Title: Control method for industrial robot and device thereof
Inventor: FUKUDA AKIRA
IPC: B25J13/08
Filed: 1994-02-07
Abstract: PURPOSE:To concurrently attain high acting locus precision and high maneuverability by detecting the state that the driving torque exceeds the critical torque, and changing the interpolating cycle based on at least the driving torque determined based on the action target data and the critical torque in response to the detection of this state. CONSTITUTION:When the calculated necessary torque is judged to exceed the critical torque, the interpolating cycle is changed in step SP8, and whether the interpolating process is completed or not is judged in SP9. If the calculated necessary torque does not exceed the critical torque in step SP7, the judgment of step SP9 is immediately made. When the interpolating cycle is changed, the zone where maneuverability is reduced corresponds to only the interpolated coordinate value judged that the necessary torque exceeds the critical torque, thus the reduction of maneuverability can be suppressed to the minimum required, and high acting locus precision and high maneuverability can be concurrently attained.

Title: Controller for induction motor
Inventor: MIZOGUCHI SHOJI
IPC: H02P23/20
Filed: 1990-01-24
Abstract: PURPOSE:To produce same torque with minimum primary current amplitude vector by a method wherein an exciting current component regulating means modifies the exciting current component command value so that the ratio between a torque current component command value and the exciting current component command value will be 1 and feeding back thus modified exciting current component command value. CONSTITUTION:A speed command N* and an actual speed N are compared 4, and if the difference  N is within a predetermined range a judgment is made than an induction motor is operating steadily. A torque component current command iq* is divided by an exciting component current(=M.id*) including a coefficient M to obtaining a ratio which is then inputted to a comparator 6 for comparing upper and lower two values. If the absolute value of thus obtained ratio is lower than 1, the comparator 6 produces a positive value which is then multiplied 7 by the output from the comparator 4 and integrated 8. When the integrated value is subtracted from the flux command value phi, outputted from a flux setter 2, id* decreases to increases the ratio. When the absolute value of the ratio is higher than 1, the comparator 6 outputs a negative value thus blocking decrease of id*. In such a manner, the ratio is substantially controlled to 1. By such arrangement, the induction motor is operated at constant speed with high efficiency during light load steady operation and a high output can be produced automatically even during transient operation, i.e., acceleration or deceleration.

By such arrangement, loss can be reduced and rectifying effect can be enhanced as compared with a conventional diode. A second current detecting circuit 12 and a second gate drive circuit can also perform similar operation.

Title: Focusing mechanism and optical head
Inventor: YOKOYAMA OSAMU
IPC: H01S5/00
Filed: 1989-01-24
Abstract: PURPOSE:To allow the position of an image point to be moved while a lens consisting of a diffraction grating structure is held fixed and to shorten access time by constituting the above mechanism of the above-mentioned lens and a light source which varies the oscillation wavelength by a wavelength varying means provided on the outside of a semiconductor laser. CONSTITUTION:The lens, such as micro Fresnel lens, having the diffraction grating structure is moved in the position of its image point in the optical axis direction by the wavelength of incident light. For example, the light from the semiconductor laser 101 is assumed to be condensed to the image point 103 if the wavelength of this light is the same as the design wavelength of the micro Fresnel lens 102. The image point 104 of the light of the wavelength shorter than the design wavelength moves in the direction parting from the lens if the above-mentioned light is assumed to be made incident on such micro Fresnel lens from the semiconductor laser 101. Conversely, the image point 105 moves in the direction proximate to the lens if the light of the long wavelength is made incident. The position of the image point is, therefore, changed by combining the light source of the variable oscillation wavelength and the lens having the diffraction grating structure and varying the oscillation wavelength of the light source. The access time is shortened in this way.
