Abstract: This disclosure describes method and apparatus useful in the manufacture of shadow mask color cathode ray tubes of the flat tension mask type, wherein the shadow masks and associated glass front panels are respectively interchangeable during mask-panel assembly.

Abstract: An improved method of mounting electroluminescent semiconductor laser devices onto heatsinks, wherein easy subsequent location of the lasing spot of the laser is provided, is disclosed. The method comprises placing a reference mark on the front of the heatsink, wetting solder to the heatsink and allowing it to harden, contacting the laser device to the hardened solder, applying current to the laser device to cause light emission, aligning the lasing spot to the reference mark and bonding the laser device to the heatsink while maintaining such alignment.

Abstract: There is disclosed a method of installing a mount assembly in a cathode ray tube wherein convergence characteristics are enhanced by properly setting levels of tube of a color cathode ray tube and of an electron gun. When a neck portion of the tube and a stem structure mounted with the electron gun are sealed to each other by heating, a distance between a standard level of the tube and that of the electron gun is measured. Comparison/arithmetic processing is effected both on the thus measured value and on a previously stored standard distance to seek a difference between the two values. The tube body or the electron gun is controlled by a moving operation so that the difference falls within an allowable value. After this, the sealing process is carried out.

Abstract: A method and an apparatus for position orienting a base assembly of a metal halide lamp is describe for maintaining the curved arc tube in the upward position when the lamp is inserted in a socket. Once the lamp has been fully assembled and sealed a locator structure is attached to the base shell in order to create a base assembly which will properly position the lamp when it is in the socket. The welding apparatus of the present invention resistance welds the locator structure onto the base shell once the locator structure has been aligned approximately 90 degrees counterclockwise from the tip of the curved portion of the arc tube when viewed from the dome end of the lamp. The lamp resulting from the method and use of the apparatus will be more inexpensive and will not have the problems of a loose base or a cracked seal.

Abstract: The present invention relates to a headlight comprising a glass lens element and a support element, such as a reflector, of thermoplastic material, such elements being associated at their periphery by matching assembly shapes of interlocking type which are fixed by an assembly glue. The headlight is characterized in that the lens is provided with three fixed internal supports cast in one piece with the lens which define a bearing plane. The lens is also provided with a further internal support having a positive offset with respect to the bearing plane. This offset is compensated by an interposed support member whose thickness is determined by the actual features of the lens.

Abstract: A three electron gun color picture tube includes phosphorescent marks attached to the rear side fo the shadow mask. These marks can be used for checking the exact position of the electron beams during adjustment.

Abstract: The present invention concerns a process and a device for aligning and centering an assembly of electron-guns on a color television tube during the manufacturing process. To do this, the image of the markings of the assembly of electron-guns is formed on analyzers, each comprising a charge-coupled photosensitive strip. The alignment is observed when the comparison signal is lower than a predetermined value. Instead of markings, the image of the sections of the assembly of guns can be used as the section comprising the grid G4 in the cup.

Abstract: A halogen bulb lamp assembly manufactured by mounting a previously aligned halogen bulb unit in a one-piece molded plastic rectangular reflector with a mirrorized paraboloidal inner surface. The halogen bulb unit has a pair of spaced connector pins that are coated with an epoxy adhesive and inserted into a pair of stepped through bores in the reflector. The pins are shaped to force epoxy uniformly into the larger portions of the reflector bores, and the ends of the pins project from the rear of the reflector and are spot welded to terminals that have barbed projections pressed into the rear of the reflector.

Abstract: A method of manufacturing a sealed beam lamp wherein an adhesive activated by ultraviolet light is used for bonding the terminals of a light source assembly to a reflector characterized in that the ultraviolet light is directed through a lens bonded to the reflector for activating the adhesive and thereby fixing the light source assembly to the reflector.

Abstract: An electron gun for a camera tube includes an anode and a cathode. The cathode is assembled in a cathode support which can very readily be adjusted relative to the anode in the non-connected condition. In particular, the cathode support and the anode are movable radially with respect to each other and with respect to an axis. An emissive cathode surface and a part of the anode extending perpendicular to the axis remain accurately parallel to each other during the radial movement. As a result of this it is possible to cause the central path of the generated electron beam and the gun axis to coincide so that extra correction coils for aligning the electron beam may be omitted.

Abstract: A lamp having a minimum number of parts consisting of lamp terminals, a lens, light bulb and reflector, the lens and reflector forming a sealed envelope containing the light bulb, the bulb lead wires being secured directly to the inner ends of the terminals positioned within the envelope and constituting a light source assembly. The terminals extend through openings formed at the rear of the reflector, the openings being large enough to allow adjustment of the light source assembly with respect to the reflector in the X-Y-Z axes by manipulating the light source assembly from the rear of and outside the lamp envelope thus simultaneously compensating for variations between bulbs, reflectors and lenses. The lamp is aimed simultaneously with adjustment of said light source assembly. The defined construction eliminates the need for mounting and sealing ferrules and separate lead-in wires between the terminals and the bulb.
