A mask frame assembly may be constructed with a supporting bar and a plurality of stick-type split masks installed on a frame while crossing each other. The supporting bar and the split masks are fixed to each other by being welded to each other at points where the supporting bar and the plurality of split masks cross, and a partial cutting portion is formed around each of the welding points by cutting portions of the split masks. By using the supporting bar, the split masks are prevented from drooping, and adhesion between the split masks and a substrate is enhanced.

A one-dimensional tension mask-frame assembly for a color cathode ray tube includes a rectangular frame whose top and bottom members each have inwardly flexed upstanding portions with a spring constant, and a rectangular mask secured to the frame along the free edges of the upstanding frame portions, the frame portions maintaining the mask in a state of tension during thermal expansion of the mask. The assembly is useful in color display applications such as T.V.

A shadow frame and a method of manufacturing the shadow frame are disclosed. The shadow frame is utilized in photoelectrical semiconductor manufacturing processes and is utilized for fixing a glass substrate by combing with a support base used to carry the glass substrate. The shadow frame has a plurality of frame components and welding parts, and the frame components are adjoined at the welding parts to form the shadow frame. The provided shadow frame and its manufacturing method are capable of improving the utility rate of the substrate used to manufacture the shadow frame, avoiding a waste of the substrate, and thereby capable of reducing the manufacturing cost.

The invention relates to a mask-frame assembly for use as a color-selecting-electrode system in a color-television tube. The structure features of the mask allow for a simplified method of manufacturing such an assembly. The mask and frame are subjected to a common surface treatment in accordance with a particular temperature program after joining them together at given points by spot welding.

Mask-frame assembly and method of manufacturing the same

The invention relates to a mask-frame combination as a color selection electrode in a color television tube and has an object to provide a simplified manufacturing method for such electrode. The object is achieved through common transverse surface treatment of mask and frame according to their connection by spot welds according to the invention positioned according to a temperature program according to the invention. Key Benefits: The new series of manufacturing steps saves a continuous furnace. By changing the maximum temperature the coincidence is low, so that the specification of the screening tool is fixed.

Mask-frame assembly and its manufacturing process

Die Erfindung betrifft eine Masken-Rahmen-Kombination als Farbauswahlelektrode in einer Farbfernsehrohre und hat zur Aufgabe, ein vereinfachtes Fertigungsverfahren fur eine solche Elektrode anzugeben Die Losung der Aufgabe erfolgt durch gemeinsame Querflachenbehandlung von Maske und Rahmen nach deren Verbindung durch erfindungsgemas positionierte Punktschweisungen nach einem erfindungsgemasen Temperaturprogramm Hauptvorteile: Die neue Folge der Fertigungsschritte spart einen Durchlaufofen ein Durch veranderte Maximaltemperatur ist das Zusammenfallen gering, so das die Vorgabe des Maskenwerkzeugs festliegt
