Publication number: 20220332149Abstract: Provided is a pneumatic tire with which measurement of the strength of a magnetic field, which changes with wear, can be carried out regularly with stability and sufficient detection sensitivity so that the wear state of the tire can be ascertained regularly with accuracy. In this pneumatic tire, in a tread part where a pattern of protrusions and recessed grooves has been formed, a recess of a prescribed shape is formed in one or more of the protrusions so as to extend radially inward from the ground contact surface. A soft magnetic body formed by dispersing a granular soft magnetic material in a polymer material is embedded in the recess. A magnet formed using a hard magnetic material is provided radially inward from the soft magnetic body. A magnetic circuit formed by the soft magnetic body and magnet forms a magnetic field having a prescribed strength in the thickness direction of the protrusion.Type: ApplicationFiled: August 11, 2020Publication date: October 20, 2022Applicant: SUMITOMO RUBBER INDUSTRIES, LTD.Inventors: Hiroto SETOKAWA, Jun OCHI

Patent number: 7641973Abstract: A conductive layer of a conductive member for an image-forming apparatus is composed of a conductive polymer composition containing an ionic-conductive addition salt. The conductive polymer composition has a continuous phase and one or more uncontinuous phases including at least one first uncontinuous phase. The continuous phase and the uncontinuous phase form a sea-island structure. A salt capable of dissociating into cations and anions is unevenly distributed to the first uncontinuous phase. A polymer composing the first uncontinuous phase has a higher degree of affinity for the salt capable of dissociating into cations and anions than a polymer composing the continuous phase to prevent the salt (or the cations, the anions) from shifting out of the first uncontinuous phase or out of the polymer composition. The conductive polymer composition can contain melamine cyanurate so that it is flame-retardant.Type: GrantFiled: November 25, 2003Date of Patent: January 5, 2010Assignee: Sumitomo Rubber Industries, Ltd.Inventors: Takayuki Hattori, Kenichi Uesaka, Jun Ochi, Masakazu Tanaka, Katsumi Terakawa, Yogun Ki

Patent number: 5715754Abstract: An offset printing method is suitable for high-precision printing. Errors caused by the relative movement between a blanket cylinder 4 and a form plate 10 and the rotation of the blanket cylinder 4 on its axis which are produced in a step of transferring an ink image to the blanket cylinder 4 from the form plate 10, are reproduced in the relative movement between the blanket cylinder 4 and a surface to be printed on 11 and the rotation of the blanket cylinder 4 on its axis in a step for printing the ink image on the surface to be printed on 11 from the blanket cylinder 4. The dimensional errors produced in the ink image transferred to the surface 12 of the blanket cylinder 14 of the offset printing methods are cancelled when transferring the ink image from the surface of the blanket cylinder 4 to the surface to be printed on.Type: GrantFiled: July 19, 1996Date of Patent: February 10, 1998Assignee: Sumitomo Rubber Industries Ltd.Inventors: Jun Nishibayashi, Jun Ochi, Hiroaki Kawasaki
