Abstract:
A method for making single phase or multiphase permanent magnets having high intrinsic coercivity, in which a molten state salt electrolysis technique is used to produce a variety of magnetic metallic or alloy particles, in controllable sizes. The magnetic particles thus produced are then bonded and formed into permanent magnets.
Abstract:
A three terminal pi filter having embedded electrodes, or a system of embedded electrodes, whereby the embedded structure of the electrodes results in a pi filter having higher insertion losses, better attenuation of unwanted signal power, greater mechanical strength and smaller dimensions than previously known filters.
Abstract:
Broadband low-pass filters containing inductors and/or capacitors wherein resonances of a main inductor and/or capacitor are obviated by utilizing single-turn inductors and/or low distributed inductance capacitors which have no self resonances below 200 MHz. and whose resonances do not coincide with the self resonances of the main components. The auxiliary components are connected so as to maintain the high-insertion loss of the filter at the self-resonant frequencies of the main components.
Abstract:
This invention relates to contacts which have about 0.001 to 96 percent by weight of ferromagnetic or ferrimagnetic permanent magnetic particles embedded in the contacts such that the magnetic particles are distinguishable from the basic contact material. The Curie temperature of the magnetic particles used in the contacts are greater than about 250* C. and the magnetic particles have an average spontaneous magnetic energy product greater than about 5,000 Gauss.Oersted. The magnetic particles having spontaneous magnetic energy can also be incorporated in certain contact configurations to also obtain excellent noise suppression characteristics.
Abstract:
A three-dimensional magnetic core memory system in which the noise effect of partially switched cores on the sensing wires are greatly diminished and the number of connecting points in the system is minimized.
Abstract:
Broad-band high-frequency low-pass filters formed with capacitors which have structures including multilayer and ceramic types and monolayer capacitors. A passive element such as magnetic cores are contained wholly or partially within the capacitor structure. The filter units which may themselves form complete PI filters or L filters may also be combined as the inside portion of a tubular multilayer ceramic capacitor. Rolled capacitors may be used for distributed inductance and magnetic cores in combination with wound inductors or individually may be formed as portions of the filters.
Abstract:
A miniature broadband high frequency low pass filter having at least one multiturn tape wound core inductor and at least one ceramic capacitor whereby the resultant filter exhibits improved insertion loss characteristics even in filter applications having certain amounts of DC or low frequency current passing therethrough.
