  • Publication number: 20160233519
    Abstract: Provided is an electrode catalyst that can exhibit sufficient performance, is suitable for mass production, and is suitable for reducing production costs, even when containing a relatively high concentration of chlorine. The electrode catalyst has a core-shell structure including a support; a core part that is formed on the support; and a shell part that is formed so as to cover at least one portion of the surface of the core part. The electrode catalyst concurrently fulfills conditions expressed by the following formulae (1) and (2): (X1/M)?1.2 . . . (1) (X2/M)?47.0 . . . (2) (in the formula (1) and the formula (2), M represents an amount of substance (number of atoms) of one or more constituent metal elements of the shell part, X1 represents an amount of substance (number of atoms) of bromine (Br), and X2 represents an amount of substance (number of atoms) of chlorine (Cl)).

  • Publication number: 20160226078
    Abstract: Provided is an electrode catalyst production method capable of obtaining, through an easy operation, an electrode catalyst whose chlorine (Cl) species content has been reliably and sufficiently reduced, even when using as an electrode catalyst raw material an electrode catalyst precursor containing a high concentration of chlorine. The method is to produce an electrode catalyst having a core-shell structure including a support, a core part formed on the support and a shell part formed to cover at least a part of a surface of the core part.

  • Patent number: 6431768
    Abstract: A digital camera having a camera body which includes a main surface and a lens surface substantially orthogonal to the main surface, a photographic lens of a photographic optical system positioned on the lense surface, and an optical viewfinder unit rotatably attached to the main surface such that the optical viewfinder unit is rotatable to a position substantially orthogonal to the main surface of the camera body and in a plane substantially parallel to said lens surface. An operation unit is positioned in the camera body such that operations buttons are arranged on the main surface of the camera body and, when the optical viewfinder unit is in a closed position, the operation buttons are substantially covered to protect against unintentional operation.

  • Patent number: 6210185
    Abstract: A connector connecting structure in which the manipulation of an operating member for effecting a fitting operation and a disconnecting operation can be effected by one motion. A pair of moving members, which are movable in a direction perpendicular to a connector-inserting direction, is mounted on a female connector. An operating member, which can be displaced between a preset position and a set position in accordance with the movement of the moving members, is mounted on the female connector. Guide grooves are formed in the moving members, and cam pins are formed on a male connector. The guide grooves and cam pins jointly constitute a cam unit.

  • Patent number: 6193530
    Abstract: A female connector is provided with a first moving member and a second moving member which are capable of moving independently of each other, and the female connector is further provided with an operating member which is rotatable. The operating member is provided with a pair of first cam grooves whose spiral groove shapes are formed oppositely, while the first and second moving members are provided with first cam pins which are respectively inserted in the pair of first cam grooves. As the operating member is rotated, the first and second moving members are moved in mutually opposite directions. The first and second moving members are each provided with a pair of second cam grooves whose angles of inclination are opposite, while a male connector is provided with second cam pins which are inserted in the second cam grooves.
