The invention forms a Sn coating layer and a Cu—Sn alloy coating layer having a suitably controllable planar shape in a PCB terminal. A group of Sn coating layers being as a plurality of essentially parallel lines is formed as the surface coating layer, and a Cu—Sn alloy coating layer 2 is exposed on the outermost surface on both sides of Sn coating layers each constituting the group of Sn coating layers. The Sn coating layers have a width of 1 to 500 μm, an interval between adjacent Sn coating layers is 1 to 20000 μm, and an outermost maximum height roughness in a terminal insertion direction is at most 10 μm.

The invention provides a method for molecular analysis. In the method, sidewalls are formed extending through a structure between two structure surfaces, to define an aperture. A layer of material is deposited on the aperture sidewalls and the two structure surfaces. The aperture with the deposited material layer is then configured in a liquid solution with a gradient in a chemical potential, between the two structure surfaces defining the aperture, that is sufficient to cause molecular translocation through the aperture.

A double chamber aerosol container has a soft elastic inner sack, mounted within a metal container body, and a housing mounted to a top end of an inner periphery of the inner sack. The inner sack is in contact with special sized temporarily fitting portion as well as insertion contact portion of the housing to prevent the propellant from leaking out. Where an inner diameter of the top end of the inner periphery of the inner sack is 1, the outer diameter of an insertion contact portion of the housing is set to 1.02 to 0.98, the maximum outer diameter of the temporarily fitting portion is set to 0.97 to 0.95, the minimum outer diameter of the temporarily fitting portion is set to 0.94 to 0.88, and the minimum portion is formed below the maximum portion as well as the width in the up and down directions of the temporarily fitting portion is set to 0.19 to 0.10.

The surface roughness of a copper sheet is adjusted to have an arithmetic mean roughness Ra of 0.5 μm or more and 4.0 μm or less in a direction parallel to a sliding direction upon connection, a mean projection-depression interval RSm of 0.01 mm or more and 0.3 mm or less in the direction, a skewness Rsk of less than 0, and a protrusion peak portion height Rpk of 1 μm or less. Further, as a surface coating layer, a Sn coating layer group X observed as a plurality of parallel lines is included, and a Cu—Sn alloy coating layer is present adjacent to each side of each of Sn coating layers constituting the Sn coating layer group X. The maximum height roughness Rz is 10 μm or less in a direction of part insertion. At the time of stamping the copper sheet, the copper sheet is surface-roughened by pressing, thereby forming depressions observed as a plurality of parallel lines in the surface of the copper sheet. The copper sheet is then plated with Cu and Sn, followed by reflowing to complete the production.

A push button for powder aerosol has a push button body, a nozzle and a guide passage. The nozzle is formed in the push button body with a diameter in a range of 0.4 mm to 1.0 mm and a length in a range of 0.3 mm to 2.0 mm in communication with a stem of an aerosol container. The guide passage is formed in the push button body in continuation with an outer end of the nozzle in extending in a spraying direction of the nozzle and formed with a diameter of a range of 1.0 mm to 3.0 mm that is larger than the diameter of the nozzle and a length of a range of 3.0 mm to 20.0 mm for guiding the contents of the powder aerosol. The nozzle flows out the contents with diffusion suppressed, so that accurate application can be made to the limited range on aimed areas such as skins.

A mating-type connecting part can be obtained by stamping and surface-roughening a copper sheet into a predetermined shape with depressions as a plurality of parallel lines. The copper sheet then has a roughness of from 0.5 μm to 4.0 μm parallel to a sliding direction upon connection, a mean projection-depression interval of from 0.01 mm to 0.3 mm in that direction, a skewness less than 0, and a protrusion peak portion height of 1 μm or less. The copper sheet is then plated with Cu and Sn, followed by reflowing. The result is a connecting part having a Sn surface coating layer group as a plurality of parallel lines, and a Cu-Sn alloy coating layer adjacent to each side of each Sn surface coating layer.

A double chamber aerosol container capable of filling contents in the container has a container cap that constitutes a liquid container with an inner sack to be temporarily fitted to a bead portion of an outer container while the inner sack is placed within the outer container. When the inner sack is placed with the outer container, the lower end of the inner sack is not in contact with the bottom of the interior of the outer container. The propellant is filled in the outer container upon forming a filling gap between the container cap and the bead portion, and then the container cap is surely clinched to the bead portion of the outer container.

A double chamber aerosol container capable of filling contents in the container upon cutting off open air has an inner sack, whose volume is reducible according to reduction of contents, formed with temporarily engaging portions. A housing to which a valve assembly is arranged is inserted in the inner sack where the temporarily engaging portions are temporarily engaged with a ring-shaped neck portion of an outer container. After propellant is filled in a space between the inner sack 1 and the outer container during this temporarily engagement, the inner sack is inserted in the outer container to form the double chamber aerosol container.
