Title: Driving method for gas discharge display device
Inventor: ASAI HIDEYUKI
IPC: G09G3/298
Filed: 2003-04-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide a driving method for a gas discharge display device capable of performing writing over the entire surface with a low voltage even if there is large spacing between a display electrode and a scanning electrode.  <P>SOLUTION: An initialization voltage is applied between the display electrode 52a and the scanning electrode 52b and a writing electrode 28, by which the full surface writing discharge to make a barrier charge quantity uniform between these electrodes is generated. Consequently, even when the firing potential between the display electrode 52a and the scanning electrode 52b is made higher due to the spacing therebetween as large as about 350 (μm), the full surface writing discharge is generated between the display electrode 52a and the scanning electrode 52b in which the firing potential remains at a value lower than the same and the writing electrode 28, by which the initialization at the lower voltage is made possible.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Inventor: ITO SEISHIRO
IPC: C02F1/58
Filed: 2003-04-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide a treatment technique where aluminum components are easily and efficiently precipitated from an alkali waste liquid containing aluminum at a high concentration, and an alkali solution is reutilized.  <P>SOLUTION: In the method of removing aluminum contained at a high concentration from an alkali waste liquid used for removing aluminum-containing matter stuck to a die for extrusion molding, lithium hydroxide is added to the waste liquid, and thereafter, solid-liquid separation is performed. In the method of treating an aluminum-containing alkali waste liquid, though the discard of an alkali waste liquid containing aluminum at a high concentration has heretofore been entrusted to an agent as it is at a high cost, the waste liquid is subjected to solid-liquid separation, and only precipitates are discarded, and a filtrate is reutilized. Thus, not only an economically great advantage is caused, but also, remarkable contribution can be brought out to an environmental problem.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
