摘要:
A non directional pneumatic tire is provided for an agricultural irrigation system. The tire includes first and second side walls and a radially outer wall defining an internal inflation chamber. A non directional tread pattern is defined on the tire and includes a plurality of longitudinal protrusions positioned substantially parallel to a rotational axis of the tire. The longitudinal protrusions are arranged in first and second rows extending from the first and second side walls toward and across the equatorial plane of the tire. The longitudinal protrusions of the first and second rows circumferentially alternate with each other and there is a circumferential spacing between adjacent longitudinal protrusions at the equatorial plane so that no portion of one longitudinal protrusion circumferentially coincides with or overlaps another.

A screen includes a lens array having a plurality of spherical lens elements. A first length of the spherical lens elements, along a first direction at substantially a center of each of respective spherical lens elements, and a second length of the spherical lens elements, along a second direction at substantially the center of each of the respective lens elements and substantially orthogonal to the first direction, are set such that the second length is larger than the first length. A curvature center position of any one of the plurality of spherical lens elements is arranged to be at substantially a half of the first length along the first direction, with respect to a curvature center position of another spherical lens element adjacent to the lens element in the second direction.

A mold 6 for manufacturing a microlens substrate 1 is disclosed. The microlens substrate is provided with a plurality of microlenses each having a predetermined convex shape. The mold is used to press a base material of the microlens substrate to form the plurality of microlenses thereon. The mold 6 has a roll shape having an outer peripheral surface, and a plurality of concave portions 61 each having a predetermined shape corresponding to the convex shape of each microlens are provided on the outer peripheral surface of the mold 6 for pressing the base material of the microlens substrate. In this case, the plurality of concave portions 61 are formed by means of an etching process with a mask.

In a mobile phone remotely operating an information device, a communication unit receives information displayed on the information device. A display device displays a part of the information. A plurality of operation buttons respectively inputs an operation signal. A display control unit divides a screen of the display device into a plurality of cells, discriminately displays each of the plurality of cells on the screen, and displays a cursor on the screen. The cursor overlaps the part of the information on the screen. An operation control unit moves the cursor on one of the cells on the screen in response to the operation signal.

A member 6 with concave portions used to manufacture a member with convex portions is disclosed. Each of the member with concave portions and the member with convex portions has two major surfaces, and a plurality of convex portions are formed on one of the two major surfaces of the member with convex portions. The member 6 with concave portions includes: a first region 67 provided on one of the two major surfaces of the member 6 with concave portions, a plurality of first concave portions 61 being formed in the first region 67 and used to form the plurality of convex portions of the member with convex portions; and a second region 68 provided on the one major surface of the member 6 with concave portions, the second region 68 being located adjacent to the first region 67, a plurality of second concave portions 62 being formed in the second region 68, the depth of each of the plurality of second concave portions 62 being shallower than the depth of each of the plurality of first concave portions 61.
