Title: Optimum acceleration/deceleration control system for servo motor
Inventor: KATO TETSURO
IPC: G05B19/416
Filed: 1991-06-10
Abstract: PURPOSE:To extremely shorten the acceleration/deceleration time and then to shorten the recycle time by controlling automatically the acceleration of an acceleration/ deceleration control part in accordance with a target velocity in order to secure the maximum workable torque. CONSTITUTION:The acceleration of an acceleration/deceleration control part is calculated when a velocity-acceleration curve Ac obtained by subtracting a kinetic friction component from a torque curve of a servo motor touches the velocity-acceleration curves (Lc, L) of the answer of the motor given to a movement command. Based on the calculated acceleration, the acceleration/deceleration control is carried out. Under such conditions, the acceleration alpha has the optimum value when the velocity- acceleration curve is obtained between a curve Lc and a straight line L. That is, the maximum workable torque of the motor is secured with the curve Lc and the line L. Then the maximum acceleration alpha is secured for the acceleration/deceleration control part with no follow-up delay caused with the motor. When the acceleration alphais decided, the acceleration time (number Q of registers) T1 of the acceleration/ deceleration control part is obtained as V0/alpha from the target velocity V0 and the acceleration alpha.

Title: Manufacture of semiconductor element
Inventor: SAITO TADASHI
IPC: H01L29/86
Filed: 1986-07-16
Abstract: PURPOSE:To form a GaAs IC having a resistance element including a desired resistance value with good reproducibility by sorting a substrate having a resistance element of a smaller resistance value than the desired resistance value, selectively ion implanting to the element, and then annealing it at a specific temperature. CONSTITUTION:After a resistance element of an active layer 2 is formed, since the element is selectively ion implanted to a substrate 1 having the element of smaller resistance value than a desired resistance value, a lattice defect occurs in a resistance element region. Further, after ion implanting, it is annealed at 300-400 deg.C to eliminate a point defect existing sufficiently separately in a crystal. Thus, the element having a desired resistance value can be obtained with good reproducibility, and remarkable deterioration does not occur in the characteristics of an IC.

Title: Modulation system
Inventor: MURATA EIICHIROU
IPC: H04L27/12
Filed: 1978-12-25
Abstract: PURPOSE:To facilitate the switching between the FM modulation and the multi- phase modulation by providing the mixer for frequency compounding into the phase lock loop. CONSTITUTION:When change-over switches Ba and Bb are connected as shown in the diagram, the signals sent from multi-phase oscillator 1 are fixed to one standard signal via phase selection circuit 2 to be thus used as the reference signal of the phase lock loop. At the same time, the FM modulation is applied to the output signal of VCO5 by the input signal applied to modulator 10 and via terminal 15. In case the change-over switches are connected in the opposite position to the diagram, modulator 10 features the non-modulation state. And thus the signal given from oscillator 11 is supplied to mixer 7 in the form of the frequency compounding reference signal which gives conversion to the signal sent from VCO5 to the signal frequency to be supplied to phase detector 3. Furthermore, the multi-phase conversion signal input applied to terminal 14 is added to phase selection circuit 2, and thus the multi-phase modulation is applied to the output signal of VCO5.
