Abstract: A display including a plurality of pixels each including a plurality of first subpixels and a plurality of second subpixels. In pixel, when illumination light is applied to the first subpixels from a normal direction, no diffracted light emerges from the plurality of first subpixels, or first diffracted light emerges from the plurality of first subpixels in a first angular range. When illumination light is applied to the second subpixels from the normal direction, no diffracted light emerges from the plurality of second subpixels, or second diffracted light having a wavelength equal to that of the first diffracted light emerges from the plurality of second subpixels in a second angular range wider than the first angular range, at an intensity lower than that of the first diffracted light; with the pixels configured to display a continuously changing image using the first diffracted light and the second diffracted light.

Abstract: An embodiment of the present invention is an antiglare film which includes an antiglare layer having particles A, particles B, and a binder matrix on a transparent substrate. A difference in refractive index between the particles A and the binder matrix (|nA?nM|) is 0.060 or less. A difference in refractive index between the particles B and the binder matrix (|nB?nM|) is in the 0.080-0.300 range. An average diameter (unit: ?m) of the particles B (rB) is in the 0.5-5.0 ?m range. The product value |nB?nM|wBH, which is obtained by multiplying a difference in refractive index between said particles B and said binder matrix (|nB?nM|) by a content (part by weight) of said particles B as against 100 parts by weight of said binder matrix (wB) and an average thickness (unit: ?m) of said antiglare layer (H) is in the 10.0-15.0 range.

Abstract: A light reuse sheet includes a reflective surface having an uneven configuration, the reflective surface in order to reflect light in a specific direction so as to cause light to be incident to a solar battery cell, the light being incident to a solar battery module, or in order to exit light in a specific direction by reflecting the light, the light being emitted from a light emitting element of a light source module.

Abstract: The present invention provides an antiglare film which has (1) appropriate antiglare properties in a frontal direction, (2) no white-blurring (3) no surface appearance such as a kind of orange on the surface of an antiglare layer's side. It is a feature of the antiglare film of the present invention that it has an antiglare layer on a transparent substrate and the antiglare layer includes a binder matrix and particles of an acrylate-styrene copolymer. In addition, the binder matrix includes an acrylic material having a hydroxyl group, a quotient (RA/H) obtained by dividing the average diameter of the particle (RA) by the average thickness of the antiglare layer (H) is in the range of 0.30-0.

Abstract: It is possible to eliminate the problem that a conductive part to a light source is subjected to stress by operation of a needle-pointer, thereby improving reliability. A needle-pointer type meter includes: an indicator plate having a first see-through portion and an indicator portion surrounding the first see-through portion; a rotary body having a second see-through portion corresponding to the first see-through portion; a drive device for moving the rotary body; a needle-pointer mounted on the rotary body and moving along the indicator portion around the first see-through portion; light sources illuminating the needle-pointer; and a display device for displaying predetermined information to an observer via the see-through portions. A plurality of light sources are arranged at an interval along the movement route of the needle-pointer. The needle-pointer is made of translucent material which emits light when receiving light from a predetermined light source of the plurality of light sources while moving.

Abstract: An exhaust purifying device applicable to an exhaust system extending from an internal combustion engine has a casing and a core received in the casing. The core has a honeycomb structure implemented by a corrugated sheet metal and a flat sheet metal rolled up together in a spiral configuration. Part of the flat sheet forming the outer periphery of the core is formed with a plurality of openings. The core is locally affixed to the casing by a solder applied to the portions of the flat sheet surrounding the openings and opposite edges of the flat sheet. This is successful in surely and stably affixing the core to the casing despite that the solder is implemented as an inexpensive powdery solder.

Abstract: An exhaust purifying device for reducing toxic components contained in an exhaust emanating from an internal combustion engine. The device has a casing connected at both ends thereof to an exhaust system extending from the engine, and a core received in the casing and provided with a honeycomb structure constituted by a corrugated sheet and a flat sheet which are rolled up together in a spiral configuration. A pair of retaining members are received in axially opposite ends of the casing for preventing the core from moving in the axial direction and circumferential direction relative to the casing. Each of the retaining members radially traverses the associated end of the casing and includes a biting portion slightly biting into the associated end of the core.

Abstract: Method and apparatus for enabling fluid material contained in a package to be examined in a non-destructive manner to see whether there is any unacceptable alteration in the material. This examination is accomplished by shaking the package so that the package and its contents vibrate at the natural resonance frequency thereof, exposing the package to an irradiation of ultra-soft X-ray beams while the package is vibrating at the resonant frequency, either immediately after the package contents begin to be agitated by shaking or immediately after the vibration is stopped and it ceases to be agitated, detecting the strength of X-rays transmitted through the package and its contents, coverting the transmitted X-rays to a corresponding analog signal, and determining any alteration by comparing the analog signal against the refernece signal previously obtained in the same manner as described above for a like package with unaltered contents.

Abstract: In a display managing arrangement comprising a display memory and a display memory controller for accessing the display memory to display a selected area of an image datum with the selected area scrolled on the image datum or otherwise subjected to management, the display memory is divided into memory blocks arranged as an N-row M-column matrix. Each memory block is for use as a unit of the management and is divisible into memory elements arranged as an n-row m-column matrix.
