摘要： Multilayer magnetic components can be made with reduced cracking and magnetic degradation by forming layers having patterns of magnetic and insulating regions separated by regions that are removable during sintering. Advantageously, when the layers are stacked, layers of removable material are also disposed between magnetic regions and insulating regions so as to produce upon sintering a magnetic core within an insulating body wherein the core is substantially completely surrounded by a thin layer of free space.

摘要： This invention is directed to a process of producing semiconductor devices which involves deposition of protective glass layers by a particle beam technique from targets of phosphosilicate glass, as well as a process for production of such targets. The phosphosilicate glass containing 1-15 mole percent P.sub.2 O.sub.5 is produced by a sol/gel technique which involves mixing of a fumed silica, with a surface area of 50-400 m.sup.2 /g, preferably about 200 m.sup.2 /g, with phosphoric acid and water to form a sol with 20-55 wt. % silica, allowing it to gel, drying at ambient conditions, dehydrating at about 650.degree. C. in an atmosphere of an inert gas and chlorine and fluorine containing gases, heating up at a certain rate of from 100.degree. to 180.degree. C. per hour to a peak sintering temperature below 1200.degree. C. and cooling so as to produce amorphous and transparent glass suitable for use as a target. The glass layers are highly advantageous as encapsulating layers, diffusion barrier layers, etc., especially for optical type and semiconductor devices. Production of the phosphosilicate glass by the sol/gel technique is highly advantageous over the conventional melting technique, being faster and much less expensive than the latter.

摘要： This invention is predicated upon applicants' discovery that conventional techniques for minimizing metal loss from sintered ceramic materials are not adequate in the fabrication of small ceramic components such as multilayer monolithic magnetic devices wherein a magnetic core is substantially surrounded by an insulating housing. Applicants have determined that this metal loss problem can be solved by providing the component with a housing layer having an appropriate concentration of metal. Specifically, if the insulating housing material around the magnetic core has, during the high temperature firing, the same partial pressure of metal as the magnetic core material, there is no net loss of metal from the core. In a preferred embodiment, loss of zinc from a MnZn ferrite core is compensated by providing a housing of NiZn ferrite or zinc aluminate with appropriate Zn concentrations. Similar considerations apply to other ceramic components.

摘要翻译： 本发明基于申请人的发现，用于最小化烧结陶瓷材料的金属损耗的常规技术在制造小型陶瓷部件如多层单片磁性器件中是不够的，其中磁芯基本上被绝缘壳体包围。 申请人已经确定，通过为组件提供具有适当浓度金属的容纳层，可以解决该金属损失问题。 具体来说，如果磁芯周围的绝缘壳体材料在高温烧成时具有与磁心材料相同的金属分压，则不存在来自芯的金属的净损耗。 在优选的实施方案中，通过提供具有合适的Zn浓度的NiZn铁氧体或铝酸锌的壳体来补偿来自MnZn铁氧体磁心的锌的损失。 类似的考虑也适用于其他陶瓷组件。

摘要： Lowered cost fabrication including preparation of large bodies of void-free, high-silica glass, depends upon gellation of an aqueous sol of colloidal silica particles, followed by drying and firing of such gel. Freedom from cracks in the dried gel is the consequence of included polymeric material which wets the particles. The polymeric material is removed by thermal decomposition attended upon temperature attained in firing.

摘要： The disclosed method of producing optical fiber comprises providing a silica-based glass rod of diameter D that comprises a core region of effective diameter d surrounded by cladding material (D/d typcially>2) and a silica-based porous jacketing tube, inserting the glass core rod into the porous tube, consolidating the porous material and sintering the jacketing tube onto the core rod such that a substantially pore-free optical fiber preform results. Fiber is then drawn from the preform in the conventional manner. Consolidation and sintering is carried out at a temperature below the softening temperature of the material, typically
