Title: Position controller using feedforward compensation
Inventor: NAGAO YOSHINORI
IPC: G05B11/32
Filed: 1989-07-06
Abstract: PURPOSE:To improve the precision of a locus and to shorten positioning time by providing a feedforward loop including a dead time element and a 1st-order delay element at a velocity command part in addition to a position feedback loop. CONSTITUTION:A position control part is comprised of a position loop control part 1 and a feedforward compensation part, and the position loop control part 1 outputs a signal in which a position command from a host and the deviation of a position feedback value from a pulse generator 8 are multiplied by a position gain. The feedforward compensation part is comprised of a differentiation processing 2, a gain part 3, and the idle time element 4. The output signal of the position loop control part 1 is added on that of the feedforward compensation part, and is inputted to a D/A converter 5, and the D/A converter 5 inputs a converted signal to a velocity control unit 6 as a velocity command. The velocity control unit 6 decides the output voltage to the motor 7 corresponding to the velocity command, the differential value of position feedback from the pulse generator 8, and an output voltage from a current feedback value from a motor 7. Thereby, the high precision of the locus can be realized, and fast positioning can be performed.

Title: Mist generator
Inventor: IWASHITA HIROYUKI
IPC: B05B12/00
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To shorten the user's waiting time with a device which atomizes hot water and discharges mists by starting atomization after the prescribed time and making it possible to change the prescribed time when an operation switch for supporting the start of an atomizer is operated. SOLUTION: Whether the state of turning on a run switch 39 elapses the prescribed time, for example, >=2 seconds or not is judged in the case the inside of a bath room is foamed as a mist sauna. In the case of <2 seconds, a delay time timer is started and a motor 17 is started to generate the mists after the timer attains the prescribed delay time. The delay time is set in accordance with the time enough for the stagnating water in a supply flow passage 5 to be completely discharged by the supply hot water from a hot water supply source. At this time, the mists are generated by starting the motor 17 without providing the operation with the delay time in the case of >=2 seconds after the on of the run switch 39. The mist generation is stopped by stopping the motor 17 when the run switch 39 is turned on again.

Title: Method of reducing current down in synchronous equipment and circuit device
Inventor: IENSU HAMAN
IPC: H02P25/03
Filed: 1989-07-07
Abstract: PURPOSE: To prevent an angular moment from being collapsed by short-circuiting the high-frequency scanning voltage of triangular wave of the pulse frequency generator of the ignition control device in a converter for feeding a synchronous machine over one predetermined synchronization period of time at the point of time of respective starting commutation. CONSTITUTION: According to a synchronization method of a scanning voltage Ud , the scanning voltage Ud can be started in a positive slope or a negative slope at 0 volt when each commutation is started. When the commutation is started at the synchronization point of time tSR2 , the current of phase S is brought into off-commutation more rapidly as compared with the commutation at the synchronization point of time tSR1 . Therefore, different current collapse is generated in a phase R which is not concerned in the commutation. However, the current collapse has an equal amplitude at the time of each commutation start. Accordingly, the whole current or the ripple of an angular moment over a plurality of periods of the terminal voltage of a synchronous machine 2 is reduced.
