    摘要: An ultrasound treatment system in accordance with the present invention comprises an ultrasonic transducer, a handpiece, a probe, a sheath, a clamping member, an operation unit, an operating member, a suction base, and a perfusion base. The ultrasonic transducer generates ultrasonic vibrations. The handpiece has the ultrasonic transducer incorporated therein and serves as an operation unit. The probe is connected to the ultrasonic transducer, and serves as a vibration transmitting member for transmitting ultrasonic vibrations to a distal member realizing a stationary portion that is a treatment portion for treating a living tissue. The sheath serves as a protecting member for shielding the probe. The clamping member is opposed to the distal member at the distal end of the sheath, and realizes a movable portion that is another treatment portion for clamping a living tissue in cooperation with the distal member. The operation unit is manipulated for clamping a living tissue with the clamping member and distal member or freeing the living tissue therefrom. The operating member drives the clamping member responsively to a manipulation performed on the operation unit. The suction base is formed on the back end of the handpiece, and communicating with a through hole bored substantially along the center axes of the probe and ultrasonic transducer. The perfusion base is formed on the outer circumference of the handpiece and communicating with the lamen of the sheath.

    摘要: In a data extraction circuit used for reproducing character data such as a closed caption and a text, a horizontal sync digital PLL circuit generates an fh sync system clock signal, which is synchronized with a horizontal sync signal fh, in response to a digital video signal from an ADC. Based on the fh sync system clock signal, a clock generation circuit generates a data extracting clock signal which is synchronized with the horizontal sync signal fh. The data extracting clock signal can thus be caused to follow horizontal jitters. Consequently, character data can be reproduced with stability, irrespective of variations in frequency.
