Title: Production of metal oxide film
Inventor: SASAKI YASUHIRO
IPC: C23C8/12
Filed: 1994-05-31
Abstract: PURPOSE:To form a film which is stable and has good quality by introducing halogenated gas of metal or oxygen-contg. gas into a reaction chamber to deposit prescribed metallic oxide on metal. CONSTITUTION:Slurry contg. metal power and/or metallic oxide powder is applied to the surface of a cylindrical substrate 6 and dried to form a metal and/or metallic oxide film. Thereafter, the cylindrical substrate 6 on which the metallic oxide film is formed is placed in a vapor phase reaction chamber 5 with its blind part upward. Halogen-contg. gas, carrier gas or the like is introduced into the reaction chamber 5 from a gas control device 7 and a gas introducing pass 8. An evaporation source 10 is installed in the reaction chamber 5, and an evaporation material on the evaporation source 10 is heated by a heater 9. The halogenated gas and the evaporation material come into contact with each other to form halogenide of metal. When oxygen-contg. gas is introduced from an oxygen feeding route 12, prescribed metallic oxide is deposited inside or on the surface of the metal and/or metallic oxide film. In this way, cracks and film peeling are eliminated.

Title: Liquid crystal display element
Inventor: NAKAGOME TAMIHITO
IPC: G02F1/13
Filed: 1982-07-09
Abstract: PURPOSE:To provide a liquid crystal display element having good time-division and response properties, prepared by sealing a twisted Np liquid crystal composition containing specified two types of compds. between a pair of light transmitting electrode plates. CONSTITUTION:The display element is prepared by sealing a twisted Np liquid crystal composition between a pair of light transmitting electrode plates. The Np liquid crystal composition contains at least one compd. of formula I (where R is CnH2n+1 or OC2n+1; n is 2-5), at least one compd. of formula II (where R is CnH2n+1; n is 2-7) and a compd. of formula III (where R is CnH2n+1; n is 1-5) or formula IV (where R is CnH2n+1; n is 2-6). The compd. of formula I improves time-division property and the compd. of formula II acts as a viscosity reducer to produce a display element having a low viscosity exhibiting improved response. The addition of III or IV increases TN-1 point without increase in viscosity. Thus a liquid crystal display element having good response property and a wide liquid crystal temperature range is obtained.
