Title: Treatment of ito powder for low resistance
Inventor: KOJIMA MORIKAZU
IPC: C01G19/00
Filed: 1991-07-23
Abstract: PURPOSE:To stably produce indium oxide-tin oxide(ITO) powder having low electric resistance without agglomerating the ITO powder, by heating the ITO powder in an inert gas containing an alcohol vapor. CONSTITUTION:ITO powder is heated in an inert gas atmosphere containing an alcohol vapor to produce the ITO powder having low electric resistance. The concentration of the alcohol vapor in the inert gas ins suitably 50-500mg/NI. When the concentration is below 50mg/NI, an unreasonably long time is required for deoxidation and the efficiency of the production is lowered. When the concentration is above 500mg/NI. the control of the final point if the reaction is made difficult because of the increasing rate of deoxidation. The heating in the alcohol vapor-containing atmosphere is performed usually at 200450 deg.C. A temperature below 200 deg.C causes difficulty in sufficient deoxidation and in achieving low electric resistance of the resultant ITO, where as that above 450 deg.C unfavorably results in agglomerated and sintered ITO power.

Abstract: PURPOSE:To cope with a heating value variation in a spindle part due to a working condition change by stopping feedback control once immediately after the working condition change, and regulating a feed liquid temperature positively to the setting one corresponding to the working condition being prestored. CONSTITUTION:When a command of spindle speed, namely, a working condition variation command is outputted from a numerical control system 20, a selector device 34 is once selected to the side of a setting oil temperature command device 32 as long as the specified time (for example, for 3min), a setting temperature corresponding to the command speed being prestored in a memory device 36 is given to a controller 24 of an oil temperature regulating feeder 22, whereby oil temperature to a spindle head 16 is positively regulated via a circulating valve 26, and any variation in relative thermal expansion displacement with a bed 10 is prevented from occurring. Next, when the specified time elapses, the selector device 34 is reset to the side of a regulated temperature command device 28, and feedback control takes place so as to cause a temperature difference between oil temperature to be detected by sensors 38 and 40 and the bed 10 to become the specified value. Thus, such oil temperature control that is good in responsiveness is performed even after immediately after the working condition variation, thus machining accuracy is securable.

Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To prevent a display in a reflection display mode and a display in a transmission mode from occurring negative/positiveinversion by arranging a reflecting polarizer under a liquid crystal panel. SOLUTION: Under an STN liquid crystal panel 20, a reflecting polarizer 40 as a 1st polarized light separation means, a diffuser 30 as an optical diffusion means, an illuminator 70 as an illumination means, and a reflecting plate 90 as a light reflection means are arranged in this order. Under external light in a part with voltage impression, the light reflected by the reflection polarizer 40 exits in a form of plane polarized light like a mirror-finished surface, and in a part without voltage impression, the light which has transmitted the reflecting polarizer 40 is diffused by the diffuser 30, and exits in a white form of plane polarized light. Therefore, a mirror-like display to the white ground, namely, a dark display is obtained.  Under lighting of a light source, in the part with voltage impression, the light is absorbed by a polarizing plate 12 to become black, and in the part without voltage impression, the light exits from the polarizing plate 12. Therefore, a black display is obtained for a background color to the exit light color from an illuminator.
