摘要:
A fiber Bragg grating (FBG) based sensor is used as a strain sensing element to determine frame foot loading of a generator. Three FBGs may be used in tandem to form a basic Frame Foot Loading Module (FFL Module). Two modules are fixed on each vertical support gusset at the corner of the generator frame, with one module on the front of the gusset and a second module on the back of the gusset. Thus, each gusset may be instrumented with six FBG strain gauges or sensors. The gussets are chosen on each of the four corners of the generator. For two-pole generators the first three gussets at each corner may be used and, for four-pole generators the first four gussets may be used.

According to one aspect of the present invention, a substrate processing system is provided. The system may include a chamber wall enclosing a chamber, a substrate support positioned within the chamber to support a substrate, an electromagnetic radiation source to emit electromagnetic radiation onto the substrate on the substrate support, the electromagnetic radiation causing photoelectrons to be emitted from a material on the substrate, an analyzer to capture the photoelectrons emitted from the substrate, and a magnetic field generator to generate a magnetic field within the chamber and guide the photoelectrons from the substrate to the analyzer.

A development station in an electrostatographic imaging machine impedes the flow of carrier particles out of the development station as the developer moves from an upper to a lower magnetic roll. The development station includes a developer housing, for retaining a quantity of developer having semi-conductive carrier particles and toner particles, a first magnetic roll having a stationary core with at least one magnet and a sleeve having longitudinal grooves that rotates about the stationary core of the first magnetic roll to present developer on one side of the first magnetic roll to the photoreceptor, a second magnetic roll having a stationary core with at least one magnet and a sleeve having longitudinal grooves that rotates about the stationary core of the second magnetic roll to receive developer from the first magnetic roll and present developer on one side of the second magnetic roll to the photoreceptor, the second magnetic roll being vertically displaced from the first magnetic roll so that a gap exists between the first and the second magnetic rolls, and a magnetic seal located in the gap between the first and the second magnetic rolls to impede the outflow of carrier particles from the developer moving from the first magnetic roll to the second magnetic roll.

The present invention includes a radio-controlled toy racing car having an elongate, light-weight tubular body constructed of polymeric material. Rotatably mounted on the front end of the body is a front wheel and steering shaft for controlling the directional turning movements of the car. The car is supported at its rear end by a pair of wheels mounted on the respective outer ends of an axle extending laterally from the body, and is driven by an engine pivotally mounted on the body adjacent the rear end thereof. A spoiler is pivotally mounted on the body and behind the engine at a position near the rear end of the body and above the center of the axle to utilize the wind force of the drive engine's propeller to exert a downward and stabilizing force on the rear wheels. Further, a braking element comprising a parachute is housed within the body near the rear end thereof. Control of front wheel movement, engine operation, and parachute deployment are effected remotely from a radio transmitter sending signals to a receiver and separate control elements mounted on the body for the front wheel, engine, and parachute.

A time-of-flight analyzer, such as a secondary ion surface analyzer, and method are disclosed wherein a beam of charged particles is created, magnified, directed along a path to a detector, detected and the time of flight measured. An emission lens is positioned on the path to produce the magnification and an additional lens can be provided along the path to produce variable magnification. A field aperture along the path limits the size of the image and a contrast diaphragm limits the lateral ion velocity. Two or more, preferably three, particle steering analyzers are sequentially positioned along the path from the emission lens to the detector with each of the three analyzers steering the particles through substantially 90 degrees.

Systems and methods for characterizing films by X-ray photoelectron spectroscopy (XPS) are disclosed. For example, a system for characterizing a film may include an X-ray source for generating an X-ray beam having an energy below the k-edge of silicon. A sample holder may be included for positioning a sample in a pathway of the X-ray beam. A first detector may be included for collecting an XPS signal generated by bombarding the sample with the X-ray beam. A second detector may be included for collecting an X-ray fluorescence (XRF) signal generated by bombarding the sample with the X-ray beam. Monitoring/estimation of the primary X-ray flux at the analysis site may be provided by X-ray flux detectors near and at the analysis site. Both XRF and XPS signals may be normalized to the (estimated) primary X-ray flux to enable film thickness or dose measurement without the need to employ signal intensity ratios.
