The total power consumption is judged by a demand controlling means 15d which constantly supervises the power consumption, and generates a demand control signal when the total power consumption is in excess of a prescribed value. With the demand control signal generated, a temperature set point is shifted by a predetermined amount at a time, until the air conditioners 3a-3l are stopped and the total power consumption is reduced to or below the prescribed value. When the power consumption is reduced to a fixed lower limit, the shifting is stopped, and when the power consumption is lowered below the lower limit, the set point is shifted stepwise oppositely, and the stopped air conditioners are restarted.

IPC: A47L1/02
Filed: 1991-09-27
Abstract: PURPOSE:To clean a glass surface accurately with a simple construction by a method wherein the periphery on the suction side of a vacuum sucker is formed at a knife edge part and a wheel lift mechanism of one vacuum sucker is operated to make a smooth surface of the vacuum sucker move in sliding contact while decreasing a contact resistance in the contact of the one vacuum sucker. CONSTITUTION:The inside of a vacuum sucker 2 is made to have a negative pressure to reduce a contact resistance between one vacuum sucker and a glass surface is made smaller than the contact resistance of the other vacuum sucker. For example, a lift wheel 9 of the vacuum sucker 2 is lowered to the right hand and one part of the contact part between the sucker 2 and the glass surface is separated from the glass surface so that a part of the contact resistance is turned to a rolling friction between the lift wheel and the glass surface from the state of static friction to reduce the contact resistance of the sucker 2 smaller than that of the left sucker. Then, a piston rod 26 of a cylinder as sucker moving means 6 is extended so that the vacuum sucker with a smaller contact resistance alone is moved in the extending direction of the piston rod 26. Thus, the rim part of the vacuum sucker 2 is formed at the knife edge part 5 thereby enabling cleaning with the movement of the vacuum sucker 2.

IPC: B65H7/06
Filed: 1993-11-05
Abstract: PURPOSE:To improve the workability at the time when paper jam is generated, and to downsize a device by providing a control means for reversely rotating a driving motor in response to the detecting signal from a paper-jam detecting means and for canceling engagement of an epicyclic gear and each first stage gear of a gear transmitting means to stop the driving motor. CONSTITUTION:A main control unit 49 judges the generation of paper-jam when a detecting switch SW3 is not turned on within the ON-limit time thereof, and outputs the reverse rotation command signal to a motor driving circuit 46. Rotation of a driving motor 45, namely, a driving gear 1 is switched from the direction D to the direction C, and after a little time is passed, the driving motor 45 is stopped. Then, a sun gear 3 starts to be rotated in the direction D, and epicyclic gears 5, 6 are rotated around of the periphery of the sun gear 3 to cancel the engagement thereof with the sun gear 20 and the gear 30 for stop. Consequently, though the energizing force of an energizing means is applied to a driven roller 32 and the driven roller 32 pressure-contacts with a fixing roller 26, a load for drawing a jammed paper 9 is remarkably reduced.
