Provided is a joint component manufacturing method for reducing occurrence of burrs upon bonding between a first member having a hole and a second member having a shaft portion and firmly bonding both members. In the method for manufacturing a joint component 100, a hole-side weak press-fit portion 112 is formed at a hole 111 of a flat plate ring-shaped first member 110. Moreover, each of a shaft-side weak press-fit portion 122 and a shaft-side strong press-fit portion 124 is formed at a shaft portion 121 of a cylindrical second member 120. The hole-side weak press-fit portion 112 and the shaft-side weak press-fit portion 122 are defined by a first weak press-fit interference Lw1 formed thinner than a first strong press-fit interference Ls1. The shaft-side strong press-fit portion 124 is defined by a first strong press-fit interference Ls1 as the minimum necessary press-fit interference for electric resistance welding upon electric resistance welding between the hole 111 and the shaft portion 121.

A technique facilitates the insertion and/or extraction of an electronics cartridge with respect to a corresponding cartridge housing which may be used in a downhole tool, such as a logging tool. An insertion tool comprises a frame to which the cartridge housing may be coupled to enable insertion of a corresponding electronics cartridge. The insertion tool comprises a cartridge adapter which may be selectively engaged with the electronics cartridge. Additionally, the insertion tool comprises a cable system which may be mounted on the frame and coupled with the cartridge adapter. When a cable of the cable system is pulled by, for example, a cable winch, the cartridge adapter is moved in a direction which forces the insertion of the electronics cartridge into the corresponding cartridge housing. In some embodiments, the cable may be rerouted in the cable system to enable extraction of the electronics cartridge from the cartridge housing.

Further, the diameter of the support shaft in the positioning regions may be smaller than the diameter of the passage opening in the fastening sections, and the diameter of the support shaft in the fastening regions may be smaller than the diameter of the passage opening in the positioning sections.

An off-shore port system includes a land-based port infrastructure area, an off-shore cargo ship docking area located in a body of water, and a transportation system having at least one tube connecting the land-based port infrastructure area and the off-shore cargo ship docking area.

A method for joining components of a vehicle drive axle assembly. The method includes heating an axle housing to a first predetermined temperature and cooling a pinion cartridge to be installed with the housing to a second predetermined temperature. Removing the axle housing from exposure to the first predetermined temperature and removing the pinion cartridge from the second predetermined temperature and rapidly installing the pinion cartridge within the axle assembly before the axle assembly and the pinion return to ambient temperature provides a frictional fit, joining the two components without use of additional fastening devices.

A method for manufacturing a rifle barrel is provided. The method is attained by providing an inner barrel defining a rifle bore, and having an outside diameter of a selected first amount at room temperature. Further, by providing an outer sleeve defining a bore, and having a second diameter at room temperature less than the first amount. The outer sleeve is heated to a temperature above room temperature, and the inner barrel is inserted into the bore of the sleeve.
