    Abstract: The liquid crystal composition is designed to improve light transmittance using an elastic constant and has a negative value of dielectric anisotropy (??), a liquid crystal display element using the liquid crystal composition, and the liquid crystal display. The liquid crystal composition has a negative value of dielectric anisotropy (??) and a value of ? of 0.28 or less. The value of ? is obtained from Equation (2) using a twist elastic constant (K22) value obtained from Equation (1) using measured values of dielectric anisotropy (??), a threshold voltage (Vth), a bend elastic constant (K33), vacuum permittivity (?0), a cell gap (d), and a helical pitch (P0) and measured values of a splay elastic constant (K11) and the bend elastic constant (K33).

  • Patent number: 9905346
    Abstract: A magnet chuck includes, for example, four permanent magnets of a first permanent magnet through a fourth permanent magnet, serving as an attracting and retaining member for attracting and retaining a workpiece. In the first permanent magnet and the third permanent magnet, the magnetic polarity of a workpiece magnetic attracting surface facing the workpiece is of an N-polarity. On the other hand, in the second permanent magnet and the fourth permanent magnet, the magnetic polarity of a workpiece magnetic attracting surface is of an S-polarity. More specifically, in this case, combinations of the N-pole and the S-pole on the workpiece magnet attracting surface are formed in two pairs, and the N-pole and the S-pole, which are of different polarities, are adjacent to one another.
