IPC: G06F1/28
Filed: 1980-07-08
Abstract: PURPOSE:To make an external standard clock of a computer unnecessary, by constituting so that a service interruption time is counted at the time of service interruption of a computer, adding a count value and a service interruption generation time which has been saved in a memory device, after an electric power supply has been returned, and calculating a present time. CONSTITUTION:When an operating electric power supply VS1 from the outside is disconnected due to service interruption, an operating electric power supply switching circuit 210 changes over an operating electric power supply to a battery 208, and an electric power supply VS2 is supplied to each circuit in an interval timer module 23.

Title: Disposal of highly concentrated waste liquid without dilution
Inventor: YASUDA YUUJI
IPC: C02F3/34
Filed: 1980-07-09
Abstract: PURPOSE: To dispose a highly concentrated waste liquid without diluting it or adding any reagents to it in only a few days, by aligning the first nitrification vessel, the first denitrification vessel, the second nitrification vessel and the second denitrification vessel in this order to perform nitrification and denitrification.  
     CONSTITUTION: A highly concentrated waste liquid 1 is nitrified in the first nitrification vessel 3, to remove most of BOD and T-N from the waste liquid. At this time, NH 4 -N is oxidized into NO 2 -N, which, in turn, is converted into N 2 , too. The waste liquid is then denitrified in the first denitrification vessel 8 to remove NO 2 -N. A portion of the primary denitrified liquid 9 obtained in this vessel 8 is cyclically fed to the first nitrification vessel 3, while the remainder is nitrified in the second nitrification vessel 11. At this time, NH 4 -N in the liquid is completely oxidized and removed. Thereafter, the liquid is denitrified in the second denitrification vessel 14, to completely remove NO 2 -N or the like which was formed by oxidation of NH 4 -N in the second nitrification vessel 11.

Abstract: PROBLEM TO BE SOLVED: To prevent Au atom from attaching to a GaAs active layer surface by forming a lower layer electrode alone by etching, using a first insulation film as a mask, covering a board surface with a passivation film and forming an upper layer electrode mainly composed of Au on a lower layer gate. SOLUTION: An n-GaAs active layer 2 is formed on a semi-insulating GaAs board, an opening part is formed and a WSi film 4 is processed to a desired shape as a WSi lower layer gate 4'. Then, an SiO2 spacer film 3 is removed by using hydrofluoric acid water solution. After an SiON passivation film 5 is deposited all over and a surface of the GaAs active layer 2 is covered, an opening part is provided and a source electrode 6 and a drain electrode 7 formed of an AuGe metallic film are formed inside an opening part. Since an Au electrode is formed after the SiO2 spacer film 3 is removed by etching, Au does not stick to a surface of a GaAs active layer surface in an etching process and stability of breakdown strength, etc., can be ensured.

Filed: 1981-06-18
Abstract: PURPOSE:To obtain a dropout detecting circuit having a simple constitution and high reliability, by using a retriggerable monostable multivibrator, a charging/ discharging circuit, etc. CONSTITUTION:A reproduced signal received the modulation of frequency or phase is converted into a pulse through a pulse shaping circuit 1 to trigger a retriggerable multivibrator 2. A transistor forming a charging/discharging circuit 7 along with a capacitor is turned on and off by the vibrator 2. Then the output of the circuit 7 is compared with the reference voitage through a comparator 8. When the output of the circuit 7 is less than the reference voltage, the circuit 8 produces a dropout detecting signal. Thus a logical circuit, a delaying circuit, etc. can be eliminated along with a reduction of the number of elements. As a result, the constitution is simplified for a dropout detecting circuit with enhanced reliability.

Abstract: PURPOSE:To exactly execute the measurement by setting a rotational speed in one rotation to a relational expression of continuous speed and time by bringing a speed fluctuation of a rotating body to Fourier approximation, and converting it to an angle. CONSTITUTION:A laser light from a laser light source 1 is projected to a rotating body 5 as light beams having an angle of phi each other by a semi- transmission mirror 2, and reflecting mirrors 3, 4, 6 and 7. A reflected light from the rotating body 5 is subjected to a Doppler shift, detected by a photodetector 8 and becomes a signal brought to heterodyne detection, and inputted to a pulse counting circuit 10 through a pulse-converting circuit 9. A computer 13 derives a rotational speed from a frequency of this pulse, and sets the rotational speed in one rotation to a relational expression of continuous speed and time by bringing a speed fluctuation in one rotation to Fourier approximation. Subsequently, by converting it to a rotation angle, the measurement of the rotation angle is executed.
