Title: Ultrasonic treatment device
Inventor: ETSU YASUYUKI
IPC: A61B18/00
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To improve propagation efficiency by preventing cavitation in a propagation medium on account of a negative pressure wave from a shock wave. SOLUTION: An ultrasonic wave generating source 3 is constituted by gluing together shell-like first and second vibrators 1, 2 formed by piezoelectric ceramics. Then, a pulse controller 4, at the time of driving the first vibrator 1 so as to generate shock wave, drives the second vibrator 2 so that a positive pressure wave with the same amplitude is generated in the timing in which the first negative wave is generated from the shock wave. In addition, the second vibrator 2 is also driven so that the negative and positive. Waves each of the same amplitude are generated in the timing in which the second and onward positive and negative waves are generated from the shock wave. As a result, all extra waves other than the first positive wave from the shock wave can be cancelled, preventing the inconvenience of cavitation in a propagation medium, and enabling the propagation efficiency to be improved.

Title: Connection system between different types of satellite systems
Inventor: MORIKURA MASAHIRO
IPC: H04B7/212
Filed: 1992-01-27
Abstract: PURPOSE:To automatically switch a system to the other satellite communication line when one satellite communication line breaks down without providing a TDMA alarm signal line by transmitting a specified pattern to an earth network. CONSTITUTION:When the satellite communication line is not used or it breaks down, satellite communication TDMA devices 11 and 12 transmit the specified pattern (non-call pattern, for example) to the earth network.
