Abstract: A flexible substrate (110) having flexibility and a fixed substrate (120) disposed so as to oppose it are supported at their peripheral portions by a sensor casing (140). An oscillator (130) is fixed on the lower surface of the flexible substrate. Five lower electrode layers (F1 to F5: F1 and F2 are disposed at front and back of F5) are formed on the upper surface of the flexible substrate. Five upper electrode layers (E1 to E5) are formed on the lower surface of the fixed substrate so as to oppose the lower electrodes. In the case of detecting an angular velocity ?x about the X-axis, an a.c. voltage is applied across a predetermined pair of opposite electrode layers (E5, F5) to allow the oscillator to undergo oscillation Uz in the Z-axis direction. Thus, a Coriolis force Fy proportional to the angular velocity ?x is applied to the oscillator in the Y-axis. By this Coriolis force Fy, the oscillator is caused to undergo displacement in the Y-axis direction.

Since the buffer chamber collects molecules, which permeate through a bonding interface between the two wafers, a raise in pressure of the reference chamber can be avoided. The sensor is therefore more resistant to pressure equalisation between the pressure chamber and the pressure of the surroundings, i.e. the sensed pressure and repetitive recalibration of the sensor can be avoided.

Abstract: A wide range continuous diluter for diluting gases that contain small particles to allow subsequent measurement of the diluted gases with an instrument is provided. A dilution gas inlet receives a dilution gas, and a sample gas inlet receives a sample gas. A flow meter measures the sample gas flow rate. A mixer receives and mixes the dilution gas and the sample gas at a dilution ratio. An instrument flow outlet provides a well-defined flow into the instrument from the mixture flow. A make-up gas inlet is arranged to provide make-up gas into the mixture flow at a controlled rate. Because the dilution gas flows at a controlled rate and the mixture flows at a controlled rate, changing the flow rate of the make-up gas causes a responsive change in the sample gas flow rate, thereby allowing continuous adjustment and control of the dilution ratio when desired.

The transmission brake is further provided with disengagement, given consideration of lead time, before the calculated disengagement point in time.
