Title: Space optical transmitter
Inventor: SHIRATAMA KOUICHI
IPC: H04B10/118
Filed: 1993-07-23
Abstract: PURPOSE:To make the entire transmitter small with respect to the space optical transmitter having a function of outputting a transmission optical beam having an offset angle with respect to a reception optical axis. CONSTITUTION:A subtractor circuit 6 subtracts a detection signal from an optical tracing sensor 2 sensing an angle deviation of a reception optical axis from a transmission beam offset angle data. A biaxial beam deflector drive circuit 3 controls a deviation angle of a biaxial beam deflector 4 based on an output signal from the subtractor circuit 6. Thus, a reception optical axis is corrected so that the light is made incident in a predetermined position of the optical tracing sensor 2 and the transmission light with an optical axis resulting from compensating an offset angle on the reception optical axis based on this transmission beam offset angle data is outputted from the biaxial beam deflector 4.

IPC: G05B19/404
Filed: 1986-08-29
Abstract: PURPOSE:To decide the position of a robot to an object with high accuracy by using a camera and a vision system that recognize a standard point for the object. CONSTITUTION:A robot control part 5 actuates a robot main body 1 under the control of an off-line program system of a CAD/CAM to decide positions of arms 3a and 3b or an end effector 4. In this case, a camera 6 is set near the end effector 4 to pick up the image of the object and sends it to a vision system 7. The system 7 analyzes the image picked up by the camera 6 and recognizes the relative position relation of the main body 1 between the effector 4 and the object. If a position shift, etc., are detected, the result of this recognition is sent to the part 5 for correction of the control carried out by an off-line program of the part 5. In such a way, the position shifts of the robot 1 itself and the object are corrected and the position of the robot 1 can be decided to the object with high accuracy.

IPC: G11B5/842
Filed: 1987-08-13
Abstract: PURPOSE:To ensure stable and sure perpendicular orientation and to smooth the surface of a magnetic layer by subjecting the magnetic particles in the undried magnetic layer to a perpendicular orientation treatment by the perpendicular magnetic field penetrating said layer, applying a specific change of the magnetic field direction thereto and declining the magnetic field intensity. CONSTITUTION:The drying of the undried magnetic layer on a nonmagnetic base is progressed and after the coated magnetic layer is dried to about the extent at which the magnetic particles are substantially not turned at the terminal of a perpendicular orientation device, and acclimatization stage is started. The magnetic layer is completely dried at the terminal of said stage or in the drying stage connected thereto at need. The magnetic field direction is changed by 45-180 deg. with the dried and uncompleted magnetic layer formed with the magnetic poles in the magnetic particles subjected to the powerful perpendicular orientation treatment in the acclitimatization stage and the magnetic field intensity is gradually weakened toward the direction where the web is conveyed. The magnetic poles on the surface of the magnetic layer are thereby erased and the roughening of the magnetic layer surface is prevented. The stable and sufficient perpendicular orientation is thereby ensured.

Title: Controller for electric railcar
Inventor: HIRAMATSU YOSHIHARU
IPC: H02P3/14
Filed: 1983-10-27
Abstract: PURPOSE:To enable to obtain a desired brake force in a high speed range without increasing main circuit devices by utilizing a main resistor used in a power drive mode as a brake resistor. CONSTITUTION:When a regenerative brake is applied in a range of a speed V0 of higher, cam switches R17 and R11-R14 are closed to insert a portion designated by the symbol R of a main resistor MR in series with an armature A. When the regenerative brake is applied in this state and the speed of an electric railcar decreases lower than the V0, it closes a cam switch R15, then closes the switch R17 to form a circuit to which a series resistor is not inserted. Thus, brake characteristic can be improved without increasing the device mounting space.

Title: Aperture type area gas discharge lamp
Inventor: SATO YOSHINORI
IPC: H01J61/35
Filed: 1986-08-29
Abstract: PURPOSE:To prevent the strength of the light discharged through a slit section from being dispersed in the axial direction by making the width of an outer electrode smaller than the width of the slit section of a light shielding film. CONSTITUTION:The width W1 of an outer electrode 5 is made smaller than the opening width W2 of a slit section 7 formed with a light shielding film 6. According to this constitution, a positive column A is pulled toward the outer electrode 5 side to approach a tube wall during lighting, hut the width of the outer electrode 5 is formed small, thus the meandering width of the positive column A is made small. As a result, the positive column A is prevented from being largely protruded from the width of the slit section 7. Accordingly, a phosphor film 2 positively facing the slit section 7 is strongly illuminated, thus strong emission is discharged nearly uniformly along the axial direction, and the dispersion of light distribution characteristic in the axial direction can be dissolved.
