Abstract:
A reflecting mirror for solar radiation collection includes a film mirror and a frame-shaped support member adapted to support a peripheral edge of the film mirror. The film mirror has a film thickness of 0.10 to 0.30 mm, and the support member is in contact with the film mirror and has a curved face which is convexed outward in a horizontal direction with respect to an opening face of the support member, with the curved face having a radius of curvature of not less than 8 mm. The reflecting mirror for solar radiation collection has a good heat resistance, involves less warpage of a film mirror, and predominates in specular reflectivity and light-collecting characteristics.
Abstract:
A reflecting mirror for solar radiation collection includes: a film mirror for solar radiation collection having a polygonal shape and including a resin substrate, a metallic reflective layer and a surface covering layer; and a support member having a frame shape and adapted to support a peripheral edge of the film mirror.
Abstract:
A method for producing a multilayer substrate involves: a base-material pretreatment step in which a hole forming step and a metal adhesion step are performed in no particular order, the hole forming step being a step of subjecting a core base material having at least an insulating layer and a first metal layer to a hole opening process, the metal adhesion step being a step in which a predetermined metal or metal ion is made to adhere to the other surface of the insulating layer; a desmearing step of performing desmearing by plasma etching; a cleaning step of cleaning the core base material by using an acidic solution; and a plating step of applying a plating catalyst or a precursor thereof onto the insulating layer and performing plating.
