Abstract: A protective packaging sheet which is particularly suitable for packaging heavy loads such as coils of sheet steel. The packaging sheet is formed from a plastics sheet material having inherently relatively low compressions strength and resistance to impact forces and bending. These mechanical properties are vastly improved in the embossed packaging sheet. At least one of the surfaces of the sheet material is provided with shaped protuberances juxtaposed with adjacent shaped protuberances to provide a gap around each shaped protuberance. The shaped protuberances are arranged in such a way that all straight lines projected onto the surface cut through the shaped protuberances in addition to the gaps.

Application to monopole or dipole type antennas working in the frequency ranges corresponding to the HF, VHF or UHV bands.

Abstract: The invention relates to a helmet with retractable visors for fast day/night reconfiguration. For that, the helmet (1) is designed at the articulations of the visors to allow the use of articulations that can be disassembled without tools. The day visor (15) is thus made modular and removable and is mounted on the helmet by a translational movement in a direction (F) allowing the upper part (16) to engage in a saggital guide rail of the helmet and allowing rotation axes of the helmet to engage in the articulation part of the lateral arms (8) of the visor, locking being effected by hand using a pivoting lever (8). For night missions, the day visor is removed and replaced with a night module mounted on the helmet using the same type of articulation. The invention applies in particular to helmets for aircraft pilots, allowing unprepared ejection.

Abstract: First digital audio-visual program video component(s) are switched on a second digital audio-visual program video component(s) by switching on the beginning of the first set of images including an Intra-coded picture of the second program video component encountered after the switching command. In the transmission order of images, each bidirectionally predictive-coded picture of the first set of images referring to the set of images pertaining to the set of images preceding it before switching, is substituted for a bidirectionally predictive-coded picture of the video coding which is produced independently of (1) the substituted image content and (2) the contents of the images to which it refers.

Abstract: A method for manufacturing vertical GaN light emitting diodes starts by forming a light emitting structure on a sapphire substrate, said light emitting structure including a first conductive GaN clad layer, an active layer and a second conductive GaN clad layer. The light emitting structure is divided into plural units so that the first conductive GaN clad layer of a thickness of at least approximately 100 Å remains. A conductive substrate is attached to the divided upper surface of the light emitting structures using a conductive adhesive layer. A lower surface of the sapphire substrate is irradiated by laser beam so that the sapphire substrate is removed from the unit light emitting structures. First and second contacts are formed respectively on the surfaces of the first conductive clad layer and the conductive substrate. Finally, the resulting structure is cut into plural unit light emitting diodes.

Abstract: Described is a method for fabricating ceramic chip packages in which an epoxy resin containing fine ceramic particles is applied on a ceramic substrate provided with chip packages respectively having a plurality of chips mounted thereon, thereby improving reliability and endurance of the package and miniaturizing the size of the package. The epoxy resin is applied on the ceramic substrate provided with a plurality of the chips mounted thereon except a designated region, thereby minimizing the deformation of the substrate. The epoxy resin layer is formed on the substrate by two steps including a first step for forming a first epoxy resin layer serving as a dam and a second step for forming a second epoxy resin layer, thereby reducing the amount of the used epoxy resin and improving reliability and endurance of the package against temperature and humidity.
