A method for making a battery can, for example, but not limited to, for a p-type prismatic cell may include: manufacturing at least one first battery can portion and at least one second battery can portion, using a first manufacturing process; joining the at least one first battery can portion and the at least one second battery can portion, using a second manufacturing process, different from the first manufacturing process; and inspecting the battery can to verify the joining between the at least one first portion and the at least one second portion. A method for making a battery can may include: providing at least one safety vent in a battery can and/or applying an insulation coating to one or more of an internal surface, an external surface and at least one seam of the battery can.

An inner circle and outer periphery punching step is performed in which a punching process is performed on a plate material made of a metal material to form an outline on an outer periphery side and a circle space on an inner periphery side, thereby forming an intermediate plate material. In an inner periphery bending step, the intermediate plate material is subjected to a bending process of bending a portion inside of a base circle that is a circle between an inner circle end portion and an outer circle, toward one side. In an inner periphery punching step, the intermediate plate material is subjected to a punching process of punching out inner periphery radial portions that are portions radially extending from the inner circle end portion, to form inner periphery slits extending inside of the outer circle in respective radial pieces. In an outer periphery bending step, the intermediate plate material is subjected to a bending process of bending a portion outside of the base circle from the base circle toward the one side, thereby forming a spring member.

The present invention relates to an apparatus for increasing the flow rate in an engine pipe, and a processing method therefor and, more specifically, to an apparatus for increasing the flow rate in an engine pipe, the apparatus being provided in an engine pipe so as to define a circular flow of a gas by maximizing a circular flow length of the flowing gas, enabling the gas to flow circularly along an outer surface of a flow rate increasing tube body, preventing the occurrence of a vortex due to the collision of the gas flowing in the inside and the outside of the flow rate increasing tube body, and preventing the occurrence of noise and the like since the flow rate increasing tube body is firmly fixed to the pipe.

A three-dimensional auxetic structure, comprising a plurality of adjoining hollow cells, each hollow cell having cell walls and a transversal cross section of the plurality hollow cells following a two-dimensional auxetic pattern, each cell wall comprising folding lines parallel to a plane containing the auxetic pattern such that peaks and valleys are defined in the cell walls and the cell walls being foldable along the folding lines.

A method of forming an ice resistant surface includes determining, based at least in part on a desired pattern of frost formation, a vertex angle for a ridge that is to be formed on a substrate. The method also includes determining, based at least in part on the desired pattern of frost formation, a vertex height for the ridge that is to be formed on the substrate. The method further includes forming a plurality of ridges on the substrate, where each ridge in the plurality of ridges has the vertex angle and the vertex height.

The invention relates to a method for producing highly dimensionally accurate, deep-drawn half shells having a bottom region, a jacket and optionally having a flange, wherein a half shell pre-formed from a blank is formed into a finished half shell, wherein the pre-formed half shell has excess blank material on account of its geometrical shape, and the half shell being upset by way of at least one pressing operation in an upsetting tool to form the finished half shell during the forming of the pre-formed half shell into its finished shape on account of the excess blank material. The object of specifying a method and an apparatus, by way of which the process reliability can be increased during the production of a half shell, is achieved by way of the abovementioned method by virtue of the fact that the size of the upset gap is reduced during the closing of the upsetting tool to the actual wall thickness of the jacket of the pre-formed half shell. In addition, the object is achieved by way of an upsetting tool according to the invention by virtue of the fact that two side walls are provided which, together with the bottom region of the die of the second tool half, form a corresponding die, and the side walls can be displaced perpendicularly or obliquely with respect to the movement direction of the die.
