Title: Driving circuit for semiconductor laser
Inventor: SATOU KENICHI
IPC: H04B10/2507
Filed: 1981-01-31
Abstract: PURPOSE:To reduce semiconductor laser coherence by a method wherein a transistor is added to a driving circuit and a semiconductor laser is modulated by a signal composed of a modulating signal and a high frequency signal. CONSTITUTION:The collectors of two transistors (TR)6 and TR9 are combinedly connected to a semiconductor laser 1. The TR6 base is supplied with a high frequency signal of 50MHz-20GHz from a high frequency input terminal 7. The TR9 base is supplied with a transmitted signal from the signal input terminal 2. The combined TR6 and TR9 collectors are then connected to TR8 supplying a DC bias current to the laser 1. A high frequency pulse is imposed on the current wave running in the laser 1 so that the laser 1 oscillation spectrum is multiplied, laser coherence is reduced, and therefore laser coherence caused deterioration of the signal wave form is reduced.

Title: Magnetic field sensor device
Inventor: MIYAKE RYOHEI
IPC: G01R33/032
Filed: 1988-01-22
Abstract: PURPOSE:To prevent the light power of a light signal which passes through a sensor part from decreasing even if the ambient temperature of the sensor part rises by controlling the quantity of light of a light source so that the DC voltage signal outputted by a photodetector becomes constant. CONSTITUTION:A Faraday element 11 which uses bismuth substitute rare earth iron garnet crystal is interposed between the light source 2 and photodetector 4 to constitute the sensor device which detects a magnetic field applied to the Faraday element 11. The DC voltage signal outputted by an amplifier 5 is fed back to a power source 1 and the quantity of light of the light source 2 is so controlled that the DC signal outputted by the photodetector 4 becomes constant. Consequently, the light power of the light signal passing through the sensor part 3 is held constant regardless of the ambient temperature of the sensor part 3. Thus, the S/N ratio is increased and the magnetic field of an AC component is measured.

Abstract: PURPOSE:To make it possible to control a current conduction angle in correspondence with applications and to improve efficiency, by performing the control so that current conduction through stator windings is made in one direction by the detected output of a counter electromotive force, and omitting special provision of a position detecting mechanism. CONSTITUTION:In the vicinity of time T1, when the counter electromotive voltages 11-2a and 11-3a are lower than 11-1a and the counter electromotive voltage is generated in the stator winding 11-1 in the direction of an arrow C, the potential at a terminal 19 becomes higher than that of a terminal 18. Then a transistor 25 is turned ON by the detected signal of the counter electromotive voltage from an operation amplifier 22,  which is amplified to the more positive direction than the voltage at a reference voltage terminal 29-3. Therefore a current is conducted through a bridge circuit including the stator winding 11-1. When a rotor is rotated and the counter electromotive voltage is generated in the stator winding 11-2 in the direction of an arrow D (in the vicinity of time T3), a transistor 26 is turned ON by the output of a counter electromotive voltage detecting circuit 12-2 as described before, and a current is conducted through a bridge circuit including the stator winding 11-2.

Abstract: PURPOSE: To remove high-frequency components from a reference signal and eliminate its lag due to a filter, by inserting AC filters of equal characteristics into a phase reference circuit and a feedback circuit, respectively.  
     CONSTITUTION: The output e2 of a phase comparator (PHD) 1, which takes the exclusive OR of the rectangular-wave phase reference signal e0 with an output signal e7, is averaged by a loop filter 2 and then supplied to a voltage control oscillator (VCO) 3.
