    Abstract: A sheet processing apparatus includes a first cylinder, second cylinder, third cylinder, first driving device, second driving device, third driving device, thickness input device, and controller. The first cylinder receives a sheet from an upstream transport cylinder and holds the sheet. The second cylinder is disposed to oppose the first cylinder and prints/coats the sheet held by the first cylinder. The third cylinder is disposed to oppose the first cylinder and supplies ink/varnish to a circumferential surface of the first cylinder. The first driving device adjusts a gap amount between the first cylinder and the upstream transport cylinder. The second driving device adjusts the position of the second cylinder with respect to the first cylinder. The third driving device adjusts the position of the third cylinder with respect to the first cylinder. The thickness input device inputs the thickness of the sheet.

  • Patent number: 7402914
    Abstract: In a semiconductor device, an insulating layer formed on a substrate and a wiring pattern layer is formed on the insulating layer. A lower mark element is defined as a groove formed in the insulating layer, and defines an overlay mark in conjunction with an upper mask element formed in a photoresist pattern coated on the insulating layer for the formation of the wiring pattern layer. The lower mark element features a width falling within a range from approximately 4 to 6 ?m, and a depth of at most 1 ?m.

  • Publication number: 20060128948
    Abstract: The crosslinking agents and condensing agents that have been employed in biological adhesives and in treating medical devices such as cardiac valves are non-natural compounds synthesized artificially. Thus, they are not metabolized in vivo and exhibit toxicity to living bodies. These compounds are thus used only in a restricted amount and for limited purposes in the clinical sites. The present invention provides a biological low-molecular-weight derivative obtained by modifying carboxyl groups of a biological low-molecular-weight compound with N-hydroxysuccinimide, N-hydroxysulfosuccinimide, or a derivative thereof and a crosslinked high-molecular-weight product obtained by crosslinking various high-molecular-weight compounds with this derivative.

  • Patent number: 6589718
    Abstract: A method of making a resist pattern is provided, which decreases or eliminates the fluctuation of deformation of original openings of a resist layer which is induced by the change of their density (i.e., the count of the original openings within a unit area) or by their location in the reflowing process. The method comprises the steps of (a) forming a resist layer on a target layer; (b) patterning the resist layer to form original openings and at least one slit in the resist layer; the slit surrounding the original openings and having a specific width; and (c) reflowing the resist layer patterned in the step (b) under heat to cause deformation in the original openings and the at least one slit, thereby contracting the original openings and eliminating the at least one slit; the original openings thus contracted serving as resultant openings for forming desired contact/via holes in the target layer; the resist layer having the resultant openings constituting a resist pattern.
