An electronic device includes an inlet including a ground terminal having a first surface and a second surface opposite from the first surface, a first casing metal plate configured to hold the inlet and contacting the first surface of the ground terminal, and a second casing metal plate contacting the second surface of the ground terminal.

A manufacturing apparatus of a ring-shaped band saw blade for manufacturing the ring-shaped band saw blade including a tooth tip to which a hard cutting tip is joined. The manufacturing apparatus includes a rotatory moving section that provides rotatory movement of the ring-shaped band saw blade including a body part having a band shape and a tooth part including a plurality of teeth formed on one side part of the body part; a surface polishing section that polishes an inner surface and an outer surface of the body part in the ring-shaped band saw blade in the rotatory movement provided by the rotatory moving section; and an end face polishing section that polishes an end face of the body part on a side opposite to the tooth part in the ring-shaped band saw blade in the rotatory movement provided by the rotatory moving section.

A method for manufacturing a pot-shaped pressure vessel, in particular an air spring pot for a vehicle, comprises the following steps: providing a pot, which comprises a bottom, which comprises at least one aperture, providing at least one screw, which comprises a head and a shank, inserting the shank of the at least one screw through the aperture from an inside of the pot, so that the shank of the screw protrudes from an outside of the bottom, and firmly joining the screw to the bottom of the pot. In the transitional area from the head to the shank at least one screw comprises a connecting section tapering from the head to the shank and extending all round the circumference. In inserting the shank through the aperture the connecting section is brought to bear against the edge of the aperture, and the connecting section is joined to the edge of the aperture along its bearing contact with the latter.
