Abstract: ABSTRACT OF THE DISCLOSURE             This invention is directed to a high temperature resistant lighting device for lighting the interior of a high temperature furnace for observing the furnace interior from the outside.  A lighting lamp and an inspection device are housed within a metallic heat protective casing having a cooling path for circulation of cooling water.  The lamp and an objective section of the inspection device are rotatable with its associated drives and so that the illuminating direction of light from the lamp and the viewing direction of the objective section are variable so as to direct illuminating light beams from the lamp toward a wall surface of the furnace via a viewing window and focus reflected light beams from the wall surface of the furnace onto the objective section.          The light beams focused on the objective section are led out of the furnace through an optical fiber bundle or cable and picked up to form a video image of the wall surface of the furnace by means of a TV camera.  Accurate and scrupulous observation of the inner wall surface of the furnace is made possible by varying the directions of the lamp and the objective section.

Abstract: ABSTRACT OF THE DISCLOSURE     A double heterostructure semiconductor laser device comprises; a composite structure including a semiconductor substrate of one conductivity type and a first semiconductor layer disposed on the semiconductor substrate. The composite structure has a first level and a second level higher than the first level to an extent of the thickness of the first semiconductor layers or more.  The transition between the first and second levels is in the propagation of the laser radiation and has a slant crystal face.  The first semiconductor layer on the second level has a periodic structure of a pre-scribed pitch of thickness formed along the side thereof in the propagation of the laser radiation.  A second semiconductor layer of one conductivity type is formed on the first and second levels, having a greater bandgap than that of the first semiconductor layer.  The second semiconductor layer is separated into two portions in the extension of the slant crystal face.  A semiconductor active layer is formed on the second semiconductor layer, having a smaller bandgap than that of the second semiconductor layer.  The ends of the semi-conductor active layers and first semiconductor layer abut in the extension of the slant crystal face.  A third semiconductor layer of the opposite con-ductivity type is formed on the semiconductor active layer, having a greater bandgap than that of the semiconductor active layer, whereby the application of a forward bias to the semiconductor active layer produces stimulated emission of radiation.

Abstract: Process for the electron beam curing of coating compositions Abstract:        The electron beam curing of ethylenically unsaturated coating compositions can be accelerated by the addition of sterically hindered amines.  These amines are at the same time light stabilisers for the cured coating.  2,2,6,6-Tetra-alkylpiperidine derivatives are examples of such amines.  If a UV absorber is added to the coating compositions in addi-tion, a synergistic increase in the light-stabilising effect occurs.
