摘要： A multi-layer ceramic electronic component includes a multi-layer unit and a side margin. The multi-layer unit includes ceramic layers laminated in a first direction, and internal electrodes disposed between the ceramic layers, positions of end portions of the internal electrodes in a second direction orthogonal to the first direction being aligned with one another within a range of 0.5 μm in the second direction. The side margin includes a center portion in the first direction and a third direction orthogonal to the first direction and the second direction, and corner portions in the first direction and the third direction, the corner portions having a lower porosity than a porosity of the center portion, the side margin covering the multi-layer unit from the second direction.

摘要： A elastically deformable string includes an outer layer and a core material placed inside the outer layer, wherein the outer layer has knob parts that are constituted by loosely woven outer layer yarns and elastically deformable, and link parts that are constituted by densely woven outer layer yarns and have a smaller diameter than the knob parts, wherein the loosely woven outer layer yarns are woven more loosely than are the densely woven outer layer using same yarns, and the core material is constituted by a stretchable string and placed inside the knob parts in a slackened and/or meandering state. The elastically deformable string is suitable for shoes, for example, as a shoelace which does not require knots.

摘要： A multilayer piezoelectric element includes a ceramic base body, a pair of external electrodes, multiple internal electrodes, and surface electrodes. The ceramic base body is formed by a piezoelectric ceramic. The pair of external electrodes cover a pair of end faces. The multiple internal electrodes are stacked inside the ceramic base body along a thickness direction crossing at right angles with a longitudinal direction, and connected alternately to the pair of external electrodes in the thickness direction. The surface electrodes are provided on a pair of principal faces, respectively, and are each connected to the external electrode different from the one to which the internal electrode adjacent in the thickness direction is connected. The pair of external electrodes have a higher porosity than the surface electrodes.

摘要： Clear inks are prone to heat-induced micro-gelling that can cause their storage stability to drop, and micro-gelling may also occur in clear inks with the passage of time, in which case their inkjet discharge property may drop. As a solution, a photocurable clear ink composition for inkjet printing is provided, which contains a photopolymerizable compound, a photopolymerization initiator, and an inorganic filler of 1 to 200 nm in average grain size accounting for 0.05 to 5.0 percent by mass in the composition, and whose visible light transmission factor is 30% or higher.

摘要： In an exemplary embodiment, an internal combustion engine, in which a valve is opened and closed when a piston reciprocates in a cylinder, has a configuration to perform repeatedly the following combined strokes: an intake stroke→a compression stroke→a combustion stroke→an exhaust stroke in a four-cycle internal combustion engine are combined with an intake and compression stroke→a combustion and exhaust stroke in a two-cycle internal combustion engine. The internal combustion engine can reduce pumping loss in a six-cycle internal combustion engine and increase the output.

摘要： An object of the present invention is to provide a drinking dramatization glass that is lightweight and allows images to be projected on the side face of the glass by changing their aspect ratio according to the size of the glass.
The drinking dramatization glass 1 comprises: a glass body 10 being a bottomed cylinder with a top opening 11 and having, on its side face, a flat part 20 and a curved part 30, both made of a transparent material; and a fixing mechanism 40 for fixing an image display device 80 on the flat part 20 in such a way that its image display surface 81 faces the flat part 20; wherein such drinking dramatization glass is characterized in that: the curved part 30 has, on the side contacted by a drink L filled in the glass body 10, a curved surface 31 that curves along the curved part 30; the curved surface 31 has radii of curvature R that, when an image 82 projected on the image display surface 81 is viewed from the exterior side of the glass body 10 through the drink L and curved part 30, allows for viewing of a virtual image 83 which is an enlarged version of the image 82; and the radius of curvature in the vertical direction RV, and the radius of curvature in the horizontal direction RH, of the curved surface 31, are different.
