Title: Multi-beam positioning controller
Inventor: MIZUKAMI MAKOTO
IPC: G11B7/14
Filed: 1993-02-02
Abstract: PURPOSE:To improve the total positioning accuracy of respective light beams by offsetting a translation error signal so as to make the absolute values of selected position error signals equal to each other and their codes different. CONSTITUTION:The amount of geometric off-track becomes maximum on a #2 light beam nearest the center of a beam row and the light beam having the amount of off-track larger than those of two light beams at both ends of the beam row is selected on the basis of the #2 light beam. The position error signal thus selected becomes a second position error signal and further an offset signal is generated by halving the difference value. The offset signal is added to the sum signal of the first and a third position error signals. Then, the amount of off-track of the light beam having the larger offset among #1 and #3 light beams at both ends of the beam row on the basis of the #2 beam coincides with that of the #2 light beam. Since the beam row is controlled so as to reverse the direction of offsets, the off-track is eliminated positioning accuracy is improved.

Title: Measuring method for hydrogen-ion concentration
Inventor: HAMAMOTO OSAMU
IPC: G01N27/416
Filed: 1979-02-15
Abstract: PURPOSE: To take a correct measurement of pH without any need to calibrate an electrode by measuring a potential at a specific point where an electrolyzed substance is electrolyzed in a potential-current curve of electrode reaction in which H +  participates, and then by using a checking line showing the relation between this potential and H +  concentration.  
     CONSTITUTION: For example, balancing electrode voltage E shows pH dependency in terms of oxidation of NO 2   -  as shown by the formula and then this oxidation is carried out under a condition where a diffused rate determining wave is easily shown, the half-wave potential of an oxidation wave to be observed is 0.36V with pH 8 and 0.24V with pH 10, a hydrogen electrode potential standard. As for a solution having a linear relation between the pH and electrode potential, the half- wave potential of an electrolyzing oxidation wave of ions is found and a temperature correction is made to find the pH of the solution. In this method, the pH measurement becomes possible by using a platinum electrode with a small overvoltage, even as to reaction attended on a relatively-large overvoltage such as general hydrogen generation reaction and oxygen generation reaction.

Title: Object detection apparatus
Inventor: NAKANO MASAHIRO
IPC: E03D5/10
Filed: 1994-02-09
Abstract: PURPOSE:To provide an object detection apparatus in which an object can be detected precisely even when disturbance light is generated by any cause and whose power consumption is low. CONSTITUTION:A band-pass filter 26 uses the modulation frequency of a light- emitting instruction signal F as a central frequency, and its output signal is integrated and waveform-shaped by a waveform shaping circuit 27. As a result, even when a photodetector 6b receives disturbance light and outputs a detection signal, the detection signal is blocked by the band-pass filter 26, and no signal is input to an input port P1 for a microcomputer 22. When no signal is input to an input port P2 (in a normal state), a light-emitting element 6 emits light only once according to the light-emitting-instruction signal F at one pulse. Then, when a signal is input to the input port P2 (when a user appears or when disturbance light is generated), the light-emitting element 6 emits light continuously eight times according to the light-emitting-instruction signal F, at eight pulses, which has been modulated at a next detection timing.

Abstract: PURPOSE:To obtain a light pulse tester with a small phasing noise on a back scattering waveform by allowing a signal generation means which generates a test signal light and a local signal light to have a light source and an optical fiber which is connected to the light source and a fluctuation-giving means. CONSTITUTION:The temperature of a semiconductor laser 14 is changed by a light frequency control part 16 and at the same time vibration of a vibration generator 20 is given to an optical fiber 15 for narrowing line width, thus generating a test signal light a where light frequency changes at each specified cycle and a local signal b. The test signal light a is turned into pulses and is applied to an optical fiber 5 to be tested, thus enabling a reflection light from the optical fiber 5 to be tested, a backscattering light c, and the local signal light b to be combined by an optical multiplier 6, and then a beat signal light d to be generated. The beat signal light d is converted to an electrical signal and is subjected to addition processing and then the backscattering light waveform is displayed on a CRT 11. When the phasing noise on the backscattering light waveform is reduced and there are a connection part or a part where light loss changes halfway through the optical fiber 5 to be tested, it is judged to be a step on the rear scattering waveform.

Title: Semiconductor circuit
Inventor: KOBAYASHI SATORU
IPC: H03K19/096
Filed: 1980-02-13
Abstract: PURPOSE:To maintain a prescribed output level for a long period by holding the gate potential of output TR of a bootstrap circuit, which increases the storage level of an MOSIC memory up to the power source level, to a constant potential in terms of direct current. CONSTITUTION:As clock phi1 rises, the potential at point 1 also rises and charging capacity CB starts. At this time, inverter I operates to turn off TRQ5, and consequently phiout rises up to VDD through the conduction of TRQ4 and the boostrap effect of capacity CB. Next, clock phi4 rises and TRQ7 turns on, so that the potential at point 1 will drop. Then, clock phi3 rises and, therefore, phiout rises above VDD. Further, the potential at point 4 exceeds VDD through the effect of the parasitic capacity of TRQ7, which gets unsaturated, so that the potential at point 1 will be held at the power source level in terms of direct current. Thus, a reverse current due to TRQ4 is prevented and a prescribed potential level is maintained for a long period.
