Title: Horizontal multi-joint robot
Inventor: KUWABARA MASAYUKI
IPC: B25J17/00
Filed: 1987-12-02
Abstract: PURPOSE: To constantly maintain the attitude of a tool fitted to a tip of an arm without applying correction for control to a motor by fitting a brake, which can freely rotate and can not advance straight, to a shaft having a screw part provided in a tip and a spline part on the same core. CONSTITUTION: A motor 17 for linear shaft is non-electrified at the time of direct teaching, and a ball screw and nut 3 is rotatably set, and arms 11, 12 are moved so that a screw spline shaft 1 is rotated with the rotation of a ball spline nut 5 and that it can not linearly advance. At the same time, a brake 7, which can rotate but which can not linearly advance is operated so as to hinder the generation of fall of the screw spline shaft 1. As a result, the screw spline shaft 1 only rotate similarly with the ball spline nut 3, and the attitude of a tool 2 fitted to the screw spline shaft 1 is constantly maintained independently of the operation of the arms 11, 12 at the time of direct teaching.

Title: Optical character reader
Inventor: KURITA MASAO
IPC: G06K9/34
Filed: 1989-11-22
Abstract: PURPOSE:To enable the satisfactory detection and segmentation processing of a character similarly to a normal processing by erasing the image of an underline or a ruled line on an image buffer when the underline or the ruled line is attached to the character on a slip. CONSTITUTION:A detecting means 4 detects the image of the underline or the ruled line attached to the character from a slip image stored onto an image buffer 2. An erasing means 5 erases the detected image of the underline or the ruled line from the image buffer 2. Thus, even when the underline or the ruled line is attached to the character on the slip, the detection and segmentation processing of the character can be satisfactorily executed similarly to the normal processing.

Title: Rear-wheel supporter for motorcycle
Inventor: YOSHIOKA TOSHIJI
IPC: B62K25/26
Filed: 1987-12-04
Abstract: PURPOSE: To make a rear wheel steerable and keep a caster angle constant by connecting a rear wheel hub in a bendable state to a drive shaft, and connecting a knuckle for supporting the rear wheel hub rotatably, to a bearing block so as to be bendable at two upper and lower points passing the center of the drive shaft. CONSTITUTION: A rear wheel hub 38 is connected in a bendable state to a drive shaft 31 supported to a bearing block 25 at the rear part of a swing arm 21 composed of two parallel upper and lower arm members. A knuckle 41 supporting the rear wheel hub 38 is connected to the bearing block 25 so as to be bendable at two upper and lower points A, B passing the center O of the drive shaft 31, through an elastic device 51 laid between them to provide a rear wheel 16 with a caster angle. As a result, trail is generated to the rear wheel 16, and the rear wheel 16 is steered by lateral force acting upon a tire grounding point. The horizontal vibration of the rear wheel 16 is absorbed and relaxed by the elastic device 51 to prevent wobble. The change of a caster angle of the rear wheel 16 is also prevented by the vertical motion of the swing arm so as to keep the caster angle constant.

Title: Manufacture of vibration proof device
Inventor: MIZUTANI TADASHI
IPC: B23K26/21
Filed: 1992-11-17
Abstract: PURPOSE:To provide a method for manufacturing a vibration proof device by which sufficient strength is imparted to a cylindrical member and the vibration proof device is efficiently manufactured. CONSTITUTION:A cylindrical part 14 is formed by bending/forming a steel plate into a cylindrical shape and the butted part 18 is joined by welding 26 from the outside by inert-gas arc welding. After that, a mounting arm is welded on the outer peripheral part astride the weld 26. Since the butted part 18 is welded at high strength by inert-gas arc welding, sufficient strength is imparted to the cylindrical part 14. Since the removing work of slag and residual flux after welding in common arc welding is unnecessary in inert-gas arc welding and spatter is hardly generated, the post-work after welding is drastically shortened and the vibration proof device is efficiently manufactured.

Title: Bus system and bus bridging system
Inventor: ONISHI KATSUYOSHI
IPC: G06F13/36
Filed: 1992-11-17
Abstract: PURPOSE:To transfer data without being conscious of a trunk bus in a hierarchical bus system consisting of plural branch buses and the trunk bus. CONSTITUTION:Plural branch buses 2 are connected to the trunk bus 1 through a bus bridge circuit BB. In the case that the data is transmitted/received between modules MD connected to the branch buses 2, the bus bridge BB of one side acts for the branch bus 2 of the other side, and the bus bridge BB of the other side acts for the branch bus 2 of one side. Thus, the branch buses are linked through the trunk bus 1. Accordingly, since the distant intrabranch buses are bus-linked equivalently as one branch bus, data format/bus protocol on the branch bus is preserved at the time of transmitting/receiving the data between the modules through the trunk bus. Bus capacity is increased by bundling bus links on the trunk bus.

Title: Secrecy keeping method for information transmitting system using optical information recording medium
Inventor: SATO SHUNICHI
IPC: G06F21/10
Filed: 1990-11-13
Abstract: PURPOSE:To enable a secret keeping method to function effectively in an information transmitting system using an optical information recording medium by making the reproduction of the information recorded on the recording medium possible only when a specific password code is inputted. CONSTITUTION:A prescribed password code is recorded in advance in the password code recording area 11 of an LD 10 and an optical disk compatible player 20 is constituted in such a way that the player 20 is not able to read out the other information in the LD 10 unless a password code inputted from a password code input device 30 coincides with the password code read out from the area 11. In other words, the player 20 can output the content of the LD 10 as reproduced signals only when both password codes coincide with each other. Therefore, this secret keeping method can function effectively in an information transmitting system using an optical information recording medium.
