Abstract: Transfer of fluid substances, and/or substances comprised in fluid substances, is controlled by introducing a separation medium, which prevents transfer of the fluid substances, and/or the substances comprised in the fluid substances, to an intermediate cavity connecting a first cavity and a second cavity; and introducing a connection medium to replace the separation medium and thereby start substance transfer to the second cavity. Substance transfer may be readily controlled without relying on mechanical means. Based on the present invention, two-dimensional electrophoretic analysis can be readily implemented on a chip.

Abstract: The methods for producing microchannel chips of the present invention comprise the steps of shielding substrate surfaces on which groove-like channels have been formed, using a mask that exposes the channels, and then forming polymer membranes on the exposed surfaces of the substrates; and the step of laminating cover materials onto the side of the substrate surfaces on which the channels have been formed.

Abstract: The present invention is to provide a sample separation instrument used in a sample separation apparatus which includes: holding means for holding a first medium supporter which supports a first medium; and driving means for moving fixing means or the holding means in a direction parallel or perpendicular to a plane whose sides extend in the first direction and in the second directions. The sample separation instrument includes an insulator for storing a second medium which allows a sample separated in the first medium in the first direction to be further separated in the second direction different from the first direction, wherein: the insulator includes a first opening and a second opening each of which defines the second direction in which the second medium is electrified, and the second opening has a shape which allows the first medium containing the separated sample to be attached to the second medium along the first direction.

Abstract: A display device includes a cabinet that has a liquid crystal display; a connection section that is rotatably provided relative to the cabinet about a first rotating shaft and parallel to the liquid crystal display; a cover body that is rotatably provided relative to the connection section about a second rotating shaft parallel to the first rotating shaft and that opens and closes the liquid crystal display; and spring pins that are provided in at least one of the first rotating shaft and the second rotating shaft and that generate frictional forces upon rotating of the connection section and/or the cover body.

Abstract: An objective of the present invention is to provide electrophoretic separation methods and devices that enable the various features of a substrate surface that comes in contact with an electrophoresis medium to be controlled. The present invention provides methods for electrophoresing substances, which comprises the steps of: (a) adding a substance to be analyzed to an electrophoresis medium retained in a substrate, whose surface that has come in contact with the electrophoresis medium has been coated with a polymer membrane; and (b) adding electrophoretic pressure to the electrophoresis medium. For example, the use of a plasma-polymerized membrane allows the formation of a membrane with homogeneous quality and thickness on the surface of an arbitrary shape. In addition, desired characteristics can be conferred on the surface through selection of monomeric substances. Protein adsorption onto micro-chips can be effectively prevented as well.

Abstract: An electronic apparatus includes an apparatus body, a lid member, a supporting mechanism, an operation section and a control section. The apparatus body has a playback section.
