摘要： An x-ray treatment apparatus includes an x-ray generating device, a head unit, a manipulator and a microwave source. The x-ray generating device produces x-rays, by letting electrons, which have been emitted from an electron gun, be accelerated by a linear accelerator and strike a target. The acceleration of electrons is effected by microwaves. The x-ray generating device is accommodated in the head unit. The head unit is attached to a distal end portion of the manipulator. The manipulator positions the head unit such that x-rays emitted from the head unit may be applied to a part for medical treatment in a patient. The microwave source is disposed at a proximal end portion of the manipulator. Microwaves are propagated from the microwave source to the accelerator through a waveguide.

摘要： The invention provides a semiconductor light emitting device whose operating voltage can be easily reduced, a method of producing the same, and an optical device. An n-type clad layer, a first guide layer, an active layer, a second guide layer, a p-type clad layer, a first semiconductor layer, and a second semiconductor layer of ZnSe are successively grown on an n-type substrate. An alkali compound layer of Na2Se is then formed thereon. Subsequently, a heat treatment is performed by means of irradiation of an excimer laser beam so that at least a part of the second semiconductor layer and at least a part of the alkali compound layer are altered thereby forming a contact layer. Furthermore, a p-side electrode is formed on the contact layer. The contact layer contains an alkali metal serving as a p-type impurity so that the contact layer has a low electric resistance thereby achieving a reduction in the operating voltage and thus a reduction in the operating power. As a result of the reduction in the operating power, the device life is improved.

摘要： A formed article of fiber-reinforced thermoplastic resin which has been adapted for use in a sliding member by restoring the wear resistance once degraded by the addition of reinforcing fibers to the normal level is disclosed. This formed article comprises a fiber-reinforced resin material of a thermoplastic resin containing reinforcing fibers and incorporating therein additionally as a sliding property-imparting agent a material having a storage elastic modulus in the range of 3.5×108 Pa to 5.0×108 Pa in a service temperature range of 30° C. to 70° C. The ratio of incorporation of the sliding property-imparting agent is properly in the range of 4 to 10% by weight when the matrix resin is a polyamide-based resin or 4 to 20% by weight when the matrix resin is a thermoplastic resin other than the polyamide-based resin, respectively based on the total weight of the resin and the reinforcing fibers.
