Title: Control system for pulse train input type digital servomotor
Inventor: SAGARA YUJI
IPC: B25J9/16
Filed: 1985-10-31
Abstract: PURPOSE:To design the access time of a main arithmetic unit which generate command pulses to tens of milliseconds and to reduce the load by controlling acceleration/ deceleration control over a servomotor with burst-shaped command pulses generated at predetermined intervals. CONSTITUTION:Pulses whose number is proportional to the quantity of movement expected within a unit time are distributed and supplied to an error counter 23 which constitutes what is called a servo-motor control circuit with a pulse train which is supplied separately at a fast pulse rate at pulse intervals much smaller than the unit time. The pulse distribution to this error counter 23 is carried out repeatedly by as many times as movement time specified in every unit time. Nonsynchronous circuits 21 and 22 calculate differences between feedback pulses from the encoder 27 and pulses shown in figures D and E and the cumulative value of pulse outputs of the differences is a speed command. Consequently, smooth acceleration/deceleration control is performed by commanding the movement quantity and time in plural stages at intervals of tens of milliseconds even during the acceleration/deceleration control and the main arithmetic unit only attains access at intervals of tens of milliseconds and its load is reduced greatly.

Title: Ultrasonic wave generation circuit
Inventor: IKUTA HIDETSUGU
IPC: G01N29/26
Filed: 1984-11-16
Abstract: PURPOSE:To generate a burst wave fast in the rising and falling with a small pulse length, by feeding a relatively long burst wave generated with a sine wave oscillator to a shaping circuit adapted to gate according to a pulse contained in the pulse period of a shaped pulse. CONSTITUTION:A burst wave with a relatively long pulse length generated with an oscillator at the preceding stage is inputted into a shaping circuit D. Anode of diodes 14 and 16 of a circuit D are biased DC to the zero potential with choke coils 13 and 19 and with the application of a reverse bias, it is turned OFF. The anodes are turned ON with the application of a forward bias as the shaped pulse EP from a terminal 18 enters the pulse period and exceeds V1. Then, as coils 13 and 19 have a high impedance with respect to a high frequency, a burst wave is outputted corresponding to the pulse period of the pulse EP from an output terminal 20. Thus, the diodes switched according to the pulse EP with a small pulse width to obtain a burst wave with a short pulse length.

Abstract: PURPOSE:To prevent the generation of noise through collision by stopping the output body of a drive unit not by the collision with a stopper but by the attractive force by magnetic force. CONSTITUTION:The pole parts of an electromagnet is provided at an interval that it can oppose a pair of magnets N and S, consequently in case that the magnetisms arising at pole parts 40a and 40b by the excitation of the second electromagnet 4 become, respectively N and S combinations with the polarities of one pair of magnets 7 and 8, the magnetic parts and the magnets attract each other, and an output shaft 2 shifts so that both may get in opposed conditions. And in this condition, the current application to the electromagnet is stopped, and the output shaft is held at that position. Next, the first electromagnet 3 dislocated is excited so that the pole parts 30a and 30b may have the magnetisms of attracting other one pair of magnets 6 and 7 with each other, whereupon by both attractive forces, the output shaft shifts in the reverse direction so that both may be opposed to each other. The shift and stoppage of the output body is done by the attractive force by the magnetic force this way, the generation of the collision noise can be prevented.
