Abstract:
Decorative bulb with multiple light points and double circuits, including a vacuumized glass-made transparent housing in which an insulating bead is disposed. Two sets of leads are separately located on the bead. Two tungsten filaments are respectively fixedly connected between the portions of the two sets of leads extending into the housing. The two tungsten filaments are respectively positioned in a front and a rear positions. The portions of the two sets of leads extending out of the housing are connected to the double circuits for controlling powering on/off of the bulb. Accordingly, one single decorative bulb has multiple light points insides, which can be respectively controlled to achieve various light-emitting decorative effects.
Abstract:
A display includes a baseplate and an emitter formed on the baseplate. The display also includes a faceplate having a cathodoluminescent coating on a surface facing the baseplate and the emitter. A plurality of spacers separate the faceplate and the baseplate to prevent bowing of the faceplate or the baseplate towards each other. The spacers are formed from silicon, simplifying field emission device assembly and resulting in a superior display.

Abstract:
The present invention relates to a Christmas bulb structure, which is provided with a pair of conducting wire in the bulb and one filament and two or more fuses connecting with the two conducting wires in parallel. It increases the well rate of the assembled light string and prevents the bulb from broken caused of the filament being burned out. And also it lengthens the used period of the bulb and the light string.
Abstract:
An image-forming apparatus comprises a rear plate including electron-emitting devices formed thereon, a face plate including a fluorescent film formed thereon and being disposed to face the rear plate, a spacer in the form of a flat plate disposed between the rear plate and the face plate, and an outer frame surrounding peripheral edges of the rear plate and the face plate. Electrons emitted from the electron-emitting devices are irradiated to the fluorescent film to thereby display an image under condition where an inner space of a container constructed by the rear plate, the face plate and the outer frame is evacuated through a vent tube into a depressurized state. The vent tube is attached to a side of the outer frame that is positioned across an imaginary extension of the flat-plate spacer in the longitudinal direction thereof, or to the face plate or the rear plate in the vicinity of that side of the outer frame. With such arrangements, evacuation conductance is increased to reduce an evacuation time, and a higher vacuum level is achieved in the container so that an image can be stably displayed for a long term.
Abstract:
The present invention relates to a supporting spacer mounting structure and method for a field emission display. By using a supporting spacer structure being cross-shaped or rectangle-shaped and being made of glass, ceramics or metal, and employing the vacuum absorption of a clipping arm with special design and the real time monitoring of a monitoring lens, the position-aligning is preliminarily performed on a supporting spacer, and then the supporting spacer is positioned on a required location so as to provide the supporting force needed by a display.
Abstract:
A mounting member (50, 50null, 50null, 50nullnull) for an arc tube/shroud combination comprises an annulus (52). The annulus (52) has at least one mounting tab (54) depending from an outer edge thereof and two spaced apart arc tube-pinch seal-engaging ribs (56, 58) spanning the diameter of the annulus for frictionally engaging the pinch seals. Holding tabs (62) depending from the annulus mount the annulus to a shroud. In a preferred embodiment the ribs (56, 58) have upstanding projections (60) that engage the pinch seals and provide the friction fit necessary for holding the pinch seals.
