Title: Driving method of plasma display panel
Inventor: NAKAMURA SHIYUUJI
IPC: G09G3/294
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To stabilize preliminary discharge by providing maintaining pulses relatively becoming reversed polarity to its pulse just before a preliminary discharge pulse. SOLUTION: In a maintaining discharge period C, maintaining pulses Pu and Ps are alternately impressed on a maintaining electrode and a scanning electrode, and a display cell which emits the light in a writing discharge period is made to emit the light so as to be maintainable. After the desired number of discharge times, a pulse Pse is impressed on scanning electrodes Sc1 and Sc2 to Scj as the final pulse, and a single field is completed. Since a preliminary discharge pulse Pp of a succeeding field is impressed on maintaining electrodes Su1 and Su2 to Suj, an interelectrode electric potential difference between the scanning electrodes and the maintaining electrodes is put in the relationship of inverse electric potential when the maintaining pulse Pse is impressed and when the preliminary discharge pulse Pp is impressed.  Therefore, voltage by these electric charge is superimposed on preliminary discharge pulse voltage when the preliminary discharge pulse is impressed by attraction to the respective electrode sides in the cell by impression of the final maintaining pulse Pse, and preliminary discharge is promoted.

IPC: B22D11/00
Filed: 1984-10-18
Abstract: PURPOSE:To diffuse the air introduced into a molten steel in all directions and to obtain a smooth ingot having less ruggedness by dipping a core material which is formed with recesses each having a limited groove size to a grating shape on the surface and is limited in the total area of the projecting parts into the motlen steel and sticking solidified layers thereto.

Title: Sheet pusher device of metal rotary press
Inventor: ISHIBASHI TAKESHI
IPC: B41F7/16
Filed: 1987-09-01
Abstract: PURPOSE:To obtain a highly durable sheet pusher device by detecting the arrival of a sheet pusher at a prearranged position and reducing the movement speed of the sheet pusher by means of a speed reduction means equipped for a drive means. CONSTITUTION:Material to be printed moves while its rear part is pressed by a sheet pusher 6. A sprocket wheel 28 rotates at a standard speed by means of a servo motor 101, and the pusher 6 moves at a constant speed. When the pusher 6 arrives at a prearranged position, a speed reduction position detector 104 is switched ON, and thereby a speed reduction signal is sent to the servo motor 101 from a D/A converter 105 through a servo driver 106. When the sheet pusher 6 passes over the speed reduction position detector 104, the speed reduction position detector 104 is turned OFF, and a signal to the D/A converter 105 is stopped. Thus the whole constitution is simplified because a speed reduction means is not provided for the pusher itself, and consequently, it becomes highly durable.
