Abstract: A prostate massage device (200) of the present invention includes: a base body (210); a rail support portion (230) formed on the base body; a rail (220) which is arranged to be inclined and supported at the rail support portion with a fixing shaft (231) interposed therebetween so that one end thereof is rotatable; a tension spring (233) which is biased to one end of the rail to be coupled to the fixing shaft and to lift the other end of the rail; a massage body (240) which moves along the rail; an arm (250) of which one end is linked with the massage body; an arm driving motor (260) which is linked with the other end of the arm to move the arm back and forth; and an upper cover (270) having a linear-type groove (271) so as to partially expose the massage body.

Abstract: Disclosed is a bio resin composition, a bio molded article, and a method of manufacturing the same. The bio resin composition is environmentally friendly and provides at least a predetermined level of physical properties, such as hardness, strength, and the like, by including a bio polyethylene resin, a thermoplastic olefin resin, a polypropylene resin, and an inorganic filter and by further including a thermoplastic rubber. The present composition reduces the generation of volatile organic compounds, and may increase the diversity of its use through injection molding.

Abstract: The present invention relates to an interior sheet for vehicles which includes a surface-treated layer which is formed from the electron beam cross-linking of a siloxane-modified urethane-based acrylate resin, silicone acrylate, and polysiloxane.

Abstract: The present invention provides an automobile interior sheet using a bioresin that includes: 5 to 100 parts by weight of a bioresin prepared from a starch extracted from at least one natural plant selected from the group consisting of corn, potato, sweet potato, sugar cane, bamboo, or similarities thereof; 30 to 100 parts by weight of a thermoplastic polyolefin (TPO) resin or a thermoplastic polyurethane (TPU) resin; 5 to 40 parts by weight of a compatibilizer; 0.1 to 1.5 part by weight of a lubricant; and 0.5 to 5 parts by weight of a crosslinking agent.

Abstract: Disclosed is synthetic leather, which includes and fabricated by laminating: a) a sheet made of PVC or polyurethane; b) a knit fabric having core yarn inserted between fabric weaves, a knit fabric knitted together with elastic yarn, or a knit fabric which has core yam inserted between fabric weaves and is knitted together with elastic yam. It is possible to provide synthetic leather, which replaces synthetic leather fabricated by laminating a PVC resin surface layer, a polyurethane foam cushion layer and a fabric layer using flame lamination process to fundamentally remove defect such as combustion gas and residual catalyst generated in flame lamination process of polyurethane foam and fabric and discoloration by monomer, improve rumples and twists generated in a sewed portion after sewing, and allow shortening of delivery date through shortening of process and removal of loss on process.

Abstract: Light beams are outputted from optical devices and mixed together to obtain uniform white light free from color stains, thereby achieving a backlight unit improved in light mixing feature. In the backlight unit, a surface light source has a reflecting surface with a plurality of optical devices mounted thereon. An optical sheet is disposed in front of the surface light source. A reflecting layer is disposed between the surface light source and the optical sheet and has reflectivity varied by an incident angle of light beams from the optical devices. The backlight unit enables the light beams from the optical devices to be mixed together. The light beams outputted from the optical devices are effectively mixed together by a reflecting layer having reflectively varied by an incident angle of the light beams from the optical devices, thereby achieving uniform white light without color stains.

Abstract: A surface light source capable of reducing color stains with reduced number of light emitting diodes and manufactured at low costs, and a liquid crystal display backlight unit employing the same. The surface light source includes a plurality of light source clusters arrayed along first and second directions, each of the clusters including three light emitting diodes disposed in a triangular arrangement, the three light emitting diodes including green, red and blue light emitting diodes. The surface light source also includes a first array of the clusters lined along and inverted alternately about the first direction; and a second array of the clusters lined along and inverted alternately about the second direction, where the first array is perpendicular to the second array. The invention reduces color stains to achieve uniform white light and reduces the number of light emitting diodes to manufacture a product at low costs.
