Abstract: PURPOSE:To enhance purification efficiency as far as possible by producing a contact aeration tank which is a duplex square cubic body having a common separating wall and a storage tank and stepwise skewering and fixing plural contact plates horizontally at prescribed intervals by an air lift pump. CONSTITUTION:The contact aeration tank 3 and the storage tank 4 are constituted by commonly using the separating plate 2. The multistage horizontal contact plates 5, 6 are skewered and fixed by the air lift pump 7. The contact plate 5 of the uppermost stage comes into tight contact with an inside wall 8 and the contact plate 6 of the 2nd stage is provided with a spacing d from the inside wall 8. The contact plates 6 of the 3rd and subsequent stages are provided alternately with the spacings d.

Abstract: PURPOSE: To obtain a charging/discharging control circuit having a function for interrupting discharging upon abrupt increase of load current by providing a circuit for detecting abrupt increase of voltage at an overcurrent detection terminal and controlling discharging based on a signal received from the circuit. CONSTITUTION: Voltage of a current sense resistor 104 is inputted to an inverter 114 and the output signal therefrom is inputted to a control circuit 116 along with the output from a delay circuit. When the voltage of current sense resistor 104 exceeds the voltage of a voltage reference circuit 106 due to generation of overcurrent but it is lower than the inverted voltage of inverter 114, a switch circuit 103 is turned off with a predetermined time lag. If the voltage of the current sense resistor 104 is higher than the inverted voltage of the inverter 114 upon occurrence of the overcurrent state, the switch circuit 103 is turned off immediately. With such arrangement, the switch circuit 103 is turned off immediately upon occurrence of abnormality in the load regardless of the time lag or the transient characteristics of the circuit.

Title: Semiconductor photodetector, semiconductor photodetector array, and image processing device and method
Inventor: HARA KUNIHIKO
IPC: H01L31/10
Filed: 1994-05-09
Abstract: PURPOSE:To enable voltage fluctuations near zero to less affect a photoelectric conversion section so as to stably set a photodetector to zero in sensitivity by a method wherein a means which restrains a semiconductor photodetector from outputting a current when a control voltage is less than a prescribed value. CONSTITUTION:A semiconductor photodetector is composed of a semi-insulating GaAs 1, a thin oxide film 2 which controls a current outputted from the photodetector, a Schottky electrode 3, a variable voltage source 4, an input light 5, and a photocurrent 6. When a control voltage supplied from the variable voltage source 4 is nearly equal to zero, charge generated by the input light 5 is blocked by the thin oxide film 2, a photocurrent is restrained from flowing. On the other hand, a tunnel phenomenon is induced in the oxide film 2 when a control voltage grows above a certain value, and a photocurrent flows into the Schottky electrode 3, passing through the oxide film 2. Therefore, a photodetector of this constitution can be varied from positive to negative and stably set to zero in sensitivity.
