Abstract: In an electronic component feeding device which comprises a component carrier tape wound around a reel, on which electronic components are accommodated in cavities formed on a support tape whose surface is covered by a removable top tape, a reel guide is pivotally mounted, which has a U-shaped cross section that resembles a hook, an open end of the hooked part being formed at a fixed angle &thgr;, and which holds the reel when engaged with an outer peripheral edge of the reel.

Abstract: In an electronic component supply device electronic components are accommodated within cavities formed in a carrier tape of which surface is covered with a top tape. A peeling portion for peeling off the top tape from the carrier tape includes a peel-away cutout portion cut into a tape transfer direction. A thin plate has an angled portion having a rounded portion. A concavity, in which the thin plate operates, is formed in the tape pressing member downstream of the peel-away cutout portion in the tape transfer direction.

Abstract: A receiving reel 10 comprises a receiving ratchet 11 and a detachable receiving cap 12 that is set in the receiving ratchet 11 and on which a covering tape 1c is wound, and is provided with contact members 13 and 14 that are provided on the area of engagement of the receiving cap 12 and the receiving ratchet 11. The contact members make contact in the direction of rotation and prevent the receiving cap 12 from coming loose. Mutually contacting concave and convex members 15 and 16 are provided on the contact surfaces along the direction of rotation of the contact members 13 and 14 to make it simple to detach the receiving cap 12 and to prevent it from coming loose and falling off.

Abstract: In the inner portion of a spherical annular seal member (55) extending from a cylindrical inner surface (52) to an outer surface (53) formed in the shape of a partially convex spherical surface, a heat-resistant sheet member (3) having a heat-resistant coating (2) on overall surfaces of a heat-resistant sheet and a reinforcing member (9) constituted by a metal wire net (8) are compressed and intertwined with each other, and are thus arranged to be provided with structural integrality. The outer surface (53) formed in the shape of the partially convex spherical surface is constituted by an exposed surface of an outer surface layer (56) formed of the heat-resistant coating (2), and the reinforcing member (9) constituted by the metal wire net (8) formed integrally with the outer surface layer (56) is disposed in the outer surface layer (56).

Abstract: A spherical annular seal member which has a cylindrical inner surface defining a through hole in a central portion thereof, an outer surface formed in the shape of a partially convex spherical surface, and an annular end face on a large-diameter side of the outer surface, and which is used particularly in an exhaust pipe joint, comprises: a reinforcing member made from a compressed metal wire net; a heat-resistant material filling meshes of the metal wire net of the reinforcing member and compressed in such a manner as to be formed integrally with the reinforcing member in mixed form, the heat-resistant material and the reinforcing member being provided as principal components in an inner portion of the spherical annular seal member which extends from the cylindrical inner surface to the outer surface formed in the shape of the partially convex spherical surface, boron carbide, a metal boride, a metal fluoride, graphite, and aluminum phosphate being also formed integrally with the reinforcing member and the h

Abstract: The method for assigning an identification number is constructed in that in a transmission system with transmission system managing equipment being connected to at least one of a plurality of pieces of connected transmission equipment, each of all or some of the transmission equipment acquires information peculiar to adjacent devices connected thereto and holds the information as peripheral connected-state data of each piece of transmission equipment. The transmission system managing equipment collects information from all of the transmission equipment which hold the peripheral connected-state data of each piece of transmission equipment, and on the basis of the information, determines and transmits an identification number for each piece of transmission equipment. Each of the plurality of pieces of transmission equipment carries out internal setting of the identification number thereof transmitted from the transmission system managing equipment.

Abstract: In a joint apparatus for an automobile exhaust pipe, each of a pair of juxtaposed exhaust pipes and each of a pair of mutually coupled branch pipes of a bifurcated exhaust pipe are coupled to each other. The joint apparatus is provided with a spherical joint for coupling one of the pair of exhaust pipes to one of the branch pipes of the bifurcated exhaust pipe which is disposed in correspondence with the one exhaust pipe; and a flexible extensible joint for coupling another one of the pair of exhaust pipes to another one of the branch pipes which is disposed in correspondence with the another exhaust pipe.

Abstract: A spherical annular seal having a through hole in a center thereof and a partially convex spherical surface portion on an outer surface thereof, wherein a surface of the partially convex spherical surface portion is formed into a smooth surface in which a lubricating sliding layer of a lubricating composition containing 70 to 90 wt. % of boron nitride and 10 to 30 wt. % of alumina and/or silica and a reinforcing material constituted by a metal wire net covering the lubricating sliding layer and integrated with the lubricating sliding layer are integrated in mixed form.

Abstract: A thrust bearing for use with an automobile thrust-strut type suspension comprises a lower casing made of resin, an upper casing made of resin, and a bearing piece made of resin. The bearing piece is disposed rotatably within the upper and lower casings upon snap-fitting a hook portion of an annular suspended portion of the upper casing with an engaging portion of an annular protruded portion of the lower casing. The thrust bearing is so adapted that two annular inner labyrinth portions and two annular outer labyrinth portions are respectively formed at inner and outer peripheral portions of the thrust bearing to thereby prevent sufficiently dust from intruding into a sliding surface of the bearing piece.

Abstract: A thrust bearing made of synthetic resin assembled into a strut-thrust type suspension for use in four wheel cars, comprising a casing made of synthetic resin and a bearing body made of synthetic resin, the bearing body being fitted rotatably to the casing by snap-fitting a hook portion of a suspended portion with an engaging portion of a protruded portion, the suspended portion being formed integrally with an outer circumferential edge of the casing, the protruded portion being formed integrally with an outer circumferential edge of the bearing body.
