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.
摘要:
A device for venting fumes given off by an automatic developing system which includes a developing tank, a fixing tank and a cleansing tank. The device includes a cover for airtight placement over the system and a suction case provided on the inner surface of the cover. The suction case has pores directed toward the developing tank and the fixing tank. Fumes in the system are collected, under suction, through the pores.

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

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.
摘要:
A substrate processing apparatus includes a substrate transit table configured to mount thereon a plurality of substrates; a substrate processing chamber configured to process the substrate one by one; a substrate transfer device capable of loading the substrate into the substrate processing chamber from the substrate transit table and unloading the substrate from the substrate processing chamber to the substrate transit table; and N number of (N is an integer equal to or larger than 3) substrate holding devices provided at the substrate transfer device and configured to hold the substrates one by one. Here, a multiplicity of (2 to N−1 number of) substrates are concurrently held by 2 to N−1 number of substrate holding devices among the N number of substrate holding devices and one substrate is loaded into the substrate processing chamber.
摘要:
A divided wall column allows for fractionation of multiple streams while maintaining separate product qualities. Effluents from multiple stages of a reaction system can be processed in a single divided wall column. The divided wall column can produce multiple cuts from each separated area, as well as at least one output from a common area.
摘要:
A substrate transfer apparatus includes forks that are vertically spaced apart from each other with a predetermined distance. When the forks take out the substrates from the first substrate containing part, each of the forks lifts the substrate and supports the same by moving upward from a pre-loading position located below the substrate to be taken out by a predetermined unloading stroke amount. A value of the predetermined distance is set to be equal to the sum of the distance between the substrates contained in the first substrate containing part and the unloading stroke amount.
