    • An ultrasonic diagnosis apparatus comprises a probe having a plurality of transducers for performing transmission/reception of ultrasonic waves; a selection circuit for sequentially selecting the transducers for performing transmission/reception of ultrasonic waves; and an A/D converter for converting a reception waveform signal from the transducer selected by the selection circuit into a digital waveform signal. The apparatus also includes a memory for storing the digital waveform signal converted by the A/D converter in correspondence with the selected transducer; and a read control circuit having a wavefront locus address generator for generating a wavefront locus data corresponding to time-of-flight data between each point in an ultrasonic scanning region and respective transducers to synthesize a wavefront converging on a point in the ultrasonic scanning region (including points which are not located on lines normal to the radiating surfaces of the transducers). The apparatus also includes an output unit for outputting the wavefront locus data to the memory as a read address in order to read waveform samples along the wavefront; and a synthesis circuit for synthesizing the waveform samples read from the memory by a read address from the read control circuit.

    • A nozzle for fast plating with plating solution jetting and sucking functions includes an outer cylindrical member and an inner cylindrical member, a plating solution issuing passage being defined between the outer and inner cylindrical members, and the inner space in the inner cylindrical member constituting a plating solution sucking passage. The inner cylindrical member has a front end flared portion having a forwardly flared surface acting to diffuse the solution. The outer cylindrical member has a front open end defining a gap with respect to the flared surface, the gap constituting a jetting port of the plating solution jetting passage. Plating solution supplied from a supply opening of the plating solution jetting passage is jetted from the jetting port toward a workpiece to be plated, the jetted plating solution is discharged from a rear end discharge opening of the plating solution sucking passage.
