IPC: H05G1/56
Filed: 1984-01-18
Abstract: PURPOSE:To extremely lower a thermal loss during irradiation of X-ray and extend the life span of switching element by selectively driving switching elements having different capacities through the change-over. CONSTITUTION:An alternative voltage supplied from a power supply 1 is rectified by a rectifying means 2 and is then smoothed by the smoothing means 3 and 4. Here, when a switching element changeover means 24 is switched to the side of contact b, this apparatus irradiates the X-ray, timing signals outputted in the specified period from a control means 19 are alternately inputted to the thyristors 20 and 22 of small capacity and thereby the thyristors 20 and 22 are alternately switched. Since a switching speed of small capacity thyristors is high, thermal loss is remarkably less even when the high speed switching is carried out as in the case of this apparatus. Therefore, switching is carried out with the small capacity thyristors 20, 22 having a high switching speed during irradiation of X-ray wherein the switching for a long period is required or with the large capacity thyristors 12, 14 during irradiation of X-ray wherein a heavy current must be allowed.

Abstract: PROBLEM TO BE SOLVED: To confirm a document by reducing a scroll operation by removing a space or a tab up to the first character or character string of a line for each line, thereby displaying the character or the character string from the head of a sentence. SOLUTION: When the instruction of simplified display is received from a display switch instructing means 105, a retrieving means 106 reads document data out of a document data storage means 103 for each line and retrieves the display part position of previously processed document data corresponding to format information consisting of centering and right-justifying. Then, a document processor 102 is further provided with a changing means 110 for changing the display start position of processed document data into left-justifying on a display screen, and a display control means 108 displays the document data at the display start position changed by the changing means 110 on a display means 104. Thus, by switching into simplified display, data are displayed by left-justifying format to left while ignoring the format setting of centering or right-justifying for each line. Therefore, much more documents are displayed on the limited display screen.

Abstract: PURPOSE: To realize a high quality color.halftoning by using the error propagation method of a masaic.color display device and specifying the errors propagated to a first element on the diagonal line. CONSTITUTION: A picture element i(m, n) has a luminance value I(m, n) which is one of (q) possible values. A display element d(m, n) has a luminance value Dm, n which is one of (r) possible values, where q>r and related values T1 to T(r-1) exist between respective (r) display luminance values A1 to Ar. Note that E(m, n)=I(m, n-1)+B(m, n-1)-D(m, n-1). E(m, 1) is only the function of time and m and an error value E(M, n) is defined for each m and n. If the mosaic has a same color diagonal, the error E is propagated on the diagoanl line direction. Thus, an error propagation color.halftoning is obtained with a good performance.

Title: Automatically winding type cover
Inventor: KISHIMOTO DAIZABURO
IPC: B65H75/38
Filed: 1990-01-17
Abstract: PURPOSE:To ensure the smooth winding of a night cover when drawn out, and the slow winding thereof when stored, and prevent the damage of a fluorescent lamp, a thermostat or the like by supporting one end of a cover winding rod on a fixed member via a one-way type rotary damper for suppressing a winding speed via the application of braking effect on the winding force of a winding spring. CONSTITUTION:One end of a cover winding rod 22 is supported with a one-way type rotary damper 32. The rotary damper 32 does not cause viscous resistance to act in a night cover drawing direction. Consequently, a rotary shaft 33 smoothly rotates and the night cover 3 can be lightly drawn out. When the night cover is wound with the winding elastic force of a spring 27, the rotary shaft 33 rotates in a direction opposite to the aforesaid drawing direction. In this case, for the rotation of the shaft 33 in a rewinding direction, the rotary damper 32 causes the viscous resistance of material contained therein to act on the rotary shaft 33, thereby preventing the sudden rewinding rotation thereof. According to the aforesaid construction, the night cover 3 is gradually wound, and a trouble such as fluorescent lamp failure due to an impact can be prevented.
