Title: Method for controlling gas-flow rate at time when hot water is resupplied from hot water-supplying apparatus
Inventor: MIYAKE TOMIO
IPC: F24H1/10
Filed: 1991-10-03
Abstract: PURPOSE:To remarkably shorten the time interval of lowering of hot-water temperature at the time when hot water is resupplied, by a method wherein supposing that the rate of water-flow passing through a boiler body is varied from zero to a definite amount of water, at this point of time when the operation of the title apparatus is shifted to steady operation, a differential component at the time when the hot water is resupplied is carried out, when the resupply of the hot water is started. CONSTITUTION:In order that hot water begins to be resupplied after it is stopped, when water begins to be supplied, an actual water-flow rate Q passing through a boiler body varies from zero to a definite amount of the water Qc. Pre-purge is done at this point of time when the water begins to be supplied and the sequence of ignition is done, following which a main burner is started for combustion and is shifted to steady operation. At this point, supposing that the Q is varied from zero to the Qc, a differential component GdQ at the time when the hot water is resupplied is carried out. That is to say, the Q for a time from the time when the water begins to be supplied to the time t is regarded as the zero in calculation and is carried out, and a gas-flow rate, G=GB+GdQ, i.e., the GdQ is added to a criterion gas-flow rate GB, is supplied to the main burner. In this way, since the fluctuation of flow rate is large and the GdQ is increased, the gas-flow rate supplied to the main burner is also increased and thus strong combustion is performed.

Abstract: PURPOSE:To obtain a metal strip with no external flaw on its surface, even when the metal strip provides a soft quality, by coating the surface of the metal strip excepting its side surface with a plastic film thereafter cutting the metal strip into a predetermined width. CONSTITUTION:A metal strip 1, after the total surface excepting its side surface is coated with plastic films 31 and 32, is slitted. Then the metal strip 1 of wide width is cut successively in the lengthwise direction into a predetermined width, obtaining metal streaks 2a-2d, and winding the metal strips 2b, 2c into a coil state, the metal strips 2a, 2d are processed as chips because of poor normal dimensional accuracy. While after slitting, of the plastic films 31b, 31c and 32b, 32c the film, excepting a part necessary for prevention or the like of external flaw is an afterprocess, is stripped and removed. Thus by slitting, even when a material is of relatively soft quality, preventing the generation of the external flaw due to a guide or a retaining jig and the like, the metal strip severely required in its smoothness can be manufactured in a good yield rate.
