摘要： In a frost and dew sensor composed of two thermosensitive resistors, a power source and an arithmetic circuit, frost or dew is detected from the change of a differential temperature between the two thermosensitive resistors as two different currents from the power source are supplied to the respective thermosensitive resistors. In an alternative form, the sensor has a single thermosensitive resistor, which is energized as two different currents are alternately supplied from the power source so that frost or dew is detected by comparison of the time-lags between the two outputs from the thermosensitive resistor.

摘要： In an angular velocity sensor for sensing angular velocities about two axes or an X-axis and a Y-axis which are perpendicular to each other, a frame-shaped oscillator (26) is disposed to the respective support portions (24) fixed on a substrate (22) through support beams (25) and a columnar electrode (33) is disposed in the oscillator (26) by being fixed to the substrate (22). X-axis displacement sensing units (31) are formed on the right and left sides of the oscillator (26) and Y-axis displacement sensing units (32) are formed to the forward and rearward sides thereof. When an oscillation drive signal is imposed between the oscillator (26) and the columnar electrode (33), an electrostatic attracting force is generated therebetween and the oscillator (26) is oscillated in a Z- axis direction. When an angular velocity ΩY is imposed about the Y-axis at this time, the oscillator (26) is displaced to the X-axis by an Coriolis force and the displacement can be sensed by the X-axis displacement sensing units (31), whereas when an angular velocity ΩX is imposed about the X-axis, the oscillator (26) is displaced to the Y-axis by an Coriolis force and the displacement can be sensed by the Y-axis displacement sensing units (32), so that the angular velocities about the two axes or the X-axis and the Y-axis can be sensed, respectively.
