Abstract: A headset includes: a hollow housing (10) to be worn at an ear of a user; a cylindrical ear canal insertion part (12) that is a portion of the housing (10), and that is provided at a portion of the housing (10) at a side of an ear canal; a driver (14) for signal output, provided at an interior of the housing (10); a microphone (18) provided so as to collect a signal propagating at a second hollow part (16A), extending from inside an ear canal insertion part (12) and different from a first hollow part (12A) inside the ear canal insertion part (12), through which a signal output from the driver (14) propagates; and a computation unit (22) configured to measure a temperature inside the ear canal based on a collected signal collected by the microphone (18) at a time when a measurement signal is output from the driver (14).

Abstract: The present technique provides an electronic device, such as a flexible EL display device, including: first barrier film including a laminate of inorganic film including an inorganic material and polymer film including a polymer material; second barrier film including a laminate of inorganic film including an inorganic material and polymer film including a polymer material; and thin film transistor array device and light emitter both sealed with first and second barrier films. Polymer films each contain at least one type of nano fine particles selected from silica particles, Fe-based particles, montmorillonite particles, silica-coated particles, and zeolite particles, dispersed in the polymer material.

Abstract: A forming method of a protective film made of oxide containing any one of calcium oxide (CaO), strontium oxide (SrO) and barium oxide (BaO) and having a higher band gap than that of magnesium oxide (MgO) (higher than 7.9 eV) is provided. By adjusting a time constant of a protective film to a predetermined value or larger, the voltage drop time is adjusted so as to be usable for a plasma display panel. At this time, the time constant ?(=C×R) defined by the discharge capacitance C and the protective film resistance R is referenced.

Abstract: A discharge is initiated in a discharge space defined between the front glass substrate and the back glass substrate, whereby vacuum ultraviolet light is generated from a discharge gas filling the discharge space and excite phosphor layers. Each of the phosphor layers is formed of a firs phosphor having a resistance to an Xe resonance line, and absorbing the Xe resonance line and ultraviolet light in a longer wavelength range than the Xe resonance line and the Xe molecular beam but allowing the Xe molecular beam to pass through, and a second phosphor absorbing the Xe resonance line and the Xe molecular beam and generating ultraviolet light in a longer wavelength range than the Xe resonance line and the Xe molecular beam.

Abstract: A phosphor layer is provided on a back glass substrate placed opposite a front glass substrate with a discharge space in between, and formed in a double-layer structure consisting of a first phosphor layer and a second phosphor layer having its surface covered by the first phosphor layer. The first phosphor layer is formed of materials that permit the passing-through of a xenon molecular beam but absorb a xenon resonance line in the vacuum ultraviolet light generated from a discharge gas by means of a discharge, and have a higher resistance to the resonance line than that of the second phosphor layer. The second phosphor layer is formed of materials that have, as compared with the first phosphor layer, a higher light-emission brightness based on the xenon molecular beam in the vacuum ultraviolet light generated from the discharge gas by means of the discharge.
