摘要： An actuator (A) includes a body (10) in which a plurality of chambers or bores (34) are defined. The bores are interconnected at an inner end by an elongated passage (30). A heater element (32) extends along the elongated passage. The elongated passage and the inner portion of each chamber or bore are filled with a polymeric material which expands and flows on heating, preferably undergoing a solid to liquid phase change. Extensible members (12), such as pistons, diaphragms, bellows, or the like, are mounted in the bores or wells. When the heater heats the polymeric material causing it to expand and flow, the extensible elements (12) extend under high force with limited travel. In one embodiment, the extension of the extensible members moves a thrust bearing (B) causing frictionally engageable plates (18, 22) of a friction member assembly (C) to engage.

摘要： A pressure transducer utilizes a diaphragm made, for example, of ceramic or the like having upper and lower surfaces. One surface of the diaphragm receives an elongated thick film resistor. Circuitry is connected to the resistor for measuring any changes in resistance due to strains or forces applied to the resistor. Pressures applied perpendicularly to the longitudinal direction of elongation of the resistor produces high outputs in the form of changes in resistance which can be used to calculate strains in the longitudinal and transverse directions as well.
摘要翻译：压力传感器利用例如具有上表面和下表面的陶瓷等制成的隔膜。隔膜的一个表面接收细长的厚膜电阻。电路连接到电阻器，用于测量由于施加到电阻器的应力或力引起的电阻变化。垂直于电阻器长度方向施加的压力以电阻变化的形式产生高输出，其可用于计算纵向和横向上的应变。
