Abstract: Proposed is an inspection technology for inspecting a focus ring. A device and a method for inspecting the focus ring including a heat transfer member are proposed. The inspection device may include a housing configured to provide inspection space of the focus ring, with a predetermined area of an upper wall of the housing being formed of a transparent material, a hot plate provided in the housing and configured to heat treat the focus ring while the hot plate supports the focus ring, and an inspection unit configured to inspect a connection state between the focus ring and the heat transfer member by obtaining a thermal image of the focus ring after the focus ring is completely heat treated.

Abstract: Proposed is a method for inspecting for quality of a coating film coated on a component installed in a processing space. The method for inspecting a coating film includes irradiating to irradiate the component with light, observing a coating film to acquire an image of light emitted from the coating film when the irradiating is performed, and inspecting a coating film to inspect the quality of the coating film on the basis of the acquired image of light.

Abstract: The present invention provides a signboard assembly, which is constructed such that, when external force is applied to a signboard, the signboard is rotated, and, when the external force is removed therefrom, the signboard is automatically returned to its original position. The signboard assembly includes the signboard (20) for expressing information, a support unit (30), which rotatably supports the signboard, an elastic member (58), which applies elastic force to the support unit to return the support unit to its original position, and a weight member (80), which maintains the original installation position of the signboard. The signboard assembly of the present invention having the above-mentioned construction is advantageous in that, even if a relatively large external force is applied to the signboard, the signboard is prevented from being damaged and is easily returned to its original position.

Abstract: Provided is a road traffic-control signboard assembly with which a road traffic-control signboard can be assembled while being linked with a vertical support at right angle. The road traffic-control signboard assembly is fitted with and fixed to a road traffic-control signboard stay bar and has a structure of being returned to an original position even if impact by typhoon or collision of vehicles is applied to the road traffic-control signboard. Thus, the road traffic-control signboard assembly prevents a phenomenon that an initial fixed position of the road traffic-control signboard is changed because of impact by typhoon or collision of vehicles which is applied to the road traffic-control signboard, to thereby lose the function of the road traffic-control signboard.
