摘要： Disclosed is a PLL oscillator circuit capable of examining an unlock state while being equipped with an auto retry function enabling automatic relock. In the PLL oscillator circuit, a MPU receives a lock detection signal from the PLL-IC that receives an external reference signal and an output signal from a VCXO and outputs a control voltage to the VCXO, sets data for unlock alarm test at the PLL-IC, the data turning a lock state into an unlock state, when determining an unlock state with the lock detection signal from the PLL-IC, outputs an unlock alarm output signal to the outside, determines whether the unlock state continues for a first time period, and when the unlock state continues for the first time period, executes retry to set data for relock at the PLL-IC.

摘要： In a communication system for communicating a plurality of frequency signals between a first apparatus 1 and a second apparatus 2 via a common cable 3, a level loss component of each of the frequency signals in the cable is effectively corrected. Both transmission-sided reference frequency signal level detecting means 41 and 43 of the first apparatus, and reception-sided reference frequency signal level detecting means 71 and 73 of the second apparatus detect a level of a frequency signal which constitutes a reference among frequency signals which are transmitted from the first apparatus to the second apparatus via the cable. In the first apparatus, out-of-reference frequency signal level control means 44 to 51, and 32 to 35 control levels of the frequency signals other than the frequency signal which constitutes the reference and is communicated between the first apparatus and the second apparatus via the cable based upon a compared result between results detected in the first apparatus and results detected in the second apparatus.

摘要： An object of the present invention is to provide a Langevin type quartz sensor which is high in measurement sensitivity, suppresses the influence of the surface tension of a sample solution during measurement, and enables an installed quartz resonator to stably oscillate. As a specific means to solve the problem, a quartz sensor including a housing area forming portion surrounding the upper space on one face side of the quartz resonator for forming a housing area of the sample solution; an opposing surface portion opposing to one surface side of the quartz resonator via the housing area and being larger than the area coming in contact with the sample solution in the quartz resonator; and a pouring opening formed in the outside area of the opposing surface portion and at a position higher than said opposing surface potion for pouring the sample solution into the housing area is composed and measurement is conducted in a standstill state where the sample solution is filled in the lower side of the opposing surface portion. Since stress due to the surface tension of the sample solution does not act in this state, the quartz resonator can oscillate with reliability. Therefore, the quartz sensor of the present invention can reduced the thickness of the quartz resonator, which realizes highly sensitive and highly accurate measurement.
