Patent application numberDescriptionPublished
20090141610Optical recording medium - In an optical recording medium for conducting at least one of reading and recording of optical information, the optical recording medium includes: a base board; and an antireflection layer composed of at least one layer, which is provided on a surface of a side of the base board where light enters for conducting at least one of the reading and recording of information. A wavelength of light that makes reflectance of the antireflection layer to light to be smallest is longer than that of the light that enters for conducting at least one of the reading and recording of information.06-04-2009
20100085633OPTICAL ELEMENT AND PRODUCTION METHOD OF THE SAME - Disclosed is an optical element for use in an optical apparatus having a light source which emits a light flux with a wavelength λ (350 nm≦λ≦450 nm), the optical element containing: a molded portion formed by molding a resin; and one or a plurality of anti-reflection layers formed on the molded portion, wherein at least one of the anti-reflection layers is made of Si04-08-2010
20100310437Microchip and Method for Manufacturing the Same - Provided are a microchip formed by joining a resinous film onto a resinous substrate, which enables the prevention of a leak due to peeling of a peripheral portion and prevention of deformation and clogging of a microchannel, and a method for manufacturing the same. The microchip comprises a resinous substrate including a first surface in which a channel groove is formed and a second surface on the side opposite to the first surface, and a resinous film joined to the first surface of the resinous substrate. A joint plane between the resinous substrate and the resinous film is composed of a central area including an area in which the channel groove is formed and a peripheral area corresponding to the outer periphery of the central area, the joint strength between the resinous substrate and the resinous film in the central area is larger than 0.098 N/cm, and the joint strength in at least part of the peripheral area of the joint plane is larger than the joint strength in the central area.12-09-2010
20110014422Microchip and Method of Manufacturing Same - Provided are a microchip enabling accurate analysis by preventing a resin film from being deflected into a flow path groove to eliminate the stagnation of a liquid sample and a method of manufacturing the microchip. This microchip includes a flow path that is formed by joining a resin film onto the groove-formed surface of a resin substrate. The deflection angle of the resin film in the sectional surface of the flow path in the width direction is made to be 0 to less than 30° at respective positions of the flow path.01-20-2011
20110033348Microchip and Method for Manufacturing Microchip - A microchip has a resin substrate, which is provided with a first surface whereupon a channel groove is formed and a second surface on the opposite side to the first surface, and the microchip also has a resin film bonded on the first surface. A projection area is larger than the area of the first surface of the resin substrate when the resin substrate is viewed from a direction orthogonally intersecting with the first surface. Thus, warpage of the microchip can be suppressed at the time of thermally bonding the resin substrate and the resin film by a roller.02-10-2011
20110142716Microchip and Process for Producing Microchip - A microchip 06-16-2011
20110151198Micro-Channel Chip and Manufacturing Method and Micro-Channel Chip - A micro-channel chip is produced while preventing a resinous film from sagging into the channel. The chip hence inhibits a liquid specimen from residing therein. With the chip, quantitativeness and reproducibility are heightened. A process for producing a micro-channel chip is provided which comprises bonding a resinous film 06-23-2011
20120020835Microchip - A microchip having a substrate, a cover member joined to one surface of the substrate, and a flow path formed on at least one of joined surfaces of the substrate and the cover member, wherein the microchip includes: a well which is an first opening for communicating into the flow path with a surface opposite to the joined surface of the substrate and is arranged on the substrate; and a chimney which is a member arranged so as to project from the surface opposite to the joined surface of the substrate and has an second opening which communicating into the well, wherein a liquid rise prevention section is formed in the chimney to prevent the liquid from rising to a top portion of the chimney.01-26-2012
