Title: Method and apparatus for form-rolling thin-wall metallic part
Inventor: TANAKA TOSHIAKI
IPC: B21H5/02
Filed: 1988-12-28
Abstract: PURPOSE:To form a high-precision and thin-wall part by performing plastic working while fine indentation displacement of a forming roller is controlled in an elastic contact state between the primary and the secondary displacement adjusting body. CONSTITUTION:At the final stage of a form rolling process, a displacement adjusting ring 90 of the secondary displacement adjusting body 9 arranged on the same axis with a roller body 20 abuts on the outer peripheral surface of the displacement adjusting ring 80 of the primary displacement adjusting body set to a blank shaft 60 and a press-contact arbor 61 of a blank holding device 6. The indentation displacement by the roller is adjusted to perform fine dimensional control. In other words, the displacement and indentation speed of the roller in the sizing process can be controlled arbitrarily by controlling the indentation force of the roller. By this method, a high-precision and thin-wall metallic part can be obtained.

Title: Document processing device and method
Inventor: FURUYA YOJI
IPC: G06F17/24
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To enable displaying a document being free from unnatural feeling by scrolling a display screen in the left or right direction with movement amount decided based on lateral width of an adjacent character when an adjacent character is placed at a position exceeding a left frame or a right frame of a display screen. SOLUTION: For example, when a cursor 72 is positioned at the right most end of a display screen and a joystick is operated to display characters of a right side deviated from a screen 71, a CPU detects a character pitch L from a position of the cursor 72 to the characters of the right side (it is decided by a kind of character at which the cursor 72 is positioned), and character width W of a right-adjacent character to be displayed is detected. Next, a value subtracted by character width of a character at which the cursor 72 is positioned from the sum of obtained L and W is made a left-scrolled value. Left-scroll is performed based on quantity obtained by this calculation. Thus, as scroll-display is performed based on size of characters, a document being free from unnatural feeling can be displayed.

Title: Lamp broken-wire detector
Inventor: NODA KIYOSHI
IPC: H05B37/03
Filed: 1989-12-25
Abstract: PURPOSE:To detect causing a broken wire in each of lamps and the arranged position of the wire-broken lamp by having an AC power control means, an open-circuit action judgment means which detects each of changes in AC power outputs, caused each time a corresponding lamp lighting circuit is opened, and the like. CONSTITUTION:A different judgment time is set to each of lamps L1 to Ln in a lighting circuit 5. For each of the lamps, time required until a point of time of detecting a change in an AC power output by an open-circuit action judgment means 9 from a point of time when the output of an AC supply 1 has just been controlled by an AC power control means 8 is counted while each judgment time is made to correspond with each counted time, and then each corresponding counted time of these judgment time is judged so that the lamp corresponding to the resultant judgment time is judged to be the wire- broken one. When broken wires are caused in some of the plurally arranged lamps L1 to Ln, not only the number of the wire-broken lamps but also the arranged position of each of the lamps on whichever of the two has a broken wire can thus be detected.
