Patent CA-2438010-A1 (CA)
Inventor: WATANABE KAZUMASA
IPC: D21F3/00
Filed: 2003-08-21
Abstract: A belt for a papermaking machine has minute projections and recesses randomly formed in a shoe-contacting surface of the belt by a powdery material contained in a high molecular weight elastic section formed on a base body. The surface roughness RZ of the shoe-contacting surface is between 50 and 500 microns; the particle diameter of the powdery material is between 5 and 500 microns; and the content of the powdery material in the high molecular weight elastic section is between 5 and 50 percent by weight. A lubricant is held in the minute projections and recesses, and consequently more lubricant may be supplied between the belt and the shoe with which it cooperates. As a result, friction between the belt and the shoe is reduced, and less energy is required to drive the papermaking machine.

Patent CA-2444879-A1 (CA)
Inventor: PARKER ROGER B
IPC: H04L12/28
Filed: 2002-04-26
Abstract: The invention is a system and method to uniquely associate remote wireless Access Points using a switch engine (1). This is necessary in a multi-point wireless network where a central wireless Access Point must be able to receive packets from remote Access Points and then retransmit them, with a modifier, back to the wireless port from which they were received. By using available switch engine hardware (1) this invention takes advantage of lower cost, higher performance and increased features in commodity parts. The invention resolves differences in common Ethernet switch engines that make them unsuitable for direct interface to wireless networks (3) such as that defined by IEEE Standard 802.11 by using an aggregated set of physical ports (4, 5) on the switch engine (1). The method allows the switch engine (1) to operate in its normal manner while satisfying the requirements for switching data packets between the Access Points in a multi-point configuration.

IPC: H01L21/822
Filed: 2002-10-30
Abstract: A semiconductor device is fabricated in a silicon on insulator ~SOI~ substra te including a supporting silicon substrate (10), a silicon oxide layer support ed by the substrate, and a silicon layer overlying the silicon oxide layer. An electrical component is fabricated in the silicon layer over a portion of th e silicon oxide layer (12), and then the substrate opposite from the component is masked and etched. A metal layer (20) is then formed in the portion of th e substrate which has been removed by etching with the metal layer providing heat removal from the component. In an alternative embodiment, the silicon oxide layer overlying the portion of the substrate is removed with the metal layer abutting the silicon layer. In fabricating the device, preferential etching is employed to remove the silicon in the substrate with the silicon oxide functioning as an etchant stop. A two step process can be employed including a first oxide etch to etch the bulk of the silicon and then a more selective but slower etch. Then, the exposed silicon oxide can then be removed, as in the alternative embodiment, by a preferential etchant of silicon oxide.
