Title: Robot control method
Inventor: MIYAZAKI TOMOHIRO
IPC: B25J9/10
Filed: 1991-06-12
Abstract: PURPOSE:To equalize the position of an end effector to a command value without error by obtaining the command of a joint, which mainly controls the position of an end effector, based on the command value of a joint, which controls the attitude of the end effector, and the command value of the position. CONSTITUTION:Command values of the position and the attitude of an end effector 46 in a present control period, namely, position coordinates of the origin of hand coordinates 61 and direction vectors of (x), (y), and (z) axes are calculated. When hand coordinates 61 are determined, position coordinates of the origin of wrist coordinates 62 are easily calculated. Since position coordinates of the origin of wrist coordinates 62 are dependent upon respective displacements of first, second, third, and fourth joints, position coordinates PWX, PWY, and PWZ of the origin of wrist coordinates 62 are functions of theta1, theta2, theta3, and theta4. However, ternary simultaneous equations can be solved if the variable theta4 is known. Thus, command values theta1, theta2, and theta3 of first, second, and third joints are obtained.

Filed: 1980-11-29
Abstract: PURPOSE: To make mass production of products of the gorgeous feel having patterns in which copper skin appears by polishing and coloring the surfaces of copper products while holding paint stuck in the hollow grooves of the patterns worked on said surfaces.  
     CONSTITUTION: Patterns are pressed on the material of a saucer of copper or a copper plate metal by using dies engraved with characters or pictures, and gaseous, liquid or powder paint is stuck on the surfaces of the patterns, after which it is dried. After the drying, the paint is stripped by polishing to expose the skin of the copper. However, the paint films stuck in the hollow grooves 2 of the patterns remain perfectly without polished. Hence, in spite of putting the polished material into coloring liquid, the exposed parts of the copper skin are colored but the grooves 2 do not make chemical reaction and the parts of the patterns retain the red color of the copper. This is molded to a saucer which is product. In the patterns 3 thereof, the copper skin of the feel engraved with chisels appears and this provide a look of high grade, and since mass production is possible, the cost of production is reduced.

Filed: 1984-08-11
Abstract: PURPOSE:To exhibit discharging function of pump even in low and intermediate vacuum region by inclining the wall face of groove which will face in the opposite direction from the advancing direction through rotation thereby increasing the probability of collision of gas molecules against the static and dynamic wall faces which will exhibit pumping function. CONSTITUTION:The rear wall face 11 directing in the opposite direction from the rotary direction of dynamic groove 8 is inclined against the axis toward the static wall face 2. Conseqently, the probability of molecules collided against the rear wall face 11 to collide against the static wall face 2 will increase. Since the molecules colliding against the front wall 10 after collision against the static wall face 2 is effectively energized of the speed vector component in the direction of delivery port 4 through collision against the front wall 10, the probability of collision against the static wall 2 is increased. Consequently, the discharging function per unit area of the front wall face 10 is augumented to improve the discharging capacity of molecular pump as a whole. As a result, the discharging function in delivery function per single groove can also be augumented to enable usage from low to intermediate vacuum region.

Abstract: PROBLEM TO BE SOLVED: To obtain a high frequency power supply suitable for fine machining by constituting the inverter in the power supply of a plurality of arms each having a series connection of a plurality of high speed semiconductors thereby decreasing the power supply reactor determining the maximum output. SOLUTION: An on/off signal from a laser control circuit 17 is converted through an optical oscillator 18 into light which is transmitted through an optical fiber 20 to a gate circuit 14. The gate circuit 14 is previously supplied with power from a gate power supply 15 and provides a gate signal to a high voltage switch 13. A high voltage power supply 16 is divided into two and the neutral is grounded. Since the high voltage switch 13 switches high voltage directly, no booster transformer is required and the inductance from the output end of a full-bridge inverter to a load substantially depends on an output reactor 12 to be inserted. Since a sufficiently low output reactor 12 can be selected, inverter frequency can be increased resulting in the increase of discharge power and laser output strength.
