Abstract: PURPOSE:To prevent overload of carrying-out machines for scum in machines and installations for carrying out scum of grit chambers in sewage treatment plants, etc. by checking the loading condition of the scum on the carrying-out machines and controlling the operation of dust removers. CONSTITUTION:In this scum and dust removing system, dust removers 1 are installed in plural grit chambers, and the scum raked up with rakes 2 is charged into a carrying-out machine 3 and is then fed to a washing device, etc. not shown by a carrying-out machine 4.

Abstract: PURPOSE: To sense a flow by making a through channel under one half body of a beam and a cavity under the other half body. CONSTITUTION: An insulating film 2 of about 0.5 micron thick is coated with a metal 3 of about 3 micron thick to form a beam 1 which is then supported above a semiconductor substrate 31 through a support 4 of same thickness as the insulating film 2 and integrated therewith.
