Patent JP-H0513380-B2 (JP)
IPC: H01L23/522
Filed: 1985-07-26
Abstract: A silicon circuit board incorporates multiple levels of patterned conductors. First level upper and lower patterned conductors are situated on an insulation-coated, monocrystalline silicon substrate. Upper and lower, high resistivity, polycrystalline silicon layers, in turn, are situated on the first level upper and lower patterned conductors, respectively. Second level upper and lower patterned conductors are situated over the upper and lower polycrystalline silicon layers. Further levels of patterned conductors in the circuit board may be provided by iteratively forming on the board polycrystalline silicon layers and patterned conductors. Conducting feedthroughs in the circuit board provide electrical communication between various patterened conductors.

Abstract: A flexible power transmission belt having a plurality of teeth (13) each of which has a pair of arcuate convex flank portions (21, 22) which in longitudinal cross-section closely approximate to an arc of a circle. Each tooth exhibits a height (H) to width (W) relationship within a predetermined range, and the arcuate flanks each have a pressure angle (a) within a predetermined range. The belt is preferably used in combination with a toothed pulley whose teeth are substantially conjugate to the belt teeth and whose cavities between the teeth have a height to width relationship within another predetermined range and have concave flanks exhibiting a pressure angle in still another predetermined range, said belt tooth width being approximately 0.98 of the pulley cavity width so as to provide a high torque positive drive power transmission system having very low backlash.

Abstract: The disclosure relates to an artificial tooth crown composed of glass ceramics comprising crystallized calcium phosphate forming essentially apatite which is a main inorganic component of natural bones or teeth. The disclosure also relates to a method of producing the artificial tooth crown. The artificial tooth crown has superior dimensional accuracy since it is made by precision casting. The tooth crown can be securely adhered by a dental cement such as glass ionomer. Furthermore, the physical properties of the tooth crown are very similar to those of the natural teeth, and the wear caused by the biting motion between the tooth crown and its mating tooth does not differ from that caused by the biting motion between the natural teeth. Furthermore, the method does not differ from the conventional precision casting method.

Abstract: To unravel a terminal portion of a textile yarn, in particular in preparation for joining that yarn to another one by twisting their ends together, an extremity of the yarn is vibrated to loosen the fibers while a part of the yarn spaced from its end is held fast and the yarn extremity is combed or subjected to an aspirated air stream to remove loose fibers. In a preferred arrangement the air stream also causes vibration of a flexible tongue mounted in an air duct alongside the yarn extremity to oscillate its fibers.
