摘要: A semiconductor pressure sensor includes a semiconductor substrate having a diaphragm for receiving pressure and a bridge circuit for detecting a distortion of the diaphragm corresponding to the pressure. The bridge circuit includes a pair of first gauge resistors and a pair of second gauge resistors. The first gauge resistors are disposed on a center of the diaphragm, and the second gauge resistors are disposed on a periphery of the diaphragm. Each first gauge resistor has a first resistance, which is larger than a second resistance of each second gauge resistor. The TNO property of the sensor is improved, so that the sensor has high detection accuracy.

摘要: In a semiconductor dynamic quantity sensor, a mass serving as a weight portion for detecting application of a dynamic quantity is divided into three masses (301, 302, 303) in series. The masses (301, 302, 303) thus divided are connected to one another by connecting beams (CB1, CB2, CB3, CB4). The masses (301, 302, 303) located at both the end portions are supported through beams (B1, B2, B3, B4) by a semiconductor substrate (1) so as to be allowed to be displaced in the direction orthogonal to the connection direction of the masses. The center mass (302) connected to the masses (301, 302, 303) through the connecting beams (CB1, CB2, CB3, CB4) is allowed to be displaced only in the connecting direction of the masses by the connecting beams (CB1, CB2, CB3, CB4).

摘要: A coating machine is capable of reducing VOC and CO2 by atomizing a paint to increase depositing efficiency without lowering production efficiency and the rotary atomizing head of the coating machine. The coating machine includes the rotary atomizing head in which a paint chamber receiving the supply of paint is formed on the rear side thereof. A plurality of rims formed in a roughly truncated conical shape for extending the paint flowing out of the paint chamber by a centrifugal force and atomizing the paint at the tip thereof are fitted in the rotary atomizing head overlappingly at specific clearances. The clearances are opened to the peripheral surface part of the paint chamber. Accordingly, VOC and CO2 can be reduced by reducing the total jetted amount of paint to enable the atomization of the paint at low rotating speeds so as the increase the deposit efficiency.
