Title: Ultrasonic surgical operating device
Inventor: AKIYASU MASAHIRO
IPC: A61B17/32
Filed: 1993-06-08
Abstract: PURPOSE:To provide an ultrasonic surgical operating apparatus which can reduce the amount of heat emission and presents an enhanced crushing ability. CONSTITUTION:An ultrasonic surgical operating apparatus includes a horn 1 for hard tissue, and the horn 1 is comprised of a horn body 1b, cutter tip 1c, and base 1a. Inside of the horn body 1b, a long hole 23 is formed which stretches in the axial direction, and the cutter tin 1c is structured with a large wall thickness. This enables decrease in the weight of the horn body 1b to lead to suppression of the heat emission. Provision of long hole 23 permits increase of the ultrasonic vibration, which leads to enhancement of the crushing ability.

Title: High density composite semiconductor element and power converter using the same
Inventor: ANDO TAKEYOSHI
IPC: H02M7/537
Filed: 1985-06-26
Abstract: PURPOSE:To obtain a high density composite semiconductor element having high reverse blocking voltage, self-extinguishing function and utilizing the features by connecting a diode and a transistor in series. CONSTITUTION:A transistor T has self-extinguishing function, but since it generally has very low reverse blocking voltage characteristics as shown by a solid line curve 1, it cannot be used for a circuit for generating a reverse voltage. The reverse blocking voltage characteristic like a diode S is increased as shown by a broken line curve 2, but does not have a self-extinguishing function. Thus, two eleements are connected in series by connecting two chips formed of elements having different characteristics and functions to obtain a high density composite semiconductor element which has high reverse blocking voltage and a self-extinguishing function and utilizing the features as shown in Fig. (C).

Title: Synchronous coupling system of pal system synchronizing signal generator
Inventor: MATSUBARA YOSHIHIRO
IPC: H04N9/44
Filed: 1978-11-10
Abstract: PURPOSE: To attain synchronous coupling with an external synchronizing signal in an extremely-short time by making a phase comparison without dividing the output of a voltage control oscillator.  
     CONSTITUTION: At the time of synchronism with internal reference signal SS, switches SW 1  and SW 2  are changed over to input-1 sides and internal reference signal SS is compared with the output of voltage control oscillator VCO divided by four by phase comparator PC, so that operations of oscillator VCO will synchronize easily with signal SS. For synchronous coupling with external synchronizing signal SR, switches SW 1  and SW 2  are both changed over to input-2 sides and comparator PC compares signal SR with the undivided output of oscillator VCO. As a result, since an external horizontal synchronizing signal as external synchronizing signal SR are equal in frequency to horizontal synchronizing signal SH based upon oscillator VCO, oscillator VCO synchronizes with signal SR in an extremely-short time.
