Disclosed are methods for forming a double-sided optical sheet, and a vehicle lamp assembly having the double-sided optical sheet integrated therein. A first optical pattern is imprinted on a first side of a material, and a second optical pattern is imprinted on a second side of the material, opposite the first side. The first and second optical patterns are thereby formed on opposing sides of the same sheet. When oriented adjacent a light source, the double-sided optical sheet homogenizes light emitted from the light source. For a light source having a plurality of lighting elements, the double-sided optical sheet is configured to blend light emitted from the plurality of lighting elements to form one homogenous beam of light output resulting from a single light-modifying member.

Systems and methods for shaping a film. Formable material in an imprint field on the substrate may be contacted with a shaping surface of a template. Outer boundaries of the imprint field correspond to outer boundaries of the shaping surface. Shaping the film includes forming a cured layer within the imprint field while the shaping surface is in contact with the formable material. Shaping the film may include separating the shaping surface from the cured layer. Shaping the film may include moving the template away from the imprint field to a first offset location wherein the outer boundaries of the shaping surface are offset relative to the outer boundaries of the imprint field. Shaping the film may include curing a second portion of the formable material while the template is at the first offset location so as to form the shaped film.

An imprint apparatus that forms a pattern on a substrate by using a mold, the apparatus comprises a supply unit configured to supply an imprint material to the substrate; a contact unit configured to contact the imprint material that has been supplied to the substrate with a mold; a substrate stage configured to move the substrate; a gas supply unit that is provided between the supply unit and the contact unit, and supply gas toward the substrate; and a flow volume adjustment unit configured to adjust a flow volume of the gas that is supplied from the gas supply unit, while the substrate stage moves the substrate from a supply position at which the imprint material is supplied by the supply unit to a contact position at which the imprint material is contacted with the mold by the contact unit.

A fiber-reinforced resin shaped product includes: reinforcing fibers with a weight average fiber length of 100 mm or less; and a thermoplastic resin. The fiber-reinforced resin shaped product has grains on at least a part of a surface thereof. A maximum height (Rz) of the grains is 100 m to 200 m, and an average pitch (Rsm) between adjacent grains is 1100 m or less.

An imprint apparatus that forms a pattern on a substrate by using a mold, the apparatus comprises a supply unit configured to supply an imprint material to the substrate; a contact unit configured to contact the imprint material that has been supplied to the substrate with a mold; a substrate stage configured to move the substrate; a gas supply unit that is provided between the supply unit and the contact unit, and supply gas toward the substrate; and a flow volume adjustment unit configured to adjust a flow volume of the gas that is supplied from the gas supply unit, while the substrate stage moves the substrate from a supply position at which the imprint material is supplied by the supply unit to a contact position at which the imprint material is contacted with the mold by the contact unit.

An imprint apparatus includes a mold holder that holds a mold, a substrate holder that holds a substrate by suction, a driving device that brings the mold into contact with an imprint material on the substrate by relatively bringing the mold holder and the substrate holder close to each other, and a controller. The controller controls the driving device so as to bring the mold into contact with the imprint material in a state in which the substrate is deformed into a convex shape with respect to the mold by controlling pressures inside the plurality of suction regions based on surface shape data of the substrate held by the substrate holder.

Methods for mass production of new microfluidic devices are described. The microfluidic devices may include an array of micro-needles with open channels in fluid communication with multiple reservoirs located within a substrate that supports the micro-needles. The micro-needles are configured so as to sufficiently penetrate the skin in order to collect or sample bodily fluids and transfer the fluids to the reservoirs. The micro-needles may also deliver medicaments into or below the skin.

The present invention relates to a method and a structure for attaching nonslip members to both sides of a sock, in which nonslip members having a variety of patterns may be firmly attached to an inner side and an outer side of a sock, which need a nonslip member, using a mold, the nonslip member includes air holes to be smoothly ventilated, and a size of the nonslip member is adequately adjusted according to a thickness and an area of the mold.

An imprint apparatus for forming a pattern of an imprint material on a substrate using a mold includes a plurality of alignment scopes and a control unit. The control unit controls aligning of a shot region of the substrate and the mold based on outputs from the plurality of alignment scopes. Each of the plurality of alignment scopes outputs information indicating a relative position of a first mark selected from a plurality of first marks in the shot region and a second mark selected from a plurality of second marks on the mold. The control unit controls aligning of the shot region and the mold based on information excluding incorrect information from a plurality of pieces of information output from the plurality of alignment scopes.

The present invention provides an imprint apparatus that performs imprint processing of forming a pattern of an imprint material on a substrate using a mold, the apparatus including an image sensing unit configured to sense at least one of the mold and the substrate and obtain an image, and a determination unit configured to determine normality/abnormality of the imprint processing, wherein the imprint processing includes a first step of supplying the imprint material onto the substrate, and a second step of bringing the mold and the imprint material on the substrate into contact with each other, and the determination unit changes a reference of determination of the normality/abnormality of the imprint processing for each step of the imprint processing and determines the normality/abnormality of the imprint processing based on the image sensed by the image sensing unit.
