Abstract: Ethylene-vinyl alcohol copolymers have superior gas barrier properties, but are inferior in bending fatigue resistance. The present invention improves bending fatigue resistance without reducing the gas barrier property and heat resistance. An ethylene-vinyl alcohol copolymer having an ethylene content of 20 to 50 percent by mole is modified by incorporating 0.01 to 1% mol of a structural unit expressed by the following formula (3): wherein, n indicates an integer of 2 to 5, m indicates an integer of 10 to 20, and R1 indicates a C1 to C20 aliphatic hydrocarbon group provided that R1 may contain a mercapto group, thioester group, sulfenamide, vinyl group, methacryloxy group, or acryloxy group. The modified ethylene vinyl alcohol copolymer may be used as a gas barrier resin and this gas barrier resin may be shaped or laminated and used in various applications such as in pneumatic tires and hoses.

Abstract: To improve the balance of the low temperature durability, gas barrier property, and melt processability of a thermoplastic elastomer composition comprising an aliphatic polyamide resin in which an ethylene-based modifying polymer is dispersed, a thermoplastic elastomer composition comprising a thermoplastic resin composition (A) and a modified ethylene-based modifying polymer (B) graft modified with acid anhydride groups, wherein the thermoplastic resin composition (A) comprises 60 to 90 percent by weight of a layered silicate modified aliphatic polyamide resin (A1) prepared by an interlayer polymerization method and 10 to 40 percent by weight of a hydrophobic plasticizer (A2) having a solubility parameter (SP value) of 10 to 12 (cal/cm2)1/2, the modified ethylene-based modifying polymer (B) is 70 of 120 parts by weight based on 100 parts by weight of the thermoplastic elastomer composition, and the modified ethylene-based modifying polymer (B) forms a dispersed particle phase.

Abstract: In a filament power supply circuit of a vacuum fluorescent display, an integration circuit is connected to a signal input terminal which receives a pulse signal having a magnitude corresponding to a DC power supply voltage. A comparison circuit compares an output voltage from the integration circuit with a reference voltage, and outputs a result. A first filament cathode connection terminal is connected to one terminal of the filament cathode of a vacuum fluorescent display and applies the DC power supply voltage to the one terminal. A second filament cathode connection terminal is connected to the other terminal of the filament cathode to ground the other terminal via a capacitive element. A three-terminal element includes first, second, and third terminals. The first terminal is connected to the first filament cathode connection terminal. The second terminal is grounded.
