  • Patent number: 11514388
    Abstract: The purpose of the present invention is to provide a system which, in a product delivery procedure, monitors and manages, more simply and reliably, a deviation from a managed temperature during shipment. To solve the problem, provided is a logistics system, comprising: an information reading and transmitting device which reads an information code which is provided on a product and transmits data which is included in the information code; a server which accumulates, via a communications network, the data which is transmitted from the information reading and transmitting device; and a terminal device which refers to the data which is accumulated in the server via the communications network. The information code is formed from a pattern which changes with an occurrence of a deviation from a specified temperature. The system employs the information code.

  • Patent number: 9771436
    Abstract: The present invention provides a method for forming a polymer by using a mixture containing a polymerization initiator which is an adduct of a boron compound and a first unsaturated hydrocarbon compound, and a second unsaturated hydrocarbon compound, generating a radical by oxidization of the polymerization initiator and adding the radical to the second unsaturated hydrocarbon compound, thereby forming the polymer. According to the present invention, excellent controllability of alkylboranes for radical polymerization can be maintained and the structure of a polymerization initiation terminal can be freely selected and controlled. Thus, a terminal-modified polymer having functionality imparted to the terminal group can be prepared. In addition, a polymerization initiator having a plurality of polymerization starting points can be prepared, and polymers with special structures including multibranched polymers, grafted-type (comb-type) polymers and brush-shaped polymers can be prepared.

  • Publication number: 20140024765
    Abstract: An application to a resin material and a polymerization method of a polymerization agent having a polymerizable surface structure and a mechanism of supplying the polymerization agent, the polymerization agent exhibiting a polymerizing function in contact with the surface of the resin material. The resin material is obtained by living radical polymerization of a radical polymerization initiator exhibiting living property and an unsaturated monomer capable of radical polymerization with the polymerization initiator. The polymerization agent is brought into in contact with the surface of the resin material to induce radical re-polymerization of the polymerization agent. As a result, a damaged portion of the resin material can be repaired or the resin materials can be bonded to each other by way of the polymerization agent, which can suppress formation of the hetero-interface or improve the service life of the resin material.
