Abstract: Certain volatile organotin compounds are volatilized in a heated carrier gas stream and brought into contact with a preheated substrate to be coated in an atmosphere containing oxygen. The process is particularly applicable to deposition of tin oxide on glass faceplates of cathode ray tubes.
Abstract: Certain volatile organotin compounds are vaporized in a heated carrier gas stream and brought into contact with a preheated substrate to be coated in an atmosphere containing oxygen. Indium oxide coatings may be doped with tin by vaporizing an organotin compound and an indium chelate of a .beta.-diketone and bringing the vapors in contact with a heated substrate in an oxidizing atmosphere.
Abstract: A layer of unoxidized metal is provided on surfaces of the device in such manner as to possess an oriented microstructure capable of causing sympathetic alignment of the liquid crystal molecules. The metal layer is thereafter heated in the presence of oxygen, preferably in a device envelope sealing process, to oxidize the metal layer. The metal oxide layer is stable, in that it retains the molecular aligning characteristic, and is more transparent than the metal layer.
Abstract: The cell comprises two spaced apart substrates and a plurality of terminals for the cell disposed along an exposed surface of one of the substrates. Electrodes are disposed on each of the substrates, and connector means for connecting one of the terminals on the one substrate and an electrode on the other substrate comprises a fused glass bump bridging the space between the two substrates and electrically connected to the one terminal and the electrode on the other substrate. The glass bump contains metal particles dispersed therethroughout to provide it with electrical conductive characteristics.
Abstract: In preparing an electron beam resist film of a copolymer of an olefin and SO.sub.2, the steps of removing insoluble particles, drying the films under high vacuum and storing them in a moisture-free atmosphere are required to prevent cracking of the films during development.

Abstract: Photochromic lithium niobate crystals containing iron and either manganese or copper are useful for recording phase holograms in the photosensitive state of the crystals, which holograms can be permanently fixed and read out without loss in the quality of the image obtained therefrom over extended periods.
Abstract: Lithium niobate single crystals doped with iron can be treated to reduce trivalent iron to divalent iron without reduction of the lithium niobate host crystal, by surrounding the crystal with a high-melting salt of lithium, such as lithium carbonate, and heating in an oxygen-containing atmosphere until the desired amount of reduction is obtained.
