20150054333 | Wheel with Tubeless Tire - A wheel includes a multi-layered rim, a sealing tape and a pressure-resistant tape. The multi-layered rim includes two layers. The first layer includes apertures for nipples. The second layer includes apertures corresponding to the apertures of the first layer. The sealing tape is used to wrap the second layer to seal the apertures of the second layer. The pressure-resistant tape is used to cover and support the sealing tape against high pressure. | 02-26-2015 |

20120301227 | FOUNDATION PILE AND INSTALLING METHOD THEREOF - A foundation pile includes a tubular wall, a top cap covering a top end of the tubular wall, a partition plate disposed transversely in the tubular wall below the top cap and dividing an inner space of the tubular wall into upper and lower spaces, two opposite fixing holes extending radially through the tubular wall and communicated with the upper space, and a plurality of pressure release holes extending radially through the tubular wall and communicated with the lower space. The partition plate prevents concrete slurry from flowing into the upper space. The pressure release holes allow the concrete to consolidate therein and to thereby increase transverse binding forces with the foundation pile. A method of installing the foundation pile is also disclosed. | 11-29-2012 |

20140240839 | OPTICAL SUBSTRATES HAVING LIGHT COLLIMATING AND DIFFUSION STRUCTURES - An optical substrate having a structured prismatic surface and an opposing structured lenticular surface. The structured lenticular surface includes shallow-curved lens structures. Adjacent shallow-curved lens structure may be continuous or contiguous, or separated by a constant or variable spacing. The lens structure may have a longitudinal structure with a uniform or varying cross section. The lenticular lenses may have a laterally meandering structure. Sections of adjacent straight or meandering lenticular lenses may intersect or partially or completely overlap each other. The lenticular lenses may be in the form of discontinuous lenticular segments. The lenticular segments may have regular, symmetrical shapes, or irregular, asymmetrical shapes, which may be intersecting or overlapping, and may be textured. The lens structure may be provided with isolated ripples, in the form of a single knot, or a series of knots. | 08-28-2014 |
20140367873 | Optical substrates having light collimating and diffusion structures - This invention discloses a method of forming an uneven structure on a substrate. Cut a plurality of trenches in an order on a surface of a mold through a control system, wherein the plurality of trenches comprise at least one first trench, wherein for any second trench of the at least one first trench, the second trench overlaps with at least one third trench different from the second trench such that the second trench is cut off by the at least one third trench. Use the surface of the mold to emboss a thin film on the substrate to form the uneven structure. | 12-18-2014 |
20150029729 | LUMINANCE ENHANCEMENT FILM HAVING A SUBSTRATE IINCORPORATION DISPERSED PARTICLES FOR DIFFUSION - The present invention discloses a light redirecting film. The light redirecting film comprises a support substrate and an optical substrate. The support substrate comprises a unitary body, wherein the unitary body has a first surface and a second surface opposite to the first surface. The optical substrate has a third surface and a fourth surface opposite to the third surface, wherein the fourth surface is a structured surface, and the second surface of the unitary body faces the third surface of the optical substrate. A plurality of particles are disposed in a region below the first surface of the unitary body, wherein the thickness of the region is smaller than the thickness of the unitary body. | 01-29-2015 |
