Abstract:
A discharge lamp lighting apparatus includes a housing that is formed by a box-shaped housing main body, which has therein a first circuit including both a first connection connector that protrudes toward an opening and a first electronic part group, and a discharge lamp bulb attached to the outside of the housing main body. A housing cover has a heat dissipating metal body on a back surface of a substrate having mounted thereon both a second connection connector that protrudes at a position corresponding to the first connection connector and a second electronic part group having lower heat resistance than the first electronic part group, and that is attached to the opening. The second connection connector is mounted to the first connector when the housing cover is attached to the housing main body.

A lamp assembling apparatus that assembles a lamp unit of an optical engine having a lamp and a lamp housing to support the lamp, and includes an illuminator through which light emitted from the lamp of the lamp unit passes, a screen on which an image is formed by the light passed through the illuminator, a lamp control unit to adjust a position of the lamp with respect to the lamp housing, a lamp fastening unit to fasten the lamp to the lamp housing in a state that the lamp is adjusted in position by the lamp control unit, and a controller to determine the image formed on the screen and to control the lamp control unit and the lamp fastening unit to bring the lamp into focus and then fasten the lamp to the lamp housing.
Abstract:
An image display apparatus is composed of a substrate on which an electrode receiving the supply of a power source is formed. By providing an electroconductive member which adheres to the electrode through a hole and seals the hole, the formation of a hermetic lead-in terminal is made to be easy.
Abstract:
The disclosure describes a method of attaching and electrically connecting first and second planar substrates, wherein the first and second substrates have inwardly-facing surfaces with matching patterns of bond pads. The method includes adjusting a wire bonder's tear length to a setting which leaves a projecting tail of severed bond wire at a terminating wedge bond connection. Further steps include making a wedge bond to an individual bond pad of the first planar substrate with bond wire from the wire bonder, and then severing the bond wire adjacent said wedge bond. The adjusted tear length of the wire bonder results in a tail of severed bond wire which projects from said wedge bond and said individual bond pad. Subsequent steps include positioning the first and second planar substrates with their inwardly facing surfaces facing each other, aligning the matching bond pad patterns of the first and second planar substrates, and pressing the first and second planar substrates against each other. The bond wire tail deforms between the bond pads of the first and second planar substrates to conductively bond therebetween.
Abstract:
The disclosure concerns electron tubes. A tube such as a cathode-ray tube consists of several parts, namely the stem, the neck, the cone and the screen of the front face. To build a tube such as this more compactly while, at the same time, improving the quality of the fabrication, a new construction of the neck is proposed. In the prior art, the neck is a glass tube to which there is soldered a glass stem through which pass the connection terminals towards the various electrodes, internal to the tube. Here, the neck is built in the form of a stack of alternating metallic rings and ceramic rings. The metallic rings are used for the supporting of and electrical connection to the internal electrodes. The ceramic rings are used to insulate the metallic rings. The brazings between metallic rings and ceramic rings provide for vacuum tightness. The base of the tube is a ceramic washer without drillings other than lateral ones for the connections to pass through. The connections are made chiefly around the neck on the metallic rings.
Abstract:
An apparatus for welding the base pins of a fluorescent lamp, comprising two pairs of electrode holders disposed along the direction of advancement of said fluorescent lamp with a predetermined distance therebetween and removably holding welding electrodes, a first switch connected to the welding electrodes held by one pair of the two pairs of said electrode holders, a second switch connected to the welding electrodes held by the other pair of the two pairs of said electrode holders, and a switch control connected to the first and second switches, the apparatus being characterized in that the switching operations of the first and second switches are staggered in time by the switch control means in relation to the stepwise movement of the fluorescent lamp.
Abstract:
A fluorescent tube holder comprises a fluorescent tube holding chuck having a pair of releasable claws for holding the fluorescent tube, and a base chuck having a pair of releasable claws for holding the base of the fluorescent tube on the outer periphery thereof. The base chuck is movable toward and away from an end of the fluorescent tube held by said fluorescent tube holding chuck.
Abstract:
A fluorescent display tube includes in the casing a plurality of anode display portions formed of segment electrodes each having a fluorescent material layer thereon, cathodes and control electrodes disposed opposite to the anode display portions, lead-in wires led out in an air-tight manner from the casing and electrically connected to the segment electrodes, the control electrodes and the cathodes, a plurality of conductive section each connected to the adjacent common segment electrodes through a corresponding conductive wiring film, the lead-in wires for the segment electrode terminal each having at the end thereof in the casing a contact with a spring portion, the contact coming in contact with the corresponding conductive section by the action of the spring portion as well as a conductive adhesive applied thereto thereby establishing an electrical connection.A method of producing a fluorescent display tube includes forming an anode plate, forming electrode assembly framework, forming a casing using the anode plate, upper cover and the electrode assembly framework by sealing and removing unnecessary parts after sealing.
Abstract:
A method for securing an electrode to the electrode holder in a high pressure sodium discharge lamp and resulting article, which method, involves spot welding a thin niobium, tantalum or titanium wire across the flattened end of the electrode holder and thereafter spot welding the electrode rod to the electrode holder perpendicular to the axis of the thin wire to provide a strong bond between the electrode and the electrode holder.
Abstract:
A method of introducing a high voltage electrical conductor through the neck of a television cathode ray tube comprising the providing of a gun-base assembly comprising a hollow glass stub tubulation on one end of which is an annular glass base carrying an electron gun assembly. On the distal end of the stub tubulation is temporarily secured a hollow holder. An electrical conductor is provided which passes through the stub tubulation. The gun-base assembly is inserted into the neck and hermetically bonded to the neck. The cathode ray tube is evacuated through the stub tubulation and the temporary holder. Heat is applied circumferentially to the stub tubulation to soften and pinch off the tubulation, sealing the evacuated tube against re-entry of air. The temporary holder is detached from the stub tubulation to form a cup in the end of the tubulation for receiving an electrical connector.
