Title: Dc feeding circuit trouble detector
Inventor: IDENO ICHIRO
IPC: B60M3/00
Filed: 1989-08-02
Abstract: PURPOSE:To enable any troubles in a DC feeding circuit to be deteced from a power station by utilizing the DC side high-harmoics generated by a rectifier to detect the trouble with a phase angle obtained from the DC side high- harmonic voltage and high-harmonic current. CONSTITUTION:DC electric power converted by a rectifier 4 is supplied to an electric car 10 through a rail 8 and electric car line 9. The rail 8 and electric car line 9 of a feeding circuit comprise a conductor resistance component and inductance component determined by the geometric arrangement of the feeding circuit. These components are proportional to the length of the feeding circuit. The DC side high-harmonic degree n generated in the electric power conversion of the rectifier 4 is n=6m(m=1, 2...) in the rectifier 4 of 6 pulses and a reactor 7 is provided in series to a DC filter 6 for the sake of a measure against commu nicating induction, while a portion of current overlaps the DC current when current is supplied to the electric car 10 through the electric car line 9. A judge ment output section 3 calculates a phase angle of the sixth harmonic wave current and voltage flowing most largely to the line 9 from high-harmonic current and voltage extracted from a current converter 2 and voltage converter 1 to judge troubles from the calculated value and generates the output.

Title: Optical modulator
Inventor: INOUE MASAHIRO
IPC: H04B10/61
Filed: 1983-10-27
Abstract: PURPOSE:To obtain an optical modulator suitable for high-speed modulation by providing an optical modulating plate, which is arranged around a light emission source and has the transmittance changed in accordance with the value of an applied voltage or current to modulate the light radiated from the light emission source, to radiate optical modulated signals without controlling directly the current of the light emission source. CONSTITUTION:A light emission source 1 is always held in a stable light emission state, and a signal generated from a transmission side terminal device 6 is modulated by a modulating circuit 7, and this modulated signal is inputted to a driving circuit 10. Since the voltage or the current applied to an optical modulating plate 9 is changed by the driving circuit 10, the transmittance of the optical modulating plate 9 is changed. As the result, the light radiated from the light emission source 1 is radiated to the space as an optical modulated signal which is modulated in accordance with the transmittance of the optical modulating plate 9. This optical modulated signal is a signal modulated in accordance with the signal generated from the transmission-side terminal device 6. The optical modulated signal is converted to a current by a photodetector 12 and is received through a light receiving circuit 12 and a demodulating circuit 14 by a reception- side terminal device 15, and thus, optical space communication is performed.
