Title: Control system for multi-joint robot
Inventor: IWAKAWA SHINJI
IPC: B25J9/10
Filed: 1985-04-23
Abstract: PURPOSE:To detect accurately the present posture of a working terminal by using a detecting means to detect the relative displacement degree of each axis of a working shaft and calculating the displacement degree of an absolute coordinate system from said relative displacement degree and the output of another detecting means. CONSTITUTION:The potentiometers P1-P3 are attached to DC servo motors M1-M3 which drive an arm 10 of a multi-joint robot. The position information (relative angle displacement degrees) given from the potentiometers P1-P3 are given to a gear interference arithmetic circuit 21. The circuit 21 gives the position information (absolute displacement degree) with which the gear interference is calculated to a multiplexer 22 and a working area setting comparator 23. A control part 24 applies a shaft switching signal l3 to the multiplexer 22 via a photoisolator 25. Then the multiplexer 22 supplies the joint position information to the part 24 as the designated position information via an A/D converter 26 and the isolator 25. Thus it is possible to obtain the position information that canceled the moving interference of each joint.

Filed: 1981-06-05
Abstract: PURPOSE:To compensate the temperature characteristic and the secular change of optical constituting elements which give no disturbance to a system to be measured, by using two polarizing films, namely, a movable polarizing film and a fixed polarizing film.

Title: Developing method by magnetic brush
Inventor: OKAMOTO YOSHIKAZU
IPC: G03G15/09
Filed: 1980-06-30
Abstract: PURPOSE:To perform satisfactory developing by performing developing in a repulsive magnetic field by the use of a developer consisting of small size magnetic carriers of 5-30mu and toner particles and a developing roll which rotates a sleeve with internal magnets fixed therein. CONSTITUTION:A developing roll 13 mounted with a pair of magnets 12, 12 with their polarities faced in the same direction is provided in a rotary sleeve 11 in opposition to a latent image holding and recording body 10. The developer used is a two component developer of a small size carrier of 5-30mu average grain sizes and a toner. This constitution widens the contact width of earing and the body 10 on account of the repulsive magnetic field by a pair of the magnets 12. Since the small size carrier weakens the coupling between particles, the developer density is rough and the movement of the toner particles in a circumferential direction is less blocked by the carrier; hence, the toner sufficiently sticks on the body 10. Since the circumferential movement force of the carrier is strong, the sticking on the peripheral parts of the image is less and good developing is accomplished.
