Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable concave-convex pattern detector.
SOLUTION: The concave-convex pattern detector comprises a slant FOP 3 having an input end face 4 that an object surface comes in contact with and an output end face 5 roughly parallel to the input end face 4, an irradiation light source 10 disposed on the output end face 5 side of the slant FOP 3 for irradiating the output end face 5 with light, and a CCD camera 11 disposed on the output end face 5 side of the slant FOP 3 for detecting a concave-convex pattern based on the light emitted from the output end face 5. The optical axis Rf of an optical fiber 6 is slanted to form a first angle α less than 90° around one direction from the output end face 5 in a predetermined plane roughly perpendicular to the output end face 5. The irradiation light source 10 irradiates the output end face 5 with light from a direction forming a second angle β less than 90° around the other direction from the output end face 5 in the predetermined plane. The first angle α and the second angle β are set such that the light incident on a core 8 of the optical fiber 6 from the output end face 5 enters a clad 9.

Abstract: PURPOSE:To obtain protective glasses free from erroneous operation by equipping the glasses with an ultraviolet ray detection means for detecting ultraviolet rays having a predetermined wavelength or less to output the detection result and a light shield means for limiting the incidence of light to the eye of a wearer according to the output from the ultraviolet detection means. CONSTITUTION:Protective glasses 1 are constituted of a liquid crystal type light shield part 2 and an ultraviolet detection part 3 and ultraviolet detection elements 3a, 3b are provided to the ultraviolet detection part 3 and emit signals, for example, when light having a wavelength of 270nm or more is incident in predetermined quantity or more. Further, a filter 3c for shielding a part of light is provided to the front surface of the element 3b. When welding work is carried out, the ultraviolet detection elements 3a, 3b detect ultraviolet rays to generate detection signals and the application of voltage to liquid crystal films 2a, 2b is eliminated and the protective glasses 1 become the most light-impermeable state and an eye is not damaged. When ultraviolet rays generated from other worker are incident to an eye and the protective glasses 1 become a light shielding state, a pitch-dark dangerous state is developed. In this case, the ultraviolet rays incident to the ultraviolet detection element 3b are attenuated by the filter 3c and the element 3b detects no ultraviolet rays and ultraviolet rays are attenuated to a degree imparting no damage to an eye.

Abstract: PROBLEM TO BE SOLVED: To provide a X-ray tube with an electric insulation part extremely hard to break by making electric discharge to the electric insulation part extremely hard to cause.
SOLUTION: An electric resistance film 36 electrically connected to an enclosure body (a conductive part) 4 of a casing 2 of the X-ray tube 1 is applied to an outer face 10c of a bulb (the electric insulation part) 10 to stably suppress the breakage of the bulb 10 due to electric discharge. The electric resistance film 36 has one end electrically connected to the enclosure body 4 and the other end located inside the outer face 10c of the bulb 10. Thus, the insulating property of the bulb 10 is held even when the electric resistance film 36 is fixed thereto.
