Title: Darlington photo-transistor
Inventor: NAGASHIMA TOSHIYUKI
IPC: H01L31/10
Filed: 1982-03-17
Abstract: PURPOSE:To reduce a dark current to cause a noise current, and to obtain a highly reliable Darlington photo-transistor enabled to stabilize action of a circuit in the succeeding stage by a method wherein a resistor for by-pass is provided between the base and the emitter of a transistor for amplification of a photocurrent. CONSTITUTION:When light is irradiated to the base region of the photo-transistor Tr1, the photocurrent is generated in P-N junction forming the base and a collector, and the photocurrent thereof flows to the emitter side. The emitter current IE is distributed to the base and the by-pass resistor RBE of the transistor Tr2, and the dark current is reduced. When the voltage between the base and the emitter of the transistor Tr2 is designated as VBE, and the resistance value of the by-pass resistor RBE as (r), the maximum value IRMAX of a current to flow in the by-pass resistor RBE becomes as IRMAX=VBE/r. When the transistor Tr2 is formed of silicon, the voltage VBE between the base and the emitter is about 0.6V, and as the resistance value (r), 25-35OMEGA is the most suitable.

Abstract: PURPOSE:To display a picture by means of a buffer memory having small window display in a double buffer system by utilizing the display area of a frame buffer memory and the excessive part of the frame buffer memory. CONSTITUTION:For the window displayed by the double buffer, a window display processor 10 designates a window A on a display area 3A of a frame buffer memory 3 and a window B on an area 3B other than the display area 3A.

Title: Heat treatment unit
Inventor: AKASE KIYOSHI
IPC: C30B25/10
Filed: 1978-04-11
Abstract: PURPOSE:To obtain a heat treatment unit which can prevent wafer defects by fitting a heat reflection material near a coil. CONSTITUTION:First, wafer 11 is put on susceptor 12 so that one main face of wafer 11 may be  brought into contact with susceptor 12 and is put into quartz tube 13. Next, a voltage is applied  to coil 14 to subject susceptor 12 to induction heating. Consequently, the temperature of wafer  11 on susceptor 12 rises due to the heat conduction from susceptor 12 and the reflection heat  dependent upon reflection plate 21. Thought the radiated heat from susceptor 12 is reflected by  reflection plate 21, the needless heated radiated heat is emitted from exhaustion exit 16 which  epitaxial furnace main body 15 has. Continuously, H2 is flowed into quartz tube 13 as carrier gas,  and reactive gas such as silicon tetrachloride is injected to grow a single crystal Si layer on wafer  11. As a result, the temperature rise of wafer 11 is caused by the temperature rise from the lower  face of wafer 11 dependent upon the heat conduction from sucseptor 12 and the temperature rise  from the upper face of wafer 11 dependent upon the reflection heat from reflection plate 21 which reflects the radiated heat from susceptor 12, and wafer 11 is heated from the upper face and the  lower face, and the temperature difference in the wafer face is eliminated.
