Abstract: In a cleaning device, a signal processing circuit determines that a foreign substance has adhered to a surface of a protection cover based on at least two pieces of information among a change amount of a resonant frequency when a vibration portion is driven at a first voltage, a change amount of a current value relating to an impedance detected by an impedance detector, and a temporal change of an image captured by an imaging portion, and cleans the surface of the protection cover by controlling the vibration portion in accordance with the determination.

Abstract: A solid electrolytic capacitor includes a capacitor element, an anode terminal and a cathode terminal. The capacitor element includes an anode body, a dielectric layer, a solid electrolytic layer, a conductive layer and an anode lead wire. The anode lead wire is partially embedded in the anode body and extends in a horizontal direction from the anode body. The anode lead wire has a thicker portion and a thinner portion. The thinner portion is positioned closer to the anode body than the thicker portion is in the horizontal direction. The anode terminal at least has a first end, a second end and an overlapping portion. The anode terminal is connected to the anode lead wire under a state where the first end of the anode terminal is positioned on the thinner portion while the overlapping portion of the anode terminal overlaps with the thicker portion.

Abstract: A solid electrolytic capacitor includes a capacitor element, an outer anode terminal, an outer cathode terminal and an outer mold. The capacitor element has an anode lead wire, an anode body and a cathode layer. The capacitor element has an upper surface and a lower surface in an up-down direction. The outer cathode terminal and the outer anode terminal are positioned away from each other in a predetermined direction perpendicular to the up-down direction. The outer cathode terminal has an upper portion, a lower portion and a connecting portion. One of the upper portion and the lower portion is longer than a remaining one of the upper portion and the lower portion in the predetermined direction. The outer mold covers the capacitor element so that each of the outer anode terminal and the outer cathode terminal is partially exposed to an outside of the solid electrolytic capacitor.

Abstract: A capacitor has stacking capacitor elements, each of which contains a conductor plate, a first band being an insulator and disposed around the plate, a second band being an insulator and disposed around the plate so as to be substantially parallel to the first band, an insulating coating covering a region sandwiched between the first and second bands, a cathode layer formed on the insulating coating, and an anode containing the plate and formed on an outer side of at least one of the first and second bands. The cathode layers are elctrically connected to each other through paths each connecting in series the facing two cathode layers of the adjacent two elements and path(s) connecting in parallel the cathode layers to each other, and the anodes are electrically connected to each other through path(s) connecting in parallel the anodes to each other.

Abstract: A surface-mount capacitor includes a multilayer capacitor structure formed by laminating plate-like capacitor elements each having anode lead portions at opposite ends thereof and a cathode portion at the center, an anode terminal connected to each anode lead portion via a strip-like plate, and a cathode terminal connected to the cathode portion. The anode and the cathode terminals and have a flat shape and are formed on a common plane as a substrate-mounted surface. A mold resin case has a bottom portion filling a gap between the anode and the cathode terminals and mechanically connecting the anode and the cathode terminals and sidewalls substantially perpendicular to the substrate-mounted surface. The anode and the cathode terminals have upper surfaces exposed on an inner bottom surface of the mold resin case to be connected to the anode lead portions and the cathode portion.
