Publication number: 20240361260Abstract: To provide an analysis method that can analyze a crystal structure, a crystal morphology, a crystal distribution of a rubber material in stretching even in a local portion of the rubber material. The present disclosure relates to a method of analyzing a crystal structure, a crystal morphology, or a crystal distribution of a rubber material in stretching using a nanodiffraction imaging technique that analyzes an electron diffraction pattern acquired by scanning electron beams converged to a diameter of 100 nm or less on a surface of the rubber material while a behavior of stretching deformation of the rubber material and/or a state of the rubber material in stretching are observed using a transmission electron microscope.Type: ApplicationFiled: March 28, 2024Publication date: October 31, 2024Applicants: TOHOKU UNIVERSITY, SUMITOMO RUBBER INDUSTRIES, LTD.Inventors: Hiroshi JINNAI, Tomohiro MIYATA, Daisuke WATANABE, Wakana ITO, Takehiro KITAURA

Patent number: 11827751Abstract: A nanonetwork with controlled chirality prepared via self-assembly of triblock terpolymers, wherein each of the triblock terpolymers includes a first block, a second block and a third block. The first block is connected to the second block, and the third block is connected to the second block. The first block, the second block and the third block are incompatible. The third block has a homochiral characteristic, and a chirality of the nanonetwork with controlled chirality is determined by the homochiral characteristic.Type: GrantFiled: October 14, 2021Date of Patent: November 28, 2023Assignee: NATIONAL TSING HUA UNIVERSITYInventors: Hsiao-Fang Wang, Po-Ting Chiu, Chih-Ying Yang, Zhi-Hong Xie, Yu-Chueh Hung, Jing-Yu Lee, Jing-Cherng Tsai, Ishan Prasad, Hiroshi Jinnai, Edwin L.

Patent number: 7960473Abstract: A thermoplastic resin composition includes a thermoplastic resin (A) and a reactive functional group-containing resin (B), which has a specific structure in the morphology of the resin composition observed by transmission electron microscopy tomography, and the relaxation time T1C of each carbon nucleus by the solid NMR measurement of the thermoplastic resin composition containing a polyamide resin is kept in a specific range. The composition is excellent in the balance between contradictory properties such as impact resistance and heat resistance, remarkably exhibits a peculiar viscoelastic behavior not observed in the conventional polymeric materials, and is remarkably excellent in impact energy absorbing performance and vibration energy absorbing performance at the time of high-speed deformation.Type: GrantFiled: March 22, 2007Date of Patent: June 14, 2011Assignee: Toray Industries, Inc.Inventors: Sadayuki Kobayashi, Daisuke Sato, Masaru Akita, Hiroshi Jinnai, Takashi Inoue

Publication number: 20110001251Abstract: Disclosed is an adhesive composition, comprising, as essential components, a thermosetting resin component A and a high-molecular component B which are evenly compatible and miscible with each other at a temperature of 5 to 40° C. without being separated from each other, and a curing agent component C, wherein after the adhesive composition comes into contact with an adherend and after the thermosetting resin component A is cured, the thermosetting resin component A is separated, in the adhesive composition, into particulate structures wherein the concentration of the thermosetting resin component A is larger than that in the surrounding of the particulate structures, and further the particulate structures are formed in a larger amount near a surface of the composition which contacts the adherend than inside the adhesive composition. The adhesive composition can be used in thin-film bonding.Type: ApplicationFiled: July 3, 2008Publication date: January 6, 2011Inventors: Yutaka Gou, Kazuhiro Miyauchi, Takashi Inoue, Atsushi Takahara, Hiroshi Jinnai

Patent number: 7675043Abstract: Left and right sides of the mesh sandwiching the placing region therebetween are set as left and right to-be-fixed portions to be fixed to sample holder separation portions respectively to be moved in a stretch direction. A slit for dividing use is formed from a portion of the periphery of the mesh disposed between the left and right to-be-fixed portions thereof toward the rubber slice-placing position of the mesh in a direction orthogonal to the stretch direction of the rubber slice or a direction inclined thereto. When the to-be-fixed portions are moved in a separation direction by moving the sample holder separation portions, the mesh is divided into left and right parts by the slit for dividing use so that the rubber slice fixed to the left and right sides of the mesh is stretched.Type: GrantFiled: October 4, 2007Date of Patent: March 9, 2010Assignee: Sumitomo Rubber Industries, Ltd.Inventors: Hiroyuki Kishimoto, Hirofumi Nakamae, Marina Kotani, Hidehiko Dohi, Hiroshi Jinnai, Takeshi Kaneko

Patent number: 6723392Abstract: A light-scattering sheet having a phase separation structure comprised of a plurality of solid components varying in refractive index is used to construct a liquid crystal display device. In a first embodiment, the light-scattering sheet is disposed in a defined position within a reflecting LCD device. Thus, in a reflecting LCD device comprising a liquid crystal cell constituted of a transparent front electrode plate having a substrate carrying a transparent conductive layer, a back electrode plate having a substrate carrying a conductive layer and a liquid crystal and, as disposed forwardly of the liquid crystal cell, a polarizer, the light-scattering sheet is interposed (i) between the polarizer and the front electrode plate or (ii) between the back electrode plate and a reflector disposed behind the back electrode plate. Alternatively, (iii) the substrate sheet may be constituted of the light-scattering sheet.Type: GrantFiled: November 29, 2000Date of Patent: April 20, 2004Assignee: Daicel Chemical Industries, Ltd.Inventors: Hiroshi Jinnai, Hiroyuki Takemoto, Hiroshi Takahashi, Masanori Hiraishi, Yoshiyuki Nishida
