Title: Manufacture of semiconductor device
Inventor: NOGUCHI KOU
IPC: H01L29/78
Filed: 1989-03-03
Abstract: PURPOSE:To form a gate electrode in a minute shape by forming a spacer on the side wall of a hole part in a gate-electrode forming region on a semiconductor substrate, thereafter forming a low-concentration diffused layer in the semiconductor substrate, then removing the spacer, and thereafter forming a gate insulating film and the gate electrode in the hole part in a self-aligning mode. CONSTITUTION:An element isolating silicon oxide film 2 is formed on a semiconductor substrate 1. An oxide film 3 is deposited on the substrate 1. Thereafter, a hole part is formed in a gate-electrode forming region. Then a PSG film is formed. When the PSG film undergoes anisotropic etching, a PSG film 4 is formed only on the side wall part of the oxide film 3. Heat treatment is performed in nitrogen atmosphere, and the phosphorus is diffused into the semiconductor substrate 1 from the PSG film. Thus, an N-type low-concentration diffused layer 5 is formed. Then, the PSG film 4 is removed. After that, a gate oxide film 6 is formed on the semiconductor substrate at the hole part. Polycrystalline silicon 7 which is a gate electrode material is deposited. Thereafter, an N-type high-concentration diffused layer 8 and an aluminum electrode 10 are formed. Thus, the gate electrode can be formed with good controllability.

Abstract: PURPOSE:To easily perform a unitary management for a system, by providing an information collecting station in a loop network system. CONSTITUTION:The titled system is formed so that stations (ST) are connected to a loop-shaped transmission path 1, and data sent out from a station is returned to a transmission original ST passing through respective station in arrow head direction. When a transmission frame is sent out from a transmission station (S-ST), and it is received by a reception station R-ST, the transmission station S-ST checks whether a reception is received correctly or not by the reception station R-ST, and when is not received correctly, a field F(80)16 in the transmission frame is sent again. And all of the transmission frames of the fields F(80)16 are collected by an information collecting station (M-ST) as defective telegrams. In this way, even when some fault is generated on the transmission path, and the transmission frame is designated as the defective telegram, a centralized collection for bits of information can be performed automatically.

Title: Production of silicon wafer and the resultant silicon wafer
Inventor: NAKAMURA KOZO
IPC: H01L21/324
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To obtain a silicon wafer by heat treatment of a green silicon wafer in an atmosphere of a dew point-controlled mixed gas of hydrogen gas and an inert gas so as to eliminate defects developed during single crystal growth process using the silicon wafer. SOLUTION: This silicon wafer is obtained by CZ method by heat treatment of a green silicon wafer in an atmosphere of a mixed gas comprising hydrogen gas and an inert gas and controlled in dew point according to a specified formula. By controlling the dew point of the mixed gas to a specified level or lower, the dryness degree of the mixed gas is kept at a specified level, resulting in suppressing the water vapor content of the mixed gas to a specified level or lower. Therefore, in such a mixed gas atmosphere, oxidation reaction is hard to proceed, and furthermore, because the hydrogen gas has been diluted with the inert gas, the wafer is prevented from contamination due to the gasification of heavy metal impurities by the hydrogen gas, thus affording the objective high-quality silicon wafer.

Title: Digital picture producer
Inventor: TAKAGI YOUICHI
IPC: G06K15/12
Filed: 1980-04-23
Abstract: PURPOSE:To prevent the deterioration of quality for a picture recorded on a film, by using the two picture buffer memories in switch and providing a rotary disk to cut off the afterglow for a device that records a digital picture on a film. CONSTITUTION:The luminous flux 391 sent from the light source 301 is modulated by a modulator 303, and the picture signals sent from the CPU200 are stored alternately into the two buffer memories in the interface 370 to be delivered alternately to the modulator 303 in the form of modulated signals. As a result, the nonmodulation period during which the modulator 303 gives no modulation to the flux 391. The modulated luminous flux 392 passes through the rotary disk 306 having an unevenness on its circumference. Thus the disk 306 cuts off the nonmodulated luminous flux at its convex part. Thus flux 392 scans a line of film via the rotary mirror 312. Thus the afterglow (nonmodulated light) can be reduced by switching the two buffer memories alternately, and the afterglow is cut off by the rotary disk. As a result, no afterglow is recorded on the film.

Abstract: PURPOSE:To provide a power supply in which surge current is eliminated and distortion of input current is suppressed while enhancing input power factor and conversion efficiency. CONSTITUTION:A chopper circuit can set a booster chopper operation or a step-up/step-down chopper operation by means of a switch element SW1.

Title: Bent injection molding machine
Inventor: KASAI MASAYOSHI
IPC: B29C45/00
Filed: 1981-04-09
Abstract: PURPOSE:To promote the gelling of a vinyl chloride resin powder for raising the plasticizing capability of a bent injection molding machine by providing a mixing portion having a polygonal cross section before the ring valve of the molding machine in such a way as to form circle-deficient portions between the polygonal side and the inner wall of the cylinder. CONSTITUTION:A mixing portion M having a polygonal, axially right-agled cross section is provided before the first stage ring valve 3, and circle-deficient spaces h of the same number as polygonal bodies g are formed between the notched slopes 10 of the polygonal bodies g and the inner wall 11 of the cylinder 11. The mixing portion M can provide a slight distorsion to a screw 1. Since the ring valve 3 can stop the flow of resin, semi-molten resin j flows in the direction of arrow in the mixing portion M as the screw 1 turns, and since the circle- deficient space h has a tapered wedge-shaped structure in the flow direction of the resin, vinyl chloride resin powder, etc., to be hardly gelled can advance along the arrow direction. As the screw 1 turns, the resin is strongly pressed on the inner wall 11 of the cylinder by the wedging action of the notched slope 10, whereby the gelling of the resin can be quickly accelerated by the action of a shearing energy to form a resin free of dispersion in kneading degree.
