Patent number: 8649019Abstract: A shape determining device includes first and second homodyne interferometers respectively provided for front and back surfaces of an object to be measured and a thickness distribution calculator that calculates a thickness distribution of the object based on intensities of first and second interference light beams respectively detected by the first and second homodyne interferometers for the front and back surfaces of the object at a plurality of measurement sites. The thickness distribution calculator calculates, for each interference light beam for which the intensity is detected by the first and second homodyne interferometers, a phase difference between the polarization components of a corresponding reference light beam and a corresponding object light beam in a corresponding non-interference light beam based on the intensity of the interference light beam, and calculates the thickness distribution based on a distribution of the calculated phase differences.Type: GrantFiled: January 28, 2010Date of Patent: February 11, 2014Assignees: Kobe Steel, Ltd., Kobelco Research Institute, Inc.Inventors: Masato Kannaka, Eiji Takahashi, Masakazu Kajita, Hideki Matsuoka, Hidetoshi Tsunaki, Noritaka Morioka, Kazuhiko Tahara, Takuya Atsumi

Publication number: 20120002213Abstract: An object of the present invention is to measure thickness distribution with precision by using a simple device configuration without being affected by vibrations of a to-be-measured object. In the present invention, for each of the front and the back surfaces of a to-be-measured object 1, each of light beams obtained by branching into two an emitted light beam from a laser light source 2 is further branched into two. Then, the light beams are reflected in reference surfaces and measurement points 1a and 1b mutually in a front and back relation, so that non-interference light beams Pax and Pbx each of which contains the reference light beam and the object light beam as mutually orthogonal polarization components are acquired. Then, each light beam is branched into a plurality. Onto one or more of the branched light beams, phase shift is performed in which a change is imparted to the phase difference between the orthogonal polarization components by using wavelength plates a261, a263, and a264 and the like.Type: ApplicationFiled: January 28, 2010Publication date: January 5, 2012Inventors: Masato Kannaka, Eiji Takahashi, Masakazu Kajita, Hideki Matsuoka, Hidetoshi Tsunaki, Noritaka Morioka, Kazuhiko Tahara, Takuya Atsumi

Patent number: 8001758Abstract: A single-layered rubber-product-reinforcing steel cord with good rubber penetration properties, excellent fatigue resistance, and small low-load stretch is obtained. All of wires 11 are provided with curls having a substantially elliptical cross-section and a pitch smaller than that of curls for intertwining, formed by providing the wires with spiral curls and then pressing the wires. These wires are intertwined into each other to form a single-layered twist structure, and, thus, a cord is obtained in which a hollow portion at the center of the cord is in communication with an outside via a gap 12 between the wires 11, and at least any one pair of adjacent wires 11 are substantially in contact with each other at any point in the longitudinal direction of the cord.Type: GrantFiled: March 18, 2010Date of Patent: August 23, 2011Assignee: Tokusen Kogyo Co., Ltd.Inventor: Noritaka Morioka

Publication number: 20090084489Abstract: A method of manufacturing a pneumatic tire according to the present invention can improve productivity. A steel cord S is continuously shaped in a helical manner or in a manner of a two-dimensional wave with at least one of amplitude and pitch of shaping of the steel cord varying in a phased manner or in a continuous manner just before winding of the steel cord S around a belt-forming drum 4. Then, the shaped steel cord S? is continuously wound around the rotating belt-forming drum 4 spirally in the circumferential direction of the drum in such a manner that the circumferential stiffness of a belt-reinforcing layer 16 varies in the widthwise direction of the tire.Type: ApplicationFiled: March 19, 2007Publication date: April 2, 2009Applicants: THE YOKOHAMA RUBBER CO., LTD., TOKUSEN INDUSTRY CO., LTD.Inventors: Shinya Harikae, Noritaka Morioka

Patent number: 7251922Abstract: A zero degree tire reinforcing steel cord is formed by twisting together four to seven individual wires having a wire diameter of 0.20 to 0.45 mm, wherein the steel cord has a substantially spiral or a substantially planar wavy deformation, has an elongation of 1.2% to 2.0% under a tensile load of 50 N and becomes substantially linear with its wavy deformation disappearing under a tensile load of 50 to 250 N. The steel cord stretches to a moderate extent so as to track expansion of the tire in the radial direction during the vulcanization process and thereafter restrains expansion of the tire in the radial direction during continued high speed rotation of the tire.Type: GrantFiled: March 28, 2002Date of Patent: August 7, 2007Assignees: Tokusen Kogyo Co., Ltd., The Yokohama Rubber Co., Ltd.Inventors: Noritaka Morioka, Sinya Harikae

Patent number: 7051506Abstract: A tire cord having core filaments (10) performed into a helical configuration while maintaining the core filaments (10) in a parallel, side-by-side relationship. The core filaments (10) are not twisted or stranded together. High tensile strength sheath filaments (11) are also performed into a flattened helical configuration so that the sheath filaments (11) can be wrapped around the side-by-side core filaments such that the sheath filaments (11) do not put such tension on the core filaments (10) as to cause the core filaments (10) to bunch. The core filaments (10) are maintained in a flat side-by-side configuration so that no voids are formed and rubber can penetrate into the tire cord. The core filaments (10) may number from three to six and the sheath filaments (11) from one to seven. The cross-section of the tire cord is flattened and confined within an oval-shaped outer bound (21), the oval outer bound (21) being characterized by a major axis and a minor axis.Type: GrantFiled: April 7, 2003Date of Patent: May 30, 2006Assignee: Tokusen U.S.A., Inc.Inventors: Takanori Kobayashi, William E. Smith, Charles E. Smith, Jr., Noritaka Morioka
