摘要： A method of making a ceramic core is provided wherein the ceramic core is grit blasted using abrasive grit media particulates directed at the core through a preformed apertured mask or pattern to impart a controlled pattern of surface concavities to the core surface by impingement of the abrasive grit media thereon. Another method of making a ceramic casting core is provided wherein the ceramic core is formed in a molding die having a fugitive textured mask or a permanent textured insert positioned on the die surface to impart a controlled surface texture or roughness to the core surfaces.

摘要： A method of making a sub-miniature “micro-chip” oxygen sensor is provided where multiple sensor elements are applied to a dielectric ceramic substrate consisting of a heater pattern, followed by a dielectric layer. Intermeshing electrodes are then applied either over the heater pattern/dielectric layers or on the opposite side of the substrate. The space between the intermeshing electrodes is filled with an n-type or p-type high temperature semiconductor which is covered by a porous protection layer. After singulation (dicing), the sensor element is assembled having conductors applied to the contact pads on the element and is packaged in an assembly for introduction to the exhaust stream of a combustion process. A large step-wise change in the resistance of the element takes place as a result of changes in oxygen content in the exhaust whereby one can determine if the exhaust is rich or lean for use in an engine management or combustion management systems for emissions control. A circuit is proposed to convert the change in resistance to a voltage signal to be used for control algorithms in engine or combustion control. Utilizing multiple units of the device for individual cylinder control of multi-cylinder engines is described. A method of using one embodiment of the invention for use as a safety switch is also revealed.
摘要翻译：提供了一种制造次微型“微芯片”氧传感器的方法，其中将多个传感器元件施加到由加热器图案组成的介电陶瓷基板，随后是介电层。然后将相互啮合的电极施加在加热器图案/电介质层的上方或衬底的相对侧上。相互啮合电极之间的空间填充有被多孔保护层覆盖的n型或p型高温半导体。在分割（切割）之后，传感器元件被组装成具有施加到元件上的接触焊盘的导体，并且被封装在用于引入燃烧过程的排气流的组件中。由于排气中的氧含量变化，可以确定元件的阻力发生巨大的逐步变化，从而人们可以确定排气是富还是用于发动机管理或用于排放控制的燃烧管理系统。提出一种电路来将电阻变化转换成用于发动机或燃烧控制中的控制算法的电压信号。描述了利用多个单元的装置用于多缸发动机的单独气缸控制。还揭示了使用本发明的一个实施例用作安全开关的方法。

摘要： A green ceramic core or other article at elevated temperature is placed between a complaint member and a relatively rigid setter while the green core or article cools to a lower temperature. The compliant member can comprise a fluid pressurized compliant bladder or a compliant, non-rigid setter or facing layer thereon for contacting a side of the green core or article.
