Title: Reading device of optical digital signal
Inventor: KAIZUKA KUNIYASU
IPC: G06K7/10
Filed: 1983-10-07
Abstract: PURPOSE:To detect more clearly the presence or absence of a pit by projecting light from the oblique side on the surface of a reflector film and detecting only the reflected light given from the pit side wall. CONSTITUTION:Parallel beams A and A' are projected from the oblique side to the surface 2 of reflector film and therefore an angle 2theta formed by a reflected beam B and a reflected beam C given from the surface of a pit side wall 1 increases considerably. In this connection, a photodetector 3 is set in the direction where the beam C is caught. Thus only the beam C is detected since the surface 2 is smooth and has reduction of the irregular reflection. When a recording medium is shifted horizontally, it is possible to catch the reflected beams from all pits despite some difference existing between shapes of walls 1. Only the beam C is detected by making use of the smoothness of the surface 2 and a binary signal is produced by the presence or absence of the beam C. Thus the reading errors of digital signals can be reduced.

Title: Zero adjusting circuit
Inventor: SUZUKI YASUFUMI
IPC: G01D3/028
Filed: 1987-07-29
Abstract: PURPOSE:To generate a voltage for offset correction automatically with a digital means by performing on-off operation with the composite voltage of two voltages sent out of an input amplifier and stopping the counting operation of a counter when the composite output becomes zero. CONSTITUTION:The counted value of a supplied clock is converted by a D/A converter 5 into an analog voltage and a bias adder 7 adds a specific bias voltage VB to the output voltage V to generate a voltage V'C which has both positive and negative polarities crossing the zero level. This is added by the input amplifier 1 to an unadjusted offset voltage VOF and a comparator 2 which is turned on and off with the composite output stops the clock counting operation of the converter 5 when its output of the comparator 2 becomes zero. At this time, the voltage VC which is equal in absolute value to the voltage VOF and opposite in polarity is obtained on the output side of the adder 7. For the purpose, the high resolution of the converter 5 is utilized to obtain the high-accuracy voltage VC for offset correction.

Title: Monitoring device for operation of vacuum switch equipment
Inventor: YAMADA MAMORU
IPC: H01H33/53
Filed: 1990-07-18
Abstract: PURPOSE:To accurately detect the operating position of even such vacuum switch equipment whose operating distance is as little as a few millimeters by fixing to a moveable electrode a light-blocking piece provided with through holes so as to install the piece. CONSTITUTION:Light emitted from a light source 2 is blocked by a light-blocking piece 1 and therefore does not reach an optical sensor 3 but when either of through holes 11,12 coincides with this light passage the light is allowed to reach the optical sensor 3 and is converted into an electric signal and input to a processing portion 4. The hole 11 is provided in a position where it allows the light to pass therethrough when a moveable electrode 102 makes contact with a fixed electrode 101 with vacuum switch equipment being closed, while the hole 12 is provided where it allows the light to pass therethrough when the moveable electrode 102 is stopped in a predetermined position farthest from the fixed contact 101, with the vacuum switch equipment being opened. The processing portion 4 carries out predetermined arithmetic in response to an electric signal input thereto from the optical sensor 3 and outputs the result of the arithmetic to an indicator 41. An operator can thus recognize the contents of the equipment visually and also the accuracy of signals concerning the operating position and operating speed of the moveable electrode is enhanced.
