Abstract:
A photosensitive resin laminate for a sign board is provided, which laminate has a support and a photosensitive resin layer having a thickness of not less than 500 μm formed at least on the support via an adhesive layer, wherein the photosensitive resin layer has an absorbance at 400 nm of not more than 0.4 and the support is a modified polyethylene terephthalate layer on which a UV quality change preventive layer is formed. A sign board obtained using a photosensitive resin laminate of the present invention has a transparent and colorless support having superior design and superior light resistance with a smaller coloring level due to UV. In other words, the photosensitive resin laminate of the present invention can provide a suitable sign board and greatly contributes to the industry.
Abstract:
A electron gun has a plurality of arranged tubular electrodes for passing electron beams inside the tubular electrodes, and the tubular electrodes are fixed to support rods respectively by support members. At least one of the tubular electrodes is separated into two parts, and the separated two tubular electrode parts are connected electrically with each other by a coil member provided therebetween. The coil member is composed of a wire with its tip ends being located within the spaces formed by the support members. A desired electron beam modulation effect can be provided without interrupting transmission of a modulation magnetic field from the exterior, and also electric field emission of electrons from the tip ends of the coil member is suppressed.

Abstract:
A photosensitive resin laminate comprising at least a support, an adhesive layer and a photosensitive resin layer, wherein the photosensitive resin laminate shows a total light transmission of not less than 60%, or satisfies the following formula (1): {(A−B)/A}×100≦15 (1) wherein A is a total light transmission (%) of the support and B is a total light transmission (%) of the photosensitive resin laminate.
Abstract:
A multilayered photopolymer element made up of at least a support, a photosensitive layer and a cover film. The photosensitive layer is composed of at least two layers and the uppermost layer in the photosensitive layer contains a sensitivity controlling agent bonded with a polymer. The shape of the shoulder at a relief top is made sharp-edged whereby a printing plate having excellent print quality without being thickened by impression is prepared.
Abstract:
A finisher is provided with a stapling unit which has a staple head and a staple anvil, the staple head and the staple anvil being separated and independently movable to a stapling point. When the staple head which contains staples is detected empty, the staple head goes to a staple cartridge exchange position. When a jam of staples is detected, the staple anvil goes to a retreating position. Also, a light emitting element is provided at the staple head and a light receiving element is provided at the staple anvil. First, the staple head is moved to/stopped at a specified stapling point, and then, the staple anvil is moved. The staple anvil is stopped when the light receiving element receives a light from the light emitting element.
Abstract:
A photosensitive resin composition which is excellent in flexibility and impact resilience, which is less affected by humidity is provided. This composition comprises a soluble synthetic polymer, a photo-polymerizable unsaturated compound, and a photo-polymerization initiator, wherein the soluble synthetic polymer comprises an addition polymer obtained by the reaction between a diamine compound having amino groups selected from primary and secondary amino groups and having no amide bonds in its molecule and a diisocyanate compound; and the addition polymer contains a polyoxyalkylene glycol component in an amount of 20 to 80% by weight.
