IPC: H01M8/02
Filed: 2004-04-27
Abstract: A metal separator defines a fluid passage. The fluid passage defines a reactant gas passage formed at a first, MEA-opposing surface of the metal separator, a coolant passage formed at a second, opposite surface of the metal separator, a reactant gas manifold fluidly connected to the reactant gas passage and a coolant manifold fluidly connected to the coolant passage. The metal separator includes a rib formed thereon so as to surround a portion of the metal separator where the fluid passage is formed. The rib is adapted to contact a metal separator of an adjacent fuel cell to construct a seal for a fluid passage surrounded by the rib. A plurality of seal lines where each seal line includes each rib may be provided. By virtue of the presence of the rib, a gasket provided in a fuel cell of comparison does not need to be provided.

Inventor: LAARHUIS JAN HERMAN
IPC: H04L12/803
Filed: 2004-06-09
Abstract: Throughput between nodes such as personal computer and a subnetwork such as the Internet is increased by using inverse multiplexing over multiple intersubnetwork connections such as local loop telephone lines of different users. The different nodes share the multiple intersubnetwork connections with each other, so that the efficiency of the use of the intersubnetwork connections is increased. Each of the nodes is capable of receiving and/or transmitting inverse -multiplexed data signals over the same plurality of intersubnetwork connections. Preferably, to this end, at each node, use is made of a separate connecting device which is, on the one side, locally coupled to the node and an intersubnetwork connection and is, on the other side, remotely coupled to one or more other such connecting devices. Such connecting devices are, for instance, placed in different housings, each with, for instance, a regular connection with a local computer and, for instance, a wireless transmission connection to corresponding connecting devices in neighboring housings. The interchanged data are inverse -multiplexed and transmitted via the intersubnetwork connections as inverse multiplex data.

Abstract: Abstract of the Disclosure Absorbent paper products, such as paper towels, are disclosed which have a combination of high absorbent capacity and a moderate to low rate of absorbency for hand protection. These properties can be produced, for example, using a throughdried basesheet, such as an uncreped throughdried sheet, in which at least one surface of which has been printed with a patterned moisture barrier coating and creped. The presence of the moisture barrier coating on the surface retards the absorbent rate for that side of the sheet while allowing a significant amount of liquid to pass through to the center of the sheet.

Title: Fast loss less image compression system based on neighborhood comparisons
Inventor: SUZUKI NORIHISA
IPC: H04N19/593
Filed: 2004-05-27
Abstract: A fast loss less image compression system based on neighborhood comparisons compares pixel value differences with neighboring pixels and replaces such pixel values with the minimum of the differences. A marker is attached to a block of pixels, such that all the pixels in that block are compared with neighbors of one direction. The marker indicates how of the pixels in that block are compared. Intermittent Huffman-tree construction is used such that one tree is used for several frames. Huffman coding is used to compress the resulting frame. A single Huffman-tree is constructed once every predetermined number of frames. The frequency of Huffman-tree construction can be performed according to the instantaneous availability of processor time to perform the construction. When more processing time is available, the Huffman-trees are computed more frequently. Such frequency variation can be implemented by using an input video frame buffer.

Abstract: According to aspects of the present invention, metal oxide powder, such as yttria and alumina powder (feed material), is processed using a plasma apparatus. T he process generally consists of in-flight heating and melting of the feed material by the plasma apparatus. The plasma apparatus contains a plasma torch with required power supply and cooling systems, a powder feeder, a chamber to collect the powder and a dedusting system. The heated powder forms molten spherical droplets that are rapidly cooled under free fall conditions. The plasma densification process removes some impurity oxides, modifies the morphology of the particle and increases the apparent density of the powder.
