    摘要: A passive low pass, &pgr;-type filter of a surface mounted device configuration has two stack capacitors disposed radially inwardly of a coil, otherwise known as an inductor. Each capacitor has a number of ground plates successively stacked between a number of signal plates. The ground plates electrically engage a front and rear ground band which circles the external surface of a non-conductive encapsulant of the filter. A forward and rearward conductive member or sheet engages each end of the encapsulant. One end of the coil is engaged to the front sheet and the opposite end is engaged to the rear sheet. The signal plates of the forward capacitor are engaged to the front sheet and the signal plates of the rearward capacitor are engaged electrically to the rear sheet.

    摘要: A material which possesses both capacitive and inductive properties for suppressing electromagnetic interference is provided, wherein the material is a composite of a ferroelectric material and a ferromagnetic material. The ferroelectric-ferromagnetic composite material is formulated and processed so as to retain the distinct electrical properties of the individual constituents according to the relative quantities of the constituents present in the ferroelectric-ferromagnetic composite material. As a unitary composite element, the ferroelectric-ferromagnetic composite is readily formable to provide a compact electrical filter whose filtering capability is highly suitable for suppressing electromagnetic interference from sources internal and external to an automotive environment. The sintered composite has a very low porosity; interconnectivity between the ferroelectric and ferromagnetic phases; and has no chemical reaction between the ferroelectric and ferromagnetic phases to produce a third phase.

    摘要: A method of producing a miniaturized, fixed volume, internal reference gas chamber comprising the pores of a porous material, suitable for use in a rapid response, highly precise, internal reference, solid electrolyte electrochemical-type oxygen sensor capable of detecting oxygen partial pressures in internal combustion engines operating within lean air/fuel mixtures is accomplished using a four step technique. A thin film layer of material is deposited onto a supporting substrate and patterned, said material comprises at least one component resistant to a subsequent removal step and at least one sacrificial component not resistant to the same subsequent removal step. The said material is then sealed everywhere except at an external orifice. The sacrificial component of said material is then decomposed and removed during a removal step, providing an interlocking network of porosity comprised within the porous component of said material. The internal reference gas chamber is positioned adjacent to the electrodes of the sense and pump cells comprised within the oxygen sensing device.

    摘要: Exemplary embodiments of the invention include a thermoelectric material having an aligned polarization field along a central axis of the material. Along the axis are a first atomic plane and a second atomic plane of substantially similar area. The planes define a first volume and form a single anisotropic crystal. The first volume has a first outer surface and a second outer surface opposite the first outer surface, with the outer surfaces defining the central axis passing through a bulk. The bulk polarization field is formed from a first electrical sheet charge and a second opposing electrical sheet charge, one on each atomic plane. The opposing sheet charges define a bulk polarization field aligned with the central axis, and the bulk polarization field causes asymmetric thermal and electrical conductivity through the first volume along the central axis.
