Title: Modulation-doped photo detector
Inventor: NIWA MASARU
IPC: H01L21/338
Filed: 1985-05-24
Abstract: PURPOSE:To make high speed response possible in the leading edge and the trailing edge of a signal current, by providing the positive hole current which is contained in the electron-positive hole pair generated in the photo absorbing layer to the external circuit through this electrode. CONSTITUTION:The P-type positive hole current drawing up layer 22, the N-type photo absorbing layer 23, the spacer layer 24 to produce the undoped two-dimensional electron gas and the N-type electric charge supplying layer 25 are formed on the semi-insulating semiconductor substrate 21. With respect to electrode, the source electrode 28, the drain electrode 27, the gate electrode 28 and the positive hole current drawing up electrode 29 are formed. The electron-positive hole pair is generated in the layer 23 by the incidence of light into this device. In a very short period of time, the electron of the pair reaches the two-dimensional electron gas region, and can be taken out as a signal current between the electrodes 28 and 27. In case the layer 22 is provided, the positive hole can be drawn bias through the electrodes 26 and 29. Thus, the slow component coursed by the diffusion of positive hole can be eliminated and the high speed response can be obtained.

Abstract: PURPOSE: To make it possible to prevent the generation of semi-molten substances in a furnace and inhibit the growth of deposited substances on the surface of the furnace by mixing a gas whose oxygen concentration is lower than that of air with normal temperature air from an upper stage tuyere and blowing the mixed gas into a melting furnace and lowering the combustion temperature in the upper stage tuyere area than the melting temperature of ash contents. CONSTITUTION: On the downstream of a melting furnace 1 there are laid out a secondary combustion chamber 2, a waste heat boiler 3 and a dust collector 4 one by another where a stack 5 is laid out on the final stage. The melting furnace 1 is provided with a shaft 1a and a bosh 1b. What is more, the bosh 1b is provided with a lower stage tuyere 1c as well as second stage tuyeres 1d and 1e. A mixture of air and oxygen is supplied from the lower stage tuyere 1c while normal temperature air is supplied to the upper stage tuyeres 1d and 1e. In this case, a gas which is proper at a temperature and low in the concentration of oxygen, is supplied from the upper stage tuyere 1d, thereby inhibiting the generation of semi-molten substances.  More specifically, low temperature exhaust gas including residual oxygen which is purified with the dust collector 4 and heat-exchanged by way of a waste heat boiler 3 is supplied into the furnace from the upper stage tuyeres 1d and 1e together with the normal temperature air.
