摘要： Provided is a manufacturing method of a metal oxide semiconductor material for gas sensors by which an oxide precursor and noble metal colloid particles will not readily cohere in the manufacturing process. The manufacturing process implements a precursor solution synthesis step 1 of synthesizing an oxide precursor solution in which an oxide precursor is dispersed, a pH adjustment step 3 of adjusting the pH of the oxide precursor solution, a precursor-colloid dispersion preparation step 5 of preparing an oxide precursor-noble metal colloid dispersion in which the oxide precursor and the noble metal colloid are dispersed substantially uniformly, a purifying step 7 of purifying the oxide precursor-noble metal colloid dispersion to obtain a purified oxide precursor noble metal colloid dispersion, and a freeze-drying step 11 of freeze-drying an precipitate of the purified oxide precursor-noble metal colloid dispersion.

摘要： Provided herein is a vibration-type angular velocity sensor capable of improving detection precision of angular velocities around the Z axis and preventing detection precision of angular velocities around the X and Y axes from deteriorating. A weight 3 is columnar or conic. The outline of an outer peripheral portion of a diaphragm 1 has such shape that a straight portion ST is formed at each of four corner portions of a square. Four vibration exciting electrodes 11 are respectively located in four regions partitioned by a first imaginary line L1 and a second imaginary line L2. Four angular velocity sensing electrodes 13 are respectively located in four regions partitioned by a first imaginary diagonal line CL1 and a second imaginary diagonal line Cl2.
