Abstract:
Two yokes of magnetic material are fixedly attached to opposite axial ends of a magnet which is revolvable about its axis with a revolving shaft, an alternating magnetic field generator is positioned in the magnetic field between the two yokes to generate alternating magnetic field with revolution of the shaft, and a magnetoelectric transducer is provided in the alternating field in order to generate a pulsating electrical signal indicative of the number of the shaft revolutions.
Abstract:
A conductive spacer having one end secured to an electron gun structure housed in the neck tube of a color picture tube makes contact, at the other end, to a conductive film coated on the inner wall surface of the envelope of the color picture tube. A portion of the conductive film making contact with the conductive spacer comprises a conductive frit glass film.
Abstract:
A circuit pattern to be inspected is imaged so that an image signal representing the circuit pattern to be inspected is produced. The image signal of the circuit pattern is compared with a reference circuit pattern image signal, wherein a part of the image signal discerned to be different from the latter is detected as a candidate defect, at a rate synchronized with the rate of imaging. A local image signal corresponding to each local image covering a region including every one of detected candidate defects is extracted and stored in a memory device. Thereafter, on the basis of the local image signal read out from the memory device, whether or not the candidate defect concerned is fatally harmful with regard to electrical conductivity is examined at a rate asynchronous with the imaging rate.
Abstract:
A display device includes: a first substrate and a second substrate which are located so that inner main surfaces thereof face each other; a liquid crystal layer located between the first substrate and the second substrate; a seal material located between the first substrate and the second substrate so as to surround the liquid crystal layer, the seal material bonding the first substrate and the second substrate to each other; an organic insulation film located in a seal formation area on the inner main surface of the second substrate, the organic insulation film having an opening section in the seal formation area; and an inorganic insulation film located to continue from an inside of the opening section to a surface of the organic insulation film through an inner wall surface of the opening section, the inorganic insulation film being directly covered with the seal material.
Abstract:
When fusing together a panel having a fluorescent film and a metallic reflective film, and a funnel with an electroconductive film in a baking furnace for manufacturing a cathode ray tube, oxygen containing air is forced into the furnace.
