Title: Dc lighting circuit for small-size discharge lamp
Inventor: MINAMIMURA YUICHI
IPC: H05B41/16
Filed: 1988-08-24
Abstract: PURPOSE:To reduce a power loss by installing a preheating current breaking element and turning on/off a preheating current with a discharge voltage which shows an actual lighting condition to prevent a malfunction. CONSTITUTION:When a lamp 1 is discharged by DC voltage Vcc, a lamp voltage VL discharges at an almost constant voltage even if Vcc changes a little. Then, a Zener diode 5 of an arbitrary DC voltage z is put between the Vcc and a voltage. Thereupon, VI=Vcc>Vz when the lamp 1 does not discharge, and a base current flows to a transistor 6, a preheating current breaking element 4 turns on and a preheating current IH flows. The preheating current IH is controlled to an appropriate value at a preheating control element 3 to preheat the filament of the lamp 1. When the filament is heated and starts discharging, VI=VL<Vz, the breaking element 4 turns off and the current IH is cut off. Thus, the element 4 is on and off with the discharge voltage VL so that such a malfunction as preheating during discharge is prevented and a loss of power can be reduced.

Title: Measuring apparatus
Inventor: FUKUYAMA TATSUO
IPC: G01R27/28
Filed: 1981-12-25
Abstract: PURPOSE:To reduce the measuring time in a measuring apparatus designed to fetch an output signal in the system to be measured with the inputting of a sine wave signal varying discretely in the frequency by varying the frequency at the peak point or the dip point of the sine wave signal. CONSTITUTION:Sine wave-like input signals f1 and f2 have the frequency of a discrete and digital figure. The input signals are generated in such a manner that the signals f1 and f2 both give the dip point at the variation point t1 of the frequency. Switching in the frequency of the input signal causes no step-like change in the level. the use of such input signals prevents transient output from containing output in the system to be measured. As there is no transient phenomena caused in the output signals through two adjacent frequencies give a discrete value, this can reduce the measuring time thereby completing the inspection of mass produced products such as speaker in a short period of time.
