Abstract: A snap button can include a snap button body and a fastener connected to the snap button body with a cloth interposed between them, wherein the snap button body includes a button member including a base; and a metal eyelet attached to an inner surface of the base, the inner surface being placed to face the cloth, wherein the button member includes an engaging portion provided on an outer surface opposite to the inner surface of the base, wherein the fastener includes a fastener base and a pin to be swaged, which protrudes from an inner surface of the fastener base, the inner surface being placed to face the cloth, and wherein the eyelet includes a cylindrical portion receiving the pin, the cloth being pierced by the pin, and the pin being swaged on the inner surface of the base of the button member.

Abstract: A button fixing member made of synthetic resin, used to fix a button having a fixing opening to a cloth, the button fixing member including a plate-like base and a post protruding from the base to a front surface side of the base The post is deformed after it passes through the cloth and the fixing opening of the button when the button is fixed to the cloth. The post includes a cavity extending from an opening on a rear surface of the base to a closed end on the tip side of the post concentrically with the post, and a solid portion between the closed end of the cavity and the tip of the post. The axial length of the solid portion is set to be ? or more of the length of the part of the post from the front surface of the base to the tip of the post.

Abstract: A method for forming a multi-colored cap part of a snap button including the steps of forming a design portion of the cap part of snap button using a first group of molds, which includes a first female mold, a first male mold, and a plate-shaped middle mold, and a slide-plate mold adapted to movably assembled to the first male mold and having a plurality of mold cavities for forming the design portion; removing the slide-plate mold having the design portion molded therein from the first male mold; movably positioning the slide-plate mold into a second female mold included in a second group of molds for forming a body portion of the cap part of snap button; positioning a post for the cap part of snap button in a second male mold of the second group of molds; and forming the body portion.

Abstract: Disclosed is a wireless surround sound speaker system wherein a transmitter broadcasts a variety of FM signals that correspond to the individual speaker channels commonly found in a surround sound system. Receivers, individually equipped with signal receiving, conditioning and amplification components, are configured to receive any one of the broadcast signals in a remote location and are used to drive a conventional loudspeaker in that location. Powered by wall socket or via DC battery packs, the receivers, used in conjunction with the transmitter, provide surround sound capabilities without the need for complex and difficult wiring.
