Abstract: A microwave oven in which a power transmission transmitting driving force of a motor moves a tray right and left without direct contact with the tray. The microwave oven includes a support disposed between a bottom plate and the tray to support the tray and the power transmission transmitting driving force of the motor to the support such that the support linearly travels. The shape of an oval guide hole formed in the support is changed to adjust the stopping time of the support at the rightmost or leftmost side. The tray linearly travels together with the support when the support linearly travels. The microwave oven further includes a tray restriction device or a tray moving device for guiding the linear movement of the tray. The tray restriction device and the tray moving device are implemented by locking steps, grooves, protrusions, or rollers.

Abstract: The present invention relates to an ALD apparatus, and particularly relates to an ALD apparatus that is suitable for rapidly depositing a thin film on a substrate having an actual area that is larger than a planar substrate. In the reaction chamber of the ALD apparatus according to an exemplary embodiment of the present invention, more gas is supplied to a portion where more gas is required by having differences in the space for gas to flow rather than supplying the gas in a constant flux and a constant flow velocity such that the time required for supplying reactant gases and waste of reactant gases may be minimized to increase productivity of the ALD apparatus. The ceiling of the reaction space is shaped to provide a nonuniform gap over the substrate.

Abstract: A microwave oven in which there is substantially no difference between time when a linearly traveling tray travels from the right side to the left side of a cooking chamber and time when the linearly traveling tray stays at the right side or the left side. The microwave oven includes a linearly traveling tray having a guide channel or hole guiding a linear movement and a power transmission transmitting driving power of a motor to the tray. The guide channel and the guide hole have an oval shape and adjust the staying time at the rightmost or leftmost side in the traveling region. A rotation tray having a locking step formed in the lower surface thereof is further provided. The power transmission may include a linkage, protrusion and/or a roller, and their modifications. Food is uniformly cooked at any place of the cooking chamber, and a user can easily clean and reinstall the tray.

Abstract: A microwave oven for enabling smooth rotation and linear reciprocation of a turntable is provided with a turntable installed therein to rotate and linearly reciprocate within a cooking compartment. The microwave oven includes a reciprocation guidance member, for supporting the turntable, provided between the turntable and the bottom of the cooking compartment. The reciprocation guidance member is moveable with the turntable in a linearly reciprocating direction. Through the use of such a reciprocation guidance member, it is possible to prevent interference between the rotation and the linear reciprocation of the turntable, resulting in smooth rotation and reciprocation of the turntable.
