An input buffer includes a delay compensation unit for combining (a) a first signal obtained by buffering an input signal using another signal, which is out of phase with the input signal, with (b) a second signal obtained by buffering the input signal using a reference voltage signal, to output a third signal.
摘要:
Provided is a multilateral continuous uniform rapid cooling device of a double cooling structure in which drinking water such as a beverage or liquor can be rapidly and uniformly discharged without a limitation of amount immediately at an optimum cooling temperature to drink and can be drunken. The device includes: a cooling external tube in which a pair of cooling water pipes respectively are connected to one side and the other side that is opposite to the one side, of the cooling external tube and a cooling internal tube installed in the cooling external tube; a plurality of refrigerant circulating pipes, which are continuously installed inside and outside the cooling internal tube in a spring shape, extend thereto and have ends connected as a refrigerant circulating path of a cooling cycle through a bottom portion of the cooling internal tube and a bottom portion of the cooling external tube; and a plurality of drinking water pipes, which are adjacent to the refrigerant circulating pipes and are continuously installed inside and outside the cooling internal tube and in which drinking water is flowed in an end of the cooling internal tube, is rapidly cooled and is discharged into an end of the cooling external tube.
摘要:
A vehicle mounted type fuel testing apparatus comprises a fuel chamber; a first fuel pump for supplying fuel in the fuel chamber to a sample holding container and an auxiliary fuel tank; an analyzing device for analyzing constituents of the fuel accommodated in the fuel chamber; the auxiliary fuel tank for storing the fuel when it is determined that the fuel is normal fuel; the sample holding container for keeping the fuel when it is determined that the fuel is not normal fuel; a second fuel pump for supplying the fuel in the auxiliary fuel tank to a main fuel tank when the fuel is normal fuel; a third fuel pump for supplying the fuel in the auxiliary fuel tank to the outside when the fuel is not normal fuel; and a controller for controlling the above component parts.
