Title: Scanning converter
Inventor: SHIYOUNAKA ATSUSHI
IPC: H04N7/01
Filed: 1988-01-20
Abstract: PURPOSE:To suppress picture fog of a moving part and to improve the picture quality remarkably by providing a brightness control means and applying reduction control to the brightness level of an interpolation data as movement is larger. CONSTITUTION:A brightness of a data Db from an interpolation data generating section 10 and that of a data Da from a field memory section 8 are given respectively to one and other of two multipliers of a brightness adjustment section 14, the brightness level of the data Db is subjected to reduction control by reduction correction characteristic of one multiplier to form a data Db' and the brightness level of the data Da is subjected to emphasis control by other multiplier to form a data Da'. In most cases, since the brightness level of the moving part is an average level or over, the video signal formed by the scanning conversion to a time base conversion section 9, in its contour of the moving part, depends only on the brightness level of the data Da as the movement is larger and sharpened more and the picture fog of the moving part of the reproduced part is suppressed and the picture quality is improved.

Abstract: PURPOSE:To diminish an eccentric amt. and an inclination of an optical disk due to its mounting to a spindle and to improve the reliability by applying a coating film to the outer peripheral part of the spindle shaft of a spindle rotating mechanism to be fitted into a centering part for positioning the optical disk. CONSTITUTION:When the optical disk 6 is rotated with the spindle 2 by a motor 15 in its drive, a carriage 11 is instructed by a positioning control circuit to perform a seek operation upon receipt of a positioning command from a host device, and an information recording or reproducing is carried out with an optical head 12 in the commanded specific position. In this case, since the coating film 9 is applied on the outer peripheral surface of the spindle shaft 8 to be fitted into a hub 7 of the centering part for positioning the optical disk 6, when the optical disk 6 is mounted to the spindle 2, the mounting can be carried out smoothly and perfectly without generating a scuffing phenomenon between the fitting parts, thus diminishing the eccentric amt. and inclination of the optical disk 6 when mounted on the spindle 2.

Filed: 1993-01-27
Abstract: PURPOSE:To shorten communication time and reduce communication cost by sending data in a format which is as small in communication amount as possible according to equipment at a transmission destination. CONSTITUTION:A connection with an external line 3 is made to call the transmission destination 4 and once the transmission destination is connected, sent data on the kind and performance of the equipment at the transmission destination are checked. Then, a CPU 5 as a selective transmitting means decides whether or not code data transmission is possible from the received data. When not, namely, when the equipment at the transmission destination is facsimile equipment, the equipment can receive only image data, so the code data are converted into image data as usual and the image data are sent. When the equipment at the transmission destination has a function for converting the code data into the image data, the code data are receivable, so the code data need not be converted and sent as they are; and the external line 3 is disconnected and the transmission is ended.

Title: Method and device for developing
Inventor: TOYONO TSUTOMU
IPC: G03G15/06
Filed: 1979-02-06
Abstract: PURPOSE: To achieve the improvement in the reproducibility of image end part and the gradation characteristic of visible images by accelerating the transfer of the developer from a developing material substrate to a latent image holder thence reverse-transferring the developer having transferred to non-image part.  
     CONSTITUTION: DC voltage is applied to a sleeve 12 by a power source 16 and a development accelerating part A is formed near the minimum spacing. Hence, in the image part, a large amount of developer surely deposits even to the end part. Since relatively weak electric fields act in the non-image part, a slight amount of the developer deposits, creating a some ground fog state. Thence, DC voltage is applied to a reverse transfer electrode 18 by a power source 21, whereby the reverse transfer part B is formed. Because of this, a slight amount of toner is stripped off from the image part and the toner having deposited on the non-image part completely reverse-transfers on the reverse transfer electrode 18. In a medium contrast region, the toner pickup is determined by the magnitude of the transfer amount of the developer according to holding potentials, hence the good quality images of high gradation characteristic and superior reproducibility of line images are obtained.

Abstract: PURPOSE: To prevent errouneous operation by providing, for example, a high- purity-alumina α-ray-screening plate having excellent heat resistance around a semiconductor element.  
     CONSTITUTION: A step 10 is provided on a ceramic base plate 3 wherein inner laeds 6 and a cavity 8 are provided. An element 5 is placed and Au wires 7 are connected to the leads 6.

Abstract: PURPOSE: To secure the accurate reading of the picture infomation on the two- dimensional original by installing the detector to the mirror near the original and then setting the shift velocity of this mirror to the double velocity of the other mirror.  
     CONSTITUTION: Mirrors 8 and 9 are distributed under the face of original 4 with their reflective faces opposed to each other. Thus beam 2 sent from laser 1 is irradiated on face 4 of the original through condenser lens 3 and via mirrors 8 and 9, and the reflected light of beam 2 from face 4 is detected by detector 7. At the same time, light deflector 5 is provided to the irradiation optical system in order to carry out the scanning of the main scanning direction. Also mirrors 8 and 9 can move in the secondary scanning direction, and photo detector 7 is installed to mirror 8 which is closer to original 4. In this case the shift velocity of mirror 8 is set double the velocity of mirror 9. As a result, the picture information on two-dimensional original 4 can be read accurately.

Filed: 1989-01-23
Abstract: PURPOSE:To realize a low-cost and compact light source with a stable output in a simple structure by guiding irradiated light from a light-emitting element on a substrate to the other edge surface of the substrate and providing a waveguide path of light irradiated as a parallel light flux or focusing light flux. CONSTITUTION:Irradiated light from a light-emitting element 11 is enclosed into a light waveguide path 12 and one part of it is branched into a light Waveguide path is and is allowed to inside a light-receiving element 14. The remaining large part of light passes through a light waveguide path IG and is irradiated from the edge surface of the substrate. At this time, the light waveguide path itself acts as a lens and thus selecting a diffraction factor distribution and the length of light waveguide path 12 properly enables the irradiated light from the edge surface to be a parallel light flux. Branching of light and conversion (lens operation) into parallel light flux are performed within one substrate by light source configured this way.
