    摘要: Infrared radiation source arrangement, in particular for use in infrared spectral analysis. To an electrically insulating substrate (2) there is applied one and preferably at least two separate electrically conductive films (2a, 2b) adapted to be heated by application of a time dependent electric current thereto. Tow or more films may form a radiation group (array) in which each film (2a, 2b) is adapted to be energized separately with electric current from an electric drive circuit (1) for applying a time dependent, preferably pulse shaped electric current to the film or films, so that infrared radiation pulses are emitted. The electric current is time controlled in order that the radiation pulses from the respective films may be distinguished from each other in a detector (6). The thickness of the substrate and the thermal conductivity, specific heat and density of the substrate material are so chosen that the thermal time constant is adapted to the pulse frequency range of the drive circuit.

    摘要: In a heating and temperature control system for a data storage apparatus comprising at least one matrix-addressable ferroelectric or electret memory device, Joule heating means are provided in the memory device, a temperature determining means is connected with controller circuitry and the controller circuitry is connected with an external power supply, which controlled by the former powers the Joule heating means to achieve a selected operating temperature. In a method for operating the heating and temperature control system an ambient or instant temperature of the memory device is determined and compared with the set nominal optimal temperature, and the difference between these temperatures is used in a predefined algorithm for establishing control parameters for the application of power to the Joule heating means to achieve the selected operating temperature in the memory device during an addressing operation thereto.

    摘要: An optical data storage medium with burn-film having changeable optical properties, for example, changeable reflective power as a result of sufficiently intense illumination, due to hole-burning in the film, is provided with optical structures close to the burn-film for focusing and positioning during recording and reading of individually interpretable data bits (spots). The optical structures are preferably monodisperse, transparent spheres with a diameter in the range of 1-100 .mu.m. Illumination is performed selectively from a number of predetermined angles (.THETA.i, .phi.j) during recording and reading, and the number of individual data spots under each sphere corresponds roughly to the number of angles.
