Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To provide a data updating system capable of fairly and surely updating information stored in respective terminals to the information of a newest version by simple constitution without imposing burdens to users. SOLUTION: Software for a mobile object communication terminal 10 capable of updating position registration any time by known position registration processing is managed by a version number and an HLR 11 for registering the position registration information of the terminal 10 stores the version number of software of the newest version as newest version number information. When software of a new version number is registered in a server 12, a registration report is sent to the HLR 11 and the newest version number information is updated. The software version number of the terminal 10 is added to a position registration request outputted from the terminal 10 when required, and at the time of receiving the position registration request, the newest version number information stored in the HLR 11 is compared with the version number.  At the time of detecting non-coincidence, a push request is outputted to the server 12 and the software of the newest version registered in the server 12 is push- transferred to the terminal 10.

Title: Optical reader
Inventor: YAZAWA JUNICHI
IPC: H04N1/028
Filed: 1988-10-11
Abstract: PURPOSE:To continuously change filter effect from zero to the maximum and to cope with all practical types of originals by tilting an optical low-pass filter whose phase parts are arrayed in the same direction at the same interval by a prescribed angle with respect to the optical axis of an image forming optical system in accordance with the periodicity of an original. CONSTITUTION:The optical reader is provided with the low-pass filter 1 whose phase parts are arrayed on both sides of a transparent substrate in the same direction at the same interval. Whether the low-pass filter 1 is at a right angle with respect to the optical axis 2 of the image forming optical system, or tilts a prescribed angle, the same luminous flux transmitting the optical low-pass filter 1 may transmit the phase part or non-phase part according to the angle. Accordingly, the phase difference of the entire transmitting luminous flux comes to zero or the maximum. In such a way, the phase difference of the transmitting luminous flux varies continuously from zero to the maximum with a change in the angle.

Filed: 1987-10-09
Abstract: PURPOSE:To transmit the rotation of a motor to a pickup via a driving mechanism and to simplify the mechanism of the title player by displacing a pressing member to a 2nd position in its sliding to a tray housing position, pressing the pickup due to this displacement and displacing the pickup a little accordingly. CONSTITUTION:A disk is placed on a tray 1 and a motor 7 is rotated. The tray 1 is slid by a gear 12 via a gear mechanism in the direction of C. Just prior to the housing position, an end of a rack 13 is brought into contact with a tongue 19a of the pressing member 19, so that the member 19 is displaced into the 2nd position. A hook 19c is disengaged from a protrusion 20 of a rack 18, and hence a tongue 19b presses the protrusion 20 to slide the pickup 4 slightly in the direction of F, and then the sliding is kept on by the motor 7, and when the pickup 4 reaches the innermost circumference of the disk, the motor 7 is stopped by a switch. Afterward, the motor 7 is brought under the rotating state corresponding to the sliding direction of the pickup. By an ejecting operation, the movements are performed in the reverse sequence to enable the disk to be loaded or unloaded at a mounting part 1a. By this constitution, the structure can be simplified by using a single motor.

Filed: 1986-10-29
Abstract: PURPOSE:To erase noise components and to obtain image information having an excellent S/N, by erasing the remaining noise image on a panel by means of an erasing means before picture formation is made after power supply. CONSTITUTION:Rod-like erasing lamps 15 are provided in the direction vertical to the sub-scanning direction (shown by the arrow Y) on the side of a light condensing body 13 opposite to the sub-scanning direction Y and a remaining latent image is erased by projecting intense light to a panel 1. When a unit 5 moves to the direction opposite to the scanning direction Y, the erasing lamps 15 are turned on in the midway of the movement and all of the images remaining on the panel 1 or noise components produced by the background, etc., while this image reader is kept untouched for a long time are erased. When the unit 5 reaches its uppermost position, exposure to radiant rays is performed and a latent image is formed on the panel 1. After the latent image is formed, the unit 5 moves to the direction Y and the radiation image produced by the exposure is read by two-dimensional scanning. Therefore, the S/N in image reading is improved and more correct image information can be obtained.

Title: Disk device
Inventor: MURAOKA OSHI
IPC: G11B7/125
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To improve the recording quality by controlling the output level for the recording of a disk device. SOLUTION: A recording/reproducing head 1 is seeked to an empty region of a disk 2 and recording data are packet recorded by driving laser light beams, which are adjusted at a set recording power. Then, discrimination is made to determine whether the recording data to be recorded are completely recorded or not. If there exist remaing data to be recorded, a comparison is made between the number of blocks in which recordings are completed, and a prescribed value (N). If the number of blocks, in which recordings are completed, satisfies the value (N), the recording is interrupted, a reproducing is made for a prescribed region of the packet, in which a last recording is made, an upper peak level (RFDC+A1), a lower peak level (RFDC-A2) and an average d.c. level (RFDC) are obtained and given to a CPU 10. Then, in the CPU 10, a β value is computed.  If the β value is a positive value, the value, which is obtained by subtracting a prescribed value ΔP from the recording power prior to the interruption of a recording, is set as a new recording power (Pwo). If the β value is negative, the value ΔP is added to the recording power prior to the interruption of the recording operation and is set as a new recording power (Pwo).
