Abstract: PURPOSE:To provide a catalyst for decomposing N2O which is capable of efficiently decomposing N2O contained in exhaust gas and excellent in durability by making ruthenium and iridium in a specified range of Ru/Ir (mol ratio) carried on a hydrophobic carrier such as silica gel, activated alumina or silica- alumina. CONSTITUTION:A hydrophobic carrier is obtained by preparing fine powder of silica gel, alumina or silica-alumina, etc. The hydrophobia carrier is immersed in the ethanol solution of ruthenium and iridium which are regulated to mol ratio of (0.30-5.00) for a specified time and coimpregnated with these noble metals and dried. Thereafter the hydrophobic carrier is burned at 300-500 deg.C for 3-5 hours and furthermore reducing treatment is performed at 400-500 deg.C for 3-5 hours in H2 flow. The properly carried amount of noble metals is regulated to 0.3-2wt.% expressed in terms of metal. A ctalyst for decomposing nitrous oxide is obtained in such a way and catalytically decomposes nitrous oxide contained in exhaust gas with good efficiency. Simultaneously change with the lapse of time is difficult to be caused and the catalyst has excellent peculiar effect.

Title: Electrode structure of liquid crystal display element
Inventor: TANAKA OSAMU
IPC: G02F1/1343
Filed: 1991-12-27
Abstract: PURPOSE:To provide the electrode structure of the liquid crystal display element in which the breakdown destruction of electrodes by static electricity is prevented. CONSTITUTION:Patterns 17 of the transparent electrodes for display are formed of ITO films having 20 to 70OMEGA/squ. resistance value on a glass substrate 11 as before. An electrode pattern 20 is formed of an ITO film having 1MOMEGA/squ. resistance value so as to cover these electrode patterns 17. A current value is extremely small in ordinary use and, therefore, voltages are substantially not applied to the electrode 20 of the ITO film having 1MOMEGA/squ. resistance value (threshold value is not attained) and the display grade is not affected as there is no transmission of light. On the other hand, the current is passed in the pattern of the electrode 20 and the generation of a spark is obviated if the static electricity of several tens thousands to several hundred thousands V is locally impressed and, therefore, the electrostatic breakdown of the electrode pattern 17 is prevented.
