Abstract: An acoustic element integrated circuit includes cells, being arrayed two-dimensionally on a same curved surface, wherein capacitive acoustic-elements having vibration membranes are allocated by unit number in each of the cells. Each of the cells encompasses an intra-cell circuit, which includes an exciting circuit for driving collectively portions by the unit number, the portions having transmitting functions of the acoustic-elements, and a reception circuit for processing collectively received signals transferred from portions by the unit number, the portions having reception functions in the acoustic-elements. Here, the exciting circuits are sorted into a chip in which high-voltage drivers for exciting the vibration membranes are merged and a chip in which circuits operated at voltages lower than the high-voltage drivers are merged, and the cells are operated two-dimensionally, by individually controlling the intra-cell circuits so that cells can be driven independently.

Abstract: In order to easily, rapidly and precisely carry out a setting work after exchange of a pressuring unit, a shank module is provided that is capable of integrally exchanging a shank of a pressing unit. The shank module is configured to removably link a main body and a ram. By adopting the universal pressing unit, adjustment after exchange of the pressing unit becomes considerably easier. Additionally, in carrying out a universal design of a terminal-feeding mechanism, improved workability is implemented by linking the setting of press conditions with the feed conditions of a terminal belt. In order to accomplish this goal, an anvil unit of a press mechanism is configured to be detachable from a main body base. Furthermore, a positioning mechanism is provided on the anvil unit. The positioning mechanism positions the setting position of moving elements of a driving mechanism of a terminal-feeding mechanism corresponding to the terminal belt.
