Title: Finishing method of polygon mirror and device thereof
Inventor: TAJIMA TAKUJI
IPC: B23B5/00
Filed: 1984-01-25
Abstract: PURPOSE:To finish a polygon mirror in a highly accurate manner, by making the polygon mirror, being set up in paralleling its axial center direction to the surface of a rotary disc provided with a tool, rotate for indexing by the specified angle intermittently, while feeding the tool in an orthogonal direction to the mirror's axial center. CONSTITUTION:Two tools 17 for both roughing and finishing are clamped on a face plate 16 locked to one end part of a support shaft 15, and a polygon mirror 2 is rotated by the specified angle via a support shaft 14 and a vacuum chuck 49. When the polygon mirror 2 is fed forward to the tool 17 by means of a table feed mechanism 43, positioning for the mirror 2 in an orthogonal direction to a surface of the face plate 16 existing in the feed direction of the mirror 2 in relation to the tool 17 is determined whereby the mirror 2 is processed for finishing in the orthogonal direction to the axial center with rotation of the tool 17 so that even when cutting marks are produced, it is identical with the scanning direction of an incident laser beam and since a reflection factor is not varied at all, quality deterioration due to a difference between light and shade to be appear on the outer surface of a sensitive drum is thus prevented from occurring.

Title: Robot system
Inventor: KOYAMA TOSHIHIKO
IPC: B25J13/00
Filed: 1995-01-25
Abstract: PURPOSE: To improve the safety of a worker in a robot system put in action in connection with an external device. CONSTITUTION: After the action end of a robot body 100, interlock signal waiting time until the input of an interlock signal from an external device 300 for preparing environmental conditions for the action of the robot body 100 is counted. In the case of being within a minute, the action of the robot body 100 is executed at the specified action speed, and in the case of exceeding one minute, the action speed of the robot body 100 is changed to the slower speed than the specified action speed to execute the action of the robot body 100. When the input of the interlock signal is delayed and the execution of action is started even if a worker is near the robot body 100, since the robot body 100 starts moving slowly, the worker can go away from the vicinity of the robot body 100 so as to be able to secure safety.  Since the robot body 100 does not stop even if the input of the interlock signal is delayed, processing such as restart is not required so as to reduce the burden of the worker.

Title: Processing system of radar signal
Inventor: HASEGAWA MASANOBU
IPC: G01S7/292
Filed: 1987-01-19
Abstract: PURPOSE:To hold down the occurrence of a false symbol on an indicator and to improve the problem of system down, by providing a means not to deliver the data only of a primary radar when the false number of the primary radar exceeds an allowance. CONSTITUTION:This system is composed of a primary radar 1, a secondary radar 2, a target counting unit 6, a false determination unit 7, a data control unit 8 and a radar processing system 4. The counting unit 6 counts one by one how many target data exceeding a threshold set in a digitizer 13 are present in each area set separately. The determination unit 7 collates the data of the counting unit 6 with that of a correlation processing unit 3 to take only a false out of these data except a true target part, and compares it with a standard state of operation of the radar 1. In the case when the false of an area is more than a value set beforehand, the data control unit 8 removes the data only of the radar 1 in the same area sent from the processing unit 3 and delivers to the system 4 the data only of the radar 2 or the data which are correlated between the primary and secondary radars.

Title: Magnetic disk device
Inventor: NISHIMOTO HIDEKI
IPC: G11B21/21
Filed: 1988-01-20
Abstract: PURPOSE:To prevent the contact of a head and a disk surface even when the disk is stationary and to maintain a gap between the head and the disk surface when the disk is rotated by providing an piezoelectric substance which drives the other end side of a head spring to push the head to the disk surface when voltage is impressed. CONSTITUTION:The head spring 3 is usually fixed to a head block 4 in a state that the head 2 is previously floated from the disk 1. The piezoelectric ceramic 5 is situated between the head block 4 and the head spring 3 and fixed to the head spring 3. When the voltage is impressed on the ceramic 5 after charging a powersource, the ceramic 5 occurs displacement by piezoelectric effect, lowers the head 2 by pushing down the head spring 3 in this displacement part and pushes it to the surface of the disk 1. As the result of that, the same pattern when the head is floated by the viscosity of air is made. Thus, wearing phenomenon between the head and the disk at the starting time of the disk can be prevented.

IPC: F41G3/26
Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To facilitate correction work by a system wherein an operator swings his head such that information projected to a see-through type HMD matches information projected to a large projector while fixing the see-through type HMD and a three-dimensional measuring unit and searches a correcting position. SOLUTION: An operator 6 matches a cross reticle 14 presented at a projector display section 4 and a cross reticle on a screen generated by a see-through type HMD 7 by turning the head up/down and to the left/right. Under a state where both cross reticles are matched, the operator 6 pushes an attitude angle information reset button 9 provided in the see-through type HMD 7 to deliver a correcting position determination command to a computer 2. Upon receiving the command, the computer 2 registers the attitude angle at that moment as a reference attitude angle. More specifically, the computer 2 executes a specified processing to turn off a correction decision flag and executes registration processing.

Title: Corner position detector
Inventor: ITO KENJI
IPC: G01B11/00
Filed: 1987-01-20
Abstract: PURPOSE:To detect a corner position of a sheet type material more clearly by setting the scanning direction of a detection camera which incorporates a linear solid-state image pickup element so that it crosses both directions of two axes on the surface of a placing table. CONSTITUTION:A scan is made by the detection camera so as to detect the corner part of the sheet type material 2 which is placed and fixed on the table. At this time, the linear solid-state image pickup element slants in a direction A-B, i.e. to the X and Y axes to some extents to cross both directions of the two X and Y axes. Then while the scanning in the direction A-B is repeated, the element is moved from A-C. In this case, even when corner sides of the corner part of the material 2 are placed nearly in parallel to the X and Y axes, scanning lines of the linear solid-state image pickup element cross two sides constituting the corner of the material 2 to detect the corner position more accurately.

Title: Catalyst for carbonic acid ester production, reproducing method thereof, and carbonic acid ester production
Inventor: KOYAMA TAKESHI
IPC: C07C69/96
Filed: 1994-01-05
Abstract: PURPOSE:To provide high conversion efficiency into an alcohol even in a reaction initial stage at the time when a carbonic acid ester is produced by reaction of an alcohol and CO and O2 in the presence of a catalyst by carrying a copper halide and a carbonate salt on a porous carrier as a catalyst for carbonic acid ester production by oxidation-carbonylation of an alcohol. CONSTITUTION:A copper halide and a carbonate salt are carried on a porous carrier to give a catalyst for carbonic acid ester production by oxidation- carbonylation of an alcohol. In a method to produce a carbonic acid ester by reaction of an alcohol and CO and O2 in the presence of the catalyst, an alcohol and CO and O2 are reacted in gas-phase reaction conditions. As a result, the catalyst production process is simplified as compared with a conventional production process and a catalyst consisting of oxidized copper halide for carbonic acid ester production is obtained at high yield. A carbonic acid ester is produced highly selectively by utilizing the catalyst in highly active conditions. Also, since the production of a corrosive gas such as methyl chloride, etc., is suppressed to extremely low level, no noble substance is needed as a material for a reaction apparatus.
