摘要:
A multi-usable thermal transfer ink sheet wherein on a foundation is provided a thermal transfer ink layer which is tranferable in portions in terms of the thickness thereof. To realize multi-printing even in an indirect thermal transfer method, the multi-usable thermal transfer ink sheet is characterized in that the thermal transfer ink layer contains as main ingredients thereof a wax compound having a polar group, and a pigment.
摘要:
In a thin solid electrolytic capacitor including a solid electrolytic capacitor element disposed on a substrate, the solid electrolytic capacitor element has an upper surface largely extending along the substrate as compared with a height dimension thereof from the substrate. A casing portion is at least partly made of a resin and surrounds the solid electrolytic capacitor element jointly with the substrate. The casing portion includes a non-adhesive member that is in contact with an upper surface of the solid electrolytic capacitor element, but is not adhesive to the solid electrolytic capacitor element.
摘要:
Anodized films are formed at both surfaces of an aluminum base and, at the center portion on each side of the aluminum base, a solid electrolyte layer of a conductive polymer, a graphite layer, and a metal layer are stacked in the order, thereby forming a rectangular cathode portion. An insulator layer is formed at the peripheries of four sides of the cathode portion and, further, an anode lead frame is provided at the peripheries of four sides of the upper insulator layer, thereby forming an anode portion. Openings are formed at four corners of the insulator layer or the anode portion, thereby establishing electrical connection between the cathode portions on both sides of the aluminum base. By setting the ratio of a total region, occupied by the openings, of the cathode portion to 25% or less, the ESL of a capacitor can be suppressed low even when the openings are provided.
