Title: Method of distinguishing irregular flicker of fluorescent lamp
Inventor: WANI KOICHI
IPC: H01J9/42
Filed: 1987-07-17
Abstract: PURPOSE:To make it possible to find out a lamp tends to generate irregular flicker early in the lifetime by monitoring the generation of the discontinuance of the anode oscillation applying a DC power voltage superposed with a triangular wave voltage having a rise time longer than its fall time and a specified amplitude and frequency so as to distinguish irregular flicker of light output. CONSTITUTION:A fluorescent lamp is started at the minimum value of the frequency [f]of a signal wave 2 and of the amplitude Va of a superposed triangular wave voltage, and the frequency [f] is increased up to the maximum value continuously or discretely. During this time period, the generation of the anode oscillation is monitored with an oscilloscope 5, and if the anode oscillation is discontinued at a frequency the corresponding frequency or the range of the frequency is recorded. Then the amplitude Va is increased by a small increment and the frequency [f] is changed from the minimum value to the maximum value similarly to monitor the generation of the anode oscillation. The frequency [f] and the amplitude Va of the said triangular wave are made to be 20Hz-1 kHz and 20-80V respectively. Thereby fluorescent lamps tends to generate the irregular flicker can be found out easily in the lifetime.

IPC: C03B5/26
Filed: 1993-06-25
Abstract: PURPOSE:To supply even a small amt. of the glass fused in a crucible with a high metering accuracy. CONSTITUTION:The fused glass 4 in the crucible 1 attains the state of floating on fused tin 6 by a difference in sp. gr. from the fused tin 6 when metered glass pellets 2 are melted by heating together with the tin 5 (see Fig. 1(b)). The fused tin 6 is, therefore, interposed between the fused glass 4 and the inside wall of the crucible 1 if the fused glass 4 is discharged from an opening 4 of the crucible by tilting the crucible 1 and, therefore, the adhesion of the fused glass 4 to the inside wall of the crucible 1 is reduced and the greater part of the fused glass 4 is made to flow out of the crucible (see Fig. 1(c). The fused tin 6 is made to flow out simultaneously with the fused glass 4 at this time and, therefore, the fused tin and the fused glass are separated in the ensuing stage and thereafter, only the fused glass 4 is supplied to metal molds.

Abstract: PURPOSE:To facilitate driving and pulling-out of an underground penetrating member, by a method wherein 4 oscillating shafts each having an eccentric weight are disposed on the same plane to the upper end of the underground penetrating member, and the relative position of the eccentric weight can be varied through remote control. CONSTITUTION:4 oscillating shafts A, A', B, and B', each having an eccentric weight W with the same weight, are longitudinally and laterally disposed on the same plane to form a composite vibration oscillator 22. The composite vibration oscillator 22 is disposed on a steel pile 24 through a coupling tool 28, and vibration is generated through the rotation of the oscillating shafts A, A', B, and B' to effect driving and pulling-out of the steel pipe pile 24. In which case, in case driving or pulling-out becomes difficult to perform, the phase angles and rotary angles of the oscillating shafts A, A', B, and B' are varied through remote control without stopping the generation of vibration. This causes variation of vibration exerted on the steel pipe pile, and facilitates driving and pulling-out of the steel pipe pile.
