摘要： A monolithic chip capacitor in which the electrode layers are bonded together at an edge. The capacitor includes an electrically conductive substrate that is electrically connected to the bonded edges of the electrode layers. The capacitor body has end terminal surfaces defined by electrically conductive material across one end of the body that is in electrically conducting contact with the substrate. In one form, the termination material is a folded end of the substrate itself. In another form, an end cap which can be thicker than the substrate, is folded to define the termination surface and to provide another surface in good electrical contact with the substrate.

The preferred halogenated benzene is trichlorobenzene, and the preferred alkyl branched chain phthalate ester is di-2-ethylhexylphthalate.

摘要： A monolithic multi-layer capacitor having a central capacitively active area and two electrode joining section separated from the active area by sloped sections has dielectric layers about 1 micron thick in the active area which taper gradually to zero thickness in the sloped sections. Electrode layers in the active area have a thickness in the range from 200 to 500 Angstroms and sufficient thickness throughout the sloped sections for adequate current carrying capacity. Various acrylates are used for the dielectric layers, the number of layers ranging from a few to many thousands.Apparatus and methods for the fabrication of such capacitors on a high speed, production scale basis employ techniques for the flash evaporation of highly reactive monomers of acrylate dielectric materials. The vapor is controllably directed to a deposition surface for condensation and subsequent curing by a field enhanced gas discharge electron beam source. The control of the dielectric vapor is accomplished by adjacent gas streams of an inert gas directed to areas of the deposition surface where deposition of the electrode material is unwanted. Monomers of the dielectric material are ultrasonically atomized in preparation for flash evaporation.

摘要： Sheet capacitive materials for use in forming a thin-film capacitor comprise an electrically nonconductive substrate, a layer of electrically conductive material disposed a surface of the substrate, and a layer of electrically nonconductive material disposed onto a surface of the conductive material layer. The conductive material layer includes a contact area along a first lengthwise edge of the substrate that is thicker than remaining portions of the material layer. A portion of the substrate adjacent a second lengthwise edge remains exposed. The electrically nonconductive material includes an anti-stick component, and covers the exposed substrate surface and a major portion of the material layer except for the contact area. A first and second sheet is constructed having contact areas along opposite lengthwise edges. The sheets are placed together so that the contact areas are oriented at opposite lengthwise edges, and are staggered so that the contact areas remain exposed. The sheets are wound together in a spiral to form a roll having a contact area at each respective end. Metal is sprayed onto the exposed contact areas to form capacitor electrodes. A thin-film capacitor formed from such sheet capacitive materials have improved properties of corrosion resistance and self healing when compared to conventionally constructed thin-film capacitors.

摘要： Acoustic echos are canceled by employing a first echo canceler having a comparatively long first impulse response synthesis capability which is connected between a transmit path and receive path for generating a first error signal and for canceling echo signals in the transmit path, and at least a second echo canceler having a comparatively short second impulse response synthesis capability connected in parallel with the first echo canceler between the transmit and the receive path. The second echo canceler is supplied with the first error signal from the first echo canceler and is adaptively operating simultaneously with but independent of the first echo canceler to further cancel echos in the transmit path. Specifically, the first echo canceler is intended to capture the substantially stationary and any slowly varying components of the echo path impulse response, and the second echo canceler is intended to capture the more time varying, i.e., dynamically varying, component of the echo path impulse response.
