Abstract:
According to the invention, the carrier gas that accelerates the spray particles during cold gas spraying, or a component of the carrier gas, is captured, cleaned and collected after the cold gas spraying process. The cold gas spray gun (3) and the work piece (5) are located in a closed tank (4) from which the used carrier gas is removed, and advantageously the helium is recovered in a helium recovery unit (9). The invention enables use of optimally acting carrier gases, such as, for example, helium or helium-containing mixtures.
Abstract:
A method for coating an ion-exchange membrane with a catalyst layer by first heating a surface of the membrane to thereby soften the surface, followed by deposition of a catalyst composition and compaction into the ion-exchange membrane to produce a catalyst-coated membrane. Heating of the ion-exchange membrane may be at a temperature between 20null C. and 50null C., typically between 30null C. and 40null C., above the glass transition temperature of the dry ion-exchange membrane. In one embodiment, the catalyst composition is fluidized in a fluidized bed reactor prior to being deposited on the membrane surface. A system for coating the ion-exchange membrane is also provided. The catalyst-coated membrane is particularly useful in electrochemical fuel cells.

Abstract:
In a method and apparatus for jetting a liquid from a nozzle of a droplet jet head and applying it to a substrate, a jet amount of the liquid to any one of at least two divided regions of a coating region of the substrate is controlled to be greater than a jet amount to the other divided regions. A spin coater can be used to rotate the substrate. To divide the coating region of the substrate, the substrate can be divided into at least an inside circumferential region and an outside circumferential region positioned at predetermined distances from the center of rotation of the substrate. In this case, the jet amount to the outside region is greater than the jet amount to the inside region.
Abstract:
The invention relates to a method for producing a tool, and a tool which can be used to create optically active surface structures in the sub-nullm range. Said tool comprises a support surface to which surface structures are applied by depositing material, said surface structures being raised in relation to the support surface. The invention is characterised in that the support surface is in-directly bonded with a mask (2) in which openings (3) having diameters in the sub-nullm range are provided or can be placed; the support surface and the mask are subjected to a coating process during which coating material is deposited onto the support surface via the openings (3) in the mask; the mask is removed from the support surface when a partial amount of the average height of the end structure pertaining to the surface structures is obtained; and the coating process is continued without a mask and with similar or different coating material.

Abstract:
A method for manufacturing structure on a printed circuit board substrate according to the invention includes positioning a printed circuit board substrate in a machine capable of performing piezoelectric deposition of a fluid manufacturing material. The printed circuit board substrate is aligned with a piezoelectric deposition head of the machine. Computer numeric control of the relative motion of the printed circuit board substrate and the piezoelectric deposition head allows droplets of the fluid manufacturing material to be deposited at selected locations of the printed circuit board substrate. The printed circuit board substrate includes a conductive surface layer and a masking structure that exposes selected portions of the surface layer, thereby forming traces upon removal of selected portions of the surface layer. Further, the structure manufactured on the printed circuit board may be a resistor.

Abstract:
Information from fan filter units and differential pressure gauges provided in a ceiling of a clean room is used to control directions and volumes of air flows blown from respective fan filter units. In order to improve a wind velocity distribution in the clean room, pressure in a ceiling chamber is made uniform and control of the FFU revolution speeds of fan filter units is made easy. In order to control directions of air flows in the clean room, damper adjusting mechanisms are provided under a grating floor of the clean room. Such arrangement enables optimizing an operating condition of the clean room and achieving energy saving.
Abstract:
The present invention is to make a towel material for forming a wet towel, that is made by a drying, compressing or evacuating manner. The towel material may form a compact unit having a strip shape, block shape, or particle shape. The towel material unit is stored in the manufacturing apparatus. After the user emits the using signal, the towel material unit falls according to the signal of the manufacturing amount, and is wet or immersed, so that the towel material unit is expanded into a wet towel.
