  • Patent number: 10983398
    Abstract: A manufacturing method for a liquid crystal display apparatus according to an embodiment of the present invention includes a step (A) of preparing a first substrate including a pixel electrode and a first photoalignment film that has not been subjected to an alignment treatment, and a step (B) of exposing a region of the first photoalignment film which is to serve as a first alignment region through a plurality of first photomasks, while transporting the prepared first substrate in a predetermined transport direction, the plurality of first photomasks including two or more first photomasks arranged in a second direction intersecting the transport direction. Each first photomask includes a plurality of pairs of a light-transmitting portion and a light-blocking portion.

  • Patent number: 10374478
    Abstract: In an electric motor, an n-th layer of windings includes: a first winding portion wound from a radially outer side of the stator to a radially inner side of the stator so as to form a gap dimensioned to one pitch or more of the windings at a preset position; and a second winding portion wound from the radially inner side of the stator to the radially outer side of the stator in a continuous manner from the first winding portion so as to fill in the gap, the second winding portion crossing the first winding portion. The gap is formed at a position that is at an intermediate portion of the tooth in a stator radial direction and that is a position at which the windings switch from the n-th layer to an (n+1)th layer.

  • Patent number: 7930320
    Abstract: An apparatus, a method, and a program for visualizing a Boolean expression so that it is readily recognized what is added to or excluded from conditions. A Boolean expression to be visualized is input in the form of a binary tree in which a leaf node represents an operand in the Boolean expression and a node other than the leaf node represents an operator in the Boolean expression. The input binary tree is transformed into a two-dimensional nested representation composed of a plurality of regions, and a pictorial representation for visualization is drawn on the basis of the nested representation and is displayed. When the Boolean expression is provided in a string expression, the string expression is transformed into a binary tree.
