Title: Video projector
Inventor: ICHII YUTAKA
IPC: G02F1/13
Filed: 1995-05-26
Abstract: PURPOSE: To provide a video projector which can improve its productivity and also can improve the image quality by emitting the green image beam from a 1st optical modulation type display and then emitting the blue and red image beams in two divided areas from a 2nd optical modulation type display. CONSTITUTION: The green image beam is emitted from a picture frame 6a of a 1st optical modulation type display 6 in an ordinary image size. At the same time, the blue and red image beams are emitted independently of each other from the image areas 9a1 and 9a2 which are vertically divided out of a picture frame 9a of a 2nd modulation type display 9 in a compressed state against the ordinary size only in the horizontal or vertical direction. Then the red and blue image beams emitted in a state where the ordinary size is compressed are turned into the original image size by the optical expansion means 17 and 18. Furthermore, the green image beam and the red/blue composite image beam are magnified and projected in a single red/green/blue composite image beam by the optical image composition/emission means 20 and 21.

Title: Stencil printing device
Inventor: HASEGAWA TAKAKUNI
IPC: B41L13/14
Filed: 1988-06-22
Abstract: PURPOSE:To ensure the engagement of base paper with a clamp piece on a plate cylinder at the time of a plate loading and the discharge of the base paper after the release of clamping at the time of a plate unloading by providing a base paper guide member displacing with the rotation of the clamp piece upwards of the plate cylinder coming into contact with the rotating clamp piece. CONSTITUTION:A leading end of stencil base paper S is fed to a plate cylinder 3 and fastened. At this time, a clamp piece 9 separates from a magnet board 6 to rotate toward a magnet board 7. Then, at the time of this action, the top end of the clamp piece 9 comes into contact with the lower surface of a flexible guide member 40 to bend the guide member 40 upwards. After the completion of printing, the clamp piece 9 of a base paper fastening device 4 rotates while bending the guide member 40 to be attracted by the magnet board 6 on the other side, thus releasing one end of the stencil base paper S. In the loading/unloading of the plate, sometimes the fastened end thereof may be warped and curled in the direction of separating from the peripheral surface of the plate cylinder 3. However, since the guide member 40 is disposed upwards of the clamp piece 9, the top end of the stencil base paper S is surely guided over the full width thereof.

Title: Data point storing and accessing method
Inventor: STEVEN J HARLINETON
IPC: G03F3/08
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To simultaneously output four values while using a memory of the same capacity by lOading four data points in four memories, receiving a color value for translation to an address, using the integer part of the address for positioning, while using the decimal part for determining a tetrahedron, and accessing values to be stored at four corners of the tetrahedron to be used for interpolation. SOLUTION: First of all, 64 data points are loaded from a memory A22 to a memory D25. In order to access data, the RGB output of a scanner 28 is translated into an memory address by an address generator 29 having an integer part (int) and a decimal part (f). Three integer parts and their increment values are inputted to a logic 21. The first job of the logic is easily performed by addressing a start point P000 of a selected solid body and addressing the P1000 while connecting the integer parts of (x), (y) and (z). Three integer Parts generate the address of a memory B at the start point of a current solid body.

Title: Character and pattern reader
Inventor: ISHIKAWA HIDEHO
IPC: G02B26/12
Filed: 1977-12-19
Abstract: PURPOSE:To make high speed reading and mechanism simple by a linear image sensor of a multiplicity of elements simultaneously scanning for one line and a rotary mirror for longitudinal scanning. CONSTITUTION:Paper 1 having been delivered from a hopper is sucked to the inside surface of a drum and stops. A line sensor 3 which has the number of elements enough to cover the width of the paper with a multiplicity of elements permits scanning in the transverse direction through electrical scanning. While 1 line is being scanned by the sensor 3, a rotary mirror 5 is rotated in a fixed direction, by which longitudinal scanning is performed and the image plane is subsequently scanned and read. The rotating speed for reading of the mirror 5 can be lower than that in ordinary systems, thus reading accuracy is improved. If the speed is increased, high speed reading is feasible. In the case of making rereading owing to illegible characters or reading failure, returning the rotary mirror makes rereading readily possible. 6 denotes an imaging lens, 7 a light source and 8 a condensing lens.

Title: Control of line-feeding pulse motor in printer
Inventor: TANUMA JIRO
IPC: B41J11/38
Filed: 1986-07-01
Abstract: PURPOSE:To prevent step-out of a motor from occurring even upon a large change in load, by causing an LF motor to generate a holding torque of such a magnitude that a printing medium can not be manually fed, during spacing and printing operations. CONSTITUTION:A printer remains in a ready state until data are supplied from the host side, and in view of the manual feeding performed by the operator for setting a printing medium, a HOLD signal is set to a 'high' level, so that a holding torque of an LF motor 6 is as low as that in a conventional system. When data are supplied from the host side to the printer and printing and line-feeding operation are started, printing is started, and the HOLD signal is switched to a 'low' level. The HOLD signal is maintained at the 'low' level until it can be confirmed that the last printing or line-feeding operation is completed and the ready state is obtained due to the absense of data, and after such a condition is confirmed, the HOLD signal is again switched to the 'high' level. By this, the holding torque of the LF motor 6 during a printing operation is increased to a level of HOLD. In the case of a line-feeding (LF) operation, the printing medium if fed by utilizing the highest rotating torque, as in the conventional system.

Abstract: PURPOSE:To prevent the generation of bubbles in the molding section of a molded product, to which extremely thin molding is executed, by thinning the thickness of a section corresponding to the peripheral section of the principal section of a material to be molded. CONSTITUTION:The section corresponding to the peripheral section of the principal section of the material to be molded such as the molding section 16 of the upper surface of leads 18 corresponding to a pellet 17 is formed thinly. That is, the section corresponding to the peripheral section of the pellet 17 of the cavity of a molding top force is thinned, the inner surface of the upper side of a corresponding molding die is projected, a flow path for a resin is narrowed, and the pipe resistance of the flow path is increased, thus reducing the velocity ratio of the flow of the resin flowing on the pellet 17 to the flow of the resin flowing on the circumferential fringe of the pellet 17. Accordingly, the flow on the pellet of the resin is slower than the flow of the resin around the pellet, but a closed space to be generated as the result of the resin going around onto the pellet from both sides is prevented from occurring.
