Abstract: An electrolytic capacitor includes an anode body that includes a porous body and a dielectric layer covering the porous body, and a solid electrolyte layer that covers the dielectric layer. The porous body has a first region located near an outer surface of the porous body, and a second region other than the first region. The first region is a region in which a distance from the outer surface of the porous body is shorter than 0.5D, where D is a shortest distance between the outer surface of the porous body and a center of the porous body. A filling proportion R2 of the solid electrolyte layer in the second region is less than a filling proportion R1 of the solid electrolyte layer in the first region. A ratio R2/R1 of the filling proportion R2 to the filling proportion R1 is less than or equal to 1/10.

Abstract: A camera mounting assembly includes a base member or plate for holding a camera and a side member or plate. In an exemplary embodiment, lower slots on the base plate or side slots on the side plate are gripped by a vertical support's quick-release mechanism to mount the camera in a landscape or portrait orientation, respectively, the camera being generally centered and evenly balanced over the support in either case. The side member is detachably fastened to the base member, which modular construction permits separately timed purchase of the base member and side member as allowed by the user's budget and further permits breakdown of the assembly for ease of transport. The side member may be generally L-shaped with a lower arm length less than the side arm length, which also facilitates transport. Other components may be detachably added such as a hand grip facilitating freehand shooting with the camera.

Abstract: A solid electrolytic capacitor containing a capacitor element is provided. The capacitor element contains an anode body that contains tantalum, a dielectric that overlies the anode body; and a solid electrolyte that overlies the dielectric. The solid electrolyte includes an intrinsically conductive polymer containing repeating thiophene units. Further, the capacitor exhibits a dielectric strength of about 0.6 volts per nanometer or more. The capacitor also exhibits a charge-discharge capacitance after being subjected to 3,000 cycles of a surge voltage and an initial capacitance prior to being subjected to the surge voltage, wherein the ratio of the charge-discharge capacitance to the initial capacitance is from about 0.75 to 1.
