Abstract: An electrode structure includes: a plurality of pixel electrodes arranged separately from each other; and a plurality of dielectric layers laminated in a first direction with respect to the plurality of pixel electrodes, in which the plurality of dielectric layers includes: a first dielectric layer that spreads over the plurality of pixel electrodes in a direction intersecting with the first direction; and a second dielectric layer that includes dielectric material having a refractive index higher than that of the first dielectric layer, sandwiches the first dielectric layer together with the plurality of pixel electrodes, and has a slit at a position overlapping space between pixel electrodes adjacent when viewed from the first direction.

Abstract: The object of the present invention is to provide a coating composition which can provide a coating film having excellent adhesion to a chromium thin film under various conditions, and sufficient scratch resistance, and the present invention provides a coating composition for a chromium thin film formed on a substrate, wherein the coating composition includes: an acrylic copolymer (A) having a phosphate group and a hydroxyl group other than a hydroxyl group in the phosphate group; isocyanate (B); and a metal chelate (C).

Abstract: A first dust recovering part is disposed upstream in an air inlet passage from a fire detecting part. The air flow is deflected in the first dust recovering part so as to cause the dust to drop to separate from the air and to be recovered in a recovery area of the first recovering part. Farther downstream from the first dust recovering part, a second dust recovering part is arranged having a filter for recovering dust in the air which has passed through the first dust recovering part. Thus, clogging of the filter is avoided and erroneous operations caused by dust are more reliably reduced. As a result, the reliability of the fire detecting apparatus is improved.

Abstract: A fire detector comprises a piezo-electric element attached to a vibrating portion which is part of a component constituting the detector. The component having the vibrating function may be a casing or an electrode or any other suitable member. The piezo-electric buzzer is thus incorporated in the detector to form a simple and compact fire detector with an alarm device.
