A conductive film includes a layer 1 formed by a conductive material 1 that includes a polymer material 1 containing any of (1) an amine and an epoxy resin (where the epoxy resin and the amine are mixed in a ratio of 1.0 or more in terms of the ratio of the number of active hydrogen atoms in the amine with respect to the number of functional groups in the epoxy resin), (2) a phenoxy resin and an epoxy resin, (3) a saturated hydrocarbon polymer having a hydroxyl group, and (4) a curable resin and an elastomer and conductive particles 1. The conductive film has excellent stability in an equilibrium potential environment in a negative electrode and low electric resistance per unit area in the thickness direction. A multilayer conductive film including the conductive film achieves excellent interlayer adhesion, and using them as a current collector enables the production of a battery satisfying both weight reduction and durability.

A current collector for a secondary battery (1) of the present invention includes a resin layer (2) having electrical conductivity, and an ion barrier layer (3) provided on the surface of the resin layer (2). The ion barrier layer (3) contains ion trapping particles (6) in which metal compounds (5) are provided on the surfaces of metal containing particles (4). The ion trapping particles (6) are continuously provided from an interface (7) between the resin layer (2) and the ion barrier layer (3) toward a surface (3a) of the ion barrier layer (3). Thus, the ion barrier layer (3) prevents from the entry of ions, so that the ion adsorption in the current collector (1) can be decreased.

According to an embodiment, a control device includes a detecting unit, a communication unit, and a control unit. The detecting unit detects that a power-supplied device is connected to a power supply line relaying supply of power. The communication unit receives consumer authentication information including consumer identification information for identifying a consumer from a communication device when it is detected that the power-supplied device is connected to the power supply line, transmits the consumer authentication information to a first server, receives power-supply-availability determination information representing whether supply of power to the power-supplied device is possible or not, from the first server, and transmits power measurement information representing power supplied to the power-supplied device through the power supply line and the consumer identification information to a second server. The control unit supplies power to the power-supplied device when the power-supply-availability determination information represents that supply of power is possible.

According to one embodiment, a node that is a root node of a network forming a directed acyclic graph topology, which is composed of plural nodes including the node serving as the root node and having a parent-child relationship among nodes of adjacent hierarchies, includes a generating unit, an encrypting unit, and a transmitting unit. The generating unit generates a group key, and a list indicating a first node to which a distribution of the group key is inhibited. The encrypting unit encrypts the group key so as to be capable of being decrypted by a first child node other than the first node out of the child nodes of the root node. The transmitting unit transmits a first message, including an encrypted group key, which is the group key that is encrypted with respect to the first child node, and the list.

A wireless mesh network includes a plurality of nodes to which a device key is assigned. The device key belongs to one of a plurality of groups. In a root node, a correspondence relationship between the nodes and the device key thereof, and a correspondence relationship between past join nodes and a device key thereof, are stored. When a new node in the wireless mesh network is detected as a past join node, the device key assigned to the past join node is assigned to the new node again. When the new node is not the past join node, a new device key is assigned to the new node. A cipher text is generated by encrypting a message using device keys assigned to the nodes and the new node. If the number of groups to which the device keys belong is fewer, a size of the cipher text is smaller.

A collector for bipolar lithium ion secondary batteries comprises a first conductive layer that is obtained by adding a conductive filler to a base that contains an imide group-containing resin, and a second conductive layer that has a function of blocking lithium ions. The second conductive layer comprises a blocking resin layer that is obtained by adding a conductive filler to a base that contains a resin which contains no imide group, and a metal layer. This collector for bipolar lithium ion secondary batteries is used in such a manner that the first conductive layer is on the positive electrode active material layer side with respect to the second conductive layer.

An image forming apparatus includes a raster image data generating unit, a halftone image data generating unit, a size control unit, an image forming unit and a flash fixing unit. The raster image data generating unit generates raster image data of a plurality of color components from document data. The halftone image data generating unit generates halftone image data from the raster image data. The size control unit controls minimum halftone dot sizes of the halftone image data. The image forming unit forms color toner images to be fixed on a recording medium using color toners corresponding to the plurality of color components, based on the halftone image data whose minimum halftone dot sizes are controlled by the size control unit. The flash fixing unit emits flash light from a flash light source to the recording medium to fix the color toner images transferred onto the recording medium.

Disclosed is a portable terminal device, which has a reduced thickness, while ensuring a strength with which a display unit can be excellently held. In the device (100), the flat-board-like display unit (200) provided with a display drive section (213) that drives a liquid crystal display section (211) is attached to a first case (110) with a metal rear plate (160) therebetween. The rear plate (160) is provided with a reinforcing section (180), which is formed by folding back one plate end portion, which has a predetermined width, a plurality of times into a roll-shape on the rear surface side of the rear plate (160). The reinforcing section (180) is disposed at a position that includes the horizontal projection area of the display drive section (213), and prevents stress from concentrating on the display drive section (213) by reinforcing the display drive section (213).
