Patent number: 9144415Abstract: The carotid artery plaque properties are quantitatively determined by a carotid artery echo whereby predicting incidence of cerebral infarction or myocardial infarct. A method includes obtaining, coloring, and displaying steps. In the obtaining step, the integrated amounts per unit time of echo signals corresponding to pixels of an echo image of carotid artery plaque are obtained. The signals are obtained when the image is obtained by an IBS method. In the coloring step, the relationship between ranges and colors is referenced. The available full range of the integrated amount is previously divided into the ranges. The colors are assigned to the ranges. The pixels are classified into the ranges in accordance with the integrated amounts corresponding to the pixels. The pixels of the image are colored in colors corresponding to the ranges of the pixels. In the displaying step, the colored echo image is displayed on a display portion 30.Type: GrantFiled: January 31, 2011Date of Patent: September 29, 2015Assignee: THE UNIVERSITY OF TOKUSHIMAInventors: Masataka Sata, Hirotsugu Yamada

Publication number: 20150247013Abstract: Disclosed herein is a film that exhibits well-balanced physical properties such as high surface hardness, excellent transparency, excellent cracking resistance, and excellent anti-whitening on bending when laminated on a plastic molded body, and is therefore suitable for decorative molding applications. The film is an acrylic resin film obtained by forming, into a film, an acrylic resin composition containing an acrylic resin and a rubber-containing graft copolymer, the rubber-containing graft copolymer being obtained by polymerizing monomer components (B-1) to (B-4) in order so that rubber particles obtained by polymerizing (B-1) to (B-3) have an average particle size of 0.2 to 0.4 ?m. The monomer component (B-1) comprises 40 to 100 wt % of an acrylate, 60 to 0 wt % of a monofunctional monomer copolymerizable therewith, and 0.05 to 10 parts by weight of a polyfunctional monomer.Type: ApplicationFiled: September 11, 2013Publication date: September 3, 2015Inventors: Haruki Koyama, Hirotsugu Yamada, Fuminobu Kitayama, Katsumi Yamaguchi
