Title: Manufacture of end-face light-emitting type optical semiconductor device
Inventor: NAKANO KOJI
IPC: G02B5/08
Filed: 1988-07-27
Abstract: PURPOSE:To accurately evaluate an optical output characteristic of a light-emitting element on a wafer by a method wherein an optical output face and an optical reflection face are formed on the wafer so as to be faced by utilizing an end face of an element region. CONSTITUTION:A semiconductor substrate 10 and a P-side ohmic electrode 60 are brought into contact only in a contact region 50; this region is separated from the semiconductor substrate 10 in a peripheral part by using grooves 30 which are deeper than a p-n junction region 20. Since an element isolation region 90 is formed in the P-side ohmic electrode 60, light-emitting elements are separated electrically inside a wafer. Accordingly, when an N-side electrode is taken out from the whole surface of an N-side ohmic electrode 70 and an electric current flows to a gold-plated layer 80 on the P-side ohmic electrode 60 of the individual light-emitting elements, a beam is radiated through a silicon nitride film 40 from an optical output face 100; this beam is reflected by an optical reflection face 110 at an end part of an adjacent element facing the optical output face 100; the beam is taken out in a vertically upward direction; accordingly, a photodetector is arranged in parallel with a wafer face. Thereby, it is possible to accurately evaluate an optical output characteristic of the light-emitting elements on the wafer.

Abstract: PURPOSE:To supply fuel under stabilized control by a method wherein the title device is provided with a first pump, pumping the fuel up from a fuel tank, a vessel equipped with a leveler, and a second pump which is driven based on a control signal to supply the fuel in the vessel into a combustion device. CONSTITUTION:A first pump 14 is used only for pumping fuel up from a fuel tank 12 into a vessel 13 equipped with a leveler exclusively through continuous operation. A second pump 11 supplies the fuel from the vessel 13 to a burner 10 to burn it, heat dry air and increase drying capacity. The pump 11 changes the pumping amount of the fuel delicately by the control signal of a control unit 9. In this case, the control of the pump 11 is effected considering an atmospheric temperature,hot air temperature, atmospheric humidity and the temperature of grains. The pump 11 is operated with a pressure coping with a lift F2 and, therefore, the pump 11 reacts immediately even when the change of control amount DELTAF is applied. In this case, when the change of control amount DELTAF affects in the side of plus with respect to the lift F2, the number of driving pulse of the pump 11 is increased from (F2) to (F2+DELTAF) proportionally. On the other hand, when the change of control amount DELTAF affects in the side of minus with respect to the lift F2, the number of driving pulse of the pump is decreased to (F2-DELTAF) proportionally and the amount of control affects the driving of the pump 11 directly whereby the control of the supply of the fuel can be ensured.
