Title: Method of fabricating an oxide layer on a silicon carbide layer utilizing n2o
Inventor: LIPKIN LORI
IPC: H01L29/24
Filed: 2001-10-01
Granted: 2012-06-26
Abstract: Methods for fabricating a layer of oxide on a silicon carbide layer are provided by forming the oxide layer by at least one of oxidizing the silicon carbide layer in an N~2O environment or annealing an oxide layer on the silicon carbide layer in an N~2O environment. Preferably, a predetermined temperature profile and a predetermined flow rate profile of N~2O are providing during the oxidation or the anneal. The predetermined temperature profile and/or predetermined flow rate profile may be constant or variable and may include ramps to steady state conditions. The predetermined temperature profile and/or the predetermined flow rate profile are selected so as to reduce interface states of the oxide/silicon carbide interface with energies near the conduction band of SiC.

Title: Telecommunications initiated data fulfillment system
Inventor: BRAGER BARRY
IPC: G06Q20/00
Filed: 2001-10-23
Granted: 2009-02-10
Abstract: A system for providing a wide range of telecommunications initiated data fulfilment services in which a multi-function code, such as "# (star, pound), input into an originating telecommunications device, such as a conventional land-line or wireless telephone, triggers the treatment of the input sequence as a multi-function code service request rather than a dialed directory number. The multi-function code is followed by an input data string to complete the multi-function code service request, which the user typically enters into the telecommunications device just like a conventional telephone call, except that the input string begins with the multi-function code. The telecommunications system recognizes the multi-function code as a trigger, and in response takes one or more actions, such as automatically terminating the call to an announcement and routing a data message to a data fulfilment centre, which response to the message by implementing a response action indicated by the multi-function code service request. For example, the data fulfilment centre may respond by transmitting a message over a wireless data network or the Internet to implement a service, such as activation of a vending machine, remote control of device, delivery of a message over the Internet or wireless data network, initiation of an interactive Internet session with the originating device, or a wide range of other services. In addition, a charge for this service may be automatically charged to an account associated with the originating telecommunications device, which may be billed separately or incorporated on the user's conventional monthly telecommunications invoice.

The apparatus comprises web feeding means by which a web material is intermittently fed for a length along a longitudinal feeding path. The web material comprises: two or more layers of plastic film. Web cutting means is disposed along the feeding path. The web cutting means has a shape corresponding completely or incompletely to the shape of circumference of plastic bag so that the web material can be cut into the shape of circumference of plastic bag by the web cutting means whenever the web material is intermittently fed and temporarily stopped, to successively make the plastic bags with a waste kept continuous. The web cutting means comprises partially cutting means. The plastic bag has an upstream edge along which the web material is partially cut by the partially cutting means so that the plastic bag can be kept connected with the waste at the upstream edge of plastic bag. Drawing means is disposed downstream of the cutting means. The waste is diverged from the plastic bag, directed to and drawn by the drawing means after the web material is cut. Discharge means is disposed downstream of the cutting means. The plastic bag is directed to the discharge means without the waste. The plastic bag is then pulled by the discharge means to be torn from the waste at the upstream edge of plastic bag. The plastic bag is then discharged by the discharge means.

Granted: 2010-07-27
Abstract: A catalyst for purifying exhaust gases includes a substrate including an exhaust-gas passage, a coating layer formed on the exhaust-gas passage, and a catalytic ingredient loaded on the coating layer. A loading density of the catalytic ingredient on an upstream area discriminated from a downstream area by a predetermined length from an upstream end of the substrate is greater than a loading density of the catalytic ingredient on the downstream area. The catalytic ingredient is loaded more on the downstream area of the exhaust-gas passage than on the upstream area thereof. Thus, it is possible to suppress the catalytic ingredient being poisoned by poisoning substances.

Abstract: A reduced component wear valve (10) is comprised of a valve body (12) having a passage therethrough and a disc (14) attached to a rotatable shaft (38). The disc is utilized with a seal (18) forming a gap between the disc and the seal proximate to the rotational axis (16) of the disc. When the disc is in the open position, the seal major axis is greater then the disc diameter and they do not touch. As the disc rotates to near closure, the disc perimeter engages the minor axis of the seal (which is smaller than the disc diameter), and the disc stretches the seal in the minor axis direction thus decreasing the major axis such that the gap is closed. The seal can be pre-formed in an elliptical shape or it can be formed into an elliptical shape by a retaining mechanism.  The seal may be a single-piece or a multi-piece assembly press-fit into the valve body. Zero or light disc to seal contact during the majority of the valve disc rotation minimizes valve seal wear and rotational friction.
