摘要:
One package for photographic film (PF) has five cassettes (3), which respectively contain the photographic film (PF). Five cylindrical watertight cases (2) respectively contain the cassettes (3). Heat shrinkable film (7, 25, 30, 57) is disposed around the five watertight cases (2), and shrunken by heat for collectively covering the five cassettes (3). The shrinkable film (7, 25, 30, 57) has shrinkability from 40 to 63% when heated at 140.degree. C. for 10 seconds, and has thickness from 35 to 50 .mu.m.

摘要:
The technical problem to be solved is to change the thickness of the colored resin layer of the preform gradually in the upward or downward direction, by utilizing a tendency of gradual decrease in the thickness of the colored resin layer caused by the flow of the main resin inside the preform mold when the main resin and the colored resin are injected into the mold. This involves adjusting the injection pattern including the time of starting and ending the supply of the main resin and the colored resin, and pressure or velocity profiles, reducing the thickness of the colored resin layer gradually upstream or downstream, injection-molding the preform in which a color-gradated portion associated with the thickness of the colored resin layer has been formed, and biaxially drawing and blow molding this preform into a bottle having a color-gradated portion.

A biaxially drawn, blow-molded bottle and its preform comprise at least a layer of a gas barrier material laminated inside the PET resin layers, a functional portion having a screw thread raised spirally in the upper portion of neck and also having a stop ring disposed under the screw thread, and a neck ring disposed at the lower end of the neck. In these preform and bottle, the leading edge of the gas barrier layer is positioned at a half height of the neck ring where the most advanced front of the leading edge neither reaches a half height of the stop ring nor extends to the functional portion. It is intended here that the neck would not be affected by the shrinking deformation caused by the existence of the gas barrier layer in the functional portion of the neck, which is treated for thermal crystallization.

An image forming apparatus which performs toner discharge control for held toners of respective colors, comprises: an image carrier; a transfer member on which toner images of the respective colors formed on the image carrier are transferred and superposed; a calculation unit configured to calculate toner amounts used to form the toner images of the respective colors; and a control unit configured to superpose toners of at least two colors onto the transfer member when the toner amounts calculated by the calculation unit are smaller than a predetermined consumption amount, wherein the control unit decides a combination of colors of the toners to be superposed in accordance with differences between the toner amounts and the predetermined consumption amount.

摘要:
A pair of teremps of a knitted structure are bonded to a blank of a shell plate of a film cartridge. A pair of teremps in continuous lengths is conveyed in the longitudinal direction thereof with the piled side of each of the teremps kept in contact with a locator member. The teremps in continuous lengths are bonded to opposite side edges of the blank and then cut to conform to the blank. Before they are brought into contact with the locator members, the teremps in continuous lengths are subjected to a process in which the pile is substantially uniformly oriented rearward at an angle with respect to the direction in which the teremps are conveyed.
摘要:
The technical problem to be solved by the invention is to change the thickness of the colored resin layer of the preform gradually in the upward or downward direction, by utilizing a tendency of gradual decrease in the thickness of the colored resin layer caused by the flow of the main resin inside the preform mold when the main resin and the colored resin are injected into the mold. The objects of this invention is to provide a biaxially drawn, blow molded bottle having new decorativeness created in which sophisticated color gradations associated with color density are created in the body of this bottle. The means of accomplishing this object involves adjusting the injection pattern including the time of starting and ending the supply of the main resin and the colored resin, and pressure or velocity profiles, reducing the thickness of the colored resin layer in the multi-layered molten resin fluid gradually at an upstream or downstream point of the flow, injection-molding the preform in which a color-gradated portion associated with the thickness of the colored resin layer has been formed, and biaxially drawing and blow molding this preform into a bottle having a color-gradated portion associated with the color density or color shade created on the body of the bottle.
摘要:
A container made of synthetic resin which does not cause whitening or clouding in an unstretched portion even after long-period storage and which has excellent barrier properties. A PET bottle comprising a substrate layer made of PET and a barrier layer having a gas permeability lower than that of the substrate layer, wherein the barrier layer is made of a barrier material prepared by incorporating a polyamide containing m-xylene groups with an amorphous polyamide comprising both m-xylene isophthalamide structures and hexamethylene isophthalamide structures. A copolyamide composed of both a copolymer of m-xylenediamine and isophthalic acid and a copolymer of hexamethylenediamine and isophthalic acid is used as the amorphous polyamide. The content of the amorphous polyamide in the barrier layer is adjusted to 15 to 25 wt %.
摘要:
A preform is formed by compounding a resin made from poly-L-lactic acid with a functional filler and subjecting a mouth portion to a heat treatment. Also, a hollow shaped product is produced by blow-molding the preform.
