  • Patent number: 10689217
    Abstract: An inclination of an outer circumferential surface of a film roll with respect to a widthwise axis is restricted. The roll includes: an outer cylinder part having a material thickness that is smaller toward a negative side of a y-axis than it is toward a positive side of the y-axis; and a slit separator which is wound around an outer circumferential surface of the outer cylinder part and which has a thickness that is larger toward the negative side of the y-axis than it is toward the positive side of the y-axis.

  • Patent number: 10677587
    Abstract: In regard to at least one of long separator sheets (12a, 12b), measurement is carried out to measure the amount of curl at an edge of the at least one of the long separator sheets (12a, 12b) while applying tension to the at least one of the long separator sheets (12a, 12b) in the lengthwise direction (MD) of the at least one of the long separator sheets (12a, 12b), the edge being parallel to the lengthwise direction (MD) of the at least one of the long separator sheets (12a, 12b). This makes it possible to provide a method of measuring the amount of curl in a separator, a slitting apparatus, and a curl amount measuring apparatus, each of which is capable of carrying out a highly accurate nondestructive measurement of the amount of curl without having to cut a sample from a long separator sheet.

  • Publication number: 20110285939
    Abstract: The present invention aims to provide a liquid crystal display capable of providing natural color display not tinged with red when viewed from an oblique front direction as well as when seen from a direct front direction. The liquid crystal display device of the present invention includes a light diffusing optical member (3), a light source (2) arranged on a rear surface side of the optical member (3), and a VA type liquid crystal panel (30) arranged on a front surface side of the optical member (3). The light diffusing optical member (3) is made of a transparent material in which light diffusing particles are dispersed. A relational expression of 0.01??n×D50?0.25 is satisfied, where ?n is an absolute value of a difference between a refraction index of the transparent material and a refraction index of the light diffusing particles, and D50 (?m) is an accumulative 50% particle diameter of the light diffusing particles.
