Abstract: The purpose of the present invention is to provide a culture container capable of preventing a concave meniscus without using a jig. In order to achieve this purpose, the present invention provides a culture container (1A) provided with: a base (3) having a concave portion (4); and a water-repellent layer (5) formed on an outer edge region (411) of the bottom (41) of the concave portion (4) and the inner circumferential surface (42) of the concave portion (4). One of the surfaces of the water-repellent layer (5) is exposed to the space in the concave portion (4).

Abstract: [Task] It is to provide a fiber-reinforced resin structure having improved surface properties and reinforced with carbon fibers or glass fibers while keeping lightweight properties. [Solution] A fiber-reinforced resin structure is constructed by forming a thermal sprayed coating composed mainly of boron carbide on a fiber-reinforced plastic substrate as a top coating.

Abstract: There is provided a substrate processing apparatus, comprising: a processing chamber in which a plurality of substrates are housed, the substrate having thereon a lamination film composed of any one of copper-indium, copper-gallium, or copper-indium-gallium; a reaction tube formed so as to constitute the processing chamber; a gas supply tube configured to introduce elemental selenium-containing gas or elemental sulfur-containing gas to the processing chamber; an exhaust tube configured to exhaust an atmosphere in the processing chamber; and a heating section provided so as to surround the reaction tube, wherein a porous coating film having a void rate of 5% to 15% mainly composed of a mixture of chromium oxide (CrxOy:x, y are arbitrary integer of 1 or more) silica is formed on a surface exposed to at least the elemental selenium-containing gas or the elemental sulfur-containing gas, out of the surface of the reaction tube on the processing chamber side.

Abstract: It is to propose an internal member for a plasma treating vessel having excellent resistances to chemical corrosion and plasma erosion under an environment containing a halogen gas and an advantageous method of producing the same, which is a member formed by covering a surface of a substrate with a multilayer composite layer consisting of a metal coating formed as an undercoat, Al2O3 film formed on the undercoat as a middle layer and Y2O3 sprayed coating formed on the middle layer as a top coat.

Abstract: A fiber reinforced plastic reflector has a sandwich construction and comprises a core, two fiber reinforced plastic plates which are secured to opposite sides of the core, and a reflecting film which is formed on the outer surface of one of the fiber reinforced plastic plates. The core is made from an isotropic material having a low density and a low linear expansion coefficient. In one form of the invention, the core is a plate of a material selected from a uniform foamed metal having a density of 0.1-1.0 g/cm.sup.3 ; uniform, porous glass having a density of 0.05-1.0 g/cm.sup.3 ; and a uniform, porous ceramic having a density of 0.3-1.0 g/cm.sup.3. In another form of the invention, the core is a corrugated sheet and a flat sheet which is secured to at least one side of the corrugated sheet, the corrugated sheet and said flat sheet being made of a material selected from a uniform Kevlar fiber reinforced plastic having a density of 0.03-1.0 g/cm.sup.3, a uniform ceramic having a density of 0.03-1.0 g/cm.sup.
