IPC: H04N1/00
Filed: 1989-02-20
Abstract: PURPOSE:To color paper white and to enable simulation in an accurate finish state even at the time of printing of paper which is slightly yellowish and not purely white like newspaper by decreasing the gradations of a simulation image. CONSTITUTION:When the background of printed matter is not purely white, a white frame function is used to display a white frame on a color monitor 86 in paper white, and this white frame is colored matching the base of the printed matter. Thus, the highlight-side gradations of a color image signal are varied greatly to the shadow side to adjust white balance, thereby matching the white level of a display image with the color of the background of the printed matter. Consequently, the finish state of the printed matter can be simulated.

Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To improve strength of a ridge structure by arranging projecting strips and divided strip grooves on the surface and a back face in a prescribed state, and forming the suspending parts having a locking groove on both ends. SOLUTION: In ridge tiles, two pairs of parallel projecting strips 9, 9a, 10, 10a and the like are projected on the surface and a back face by arranging locking grooves 13 in the left/right both end lower suspending parts 11. Next, divided ridge tiles 2a are formed by being divided into two parts by arranging divided grooves between the projecting strips 10, 10a of the back face. A circular roof tile 3 is placed on mixed earth 3a of the uppermost part by alternately heaping up the ridge tiles 2a and the mixed earth 3a on a roof tile 6 by arranging rafter clearance 8 on the left/right of the upper surface of the plain roof tile 6 at execution work. In this case, one end of the roof tiles 2a of the lowest stage is placed so as to stride over the upper part of the rafter clearance 8 by binding the mutual opposed roof tiles 2a by a wire.  Next, the roof tiles 2a, 3 are fixedly bound by locking a wire 5 on the locking grooves 13 of the lowest roof tile 2a. In this case, the projecting strips 9, 9a prevent lateral dislocation of the roof tiles 2a by keeping a proper interval between the roof tiles 2a. Therefore, earthquake resistance and wind resistance can be improved while inexpensively manufacturing the ridge tiles in large quantities.
