A corrosion resistant coated fuel cell plate and method of making the same are embodied in a metal plate provided with a graphite emulsion coating and then a layer of graphite foil which is pressed over the coating. The graphite emulsion bonds the graphite foil to the metal plate and seals fine scale porosities in the graphite foil. Flow fields are formed by stamping the coated fuel cell plate.

A holding device and method is provided for efficiently applying a coating on the exterior surface of a tubular hollow body, while preventing coating application on the interior surface and coating defects. The holding device of the present invention comprises at least two structures contacting the inner surface of the tubular hollow body and extending to a portion where the structures are connected and rotary motion is induced to rotate the tubular hollow body. The structures are arranged and shaped so that an inner hollow section is formed in which excess coating material can accumulate.

A powder coating composition includes an acid-functional polyester resin and a matting agent selected from styrene-maleic anhydride copolymers and acid-functional acrylic resins. The compositions provide low gloss finishes at low curing temperatures, as well as consistent gloss over a wide range of curing temperatures.

A fastener apparatus includes a frusto-hemispherical head portion having a flat top surface, a curved outer surface, a base portion, and a peripheral edge, with the flat top surface bearing a tool fitting. A downwardly-depending lip portion extends from the head peripheral edge and defines an annular recess in the base, the annular recess having a flat upper surface. The lip has a curved outer edge, a curved lower edge, and an inner edge having a curved lower portion and a vertical upper portion terminating in the annular recess flat upper surface. A shank portion is connected to the base and bears screw threads and a tip. An annular gasket portion is carried on the shank, and has a first uncompressed position contained radially within the annular recess, and a second compressed position extending radially beyond the lip outer edge. As the fastener is installed in a workpiece, the gasket expands to contact the lip inner edge and extend beneath the curved lower edge to form a seal between the fastener head and the workpiece. The fastener may include locking teeth terminating in the head base, adapted to resist loosening of the fastener from the workpiece. The curved outer surface of the fastener may include asymmetric ridges adapted to mechanically engage moving snow or ice to resist loosening of the fastener from the workpiece. The fastener head preferably has a width to height ratio of between 3:1 to 5:1.

A cushioned foot pad configured to adhere to the bottom surface of an individual's foot without the use of straps, ties, or other securing devices the might otherwise engage with the toes and toenails of the individual during use. The cushioned foot pad may be configured to accommodate a variety of different foot shapes and sizes in a unitary design through the use of detachable pad portions. The cushioned foot pad is relatively inexpensive to manufacture and may be stored in bulk without consuming undo space.

The invention provides an arc coating apparatus having a steering magnetic field source comprising steering conductors disposed along the short sides of a rectangular target behind the target, and a magnetic focusing system disposed along the long sides of the target in front of the target which confines the flow of plasma between magnetic fields generated on opposite long sides of the target. The plasma focusing system can be used to deflect the plasma flow off of the working axis of the cathode. Each steering conductor can be controlled independently. In a further embodiment, electrically independent steering conductors are disposed along opposite long sides of the cathode plate, and by selectively varying a current through one conductor, the path of the arc spot shifts to widen an erosion corridor. The invention also provides a plurality of internal anodes, and optionally a surrounding anode for deflecting the plasma flow and preserving a high ionization level of the plasma. The invention also provides a shield at floating potential, restricting the cathode spot from migrating into selected regions of the target evaporation surface outside of the desired erosion zone. The shield may be positioned immediately above the region of the target surface in the vicinity of the anode, protecting the anode from deposition of cathodic evaporate and providing better distribution of cathodic evaporate over the substrates to be coated. The invention further provides correcting magnets adjacent to the short sides of the target, to move the arc spot between the long sides.

The present invention relates to an oscillating shielded cylindrical target assembly comprising a cylindrical target, a motor assembly adapted to oscillate the cylindrical target, a shield, and a magnet assembly. Embodiments of the present invention also include a cylindrical target that has an outer surface containing a plurality of divided sections; the sections being disposed lengthwise around the target to form strips running lengthwise across the target. Each section includes a single sputtering material, such as silver, titanium, or niobium, that is intended to be applied as a separate coating on a substrate, such as glass.

Concave grooves for forming a receiving layer for inkjet printing are provided at the inner peripheral and outer peripheral boundary portions of an application region on a disk substrate. The concave grooves are formed with a substantially V-shaped cross section, and with a depth d that is at least equal to the film thickness of the coating film within a central region between the concave grooves. A plurality of nozzles of a supply device is arrayed in a radial direction across the central region between the concave grooves, and a substantially constant quantity of coating liquid per unit of surface area is applied so as to form a coating film of a predetermined thickness. The applied coating liquid portions are flattened by a mutual leveling effect. During drying, the coating film inside the concave grooves does not dry first, but rather dries and contracts at substantially the same time as the coating film within the central region, meaning a receiving layer of uniform film thickness can be formed over the entire central region.

An electrostatic coating system includes a coating robot (1) and an electrostatic atomizer (6) attached to a polyarticular wrist portion (5) of the robot (1). The atomizer (6) includes an end plate (45), metallic connector (50) fixed to the end plate (45) in electric conduction, high voltage generator (20) and bell head (18). Electric power is supplied to the high voltage generator (20) through the connector (50). Wires (53) are connected to the connector (50) to take out high voltage leak caused by contamination like a deposition of paint on outer surfaces of the atomizer (6) through the wires 53 to control the high voltage generator (20) to lower the value of the high voltage applied to the bell head (18) of high voltage leak detected through the wires (53) is larger than a predetermined threshold value.

A chamber has a wall surface fitted with a liner. The liner is removably provided to the chamber with no fixed relation therebetween. By simply opening a light source to remove a heat diffusion plate, a hot plate and a tubular member from the chamber, the liner can be easily detached accordingly from the chamber. When a semiconductor wafer cracks to litter the chamber with its fragments, the chamber can be easily cleaned by simply detaching the liner. The liner has an outer surface subjected to surface roughening by honing. When a flash lamp emits flashlight of considerably high intensity, the roughened outer surface of the liner serves to block this flashlight. As a result, the metal surface inside the chamber is prevented from being exposed to the flashlight emitted from the flash lamp.

A gas wiping apparatus for use in coating a molten metal onto a steel strip. In the apparatus, a chamber, to which a high pressure gas is supplied, defines a multistage uniform pressure space. A lip support unit is associated with a front of the chamber to allow the high pressure gas to flow therethrough, the lip support unit supporting the apparatus against load. Upper and lower lips are associated with a front of the lip support unit to cooperatively define an outlet. The upper lip adjusts a gap of a gas outlet cooperatively with the lower lip, and can be easily installed in a lip support unit while adjusting the gap of the gas outlet stably. Also, edge over coating (EOC) of the steel strip can be prevented without an additional auxiliary nozzle.
