Abstract: A double clutch transmission (DCT) provides eight forward speeds and one reverse speed while minimizing the number of gear trains used for changing speed and the whole length thereof. In particular, the DCT has a simple structure using four or five gear trains and four synchro devices and is capable of providing eight forward speeds and one reverse speed while reducing the entire weight thereof. In a conventional DCT, when a gear train is added to increase the number of speed stages, the whole length thereof is increased. The provided DCT can minimize the whole length and the weight thereof, thereby reducing the manufacturing cost, the number of parts, and the fuel efficiency.

Abstract: An oven, which both satisfies heat insulating and cooling of a door by adjusting an air flow in channels formed in the door. The oven includes a plurality of channels provided in a door, into which external air flows, accompanied with air discharged by a discharge duct, such that the air flows in the plurality of the channels, and a flow conversion part formed above at least one of the plurality of the channels for stagnating the flow of air. Since the door insulates a cooking chamber from heat and is cooled using a difference of pressures between upper and lower portions of the door, the oven concurrently satisfies conflicting two requirements, such as heat insulating and cooling of the door.
