摘要:
A process for obtaining a composite pharmaceutical preparation which comprises coating or laminating a composition comprising(a) an adhesive substance having a pressure-sensitive adhesive property at room temperature, and(b) a percutaneous absorption type medicine which is solid at 0.degree. C.onto a polymer film capable of allowing the medicine in contact therewith to migrate through the polymer film, the composition being prepared by adding the medicine to the adhesive substance in a higher concentration than the solubility thereof in the adhesive substance.

A hydrophilic therapeutic material comprising a carrier and a drug-containing patching layer formed thereon directly or indirectly, wherein said patching layer comprises a copolymer of 5 to 75% by weight of an acrylic or methacrylic ester having an ether group in the molecule, 85 to 15% by weight of an alkyl acrylate or alkyl methacrylate and 10 to 50% by weight of a polar monomer copolymerizable therewith.
摘要:
A pressure-sensitively adhering multilayer medicinal preparation comprises a pressure-sensitively adhering macromolecular substance layer and a polymer layer adjacent thereto and the drug and adjuvant incorporated in said preparation each can migrate from the layer of its original incorporation into the other, said adjuvant being capable of increasing absorption of the drug. In such preparation, the drug amount per unit volume can be increased.
摘要:
A pharmaceutical preparation comprising a flexible backing and a base material provided thereon is described wherein the base material consists essentially of a polymer having a glass transition temperature of from -70.degree. C. to -10.degree. C. and exhibiting pressure-sensitivity at room temperature, and isosorbide dinitrate or pentaerythritol tetranitrate. This pharmaceutical preparation is applied to the skin, and permits the active ingredient to be absorbed through the skin into the body at a constant rate, and gradually over a long period of time.
摘要:
A wafer laser processing method for forming a groove in a wafer having a protective film on the processing surface of a substrate along a predetermined processing line, comprising a first step for forming a first groove in the protective film along the dividing lines by applying a first pulse laser beam set to an output at which the protective film can be processed but the substrate can not be processed, to the protective film along the processing lines; and a second step for forming a second groove in the substrate along the first grooves by applying a second pulse laser beam set to an output at which the substrate can be processed, along the first grooves.
摘要:
A method for producing many semiconductor chips, each having a semiconductor circuit disposed on the face thereof and a die bonding film stuck to the back thereof, from a semiconductor wafer in which many rectangular regions are defined on its face by streets arranged in a lattice pattern, and the semiconductor circuit is disposed in each of the rectangular regions. The method comprises: a groove formation step of forming grooves of a predetermined depth along the streets on the face of the semiconductor wafer; a protective film sticking step of sticking a protective film to the face of the semiconductor wafer, where the grooves have been formed; a division step of grinding the back of the semiconductor wafer to render the thickness of the semiconductor wafer equal to or smaller than the depth of the groove, thereby dividing the rectangular regions individually; a die bonding film/holding film sticking step of sticking a die bonding film and a holding film, in this order, to the ground back of the semiconductor wafer; a protective film peeling step of peeling the protective film from the face of the semiconductor wafer; a spacing increasing step of stretching the holding film to increase spacing between the individually divided rectangular regions; and a die bonding film cutting step of irradiating the die bonding film with a laser beam from the face side of the semiconductor wafer through the clearance between the rectangular regions to cut the die bonding film along the clearance between the rectangular regions.
摘要:
To have acceptable moisture permeability and enable prevention of deformation due to swelling, the film base material for an adhesive skin patch includes an ether-based urethane resin obtained from at least one member selected from the group consisting of polyoxytetramethylene glycol, butanediol, polyethylene glycol, and polypropylene glycol as a diol component, and methylene diphenyl-diisocyanate as an isocyanate component. The film base material for an adhesive skin patch has a moisture permeability of preferably 800 to 4,000 g/m2·24 hrs. The adhesive skin patch can be produced by forming a pressure-sensitive adhesive layer on one side of the film base material for an adhesive skin patch.
