摘要:
A container production method by liquid blow molding. The method includes a head space forming step of forming a head space in the upper portion of a container, in which, with the container disposed in a cavity, a bottom panel portion molded into an upward convex shape on a bottom of the container is inverted by pushing it down with a pushing rod and is plastically deformed into a downward convex shape.

To solve a problem associated with formation of a transparent window portion in a biaxially stretch blow molded container by a nozzle structure of an injection molding apparatus, provided is a biaxially stretch blow molded container formed with a clearly transparent window portion in longitudinal strip shape by effectively preventing mixture of colored resin to window portion. Injection molding apparatus includes in nozzle portion a longitudinal groove flow path, wherein a transparent B resin flows. By, for example, reducing and increasing, respectively, the width and depth of the longitudinal groove flow path on the downstream side, and engraving slits in an inner mandrel and even in a front end portion of a stopper pin, flowability of the B resin in a horizontal direction is enhanced.

An injection molded test-tube-shaped preform, which is subjected to biaxial stretch blow molding, includes a circumferential wall including a longitudinal strip-shaped portion that is made of a transparent or a semi-transparent B resin and that is formed in a longitudinal strip shape penetrating the circumferential wall in a circumferentially predetermined position in the circumferential wall over a predetermined height range. A remaining portion of the circumferential wall excluding the longitudinal strip-shaped portion is made of an A resin that is obtained by coloring a synthetic resin. A portion of the B resin constituting the longitudinal strip-shaped portion flows around an opposite side to the circumferentially predetermined position in which the longitudinal strip-shaped portion is formed, to be laminated in the vicinity of a portion of the circumferential wall made of the A resin that is close to an inner circumferential surface of the circumferential wall.

A technical problem is to fully make up for a restricted upper limit to the preform body wall thickness. An object is to provide a bottle which is narrow-mouthed and yet has a substantially expanded body. The molding process comprises steps of: (1) injection molding a preform in the shape of a test tube taller than the bottle wherein the preform has a cylindrical mouth opening portion disposed in an upper part of the preform, and wherein the mouth opening portion of the preform serves also as a mouth opening portion of the bottle product; (2) thermally shrinking the preform from an initial height so that portions other than the mouth opening portion of the preform would have a height that is smaller than that of the bottle; and (3) setting this thermally shrunk preform in a blow mold and biaxially drawing and blow molding the preform into the bottle.

摘要:
A method for controlling switching in a bidirectional line-switched ring network configured by a plurality of optical fibers and a plurality of nodes, (i) having a first node receive as input an LP-S (or having the first node detect an SF-P) and having a second node adjacent to the first node across a span receive the LP-S (or receive the SF-P), and (ii) having the second node send an SF-R switch request to another node when the second node further detects an SF-R on said span under the above state (i), whereby a method for controlling switching in a bidirectional line-switched ring under conditions where ring switch and LP-S cannot co-exist, but ring switch and SF-P can, is realized, as a whole, in the ring network.
