To provide a pipe inner-layer structure that allows inner surface materials to be accurately disposed, includes inner surface materials, simplifies installation work by saving labor in assembling component members, and has durability over a long period of time even after the completion of work, the pipe inner-layer structure of a pipe includes: fixed members 2 that are installed along an inner peripheral surface of a pre-installed pipe 1 at intervals in the pipe-axial direction of the pre-installed pipe 1; connection members 3 that are disposed on the fixed members 2 and include first fitting portions 31 to which an inner surface material 4 is fitted and second fitting portions 32 for installation to the fixed member 2; and the inner surface material 4 in the shape of a band, which is fitted to the first fitting portions 31 of the connection members 3 and is provided across fixed members 2 adjacent to each other in the pipe-axial direction. The connection members 3 are adapted so as to be divided and disposed on the fixed members 2 through the second fitting portions 32 included in the respective connection members 3.

An object of the invention is to provide a thin, low-power consumption, light-weight, and inexpensive surface light emitting apparatus using a hollow multilayer structure in combination with LEDs, and a method of light emission for the same. More specifically, the invention provides a surface light emitting apparatus comprising: a hollow multilayer structure formed from a plurality of hollow cells; a light source for emitting light into the hollow multilayer structure through an end face thereof containing a cell opening; and optical means for causing the light introduced through the cell opening-containing end face of the hollow multilayer structure to emerge from a surface of the hollow multilayer structure.

[Problem] To provide a light diffusing sheet which enables the light from a lightguide plate or light source of the backlight unit to be conducted to lens film after having been converted to diffused light having a small brightness peak angle, and which generates neither a moiré or interference fringe nor luminance unevenness, and is advantageous also from the standpoints of productivity and cost, and to provide a backlight unit having this light diffusing sheet incorporated therein. [Means for Solution] The invention is composed of a light diffusing sheet 10 comprising a light-transmitting resin, characterized by having fine recesses formed in at least one of the surfaces 2 thereof, the fine recesses 3 having a shape which is any of the shape of an inverted polyangular pyramid, the shape of an inverted truncated polyangular pyramid, the shape of an inverted cone, and the shape of an inverted truncated cone. brightness peak angle of diffused light is reduced, which restrains both a moiré and interference fringe, according to light refraction due to inclined face of fine recess 3 or a taper face. The invention is composed of a backlight unit characterized by including the light diffusing sheet and has been disposed on upper side of lightguide plate 20, or in front of a light source, so that that surface of the sheet which has fine recesses formed therein serves as a light emission side.

Flooring free from generating a noxioux gas, such as hydrogen chloride even when a fire occurs, suitably subjected to dry maintenance using a high-speed buffing machine, and having high scratch resistance, contamination resistance and abrasion resistance, and a remarkably high adhesion with respect to a floor ground surface, characterized in that the flooring is made by admixing an inorganic filler with a base material of olefin resin, and has a superficial layer containing at least 1-10 wt.% of wax. Preferably, the flooring has a rear surface layer laminated on the lower side of the superficial layer, formed by admixing an inorganic filler with a base material of an ethylene - vinyl acetate copolymer or a mixed resin of this copolymer and other olefin resin, and containing 1-10 wt.% of rosin. This flooring can be used extensively for office buildings, condominia, and transportation machines, such as vehicles, ships and aircrafts.
摘要:
A polymeric piezoelectric material including a polylactic acid molded article having been uniaxially drawn to an extent causing no fibrillation. The piezoelectric material exhibits piezoelectric properties equal to or higher than those of electret type or polypeptide type piezoelectric materials while having high enough mechanical strength to be processed into various articles ranging from films to profiles depending on the end use.
