Title: Method of controlling and preventing malfunction by noise in ice making device
Inventor: KATAYANAGI HIDEYUKI
IPC: F25C1/00
Filed: 1992-03-09
Abstract: PURPOSE:To prevent runaway of the above device due to the occurrence of a loud noise that may cause adverse effect on a microcomputer and the like by a method wherein a plurality of loads are turned ON or OFF while lagging a very short period of time among them when steps of an ice making cycle are changed over. CONSTITUTION:In the case where a plurality of loads, for example, a compressor 1, a hot gas valve 6 and a water feed valve 8, are turned OFF when steps of an ice making cycle are changed over, determination is made repeatedly as to whether a specified very short period of time, for example, several tens to several hundreds of milliseconds have elapsed after the compressor 1 is turned OFF. After ascertaining the lapse of a specified very short period of time, the hot gas valve 6 is turned OFF and, in a similar way, the water feed valve 8 is then turned OFF after the lapse of a specified very short period of time. Accordingly, noises occur separately without causing adverse effect on a microcomputer and the like in a controlling means. Although a very low noise occurs intermittently, there is no possibility of the occurrence of a loud noise that may cause adverse effect on the microcomputer and the like.

Title: Wire electric discharge machining device
Inventor: TANAKA MAKOTO
IPC: B23H7/02
Filed: 1988-04-07
Abstract: PURPOSE:To prevent the occurrence of poor machining precision of a workpiece due to deformation of a lower arm occasioned by an external force by a method wherein a machining liquid injection means is situated to a slide part between a bellows and a guide. CONSTITUTION:During execution of machining, machining sludge is mixed in machining liquid injected through upper and lower wire guide means for splash. Machining sludge splashed in a manner described above is about to be deposited between a bellows 34 and a guide 34a of a splash preventing means 28. However, through injection of clean machining liquid through a filter 74 by means of a machining liquid injection means 50, the machining sludge is discharged through a gap between the bellows 34 and the guide 34a. Thereby, bellows slide resistance is not generated, a lower arm 26 is prevented from bending, and relative displacement in a position in a vertical direction between the upper and lower guide means is not generated, resulting in the possibility to perform machining with high machining precision.

Title: Data surface servo system
Inventor: UNO KOUJI
IPC: G11B5/58
Filed: 1982-05-21
Abstract: PURPOSE:To facilitate the readout of tracking information, by recording both the data information and the tracking information in the same recording picture and then varying the azimuth angle in order to reduce the mutual interference. CONSTITUTION:In a diagram showing that a part of a track of a magnetic recording medium, the layer having a sharrow recording surface consists of a magnetic substance 5 of small coercive force. While the layer having a deep recording surface consists of a magnetic substance 6 of large coercive force. The data information is recorded in a state 7; while the tracking information is recorded in a state 8, respectively. The azimuth angles of the states 7 and 8 are plus and minus, respectively. This system reduces the mutual interference in a reading mode. The tracking information of a deep layer has large coercive force and therefore receives a reduced effect when the data information is recorded.

Title: Manufacture for structure of semiconductor device
Inventor: GEIRII ANSONII DAPINTO
IPC: H01L21/205
Filed: 1991-01-28
Abstract: PURPOSE: To improve the adhesion method of polycrystalline silicon when forming a contact when manufacturing a semiconductor device. CONSTITUTION: In polycrystalline silicon films 22 and 23, electrical characteristics in wafer units need to be relatively uniform when being used, for example, as resistance. For achieving uniformity, a wafer temperature for providing the polycrystalline silicon must be identical within a narrow tolerance. A reaction occurs in an oven and it takes much time until a required temperature tolerance is reached. The oven stabilizes temperature but an oxide that is an insulator begins to grow at the contact position of each substrate 11. For minimizing the formation of a harmful oxide, the polycrystalline thin film 22 is adhered long time before the oven becomes stable, thus securing an improved low-resistance contact.  The remaining part 23 of the polycrystalline silicon is adhered on the polycrystalline silicon thin film 22 after temperature becomes stable, thus obtaining a uniform resistance in required wafer units.

Title: 1/n operation check system
Inventor: ITOU YUKIO
IPC: H04Q1/20
Filed: 1979-07-10
Abstract: PURPOSE:To enable the same checking circuit to make a 1/n operation check on row and column selecting drivers by putting a switch, provided between the row or column selecting driver and an electric power source in a switchboard, into operation in load drive. CONSTITUTION:Between a Y-side driver and electric power source E2, switch Z is interposed and switch Z cuts off electric power source E2 temporarily to develop the potential of electric power source E1 at the driver. For example, when switch Z is not in operation and only X0 and Y0 drivers are put into operation, electric power source E2 is isolated from the driver via switch Z and the potential across X0, point a0, load L00, Y0 and point b0 is held at E1. As voltage-detecting type 1/n operation checking circuits 2, 2, the same checking circuit can be used if points (a) and (b)  are equal in potential. Then, circuit 2 has input impedance set much greater than that of the load and driver, and when only X0 and Y0 drivers are in operation, a  fine current flows, thereby drivers are checked without exerting an influence on the  operation of the load.

Abstract: PURPOSE:To improve the operability, and to shorten the operation time by constituting the titled reader so that the first and the second mirrors which have been provided in an optical system move by interlocking with a movement of a head, and a light beam always scans a bar-code on the surface to be scanned in the vertical direction. CONSTITUTION:A light beam of a light source 7 passes through a fixed mirror 11, a perforated mirror 12, and a hologram plate 9, and also, passes through the first mirror 14 and the second mirror 15 which move by interlocking with a movement of a head, and scans on a bar-code 16 of a commodity. A reflected light from the code 16 is condensed to a photodetecting part 10 by the plate 9 as shown by a dotted line, converted to an electric signal, and the code 16 is decoded. At the time of irradiating the code 16, when the head is moved in accordance with a size of the commodity, the mirrors 14, 15 rotate around points B, D, and the light beam changes its direction, and always irradiates the code 16 in the vertical direction. In this way, the operability against a size and a shape of the commodity is improved, and the operation time can be shortened.

Abstract: PURPOSE:To improve an S/N near a black level and to make noise inconspicuous in the black area of an image even when gamma correction having a high amplification factor near the black level of a video signal is executed by a digital signal processing. CONSTITUTION:An HPF 11 extracts the high frequency component of an input video signal from an A/D converter 4. A level detector 12 detects the level of the input video signal. A multiplier 13 amplifies the output of the HPF 11 while being controlled so as to enlarge the amplification factor near the black level corresponding to the level of the input video signal from the level detector 12. An adder 14 subtracts the output of the multiplier 13 from the input video signal and outputs the added result to a camera process circuit 5 composed of a gamma correction circuit or the like.
