Abstract: A solid electrolytic capacitor that includes a capacitor device having a valve action metal substrate with a main surface, a first end surface orthogonal to the main surface and disposed in an electrode extended direction, a second end surface orthogonal to the main surface and opposite the first main surface, and a side surface orthogonal to the main surface and the first end surface, and a porous layer on the main surface, a dielectric layer on at least part of a surface of the porous layer, a solid electrolyte layer on the dielectric layer, an electric conductor layer on the solid electrolyte layer, and an insulating material directly covering one of the first and second end surfaces of the valve action metal substrate.

Abstract: A solid electrolytic capacitor that includes a plurality of laminated units each including a valve action metal substrate including a porous layer on a surface thereof, a dielectric layer on a surface of the porous layer, and a solid electrolyte layer on the dielectric layer. A metal foil is between the laminated units. The units and the conductor layers are sealed with a coating resin. The valve action metal substrate has an anode section-side end surface directly connected to an anode outer electrode on the surface of the coating resin, and the metal foil is directly connected to a cathode outer electrode on the surface of the coating resin.

Abstract: A writing instrument such as a mechanical pencil is provided with a brush for eliminating static electricity. The instrument is composed of a barrel and a barrel cap attached to the barrel. A base portion of the brush is fixedly received in a cylindrical protector arranged within the barrel cap. A writing element operating mechanism is arranged to operably hold a writing element such as a lead so that the writing element can be selectively extended from and retracted into the barrel. A brush operating mechanism is also arranged to hold the protector movably along a central axis of the barrel cap so that the brush can be selectively extended from and retracted into the barrel cap. A cylindrical member may preferably be fixedly secured in a rear end of the barrel cap to guide the brush.

Abstract: A composition comprising a dispersion prepared by dispersing in an aqueous solution of a water-soluble high polymer, such as polysaccharides, a hydrophobic substance selected from the group consisting of hydrophobic solids and hydrophobic and non-volatile liquids, such as natural waxes, is applied as a coating to cover the outer surface of an agricultural product to form a coating membrane upon drying, which membrane has fine continuous microvoids by which the respiration of the agricultural product can be controllably suppressed thereby to effectively preserve the product over a long period.
