Title: Variable frequency light source
Inventor: AKIYAMA KOJI
IPC: H01S5/062
Filed: 1988-06-27
Abstract: PURPOSE:To assure a variable frequency light source excellent in frequency accuracy and long-time stability with a simplified structure by changing an oscillation frequency of a semiconductor laser by changing a frequency of an oscillator. CONSTITUTION:A switch 14 is shifted from the side (a) to the side (b) when the oscillation frequency of a semiconductor laser makes coincidence with one frequency at a point P among peaks of transmission characteristics of a Fabry-Perrot interferometer 6. Modulation frequency f1 is here assumed f1L. An output from an optical detector 9 is subjected to synchronous detection with a frequency f1 signal in a synchronous rectifier circuit 131. The output is proportional to a frequency difference between FM sub-carriers 22, 23 and the transmission peak through the Fabry-Perrot interferometer 6. Accordingly, with such a difference, a control section 132 controls an injection current into the semiconductor laser 1 such that said difference is zero. Hereby, the emission frequency of the semiconductor laser 1 is changed and the transmission peak of the Fabry-Perrot interferometer 6 is forced to follow the just- mentioned change of the emission frequency by first control means 10. Thus, FSR makes coincidence with the modulation frequency f1. In the above operation, the number (m) of modes of the Fabry-Perrot interferometer 6 is evaluated according to the formula I and the laser oscillation frequency f0 is continuously changed according to the formula II by changing f1.

Title: Water meter
Inventor: HIGUCHI TAKASHI
IPC: G01F1/58
Filed: 1995-06-26
Abstract: PURPOSE: To obtain a water meter by which a metered value during a power failure is estimated with high reliability by a method wherein the electrified time in which a power supply is turned on is recorded and the recorded electrified time is read out in the inspection of a meter in a metering operation. CONSTITUTION: When an external power supply is turned on so as to raise a power-supply voltage, a voltage detection circuit 9 releases a reset signal, and a main program in a CPU 6 is started. When the main program is started, the electrified time and the integrated time at a time when a power supply has been cut off last time are stored in a nonvolatile memory 7. They are read out so as to be set in a timer 8. After the timer 8 has been started, a steady state is set. The electrified time which has been set in the timer 8 is continued to be converted until the CPU 6 is stopped after the timer 8 has been started. When the external power supply is cut off so as to drop the power- supply voltage, the circuit 9 outputs an NMI signal, and an NMI program in the CPU 6 is started.  The NMI program reads out the electrified time and the integrated time up to that point of time from the timer 8 so as to be held in the memory 7.
