IPC: C23C16/30
Filed: 1985-07-23
Abstract: PURPOSE:To attain a change into ultra-low iron loss, and to improve the status of the surface of a steel plate by forming an extremely thin tension film consisting of TiN, TiC or Ti(CN) on the surface of the steel plate through CVD treatment and annealing the steel plate in a H2 atmosphere.

The surface of the steel plat4e is finished to a specular state, center-line mean roughness of 0.4mum or less, through chemical polishing, electrolytic polishing or the like. An extremely thin tension film composed of TiN, TiC or Ti(CN) is shaped onto a plate surface by treating the surface of the steel plate through CVD in a mixed gas of H2 and N2 and/or CH4 in addition to a gas consisting of a Ti compound of TiCl2, TiC3 or TiCl4 or the like, and annealed in a H2 atmosphere within a temperature range of 600-1,000oC. Approximately 10min or 5hr are normally proper as the annealing time in H2 though the annealing time depends upon an annealing temperature. Insulating coating mainly comprising phosphate and colloidal silica is further executed on the steel plate treated in this manner, thus further improving magnetic characteristics.

Abstract: PURPOSE:To obtain a plastic lens with improved unbrittleness and high transparency while improving the polymn. rate by polymerizing neopentyl glycol diacrylate in the presence of a heat curing type polymn. initiator or an ultraviolet curing type polymn. initiator. CONSTITUTION:Neopentyl glycol diacrylate represented by the formula is polymerized in the presence of a heat curing type polymn. initiator and/or an ultraviolet curing type polymn. initiator to obtain a lens. The former initiator includes t-butyl peroxybenzoate and benzoyl peroxyde, and the latter initiator includes benzoin isopropyl ether and 2-ethyl-anthraquinone. Since neopentyl glycol diacrylate has low viscosity and high transferrability, polishing after the polymn. is unnecessary. The time required to initiate the polymn. of neopentyl glycol diacrylate is several hr in case of the heat curing type polymn. initiator, yet when the ultraviolet curing type polymn. initiator is used, the time is only several min.
