摘要： A silicon or quartz wafer for forming a SAW device is the subject of grinding and lapping operation to form its basic shape. The opposing surfaces, as well as the edges extending therebetween, are the polished to reduce the number and size of defects in the surfaces. Metal is deposited onto one of the opposing surfaces which, in use, will be under compression, to form electronic components thereon, and a multi-metallic coating having an outer layer formed of gold is applied to the other surface to form a solder pad by means of which the wafer may be fastened to a shaft or the like by soldering. Martensitic stainless steel is used as a mount, saddle or housing for the SAW substrate.

摘要： A device for measuring torsional distortion of a body comprises first and second clip portions each having a central part and two legs depending from the central part, each leg having adjacent the free end thereof a groove or projection for engaging a respective projection or groove (14) provided in the body (16) to mount the clip portion the body rotationally fastened therewith. A bridge interconnects the clip portion. The bridge is less stiff than the clip portions whereby relative rotational displacement of the clip portions caused by torsional distortion of the body will cause proportional deflection of the bridge. Means, for example a SAW device (15), are provided for measuring the deflection of the bridge to provide an indication of the torsional distortion which produces the deflection of the bridge. Also (20) for the interior all of a hollow body.

摘要： A pressure monitor has a base and a lid secured to the base to define a substantially fluid tight chamber. At least part of the lid is flexible and forms a diaphragm which deflects responsive to changes in fluid pressure surrounding the monitor. A projection provided on the diaphragm transmits movement thereof to a distortable substrate located within the chamber. A first SAW device is mounted on the distortable substrate, and at least a second and third SAW device are mounted within the chamber. The second SAW device carried on a reference substrate section has its direction of propagation inclined at an angle to the direction of propagation of at least one of the first and third SAW devices. This way movement of the diaphragm induced by a change in pressure in the zone surrounding the monitor results in distortion of the distortable substrate, which is measurable by the SAW device mounted thereon, without distorting said reference substrate section.
