  • Publication number: 20230299870
    Abstract: An information leakage prevention shield device includes a control unit to output a frequency setting signal for setting a filter frequency for an electromagnetic wave emitted from a device, and a modulation signal based on a time variation pattern for sequentially instructing a plurality of different transmission characteristics over time, and a dynamic electromagnetic-wave filter having a filter frequency set by a frequency setting signal from the control unit, having the plurality of different transmission characteristics over time set by the modulation signal from the control unit, to transmit an electromagnetic wave other than the filter frequency set by the frequency setting signal, and to have the plurality of different transmission characteristics over time set by the modulation signal with respect to the filter frequency set by the frequency setting signal.

  • Patent number: 5073451
    Abstract: The invention provides a heat insulating glass plate with a multilayer coating which is fairly low in transmittance for solar radiation and fairly high in transmittance for the visible light and also for radio waves. The multilayer coating is a lamination of transparent and dielectric layers and has three essential layers in which the middle layer is higher or lower in refractivity than the inner and outer layers. The coating may have five layers in which the second and fourth layers are higher or lower in refractivity than the remaining three layers. Each layer of the multilayer coating is a metal compound film deposited by sputtering or CVD. In a first embodiment of the three-layer coating each of the inner and outer layers is formed of SnO.sub.x, ZrO.sub.x, TaO.sub.x or AlN.sub.x having a refractive index of 1.8-2.1 and the middle layer is formed of TiO.sub.x having a refractive index of 2.2-2.5. In a second embodiment, each of the inner and outer layers is formed of SnO.sub.x, TiO.sub.x, ZrO.sub.x, TaO.

  • Patent number: 4985312
    Abstract: The invention provides a heat reflecting glass plate with a multilayer coating on a transparent glass plate. The multilayer coating comprises a film of indium-tin oxide (ITO) of Al=N deposited on the glass surface, a heat reflective film of Ag or Cu deposited on the ITO or AlN film to a thickness of 40-200 .ANG., a metal Zn film deposited on the Ag or Cu film to a thickness of 20-200 .ANG. and an ITO or AlN film as the outermost layer. The multilayer coating may further comprise at least one set of the Ag or Cu film, metal Zn film and ITO or AlN film such that each Ag or Cu film overlies an ITO or AlN film and is overlaid with a metal Zn film and that the outermost layer is an ITO or AlN film. The multilayer coating is excellent in the fundamental characteristics as a heat reflecting and transparent coating and also in moisture resistance.

  • Patent number: 4869948
    Abstract: The invention relates to a transparent glass board for use in document copying machines as the copying glass on which each sheet of original documents is placed and, in the case of copying machines of automatic document feed type, is forced to slide. To ensure good copying and smooth sliding carriage of original paper sheets, a transparent antistatic coating layer using tin oxide and/or indium oxide is formed on one or each of the top and back surfaces of a transparent glass, and a transparent lubricative coating layer using an organic silicon compound having isocyanate groups attached to Si atom is formed on the top side of the glass plate so as to provide a top surface with which each sheet of documents comes into contact. The antistatic layer has a thickness of 300-1500 .ANG. and the lubricative layer has a thickness of 300-2000 .ANG..
