20140286471 | INTERTIAL CONFINEMENT FUSION POWER PLANT WHICH DECOUPLES LIFE-LIMITED COMPONENT FROM PLANT AVAILABILITY - An architecture for a fusion power plant is disclosed. The plant includes a fusion chamber for producing neutrons from a fusion reaction, and a laser system in which lasers are arranged about a vacuum chamber to provide energy to the fusion chamber to initiate the fusion reaction. The beam paths between the lasers and the fusion chamber are configured to prevent neutrons from the fusion chamber from reaching the laser system at a level that would preclude human access to the laser system. | 2014-09-25 |
20140286472 | SEMICONDUCTOR DEVICE AND MEASUREMENT METHOD - The present invention provides a semiconductor device and a measurement method that enables high precision measurement of temperature or humidity or the like over a wide range. A semiconductor device of the present invention determines which is faster out of a reference oscillation and a thermistor oscillation, and using the faster oscillation as a reference, measures a count value based on the other oscillation. Moreover, the count based on the faster oscillation is employed as a reference value, and a count value based on the other oscillation when the reference value is taken as a measurement value. A frequency ratio is computed based on the reference value and the measurement value, and based on the computed frequency ratio, a table expressing correspondence relationships between frequency ratio and temperature is referred to and a temperature acquired. | 2014-09-25 |
20140286473 | ESTIMATION OF XRF INTENSITY FROM AN ARRAY OF MICRO-BUMPS - A method for inspection includes capturing an optical image of one or more features on a surface of a sample and irradiating an area of the sample containing at least one of the features with an X-ray beam. An intensity of X-ray fluorescence emitted from the sample in response to the irradiating X-ray beam is measured. The optical image is processed so as to extract geometrical parameters of the at least one of the features and to compute a correction factor responsively to the geometrical parameters. The correction factor is applied to the measured intensity in order to derive a property of the at least one of the features. | 2014-09-25 |
20140286474 | X-Ray Fluorescence Analyzer - An X-ray fluorescence analyzer includes a sample stage having an opening at an X-ray irradiation position, an X-ray source which irradiates a sample placed on the opening with a primary X-ray from below, a detector which detects an X-ray fluorescence generated from the sample, a transparent drop prevention plate supported to be advanced and retracted immediately below the opening, a drive mechanism which advances and retracts the drop prevention plate, an observation camera which observes the drop prevention plate positioned immediately below the opening, and an operation unit which processes an image of the drop prevention plate which is captured by the observation camera. The operation unit detects a foreign matter on the drop prevention plate based on an image difference between images before and after the drive mechanism moves or vibrates the drop prevention plate within an observation range of the observation camera. | 2014-09-25 |
20140286475 | INTERFEROMETER AND OBJECT INFORMATION ACQUISITION SYSTEM - An interferometer includes a diffraction grating that forms a first pattern by diffracting X-rays; a shield grating that forms a second pattern by blocking one or more of the X-rays forming the first pattern; a detector that detects information on the second pattern by detecting X-rays from the shield grating; and a scanning unit that shifts relative positions of an object and a measurable range. In the interferometer, the detector acquires a first detection result by performing a detection while the measurable range and the object take first relative positions and acquires a second detection result by performing a detection while the measurable range and the object take second relative positions. In the interferometer, the scanning unit shifts the relative positions of the measurable range and the object so that a pattern of the first detection result and a pattern of the second detection result pattern have continuity. | 2014-09-25 |
