摘要:
The present invention relates to a method of discovering optimal conditions such as the rotational speed ratio of an abrasive cloth and a dresser, to improve the flatness of the abrasive cloth after it has been dressed. A narrow annular dresser having an inner diameter of at least the width of a wide annular utilization region of the abrasive cloth is pressed while rotating against the abrasive cloth which is fixed onto a turn table. A rotational motion is imparted to the abrasive cloth in the same direction as the rotation of the dresser and at a predetermined rotational speed. The abrasive cloth is dressed thereby in such a manner that there is a uniform distribution of distances through which the grindstone slides over various points within the utilization region of the abrasive cloth.

A transfer system 1 comprising: a conveying/positioning device 3 configured to convey and position a flat sheet-shaped mold MA in a predetermined direction, on which a fine transfer pattern M1 is formed; a transfer device 5 configured to transfer the fine transfer pattern M1 to a molding target W, the transfer device 5 being provided on an upstream side in the conveying direction of the sheet-shaped mold MA; and a peeling device 7 configured to peel off the sheet-shaped mold MA and the molding target from those mutually clinging to each other, after the transfer by the transfer device 5 is performed and the conveyance by the conveying/positioning device 3 is performed, the peeling device 7 being provided on a downstream side in the conveying direction of the sheet-shaped mold MA.
摘要:
A demolding device detaches a sheet-shaped mold from a molded product. The demolding device includes a molded product holder placed in a location different from a transfer device. The molded product holder is constructed and arranged to hold the molded product while being adhered to a first region of the mold. A detaching roller on which the mold is wound is movably provided above the molded product holder in an extending direction of the mold to roll up and detach the mold from the molded product.

摘要:
A conveying/positioning device includes: a unused-mold placing device 9 that places a rolled mold MB of a sheet-shaped mold M thereon; a mold rolling-up device 11 that rolls up the flat sheet-shaped mold MA supplied from the unused-mold placing device 9; and a tension maintaining device that constantly maintains a tension of the flat sheet-shaped mold even if a form of the flat sheet-shaped mold is changed when the peeling is performed.
摘要:
A semiconductor light emitting element including, in a light extraction layer thereof, a photonic crystal periodic structure including two systems (structures) with different refractive indices. An interface between the two systems (structures) satisfies Bragg scattering conditions, and the photonic crystal periodic structure has a photonic band gap.

A transfer device 5 transfers a fine transfer pattern M1 formed on a mold M to a molding target W. The transfer device includes: a base member 47 including a press body 31; a moving member 49 including a molding target placing body 33 that sandwiches and presses the mold M and the molding target W in cooperation with the press body 31, and is provided on the base member 47 so that the molding target placing body 33 can move; and a moving body supporting body 51 that includes a guide portion 71, and is engaged with and provided integrally on the base member 47 only in a region of the base member 47 elastically deformed very slightly by reaction force when the press is performed, the region being a region where a flexure angle becomes substantially “0”.
摘要:
A demolding device (7) transfers a fine transfer pattern formed on a sheet-shaped mold to a molded product, and then detaches the sheet-shaped mold, which adheres to the molded product, from the molded product. The demolding device (7) includes a molded product holder (19) placed in a location away from a transfer device (5) and configured to hold a molded product (W) out of a mold (MA) and the molded product (W) adhering to each other, and a detaching roller unit (23) on which the mold (MA) adhering to the molded product (W) held by the molded product holder (19) is wound, and which is configured to move relative to the molded product holder (19) and thereby to detach the mold (MA) from the molded product (W).
