Abstract: Provided is a cryopreservation container that prevents confusion of specimens to be used for treatment and that is suitable for individual management of fertilized eggs and the like to be cryopreserved. IC tags are attached to a cryopreservation tank 61, a canister 51, a cane 41, and cryopreservation containers such as an ovum storage container 1 and sperm storage containers 71, 81. The cryopreservation containers may also have individual identification codes attached hereto. An ovum storage container 11 is configured by fitting an IC tag 12 from the rear end of a rod-like part 2 of a conventional ovum storage container 1. In addition, the IC tag 12 is formed by providing an inlet 15 inside a thin-walled pipe 14 made of a synthetic resin. The inlet 15 may be fixed at both ends by means of fixing members 18, 18 composed of a nonconductive material, or may be integrally molded with a nonconductive synthetic resin material 20.

Abstract: Provided is an individual management system that prevents confusion of ova, fertilized eggs, and the like to be used for treatment, and that is suitable for individual management of fertilized eggs and the like to be cryopreserved. This individual management system comprises: a server 11 installed in an appropriate location within a facility; a plurality of personal computers 13, 21; identification code readers 14, 22, 34 that are used at appropriate location within the facility; an identification code/IC tag reader 47; a device, instrument, implement, and container 41, 42, 43, 45 that are used to cryopreserve specimens, as necessary; and identification codes and IC tags 43d, 45c that are attached to at least the device, instrument, implement, and container. The device, instrument, implement, and container installed or used within the facility are interconnected via an intra-facility network 5, and further connected to a cloud server 71 via the Internet 6.

Abstract: A bearing assembly includes an IC tag with information to be reliably exchanged between the IC tag and an external reader/writer, and a rolling bearing including outer and inner races and rolling elements disposed between the outer and inner races. The IC tag communicates with the external reader/writer device without contacting the reader/writer device, is attached to a metal member of the rolling bearing, includes a tag antenna, and is configured so information can be exchanged between the tag antenna and a reader/writer antenna of the reader/writer device by forming a closed magnetic circuit between the tag antenna and the reader/writer antenna. The IC tag is received in a hole in a metal member surface. The tag antenna includes at least two protrusions facing the opening of the hole and arranged so magnetic fluxes leaving/entering the protrusions pass inside the edge defining the hole opening and extend outside the hole.

Abstract: The present invention provides IC tags which can not easily be broken nor give any hazard to human health, which enables minimization of aborted tags, shortening of time required for deletion of recorded data, minimization of sanitary and environmental problems, and reuse of tags to substantially reduce the cost for a management system. A metal antenna and an IC chip are coupled to and integrated with each other to form an IC chip-mounted body. Then, the IC chip-mounted body is covered with ceramic cladding members to form an IC tag. The metal antenna is formed by winding a metal wire into a coil form. A ceramic filler is used for coupling the ceramic cladding members to each other and also tightly securing the IC chip-mounted body to the ceramic cladding members.

Abstract: A feed belt containing high hardness particles in an elastic material, the high hardness particles capable of being projected from a feed surface by elasticity of the elastic material when a member to be fed is fed, and the projecting amount being varied according to the shape or hardness of the member to be fed. 10 to 70 weight % of high hardness particles having a particle diameter of 3 to 300 &mgr;m are contained in an elastic material having a hardness corresponding to rubber hardness 15 to 90.

Abstract: There is provided a paper feed roller capable of being used for delivering and feeding paper, which is high in coefficient of friction, has sufficient hardwearing properties with the coefficient of friction not affected by the change in environment of temperature and humidity, is low in ink transferability and is small in change in passage of year of the coefficient of friction of the surface.A coating layer 5 formed of an elastic material such as rubber is formed on an surface of a core material 4 molded of a foamed material such as sponge, and a bonding agent 6 having an elasticity such as denatured silicon is coated on the surface of the coating layer 5 so that ceramic particles 7 are fixed without clearance to provide a paper feed roller 1. Alternatively, the bonding agent 6 is directly coated on the surface of the core material 4 molded of a pliable material such as soft rubber and sponge so that the ceramic particles 7 are fixed without clearance to provide the paper feed roller 9.
