摘要： A vibrating gyroscope includes supporting members which are fixed in the vicinity of two node axes n1 and n2 of a bar-shaped vibrator. The supporting members corresponding to node axis n1 extend from the locations at which they are fixed to the vibrator in the widthwise direction of the vibrator, and also include bending portions and a proximity portion. The bending portions bend toward node axis n1. At the proximity portion, the supporting members are in close proximity with each other with a gap therebetween in the vicinity of node axis n1.

摘要： A vibration gyroscope which is capable of accurately detecting a rotational angular velocity regardless of environmental changes or changes in vibrator characteristics includes a vibrator formed of a vibration element, and first and second piezoelectric elements for detection and a third piezoelectric element for driving. Output currents of the first and second piezoelectric elements are converted into voltages by I-V conversion circuits, or output voltages of the first and second piezoelectric elements are detected by voltage detection circuits, and then the voltages are added together by an adder circuit. An output signal of the adder circuit is monitored by a monitor circuit. On the basis of this result, the voltage or the phase of a drive signal fed from an oscillation circuit to the third piezoelectric element is controlled. The output signals of the I-V conversion circuits or the output signals of the voltage detection circuits are formed into a DC signal corresponding to a rotational angular velocity via a differential amplifier circuit, a synchronization detection circuit, a smoothing circuit, and an amplifier circuit.

摘要： A body fluid excretion volume measurement apparatus for medical application. The apparatus stores body fluid excreted from patients in a body fluid storage tank and measures the resistance value with a resistance sensor. The resistance value depends on the shape of the body fluid storage tank, and if the tank is columnar, the resistance value is monotonically increasing with respect to the depth of body fluid. The output of the resistance sensor is processed by a measurement part and electric measurement of the body fluid volume stored in the body fluid storage tank is performed automatically.
