Patent JP-S61188364-A (JP)
Title: Recording device
Inventor: SETO KAORU
IPC: G03G15/00
Filed: 1985-02-15
Abstract: PURPOSE:To make it possible to confirm the transferring position and condition of a sheet directly by a visual checking, by indicating the detection of a sheet with the use of a plurality of sheet detecting means arranged along a sheet transfer path. CONSTITUTION:When a sheet 1 on transfer passes a position in opposite to any one of photosensors 17-23 which are arranged at suitable positions along a sheet transfer path, the light reflected from the sheet 1 is received by the corresponding photosensor which therefore delivers a sheet detection signal to indicate the detection of the sheet on an indicator panel 25 on which a silk printing is made to exhibit a schematic pattern of the sheet transfer path, having photodiode indicators arranged at positions corresponding to the positions of the photosensors on the transfer path. Thus, it is possible to directly trace the transfer passage of the sheet 1 by visual checking of the turn-on and -off of the photodiode indicators.

Title: Method for etching sic pattern
Inventor: KOEDA MASARU
IPC: H01S5/00
Filed: 1993-02-16
Abstract: PURPOSE:To etch an SiC substrate to a desired shape at a high speed through a simple process and, at the same time, to obtain a smooth finished surface. CONSTITUTION:After forming a pattern mask of a resist material on an SiC substrate, reactive ion beam etching is performed by using a mixed gas prepared by mixing CBrF3 and Ar so as to satisfy the relation expressed by Ar/(CBrF3+ Ar)=50 to 95%. Therefore, a pattern can be directly etched from the surface of the resist without performing any lifting-off process, since the etching speed of the SiC substrate becomes almost equal to that of the resist.

IPC: H03K17/08
Filed: 1979-03-09
Abstract: PURPOSE:To improve antinoise performance by automatically closing a breaker again constant time after the breaker is tripped and then by carrying operation on as it is if a re-trip would not be done within a constant time. CONSTITUTION:Analog comparator 9 is given hysteresis characteristics and when the output of comparator 9 changes from a high level to a low level (down edge), one-shot circuit 10 is operated to output from the Q output of circuit 10 one-shot signal (e), which is passed through OR circuit 11 to reset FF2, thereby decreasing the Q output of FF2 down to the low level. Therefore when control circuit 14 is ON at this time, breaker 15 is closed again. Simultaneously, the output of NOT circuit 3 is held at the low level and the discharge of the voltage across capacitor 5 starts by way of GND, capacitor 5, resistance 4, and circuit 3 in the order. Further, if no abnormality of a main circuit current would not be detected 1, the operation is carried out (a) as it is and after period T2, output (d) of comparator 9 is inverted to set an initial state.

Abstract: PURPOSE:To decrease the contact of a molten metal with air and to avoid intrusion of air therein by inserting a ladle which can open or close the molten metal port in the bottom end part down into the lower part of an injection sleeve and rising the same under the specific condition while discharging the molten metal. CONSTITUTION:A molten metal port 4 of a ladle 1 is put under the oxide film on the surface of the molten metal in a furnace and a valve stem 5 is moved upward by a cylinder 6 to put the molten metal through the port 4 into the ladle.

Abstract: PURPOSE:To improve the sheet thickness control accuracy for a rolled stock by calculating a deformation amount and dividing the amount into a roll base and a housing base deformation amounts. CONSTITUTION:A deformation amount of a rolling mill for calculation of a gage sheet thickness is calculated and divided into a roll base and a housing base deformation amounts. That is, actually measured values such as a roll dia. and a sheet width are inputted to a data input part 31 and a roll base deformation amount is obtained by a roll base deformation amount calculation device 33 from a prescribed equation. A housing base deformation amount is obtained by a housing base deformation calculation device 32 by subtracting the roll base deformation amount at roll screwing time from a rolling mill deformation amount obtained from the elastic characteristic curve at roll screwing time. The control accuracy is improved because a roll opening controller 34 adds both the deformation amounts, calculates a roll opening, and controls the opening.
