Title: Photoresponsive electrode for determining oxidizing/reducing potential
Inventor: DEIIN HEIFUMAN
IPC: G01N27/30
Filed: 1988-07-11
Abstract: PURPOSE: To analyze a wide range of many types of substances properly by determining the oxidation reduction potential of a liquid electrolyte medium using a field effect device with a light-responding semiconductive electric layer, an insulation layer, and electronic conduction layer. CONSTITUTION: When a piston 32 is operated, a fluid medium 30 to be analyzed is pressed, is passed through a porous pad 12, and contacts an electrical conduction layer 20 of a field effect device, thus resulting in an oxidation reduction potential corresponding to, for example, the concentration of, for example, a reagent to be analyzed of the medium 12. The potential changes the electric field of a surface 46 of a light-responding semiconductive electric layer 16 that is laminated exceeding the layer 20 and an insulation layer 18. Then, when the layer 16 is uniformly subjected to light by an LED 44, a carrier is generated, a photo current is generated, oxidation and reduction potential is determined by a field effect device with a simple configuration where no stray current is generated via the layer 16, and a wide range of various kinds of substance are analyzed properly.

     CONSTITUTION: The position of the ship on the sea is detected by ship position measurer 6, and the water depth in this position is measured by sounding machine 5. The horizontal laser beam from stable laser projector 1 on the land is received by photodetecting device 3 on the ship, and an absolute value is given to the water depth by sounding machine 5 by calculating the receiving height by signal processor 4, and it is stored on memory 7 and is printed by printer 8. The laser beam from laser projector 1 is obtained by irradiating the laser beam onto the stepwise reflector to synthesize laser beams which have the phase inverted mutually and are bright in both sides interposing the center dark part.

Filed: 1993-06-16
Abstract: PURPOSE:To provide a circuit over a wide output dynamic range without generating any distortion in the wide band concerning the voltage/current converting circuit to provide an output current in proportion to the input voltages of bipolarity CONSTITUTION:Voltage/current conversion is performed by a feedback circuit composed of an operational amplifier A, transistors Q1 and Q2 and resistor R. At the time, the transistors Q1 and Q2 are biased by diodes D1 and D2 so as to be turned on at all times. Thus, no distortion is generated inside the band of the operational amplifier A. Further, since the collector currents of the transistors Q1 and Q2 are supplied to a load by current mirrors 1 and 2, an output voltage range can be secured almost fully in a power supply voltage.

Title: Detector for original point position
Inventor: TAKEMOTO AKINOBU
IPC: B25J9/10
Filed: 1985-08-07
Abstract: PURPOSE:To improve the positioning accuracy of an original point by using a counter which counts the output pulses sent from an encoder an original point detecting switch is turned on and a storing circuit for the count value of said counter. CONSTITUTION:The original point matching is carried out in such a system where a motor is driven continuously until an original point detecting switch 12 is turned on to clear a counter 27 for reverse of the motor when the switch 12 is turned on and the motor is stopped when the pulse of the original detecting phase is delivered from an encoder 2. A count value storing circuit 28 stores the count value of the counter 27 obtained when the motor is stopped in the first original point matching mode. Hereafter the count value stored in the circuit 28 is set when the original point matching is through. Thus the original point matching is always through when a fixed counter value is obtained. Furthermore it is possible to obtain approximately the coincidence between a time point when the counter value is equal to 0 and a time point when the switch 12 is turned on. This improves the positioning accuracy of an original point.
