Filed: 1986-12-24
Abstract: PURPOSE:To miniaturize a structure for cupling a transmission lever with a transmission valve so that the operation unit in the caption can be arranged in any bent and curved state, by arranging a part of the wire portion of a pair of coupling wires wound around a wire pulley on the valve side, so that said pair of wires can be seen overlapped when viewed in the core direction of the rotary shaft of the wire pulley on the valve side. CONSTITUTION:When a transmission lever 22 is operated in swinging motion, a wire pulley 20 on the lever side makes turning movement so that a pair of wires 19a, 19b used for coupling may increase this rotational speed by means of a difference between the wire winding diameters of wire pulleys 20, 18 on the lever side, an the valve side respectively so as to transmit said rotation to the rotation operation shaft 17a of a transmission valve 17. Therefore, since the rotation can be transmitted in an increased state of its speed and the wire winding diameter of a wire pulley 18 on the valve side can be decreased as small as possible, a coupling structure can be miniaturized. Furthermore, it is also possible to arrange this unit in any bent and curved space and to miniaturized the transmission valve 17.

Filed: 1999-11-01
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of a memory for storing the results of first-stage one-dimensional orthogonal transformation and to obtain desired result data of two-dimensional orthogonal transformation at high speed. SOLUTION: In the two-dimensional orthogonal transformation method, the first matrix element 23a of intermediated data is first obtained by performing sum of products operation on the first-row vector 21a of input image data and the first-column vector 22 of a transformation factor matrix. Then the second matrix element 23b of the intermediate data is obtained by performing sum of products operation on the second-row vector 21b of the input image data and the first-column vector 22 of the transformation coefficient matrix. Thus each matrix element of the intermediate data is generated in the vertical direction in first-stage one-dimensional orthogonal transformation. Immediately after the matrix element of eighth (eighth in one column) intermediate data is decided, second-stage (in the vertical direction) one-dimensional orthogonal transformation can be started.
