Abstract: Decorative grass and methods of providing same are disclosed wherein the decorative grass is either maintained in flattened configuration until restraint is removed and/or the decorative grass is curled and/or crimp at a point of use and/or sale.

Abstract: A laser diode comprising a first separate confinement heterostructure and an active region on the first separate confinement heterostructure. A second separate confinement heterostructure is on the active region and one or more epitaxial layers is on the second separate confinement heterostructure. A ridge is formed in the epitaxial layers with a first mesa around the ridge. The first mesa is 0.1 to 0.2 microns above the second confinement heterostructure.

Abstract: In structures of the typical conventional photo couplers, an unwanted rotation or a dislocation during the manufacturing thereof is occurred during the manufacture of the couplers. The photo coupler according to the embodiment includes a lead frame (first lead frame), a lead frame (second lead frame) having an end section bent toward the lead frame, a light emitting element (first optical device) fixed to the lead frame, a light receiving element (second optical device) fixed to the lead frame so as to face the light emitting element, and an electrically insulating film, provided between the light emitting element and the light receiving element, and including an end section having protruding and contracting sections in plan view. An end section of the lead frame has protruding and contracting sections in plan view. Further, the end section of the electrically insulating film fits in the end section of the lead frame.

Abstract: A fuel cell system includes fuel cell stacks electrically connected in parallel and supplying a gross current to a load. A controller determines the gross load current, and produces a desired current through the load by adjusting, based on the gross load current, at least one parameter affecting at least one of the inputs to and outputs from the system. This system allows a stack design and its voltage output to be kept constant while stacks are added for increased power.

Abstract: An artificial turf system which includes a support layer, a base layer, and an outer layer. The support layer comprises an area of selected size and composition. The base layer comprises at least one grid which consists of a plurality of interconnected cells. The base layer is positioned over the support layer. Each cell forming the grid comprises an upstanding tubular member which includes an upper portion, having a first diameter, and a lower portion having a second diameter. The lower cell portion provides the cell with vertical flexibility. The plurality of cells provide the grid with selected vertical movement on contact providing the artificial turf system with improved softness.

Abstract: A method of making a porcelain flower includes the steps of extending a wire through an apertured finding, twisting the free ends of the wire, forming an amount of porcelain compound into a flat sheet, cutting the shape of a flower petal out of the flat sheet, and wrapping the flower petal around the twisted wires.

Abstract: A fabric having plant material adhered between layers of silk or hand-made paper. The silk or paper layers are translucent to allow the fabric to have the appearance of plant material. The fabric is manufactured by soaking dry plant material in water, pressing and drying the plant material to flatten it, adhering bottom and top layers of silk or paper to the plant material, and applying a stiffening agent to the fabric. Articles of various shapes may be formed by shaping the fabric into a predetermined shape prior to the step of applying the stiffening material.

Abstract: A woven conveyor belt splicing fabric of optimal strength, elongational and dimensional properties is produced by intermeshing relatively high tenacity and relatively high elastic modulus warp yarns (e.g., KEVLAR yarns) in a highly crimped one-by-one weave construction with nylon or other suitable filling yarns. The tenacity of the warp yarns provides high strength per unit fabric thickness while the crimp of the warp yarns provides a limited degree of initial stretchability of the fabric from a relaxed state sufficient to accommodate strain and deflective forces imposed on a conveyor belt splice during normal belt operation.

Abstract: The present invention relates to a new fabric which is rich in a new, raw material feeling which has been unparalleled before, a fashionable feeling and an unexpected feeling and to its method of preparation. The fabric of the present invention is a three dimensional fabric having a unique structure characterized by a structure wherein a mass of a number of apexes of piled fibers is made in a body to form a scaly structure and a number of said scaly structures cover the surface layer of the fabric.

Abstract: A packaging material comprising an outer layer of a heat shrinkable plastic film and a metallic glossy laminate which is disposed on the inner side of said outer layer and which maintains metallic gloss even after heat shrinkage. A heat shrunk package having beautiful metallic gloss can be obtained by the use of this packaging material.

Abstract: This invention relates to an optical information recording medium comprising a substrate provided at least with an underlayer and a recording layer thereon, said underlayer being prepared by curing a light-curable composition containing a reducing agent, a photo-polymerization initiator and acrylate monomer and/or methacrylate monomer and/or their corresponding oligomer.

Abstract: Woven or knitted fabrics of soft touch and elegant appearance composed of yarns including bundles of superfine fibers of less than 0.7 denier which are at least partly bound with a cured silicone polymer.
