Abstract: PROBLEM TO BE SOLVED: To sufficiently secure the amount of spray by making sufficiently large a pressure difference applied on a spray adjusting valve upon low load operation of a boiler, and keep substantially unchanged temperature of superheated vapor even when boiler load is raised or varied. SOLUTION: A boiler is adapted to include spray adjusting valves 7a, 7b for spraying supply water 1 to a superheater 5. Herein, there are provided a spray differential pressure adjusting valve 12 provided on a main water supply line 11 for guiding supply water to a fire furnace 4, a vapor pressure detector 13 and a supply water pressure detector 14 each for detecting pressure P1 of superheated vapor coming out from the superheater and pressure P0 of the supply water, and a differential pressure controller 16 for adjusting the spray differential pressure adjusting valve from detected pressures of the vapor pressure detector and the supply water pressure detector to control differential pressure between the superheated vapor and the supply water.  The spray differential pressure adjusting valve 12 is adjusted based upon a deviation between a pressure difference ΔP1 between the superheated vapor and the supply water and a predetermined pressure difference ΔP2 due to an output instruction value.

Title: Deposited-film forming method
Inventor: SAKAI AKIRA
IPC: H01L21/3065
Filed: 1989-10-12
Abstract: PURPOSE:To form a crystal silicon film of crystal grain having large grain size by performing an etching step and a first depositing step at the initial period of the formation of a deposited film once, or repeating those steps, and providing a step which is transferred to a second depositing step. CONSTITUTION:The flow rate of SiF4 gas which is introduced through a gas introducing pipe 1 at the initial stage of deposition is 76sccm, and the gas is introduced at an equal interval. The flow rate of hydrogen gas which is introduced through a gas introducing pipe 2 is slowly decreased at an equal interval from 40sccm, and the gas is introduced by adjusting the flow rate so that the flow rate reaches the constant value of 30sccm. Therefore, the time of the first depositing step and the time of an etching step are constant. Since the etching speed of hydrogen plasma is approximately proportional to the introducing amount of the hydrogen gas, the speed is high at the initial stage and gradually decreases with time. The first depositings step and the etching steps are repeated and the etching is gradually weakened in this way, and a second depositing is started. Thus, the deposited film is formed.
