Abstract: PROBLEM TO BE SOLVED: To improve rangeability in detecting a pressure corresponding to a shift of a pressure-receiving diaphragm, by providing an elastic thin film of a shell structure between the pressure-receiving diaphragm deformed in accordance with a pressure and a substrate supporting the diaphragm. SOLUTION: An absolute pressure sensor of, e.g. a capacitive type has a pressure-receiving diaphragm 2 formed of polysilicon or the like on a substrate 1, and detects a change of a capacitance generated at a gap 6 between the substrate 1 and pressure-receiving diaphragm 2. An insulating film 3 forming a plurality of elastic rotary plane shells 3a, for example, in lattice is united to a rear face 2A of the pressure-receiving diaphragm 2. A shift in a Z direction of the pressure-receiving diaphragm 2 is elastically controlled by a reaction from the shells 3a. A sufficient linearity in a high pressure range is accordingly maintained and moreover, sensitivity without any trouble is realized even in a low pressure range. If the rotary plane shells of different radii are arranged concentrically or in the like manner, strength to an excess of range is improved further.  The pressure sensor can be constituted also as a differential pressure meter.

Title: High purity dielectric thin film
Inventor: MATSUURA MASAYA
IPC: C01G35/00
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce leakage current so as to improve electric characteristics by employing a Sr-Bi-Ta-O series high purity dielectric thin film with an alkali metal content less than a specific value. SOLUTION: A thin film with alkali metal content less than 1ppm and its composition is (SrXBi1- X)Bi2 Td2 OY is used. However, 0<x<1, is applicable and Y is the total of oxygen atoms belonging to respective kinds of metal. If the alkali metal content is less than 1ppm, preferably not more than 0.1ppm leakage current can be reduced to much extent, since the deposition quantity of impurity in a particle filled bringing the cause of leakage current generation is quite small even in the case of dielectric thin film where crystalline property is improved by heat treatment. This thin film can be obtained by a method of applying organic solvent solution of organic metal compound on the substrate and burning it, or by using a target obtained by forming metal oxide and burning it so as to make sputtering on the substrate and making a film and burning it.

Abstract: PROBLEM TO BE SOLVED: To reduce a circuit scale and power consumption by estimating an error through the use of the output of a first-order delay detection circuit extending over consecutive three time slots. SOLUTION: When ei , ei+1 are provided with the size of some degree with respect to a threshold value 45 but do not exceed the threshold value 45 and ei and ei+1 form the three conditions of reverse polarity, estimated error signal bar -ei , a bar ei+1 are detected to correct an error.
