Abstract: A line-scanning optical printer, which forms an image on a sensitized sheet (25) by projecting a linear light having a given width and length thereto while successively scanning individual lines in the direction of the width, comprises a casing (50) having light shielding properties and including a window portion for radiating the linear light to the outside, a light emitting element (60), which substantially functions as a point light source and is stored in the casing, an optical system (72, 71, 73) for guiding light from the light emitting element (60) as the linear light to the window portion, and a liquid crystal optical shutter (80) attached to the window portion.

Abstract: The present invention relates to a method for treating fibrosis caused by excessive collagen deposition. The method involves administering Hepatocyte Growth Factors (HGFs). The HGFs accelerate the decomposition of the collagen when administered in an effective amount.

Abstract: The present invention uses LEDs as the light source in a optical printer employing a line scanning method in which an image is produced by relative motion of the light to a photosensitive medium. LEDs are arranged on a mounting substrate with LED pairs, each pair being of the same color, disposed symmetrically as to the center point of the line. Similarly, the power supply lead wires for the LEDs are also disposed symmetrically. In mounting the components on the mounting substrate, a light-intercepting material is used for intercepting light from the side faces of the LEDs.

Abstract: The present invention employs LEDs and a liquid crystal shutter driven in synchronization with the position of the photosensitive paper, thereby eliminating image distortion even where the head of the optical printer apparatus is subjected to unanticipated load during scanning by the head. A rotary encoder (320) is provided on the rotating shaft of the motor (310) that drives the optical head (100), and the drive timing for the LEDs (110) and the liquid crystal shutter (150) is synchronized with the output of the rotary encoder.

Abstract: The present invention relates to an agent accelerating collagen decomposition and a therapeutic agent for fibrosis disorder containing HGFs (Hepatocyte Growth Factors) as an active ingredient. The active ingredients HGFs accelerate the decomposition of collagen (increase of collagenase activity), and can effectively treat fibrosis disorder by the acceleration of collagen decomposition. Therefore, according to the present invention, the prevention and treatment of a disease due to reduced collagenase activity and fibrosis disorders characterized by excessive production of fibroblast-derived connective tissue matrix are possible.

Abstract: The present invention relates to a composite flexible hose excellent in pliability without any adhesive layer between an innermost layer and an intermediate rubber layer. The hose consists of the innermost layer, the intermediate rubber layer, a fibrous reinforcement layer and an external rubber layer, each of which is formed in this order from the inside. The innermost layer is formed of a modified polyamide obtainable by blending of a polyamide and a carboxyl-containing modified polyolefin, and the intermediate rubber layer is formed of a rubber composition obtainable by a blend of 10 to 50 parts by weight of silicic acid or a salt thereof and 5 to 15 parts by weight of a brominated alkylphenol formaldehyde resin per 100 parts of the rubber material obtainable by blending butyl rubber and a halogenated butyl rubber at a weight ratio of 50/50 to 0/100. The composite flexible hose is completed by vulcanization after laminating each layer.

Abstract: A process for producing a hybrid flexible having a synthetic resin core tube, a middle rubber layer, a braided fiber reinforcement layer and an outer rubber layer. The process includes a preparing step where the core tube is previously formed to a tube having an inside diameter less than a finished size, and the reinforcement is braided with a braiding angle less than rest angle, and a vulcanizing step where the hose is heated under a condtion that internal pressure is held in the synthetic core.
