Abstract: PURPOSE:To simplify the manufacturing process and to contrive reduction in cost of production by a method wherein both end parts or one end part of the cylindrical magnet body of a magnet roll are notched, and they are used as a supporting part. CONSTITUTION:A magnet roll 11 consists of a cylindrical roll part 12 located in the center part and supporting parts 13 and 13 located on both end parts, and they are formed in one body using resin magnet. The mixed material of high molecular polymer and the magnetic powder such as ferrite, rare-earth cobalt and the like, which is kneaded, molded and magnetized, is used as the above-mentioned resin magnet. As the end part of the roll part 12 constitutes the supporting parts 13 and 13 by notching the end part, the magnet roll 11 can be supported by merely providing a receptacle conforming to the supporting parts 13 and 13 on the developing unit of a duplicating machine.

Abstract: PROBLEM TO BE SOLVED: To provide a signboard which is extremely excellent in durability and is good in visibility. SOLUTION: The signboard 60 has a light transmission tube 70 of an inverted V shape indicating a character 'A' and a light transmission tube 71 of a straight line shape to be inserted in this V shape. The light transmission tubes 61 to 69 are drawn around horizontal so as to fill the circumference of the character 'A' and the spaces between the V shape. All of the respective light transmission tubes 61 to 69 and 70 and 71 are retracted on one side into a light source unit 80. Light emitting elements, such as LEDs, of 11 pieces in total, are installed in correspondence to the light transmission tubes 61 to 69 and 70 and 71. Respectively one piece of the light emitting elements are installed opposite to the end face of one piece of the light transmission tubes. All of the respective light emitting elements are driven by drive circuits so as to emit light independently from others.

Abstract: PROBLEM TO BE SOLVED: To maintain a high optical transmission tube function for a long period of time by fitting rings into the grooves on the inner peripheral surface of a metallic sleeve, thereby surely fixing end-sealing plugs and preventing the leakage or leaching of a core material. SOLUTION: The optical transmission tube 10 is provided with the grooves 5 around the end edge of a metallic sleeve 4 on the inner peripheral surface at the front end of the metallic sleeve 4 and the rings 6 fitted into the grooves 5 detain the end faces of the end-sealing plugs 3, thereby preventing the pull-out of the end-sealing plugs 3. The grooves 5 of the metallic sleeve 4 are formed to a square sectional shape and the rings 6 fitted into the grooves 5 are also formed to a square sectional shape so as to comply with the shape of the grooves 5. The transmission tube 10 is produced by inserting the end-sealing plugs 3 into the openings at both ends of the clad 2 packed with the core material 1, then fitting the metallic sleeve 4 previously mounted with the rings 6 in the grooves 5 in such a manner that the rings 6 come into contact with the end faces of the end-sealing plugs 3, then caulking the sleeve, thereby compressing and deforming the outer periphery parts of the metallic sleeve 4 and the clad 2.

Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive light transmission tube which emits light having high luminance while having directivity from its lateral peripheral surface, maintains an excellent light transmission characteristic in spite of adhesion of stains, etc., and has excellent mass productivity and which is excellent in executability. SOLUTION: This light transmission tube 1 has a tubular clad 3 and a core 2 composed of a material having the refractive index higher than the refractive index of this clad material, is formed with plural belt-like reflection layers 4 between the tubular clad 3 and the core 2 along the longitudinal direction thereof and is constituted to reflect and scatter the light passing the core 2 by these reflection layers 4 and to release the light from the outer peripheral surface of the tubular clad 3 on the side opposite to the side formed with the reflection layers. The outer peripheral shape of the cross section of the tubular clad 3 is noncircular. This light transmission tube may be produced by using a multicolor extruder.

Abstract: PROBLEM TO BE SOLVED: To surely prevent the occurrence of the liquid leak and the run of the core material in the vicinity of the calking section or the unplugging of a sealing plug or deviation and to maintain the optical transmission function over a long time by forming a film or a layer using the material having adhesiveness on the side surface of the sealing plug. SOLUTION: The timer side of a tubular clad 1 is filled with a transparent and liquid core 2 having the refractive index which is larger than the refractive index of the clad 1 and the both side opening sections of the clad 1 are plugged in by sealing plugs 3. The both side outer peripheral sections of the clad 1 are fitted with and covered by tubular metallic sleaves 4. Calking sections 5 of the sleaves 4 are calked and formed and the both side outer peripheral sections of the sleaves 4 are pressed and deformed. Moreover, a coating film 30 is formed over the outer peripheral surface of the plug 3. The plug 3 of the light incident side is formed from a transparent material. The light beams made incident from the plug 3 are transmitted to the core 2, reflected by the clad 1, transmitted to the other side direction of the core 2 and emitted from the other plug 3.
