  • Publication number: 20190329594
    Abstract: In a pneumatic tire, a carcass layer mounted between bead portions includes composite cords made of polyethylene terephthalate fiber yarn having a fineness from 420-1200 dtex and an aromatic polyamide fiber yarn having a fineness from 520-1200 dtex, and a total fineness from 940-2400 dtex, and a twist coefficient from 1600 to 2400, the composite cords having an intermediate elongation from 2.0% to 4.5% with a load of 2.0 cN, having a dimensional stability index from 2.5% to 6.0% which is a sum of a dry heat shrinkage rate at 150° C. and the intermediate elongation with the load of 2.0 cN, and having a ratio of an initial elastic modulus at 100° C. within a load range from 0 N to 44 N with respect to an initial elastic modulus at 25° C. within a load range from 0 N to 44 N, the ratio being from 76% to 94%.

  • Publication number: 20180154695
    Abstract: A pneumatic tire has a tire skeleton portion in which a plurality of arranged reinforcing cords are covered by a rubber layer. The reinforcement cords are organic fiber cords formed from polyethylene terephthalate. The organic fiber cords have an intermediate elongation (2.0 cN/dtex) of 3.0% to 4.0%, a dimensional stability index of 5.0% to 6.5%, and a difference between an elongation ratio at a strength at 70% the strength at the time of breaking and an elongation ratio at the time of breaking in a strength-elongation curve of 11% to 16%.

  • Patent number: 9632117
    Abstract: An electron beam detecting device detects a state of an electron beam radiated by an electron beam radiation device. A plurality of wire electrodes, which are conductors, are disposed corresponding to a plurality of filaments, the wire electrodes being electrically insulated from each other, in the area in which the electron beams are radiated. The electrical current flowing through each of the wire electrodes is measured by an electric current measuring instrument (measuring unit). A CPU (determining unit) determines the radiation level of the electron beams by receiving a signal output by the electric current measuring instrument. The CPU judges that when the measuring instrument measures a decrease of the current value, an abnormal condition exists in the filament corresponding to the conductor with the lower current value.

  • Patent number: 5758980
    Abstract: A portable tape printer having a reduced size. A control board and a cassette are positioned in vertically superposed relation within a case. A cut-away portion is formed at a broad surface of the control board and at one longitudinal end portion of the control board. A drive motor is disposed in a cut-away space. Thus, the drive motor is positioned at one longitudinal end portion of the control board. Further, a battery portion installing therein dry batteries is positioned at another longitudinal end portion of the control board. Reduction in size and weight balance result.
