Title: Gas flowmeter
Inventor: TANAKA YUTAKA
IPC: G01F7/00
Filed: 1999-08-03
Abstract: PROBLEM TO BE SOLVED: To easily constitute a small-sized gas flowmeter with wide rangeability suitable for a gas meter for business use at a low cost. SOLUTION: A gas is carried from an inflow passage 11 to a dead-reckoning gas flowmeter 4 through an upstream passage 5 and a connecting passage 12. The pressure loss P1-P2 of the dead-reckoning gas flowmeter 4 is small with a minute flow rate of 0-200 l/h. Accordingly, flexible diaphragms 9A, 9B provided on the upper part of the liquid columns (water) of a U-shaped pipe liquid column reacting means 8 are located in the shown lines. Thus, the sectional area of the upstream passage 5 is small, and the flow velocity is sensed by a thermal flow sensor 6 to measure the flow rate. The pressure loss is large with a large flow rate, and the flexible diaphragm 9A is lowered to a position 9A' to increase the passage sectional area. The flow rate at this time is measured by the-dead-reckoning gas flowmeter 4.

IPC: H01L21/3213
Filed: 1988-09-05
Abstract: PURPOSE: To improve the etch speed and to increase the ratio of the etch speed of a photoresist by conducting etching in a plasma consisting of a chlorofluorocarbon gas the number of fluorine atoms of which is greater than the number of chlorine atoms and of oxygen at a prescribed flow rate. CONSTITUTION: Etching is performed in a CClF3 /O2 containing 50% of O2 or over (preferably 50 to 95%) with respect to the entire mixture so as to much increase the etch speed of a material such as tungsten. Moreover, the etch speed of a photoresist is decreased in this system in comparison with a CF4 /O2 plasma and the etch speed ratio of the photoresist is maximized. This is estimated because lots of fluorine more than chlorine is in existence in the chlorofluorocarbon, and at least the degree of chlorine is in existence.
