Abstract: PURPOSE:To always a drive an oscillator in its resonance frequency with a simple structure by detecting the phase difference between the signal applied to a laminated- type piezoelectric actuator and the detected signal from a laminated piezoelectric element for changing the frequency of the applied signal. CONSTITUTION:A piezoelectric element 7 is laminated together with a laminated-type piezoelectric actuator 2 in the inside of a housing 1, and the frequency of the signal to be applied to the actuator 2 is regulated by a voltage/frequency conversion circuit. And the phase difference between the signal applied to the actuator 2 through the voltage/frequency conversion circuit and the detected signal of the piezoelectric element 7 is detected by a phase difference detecting means for converting the voltage to that corresponding to the phase difference, and the voltage/frequency conversion circuit is controlled by a control circuit for changing the frequency of the signal to be applied to the actuator 2 so that the voltage corresponding to the phase difference is equalized to the voltage corresponding to the phase difference at the resonance point of an oscillator which has been previously obtained. As a result, the oscillator can be driven in its resonance frequency, and since the respective piezoelectric element are connected in parallel by using the laminated-type piezoelectric actuator 2, a lager displacement can be obtained in a lower voltage.

Title: Driving circuit for liquid crystal panel
Inventor: GOMI TAKESHI
IPC: G09G3/36
Filed: 1990-08-08
Abstract: PURPOSE:To prevent an irregularity in brightness from occurring by making the positive power source of a gate-side control circuit low in a negative polarity field. CONSTITUTION:The positive power source of the gate-side control circuit 7 is switched in voltage value in synchronism with a video signal which is inverted in phase field by field, by the input of a clock signal which is switched by bertical synchronism to a voltage switching circuit 13, and its voltage is outputted to the gate-side control circuit 7. Thus, the positive power source of the gate-side control circuit 7 is switched in synchronism with the position inversion of the video signal, so the potential difference in the negative polarity field becomes small and a normal image is displayed even at a distance from the gate-side control circuit 7. Consequently, the irregularity in brightness under the influence of the resistance of a gate line can be eliminated.

Title: Friction damper mechanism
Inventor: MAKISHIMA SADAO
IPC: F16F15/139
Filed: 1984-10-05
Abstract: PURPOSE:To eliminate the need of a space for installing a damper mechanism by dividing the hub of a synchronizer mechanism into two parts, providing a friction washer in between the both hubs, and incorporating a damper mechanism in said synchronizer mechanism. CONSTITUTION:Both hubs 5a, 5b have friction faces in the axial direction respectively, and a friction washer 6 is interposed between the faces. And, a coned-disk spring type spring 7 is interposed between the hub 5a and the large diameter part 22a of a driven main shaft 22. Thereby, when a driving force is applied to the hub 5a side, or when variation in load takes place on the hub 5b side, these hubs 5a, 5b can mutually slide via the friction washer 6 and, therefore, vibration caused by variation in torque can be absorbed here, displaying a damper effect. Accordingly, any particular space for installing a damper mechanism can be eliminated.
