Title: Variable frequency light source
Inventor: AKIYAMA KOJI
IPC: H01S5/06
Filed: 1988-04-28
Abstract: PURPOSE:To accurately measure an output light frequency by performing the calibration of a Fabry-Perot interferometer, the adjustment of an output laser light, and the measurement of spectral characteristics of the interferometer by use of three lasers respectively. CONSTITUTION:First, a contact C of a switch 32 is connected to a contact B, and a Fabry-Perot interferometer is calibrated on the basis of an output from a laser 20. Then, the contact c of the switch 32 is connected to a contact A. An optical detector 26 detects a beat of the output lights from the laser 20 and a laser 35, and detects the number of the beats by a counter 33. In this state, as the temperature of a constant temperature chamber 37 is varied by a temperature control means 38, the frequency of the output beam from a laser 36 can be fixed to that of a peak of a light passing through the interferometer 4. Additionally, the frequencies of the output lights from the lasers 20, 35 are detected by the optical detector 26 on whether or not they are coincident with each other, and at the same time the number of times of the fluctuations of an output from the detector 26 is measured by the counter 33 until the frequencies of the lasers 35, 36 are coincident. The frequency of the output light can accurately be measured on the basis of the just mentioned number of time, the characteristics of the interferometer 4 and the frequency of the laser 20.

Title: Open-phase detection circuit for three-phase power supply
Inventor: ONO AKIHISA
IPC: G01R19/155
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To obtain an open-phase detection circuit by which not only the on-off operation of an AC input voltage but also an open phase in only one phase out of three phases can be detected by a method, wherein output signals of a plurality of AC-voltage detection circuits are combined. SOLUTION: Photocouplers 1, 2 are AC-voltage detection circuits which output a logic signal which is turned on at a time when the absolute value of an AC input voltage as viewed from a pseudoneutral point becomes a fixed value or higher. A CPU 4 is a discrmination means which discriminates the on-operation or the off- operation of the AC input voltage on the basis of the logic level of output signals (a), (b). Then, when three phases are normal, both the output signals (a), (b) are square- wave outputs at H→L and L→H. When an R-phase is an open phase, the signal (a) is at solid H, and the signal (b) is a square-wave output at H→L and L→H. In addition, when an S-phase is an open phase, the signal (b) is at solid H, and the signal (a) is a square-wave output at H→L and L→H.  When a T-phase is an open phase, the signal (b) is at solid H, and the signal (a) is a square-wave output at H→L and L→H. When a power supply is cut off, the signals (a), (b) are both at solid H. That is to say, when one out of the signals (a), (b) is at solid H, it can be judged that an open-phase state exists in the three phases.

Title: Transmission power control circuit
Inventor: TAKENAGA KOTARO
IPC: H04B1/04
Filed: 1990-04-25
Abstract: PURPOSE:To quicken the reply speed in response to a transmission input subjected to amplitude modulation and to reduce distortion by a modulation wave component by obtaining a control voltage of a gain variable circuit in response to a voltage of a voice signal obtained by detecting a high frequency input signal. CONSTITUTION:A gain of a gain variable circuit 1 is controlled by using a control voltage from a detection voltage detected and amplified by a transmission output so as to keep the transmission output constant. A COMP 11 compares a DC voltage obtained from the voice signal with a prescribed voltage and outputs a signal operating a sample-and-hold circuit 12 when the input voltage is a prescribed voltage or over. When a high frequency input is subject to amplitude modulation with a prescribed modulation degree or over, the sample-and-hold circuit 12 is operated to hold a just preceding control voltage. Since the control voltage is in holding, stable power is amplified without causing distortion due to the modulation wave component. When the high frequency input is amplitude-modulated at a prescribed modulation degree or below, the sample-and-hold circuit 12 is not active and the transmission power is controlled.
