Abstract: A hand held applicator for applying ultrasound power to treat human tissue, includes a transducer (1) having excitation electrodes. A power amplifier (13) responds to an oscillating signal from a variable frequency oscillator (23) to supply electrical power to the transducer (1) via a connection to the excitation electrodes. The transducer (1) and the power amplifier (13) have a power-conversion-efficiency characteristic that is a function of the frequency of the oscillating signal and the acoustic load on the transducer (1). The frequency of the oscillating signal is controlled by a sampler (5) having a timer for defining alternating sample and hold timing intervals and means for producing a frequency-control signal having a magnitude that varies during each sample interval and that remains essentially constant during each hold interval. The means for producing the frequency-control signal includes a peak-detector operative during each sample interval for setting the magnitude of the frequency-control signal so that throughout the ensuing hold interval the transducer and the power amplifier operate with essentially peak-power-conversion efficiency.

Abstract: An electrode for engraving electric spark machining which is produced by using a mixture of gypsum hemihydrate powder serving as both a principal material and a binder with a conductive metal powder as a filler, transferring, shaping and hardening the mixture into a desired shape to form electrode material and plating the electrode with the conductive metal. Gypsum hemihydrate powder, gypsum dihydrate powder of less than 1 vol % on the basis of the former and the conductive metal powder are kneaded in a vacuum. Water is added to the kneaded matter, which is again kneaded in a vacuum, poured into a mold to which a predetermined shape is transferred, shaped and hardened by hydration to obtain an electrode material. Then the electrode material is dried and plated with the conductive metal so as to reinforce electrical connection with the metal powder. Since the electrode is made of gypsum as the principal material, even an electrode for electric spark machining to which a precise and complicated shape is transferred can be produced easily, economically, and precisely by the use of a simple mold of, e.g. a silicone rubber, and hence it is particularly suitable for producing dental crowns one by one. Furthermore, gypsum hemihydrate as the principal body of the electrode material and the conductive metal film increase the strength of the electrode by virtue of their synergistic effect. The present invention makes possible machining of a hard material such as titanium for which precise electric spark machining at a desired speed has been difficult by the use of a conventional electrode subjected to impregnation treatment of a conductive solution in which graphite or the like is dispersed in place of plating treatment.

Abstract: The present invention relates to a novel process for forming metal matrix composite bodies by using a reactive barrier material. Particularly, an infiltration enhancer or an infiltration enhancer precursor or an infiltrating atmosphere are in communication with a filler material or a preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform up to the reactive barrier material. Such spontaneous infiltration occurs without the requirement for the application of any pressure or vacuum. Accordingly, shaped metal matrix composite bodies can be produced having superior surface finish.
