20080203053 | Method for manufacturing magnetic recording medium, stamper, transferring apparatus, and method for forming resin mask - A reliable magnetic recording medium manufacturing method is provided in which a resin material used for processing a recording layer into a concavo-convex pattern can be removed reliably. In the magnetic recording medium manufacturing method, an energy ray curable resin material is spread over a continuous recording layer. Then, a stamper having a predetermined concavo-convex pattern is brought into contact with the resin material to transfer the concavo-convex pattern to the resin material, and the resin material is irradiated with energy rays such that the irradiation energy on a portion excluding the edge portion of the resin material is greater than that on the edge portions. The curing reaction proceeds to a greater extent in the portion excluding the edge portions than in the edge portions. Then, the resin material is etched and removed such that more resin material is removed from the edge portions than from the other portion. | 08-28-2008 |
20080230960 | Method for manufacturing information recording medium, method for forming resin mask, transferring apparatus, and light-transmitting stamper - An information recording medium manufacturing method is provided in which a resin material can be reliably cured even when a light-transmitting stamper is used repeatedly. A resin mask forming method and a transferring apparatus and a light-transmitting stamper used in these methods are also provided. In the above methods, a visible light curable resin material is spread over a workpiece. Then, a light-transmitting stamper including a transferring portion having a predetermined concavo-convex pattern formed therein is brought into contact with the resin material to transfer the concavo-convex pattern to the resin material, and light including visible light is projected onto the resin material through the light-transmitting stamper to cure the resin material. | 09-25-2008 |
20080237938 | Method for manufacturing information recording medium, method of transferring concavo-convex pattern, and transfer apparatus - A method for manufacturing an information recording medium, a method of transferring a concavo-convex pattern, and a transfer apparatus are provided which are capable of curing a resin material with reliability even when using a light-transmitting stamper repeatedly. A stamper made of a light-transmitting resin, having a predetermined concavo-convex pattern formed on its transfer area, is inspected for an optical characteristic. The stamper is brought into contact with an energy-ray curable resin material applied to an object to be processed, thereby transferring the concavo-convex pattern to the resin material, and the resin material is irradiated with an energy ray through the stamper so that the resin material cures. The stamper is used a plurality of times to repeat these steps a plurality of times, thereby manufacturing a plurality of information recording media. | 10-02-2008 |
20090100677 | IMPRINTING METHOD, INFORMATION RECORDING MEDIUM MANUFACTURING METHOD, AND IMPRINTING SYSTEM - An imprinting method which is capable of forming desired concave/convex patterns on opposite surfaces of a substrate with high accuracy while making it possible to easily peel both stampers off the substrate after completion of a pressing process. As one stamper formed with one concave/convex pattern and the other stamper formed with the other concave/convex pattern for transferring the respective patterns to opposite surfaces of a substrate, there used are one stamper and the other stamper which have similar shapes in plan view and plane areas larger than that of the substrate. The one and the other stampers are pressed against opposite surfaces of the substrate, respectively, such that at least part of an outer periphery of one of the two stampers does not overlap the other in a direction of a thickness of the substrate. | 04-23-2009 |
20090166930 | PEELING APPARATUS, PEELING METHOD, AND METHOD OF MANUFACTURING INFORMATION RECORDING MEDIUM - A peeling apparatus including a first holding section that holds a first object which is in the form of a flat plate, and a second holding section that holds a second object which is in the form of a flat plate and is affixed to the first object to be integral, the peeling apparatus being configured to be capable of peeling one of the first object and the second object off the other in a state in which the first holding section holds the first object and the second holding section holds the second object. The first holding section holds the first object by being brought into contact with a surface of the first object along a direction of a thickness thereof via at least two points. | 07-02-2009 |
20090250521 | NON-CONTACT TYPE IC CARD - There is provided a non-contact type IC card that prevents electrostatic discharge failure of an IC chip embedded in an IC card. | 10-08-2009 |
20100143586 | Spin coating apparatus, spin coating method, and method for manufacturing information recording medium - The spin coating apparatus includes: a collet including a tubular portion disposed coaxially with a predetermined rotation axis, the tubular portion having a slit that extends from a top portion of the tubular portion in a direction of the rotation axis to a midway part in the direction of the rotation axis; and a diameter-expanding member for urging the tubular portion of the collet radially outwardly to expand the outer diameter of the tubular portion. With the spin coating apparatus, a plate-like workpiece having a center hole is held at the center hole by the tubular portion of the collet with both sides of the workpiece exposed, and a flowable material can be applied to both the sides of the workpiece. | 06-10-2010 |
20100143965 | METHOD FOR PRODUCTION OF ANTIMUTAGENIC SUBSTANCE USING LACTIC ACID BACTERIUM - Disclosed is a method for producing an antimutagenic substance by using a lactic acid bacterium, which can produce the antimutagenic substance in a large quantity in an extremely simple manner and is economically advantageous; particularly a method for producing an antimutagenic substance effective for a carcinogenic substance, particularly a heterocyclic amine (HCA) which is a carcinogenic substance derived from a food, by using a lactic acid bacterium. Specifically disclosed is a method for producing an antimutagenic substance by using a lactic acid bacterium, which is characterized by suspending the lactic acid bacterium in a poorly nutrient or nutrient-free medium and leaving the lactic acid bacterium in the medium. Preferably, the poorly nutrient or nutrient-free medium is selected from the group consisting of physiological saline, a phosphate-buffered saline without a calcium or magnesium salt (PBS (−)), a citrate buffer, a distilled water, an ion-exchanged water, a natural water, a well water, a tap water, a mineral-added water, a vitamin-added water, an ion supply beverage for an athlete and the like. More preferably, the lactic acid bacterium is | 06-10-2010 |
