    摘要: An imprint lithography stamp includes a stamp body having a patterned surface and formed from a fluorinated ethylene propylene copolymer. The imprint lithography stamp further includes a backing plate with a plurality of through-holes with portions of the stamp body extending into the through-holes to adhere the stamp body to the backing plate. The patterned surface of the stamp body has a plurality of protrusions extending from the stamp body, which are used to form high aspect ratio features at high processing temperatures. A mold design for forming the imprint lithography stamp and an injection molding process for forming the imprint lithography stamp are also provided.

    摘要: Provided is a vehicle interior member that can suppress the reflection of light to the outside, and that can reduce glare from whatever angle a passenger views the interior member. A cross-section of a groove 6 formed in a vehicle interior member 4 is substantially V-shaped, and is constituted by two flat surfaces, a first reflection surface 7 and a second reflection surface 8. The groove 6 has a groove angle θ of 32 degrees, and the reflectance at a light receiving surface 5 is no more than 2.0%.

    摘要: A resin member includes: a resin substrate; and a micro-embossed pattern and having a plurality of recesses and a plurality of protrusions. The plurality of protrusions includes: a plurality of first protrusions; and a plurality of second protrusions having a height of from ¼ to ¾ of the height of the first protrusions. A distance between peaks of two adjacent ones of the plurality of protrusions ranges from 100 μm to 500 μm. The number of the minute regions having an angle of inclination of from −10° to 10° with respect to the reference plane ranges from 78% to 95% of the number of all of the minute regions included in the micro-embossed pattern corresponding to the predetermined distance, and the number of the minute regions having an angle of inclination of from −1° to 1° ranges from 25% to 40% of the number of all of the minute regions.

    摘要: A holding portion having a diameter larger than that of a cavity is formed in communication with the cavity, in an area of a two-part type mold, the area including a portion corresponding to an annular groove. Subsequently, an insert member formed in a cylindrical shape and provided with, on an outer circumferential surface, the annular groove having no step in a groove surface is fitted to the holding portion, and then the mold is closed. On an inner circumferential surface of the insert member, a surface treatment layer having a surface roughness rougher than those of other portions of the insert member is formed. Molten resin is injected into the cavity; thereafter, an assist material is injected into the cavity to mold the resin into a desired pipe body. Then, the insert member and the pipe body are integrated along with curing of the resin.
