Abstract: A composite oxide for exhaust gas purification catalysts, which comprises Ce, Bi, R and oxygen and satisfies 0<x?0.4 and 0<y<1.0 when the molar ratio of Ce, Bi and R of the oxide is represented as (1?x?y), x and Y respectively. The composite oxide has an X-ray diffraction peak corresponding to that of a fluorite structure. In the composite oxide, R contains one or two of Pr and Tb. The exhaust gas purification catalyst is favorable for a PM combustion catalyst.

Abstract: To provide a press-fit terminal with excellent connection reliability of which a plating surface is not scraped off when press-fitted into a through hole of a circuit board. Manufacture of the press-fit terminal for inserting into the conductive through hole of the circuit board includes the steps of forming an underplating layer including one or more plating layers on a surface of a terminal base of a connecting part of the press-fit terminal which comes into electrical contact with the through hole, forming an Sn plating layer on the top plating layer, and after the step of forming the Sn plating layer, conducting a reflow process of performing heat treatment to form an alloy layer of Sn and an underplating metal of the top plating layer on the underplating layer as well as make unalloyed Sn mixed in an outside layer of the alloy layer.

Abstract: A bulging wall portion, which forms a connector accommodation portion by bulging outward from a side wall, is formed in a cover plate portion of a cover. The bulging wall portion has an overhead wall formed such that it rises from the cover plate portion. A sloping wall is formed on the overhead wall such that roughly the center in the width direction of the connector accommodation portion serves as a vertex and the sloping wall slopes in downward gradients from the vertex toward both ends in the width direction. Water that flows down over the cover plate portion is caught by the overhead wall and flows downward along the sloping wall. The water is guided to both side faces on the outer sides in the width direction of the connector accommodation portion, so that it is drained off while avoiding the opening portions of the second through fourth connectors.

Abstract: In a mounting structure, a housing is supported while being raised from a printed circuit board by first molten solders provided between the housing and the printed circuit board, the supported housing is positioned such that terminals come to be located in the centers of lands by a self-alignment effect of second molten solders provided between the terminals and the lands and is fastened onto the printed circuit board by screws and the like with the first and second molten solders naturally cooled. The connector mounting structure is inexpensive and has a good durability and enables the miniaturization of a connector and a narrow arrangement of terminals.

Abstract: In the stationary side housing 10, there are provided four pin-type stationary electrodes 13 which are insulated from each other. In the movable side housing 20, there are provided movable electrodes 23 by which the stationary electrodes 13 can be electrically continued to each other when the movable electrodes 23 are engaged with the stationary electrodes 13. In the stationary side housing 10, there is provided a hood section 12A. In the movable side housing 20, there is provided a slit 25 for receiving the hood section 12A. Both the housings 10 and 20 are guided in the engaging direction of the movable electrode 23 with the stationary electrode 13 by the action of the hood section 12A and the slit 25. In the movable side housing 20, there is provided a movable plate 31 in the longitudinal direction. On this movable plate 31, there is provided an oblique groove 34, which is obliquely formed, engaging with the hood section 12A of the stationary side housing 10.
