Title: Optical disk device
Inventor: BANSHO HIDENORI
IPC: G11B7/09
Filed: 1988-01-18
Abstract: PURPOSE:To improve the performance of tracking and focusing and to reduce the size and weight of the title device by fixing an optical disk and scanning an optical system. CONSTITUTION:The tracking and focusing of a laser beam radiated from a laser light source 1 are controlled by an optical system 2. At the time of penetrating into the 1st cylindrical diffraction grating 9a rotating in an arrow 11 direction, the laser light is vertically oscillated, and at the time of penetrating into the 2nd cylindrical diffraction grating 9b rotating in the arrow 11 direction, oscillated right and left. The oscillated reading laser beam is reflected by a mirror 11 and vertical made incident upon a pit 4 of an optical disk 10. Since the whole length of an optical path is fixed in a scanning process, the optical system 2 and the gratings 9a, 9b can be moved in an arrow 8 direction. Since a signal recording face is not moved, tracking and focusing can be accurately executed, and since the rotation of the optical disk 10 is unnecessary, a rotating space and a motor or the like can be omitted and the size and weight of the device can be reduced.

Filed: 1994-01-26
Abstract: PURPOSE:To offer a slide mechanism which can be manufactured inexpensively with less manhours for being composed of only those parts that can be manufactured easily and which can maintain its a stable slide performance. CONSTITUTION:A slide mechanism 2 is mainly composed of an outer pipe 10, an inner pipe 20 and a pair or interposing member 30 A, 30B. A contraction section 14 discharges its part as a stopper section by stopping the inner pipe 20 inserted into a through hole 12 together with interposed members 30A, 30B from coming out of the through hole 12. By engaging the wind parts 38A, 38B of the interposing members 30A, 30B with each other at the engaging part sandwitching a burr of the inner pipe 20, the interposed members 30A, 30B do not slip out of the inner pipe 20 but slide together in one unit when the inner pipe 20 slides. Since the outer pipe 10, the inner pipe 20, the interposing members 30A, 30B and the like can be easily manufactured inexpensively with less manhours, the slide mechanism 2 which can maintain a specified and suitable slide resistance and can be manufactured inexpensively with less manhours, is realized.

Title: Packet relay control method
Inventor: YAMAMOTO HIROYUKI
IPC: H04L45/74
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To reduce useless relayings of packets to a registration system port by not performing relaying to the registration system port when a packet is not recorded in a data base. SOLUTION: Whether or not data transmission destination terminal address of a packet is recorded in the terminal address of a data base is retrieved. In the case a data transmission destination terminal address is recorded in the data base, whether or not a port number recorded in a set with the terminal address and the port number of a reception port match is checked. When they do not match, the packet is delivered to a recording port. In the case the data transmission destination terminal address is not recorded in the data base, the packet is delivered to all the remaining ports when the ports other than the reception port and the registration system port are present.  When the size of a frame to be relayed to the respective ports judged as suitable for relaying is on the outside of the allowable range of a data link layer protocol used in the respective ports, relaying to the port is not performed and abandoned.

Abstract: PURPOSE:To rotate a reversible drive means surely to a specified position by outputting a non-drive signal after the lapse of a specified time to a drive circuit from a timer circuit starting operation through a single shot pulse generated for every output of a driving signal. CONSTITUTION:When a belt driver stops a movement for some reason before it reaches a release position, H signals are outputted from all Q1-Q4 of a counter T1 by a timer circuit 6 after 15 seconds and an L signal is outputted from Q of a D flip-flop DF3 while said L signal is inputted to the gate of RS latch LT1 so that the RS latch LT1 is reset and a forward rotation drive circuit 7 reaches an undriven state to stop a motor 1. Thus, said timer circuit 6 outputs a reset signal to the forward rotation drive circuit 7 after the time is up so that unnecessary current can be prevented from flowing through the motor 1.

Filed: 1992-01-21
Abstract: PURPOSE:To move a plurality of sensors by one spherical motor by providing a plurality of sensors for controlling to move a normal line of a spherical gimbal to be rotated by the motor. CONSTITUTION:When a relative distance between a target and a missile is reduced and becomes a distance for sufficiently aiming at the target even by an infrared ray sensor 4 for an optical wave seeker, the sensor 4 is switched from a radio wave antenna 3 for a radio wave seeker to an infrared ray sensor 4 for an optical wave seeker, and a guiding system is switched to an infrared ray tracing system having an excellent aiming accuracy. That is, a spherical gimbal 2 is rotated by a spherical motor, and a control shaft is switched from a gimbal control reference shaft 5 for the radio wave seeker to a gimbal control reference shaft 6 for the optical wave seeker. Thus, high accuracy tracing is again continued by controlling to rotate the gimbal 2. In this case, since the antenna 3 and the sensor 4 are mounted on a peripheral surface of a direction having a different bearing angle to an axis of the missile, sensing failure does not occur.

Title: Drawing inputting device
Inventor: TABATA MITSUO
IPC: G06T1/00
Filed: 1980-01-28
Abstract: PURPOSE:To input efficiently drawing information by reading out and storing the position information of an image sensor according to the information of movement change points in a drawing inputting device which automatically traces the segments and boundary lines of drawing information. CONSTITUTION:When an image sensor 3 is in the position, a1, photoelectric transducers 4c, 4r, 4d, are OFF; therefore, the rightward movement is instructed and only the transducer 4u remains ON. When the sensor 3 reaches the position a2, the transducer 4r changes to ON; therefore, the sensor 4 is assigned of the downward movement. At the same time, the coordinate position of the position a2 is registered in a memory device 7. In this way, the tracking and movement of the boundary line of a square pattern A are accomplished. Hence, the accurate reading of the drawing information is accomplished and since there is no input of wasteful information, the memory capacity is decreased.
