Title: Noise removing circuit of distance measuring apparatus
Inventor: KOSAKA TATSU
IPC: G01S17/08
Filed: 1987-03-16
Abstract: PURPOSE:To enhance an S/N ratio without lowering detection efficiency, by switching LPF in synchronous relation to the light-ON or light-OFF of a light emitting element. CONSTITUTION:The clock CLK of an oscillation circuit 6 is supplied to a light emitting circuit 5 and a synchronous detection circuit 4 and clocks CRL reverse in polarity to each other are supplied to voltage follower amplifiers 11, 12 to operate both of them so that one of them is turned ON while the other is turned OFF. That is, when CLK is an H-level, the amplifier 11 becomes an OFF-state and the amplifier 12 becomes an ON-state and a condenser 9 becomes floating in such a state that the previous charge is accumulated and becomes regardless of the output of LPF. The other condenser 10 forms LPF along with a resistor 8 to attenuate high frequency noise. When CLK is at an L-level, the amplifier 11 is turned ON and the amplifier 12 is turned OFF and the condenser 10 becomes floating in such a state that the previous charge is accumulated to become regardless of the output of LPF. Since the other condenser 9 forms LPF along with the resistor 8 to attenuate high frequency noise, the output of a filter circuit 7 generates no phase shift or deterioration of detection efficiency and high frequency noise can be removed.

Title: Semiconductor photodetector
Inventor: MOTAI HIROYASU
IPC: H01L31/10
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To reduce parasitic capacitance except a light receiving part, i.e., a pn junction, by providing a first electrode formed on an insulation layer while being connected with a first impurity diffusion region through an opening of the insulation layer, and a second electrode formed in a region where the first electrode and the insulation layer of the second electrode are not formed. SOLUTION: A pn junction is formed, beneath a p-side electrode 108, of a diffusion layer 106 electrically independent from a light receiving part, i.e., a diffusion region 105. Consequently, the capacitance at the p-side electrode 108 of a semiconductor photodetector comprises the series connection of capacitance at two parts, i.e., the capacitance between an insulation layer 107 and the optical guide layer 104 in the diffusion region 105, and the capacitance of a depletion layer formed by the built-in potential at the pn junction between the diffusion region 105 and an optical guide layer 102. Consequently, the capacitance at the p-side electrode 108 is represented by the reciprocal of the sum of reciprocal of capacitance at these two parts and the capacitance can be reduced as compared with that of conventional structure.

Abstract: PURPOSE:To improve the soluble efficiency of carbon dioxide gas to a stabilizing solution and the utilizing efficiency of the carbon dioxide gas by solving the carbon dioxide gas to a part of the stabilizer under applying a pressure, and then, mixing it to an untreated stabilizer under the pressure reducing condition so as to regenerate a stabilizer. CONSTITUTION:A stabilizing solution 3 is fed to a trench 2 from a circulation jar 1 through a stabilizer feeding passage 5, and the stabilizer 3 is recirculated to the circulation jar 1 through a stabilizer passage 7. In this case, a part of the stabilizer 3 is delivered to a carbon dioxide pressure-solving device 10 to pressure-solve the carbon dioxide gas, and then an untreated stabilizer 3 is mixed thereto under the pressure reducing condition to regenerate a stabilizer 3. By mixing the stabilizer 3 and the carbon dioxide gas under the pressure reducing condition in this case, the carbon dioxide gas of the larger amount than in the atmospheric pressure is solved in the stabilizer 3. And by making the stabilizer 3 in a pressure reducing condition, an oversatulated condition is generated, and the carbon dioxide gas exceeding the soluble degree is made into minute bubbles and separated. By mixing an untreated stabilizer 3 in such a condition, the gas-liquid contact efficiency is increased, and the carbon dioxide gas is solved in the untreated stabilizer efficiently.

CONSTITUTION:Main waveguides 12-12'' consisting of a Ti diffusion layer, the first crossing waveguides 13, 13' and the second crossing waveguides 14, 14' are formed on an LiNbO3 substrate 11. As for lights of a TM mode and a TE mode, which have been made incident from the main waveguide 12, the TE mode light turns and travels to the waveguide 13' at a crossing point 15 with the first crossing waveguides 13, 13', and the TM mode light travels straight and travels to the main waveguide 12'. In this case, a part of the TE mode light leaks into the main waveguide 12'. At a crossing point 16 with the second crossing waveguides 14, 14', the TM mode light travels straight to the main waveguide 12'', but the TE mode light which has leaked in turns and travels to the waveguide 14', and the leak-in quantity to the main waveguide 12'' becomes extremely small. In case when lights of 2 wavelengths are made to branch, it is executed in the same way. Accordingly, the mode separating and branching functions are elevated.

Title: Method of operating liquid fuel cell
Inventor: NOMURA YOUICHI
IPC: H01M8/04
Filed: 1984-03-28
Abstract: PURPOSE:To directly detect reduction of the fuel concentration for supplying proper amount of fuel independently of the temperature of a cell, by providing two sets of fuel concentration detecting cells, and constant-voltage operating the fuel concentration detecting cells each on a set voltage different from each other so as to detect the ratio of output currents thereof. CONSTITUTION:According to the current/voltage characteristic of a liquid fuel cell body, the output voltage is abruptly lowered where the current density is high if the fuel is short, while where the current density is low an approximately similar output voltage can be obtained independently of the amount of the fuel. When the output current (ia) of a fuel concentration detecting cell (a) operated on a constant voltage of high unit cell voltage Va is compared with the output current (ib) of a fuel concentration detecting cell (b) operated on a constant voltage of unit cell voltage Vb which is lower than the unit cell voltage rated for the liquid fuel cell body, the shortage of the fuel can be detected because the ratio of ib/ia is reduced abruptly if the fuel concentration becomes low. Since the liquid fuel cell body is operated on such an occasion at a current density corresponding to a set voltage higher than Vb, the poles will not be reversed by the shortage of the fuel.
