Title: Electrochromic display device
Inventor: AOYAMA TAKASHI
IPC: G02F1/155
Filed: 1978-07-03
Abstract: PURPOSE: To reduce the thickness of counter electrode material and achieve the reduction in the thickness of the cell by using the sintered body of the paste of the organic compound of metals or the paste containing carbon for the counter electrode.  
     CONSTITUTION: The film obtained by screen-printing the paste composed of organic metal compounds or conductive inert metals such as platinum, Pd or silver or carbonaceous compounds then firing the same at high temperature is used as an electrode 3 for the counter elctrode around the display electrodes 2 on a substrate 1. This enables the reduction in the thickness of the device to be achieved, as a result of which the breakage owing to expansion of electrochromic material may be prevented. Further fine undulations are formed on the counter electrode surfaces because the counter electrode is a sintered body and this results in the increased counter electrode surface area and improved response speed of display.

Filed: 1986-04-09
Abstract: PURPOSE:To prevent the leakage of sodium in a luminous tube to the outside of the tube during operation by through sealing an electric conductor provided with zirconium oxide film on the outside surface in the aperture of the end of an alumina tube with ceramic cement containing calcium oxide. CONSTITUTION:An alumina tube 1 and an end disk 2 and an electric conductor 6 are sealed together with rings of ceramic cement 8 by heating up to a high temperature and melting the said cement.

Abstract: PROBLEM TO BE SOLVED: To improve formability and brazability by specifying a composition of elements. SOLUTION: The Al alloy sheet has a composition consisting of, by weight, 0.4-1.6% Si, 0.4-1.0% Cu, 0.05-0.3% Ti, and the balance Al with <=0.2% Mg as impurity. In the case where a part of this sheet is alloyed with metal and melted and forms a brazing filler metal, characteristics, such as increased amount of brazing filler metal at brazing, excellent fluidity of brazing filler metal, and improved strength and corrosion resistance after brazing, can be obtained. Further, in the case of a sheet with the composition, where the average size of recrystallized grains is regulated to <=70μm and a strain of 1-5% is introduced, formability is improved and, further, the average size of recrystallized grains becomes >=100μm in the course of brazing.  As a result, at the time of brazing, the amount of brazing filler metal is increased and the fluidity of brazing filler metal is improved and a sufficient fillet is formed.
