Publication number: 20170137548Abstract: The present invention provides a polymer compound that can be expected to inhibit activation of a coagulation system, a complement system or a platelet system when brought into contact with in vivo tissue and/or blood since the compound is capable of containing intermediate water, and a composition and a device using the same. This problem is solved by a polymer compound containing a repeating unit represented by general formula (A), and used in contact with in vivo tissue and/or blood, in which in a process in which the polymer compound caused to contain water in a prescribed water content is cooled to ?100° C. and thereafter heated at a temperature rise rate of 5.0° C./min, a temperature region where exothermicity occurs is present in the range of ?80° C. or more and ?25° C. or less, and a temperature region where endothermicity occurs is present in the range of ?25° C. or more and lower than 0° C.: wherein R represents a hydrocarbon group having 1 to 20 carbon atoms.Type: ApplicationFiled: March 23, 2015Publication date: May 18, 2017Applicants: NATIONAL UNIVERSITY CORPORATION YAMAGATA UNIVERSIT Y, NOF CORPORATIONInventors: Masaru TANAKA, Atsushi NAGASAWA, Toshiaki TAKAOKA, Naoyuki AMAYA

Patent number: 6852780Abstract: Disclosed are optical materials which effectively absorb UV light up to the long wavelength band, have low specific gravity, and have balanced properties including impact and heat resistances; lenses; and optical material compositions as their starting materials. The composition contains a polymerizable monomer material consisting of at least one di(meth)acrylate of formula (1): (R: CH3 etc., Ph: a phenylene group; x, z: an integer of 1 to 5; y: 0 or 1) and at least one monomer (M) having at least one vinyl group in one molecule other than monomers of formula (1), and an additive selected from component (A1), (A2), or (B), or mixtures thereof, provided that components (A1) and/or (B) is contained, and when component (B) is contained, components (A1) and/or (A2) is also contained: (A1): a chlorinated benzotriazole UV absorber; (A2): a chlorine-free benzotriazole UV absorber; (B): a coloring agent having absorption maximum in 520-650 nm.Type: GrantFiled: November 20, 2001Date of Patent: February 8, 2005Assignee: NOF CorporationInventors: Takanori Fujita, Katsuyoshi Tanaka, Toshiaki Takaoka

Patent number: 6836814Abstract: According to the present invention, a serial control signal interface and a serial data interface are provided in addition to a USB interface having a USB device controller, and a switching circuit for selectively connecting these interface to a system connector is provided on a mobile communication terminal device. Then, when an external device is connected to the system connector, it is determined whether or not the external device has an external interface having a USB host function on the basis of the interface identification voltage supplied from the external device, so that the switching circuit is changed over on the basis of the determination result to select an appropriate interface.Type: GrantFiled: March 19, 2001Date of Patent: December 28, 2004Assignee: Kabushiki Kaisha ToshibaInventors: Toshiaki Takaoka, Kentoku Yamaguchi

Publication number: 20020160808Abstract: Either a first memory card (13) for storing subscriber's information indispensable for communication, such as information on contract with a communication carrier or information to identify the user as a subscriber or a second memory card (15) for mainly storing application programs is selectively connected to a mobile radio apparatus. When the second memory card is installed, a main control unit (16) transfers the subscriber's information stored in the first memory card to the second memory card. Based on the subscriber's information, the main control unit receives the incoming call signal from a base station and informs notice of an incoming call. To speak by telephone, the second memory card is replaced with the first memory card, which makes it possible to talk over the telephone. Therefore, it is possible to provide an expandable mobile radio apparatus that enables functions to be added at the user's request.Type: ApplicationFiled: August 27, 2001Publication date: October 31, 2002Inventors: Keiji Uehara, Toshiaki Takaoka, Koichi Ito
