摘要： A video projector including a light source used to display an image, an optical component that differs from the light source, a power supply unit that supplies power, and a centrifugal fan including a rotation shaft and a blade that rotates about the rotation shaft. The centrifugal fan is a double intake fan that draws in gas from first and second axial directions, which are parallel to the rotation shaft, by rotating the blade and sends the gas outward in a radial direction from the rotation shaft. The centrifugal fan sends gas that has cooled the optical component and the power supply unit to the light source.

摘要： A method for reducing eddy currents caused by the gradient magnetic field in a magnetic resonance system employs an anti-eddy current device formed by a number of laminated metallic plates, and includes the steps of calculating the distribution of the main magnetic field of the magnetic resonance system in the anti-eddy current device, calculating the distribution of the main magnetic field and the gradient magnetic field in the anti-eddy current device, subtracting the calculated distribution of the main magnetic field in the anti-eddy current device from the calculated distribution of the main magnetic field and the gradient magnetic field in the anti-eddy current device, to obtain the distribution of the gradient magnetic field in the anti-eddy current device, and adjusting the setting of the metallic plates of the anti-eddy current device based on the distribution of the gradient magnetic field in the anti-eddy current device, so as to reduce the eddy current. The adjustment in the metallic plates of the anti-eddy current device should be such that the gradient magnetic field is parallel to or substantially parallel to the plane of the metallic plates. The metallic plates can be further divided into a number of areas, or the laminating direction of the metallic plates in different areas can be adjusted according to the specific distribution of the gradient magnetic field to obtain the optimum effect of eddy current reduction.

摘要： Techniques for removal of photolithographic films used in the manufacture of semiconductor devices are provided. A substrate support member of a first processing chamber includes at least three retractable pins capable of elevating a wafer from a surface of the substrate support member. In addition, the first processing chamber is configured to automatically maintain the substrate support member at a first temperature. The wafer is elevated from the surface of the substrate support member using the at least three retractable pins. Thermal heating of the substrate from the substrate support member is reduced. A photoresist layer of the substrate is etched away while the substrate is in an elevated position. An anti-reflective layer of the substrate can be etched to remove substantially all of the anti-reflective layer. In a specific embodiment, the anti-reflective layer includes a DUO™ Bottom Anti-Reflective Coating by Honeywell International Inc.
