Title: Semiconductor photodetector
Inventor: SHIBA TETSUO
IPC: H01L31/10
Filed: 1989-03-03
Abstract: PURPOSE:To obtain a semiconductor photodetector having response at high speed by reducing a sensitivity component slow in response due to diffusion. CONSTITUTION:When incident light 9 is projected onto the whole surface of a photodetector, components projected onto a light-receiving surface are absorbed in a depletion layer formed in an N<->-InGaAs light absorption layer 2 as a first semiconductor layer, and electron-hole pairs are generated. Since electron-hole pairs generated are attracted to an electric field and transfer, response at high speed is displayed while light projected around the light- receiving surface is absorbed to an N<->-InGaAs layer 4, and does not intruded to the inside. The depletion layer does not reach the N<->-InGaAs layer 4 first in the electron-hole pairs generated in the N<->-InGaAs layer 4 and no electric field is applied, and the transit of carriers is prevented by a band barrier by the difference of forbidden band width generated on the interface of the N<->- InGaAs layer 4 and an N<->-InP layer 3 as a second semiconductor layer secondly. Consequently, the components of slow response by a diffusion are removed. Accordingly, the semiconductor photodetector having response at high speed is acquired.

Title: Compressing and evaporating method for steam
Inventor: TAKADA KAZUHARU
IPC: C02F1/14
Filed: 1981-04-08
Abstract: PURPOSE: To achieve a compressing and evaporating method for steam by solar heat which economizes electric power consumption in desalting of raw material water by combining a titled method with a solar heat collector and specifying the evaporation temp. of the raw material water as well as deaeration and bleeding.  
     CONSTITUTION: The fresh water heated in a solar heat collector 4 evaporates in a heat accumulation tank 7 under reduced pressure. The steam serves as a heating source in a heating tube bundle 16 and returns into the tank 7 after condensation. Here, the evaporation temp. is controlled at 50W80°C and the synergistic effect of the efficiency of solar heat collection and the specific gravity of steam is utilized. On the other hand, the sea water which is raw material water is preheated in a cooling tube bundle 27 and is sprayed to the tube bundle 16 from a feed water spraying device 14, whereby it is heated. The dissolved air is released from a pipe 15 and is accumulated into a partition wall 10. This air ejects through outlets 9 into an evaporation chamber 13 and is heat exchanged in a heat transmitting tube bundle 12. The produced steam is compressed with a compressor 19 and serves as a heating source in the bundle 12. The water condensed by this accumulates in a header 36, and the concd. water accumulates in the bottom of the chamber 13. This water is heat exchanged and cooled in cooling chambers 25, 26 respectively. The uncondensible gases from the pipes 28, 29 are dissolved well in the water in the chambers 25, 26 and therefore no electric power is required for discharging.

IPC: G01R33/389
Filed: 1989-03-07
Abstract: PURPOSE:To suppress the fluctuation of a temperature in an electrostatic field generating means for which a permanent magnet is used as much as possible by covering a member to form a magnetic path for a pair of the permanent magnets, which generate an electrostatic field to be applied to an object to be measured, with a temperature depending type resistance member such as a positive characteristic resistance material(PTC), for example, and applying a direct current constant voltage source to this PTC. CONSTITUTION:The circumferential surface of permanent magnets 1a and 1b and the circumferential surface of magnetic pole pieces 2a and 2b are also covered with a PTC 7. The circumferential surface of a yoke 5 is samely covered with the PTC 7 as well. This PTC is a material, for which conductive metallic grain, for example, carbon grain and silicone rubber as a matrix (interpolating material) are mixed, and the distance between the carbon grain is changed by the shrinking of the matrix due to a temperature change. Then, conductivity is changed. A direct current fixed voltage source 8 is connected between both ends of the PTC cover 7. In this case, the polarity of a voltage to be impressed to the PTC cover 7 is selected so as to be coincident with the magnetic path direction of the permanent magnets 1a and 1b. It is desirable that the relation of magnetic fields to be orthogonal so as to follow a Fleming's rule can be obtained even to the magnetic field caused by the permanent magnets 1a and 1b.

Title: Bias circuit
Inventor: YAGUCHI MASAYUKI
IPC: H03F1/00
Filed: 1981-04-08
Abstract: PURPOSE: To reduce greatly the time during which an amplifier is set in a stable operation, by carrying out the setting of bias with the voltage obtained by dividing the power supply voltage by only a codenser.  
     CONSTITUTION: A resistance Rf is connected between an output terminal and a negative input terminal, and a resistance Rs and a capacitor C 2  are connected in series between the negative input terminal and the earth. Then a capacitor C 1  is connected between the joint of the resistance Rs and the capacitor C 2 . The power supply voltage is divided only by the capacitors C 1  and C 2  to obtain the voltage V 2 . The bias is set with the voltage V 2 , and the voltage V 2  is set equal to the potential V 1  at a joint of bias setting resistances R 1  and R 2 . Thus the voltages V 1  and V 2  has the substantially simultaneous rise when the power supply is applied. The potential difference between V 1  and V 2  is compensated to be set at 0 by the charging current passed through the resistance Rf. As a result, the time during which the amplifier OA has a stable operation can be greatly reduced.
