A sealing plug for closing an opening in a component, in particular a body component of a motor vehicle, has a base body which is formed such that it can cover the opening and engage behind an edge of the opening. On the base body a sealing body is arranged, which includes a ring portion and several lamellae with free radial ends, which protrude from the ring portion and are flexible in circumferential direction. The sealing plug is pushed into the opening such that the rear-side latching lip engages behind the edge of the opening, wherein the lamellae of the sealing body are deformed in circumferential direction and center the sealing plug in the opening. After heating of the sealing plug a sealing material of the sealing body, which expands under the influence of heat, encloses the inner edge of the opening as well as radially adjoining regions of the front side and the rear side of the component around the entire circumference of the opening and completely fills the space formed between the supporting lip, the latching lip and the component.

A mask frame assembly including a frame having an opening, a mask having a first end and a second end supported on the frame, and a first member disposed between the first end of the mask and the frame, the first member including a material having a coefficient of thermal expansion greater than that of the mask. A method of manufacturing a display apparatus using the mask frame assembly also is disclosed.

A deposition mask includes a deposition pattern through which a deposition material passes and a distal end extended in a length direction of the deposition mask from the deposition pattern. The distal end includes a dummy pattern between a clamping groove and the deposition pattern in the length direction. The clamping groove and the dummy pattern are provided in plural along a second direction crossing the length direction. In the length direction of the deposition mask, the number of clamping grooves and dummy patterns correspond to each other, the clamping grooves respectively overlap a corresponding dummy pattern, a distal end area at which clamping grooves overlap the corresponding dummy pattern defines a second area of the distal end, and a distal end area at which the clamping grooves do not overlap the corresponding dummy pattern defines a first area of the distal end to which a clamp is applied.

A metal plate for laser processing (such as a stainless steel plate or a titanium plate) and preferably an austenitic stainless steel plate suitable for use as a metal mask or the like which undergoes fine processing with a laser has an average grain diameter d (μm) and a plate thickness t (μm) which satisfy the equation d≦0.0448.Math.t−1.28.

A template for controlling application of material around a protuberance is disclosed. The protuberance extends from a workpiece and has a base. The template comprises a first portion and a second portion, removably attached to the first portion at a boundary. The first portion comprises a first-portion inner peripheral edge that at least partially defines a positioning opening and that is geometrically complementary to at least a portion of the base of the protuberance. The first portion also comprises a first-portion workpiece-facing surface that is adhesive-free. The second portion comprises a visual material-placement indicator, located on a second-portion environment-facing surface. The second portion also comprises an adhesive layer, located on at least a portion of a second-portion workpiece-facing surface.

An apparatus for and method of color-striking a color-strikable article. The method includes the steps of: conveying a color-strikable article within a proximity of an energizer, and selectively color-striking said article with said energizer to produce a predetermined pattern on the article.

A spray coating protection method for electronic devices during metallic particle deposition via spraying is disclosed. The spray coating protection method enables selectivity over the size and location of particle deposition. The spray coating protection method is easy for an automation application, in which multiple electronic devices are processed simultaneously, and is suitable for electronic devices of different shapes and sizes. The spray coating protection method provides resistance to high temperature and high pressure during the spraying operation. The spray coating protection method utilizes masking paper, but additional film materials may be used, both to increase the protective strength of the mask and to enable easy placement and subsequent peel off of the masking paper following the spraying process. The masking paper may be made using a die cutting process and is easily placed onto the electronic device surface to ensure zero contamination from hot and high pressure spray particles.

A deposition apparatus for manufacturing a display device is disclosed. In one aspect, the apparatus includes a substrate fixing portion configured to fix a deposition substrate to a lower portion thereof and a first mask transfer portion placed on one side of the substrate fixing portion and configured to move the deposition mask upwardly such that the deposition mask is formed spaced apart from the deposition substrate by a predetermined distance. The apparatus also includes a substrate transfer portion configured to move the deposition substrate such that the deposition substrate passes over the deposition mask. The apparatus further includes a mask spacing portion positioned on the substrate fixing portion and configured to maintain a substantially uniform distance between the deposition substrate and the deposition mask when the deposition substrate is moved and a deposition source configured to deposit a deposition material on the deposition substrate through the deposition mask.

A mask frame assembly for deposition includes: a frame including an opening portion; a first support extending in a first direction across the opening portion and including opposing ends in the first direction which are each coupled to the frame; a mask stick through which a deposition material passes to a plurality of display regions of a substrate, the mask stick disposed on the first support and extending in a second direction crossing the first direction, the mask stick including: opposing ends in the second direction which are each coupled to the frame, and a deposition region common to each of the plurality of display regions of the substrate; and a magnet coupled to the first support and overlapping the deposition region of the mask stick.

A deposition apparatus is disclosed. In one aspect, the apparatus includes a metal sheet of which an edge portion is integrally combined with a sheet frame and an electrostatic chuck attached to a bottom surface of the metal sheet and configured to pull a substrate based on a static electricity force. The apparatus also includes a metal mask placed below the electrostatic chuck, wherein an edge portion of the metal mask is combined with a mask frame, and wherein the metal mask has a predetermined patterned opening where the substrate is mounted to the upper surface thereof. The apparatus further includes a magnet plate placed above the metal sheet, and configured to pull the metal mask based on a magnetic force so as to attach the substrate to the electrostatic chuck.
