Heated architectural panel temperature control systems and methods are provided for heating windows that are formed from heated architectural panels. The liquid is supplied to and recovered from the pressure chamber through the individual supply channel and the individual recovery channel. The lamination is followed by perforations or cuttings, and the method includes at least one of the following steps:A. A first supply hole 2A for supplying one gas and a second supply hole 2B for supplying the other gas are formed in the holding member 1. With the rings mounted to oppositely facing door knobs such that the crossbar spans the leading edge of the door, gravity acting on the counterweight biases the device to rotate such that the bars extend outward from the leading edge and prevent closure of the door by contacting the door jamb. In the apparatus for controlling multiple powers, an on-signal of high level is applied to an input terminal, and an output of a control signal generating unit is sequentially changed to a high level whenever a clock is applied to a clock signal input terminal by one period, so that outputs of the multiple powers are sequentially output.
