a discharge area 102. If a measured Idc value exceeds a threshold 1, generation of discharge is recognized, thereby increasing microwave effective power.
