Title: Lighting device for electric discharge lamp
Inventor: OKAMOTO FUTOSHI
IPC: H05B41/42
Filed: 1987-12-23
Abstract: PURPOSE:To prevent a fluctuation in detected current due to the fluctuation of filament current by connecting a secondary winding of polarity reversed from a primary winding and using the tertiary winding of a current transformer as a lamp current detection winding. CONSTITUTION:The primary winding n1 of a current transformer T1 is connected to the power supply side of filaments f1 and f2 of an electric discharge lamp A, and the secondary winding n2 of the current transformer T1 is connected to the non-power supply side of the aforesaid filaments f1 and f2. In this case, the first and second windings n1 and n2 are applied to have polarity reversed from each other. And the tertiary winding n3 of the current transformer T1 is connected between the base emitters of a dimmer transistor Q3 via an impedance Z1, a diode D3 and a dimmer switch SW1. According to the aforesaid construction, only the component of lamp current I1 can be fed to the dimmer transistor Q3 and the components of filament current I2 offset each other, thereby not being fed to the dimmer transistor Q3. Consequently, it becomes possible to make a dimmer control without undergoing any influence by the filament current I2.

Filed: 1988-12-24
Abstract: PURPOSE:To make a tapping difficult by using a phase distortion generator so as to give distortion to a digital signal at a transmission side and using a phase distortion equalizer correcting the distortion at a reception side. CONSTITUTION:A voice signal inputted from a microphone 1 is converted into a digital signal by an A/D converter 2. Then in order to be a spectrum within a radio frequency allocation, a phase distortion generator 10 gives a phase distortion through a filter 3 eliminating a high frequency component. The signal is modulated, amplified by a transmitter 4 and the result is radiated from a transmission antenna 5. A reception antenna 6 at the reception side receives the radio wave, demodulated in a receiver 7, and a phase distortion equalizer 11 equalizes waveform distortion generated by the phase distortion generator 10. Then a D/A converter 8 decodes the signal into the original voice signal and the result is outputted from a speaker 9. The tapping is made difficult by adding the phase distortion generator 10 and the phase distortion equalizer 11 to a conventional digital communication equipment in such a manner.
