  • Publication number: 20240076425
    Abstract: To provide a 4-methyl-1-pentene polymer being excellent in storage stability when dissolved in a solvent and solubility, and being excellent in at least one of heat resistance, and a coating appearance when a coating film is stretched, for example, when such a film is bended or used in a flexible application. A 4-methyl-1-pentene polymer (A) being a copolymer of 4-methyl-1-pentene and at least one selected from linear ?-olefins having 6 to 20 carbon atoms, the 4-methyl-1-pentene polymer (A) satisfying the following requirements (I) and (II): (I) an endotherm end temperature (TmE) in a melting (endothermic) curve measured by DSC is 230° C. or lower; and (II) an exotherm start temperature (TcS) in a crystallization (exothermic) curve measured by DSC is 210° C. or lower.

  • Patent number: 11731340
    Abstract: An apparatus includes a first roll and a second roll on each of which a pattern is formed, a first motor and a second motor to rotate the respective rolls, a shaft direction supporting mechanism to support the second roll along a shaft direction and an axial position adjusting mechanism configured to move the shaft direction supporting mechanism along the shaft direction. The posture of the rotating shaft of the second motor is maintained constant at all times, and the second roll is moved in the shaft direction along the first roll, thereby adjusting the positions of both patterns on the first roll and the second roll along the shaft direction.

  • Publication number: 20170282418
    Abstract: According to one embodiment, a rotating state of a second motor is transmitted to a second roll as it is. A posture of a rotation central axis of the second motor is maintained constant. A changed state of the second roll is not transmitted to the second motor. Thereby, the second roll is rotated with timing identical to the rotating state of the second motor.

  • Patent number: 7846367
    Abstract: A sheet or film-forming roll has an inner cylindrical member and an elastic outer cylindrical member. The inner cylindrical member has a pressure chamber therein. As the inner cylindrical member becomes deformed (crowing change) depending on a pressure value of incompressible fluid led to the pressure chamber, the elastic outer cylindrical member becomes deformed (crowing change) too.
