Abstract:
Herein are disclosed apparatus and methods for impinging fluids, e.g. heated fluids, onto the surface of substrates and then locally removing the impinged fluid. The apparatus may comprise at least first and second fluid delivery outlets that are in diverging relation to each other. The apparatus may comprise at least first and second fluid capture inlets that are locally positioned relative to the first and second fluid delivery outlets, respectively. The apparatus and method may be used e.g. to impinge fluids onto two converging substrates and may be used to heat the surfaces of the substrates so as to facilitate melt-bonding the substrates to each other.
Abstract:
A magnetic disc cartridge includes a casing formed of upper and lower shell halves mated together, a disc-like recording medium supported for rotation in the casing and a liner fixed to each of the inner surfaces of the upper and lower shell halves by ultrasonic welding by use of an ultrasonic welding horn. The liner has an outer contour defined by an outer peripheral edge, a central opening defined by an inner peripheral edge, and a slit-like cutaway portion defined by a pair of linear edges extending between the outer peripheral edge and the inner peripheral edge. The ultrasonic welding horn is provided with a welding pattern in the form of a protrusion pattern formed on a welding face thereof over the entire welding area in which the ultrasonic welding horn is brought into contact with the liner, and the liner is welded to the inner surface of the shell half over the entire area of the liner along the welding pattern.

Abstract:
A composite structure comprises a porous medium (15), a substrate (10) provided with at least one drainage pathway, and a support and drainage medium (13) sandwiched between the porous medium (15), and the substrate (10). The porous medium (15), the support and drainage medium (13), and the substrate (10) are bonded free of any adhesive.

Abstract:
Method and apparatus for cutting a fluorinated polymer membrane and simultaneously joining it to a polymer frame. The method comprising the steps of: (i) contacting a fluorinated polymer membrane with a polymer frame at the point where a cut and join is desired, and (ii) directing at least one laser beam onto the point of contact between the membrane and the frame so as to cut the membrane and effect a join to the frame.
Abstract:
A substrate containing silicon is coated with primer containing silane coupling agent. A hard resin product is brought into contact with the primer coated part of the substrate and the resin product is vibrated while the product is pressed to the substrate. A welding apparatus has a welding gun having a horn which holds the resin product, a holding table which is placed movably beneath the horn and holds the substrate between the horn and itself, a transfer means which transfers the welding gun and the holding table relatively to each other and a converter which generates ultrasonic vibration of the horn in accordance with inputted signals. Thus, a resin product is welded to a substrate firmly at a low cost.
