Title: Metal halide lamp
Inventor: FUKUDA KUNIKI
IPC: H01J61/54
Filed: 1984-07-11
Abstract: PURPOSE:To provide a metal halide lamp which can be surely lit, by housing an ultraviolet ray generator, which functions to irradiate ultraviolet rays upon a luminous tube, and a switch, which functions to turn on and off the generator, in an outer tube to reduce the start voltage of the lamp. CONSTITUTION:When power 9 is applied, an electrical current restricted by a current limiting resistor 5 flows through an electromagnet 4. At that time, a magnetic field proportional to the magnitude of the current acts to a reed switch 2. When the magnetic field has reached a working level for the reed switch 2, the switch is turned on so that an electrical current flows through a filament 3 which is an ultraviolet ray generator which functions to irradiate ultraviolet rays upon a luminous tube 1. As a result, filament 3 emits light. When the electrical current flowing through the electromagnet 4 has decreased and the magnetic field has weakened below the working level, the reed switch 2 is turned off so that the current flowing through the filament 3 is cut off. As a result, the filament stops emitting the light. The turning on and off of the filament in every cycle of the power 9 is thus repeated.

Title: Voice signal noise eliminating circuit
Inventor: MIURA KATSUNORI
IPC: G11B20/06
Filed: 1984-07-12
Abstract: PURPOSE:To attain adequate dropout detection by providing a pre-value holding means controlled by the 1st comparison circuit output and a mute means of the pre-value holding means output controlled by the 2nd comparator circuit output. CONSTITUTION:Since the time constant of an output (e) of the 2nd integration circuit 22 is large, the output is a form proportional to a reproduced output without being much affected by the presence of short dropout. Since an output of the 2nd integration circuit 22 is a reference voltage Vr1 of the 1st voltage comparator circuit 8, the dropout is detected relatively. Further, a reference voltage Vr2 of the 2nd integration circuit 22 is fixed. Thus, when a long dropout is generated, even when the reference voltage Vr1 is decreased, the muting is started when the pre-value holding is stopped and no noise N3 is outputted.
