    摘要: A projector to which a ceiling suspension attachment is fixed. The projector accommodates an internal device. The projector is provided with an outer case including a bottom wall that defines an outer bottom surface and an inner bottom surface of the outer case. Insert nuts are arranged on the bottom wall. Each insert nut includes a threaded hole to which a first coupling screw is fastened and a second coupling screw can be fastened. The first coupling screw couples the attachment to the outer bottom surface of the bottom wall, and the second coupling screw is fastened to the threaded hole from a side opposite to the first coupling screw. The second coupling screw is fastened at least one of the insert nuts to couple the inner device to the inner bottom surface of the bottom wall.

    摘要: A reliquifier using a cryocooler in which an insulated sleeve surrounds a portion of the cold head, a first stage cooling station, and a second stage cooling station, including a condenser. Gas is conveyed from a cryostat to the insulated sleeve, where it is liquefied as it passes over the cold head. An end of the insulated sleeve is connected to a liquid transfer tube for conveying condensed fluid back to the cryostat.

    摘要: A computer implemented method for the verification of concurrent software programs wherein the concurrent software program is partitioned into subsets named concurrent trace programs (CTPs) and each of the CTPs is evaluated using a satisfiability-based (SAT) symbolic analysis. By applying the SAT analysis to individual CTPs in isolation the symbolic analysis is advantageously more scalable and efficient.

    摘要: A system and method for dynamic data race detection for concurrent systems includes computing lockset information using a processor for different components of a concurrent system. A controlled execution of the system is performed where the controlled execution explores different interleavings of the concurrent components. The lockset information is used during the controlled execution to check whether a search subspace associated with a state in the execution is free of data races. A race-free search subspace is dynamically pruned to reduce resource usage.

    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.
