A multilayer piezoelectric element has a laminate body in which a plurality of piezoelectric bodies and a plurality of internal electrodes are alternately laminated and sintered. The plurality of internal electrodes comprise a first electrode and a second electrode. The laminate body has an active portion in which the first electrode and the second electrode are arranged to overlap in a laminate direction of the laminate body, and inactive portions in which the first electrode and the second electrode are arranged not to overlap in the laminate direction of the laminate body. The inactive portions are provided on both sides of the active portion. The inactive portions are provided with a metal oxide layer made of a material having a melting point higher than a sintering temperature of the piezoelectric bodies and being soluble in the piezoelectric bodies.

The multilayer body consists of an alternate stack of a plurality of piezoelectric members and a plurality of internal electrodes. The first external electrode is electrically connected to predetermined internal electrodes. The second external electrode extends in a wave pattern along a stack direction of the multilayer body and is of flat plate shape. The first external electrode and the second external electrode are electrically and physically connected through a plurality of connections.

A first area and a second are formed in an image projected by a projector. A standard image plate is placed in a surface on which an image for the first area is projected. A standard image has been drawn on a standard image plate and is displayed in correct colors when white light is projected on the standard image plate. The projector projects white light as the image for the first area. An image for the second area is projected on a projecting surface. A user operates an operating section so that the image in the second area is closer to the standard image. A color correcting section corrects the colors of the image in the second area on the basis of information inputted to the operating section.
摘要:
The coating composition includes a methacrylic resin prepared by copolymerization of styrene or a substituted styrene (A), a methacrylic ester obtained from an alcohol having at least two carbon atoms and methacrylic acid (B), and an olefinic compound having at least one carboxylic group (C), in which the molar ratio thereof is 1:(0.05 to 44.5):(0.12 to 13). A metal sheet lubricated with the coating composition has superior characteristics of dissolution of the film in an alkaline solution, chemical processing, paint dryness, blocking resistance, corrosion resistance, stability of coating composition, and press formability (powdering resistance and galling resistance).
摘要:
The coated steel sheet is a zinc-based plated steel sheet which has a zinc phosphate-based coating containing magnesium thereon and a silicone resin coating containing a functional group which reacts with an organic substance on the surface of the zinc phosphate-based coating. The coated steel sheet has superior perforative corrosion resistance, paint adhesion, electrodesposition paintability, press formability, and weldability without using chromium and therefore is useful as an anti-corrosive steel sheet for automobile bodies.
