Abstract: A highly safe power storage system is provided. If n (n is an integer over or equal to three) secondary batteries are used in a vehicle such as an electric vehicle, a circuit configuration is used with which the condition of each secondary battery is monitored using an anomaly detection unit; and if an anomaly such as a micro-short circuit is detected, only the detected anomalous secondary battery is electrically separated from the charging system or the discharging system. At least one microcomputer monitors anomalies in n secondary batteries consecutively, selects the anomalous secondary battery or the detected secondary battery which causes an anomaly, and gives an instruction to bypass the secondary battery with each switch.

Abstract: A sheet feeding device that performs sheet feeding by feeding out and cutting a continuous medium includes a carrying part that carries the medium, a detection part that detects a leading edge of the medium and a length over which the medium has been carried, a trailing edge detection part that detects a trailing edge of the medium specified by a user; and a cutting part arranged between the detection part and the trailing edge detection part, and is capable of cutting the medium or forming cuts in the medium (a perforation process). When a minimum length of the medium that is carried by the carrying part is L2, a length from the detection part to the trailing edge detection part is L3, and a length of the medium that is specified by the user is L4, when the trailing edge of the medium is detected, and when L4<L3<L2+L4 is satisfied, the detection part detects a position is L4, and the cutting part forms cuts in the medium at the position.

Abstract: A label medium carrying device includes a medium carrying part that carries a separation label medium configured with a label member having an adhesive face and a peeling member superimposed on the adhesive face, a trailing edge peeling part that peels the trailing edge portion of the peeling member off the adhesive face in a trailing edge side of the separation label medium, and a folding trace forming part that forms a folding trace on the trailing edge portion of either the peeling member or the label member that is peeled off by the trailing edge peeling part.

Abstract: Adhesive agent for substrate of electroless plating characterized in comprising epoxy resin, synthetic rubber, and phenolic resin as main components, a hardener of the epoxy resin, inorganic filler having hydroxyl group, and solvent.The adhesive agent is hardened at relatively low temperature (about 150.degree. C.) in short period (within 30 minutes) without giving warp and distortion to the insulation substrate, and moreover its insulation resistance after hardening is high.The adhesive agent is preferable as an adhesive agent for a printed circuit board.
