    摘要： The present invention is directed to a capacitive differential pressure detector comprising a diaphragm disposed between two electrodes. In a first embodiment, each of the electrodes comprises two conductive plates with an insulator disposed therebetween. Step-like portions are formed in the conductive plate nearest the diaphragm. In a second embodiment, the plate nearest the diaphragm is insulative with a conductive film formed thereon. In a third embodiment, at least one groove is formed in the plate nearest the diaphragm. The groove is formed in a surface of the plate which faces the diaphragm. The groove also intersects a pressure guide hole. In a fourth embodiment, a substrate is disposed on a surface of the plate farthest from said diaphragm. In a fifth embodiment, an insulating layer has the same coefficient of thermal expansion as the conductive plates. In a sixth embodiment, the diaphragm is etched in order to form a circular flexible part, a centrally disposed displacing part, and a bonding part.

    摘要翻译： 本发明涉及一种电容差压检测器，其包括设置在两个电极之间的隔膜。 在第一实施例中，每个电极包括两个导电板，绝缘体位于它们之间。 在最靠近隔膜的导电板中形成阶梯状部分。 在第二实施例中，最靠近隔膜的板是绝缘的，其上形成有导电膜。 在第三实施例中，在最靠近隔膜的板中形成至少一个凹槽。 凹槽形成在板的面向隔膜的表面中。 凹槽还与压力导向孔相交。 在第四实施例中，基板设置在距所述隔膜最远的板的表面上。 在第五实施例中，绝缘层具有与导电板相同的热膨胀系数。 在第六实施例中，为了形成圆形柔性部分，中心设置的位移部分和接合部分，蚀刻隔膜。

    摘要： An X-ray photography cassette incorporating an automatic peeler for removing the film from the cassette. The cassette includes a frame and a front plate mounted on the frame and with a rear cover coupled to the frame through hinges. Intensifying screens are positioned adjacent the front and rear cover. A peeling member is elastically coupled to one of the frame or rear cover and extending into a recess or cut-out portion formed in the intensifying screen. A space is provided between the peeling member and the other intensifying screen for receiving the film.
