Title: Liquid crystal panel driving device
Inventor: OKAZAKI NETSUO
IPC: G09G3/36
Filed: 1985-12-29
Abstract: PURPOSE:To display pictures vividly on a liquid crystal panel by controlling the generation period of a polarity inverting signal in accordance with the number of times of turn-on/off inversion in a unit frame. CONSTITUTION:When the number of inversions of turn-on/off in one frame of a data signal outputted from a driving control part 3 is detected in an inversion number detecting circuit 4, an oscillator 5 oscillates and outputs a signal having the frequency corresponding to the number of inversions of turn-on/off in one frame detected by the inversion number detecting circuit 4. This signal is used as a polarity inverted scanning signal and a display signal and is impressed to scanning electrodes and display electrodes of a liquid crystal panel 1 through signal lines 11, 11...11. Since the number of polarity inversions of the scanning signal is varied in accordance with the number of inversions of turn-on/off in one frame, the effectively compensated part is increased as the whole of display picture elements to reduce the disturbance of a display pattern due to the reduction of an effective voltage.

Title: Full-easy-open can lid of non-bent type
Inventor: KONO TAKESHI
IPC: B65D17/40
Filed: 1987-11-25
Abstract: PURPOSE:To increase rigidity of an opening piece to reduce force required for opening a can after initial opening and prevent contents of the can from bering damaged by a method wherein two beads whose start and finish ends are positionally specified are provided. CONSTITUTION:A line l which connects a first end 5a of a start bead 5 and an edge 9 of a fixing portion 4 is tilted with an angle theta with respect to an axis X-Y. When the angle theta exceeds 85 degrees, an opening lid can be easily bent above the start bead 5, and the opening lid cannot be opened deeply in the breaking direction at the initial opening. This prevents moment from being applied at the time of breaking and a breaking force from being reduced after the initial opening. On the other hand, when the angle theta is less than 45 degrees, not only the force applied during the first opening is increased but also a force for starting an opening at a start point 21 for starting an initial opening is increased. The angle theta is thus limited within a range from 45 to 80 degrees. In order to prevent indication depth (h) which may damage contents 10 of the can from increasing, an end edge 6 of a finish bead 6 is positioned longer than the end edge 5b of the start bead 5.
