Title: Waterlevel control device for boiler
Inventor: OKADA TOMIZO
IPC: F22D5/00
Filed: 1992-11-30
Abstract: PURPOSE:To prevent a rapid fall of waterlevel in a drum at the start of steam- feeding by feeding water as soon as an electrode detects no water when it continues to detect water during combustion for more than a given time. CONSTITUTION:Combustion starts, and waterlevel is detected. When an electrode E1 detects no water, a start signal is generated to a water-feeding pump 6 to start water-feeding, which is stopped when E1 detects water. As the desired amount of steam cannot be obtained soon after the combustion starts, the steam is not fed to an objective part, and the electrode E1 continues to detect water because of little amount of evaporation. When the electrode E1 continues to detect for more than a given time, a waterlevel control device 1 starts water- feeding as soon as E1 detects no water, even if the waterlevel does not fall to an electrode E2. Thus, a rapid fall of waterlevel due to the load fluctuation at the start of steam-feeding, and a loss of steam pressure due to the combustion stop can be prevented.

Filed: 1991-12-26
Abstract: PURPOSE:To produce a proper faucet by a method wherein a faucet main body is integrally molded of synthetic resin material of engineering plastic, using a core of an alloy which has a low melting point and is composed of Bi and Sn. CONSTITUTION:A meltable core 1 of a alloy material having a low melting point is set in a pair of molds 50 and 51 to form a molding cavity 52.
