METHOD FOR CONTROLLING THE HERMETICITY OF A CLOSED CAVITY OF A MICROMETRIC COMPONENT, AND MICROMETRIC COMPONENT FOR THE IMPLEMENTATION THEREOF
ANALOG SIGNAL INPUT/OUTPUT SYSTEM USING NETWORK LINES
A MODULAR APPROACH TO THE TCP/IPv6 HARDWARE IMPLEMENTATION
High-speed adjusting device for adjusting a switching element between switching positions in a valve device with very small switching times has switchable electromagnets
Measurement resistance, especially for use as shunt, has resistance element with at least 2 flat layers of resistance material separated at flat sides by isolation layer; layers are connected together by bridge of resistance material
Rotary spinning assembly for flame yarn has and output thickness regulator stations coupled to control system
Magnetic memory cell e.g. magnetic random access memory has spacer layer provided between data layer and superparamagnetic layer having magnetic energy less than magnetic energy of data layer
Video signal converter for computer has BIOS for receiving TV selection and initializing signals, input interface, video tuner unit, video acquisition unit, video control unit for receiving detected signal and converting to video signal
Air conditioning device comprises a heating module arranged in a heating housing received by a frame and connected to a central current supply and to a heat exchanger
Planar cutter for a CNC machine comprises a cutting body arranged on a holder and interacting with adjusting elements arranged in the body so that cutting horizon of the cutting plates can be aligned and adjusted in a region
Projection wall used as a large projection wall comprises a batten extending from a housing behind a screen parallel to the axis of a winding shaft
Attached box for lamp controller has circuit board insulating body surface with attachment plate, two mutually isolated current-conducting copper films, contact terminals fed through holes in circuit board, through-holes in insulating body
Foundation pile, e.g. for offshore wind power system, has pile body that carries essentially radially attached vanes at the level of the higher layers of the ground when the pile body is installed
Mobile protective barrier for e.g. building site has coloured and perforated upright plastic lamella
