The structure is such that the crystal resonator is arranged on one principal plane of the ceramic substrate, and the chip resistor and the temperature sensitive element are arranged on the other principal plane of the ceramic substrate, and the other principal plane of the ceramic substrate is positioned facing one principal plane of the circuit board, and heat conductive resin is interposed between the chip resistor and the circuit board. A surface mounted crystal oscillator of constant temperature type in which miniaturization is advanced, and the structure is simplified, is provided.

    摘要： A diagnosing operation controlling portion compares the magnitude of change of a control instruction value that controls the dislocation of a valve stem to a reference value that has been set in advance, and stops the malfunction evaluation operation in a diagnosing portion if the magnitude of change per unit time in the control instruction value exceeds a reference value. If the magnitude of change per unit time in the control instruction value exceeds the reference value, then the evaluation may be the same as for a case wherein a stick-slip has occurred, even if the operation is functioning properly. In contrast, it is possible to prevent incorrect stick-slip evaluations by stopping the operation of the diagnosing portion when the magnitude of change per unit time in the control instruction value exceeds a reference value.

    摘要： A PLL circuit is provided capable of reducing phase noise and facilitating design. In the PLL circuit, a PLL receives a reference frequency and an output from a VC-TCXO, performs a lock operation. In a lock state, a selector selects an output of a first divider that divides the reference frequency. When PLL detects input of reference frequency being lost or an unlock state, the PLL outputs an alarm signal to the selector. When receiving the alarm signal from the PLL, the selector switches from the output of the first divider to an output of a second divider that frequency-divides an output of the VC-TCXO, and outputs the same. Then, a PLL receives an output of the selector and an output of a VCXO and performs a lock operation.
