Spectacle lens production method and spectacle lens
A method for producing a spectacle lens 2 including a base portion 2 that is made of a resin material and includes a convex object-side face and a concave eyeball-side face, and an optical element 12 that is made of a material different from the material for forming the base portion and is embedded in the base portion, is described. The method includes: arranging an optical element in a cavity 28 of a mold including a first mold part 20 and a second mold part 24 that can be opened and closed; introducing a resin material for forming a base portion of the spectacle lens into the cavity of the mold; obtaining the spectacle lens by curing the resin material that is a resin for forming the base portion; disassembling the mold; and detaching the spectacle lens from the mold.
Imprint apparatus and method of manufacturing article
An imprint apparatus for performing an imprint process of forming a pattern of an imprint material on a substrate using a mold is disclosed. The imprint apparatus includes an adjustment unit configured to adjust a shape of the mold and a control unit configured to control the imprint process. The control unit obtains information indicating a tendency concerning a change of the shape of the mold corresponding to a use count of the mold used for the imprint process and controls the adjustment unit to correct the shape of the mold in accordance with the obtained information and a present use count of the mold. The control unit also controls the imprint apparatus to perform the imprint process after the shape of the mold has been corrected by the adjustment unit.
Imprint method and article manufacturing method
An imprint method includes arranging imprint material as droplets on shot region of substrate, bringing the imprint material on part of the shot region into contact with pattern region of mold and then enlarging contact region between the imprint material and the pattern region to whole region of the shot region, and curing the imprint material. in the arranging, in each of local regions located in radial direction from the part of the shot region, the imprint material is arranged such that directional drop density of the imprint material on line parallel to direction orthogonal to the radial direction and with droplets of the imprint material present thereon is smaller than that of the imprint material on line parallel to the radial direction and with droplets of the imprint material present thereon.
Imprint apparatus, imprint method, and method for manufacturing article
Provided is an imprint apparatus which reduces a shift of a mold from a desired position. The imprint apparatus that forms a pattern of an imprint material on a substrate using a mold includes a correction mechanism which corrects a shape and a magnification of the mold, and a control unit which controls the correction mechanism on the basis of a difference in shape and magnification between the mold and the substrate. The control unit changes a shape coefficient multiplied by a correction amount of the shape to balance a resultant force and a moment on the mold applied by the correction mechanism on the basis of a magnification coefficient, which is a coefficient multiplied by a correction amount of the magnification through closed-loop control.
Spray gun with faux carbon fiber pattern
A spray gun with a faux carbon fiber pattern comprises a main portion and an operating portion, at least one area of the main portion or the operating portion comprises a faux carbon fiber pattern, the pattern defined on a mold for the spray gun and formed directly on a surface of the spray gun during injection.
Template for imprint and imprint method using template
A template for imprint comprises a main body having a bottom surface, a middle surface on a portion protruding relative to the bottom surface, and a pattern surface on a portion protruding relative to the middle surface, the pattern surface having an uneven pattern, wherein an outer edge of the pattern surface has a jigsaw shape, wherein a light-shielding member having a light transmittance lower than a light transmittance of the main body is disposed on the middle surface to surround the outer edge of the pattern surface in a plan view as viewed from the pattern surface, and wherein an outer edge of light-shielding member defines four sides having a shape in which a center of each side bulges outward with respect to a rectangle surrounding the outer edge of the pattern surface in the plan view, and wherein the shape of each side bulges outwardly in a stepwise manner from the ends of each side to the center of each side.
IMPRINT APPARATUS AND ARTICLE MANUFACTURING METHOD
The present invention provides an imprint apparatus including a holding member configured to hold the mold, a spring member configured to connect the holding member to a base unit that supports the holding member, a driving unit provided between the holding member and the base unit and configured to drive the holding member in a vertical direction with respect to the base unit, and a regulating surface configured to regulate, in a vertical range in which the holding member is driven by the driving unit, a driving end on a side that is towards the base unit, wherein the driving unit performs a driving for pressing the holding member against the regulating surface, and in the driving, generates heat while pressing the holding member against the regulating surface.
IMPRINT MOLD, IMPRINT METHOD, AND MANUFACTURING METHOD OF ARTICLE
An imprint mold having an imprint surface that comes into contact with a curable composition on a substrate, the imprint mold includes a concavo-convex pattern formed on the imprint surface of the imprint mold, and a first step portion that has a first surface having a depth of 0.5 times or more and 2 times or less a depth of the concavo-convex pattern in an outer peripheral portion of an area where the concavo-convex pattern is formed.
TEMPLATE MANUFACTURING METHOD AND TEMPLATE BASE MEMBER
A template manufacturing method includes preparing a structure including a first substrate and a stacked body that is provided on the first substrate, the stacked body including a first lower layer including a first material, a first upper layer provided on the first lower layer including a second material different from the first material, and a first cover layer provided on a first cover region of the first upper layer and including a third material different from the second material. The method further includes forming a first resist layer on a portion of the first cover layer and on a first portion of the first upper layer, and exposing a second portion of the upper layer. The method yet further includes removing the second portion of the first upper layer using the first cover layer and the first resist layer as a mask.
INJECTION MOLDING DEVICE AND METHOD FOR INJECTION MOLDING
An injection molding device according to an embodiment of the present disclosure includes a first mold including a first injection port through which a raw material is injected; a second mold including a heating member; a first movable mold facing the first mold or the second mold and having a first cavity formed therein; and a second movable mold facing the first mold or the second mold and having a second cavity formed therein, wherein the position of the first movable mold and the position of the second movable mold can be changed.
