  • Publication number: 20110068281
    Abstract: A charged particle beam drawing apparatus forms a map having meshes, forms representative figures, area of each representative figure in each mesh being equal to gross area of figures in each mesh, and calculates a proximity effect correction dose of the charged particle beam in each mesh on the basis of area of each representative figure in each mesh. If it is necessary to change the proximity effect correction dose of the charged particle beam for drawing at least one pattern corresponding to at least one figure, the charged particle beam drawing apparatus changes area of the at least one figure before the representative figures are formed by a representative figure forming portion, and changes the proximity effect correction dose of the charged particle beam for drawing the at least one pattern corresponding to the at least one figure, calculated by a proximity effect correction dose calculating portion.

  • Publication number: 20060036311
    Abstract: A stent comprising a tubular stent matrix of which diameter is extendable and a flexible polymer layer covering the stent matrix. The polymer layer is closely attached to and covers the entire surface of the stent matrix. Since the flexible polymer layer closely covers the entire surface of the stent matrix not only the outer periphery of the stent matrix, the stent has no problem of causing allergic to metal, stimulus of tissues due to metal, and rust development. Since the inner periphery of the stent is a flat and smooth surface covered by the polymer layer without convexes and concaves, the formation of thrombus can be inhibited well. There is no problem of drift between the polymer layer and the stent matrix, thereby maintaining the positional relationship between the stent matrix and the polymer layer before and after the expansion of the stent.

  • Patent number: 6793988
    Abstract: An image transcription method of transcribing an image of the dye on a printing sheet outputted by e.g., a video printer onto a substrate for transcription, such as a cup of pottery or the like. For transcription, a resin is coated on the surface of the substrate for transcription to form a reception layer. This reception layer is dried in an electrical oven to form a support for transcription. A printing sheet carrying an image of a sublimable dye is stacked on the reception layer of the support for transcription and pressured to the reception layer under application of heat and pressure. As the resin for the reception layer, the acrylic resin or the epoxy resin or both are employed. If the resin composed mainly of the acrylic resin is employed, the viscosity of the resin is set to 43 to 52 seconds in terms of the Ford cup viscosity, and the resin discharge pressure from a spray gun is set to 35 kg/m2±0.01 kg.cm2.
