Title: Ultrasonic oscillator
Inventor: KOJIMA NOBUYUKI
IPC: B06B1/06
Filed: 1993-12-01
Abstract: PURPOSE:To eliminate the need of a step for soldering a lead wire in the assembling process by inserting a large number of printed circuit boards requiring no soldering work between piezoelectric elements and oscillator bodies and fixing the printed circuit boards simultaneously with tightening of the piezoelectric elements and the oscillator bodies by means of a tightening bolt. CONSTITUTION:The ultrasonic oscillator comprises a piezoelectric disc 1, first and second oscillators 2, 3 made of a metal, a printed board 4 for feeding power to each electrode on the piezoelectric disc, an electrode plate 19 for bringing the common electrode 8 of the piezoelectric disc to GND potential, and a bolt 5 for tightening them. The piezoelectric disc 1 is disposed closely to the maximum distortion position of the oscillator. Since the printed board 4 is disposed contiguously to the piezoelectric disc 1, distortion due to deformation of the oscillator is increased. Consequently, a material having low damping characteristics is selected for the printed board. When a printed board is employed for feeding power to a piezoelectric element and the tightening structure of an oscillator is utilized, power can be fed conveniently and stably without requiring any troublesome work, e.g. bonding.

Title: Video signal switching device
Inventor: IKATA KOICHI
IPC: H04N5/91
Filed: 1988-11-30
Abstract: PURPOSE:To prevent the generation of a switching noise or skew by setting up the switching timing of a video signal within a vertical blanking in synchronism with the video signal. CONSTITUTION:A signal (d) from a switch 7 is inputted to the data input terminal D of a D-type flip flop circuit 11. The output signal (h) of the circuit 11 is outputted by synchronizing the rise of the signal inputted to the data input terminal D with that of a signal (g) inputted to a clock input terminal to switch a change-over switch 3. Since the switching timing of the video signal is switched in a vertical blanking period existing before a vertical synchronizing signal by using a head switch pulse synchronizing with the video signal, no noise or skew is generated in a screen and high picture quality can be obtained.
