Title: Sheet conveyer by sensitivity material belt
Inventor: NOGUCHI KOICHI
IPC: B65H5/00
Filed: 1990-04-25
Abstract: PURPOSE:To more stably hold and convey a sheet by on-off controlling a light emitting element of a photoelectricity removal means in such a manner that an electrostatic pattern is generated coarse in a region corresponding to the point end part of a conveyed sheet and dense in a region corresponding to a part to the rear end of the conveyed sheet thereafter. CONSTITUTION:A light emitting element of a photoelectricity removal means 21 is on-off controlled to form an electrostatic pattern of low density in a region corresponding to the point end part of a conveyed sheet and an electrostatic pattern of high density in a region thereafter. In this way, the sheet, when it is separated from a belt 24 by utilizing its curvature, is easily separated by decreasing attraction force relating to the attracted sheet in a region on the belt 24 corresponding to the point end part of the sheet. The sheet is surely held to the conveying belt 24 and conveyed, even when attraction force is weak in the point end part, by increasing the attraction force of the attracted sheet in a region corresponding to a part after the sheet point end part.

CONSTITUTION:If fuel is fed to a burner 2 through a fuel feed pipe 3 and combustion is started by an ignitor 4, the produced high temperature combustion exhaust gas flows along a wall surface, whereon an oxygen concentration cell housing part 7 is installed, by means of a polarizing plate 6 in a combustion chamber 5, and is exhausted to the outside of the chamber by a blower 10 for the combustion air after passing a heat exchanger 8 as said oxygen concentration cell housing part 7 is increased in temperature by means of the combustion exhaust gas. Simultaneously, a part of the exhaust gas enters a conduit 11 and flows in the blower 10 for combustion air after flowing in contact with the one surface of the oxygen concentration cell 9. In which case, the oxygen concentration in the exhaust gas is as low as a few percent, and since a difference between the oxygen concentration in the blower and that on the surface, along which the indoor air flows, of the oxygen concentration cell 9, is produced, a voltage corresponding to the difference in concentration is generated. A controller 16 is operated through receipt of the voltage signal, and a motor 15 is controlled so that a voltage output attains the previously set value to produce the air quantity which is well suited for a predetermined combustion quantity.
