Title: Method of shaping a flex mask for use in uniform optical coating by ion beam sputtering
Inventor: LAM LEO
IPC: C23C14/04
Filed: 2001-05-22
Abstract: A method of generating a mask for use in an ion beam sputtering system for coating oxides on a plurality of mirrors located on a rotating platen. The mask reduces non-uniformity of the oxide coating the mirrors in a radial direction from the platen axis of rotation. The shape of the mask is derived from a test run of the coating thickness on a stationary glass plate having the same area as the platen. The resulting coating thickness on the glass plate is measured by an ellipsometer as a function of position. The measured coating thickness is mapped to produce a corresponding flux pattern. A coating rate map is then determined by dividing coating thickness by coating time. The functional form of the mask is determined in width along a radial distance of the platen. The coating rate for a predetermined radial distance is obtained by adjusting angular width of the mask, which blocks a portion of the flux radially and angularly, until the desired average coating rate is obtained for that radial distance. After all the radial distances or bands have been assigned their desired angular widths, the function form of the mask is determined.

IPC: F22B21/34
Filed: 1999-12-06
Abstract: The invention rotates to a fossil fuel fired continu-ous-flow steam generator (2) with a gas turbine combustion chamber (4) for fossil combustibles (B). On the heating gas side a vertical gas extractor (8) is mounted downstream of the horizontal gas extractor (6). The walls (9) surrounding the combustion chamber (4) are composed of evaporator tubes (10) which are welded together and vertically arranged.

During operation of the continuous-flow steam generator the tempera-ture differences between adjacent evaporator tubes (10) of the combustion chamber (4) shall be kept as low as possible. To this end, the continuous-flow steam generator (2) is provided with a number of burners (30) which are arranged in the com-bustion chamber (4) at the level of the horizontal gas extractor (6). Also, for a number of evaporator tubes (10) which can be simultaneously impinged by the flow medium (S) the quotient from the steam generating capacity M (indicated in kg/s) at full load and from the sum A (indicated in m2) of the inner cross-sectional surfaces of said evaporator tubes (10) impinged simultaneously by the flow medium (S) is less than 1350 (unit kg/sm2).
Patent CA-2360171-A1 (CA)
Title: Micro-porous filter
Inventor: KENYON LEWIS W
IPC: B01D19/00
Filed: 2001-10-24
Abstract: A micro porous gas breather/filter assembly can be coupled to a housing of an electrical enclosure. The filter assembly has a two portion housing with the filter disposed between them. An adhesive on the filter attaches the filter to one or both portions of the housing. The filter allows gas to pass from the enclosure through the filter and to the atmosphere, but prohibits liquid from passing into the enclosure device. By filtering gases and liquids in this manner, the filter vents explosive and/or flammable gases from an electrical enclosure, while preventing liquid and other contaminants from entering the enclosure and damaging the electrical device or its wiring.

Title: Cooling air supply apparatus of refrigerator
Inventor: KANG BYUNG GYU
IPC: F25D23/02
Filed: 2002-01-04
Abstract: A cooling air supply apparatus includes: a blowing fan attached at a rear wall face of a freezing chamber and forcefully circulating air cooled while passing an evaporator of a freezing cycle; a supply passage formed at a barrier partitioning the freezing chamber and a cooling chamber and supplying cooling air ventilated from the blowing fan to the cooling chamber; a rear guide passage branched from the cooling air passage and guiding cooling air backwardly of the cooling chamber; a right guide passage branched from the cooling air supply passage and guiding cooling air rightwardly of the cooling chamber; and a left guide passage branched from the cooling air supply passage, having the same diameter as that of the right guide passage and guiding cooling air leftwardly of the cooling chamber. Since a half of cooling air is guided from the supply passage to the rear guide passage and one-fourth of cooling air is respectively supplied to the right guide passage and the left guide passage, the cooling air distribution in the whole cooling chamber can be uniform. In addition, when a load occurs partially as food, or the like, is received into the freezing chamber, cooling air is concentratively discharged to the portion where the load occurs, so that a cooling operation can be quickly performed.

Title: Workload management in a computing environment
Inventor: KUBALA JEFFREY
IPC: G06F9/46
Filed: 2000-09-28
Abstract: The allocation of shareable resources of a computing en-vironment is dynamically adjusted to balance the workload of that envi-ronment. Workload is managed across two or more partitions of a plu-rality of partitions of the computing environment, which are preferably configured as groups of partitions. At least one group of the computing environment includes a plurality of partitions of the computing environ-ment. Shareable resources are assigned to the partitions of the group and are managed as a group. The managing includes dynamically adjusting allocation of a shareable resource of at least one partition of the two or more partitions in order to balance workload goals of the two or more par-titions. One example of this is managing central processing unit (CPU) resources within a computing environment. When the allocation of CPU resources to a partition of the computing environment is to be adjusted, the allocation is adjusted dynamically. The adjusting includes modifying processor weights associated with the partitions.
