摘要： A photo film cassette has a spool core about which photo film is wound in a form of a roll. A cassette shell contains the spool core in a rotatable manner. Two flanges have a disk shape, and are secured to respective ends of the spool core, for regulating lateral edges of the roll of the photo film. A circumferential lip is disposed on each flange, is extended toward the opposite one of the flanges, wraps one of the lateral edges of an outermost turn of the photo film of the roll, and prevents the photo film from being loosened. A rim portion is disposed on an circular edge of the circumferential lip confronted with the opposite one of the flanges, to project with a bend away from the spool core. A contact face is disposed on the rim portion, and contacts the one of the lateral edges of the photo film when the photo film is unwound from the spool core or wound back about the spool core. The contact face has a contact range of 0.15-0.8 mm in contacting the one of the lateral edges of the photo film. At least one support projection projects from an axially outer face of said flange.

摘要： An injection molding method and an injection mold used therefor are provided, in which a molded product free from burrs, whitening and gate marks can be obtained with a simple structure mold, and it can adequately serve the needs for multicavity molding as well. The injection molding method comprises the steps of: introducing and charging a molten resin material into a resin reservoir and a molding cavity of an injection mold, a depth of the resin reservoir being larger than a thickness of a communicating portion; and moving a cut punch, when a portion of the resin material in the resin reservoir is still molten, to push the molten resin in the resin reservoir back from a gate into a runner so that the cut punch not only closes the communicating portion but also cuts a resin solidified portion in the resin reservoir away from a resin molded product in the molding cavity at the communicating portion.

摘要翻译： 提供了一种注射成型方法和用于其的注射模具，其中可以用简单的结构模具获得没有毛刺，美白和浇口痕迹的模制品，并且还可以充分满足多腔模塑的需要。 注射成型方法包括以下步骤：将熔融树脂材料引入树脂储存器和注射模具的模腔中，树脂储存器的深度大于连通部分的厚度; 并且当树脂储存器中的树脂材料的一部分仍然熔融时，移动切割冲头，将树脂储存器中的熔融树脂从浇口向后移动到流道中，使得切割冲头不仅封闭连通部分，而且还 在树脂储存器中将树脂固化部分从连通部分的模制腔中的树脂模制产品上切下。

摘要： A member used for a photographic sensitive material that is formed from a degradable polymer having a water absorption of 8% or less and a flexural modulus of 1,000 kg/cm2 or more. The member exhibits satisfactory performance as a formed member used for a photographic sensitive material, has no adverse effects on a photographic sensitive material, does not hurt an incinerator upon incineration for scrapping it, and, in the nature, is decomposed or decreased in strength by microbes, light or heat and hence is free from the danger of causing environmental problems.

摘要： The transfer apparatus includes a light source, a transmission type image display device in which a liquid crystal layer is held between two sets of substrates and polarizing plates and a photosensitive recording medium. The light source, the image display device and the photosensitive recording medium are arranged in series along a direction in which light from the light source advances and the image display device and the photosensitive recording medium are arranged in a non-contact state. A display image transmitted from the transmission type image display device is transferred to the photosensitive recording medium. A distance between the image display device and the photosensitive recording medium and a sum total of thicknesses of the substrate and the polarizing plate at least on a side of the photosensitive recording medium in the image display device are set in accordance with a definition of the display image.
