Abstract: Provided are eyeglasses that can be supported so as to fit each of various head shapes of wearers without any gap, are extremely excellent in preventing slippage and falling during exercise, have a good fitting feeling, and do not particularly require an adjustment operation for preventing slippage and falling. The eyeglasses include a frame, end pieces attached to both end portions of the frame, and temples attached to the back ends of the end pieces so as to be swingable in the inward and outward directions, and a temple pad protrudes from the front end of the temple. The temple pad moves inward when the temple swings outward, and the temple pad moves outward when the temple swings inward.

Abstract: Disclosed is a burner head capable of securing heat resistance and durability characteristics and improving the quality of machining at the same time, capable of easily and stably machining a material into a complicated shape. A second metal primary material of the iron family having high workability and first metal primary materials of the SUS family having high heat resistance are rolled out. Their side plate ends are butt-welded by laser to form a one-piece metal flat-plate material. A press molding machine is operated to press mold recessed portions of a pair of plate members simultaneously with cutting along a contour line. Then, folding is carried out, and they are closely joined together. A gas passage is formed by a recessed portion of the second metal primary material section. A burner port is formed by a recessed portion of the first metal primary material section.
