Patent JP-H06294766-A (JP)
Title: Galvanic cell type gas sensor
Inventor: HITOMI SHUJI
IPC: G01N27/404
Filed: 1993-04-09
Abstract: PURPOSE:To locally release the contact pressure of a diaphragm and a working electrode to always refresh an electrolyte on the surface of the working electrode, to reduce the effect of a carbonic acid gas and also to improve responsiveness by a method wherein a groove making an electrolyte part and a working electrode part communicate with each other is provided in a pressure contact part of a presser cover with the diaphragm. CONSTITUTION:A groove making an electrolyte part 6 and the upper part of a working electrode communicate with each other is provided in the contact surface part of a presser cover 4 provided outside a diaphragm 3. Since a pressure of the contact of the diaphragm 3 with the working electrode 2 is released in a groove part locally by the groove, diffusion of an electrolyte in the diaphragm 3 is facilitated and the electrolyte on the surface of the working electrode 2 is refreshed constantly. Accordingly, the vicinity of the working electrode 2 is prevented from becoming alkaline and it consequently prevents carbonate and others from sticking on the surface of the working electrode 2. Since the groove is not formed in the surface of the working electrode 2, a liquid film on the surface of the working electrode 2 is prevented from becoming thick locally, and responsiveness is prevented from deteriorating as is seen in a usual example.

Abstract: PURPOSE:To simplify remarkably a test and adjustment job by using a control section so as to set automatically each adjusting element based on an incremental/decremental quantity from an initial setting value to adjust each adjusting element to a desired level at the adjustment at site and a data stored in a nonvolatile memory. CONSTITUTION:An initial setting label A corresponding to a variable attenuator 1 is inputted to the specific address of a ROM 7 and the output is inputted to a latch circuit 4a by the control of a microprocessor 6, a corresponding analog switch 3q is operated to hold the attenuation of the variable attenuator 1 to the initial setting level A. On the other hand, a reference signal is applied to the variable attenuator 1 by a reference level and the output level is kept to the reference level by inputting the incremental/decremental quantity (a) from a keyboard 10 while measuring the output level of the variable attenuator 1. In adjusting and testing in this way, the quantity (a) at each variable attenuator 1 of each channel of a channel panel is stored and maintained in a NOV.RAM 8. Thus, the test and adjustment job is saved remarkably.

Title: Optical transmission circuit
Inventor: IWAI TAKANORI
IPC: H04B10/516
Filed: 1995-05-01
Abstract: PURPOSE: To minimize non-linear distortion owing a voltage-light output characteristic by inputting an output from a predistortion electric circuit to a semicoductor field absorption type optical modulator as a modulation signal. CONSTITUTION: The bias voltage of the semiconductor field absorption type optical modulator 18 is set up so as to minimize secondary distortion by the non-linearity of a voltage (V)-light output (L) characteristic of the modulator 18 based upon the V-L characteristic. A signal obtained by adding tertiary distortion generated by the modulation of the modulator 18 based upon a modulation signal and tertiary distortion with a reverse phase to the modulation signal to be inputted to the modulator 18 is inputted from the predistortion electric circuit 17 to the modulator 18 as a modulation signal.

Title: Ringing choke converter
Inventor: SATO MORIO
IPC: H02M3/338
Filed: 1995-03-27
Abstract: PURPOSE: To reduce dispersion of the limit value of an output current with respect to the fluctuation of an input voltage and temperature change by applying the sum voltage of the charging voltage of a capacitor and the drop voltage by a resistor between the base and the emitter of a control transistor, so as to limit the output current. CONSTITUTION: When an output current exceeds a limit current value and an output voltage starts to decrease slightly, a photocoupler light receiving part 21a switches off. The limit current depends upon the way to select the respective values of resistors 17 and 19 and a capacitor 18. When the output voltage starts to decrease, the voltage in the reverse direction generated in a positive feedback winding 11c is also proportionally decreased. Therefore, the time for the sum of the voltages across the respective both ends of the capacitor 18 and the resistor 19 to reach the forward-direction voltage across the base and the emitter of a control transistor 16 becomes short. As a result, the ON period of a switching transistor 12 becomes short, and the output current becomes small by a drop in the output voltage. That is to say, the current is folded back.

Title: Semiconductor optical memory
Inventor: KASAHARA KENICHI
IPC: H01L29/74
Filed: 1987-04-30
Abstract: PURPOSE:To obtain an optical memory having high trigger optical sensitivity by providing functions of receiving a trigger light from a layer thicknesswise direction, i.e., planar direction to start a laser oscillation, and continuing the oscillation even after the light is eliminated. CONSTITUTION:The forbidden band energies Eg=E4=E1 of a p2 layer for an anode and an n1 layer for a cathode are provided. A gate is formed by superposing a first layer of impurity concentration p1 and Eg=E2, a second layer of p11 and E21 and a third layer of n2 and E3, and forming a fourth layer of Eg=E22<E21, E23 in the second layer. In this configuration, a bias voltage is set to V=VX, suitable amount of light is incident and absorbed by the gate. Generated holes are injected to the p1 layer to increase an electron current, an avalanche amplification is generated in the third layer to increase the holes injected from the anode to the gate. An element is turned ON by a trigger light by this positive feedback to perform a laser oscillation. The nearer the VX approaches the breakover voltage VBO, the higher the trigger sensitivity becomes. Since the fourth layer of p12 and E21 is isolated from the third layer of n2 and E3, a high voltage is effectively applied at the time of OFF to prevent the VBO from rising.
