Patent CA-2241765-A1 (CA)
Title: Solid-state relay
Inventor: SUZUMURA MASAHIKO
IPC: H01L23/495
Filed: 1998-06-26
Abstract: A solid state relay composed of a series connected pair of LDMOSFETs has a minimized output capacitance. Each LDMOSFET is configured to have a silicon layer of a first conductive type, a drain region of the first conductive type diffused in the top surface of the silicon layer, a well region of a second conductive type diffused in the silicon layer in a laterally spaced relation from the drain region, and a source region of the first conductive type diffused within the well region to define a channel extending between the source region and a confronting edge of the well region along the top surface of the silicon layer. Each LDMOSFET is of an SOI (Silicon-On-Insulator) structure composed of a silicon substrate placed on a supporting plate, a buried oxide layer on the silicon substrate, and the silicon layer on the buried oxide layer. The well region is diffused over the full depth of the silicon layer to have its bottom in contact with the buried oxide layer, so that the well region forms with the silicon layer a P-N interface only at a small area adjacent the channel. Because of this reduced P-N interface and also because of the buried oxide layer exhibiting a much lower capacitance than the silicon layer, it is possible to greatly reduce a drain-source capacitance for minimizing the output capacitance of the relay in the non-conductive condition.

Title: Process for the production of lignin and microcellulose
Inventor: BURKART LEONARD
IPC: D21C3/20
Filed: 1997-02-28
Abstract: The method of the invention involves treating cellulosic vegetable matter (the "Feed Stocks") for the selective recovery of lignin (when present in the feed stock), cellulose and hemicelluloses by: (1) reducing the material to be processed to an appropriate size; (2) adjusting the moisture content of the ligno-cellulosic feed stock to 15 percent to 30 percent water; (3) impregnating the ligno-cellulosic feed stock with an extraction liquor containing a glycol and an organic or Lewis acid; (4) rapid heating of said impregnated feed stock to a temperature of about 118 ~C to about 145 ~C; (5) maintaining the desired temperature for about 1 minute to about 6 minutes to solubilize the lignin therefrom (a period of about 2 minutes to about 5 minutes is preferred); (6) stopping the reaction immediately by lowering the temperature to < 100 ~C in a quenching bath of fresh or recycled liquor or other suitable liquid; (7) removing the lignin-enriched extraction liquor from the quenched impregnated matter and (8) recovering the extracted lignin. If the feed stock is non-ligneous (for example, cotton linters), the quenching step (step 6) may be combined with a wash (alcohol is exemplified) to remove the cooking liquor from the cooked material. The cellulosic material may then be recovered from the liquid using separatory means known in the art such as filtration, centrifugation or vacuum screening. Alcohol may be recovered by evaporation under reduced pressure. An improved means of converting the cellulose fraction to microcrystalline cellulose employs using ultrasonic means.

Patent CA-2264144-A1 (CA)
Title: Microbial remediation reactor and process
Inventor: STORMO KEITH E
IPC: B01J19/18
Filed: 1997-09-03
Abstract: Embodiments of a remediation reactor and mixer/contactor blade for the reactor are shown and described, the reactor (11) being for containing a liquid slurry, suspension or settled bed of solid particles containing mi-croorganisms. Inside the vessel is a supply conduit and at least one generally horizon-tal stirrer blade (27) in fluid connection with the supply conduit. The stirrer blade is a mixer/contactor which has a leading side hav-ing openings through which fluid may pass.  The stirrer blade rotates in the vessel, and this rotation is made easier by the hydraulic forces of fluid flowing out from the stirrer blade. The flowing fluid creates a fluidization zone in the slurry, suspension or settled bed at or near the leading edge of the stirrer blade.  The fluidization zone is less dense than the rest of the sediment bed, and the stirrer blade tends to rotate into the fluidization zone. This way, controlled rotation of the stirrer blade may be created near the bottom of the vessel, enhancing mixing of the microorganisms with the slurry, suspension or settled bed in the vessel, without unnecessarily damaging the microorganisms, especially when the flowing fluid contains contaminants which are nutrients for the microorganisms. Also, shown and described is a vessel which incorporates a mixing blade through which a gas and/or a liquid is recirculated. The mixing blade is rotated through a sand layer or other settled bed of solid particles, which acts as a medium supporting microbial growth and/or as a filter to remove particulate matter from the vessel effluent which is drawn off from below the settled bed layer. Fluid recirculation aids in the fluidization of the filter medium and allows for intermittent operation with a significant reduction in energy and operating costs. The vessel may be operated as an aerobic bioreactor by recirculating air or as an anaerobic bioreactor by recirculating an inert gas. Rotation of the mixing blade through the filter medium with recirculation of fluids through the mixing blade allows the filter medium to be efficiently backwashed in order to prevent filter plugging.

La pression hydrostatique reste donc constante au niveau des orifices (31) de la tête d'impression lorsque cette dernière (12) est tournée.
