    Abstract: Un elemento de calentamiento con resistencia, la película delgada y granárea (21, 46, 81) incluyendo un substrato relativamente rígido (22, 63, 82), que retendrá sus propiedades mecánicas a temperaturas elevadas, una película eléctricamente conductora (26, 64, 84) depositada en el substrato (21, 46, 81), y terminales eléctricas (31, 66, 86) que se proporcionan en la película (26, 64, 84). Un substrato metálico (22, 63), tal como una hoja de acero , que tiene una capa basada en cerámica electricamente aislante (23, 62, 83) puede emplearse encima, o en forma alterna, una hoja o placa de micanite (61) puede emplearse. El substrato y película tienen una área que es suficientemente grande de manera tal que el calentador puede operar a temperaturas máximas sobre 38 degree C (100 degree F) con una densidad de energía menor a aproximadamente 15 watts por 6.45 cm cuadrados (pulgada cuadrada). La película eléctricamente conductora de preferencia es una película de oxido de metal tal como oxido de estaño, y se emplea como un calentador con resistencia en aplicaciones tales como hornos (41) y calentadores de espacio (81) para permitir suministro de energía para mayor eficiencia.

    Abstract: ©7 Providing an electrical conductor (10) with an insulation layer having a layer of dielectric carrier with magnetically permeable particles dispersed within the carrier, in which homogeneity is maintained in a fluid mixture (18) of a fluid carrier and the particles, the conductor is moved vertically through a die means (16) to coat it with a fluid layer of the mixture, the fluid carrier is dried and thickness of the dried insulation layer is controlled. This control is achieved by monitoring the thickness or diameter of the dried layer and, if a variation exists between the monitored and required values, the rate of fluid flow through the die means is adjusted to adjust the monitored values towards that required.

    Abstract: In providing a dried insulation layer (46) upon conductor (12), a covering fluid layer (46) is initially provided by a process and apparatus in which the layer is formed from composite material (24) comprising magnetically permeable particles homogeneously mixed with a fluid carrier. The fluid layer is formed by passing the conductor through a reservoir of the material and then vertically through a die (26, 64). The reservoir of fluid applies pressure atthe die orifice and this pressure is adjustable to vary the rate at which the material passes through the orifice and thus varies the diameter. This pressure is controllable by adjusting the height of the reservoir above a die orifice or by adjusting gas pressure acting downwardly upon the material. The diameter of the layer is advantageously measured after it is dried and variation in measured diameter from that desired effects a change in pressure to alter the diameter towards that desired. The diameter of the layer may, however, be measured with the layer in fluid form.

    Abstract: A method for making a substrate for use in a multilayered integrated circuit or multichip module which includes coating a conductive material (14) on a surface of a support sheet (10) to form a conductive circuit (12) and then drying the sheet. Next, a coating of a layer of dielectric layer (18) is placed on the support surface in the areas where the conductive material is not cast. After which the coated sheet is densified to form a densified conductive circuit embedded dielectric layer. A second coating of a dielectric (28) is placed over the first densified conductive circuit embedded dielectric layer such that the second layer is characterized by vias (30) therein which are in register with at least a portion of the conductive circuit (12). The vias in the second dielectric layer are filled to form electrically conductive vias and then densified to form the substrate (44).
