摘要:
A ultrasonic therapeutical apparatus comprises a plurality of ultrasonic vibrators which are disposed in a plurality of concentric circular rows and defining a ultrasonic shock wave generator. The apparatus also includes control means for independently controlling the frequency and the phase with which the ultrasonic vibrators in the respective raws are driven as well as the output levels thereof, thereby allowing only a positive pressure of the resultant ultrasonic wave to be increased while suppressing a negative pressure thereof to eliminate a cavitation effect.

A cavity insert device comprising an insert section capable of being inserted into tracts and cavities, a detection circuit for detecting conditions of components making up the device, such as an observation device formed at the distal end side of the insert section, and a fuzzy inference section for synthetically determining a plurality of information signals outputted from the detection circuit and producing control signals to control the components. The fuzzy inference section employs inference rules which are empirically considered to be desirable, and control is made by the control signals obtained with the fuzzy inference. The device is thus operated in a nearly optimum state.

According to the present invention, a surgical therapeutic instrument includes an insertion unit, a treating unit that is arranged at one end of the insertion unit to be extended in the extending direction at a predetermined angle to the axial direction of the insertion unit, and an operation unit that is arranged at the other end of the insertion unit. The operation unit includes a rotating operation unit to rotate the treating unit, and an opening/closing operation unit to open/close the treating unit. The treating unit includes two pinching members having planar portions, is rotatable in accordance with the rotating operation, and can move at least one of the two pinching members in the direction substantially orthogonal to the plane of the planar portion in accordance with the opening/closing operation.

A general-information storing unit stores general information sets which are managed by a general-information managing unit which is provided in a network. A plurality of sectional-information storing units store respective sectional information sets which are managed by respective ones of a plurality of sectional-information managing units. The plurality of sectional-information managing units are provided in the network. A plurality of personal-information storing units store respective personal information sets which are managed by respective ones of a plurality of personal-information managing units. The plurality of personal-information managing units are provided in the network. An automatic retrieval unit retrieves a predetermined information unit from among the general information sets, sectional information sets, and personal information sets, in response to a relevant retrieval command being input to said information retrieval system. This retrieval is achieved by searching the above information units in either a bottom-up manner or a top-down manner using directory information for managing all the above information units hierarchically.

The present invention relates to ceramics having excellent fusing damage resistivity against melt of metal or other inorganic materials. If a member formed of BN ceramics in the prior art comes into contact with melt of metal, glass or the like, the member would be readily fused and damaged at its contact portion. Hence, if AlN in the range of 1.ltoreq.AlN
摘要:
This invention relates to a connecting structure for electrically connecting an electronic part such as an LSI chip to a substrate, its production method and an electronic device using the former. The present invention is particularly useful for connecting electrically a plurality of chips, for which an absorption function of the difference of thermal expansion in a horizontal direction and capability of displacement in a vertical direction are requisite, to a substrate. Moreover, the connecting structure of the present invention can simplify the fabrication process, has high reliability and can be applied to high performance electronic appliances and apparatuses such as electronic computers.
