Abstract: The light emitted from a focal position-detecting light source 38 and reflected from a reflector 12 is projected onto a screen 341, and a projected image on the screen 341 is detected by a focal position-detecting camera 35. Based on this projected image, the focal position-detecting light source 38 is moved by a position adjusting system 37 so as to place the focal position-detecting light source 38 at a focal position of the reflector 12, and the position of the focal position-detecting light source 38 at this time is detected as the focal position of the reflector 12. When the focal position of the reflector 12 is detected, the projected image on the screen 341 detected by the focal position-detecting camera 35 is used, and, therefore, the conventional measurement by a three dimensional measuring instrument is made unnecessary, thereby improving the working efficiency.

Abstract: A detection and repair system includes an optical microscope, an image-retrieving device, an emission detector, a data controller, and a laser beam generator. When detecting the location of a defect, the system charges a detected region of an organic electroluminescent device with a negative bias or low forward bias before the device is lighted on. Then, the emission detector detects the locations of defects, which generate emission such as photons, thermal or IR emission, in an enlarged image. The laser beam generator generates a laser beam, which is used to isolate one of the defects. Furthermore, this invention also discloses a method for detecting and repairing an organic electroluminescent device.

Abstract: In a bond step, one end of ground electrode is bonded to a metallic housing. In a provisional bending step performed after the bonding step, an intermediate portion of the ground electrode is bent with a pressing die so that the other end of the ground electrode is opposed to a distal end surface of a center electrode. In a regular bending step performed after the provisional bending step, the position of the other end of the ground electrode is adjusted so as to adjust the dimension of a spark gap. Receiving dies are prepared for regulating a shift range of a distal end surface of the other end of the ground electrode in a direction perpendicular to an axial line of the center electrode in the process of bending the intermediate portion of the ground electrode in the provisional bending step. In the provisional bending step, the intermediate portion of the ground electrode is bent until the distal end surface of the other end of the ground electrode is brought into contact with the receiving dies.

A measurement point on the outline of the other spark gap definition portion is found such that the distance between the measurement point and the reference point is the shortest.

Abstract: A laser beam is emitted form one side to a pair of square holes, while an electron gun assembly is being rotated on the tube axis of a color cathode-ray tube. The resulting diffraction pattern is sensed. When diffraction images included in the diffraction pattern are processed and a zero-order diffraction image and at least a first-order diffraction image are sensed in the pattern, the distance between the center of the zero-order diffraction image and the center of the first-order diffraction image is measured. The rotational position at which the distance is the smallest is sensed. The electron gun assembly is rotated to the position and held in place. Consequently, high-speed positioning is done with high rotation accuracy, which helps manufacture high-quality color cathode-ray tubes.

The linear polarized light is illuminated on the electron gun and the light reflected by this electron gun is observed by a light polarization unit to detect the position deviation between grids of the electron gun.

Abstract: A device for measuring a distance between a panel and a shadow mask included in a color CRT (Cathode Ray Tube) of the present invention includes a range finder having an emitter for emitting an ultrasonic pulse, and a receiver for receiving it. The emitter emits the ultrasonic pulse toward the inner surface of the panel on which the shadow mask is mounted. The distance or so-called Q value is measured on the basis of a lag between the time when a first reflection from the shadow mask reaches the receiver and the time when a second reflection from the inner surface of the panel reaches the receiver. The device is capable of measuring the Q value without resorting to the removal of the shadow mask, and measuring Q values even smaller than 5 mm without contacting the shadow mask. In addition, the device is easy to handle and small size.

When the shape of the mark comes to correspond to a predetermined pattern, the center electrode is stopped from rotating and fitted solidly with the ground electrode.

Abstract: A process for assembling a laser and an apparatus used to assemble a laser is disclosed. The laser contains, among other components, a semiconductor chip, a lens and an optical fiber. The chip and lens are disposed in a housing. The optical fiber is disposed in a transmission assembly. The process replaces a tedious manual method for aligning the lens housing and the transmission assembly.

The apparatus restrains the lens housing while the housing is placed in contact with the transmission assembly. The apparatus provides electrical contacts which are placed into electrical connection with the leads on the lens housing. Electrical current is then provided which is conducted to the chip. The chip generates a beam of light which is focused by the lens into the fiber and then transmitted by the fiber. The power of the beam of light in the fiber is measured.

Abstract: A production system is disclosed for registering flat tension masks to screen bearing face panels in the manufacture of cathode ray tubes. Both the panel and mask are supported in modules with identical registration features at loading stations and alternately conveyed to an assembly station with a top mounted laser welder for welding the mask to panel rails. A lift assembly up loads the modules into the assembly station where they are registered with the same registration elements. Screen location on the panel is interrogated by panel module associated cameras that view spaced fiducial marks on the panel previously located with respect to the screen. Mask interrogation is also accomplished by a camera array. Early screen interrogation enables the mask to be preliminarily positioned very close to final positioning.

Abstract: An optical interrogation system has camera arrays useful for determining the locations of a plurality of apertures on a flat tension shadow mask and fiducial marks on a screened front panel of a CRT. The system determines the actual location of apertures or fiducial marks with respect to the cameras' field of view. By eliminating gray scaling, the processing only for light/dark transitions in single-bit binary valued pixels from each of the cameras in parallel, i.e., simultaneously, remarkable rapidity is obtained in the interrogation of widely spaced fields with minimal hardware. The system may also be used to interrogate mask support surfaces on the front panel prior to welding the mask thereto.
