摘要:
A heat resistant alloy member that maintains the creep strength and improves the fatigue characteristics is provided. The heat resistant alloy member according to the present invention includes a recrystallized structure layer including finer grains on the surface of the member than those inside of the member. The recrystallized structure layer is formed by forming a stirred layer by giving processing strain to the surface of the member using a friction stir processing, and applying recrystallization heat treatment to the stirred layer for recrystallization.

An optometric apparatus and an optometric method which perform an accurate eye examination on people who have a wide range of refractive powers with astigmatism, myopia or hyperopia, and which are also applicable especially to those with mixed astigmatism are provided. The apparatus performs a subjective eye examination by prompting a subject to view test symbols displayed on a computer screen by one of the right and left eyes at a time. The system includes astigmatic axis angle determination means which displays test symbols for determining an astigmatic axis angle and then determines the astigmatic axis angle, hyperopia and myopia determination means which displays test symbols for determining hyperopia or myopia in two orthogonal orientations selected based on the determined astigmatic axis angle, and determines hyperopia or myopia at the astigmatic axis angle and at an angle orthogonal thereto, and refractive power determination means which displays test symbols for determining a refractive power in two orthogonal orientations selected based on the determined astigmatic axis angle and determines a refractive power at the astigmatic axis angle and at an angle orthogonal thereto.

A rimless eyeglasses lens-installing apparatus, a connector connects a lens to a lug and a fastening tool fixed the lens and the connector to each other. The fastening tool has a first fastening member and a second fastening member. A metal insertion member having a threaded hole formed thereon is disposed in an internal portion of the first fastening member by insert molding. An outer threaded portion of the first fastening member engages a threaded portion of a lens through-hole. The threaded portion of the second fastening member is screwed into the threaded hole of the insertion member. A portion of the first fastening member projecting from a rear surface of the lens is cut off appropriately.
