An assembly apparatus includes backup jigs, a press-fitting and caulking part, and an expansion part. The backup jigs is configured to back up arms of a yoke of the cross shaft universal joint from inside in an axial direction. The press-fitting and caulking part is configured to press-fit cup bearings from outside in the axial direction between bearing holes of the arms and a shaft portion of a cross shaft, and configured to caulk the cup bearings. The expansion part is configured to push a wedge body between the backup jigs and to expand the arms outward via the backup jigs. The press-fitting and caulking part is configured to press-fit the cup bearings and to caulk the cup bearings in a state in which the arms are expanded. The expansion part is configured to release an expansion of the arms after the press-fitting and caulking of the cup bearings.

An anchor device for a floor, the anchor device comprising an article securing arrangement to which an article can be secured. The article has a moveable securing mechanism. The article securing arrangement defines a cavity to receive the moveable securing mechanism, and the article securing arrangement includes a co-operating means to co-operate with the moveable securing mechanism in the cavity and secure the article to the anchor device. The anchor device has a height which is no more than 30 mm.

A method is used to forge an outer joint member of a constant velocity universal joint. Track grooves of the outer and inner joint members each have an arc-shaped ball raceway center line having a curvature center that is not offset in an axial direction with respect to a joint center. The forging method includes performing ironing by press-fitting a cylindrical portion of one end of a shaft portion of a pre-processing material of the outer joint member including the shaft portion and the cylindrical portion into a die hole of a die while a punch set that is radially expandable and contractable is fitted to an inner peripheral surface of the cylindrical portion. The punch set includes punches and a punch base to guide the punches to enable advancing and retreating. Each of the punches has a pair of forming surfaces for forming the adjacent track grooves.

A compressor comprises a housing; a motor and a cylinder in the housing; a crankshaft for transmitting rotation force of the motor to pistons of the cylinder for compressing refrigerant; a compressing space formed by an upper cylinder cover, a lower cylinder and the cylinder and the upper cylinder cover and the lower cylinder cover are also used to prop up the crankshaft. The upper cylinder cover is disposed between the motor and the cylinder. The upper cylinder cover includes an through-hole for holding the crankshaft. The upper cylinder cover includes a first side facing the motor and a second side facing the cylinder. An inner wall of the casing is laser welded with an outer periphery of the first side and/or an outer periphery of the second side of the upper cylinder cover.

A cam lock fitting having a rotating female portion which may include a safety lock which prevents separation of the male and the female portions of the fitting to prevent inadvertent pressurized discharges. Rotation of the female portion is accomplished by placing a connecting collar on the rear of the female end portion so that the female portion rotates about the connecting collar. The safety lock mechanism operates by placing opposing notches in the end of the male portion so that when the cam levers are opened the male and female portions of the cam lock fitting initially only slightly separate allowing the operator to quickly reclose the cam lock fitting if it contains pressurized material. The rotating female portion easily aligns the cam lobes of the cam lever with the notches on the male coupling so that the male and female portions can be separated.

A tolerance ring has a hollow band with outwardly extending corrugated protrusions forming waves that engage an inner surface of a bore of a housing. At one end of the tolerance ring is an inwardly flared guide surface extending axially and radially from the band. The guide surface acts as a tapered entrance to assist the insertion of a shaft into the hollow band during assembly of the ring into the bore of the housing.

A method of assembling a fastener structure on a plate body is introduced. The fastener structure includes a body portion and a fastening body. The body portion has a solderable layer, and the solderable layer is soldered to a plate body. The fastening body combines movably with the body portion. The fastening body has a head and a fastening portion. The body portion or the fastening body is provided on the plate body for soldering after it is picked up by a tool so that the body portion can combine with the plate body. Also, the body portion or the fastening body combines with an assisting pickup unit, and the fastener structure is provided on the plate body for soldering after it is picked up by a tool through the assisting pickup unit so that the body portion can combine with the plate body.

A tubular construction element and a method for forming a tubular construction element built of longitudinally extending segments in which the segments are joined together in a side-by-side relationship and in which the longitudinal direction of the tubular construction element being greater than the diameter thereof.

A method for forming a tubular construction element built up of longitudinally extending segments joined together in a side-by-side relationship, wherein the length in the longitudinal direction of the tubular construction element is greater than the diameter thereof.

A tooling assembly, including a cermet tooling body and a plastic support structure operationally connected to the cermet tooling body. The plastic support structure at least partially encapsulates the cermet tooling body. The plastic support structure includes a plastic matrix portion and a plurality of high magnetic permeability metallic particles distributed throughout the plastic matrix portion. Each respective high magnetic permeability metallic particle has a magnetic permeability of at least 0.0001 H/m and each respective high magnetic permeability metallic particle has a relative magnetic permeability of about 8000. The plastic matrix portion is selected from the group consisting of high molecular mass polymers, thermoplastics, thermosetting polymers, amorphous plastics, crystalline plastics, resin-based materials, and combinations thereof.
