摘要： PURPOSE:To facilitate the handling and maintenance of a substrate by a method wherein a wiring is electrically connected to an electronic circuit via wiring conductors buried previously in the substrate when the substrate is molded integrally with the electronic circuit. CONSTITUTION:A third projection substrate 55 is mounted under the lower part of a selecting lever 53 like first and second projection substrates 35 and 36 and is connected by soldering to each one end of wiring conductors L5 and L6 buried previously in a main substrate 20. Moreover, the other ends of wiring conductors L1 to L4 and the conductors L5 to L6 are made to project in a state that they are arranged in one column at prescribed intervals at the lower left corner of the substrate 20 and are provided in such a way that they can be connected to each other by a connector. A wiring to an electronic circuit mounted on the substrate 20 is provided via the wiring conductors L5 to L6 buried previously in the substrate 20 at the time of molding of the substrate 20. Thereby, a shaping of lead wires and a finishing work become unnecessary and the handling and maintenance of the substrate 20 are facilitated.

摘要： PURPOSE:To make a smooth start-up of a motor at all times by a method wherein the frequency of a.c. signals which are applied at the time of motor start-up is so swept that it may come near the resonance frequency of a piezoelectric body and the sweeping is stopped when the level of signals detected by a piezoelectric sensor gets larger than the specified value during sweeping. CONSTITUTION:When start up signals are inputted, the output of a start up timer 23 comes to the 'H' level. Therefore, the sweeping voltage of a start voltage Vs is inputted into VOC 30 from a voltage sweep circuit 24 and the frequency of a.c. signals applied to an ultrasonic motor M is swept toward the resonance frequency accordingly. Along with this, an elastic wave amplitude of the ultrasonic motor M increases and the level of signals detected by a piezoelectric sensor 6 increases, too. The actual rotation speed of the motor increases slowly. However, when the level of the signals detected by the piezoelectric sensor 6 exceeds a reference voltage Vr at time t2, the start-up sweep circuit 24 stops sweeping, keeping a voltage Vc inputted into the VCO 30 at a value Vp and the frequency of the a.c. signals applied to the ultrasonic motor M at a value fp.

摘要： PURPOSE:To provide a compact driving and controlling apparatus by installing a motor transfer switch for applying AC signals to an ultrasonic motor assigned to drive and also by performing a feedback control in such a manner that the rotating speed of the ultrasonic motor assigned to drive becomes closer to the speed corresponding to a reference voltage. CONSTITUTION:By transfer signals, if a reference voltage switch 25 is connected to the side of a variable resistor 26 and a motor transfer switch 36 is connected to the side of a motor M1, then the amplitude K1 of an elastic wave at that time is detected by a piezoelectric sensor 6, the oscillating frequency of a VCO 29 is converged into a predetermined frequency by a loop control, and the rotating speed of the motor M1 indirectly stabilized. On the other hand, if the switch 25 switch 36 are transferred to the side of motor M2, then the pulses from a rotary encoder 16 are output to a frequency and voltage conversion circuit 22, an oscillating frequency of the VCO 29 is converged to a predetermined frequency by the loop control, and then the rotating speed of the motor M2 is stabilized.
