摘要： A cassette-type molding die comprises a die plate unit having fitting bores and a cassette die unit including movable and stationary cassette plates between which a molding cavity is defined, an ejector cassette plate, and ejector pins disposed between the movable cassette plate and the ejector cassette plate. The cassette die unit can be detachably inserted into the fitting bores of the die plate unit. As a result, the cassette die unit can be easily exchanged with another cassette die unit while the movable and stationary die plates of the die plate unit are very close together. This speeds up the process of changing cassette die units, and also allows for the overall cassette-type molding die to be smaller than conventional units.

摘要： A ultrasonic transducer using such a piezoelectric composite that a number of piezoelectric poles made of piezoelectric ceramics are arranged in a plate-like polymer matrix perpendicular to the plate surface. The volume ratio of the piezoelectric poles is set in a range of 0.15-0.75 and a spacing between every adjacent piezoelectric poles is set smaller than the thickness of the polymer plate, thereby resulting in a transducer which has higher sensitivity than the conventional one using a homogeneous piezoelectric ceramic plate.
