Abstract: To provide a chromatography carrier that has excellent antifouling properties and exhibits excellent pressure-resistant performance and shatter-resistant performance. A chromatography carrier comprising: a polymer having a partial structure containing at least two groups represented by —C(?O)—NH—.

Abstract: Provided is an affinity chromatography carrier that suppresses nonspecific adsorption of impurities, suppresses a decrease in dynamic binding capacity due to long-term storage, and has high storage stability. The affinity chromatography carrier includes a solid support including a copolymer including (M-1) more than 20 parts by mass and 99.5 parts by mass or less of a structural unit derived from an epoxy group-containing monovinyl monomer with respect to and (M-2) 0.5 to 80 parts by mass of a structural unit derived from a polyvinyl monomer with respect to all structural units; ring-opened epoxy groups obtained by subjecting the epoxy groups to the ring-opening ; and a ligand coupled to the solid support, and is such that after a certain column vessel is packed with the affinity chromatography carrier and then purged with a 2 M NaCl-containing 20 mM sodium phosphate buffer with a pH of 7.5, allowing the column to stand at 40° C. for 7 days increases pH in the column by at most 2.

Abstract: A laparoscope supporting device which is attached to a body wall face of an examinee and supports a laparoscope to be inserted in a body cavity of the examinee by using an inserting tool as a guide, the device comprises: a grasping portion that grasps the inserting tool; and a support portion that supports the grasping portion in a movable manner in a predetermined direction.

Abstract: A balloon control device for controlling an expansion and contraction of a balloon fixed to one of an insertion unit of endoscope and an insertion adapter by supplying and suctioning of fluid to the balloon, comprising: a channel for conveying the fluid between the balloon control device and the balloon; and a gas/liquid separator for separating gas and liquid from the fluid in the channel.

Abstract: The improved light-sensitive material transporting device includes a belt conveyor for transporting a light-sensitive material as it is placed thereon; and an auxiliary belt conveyor that is driven in the same direction as a transport direction of the belt conveyor and which is spaced above the belt conveyor wherein a distance between the auxiliary belt conveyor and the belt conveyor decrease progressively from upstream to downstream in the transport direction of the light-sensitive material. The light-sensitive material transporting device is capable of transporting the light-sensitive material in a consistent and smooth manner while correcting the "curls" it has. In addition, by adopting the device in the distributing section which distributes individual sheets of the light sensitive material into a plurality of rows, the pathlength of the light-sensitive material can be shortened while, at the same time, the cost of the apparatus is measurably reduced.

Abstract: The improved back printing apparatus for recording a back print on a non-exposed surface of a light-sensitive material to be subjected to wet photographic processing comprises a charging section to be charged with an ink which is heat-fusible but solid at ordinary temperatures and which is not water-soluble; a melting section for melting the ink; and a print head from which the ink melted in the melting section is jetted to record the back print. Using this back printer, one can produce sharp back prints of high quality without causing any adverse effects on the light-sensitive material A and yet good handling properties are assured.
