A method, system, and apparatus for an improved gripping device comprises a substrate and a curved microplate formed on the substrate. In certain embodiments, the system further comprises an array of curved microplates formed on the substrate further comprising a plurality of aligned rows of the curved microplates formed on the substrate and a plurality of aligned columns of the curved microplates formed on the substrate. The curved microplate has a gripping direction, being substantially opposite the direction of the curve in the curved microplate and the curved microplate has a releasing direction, substantially in line with the direction of the curve in the curved microplate.

Methods and apparatus for creating a large area imprint without a seam

Embodiments of the present disclosure generally relate to imprint lithography, and more particularly to methods and apparatus for creating a large area imprint without a seam. Methods disclosed herein generally include separating the curing time of the features in a stamp or product from the curing time of the seam and the periphery. The seam and periphery can be cured first or the seam and periphery can be cured last. Additionally, the seam curing operations can be performed on the master, on the stamp, or on the final product.

Production method of mold having recessed pattern in recessed step portion

A production method of a mold having a recessed pattern includes: a plate precursor preparation step of preparing a plate precursor having a pedestal on which a protruding pattern is disposed; a resin plate preparation step of preparing a thermoplastic resin plate having a recessed step portion; and a resin plate precursor production step of producing a thermoplastic resin plate precursor. The plate precursor comprises a substrate having a larger area than the pedestal in a plan view on a side opposite to a surface of the pedestal on which the protruding pattern is disposed. An edge portion where a side surface of the pedestal and the substrate are in contact with each other has a through-hole penetrating the substrate along the side surface of the pedestal.

METHOD FOR PRODUCING SILICONE ELASTOMER MOLDS
20230278264 · 2023-09-07 ·

Silicone compositions are described for the production of negative molds that include a silicone elastomer. The molds can be used in the production of molded articles.

Roll stamp for imprint device, and manufacturing method therefor

The present invention relates to a roll stamp and a method of manufacturing the same, the roll stamp including a cylindrical metal mold including a debossed pattern formed on an outer side and a hollow portion formed on an inner side, and a dummy roller inserted into the hollow portion. Because a joining portion is not formed on the entire area of the cylindrical metal mold, a problem in which edge regions are separated does not occur. Also, due to the absence of the joining portion, it is possible to perform a patterning process continuously.

ENTOMOLOGICAL TAXIDERMY PROCESS TO REINFORCE THE EXOSKELETON OF COLLEOPTERA AND MINIMIZE THE FRAGILITY OF A SPECIMEN FOR ITS LATER USE IN DECORATIVE APPLICATIONS

The present invention provides a mixture that serves for the preservation of Coleoptera to preserve its exoskeleton and its ornamental appearance; reinforce the exoskeleton of the coleopterous to minimize their fragility; improve the preservation of the insect by making an internal preparation that prevents rupture of the exoskeleton caused by blows, manipulation or pressure on it.

MASTER MANUFACTURING METHOD, MASTER, AND OPTICAL BODY

There is provided a new and improved master manufacturing method, master, and optical body enabling more consistent production of optical bodies having a desired haze value, the master manufacturing method including: forming a first micro concave-convex structure, in which an average cycle of concavities and convexities is less than or equal to visible light wavelengths, on a surface of a base material body that includes at least a base material; forming an inorganic resist layer on the first micro concave-convex structure; forming, on the inorganic resist layer, an organic resist layer including an organic resist and filler particles distributed throughout the organic resist; and etching the organic resist layer and the inorganic resist layer to thereby superimpose and form on the surface of the base material a macro concave-convex structure and a second micro concave-convex structure.

TRANSDERMAL DRUG DELIVERY PATCH AND MANUFACTURING METHOD THEREOF
20210228854 · 2021-07-29 ·

A transdermal drug delivery patch according to an exemplary embodiment of the present invention includes: a flexible base layer; and a plurality of microneedle disposed at one surface of the base layer. Each of the plurality of microneedles includes a biodegradable polymer and a drug and has an empty space inside. Each of the plurality of microneedles is formed as a star-shaped pyramid including a plurality of protrusions extending in a radial direction, and a part between two protrusions adjacent along the circumferential direction among the plurality of protrusions is concave.
