Abstract: The purpose of the present invention is to provide a rotary atomizing head that paint supplied to an inner peripheral surface is spread on the inner peripheral surface uniformly so as to improve the quality of coating and to lengthen the life of the rotary atomizing head. An inner peripheral surface 67 diametrically expanded from the center of the rotary atomizing head to a peripheral edge 61b is formed and centrifugal force generated by the rotation is applied on the paint supplied to the inner peripheral surface 67 so as to discharge the paint outside atomizingly. A step part 68 is formed at the middle portion of the inner peripheral surface 67 between paint supply holes 65d, supplying paint or solvent to the inner peripheral surface 67, and the peripheral edge 61b of the inner peripheral surface 67.

Abstract: A pair of rimless type spectacles having a flexible lens holding member such as a nylon wire for holding lenses arranged in such a manner that a decoration is fastened to the lens holding member so that the decoration is fastened to the periphery of the lens so as to freely design the spectacles. It is preferable that the position at which the decoration is fastened can be adjusted and the decoration can be changed for another one.

Abstract: Spectacles including a plurality of clamp members for connecting lens supporting parts of the spectacles to the lenses, and elements for increasing friction resistance between a lens contacting portion of a clamp member and respective surfaces of the lens.

Abstract: An eyeglass frame of the type having at least a member made from the Ni-Ti base alloy with a shape-memory effect, the member being joined with another member by soldering. The Ni-Ti base alloy member has a portion previously coated by a Ni or Ni-alloy plating of 3 to 50 micron thickness and then joined to the other member by soldering to increase the adhesive strength between the portions soldered to a desired extent.

Abstract: An eyeglass frame (10) consisting of outside and inside synthetic-resin members (20, 25), a metallic-plate core member (12) sandwiched in between the outside and inside members, the core member (12) being partly formed with a plurality of holes (16) which are filled up with colored resins (18). The outside member is composed of inner, colorless, transparent and outer, colored, opaque layers (21, 22) of which the outer layer is removed partly in the form of a window through which the colored resins (18) and the holes (16) appear as stained-glass patterns.
