摘要: A low vapor-pressure material feeding apparatus comprises a bubbler (4, 5), accommodating a low vapor-pressure material (6) therein, for bubbling the low vapor-pressure material (6) with an inert gas fed from an inert gas container (3). A bifurcated gas feeding passage (51, 8) is provided between the gas container (3) and a vacuum chamber (50). One branch passage directly introduces an inert gas into the vacuum chamber (50), and the other branch passage introduces an inert gas into the bubbler (4, 5). A gas mixture of a vaporized low vapor-pressure material (6) and the inert gas, is supplied from the bubbler (4, 5) to a vacuum chamber (50). A gas flow meter (7) detects a flow amount of the gas mixture. On a basis of a gas flow amount detected by the gas flow meter (7), an inert gas controller (10) adjusts a feeding amount of inert gas so that a total amount of an inert gas introduced directly into said vacuum chamber (50) and an inert gas introduced into the bubbler (4, 5) is kept at a constant value.

摘要: A small and highly sensitive capacitance type pressure sensor is obtained by filling an alkali halide material such as KBr into a through-hole, forming a conductive thin film on the surface, and dissolving and removing the alkali halide material. An insulating plate disposed with a through-hole in the thickness direction is filled with a molten alkali halide material such as KBr. After forming a conductive thin film on the surface of the alkali halide material filled into the through-hole and the vicinity thereof, the alkali halide material is dissolved by water and removed. In this way, a diaphragm is made of the through-hole and the conductive thin film. A curve of the diaphragm caused by a pressure difference between the both faces of the conductive thin film is detected as a capacitance change between the conductive thin film and the electrode layer.

摘要: A thin film sensor element includes a sensor holding substrate having an opening part and a multilayer film adhered thereon at least consisting of an electrode film A, an electrode film B having (100) plane orientation, and a piezoelectic dielectric oxide film present between the electrode film A and the electrode film B. As a result, a thin film sensor element which is small, light, highly accurate, and inexpensive can be attained which can be used for an acceleration sensor element and a pyroelectric infrared sensor element. On the surface of a flat plate KBr substrate, a rock-salt crystal structure oxide of a conductive NiO is formed by a plasma MOCVD method whose vertical direction is crystal-oriented to direction against the substrate surface. By means of a sputtering method, a PZT film is formed by an epitaxial growth on that surface, and a Ni-Cr electrode film is formed thereon. Next, the multilayer film structure is reversed and adhered to a sensor substrate having an opening part with an adhesive. After a connection electrode is connected, the whole structure is washed with water, thereby removing the KBr substrate.
