Abstract: To provide a manufacturing method excellent in controllability, productivity and economics of a high-quality SOI wafer, and a wafer manufactured by that method, in the wafer manufactured by bonding, after bonding, separation is made on an interface of a high porosity layer in a porous region including a low porosity layer and the high porosity layer in a surface formed on a main surface side of a first Si substrate 2 to transfer a non-porous layer onto a second substrate.          After separation at the high porosity layer, a residual low porosity thin layer is made non-porous by a smoothing process such as hydrogen annealing without using selective etching.

Abstract: In an individual section glassware forming system that includes a plurality of operating mechanisms for performing cyclic motions, an electronic controller for controlling cyclic motion at a needle mechanism includes electronic memory for storing a plurality of motion profiles for the needle mechanism, with each of the profiles comprising a set of needle position data versus time data. Any one of the profiles so stored may be selectively displayed as a graph of position versus time. A plurality of control points, consisting of less than all data points, are highlighted on the graphic display at spaced positions along the graph. An operator may identify one of the control points and change the position data and/or time data associated with that control point.  An electronic control computer is responsive to such control point change for automatically recomputing the position data and time data for the profile so as to accommodate the operator-selected changes at the control point.   The recomputed position and time data is graphically displayed, including the plurality of control points at spaced positions along the recomputed graph.   Most preferably, the recomputed graphic data is superimposed on the graph of the initial position versus time data so that the operator can observe the effects of changes in graphic position of the control data points.

Title: Well car structure
Inventor: FORBES JAMES WILFRED
IPC: B61D3/00
Filed: 1998-07-23
Granted: 2008-02-26
Abstract: A railcar unit has a pair of opposed side sills that are joined by structure that performs the function of a web in a deep beam or bracing in a truss. The joining structure is able to transmit loads that are applied transversely to the longitudinal direction of the car from one sill to the other, and is also able to transmit a bending moment couple, in the form of opposite longitudinal tensile and compressive forces, also transmitted to the side sills. The locations at which the transverse forces are imposed on, or by, the intermediate structure have longitudinal slip. When the railcar unit is placed in longitudinal tension under draft loads, the longitudinal slip allows the floor structure not to be subject to the longitudinal draft loads. In the embodiment described the joining structure serves the additional function of acting as a floor panel for vertical loads carried within the well car unit.

Title: Wireless communication device with call screening
Inventor: AMIN UMESH J
IPC: H04W4/00
Filed: 1998-08-11
Granted: 2004-03-30
Abstract: A cellular telephone maintains a screening list of calling party numbers, and specifies call handling therefor. A mobile switching center is responsive to selected types of the specified call handling. The call handling can depend on whether the call is local or non- local, which is affected by the location of the cellular telephone. The call handling can also depend on the time at which the call is made. A subscriber updates his or her screening list via personal computer, and transmits via a communication network the updated screening list to a message center which sends the updated screening list to the cellular telephone via wireless communication. A calling party number can be specified as a wildcard.

Title: Fuel injector nozzle with protective refractory insert
Inventor: BROOKER DONALD DUANE
IPC: B05B15/06
Filed: 1998-06-29
Granted: 2003-05-06
Abstract: The fuel injector nozzle (10) for a gasifier includes a protective recfractory sheath (70) that is flush mounted at a downstream end proximate the nozzle outlet portion (40). The refractory insert (72) is of annular form to surround the nozzle outlet. The annular refractory member can be a one-piece structure or a multi-segment structure. Whether the annular refractory member is a one-piece structure or a multi-segment structure, it is recessed in a downstream end surface of the fuel injector nozzle and retained in the recess by locating pins (110) or by thread-like engagement between a projection (144) and a groove (172) that are provided on complementary inter-engaging surfaces of the recess and refractory member. The enduring presence of the annular refractory member prolongs the service life of the fuel injector by protecting the vulnerable surface areas at the downstream end of the fuel injector nozzle that are close to a hot and corrosive reaction zone within the gasifier.

Patent CA-2322253-C (CA)
Inventor: WILLIAMS MICHAEL G
IPC: H04M1/738

Granted: 2005-04-19
Abstract: A line powered data access arrangement (DAA) is disclosed which adaptively allows proper operation with power supplied from a telephone line as conditions warrant, while at the same time satisfying the relevant requirements of many countries. In the line powered codec, a startup procedure for the international line powered codec uses register settings, e.g., country-specific register settings, which are powered and maintained from the low voltage side (e.g., from the PC or modem side) of the line powered codec. In this way, even during low line power conditions the programmed state of the line powered codec can be maintained, thus a default condition will not necessarily returned to by the line powered codec upon reset due to a power loss in the telephone line. In another aspect, a charge storage device such as a charge capacitor is charged from a charge pump formed from a differential clock signal from the low voltage side. A current and voltage detection module in the line powered codec is always powered from the telephone line. Upon detection of an off/ hook signal or a power down condition, the current detection module determines if/when the current and voltage on the telephone line is sufficient to power certain circuits on the line powered codec. If sufficient power is not present, the line powered codec does not power up. However, the line powered codec will power up if sufficient current is detected. In another aspect, a plurality of power rails may be provided. A first power rail may be associated with the line power, a second power rail may be associated with a low voltage side power source, e.g., a charge storage device. A third (and other) power rails may be switchably connected to either the first power rail or second power rail as line power conditions and on-hook/off-hook conditions warrant.
