Abstract: A direct vessel injection-type pressurized light water reactor (DVI-PLWR), in which an emergency core cooling water (ECC) is directly injected into a downcomer of a reactor vessel, is disclosed. In order to reduce the ratio of ECC bypass from the downcomer to a broken area of a cold leg in the case of a cold leg guillotine break (CLGB), such as a double-ended guillo4tine break (DEGB), a plurality of corrugations, having a V-shaped cross-section, are vertically arranged around each of the inner surface of a pressure vessel and the outer surface of a core barrel at regular intervals, with a vertical groove formed between two neighboring corrugations. The grooves phase-separate the ECC from a high-speed lateral flow of fluid running in the downcomer, and the separated ECC stagnates in the form of vortexes in the grooves, prior to flowing down to the lower section of the downcomer due to gravity.

Abstract: LEDs 5 serving as light sources are arranged so as to face an incidence surface 4 of a light guide plate 3. Light emitted from the LEDs 5 is incident on the incidence surface 4 of the light guide plate 3 to enter the light guide plate 3 to be propagated through the light guide plate 3. When the angle of incidence of the light on an emission surface 6 of the light guide plate 3 is a critical angle or less while the light is propagated, the light leaves the emission surface 6. On at least one of the emission surface 6 of the light guide plate 6 and a surface 10 opposite to the emission surface 6 of the light guide plate 6, a large number of prism protrusions 12 extending in parallel to such a direction that a distance from the incidence surface 4 increases are formed along the incidence surface 4. A side-face side portion 10b of the prism protrusions 12 is formed so as to have a height gradually decreasing as a distance from the incidence surface 4 decreases.

Abstract: After copper plates 14 are bonded to both sides of a ceramic substrate 10 via a brazing filler metal 12, UV curing alkali peeling type resists 16 are applied on predetermined portions of the surfaces of the copper plates 14 to etch undesired portions of the copper plates 14 to form a metal circuit portion. While the resists 16 are maintained, undesired portions of the brazing filler metal 12 and a reaction product, which is produced by a reaction of the brazing filler metal 12 with the ceramic substrate 10, are removed (or undesired portions of the brazing filler metal 12 and a reaction product, which is produced by a reaction of the brazing filler metal 12 with the ceramic substrate 10, are removed, and the side portion of the metal circuit portion is etched). Thereafter, the resists 16 are peeled off, and an Ni—P electroless plating 18 is carried out.

Abstract: A method for the welding of plastic materials in the form of webs, films or the like by means of a heating wedge, welding being carried out without the use of a second pressure roller below the welded material webs. For this purpose, the heating wedge is placed onto the lower material web and is moved over the latter under pressure. The pressure is generated via a holding-down device which has a holding-down roller and which presses onto the upper material web and onto the heating wedge. A floating mounting for the heating wedge compensates for slight unevennesses on the lower material web.
