A joint for a composite frame includes a first composite rod, a first shell abutting the first composite rod, a second shell abutting the first composite rod and disposed opposite the first shell relative to the first composite rod. The first and second shells are joined together such that composite rod is fixed therebetween. A method of forming joints of composite frame includes forming a composite frame by interconnecting a plurality of composite rods formed by an Automated Fiber Placement (AFP) manufacturing method around a mandrel, applying a first shell to the plurality of composite rods at a first location where composite rods are interconnected, applying a second shell at the first location opposite the first shell relative to the composite rods, and joining the first and second shells together with the composite rods at the first location disposed between the first and second shells.

A laser welding apparatus is provides that includes: a support member including a heat generation portion which has a size that is limited to correspond to a size of a welding area of a plurality of plastic components and is made from a material that absorbs a laser beam and generates heat, and which generates heat of a temperature that is equal to or greater than a melting temperature of the plastic components; a laser beam irradiation unit for converging a laser beam to be transmitted through the plurality of plastic components, and irradiating the laser beam toward the heat generation portion through the plurality of plastic components; and a welding controller for causing a laser beam to be irradiated at the heat generation portion using the laser beam irradiation unit to thereby cause the heat generation portion to generate heat, and welding abutting faces of a welding area of the plurality of plastic components with heat that is generated.

A stabilizer bushing installed on a stabilizer bar is made of two divided parts of rubber or the like to prevent or decrease generation of a gap in a bonding surface. The stabilizer bushing installed on an outer periphery of the stabilizer bar by adhesion includes divided rubber bushings of an upper rubber bushing and a lower rubber bushing. Before adhesion, both end portions of the upper and lower rubber bushings, respectively, in a circumferential direction are tapered so that an overlapping amount between the upper and lower rubber bushings increases toward the outer periphery side of the bushings. After adhesion, a bonding surface is bonded by pressure

A fiber-reinforced plastic component includes a three-dimensional component plastic member and at least one reinforcement fiber rod. The three-dimensional component plastic member determines at least parts of a shape of the plastic component. The three-dimensional component plastic member has at least one void which is open to at least one side and in which the at least one reinforcement fiber rod is placed.

A composite tube may include a body having a longitudinal centerline axis and an end portion having a tapered section and an end rim. At least one of a radially outward edge and a radially inward edge of the end rim may be non-circular. The end rim may be circumferentially continuous. The end rim may be an undulating annulus. A joint assembly may include a support wedge that at least partially engages at least one of a radially inward surface of the end portion and a radially outward surface of the end portion of the composite tube.

A coaxial connector for interconnection with a coaxial cable with a solid outer conductor by ultrasonic welding is provided with a monolithic connector body with a bore. An annular flare seat is angled radially outward from the bore toward a connector end of the connector, the annular flare seat open to the connector end of the connector. An inner conductor cap is provided for interconnection with an inner conductor of the coaxial cable by ultrasonic welding. The ultrasonic welding of each of the inner and outer conductor interconnections may be performed via inner conductor and outer conductor sonotrodes which are coaxial with one another, without requiring the cable and or connector to be removed from their fixture.

A joint structure is a joint structure between a first member having a pillared end part made of a fiber-reinforced plastic and a second member different from the first member. The end part of the first member is reversely tapered in an axial direction, while a joining member is disposed along a reversely tapered form of the end part. The second member is provided in contact with an end face of the first member and connected to the joining member. A plurality of fibers substantially extending in the axial direction of the end part of the first member are provided within the end part and disposed to form a larger angle with the axial direction of the end part of the first member as they are disposed to be closer to a surface constituting the reversely tapered form in a radial direction of the end part.

A suture and a suture retainer are positioned relative to body tissue. Ultrasonic vibratory energy is utilized to heat the suture retainer and effect a bonding of portions of the suture retainer to each other and/or to the suture. Portions of the body tissue may be pressed into linear apposition with each other and held in place by cooperation between the suture and the suture retainer. The suture retainer may include one or more portions between which the suture extends. The suture retainer may include sections which have surface areas which are bonded together. If desired, the suture may be wrapped around one of the sections of the suture retainer. The suture retainer may be formed with a recess in which the suture is received. If desired, the suture retainer may be omitted and the sections of the suture bonded to each other.

A laser welding apparatus is provides that includes: a support member including a heat generation portion which has a size that is limited to correspond to a size of a welding area of a plurality of plastic components and is made from a material that absorbs a laser beam and generates heat, and which generates heat of a temperature that is equal to or greater than a melting temperature of the plastic components; a laser beam irradiation unit for converging a laser beam to be transmitted through the plurality of plastic components, and irradiating the laser beam toward the heat generation portion through the plurality of plastic components; and a welding controller for causing a laser beam to be irradiated at the heat generation portion using the laser beam irradiation unit to thereby cause the heat generation portion to generate heat, and welding abutting faces of a welding area of the plurality of plastic components with heat that is generated.

An electrical heating bonding device 1 bonds a member M1 to be bonded, which is made of a metal, and a member M2 to be bonded, which is made of a resin. The electrical heating bonding device 1 includes: an upper electrode 11 and a lower electrode 12 which sandwich the member M1 to be bonded, and are electrically conductive with the member M1 to be bonded; a pressurizing unit 20 which applies pressure to a bonding surface between the member M1 to be bonded and the member M2 to be bonded; a temperature sensor 30 which detects a temperature of the member M1 to be bonded; and a control unit 40 which controls the pressurizing unit 20 to apply the pressure to the bonding surface, after the temperature detected by the temperature sensor 30 reaches a predetermined set temperature Ts.
