    摘要: Non-active columnar members are disposed on both sides of an active columnar member consisting of a piezoelectric ceramic material or a magnetically strainable material. Levers are connected to the active and non-active columnar members via first and second hinges. Convex shells are connected to the levers via third hinges. The displacement of the active columnar member is enlarged via the lever action, thereby enabling a miniaturized ultrasonic wave transmitter having high power capability.

    摘要: An inverse discrete cosine transform apparatus has operation units for operating a combination of plural basic operation matrixes, including rearrangement, addition, subtraction and multiplication. A coefficient C of multiplication is defined as C=cos (n.pi./16) (n:integer), and the basic operation matrixes are represented by equation (6), and operations of matrixes of addition and subtraction are carried out prior to operations of respective matrixes of multiplication.

    摘要: A method of controlling the selections on a reproducible control data structure with two different selection control methods. According to a first control method, single frame plural selectors, to each of which a numerical identifier has been added, are displayed. Branch tables grouping branch data according to selector numbers are provided. A user makes a selection by selecting a selector number. According to a second control method, plural sectors are displayed in a single frame. A user-specified selector and other selectors are provided for visually differentiating between the selectors as a means of prompting user confirmation of the specified selector. A selection confirmed by the user controls the selection by means of the branch data. Branch data usable by both the first control method and the second control method is grouped together by providing the branch data used by the second control method in the branch table used by the first control method.
