A washing machine comprises a casing, a top cover installed on an upper surface of the casing, a door installed at the top cover, through which laundry is accommodated into the casing, and a tub installed in the casing, wherein the door is connected to the top cover by a hinge assembly or a damper assembly provided thereat. The hinge assembly includes a first hinge portion, and a second hinge portion having a torsion spring therein. The damper assembly includes a first damper portion, a second damper portion, and a ring member having a round shape and fitted into an outer circumferential surface of the second damper portion. Accordingly, even when the door has a heavy weight due to its material of a reinforcing glass, the hinge assembly or the damper assembly can endure the weight of the door. This may prevent noise or impact occurring when the door is closed.

Washing machine

A surface treatment system is disclosed to form a deposition layer at a surface of an object of surface treatment by using a deposition reaction in which an electrode () for applying power to form a deposition reaction in the deposition chamber () is installed between an inner wall () of the deposition chamber () and an object of surface treatment () and further includes a cooling unit () installed at the inner wall () of the deposition chamber () facing the electrode () and cooling ambient thereof.

Surface treatment system and method

Disclosed are a surface treatment system that includes a deposition chamber () for forming a deposition layer at a surface of an object of surface treatment (); a carrier () for carrying the object of surface treatment () by mounting thereon, and a power applying unit () for forming a deposition reaction by applying a power to the object in the deposition chamber (), wherein the power applying unit () includes a fixed power applying unit () installed in the deposition chamber () and connected to an external power source (); and a movable power applying unit () installed at the carrier () for being electrically connected to the fixed power applying unit () movably as the carrier on which the object of surface treatment () is mounted goes into the deposition chamber and thereby applying a power to the object of surface treatment mounted on the carrier by contacting thereto.

Surface treatment system and method thereof

A surface treatment system in which gas for a deposition reaction is injected into a deposition chamber and power is applied to form a deposition reaction to form a deposition layer at a surface of an object or surface treatment, wherein the deposition chamber has a plurality of deposition spaces disposed in parallel and a convey unit for conveying one or more objects of surface treatment to each deposition space or discharging the objects of surface treatment from each deposition space after a deposition reaction.
