IPC: H01L31/108
Filed: 1989-12-08
Abstract: PURPOSE:To improve the high-speed response and conversion efficiency of a Schottky diode by providing electrodes on an erected surface of a semiconductor layer having a projecting shape. CONSTITUTION:A semi-insulative GaAs substrate 1 being used as a substrate, an N<-> type GaAs layer 2 is provided as a semiconductor layer formed on this semi-insulative GaAs substrate 1, and an ohmic electrode 4 in ohmic connection with this N<-> type GaAs layer 2 and a Schottky electrode 5 forming a Schottky junction with the N<-> type GaAs layer 2 are provided. The N<-> type GaAs layer 2 is formed projecting on the surface of the semi-insulative GaAs substrate 1, i.e., in the shape of a stripe, and the ohmic electrode 4 and the Schottky electrode 5 are formed on the erected surface of the stripe, i.e., the lateral side thereof. Since a Schottky photodiode can receive an incident light not through the Schottky electrode 5, according to this constitution, a conversion efficiency can be increased. Since the Schottky electrode 5 can be made thick and also the electrostatic capacity of an element itself is small, in addition, a high-speed response is improved.

Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To highly accurately diagnose the failure of the air flow meter of a diesel engine by making a comparison between a cooling loss calculated on the basis of an intake air flow rate detected with the air flow meter, and a cooling loss target value. SOLUTION: A control unit 7 controls an EGR control solenoid 4 and opens or closes an EGR control valve 3, on the basis of an intake air flow rate or the like detected with an air flow meter 10, thereby controlling an exhaust circulation. On the other hand, the control unit 7 determines that the result detected with the meter 10 is correct, when a cooling loss calculated on the basis of the intake air flow rate detected with the meter 10 corresponds to a target cooling loss. When the cooling loss substantially deviates from the target value, the control unit 7 estimates that an error exists in intake air flow rate data, and determine the failure of the meter 10. According to this construction, the erroneous control of the exhaust circulation due to an erroneous flow rate detection value can be prevented, and the deterioration of exhaust and output functions due to the accuracy drop of the exhaust circulation control can be prevented.

Abstract: PURPOSE:To keep the detection characteristic and improve reliability by setting a difference of thermal expansion coefficients of an element and a support to a value lower than the predetermined value on the occasion of fixing a detection element to a supporting means such as a substrate of a semiconductor radiation detector. CONSTITUTION:A CdTe crystal 10 is used as a radiation detecting element, electrodes 12, 14 are formed at both surfaces of the element and these electrodes are connected and fixed to a substrate 18 with an Ag epoxy layer 16.

Thereby, it becomes a high resistance layer due to disturbance of crystal structure and moreover a voltage applied on carrier collection is lowered, deteriorating the characteristic. Accordingly, deterioration of characteristic can be prevented and reliability can also be assured by using CdTe, glass and alumina, etc., like the detecting element as the substrate 18.

Filed: 1992-11-06
Abstract: PURPOSE:To smoothly remove a broken container by providing the same number of cups for recovering cleaning fluid from filling valves as the number of the filling valves in the circumferential direction of a ring plate and by moving the cups to positions directly under the filling valves and to positions separated from those positions. CONSTITUTION:A ring plate 58 is connected integrally with a filling liquid tank 5 and is located in the upper position to support each cup 21 inward of the control position of adjacent filling valves 7. Further, a cleaning device 18 separates the cup 21 and its drive mechanism 57 from around a gripper 8 and bottle mount 6 and arranges them below the filling liquid tank 5. Thus, when a container 2 on the bottle mount 6 is broken by any reason during a filling operation, the cleaning device 18 is not in the way at the time of removing the broken container from the bottle mount 6 and rotary table 4. Therefore, the removing operation of the broken container can be performed smoothly.
