Title: Paper conveying roller
Inventor: MATSUYAMA YASUO
IPC: H04N1/00
Filed: 1991-11-07
Abstract: PURPOSE:To reduce the extent of frictional load with a thermal head by forming the central part of a part conveying roller into a high frictional part, and forming both the ends into low frictional parts, respectively. CONSTITUTION:A high frictional part being slightly narrower in width than a minimum paper passing range is formed in a central part coming into contact with a sheet of recording paper 4 of an elastic member 2 of a conveying roller 1, and thereby this recording paper 4 is smoothly conveyed. In addition, a part coming into directly contact with a thermal head or the like of this elastic member 2 is used as a low frictional part 22, while any friction between the paper conveying roller 1 and the thermal head 5 or the like is made smaller, and when a paper size of the recording paper 4 is changed, if the elastic member 2 and the thermal head 5 are brought into direct contact with each other, only small frictional force is produced between them, and thus a variation in torque on the paper conveying roller 1 can be held down to the minimum.

Abstract: PURPOSE:To obtain plastic optical fibers having excellent oil resistance, gas resistance and heat resistance by causing an inorganic filler to be contained in at least a surface layer of a clad or jacket, and causing a metal plating layer to be applied onto this surface layer. CONSTITUTION:Using a mixture composition of a copper powder and a powder or pellets of a fluorine-containing resin and an olefinic resin, a tube having an inside diameter of 1.5mm and an outside diameter of 2.5mm is prepared with use of an extruder. Next, a monomer composition composed of 90g methylmethacrylate, 10g ethylene glycol di-methacrylate and 0.5 lauroyl peroxide is charged into the tube, and this composition is heated under pressure at 100 deg.C for one hour for polymerization. Then, the polymerized mass is heated under normal pressure at 120 deg.C for 8 hours and thus is completely polymerized to obtain optical fibers. Next, chemical copper plating is applied to the outer periphery of the optical fibers, i.e., the outside of the tube consisting of FEP and copper powder and thereafter electric copper plating is carried out with respect thereto.

Title: Internal pump
Inventor: KOMITA HIDEO
IPC: G21C15/243
Filed: 1992-11-30
Abstract: PURPOSE:To increase natural convection flowrate by widening flow area and reducing flow path resistance. CONSTITUTION:Around a diffuser 14, a bypass flow path 23 is provided. At the lower end of a pump shaft 9, a thrust disk 11 is provided and at the upper and lower surfaces of the thrust disk 11, thrust bearings 12a and 12b are provided. During operation of the internal pump, the pump shaft 9 receives upward thrust force and floats to the position that an impeller ring 24 blocks the bypass flow path 23. During the termination of the internal pump, the pump shaft falls by the self-gravity because of loosing the thrust force and the bypass flow path is opened. As the result, pressure loss decreases according to the increase of the flow area and natural flowrate also increases.

Title: Medium, structure and method for identification of objective
Inventor: HOSHINO SHUICHI
IPC: B42D15/10
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To make a forgery extremely difficult, and provide a high identification property, and make it suitable for articles which are generally distributed by a method wherein an identification medium in order to discriminate the genuineness of an objective is made a hologram wherein a high molecular cholesteric liquid crystal is provided on a reflective layer. SOLUTION: For a hologram foil 1, a bonding layer 2 to the surface of an objective, a cholesteric liquid crystal layer 3 as a reflective layer, a hologram forming layer 4 and a protective layer 5 are laminated. For example, by pressing by a hot stamp, the protective layer 5 which works as a release layer as well is separated from a base film by the pressure and heat, and is transferred to the objective A. If ad the hologram layer 4, a pattern of, e.g. a character or the like is recorded, a light which is cast from a light source is diffracted, and when being seen from a specified angle, the pattern is lightly seen in a specified color, and the genuineness can be judged. Normally, the design of the objective A can be seen as is being approx. transparent.  By this method, the identification property increases, and the degree of freedom in design on the surface of the objective A is not obstructed, and an identification in response to an application and a cost is possible, and the flexibility for general applications is increased.

Abstract: PURPOSE:To achieve a quick measurement by immobilizing an antigen treated by an enzyme and untreated one on a wall surface of the same reaction container to achieve a forecasting of a matter from a reaction pattern with a matter to be measured and to accomplish a plurality of reaction modes in the same reaction container. CONSTITUTION:A red blood cell 2 treated by an enzyme and untreated one 3 are immobilized on a wall surface of a reaction container 1. Then, after a sample is reacted in a reaction container, particles that are bonded specifically to a matter to be measured in the sample are placed into the reaction container. When the matter to be measured in the sample is an antibody against an antigen which will vanish by the enzyme treatment, particles 4 drawn to the wall surface of the reaction container 1 are bonded to the red blood cell 5 not treated by enzyme through an antibody 5 to form an agglutination mess. When the matter to be measured in the sample is an antibody against an antigen that will no vanish by the enzyme treatment, the particles are bonded both to the red blood cells 2 and 3 through antibodies 5 and 5' to form an agglutinated mass expanding evenly on the wall surface. This enables measurement of the presence of two types of matters to be measured in the sample with the same reaction container.

Abstract: PROBLEM TO BE SOLVED: To obtain the amount of vibration efficiency by allowing a projection part to hit against a shaft bending prevention part when a rotary shaft is bent. SOLUTION: In a shaft bending prevention part 9, a projection part 8 is arranged at its inner diameter. A gap part 10 is provided between the shaft bending prevention part 9 and the projection part 8. The distance to the gap part 10 is set so that the shaft bending prevention part 9 hits against the projection part 8 before a rotary shaft 4 is subjected to bending deformation and reaches a plastic deformation region exceeding an elastic deformation region. A rotary center is that of a weight 3. One portion of the projection part 8, that of the rotary shaft 4, and a part for covering the rotary shaft 4 of the weight 3 are located at the opposite side of the center of gravity of the weight 3 out of the rotary part of the vibration motor 1 with the rotary center as a reference.  These parts reduce the amount of eccentricity of the weight 3 and vibration being generated by the vibration motor 1. The protrusion part 8 and the rotary shaft 4 reduce a part being connected to the weight 3, thus obtaining vibration from the vibration motor 1 more efficiently.

Abstract: PURPOSE:To increase the durability of a coiled spring and to improve the reliability by providing a coiled spring stored in a storing portion, both ends of which are respectively fixed to the first and second flywheel portion sides to connect both fly wheels in the torsional direction and a lubricating oil supply means for the storing portion. CONSTITUTION:A coiled spring 38 for elastically connecting the first and second fly wheel 16, 20 portions in the torsional direction to each other is stored in a storing recess portion 28 concentric with a crankshaft 12, and both ends of the coiled spring are fixed to the first and second fly wheel 16, 20 portion sides. Accordingly, even if the fly wheels 16, 20 are rotated at high speed, the centrifugal force does not work on the coiled spring 38 and does not cause deformation. As lubricating oil is supplied to the interior of the storing recess portion 28 by a supplying means, even if the coiled spring 38 is deformed to be in contact with the peripheral wall, abrasion is prevented by the presence of the lubricating oil so as to increase the durability of the coiled spring 38 and improve the reliability.
