Title: Production of spacer for optical communication cable
Inventor: SATO TADASHI
IPC: G02B6/44
Filed: 1988-08-29
Abstract: PURPOSE:To obviate groove inclination in a spacer section by coating a tension member with a rein and simultaneously extruding the spacer while forming plural line of optical core housing grooves to the resin surface and passing the spacer through as rotary sizing device, then cooling and taking off the spacer. CONSTITUTION:The resin is extruded from a nozzle 6 which has plural projections on the inner periphery and rotates in alternately reversed directions, by which the resin is applied on the tension member 2 and plural lines of the optical core housing grooves 18 are formed on the resin surface to serve as the spacer. The optical core housing grooves 18 are formed in the form in which left-hand lays and right-hand lays are alternately continuous. The groove inclination viewed in the spacer section is generated when the twisting angle thereof is maintained at 360 deg. and the reversal pitch is maintained at 250mm. However, this spacer is cooled and taken off after the spacer is passed through the rotary sizing device 9 and is subjected to groove inclination correction (sizing). The good spacer section having no groove inclination is thus obtd.

Filed: 1982-12-03
Abstract: PURPOSE:To contrive reduction in interlayer distance of light-receiving elements by a method wherein the light-emitting element, which is formed utilizing liquid phase epitaxial growth, is laminated on the light-receiving surface of the light- receiving element. CONSTITUTION:The LED substrate 20, which will be used for a photocoupler, is formed by successively growing an N-GaAs 22, a P-GaAs 23 and a P-GaAlAs 24 on an N<+>-GaAs substrate 21 by performing a liquid phase epitaxial growing method. When said substrate 20 is going to be laminated on an Si photo transistor (TR) 27, an Al2O3 film 28 is coated on the bottom face of the P-GaAs substrate 21 and it is superposed on the light-receiving surface of the photo TR through a transparent insulating layer 29. In the photocoupler of this constitution, the light emitted from the GaAs layer 23 of the light-emitting element is reflected without radiation from the P-side, because the refractive index of the layer 24 is smaller than that of the layer 23, and major radiation is made from the N-side, thereby enabling to improve the radiation efficiency of the single- layer light emission.

Title: Casting mold for casting titanium
Inventor: OBARA ISAO
IPC: B22D21/02
Filed: 1983-11-11
Abstract: PURPOSE:To obtain a Ti casting having no deterioration in properties, particularly the deterioration in a surface property such as rough casting surface or the like by using Mg oxide or Zr oxide in constituting a casting mold for casting the melt of a Ti base metal. CONSTITUTION:A casting mold is constituted of Mg oxide or Zr oxide having approximately >=97.0% purity. About 3-30 parts an org. or inorg. binder such as polymethyl cellulose, Mg chloride or the like is mixed with, for example, about 50 mesh pulverous Mg oxide. If such mixture is calcined at about 1,200-1,400 deg.C, the binder is consumed or is made into an Mg oxide, by which the casting mold consisting essentially of only the Mg oxide is obtd. If the melt of pure Ti or Ti alloy is cast into such casting mold, the reaction between the casting mold material and the molten metal is thoroughly prevented. A Ti casting is thus obtd. without problems such as embrittlement of the surface owing to the blowholes formed on the casting surface and the Ti oxide formed therein and machining of the brittle surface by post working.
