| 20150115499 | SUMMIT DIAGONAL MATRIX FOR TIRE MANUFACTURE - A standardization system for the manufacture of tires is provided. The same size tire components can be used in the summit of tires having different sizes i.e., tires having different section widths, sidewall heights, and/or aspect ratios. A matrix of tire sizes can be associated with one or more tire summit parameters. The matrix can be used for the manufacture of tires having one or more standardized components by holding substantially constant the value of one or more tire summit parameters across a diagonal of the matrix. | 04-30-2015 |
| 20150137414 | Catalyst Composition and Method for Growing Spinable Carbon Nanotube Arrays - A method of forming an array of aligned, uniform-length carbon nanotubes on a planar surface of a substrate employing a composite catalyst layer of iron and cobalt. The carbon nanotubes have visible length and are useful for producing spun threads of carbon nanotubes having improved spinability and mechanical and electrical properties. | 05-21-2015 |
| 20150329685 | RELEASE FILM FORMED FROM POLYLACTIC ACID-CONTAINING RESIN - Polylactic acid-containing resin composition that includes a polylactic acid; and a (meth)acryl-silicone copolymer that includes a methyl(meth)acrylate; and a reactive silicone, wherein the (meth)acryl-silicone copolymer has a weight average molecular weight of 25,000 or more. Methods for producing a polylactic acid-containing resin composition, polylactic acid-containing resin films, polylactic acid-containing resin release films, polylactic acid-containing resin release films, and methods for producing polylactic acid-containing resin films are also disclosed. | 11-19-2015 |
| 20160001460 | EXTRUSION FORMING APPARATUS AND EXTRUSION FORMING METHOD - An extrusion forming apparatus includes an extruding section, a chamber drum, and a forming section. The extruding section kneads a material including a ceramic raw material and extrudes a kneaded material. The chamber drum has a first space portion having a first extruding direction extending portion through which the kneaded material is allowed to flow in an extruding direction, and a second space portion which has a second extruding direction extending portion extending in the extruding direction and a direction changing portion bending from the extruding direction to a downward direction, to allow the kneaded material to flow in the downward direction changed from the extruding direction. The second space portion has a cross section obtained by isotropically decreasing a cross section of the first space portion perpendicular to a flow-through direction of the kneaded material. The forming section has a die to extrude a ceramic formed body. | 01-07-2016 |
| 20160059502 | APPARATUS AND METHOD FOR MANUFACTURING RUBBER MEMBER - An apparatus for manufacturing a rubber member includes an extruder; a mouthpiece; and a support surface which faces the mouthpiece in an opposed manner. The apparatus further includes: a rubber pool portion formed between the mouthpiece and the support surface; and a closing surface having an inclined surface shape and capable of closing a moving-direction front side of the rubber pool portion. A rubber material is ejected from an ejection port in a state where the rubber pool portion is closed by the closing surface, the support surface and the mouthpiece are moved relative to each other after the rubber pool portion is filled with the rubber material, and a lamination starting end of the rubber material is pressed to the closing surface thus molding the lamination starting end into an inclined surface and, thereafter, the closing surface is moved in a direction away from the support surface. | 03-03-2016 |
| 20160075072 | COMPOSITE MATERIAL AND METHOD OF PREPARING THE SAME FROM SUBSTANTIALLY UNSORTED WASTE - A composite material having thermoplastic properties and comprising organic matter and optionally one or both of inorganic matter and plastic with unique characteristics is provided. Such a composite material may be prepared from waste such as domestic waste. For preparation of the composite material, waste is dried, optionally particulated. The dried and optionally particulated waste material is then heated, while mixing under shear forces. The composite material is processed to obtain useful articles. | 03-17-2016 |
| 20160129644 | APPARATUS FOR MODELING THREE-DIMENSIONAL OBJECT AND METHOD FOR MODELING THREE-DIMENSIONAL OBJECT - Provided is an apparatus for modeling a three-dimensional object configured to model a three-dimensional object by a fused deposition modeling, including a plurality of material resin supply units configured to supply filaments to be used as a modeling material, respectively, a mixed resin ejection unit configured to eject a mixed resin, which is obtained by mixing the filaments to be supplied from the supply units, and a control unit configured to control amounts of the filaments to be supplied from each of the supply units to the ejection unit. The supply units are configured to supply the filaments of different colors to the ejection unit, respectively, and the control unit is configured to control the amounts of the filaments to be supplied from each of the supply units to the ejection unit, thereby adjusting a color of the mixed resin that is to be ejected by the ejection unit. | 05-12-2016 |
