Abstract

Disclosed is an optical member (100) which comprises: a sulfur atom-containing resin base material (11); and a photochromic layer (21) that is superposed on a surface of the sulfur atom-containing resin base material (11). In order to improve adhesion between layers, the maximum point stress measured by the following procedure x is 138 N/mm2to 177 N/mm2inclusive. Procedure x: the optical member (100) is subjected to a three-point bending test that is performed at 25°C in accordance with JIS K7171, and the maximum point stress (N/mm2) is measured at the time when the test is performed under a condition that the distance between supporting points is 34 mm, the speed is 10 mm/minute, and the radius R2 of the support base is 2 mm.

Abstract

This management system serves to: select a suitable combination of a material of a product and an identification substance for adding information to the material, the combination being suitable in terms of the functionality of the identification substance and the characteristics of the product of the material; and determine and manage the combination of the material and the identification substance. The system involves: a first database that accepts designated input information relating to a material or identification substance, and that stores information on the material; and a second database that stores information on the identification substance. From these databases, a combination of an identification substance and a material in accordance with the input information is selected using selection conditions determined in advance with regard to the information on the material and the information on the identification substance.

Abstract

Formwork according to the present disclosure is for pouring fresh concrete thereinto. The formwork comprises a plurality of boards. The plurality of boards have at least one board-like shaped object in which a surface that contact the fresh concrete has formed therein a lamination mark caused by additive manufacturing. The board-like shaped object is disposed such that, during formwork removal, the board-like shaped object can be removed toward a specific direction from concrete that is formed by curing the fresh concrete. The specific direction is the direction in which the lamination mark extends and a direction perpendicular to the direction in which layers constituting the board-like shaped object are stacked.
