Title: Automatic white balance module
Inventor: FUKUDA HIROAKI
IPC: H04N5/378
Filed: 1989-02-03
Abstract: PURPOSE:To form an automatic white balance module with a few incident angle dependency of incident light by exercising a grain effect in order to increase a diffusing effect on a diffusion plate. CONSTITUTION:The automatic white balance module is provided with a light receiving device (automatic white balance sensor) 11, which has plural light receiving elements 10 at mutually different spectral sensitivity, an infrared ray cutting filter 14, which interrupts incident light 13 in an infrared ray area arranged on a light receiving surface 12 side of the light receiving device 11, and a diffusion plate 16, which is arranged on an incident plane 15 side of the infrared ray cutting filter 14 and diffuses the external incident light 13. Further grain processing is executed on the surface of the diffusion plate 16 in order to increase the diffusing effect. Thus since the grain effect is exercised in order to increase the diffusing effect on the surface of the diffusion plate 16, even when the incident light 13 is made incident on the diffusion plate 16 from the direction deviated from the vertical direction, the output characteristic of the light receiving device 11 is not changed, and the dependency of the incident light on the incident angle can be reduced.

Title: Sheet feeding device and image forming device
Inventor: TAKASHIMA KAZUNORI
IPC: B65H3/56
Filed: 1995-02-15
Abstract: PURPOSE: To reliably operate an overlap-feeding preventing member even if the moving amount of an intermediate plate is small. CONSTITUTION: An intermediate roller holder 13 is provided on an intermediate plate 12 so as to be oscillated, a cam for raising/lowering the intermediate plate is brought in contact with the upper surface of the intermediate plate roller holder 13, and a lever part 20-1 of an overlap-feeding preventing claw 20 is brought in contact with the lower surface. Since the moving amount of the intermediate roller holder 13 can be taken larger than the moving amount of the intermediate plate 12 even if the loading amount of sheets is large, the movement of the overlap-feeding preventing claw 20 is reliably performed.

Title: Setting processing system for interruption number
Inventor: KIKUCHI MITSURU
IPC: G06F9/46
Filed: 1995-02-15
Abstract: PURPOSE: To provide an interruption number approval processing system capable of easily managing an interruption number and avoiding the overlap of the interruption number by defining an interruption processing program and the interruption number in a definition registration part beforehand. CONSTITUTION: This system is provided with the definition registration part for registering the defined information of an interruption processing program identification code and the interruption number, a registration means for registering an interruption processing start address in an interruption table provided with the same interruption number as the defined interruption number and an interruption number setting means for detecting the interruption number from the definition registration part and storing it at the time of first internal interruption. Thus, the interruption number is changed by changing the interruption number to be defined and registered in the definition registration part. When the interruption number overlaps, the overlap is dissolved by changing the interruption number to be defined and registered in the definition registration part.  Since the interruption number is changed just by changing the defined contents of the definition registration part, the interruption number is easily changed.

Title: Tape guide device
Inventor: YOSHII TETSUJI
IPC: G11B15/60
Filed: 1988-02-08
Abstract: PURPOSE:To perform the temperature compensation of tape traveling characteristics by providing a rotatably supported tape guide roller and a thermosensitive deformable member provided in the vicinity of the tape guide roller. CONSTITUTION:The thermosensitive deformable member 8 is constituted in a bimetal type or formed out of a shape memory alloy, etc., in a bent washer shape and then fitted coaxially underneath the tape guide roller 1. The tape guide roller 1 is supported with a slight gap in the axial direction so as to be rotatable. Then, since the thermosensitive deformable member 8 is specifically deformed at more than a prescribed temperature or less than the prescribed temperature to stop the rotation of the tape guide roller 1, the tape tension can be prevented from lowering, etc. By this method, deterioration in tape traveling characteristics is compensated so as not to change too much the characteristics, thus extending the usable temperature range.

Title: Overcurrent preventing circuit
Inventor: TAKEDA TOSHIYUKI
IPC: H03H5/00
Filed: 1994-01-31
Abstract: PURPOSE:To protect circuit components while enhancing the stability in the operation of a current drive circuit and the accuracy of current value by comparing the voltage across a resistor connected in series with a load with a reference voltage and turning a FET OFF upon occurrence of an overcurrent thereby limiting or interrupting the load current. CONSTITUTION:A voltage comparing circuit 11 with hysteresis compares the voltage across a resistor 8 connected in series with a load 1 with a preset reference voltage +Vref. When an overcurrent flows through the resistor 8, a protective transistor 6 functions to equalize the source-drain voltage of a FET 5 and the collector-emitter voltage of a transistor 6 thus turning the FET 5 OFF and limiting or interrupting the load current. This circuitry protects the circuit components and enhances the stability in the operation of a power supply drive circuit and the accuracy of current value.

Title: Image processor
Inventor: FURUYA YOJI
IPC: G06F3/038
Filed: 1991-02-21
Abstract: PURPOSE:To reduce non-creative work such as a frequent cursor movement even when the operation is performed between positions located far from each other on a display screen by restricting several coordinate input means which can specify and input a coordinate position to one means at a time. CONSTITUTION:With the advance of one frame of the image of 'walking action of a human' by setting a mouse cursor A33 to the frame feed menu of a drawing window 31 and clicking a mouse A button, the image is recorded for each frame to a VTR12 by setting a mouse cursor B34 to the frame recording menu of a VTR control window. During the work, each time the button of mice A and B are alternatively pressed by a user, a drawing window 31 and a VTR control window 32 are alternatively changed over between an active state and an inactive state. Thus, by connecting two mice to one PC system, two positions are simultaneously indicated and operated on the screen.

Title: Manufacture of semiconductor device
Inventor: ORIHARA KOZO
IPC: H01L21/768
Filed: 1988-02-10
Abstract: PURPOSE:To prevent short-circuit defects between electrodes, by forming an oxide film and first electrodes comprising first polycrystalline semiconductor 5 on a substrate, thereafter selectively removing a side wall layer, oxidizing the substrate and the first polycrystalline semiconductor 5, and forming second electrodes comprising second polycrystalline semiconductors on the obtained oxide film. CONSTITUTION:A field oxide film 202 and first electrode layers 203 and 204 comprising polycrystalline silicon are formed on a silicon substrate 201. Thereafter, a silicon nitride film 205 is formed. The silicon nitride film 205 is removed by anisotropic dry etching so that only a side wall layer 205a is made to remain. Then, a part of the field oxide film 202 on the silicon substrate 201 is removed. The oxide film 202 is made thin. Thereafter, the side wall layer 205a is removed. Then, after an oxide film 210 is newly formed, a polycrystalline silicon film 211 is deposited, and second electrode layers 212 and 213 are formed. Since the polycrystalline semiconductor does not remain at an undercut part in this way, short-circuit defects between the electrodes are prevented.

Title: Light pen device
Inventor: TOTSUGI SEIJI
IPC: G06F3/037
Filed: 1981-02-27
Abstract: PURPOSE:To draw a straight line toward a direction not fixed on a screen without tremulous handwriting, by fixing either one of X and Y coordinates. CONSTITUTION:When a switch SW2 is at off-mode, and when a pen switch pulse is inputted to a terminal 55 of a gate circuit 5, the output of the circuit 5 goes to high level. Thus, since a light pen pulse outputted at each field from a light pen 1 is given to a latch circuit 3 via an AND gate 4, the similar operation can be obtained as a conventional light pen device. When the switch SW2 is at on- mode, the output of the circuit 5 keeps high level only during one field. As a result, only one of light pen pulses outputted from the light pen 1 is given to the circuit 3. Thus, the count value outputted from an X address counter 2 is renewed by once and the content is kept afterward, allowing to renew only the Y coordinate, when the pen 1 is shifted toward the Y.

Title: Feed screw
Inventor: SHINOHARA TANEHIRO
IPC: F16H25/12
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a feed screw that reduces its coefficient of friction even under a high load. SOLUTION: This feed screw comprises a screw shaft 1, a nut 2 and a linear guide surface 13, to the space between which screw shaft and nut is supplied lubricating oil. The screw shaft 1 is formed in its thread ridge top 4 with holes 3 spaced out evenly at a preset pitch along the thread ridge. Since the areas around the holes 3 have lowered rigidity and thus larger flexure, on receiving a load the tooth flanks experience circumferential, concave deformation periodically to thereby form circumferential waviness. While the screw shaft 1 and nut 2 undergo a relative movement between their faces opposed to each other, the waviness causes an oil film pressure F and thus a load capacity W' in the region in which a wedge oil film 6 is formed in the direction of sliding movement. This load capacity W' serves to support these two faces through the oil film 6.
