    摘要： A semiconductor pressure sensor is not influenced by a charged object in a fluid to be measured or an electric field from the outside, so satisfactory sensitivity and accuracy can be ensured. The semiconductor pressure sensor is provided with a diaphragm 4 that responds to the pressure of the fluid to be measured. The diaphragm includes a silicon substrate with piezoresistive elements, which together constitute a bridge circuit, being embedded therein, and a shield film for electromagnetic shielding formed on a surface of the silicon substrate at a side thereof at which the fluid to be measured is in contact with the silicon substrate. The shield film is electrically connected to the silicon substrate so as to have the same potential as that of the silicon substrate.

    摘要： A semiconductor angular velocity determining device includes a piezoelectric substance, a first substrate 21 disposed on the piezoelectric substance, a detector main body disposed on the first substrate 21 and a second substrate for holding the detector main body in cooperation with the first substrate 21 therebetween. The detector main body includes an oscillator 27 having a linear beam portion 26 with a one end 26a of the beam portion 26 being directly fixed to the first substrate 21. Further, the other end 26b of the beam portion 26 draws an elliptical locus in response to the combined force resulting from a force from the piezoelectric substance for producing oscillation along the plane of the first substrate 21 and a Coriolis force acting on the first substrate 21 in a perpendicular direction. With this arrangement, there can be obtained the semiconductor angular velocity determining device capable of improving a determining sensitivity and a determining accuracy.

    摘要： An angular velocity sensor device that is produced in a simplified manufacturing process and at a reduced manufacturing cost. The angular velocity sensor device includes a first beam which extends along the surface of the substrate and to which a vibration driving source imparts a vibration in an X-axis direction along the surface of the substrate, and a second beam which follows an elliptical trajectory along the surface of the substrate in response to the resultant force of the force in the X-axis direction and a Coriolis force acting in an Y-axis direction perpendicular to the X-axis direction along the surface of the substrate.

    摘要： Disclosed is a toner obtained by coating surfaces of core particles including at least a binder resin having a carboxyl group and a coloring agent with successive coatings of a water-soluble crosslinking agent capable of crosslinking with a carboxyl group and a water-soluble polymer having a carboxyl group, which have been successively applied on the core particles and crosslinked with each other. The thus-formed toner is provided with a good harmony of favorable fixability represented by a low lowest fixable temperature and favorable storage stability represented by little aggregation after standing at 50° C. for 8 hours.
