Title: Pressure transducer
Inventor: YAMAMOTO YOSHIMI
IPC: G01L9/04
Filed: 1978-05-24
Abstract: PURPOSE: To make the construction simple and prevent measurement errors occuring in the thermal stress from the body by mounting a strain detecting element having a hermetic space in its inside not directly to the pressure transducer body but through a strain detecting element fixing member.  
     CONSTITUTION: Liquid pressure is exerted to a seal diaphragm 4 and is transmitted to a diaphragm part 50 through sealing liquid 8. The fluid pressure is then measured by the strain generated in the diaphragm part 50 owing to the difference between this fluid pressure and the atmospheric pressure in the hermetic space 54 of the strain detecting element. This enables the construction of the pressure transducer simple. In addition, the strain detecting element composed of silicon is mounted not directly to the body but through a strain detecting element fixing member 61 composed of alumina ceramics and therefore the production of measurement errors occuring in the thermal stress from the body may be prevented.

Abstract: PURPOSE:To obtain a miniature pattern by easily forming a desired pattern on two- layer film having different etching properties to enable use of a high temperature heat resistant material to allow evaporation, CVD and sputtering at high temperature with the pattern. CONSTITUTION:On a substrate 1 are provided a film 5 to be etched fast and a film 6 to be etched slowly on the film 5, and a resist 2 thereon to form a pattern inverted from a desired pattern on the film 6. With the resist 2 as a mask the film 6 is etched. When they are so etched at an etching speed as to be faster than the etching speed of the film 5 and slower than the etching speed of the film 6, the film 5 becomes inverted tapered shape. The resist 2 is then removed, and desired film 3 is evaported or treated by a CVD or a sputtering process. Thereafter, the film 5 is selectively etched to remove the films 6 and 3 on the film 5. According to this process, it can eliminate the separation, deformation and other disadvantages of the resist film, and adhere the film 3 at high temperature. Therefore, it can expand the range of application with a lift-off so as to easily form a miniature pattern.
