Abstract: A surface fastener and a product attached with the same surface fastener, having a structure for reducing a sound generated upon separation of a surface fastener member itself and capable of reducing a sound generated upon separation of the product attached with the same surface fastener. A sheet material is attached to a rear surface of a flat base material of a surface fastener member comprising an engaging-element-formation region having multiple engaging elements on a front surface of the flat base material and an engaging-element non-formation region having no engaging elements or comprising a sewing region and a non-sewing region. The sheet material has apparent density of 0.5 g/cm3 or less at least in a region corresponding to the engaging-element-formation region or the non-sewing region as sound transmission restricting means, or has at least one through hole as the sound transmission restricting means. Further, the apparent density of the flat base material is set to 0.5 g/cm3.

Abstract: A mold shim or insert is disclosed, which is placed between the surface of a forming mold or mold magnet and a fastener strip that is to be molded into a foam object. The mold shim compensates for the variability of the mold surface and provides a more even surface for the fastener strip to seal against —thereby preventing fouling of the strip's fastening elements during the molding process. Alternative embodiments of the invention are not used with a fastener strip, but instead have engaging members on their non-mold-proximate surface for engaging clips or wires which are thereby embedded into the foam object during the molding process.

Abstract: Machining portions such as a cutter portion, a slider inserting portion and an upper stopper attaching portion are provided around the vertical axis of a fixed table portion in order of machining. A fastener chain cut to have a predetermined length is held by the fixed table portion and a gripper of a rotator provided around the same vertical axis. The fastener chain is rotated and transferred to each of the machining portions based on the intermittent rotation and control of the rotator in the holding state in the gripper. Every time a predetermined machining is completed in each of the machining portions for the fastener chain rotated and transferred intermittently, it is possible to rotate and transfer the fastener chain simultaneously and intermittently to the next machining portion, thereby carrying out the necessary machining continuously.

Abstract: A concealed type slide fastener comprises two fastener tapes having their opposed edges folded thereon; two rows of fastener elements mounted on the folded edges; a top end stop mounted a fastener element row; and a slider movable along the element rows. The slider 1 has a slider body and a guidepost mounted on the body to define therewith a guide channel through which the element rows run. The guidepost has a sliding surface formed on each side and an overhanging element-guiding portion extending from the upper end of the sliding surface. The concealed type slide fastener further includes means for preventing contact between the element-guiding portion and a corner of the top end stop which faces the element-guiding portion.

Abstract: A rotary valve which can securely shut off a fluid flow without improving a working accuracy of an outer peripheral surface of a valve and an inner diameter portion of a body, and which has a simple and compact structure, wherein a gap is formed between the outer peripheral surface of the valve and the inner diameter portion of the body, a lip portion of seal means attached within a second lead air flow path is brought into contact with the outer peripheral surface of the valve on the basis of an elastic force of a support portion, and the lip portion securely seals between the second lead air flow path and the gap.

Abstract: The cord stopper (1) comprises a plug (10), and a socket (20) into which the plug (10) is inserted. The plug (10) comprises a plug body (11) having a first string passage hole (111) and one or more elastic leg pieces (12). The socket (20) has a second string passage hole (23) capable of being in communication with the first string passage hole (111) and a third string passage hole (24). The elastic leg pieces (12) hold the string inserted and passed through the third string passage hole (24) by themselves, or together with an inner surface of the socket (20). With this configuration, when the cord stopper (1) is fixed on the string (3), it is not necessary to form an edge section of the string into a loop form, and therefore can easily be fixed. Further as the string (3) is held with the elastic leg pieces (12), the holding state can easily be released, and the cord stopper (1) can easily be replaced with another one.

Abstract: Coil-like or zigzag-like linear fastener elements formed of synthetic fiber mono-filaments are attached such that coupling heads project from a side edge of a fastener tape and at least one coupling head thereof located at a top end is moved to the inside of the fastener tape so as to substantially coincide with the side edge. Then, the fastener element is fused to the fastener tape in a state in which an inverted portion project inwardly while the coupling heads are in a non-coupling condition, so as to form a top end stop. The top end stop formed of the linear fastener element includes plasticity and provides an excellent tactile feeling without any burr on the surface thereof.

Abstract: In an insulator (21) inserted between a carburetor (30) and a cylinder (3) for a purpose of insulating heat, there are formed an intake passage (22) connected to the carburetor (30), and a pair of first air passages (23) connected to respective air flow paths (14) communicated with a pair of scavenging ports (10) formed in the cylinder (3). Air control valves (25) are respectively provided within a pair of first protruding portions (33) communicating with an air cleaner (32), and are connected to the pair of first air passages (23) via a pair of connection members (35). Portions from the air passages within the pair of first protruding portions (33) to the pair of first air passages (23) are respectively formed as smooth air passages in which a change of an inner diameter cross sectional area in a connection portion is small.

The button body (1) is turnably fixed to the fabric (6) by the attachment. The extending portion (4) has an insert portion (54) adapted to be inserted into a buttonhole, a guide (55) extending arcuately from the insert portion (54) toward the button body (1), the guide (55) guiding the button body (1) to the buttonhole when the button body (1) is turned.

Abstract: A weld portion produced by heat welding and a non-weld portion which does not undergo heat welding are formed on a contact face between an inside face of a stopper portion made of synthetic resin and a surface of a fastener tape. Preferably, a bottom end face of a rear side of the stopper portion is made substantially flush with a rear surface of the fastener tape by heating with pressure. Consequently, embrittlement of the stopper portion is prevented and its fixing strength is secured, thereby eliminating itchy feeling and feeling of discomfort originating from a configuration of the upper stopper portion.
