Abstract: The finger supporter is disclosed. The finger supporter includes: a first anchor portion 2 that is formed at an upper end 10a of a tubular fabric and causes the tubular fabric to be fastened to a forearm wrist portion of a wearer; a second anchor portion 3 that is formed to continue two points of a circling portion on the other end side of the tubular fabric and forms the circling portion into two opening portions 12a and 12b with different sizes; and a first support portion 4 that couples the second anchor portion 3 and the first anchor portion 2 and supports any one finger inserted into the smaller opening portion 12a from among five fingers.

Abstract: [Problem to be Solved] To provide a finger supporter capable of stabilizing hand joints of a wearer and reducing a load on any one finger from among five fingers. [Solution] The finger supporter includes: a first anchor portion 2 that is formed at an upper end 10a of a tubular fabric and causes the tubular fabric to be fastened to a forearm wrist portion of a wearer; a second anchor portion 3 that is formed to continue two points of a circling portion on the other end side of the tubular fabric and forms the circling portion into two opening portions 12a and 12b with different sizes; and a first support portion 4 that couples the second anchor portion 3 and the first anchor portion 2 and supports any one finger inserted into the smaller opening portion 12a from among five fingers.

Abstract: The present invention relates to a method of processing an article to be processed so as to cause the article to create rainbow color and a method of manufacturing an article made of aluminum or its alloy which presents rainbow-colored reflective luster. An aluminum plate is prepared as a substrate (2) of an article (1) to be processed. A nickel-phosphorus alloy deposit (3) is formed on the surface of this aluminum substrate (2) by an electroless plating method. Subsequently, this article is heat-treated at the temperature of 150 to 600° C. for 5 seconds to 1 hour in an air atmosphere. Subsequently, pulsed laser light (10) is irradiated onto the surface of the deposit (3). Be performing the aforementioned steps, diffraction gratings (5) which present beautiful rainbow-colored reflective luster can be assuredly formed in the surface of article (1). Furthermore, the processing speed can be further increased.

Abstract: The method and apparatus for processing metal surfaces by forming the fine irregularity patterns onto metal surfaces in accordance with both of the strong and weak patterns characterized by the interference light on the metal surfaces under the irradiation of the interference light of laser beam onto the metal surfaces is described.
