Title: Method of replacing etching gas in gas etching device, and etching device
Inventor: SAKAMOTO TATSUYA
IPC: C23F4/00
Filed: 1991-10-24
Abstract: PURPOSE:To shorten the decompression time of an etching gas supply system. CONSTITUTION:In decompressing, the upper stream side and the downstream side of a mass flow controller 5 are connected by a gas supply bypass pipe 21. In that condition, it is decompressed by a dry pump through a exhaust bypass pipe 23 bypassing a turbo molecular pump 11. After the pressure drops to the pressure at which a turbo molecular pump can operate, it is decompressed with the turbo molecular pump 11. At decompression, gas is sucked without passing the gas through the mass flow controller 5 low in gas circulation ratio, and after the pressure reaches a certain value, the turbo molecular pump 11 is operated.

Title: Measuring instrument for propagation delay time difference between two routes
Inventor: NAKAZAWA YOSHIMI
IPC: H04B7/04
Filed: 1986-11-22
Abstract: PURPOSE:To easily measure the propagation time difference between two routes by detecting the phase difference between a modulated signal passed through a 1st system to be measured and a modulated signal passed through a 2nd system to be measured and displaying it on a display device as the propagation delay time difference between the two routes. CONSTITUTION:A measurement signal is obtained by imposing relatively shallow frequency modulation on the output signal of a carrier generator 1 by a frequency modulator 3 with the output signal of a modulating signal generator 2. A reception part extracts modulated signal components Q1 and Q2 by 1st and 2nd frequency-voltage converters 5 and 6 and a phase detector 9 extracts an output voltage E0 proportional to the phase difference between the modulated signal components Q1 and Q2. Then the output voltage E0 of the phase detector 8 is multiplied by a specific coefficient and the value is displayed on a display device 10, so that the propagation delay time difference  tp between the two routes is measured.
