Abstract: The CPA-attached connector 1a includes a connector body 11 and a CPA member 12. The connector body 11 includes a temporary latch portion 112 for the CPA member 12, a full latch portion 113 which, before the mating with a mating connector, restricts full latch of the CPA member, and which, during the mating, cancels restriction of the full latch by the mating connector, and a hood portion 114 configured to cover, in a manner of a canopy, a portion of the CPA member 12 in the full latch state. The CPA member 12 includes a CPA body 121 and a finger rest portion 122 provided on the CPA body 121, a portion of the finger rest portion 122 being exposed from the hood portion 114 even in the full latch state, an inclined surface 122a being formed in the exposed portion to incline toward a central axis of the connector body 11 in accordance with a distance from the hood portion 114.

Abstract: A power generation device includes a filter holder that is a container filled with water and a filter member. The filter member is composed of porous glass in a form of a plate and arranged in the filter holder between a first space upstream from the filter member and a second space downstream from the filter member. The filter member allows hydrogen ions to pass therethrough more easily than hydroxide ions. The power generation device generates electric power based on a potential difference between the first space and the second space when a water flow from the first space toward the second space is produced in the filter member. The water flow flows along a direction of thickness of the filter member.

Abstract: In this power semiconductor module, a first lead frame and a second lead frame through which currents flow in opposite directions are arranged so as to overlap each other, whereby the internal inductance can be reduced. In a direction perpendicular to one main surface of a first metal wiring layer, each of the first lead frame and the second lead frame is provided so as not to overlap parts of end surfaces of the first metal wiring layer and a second metal wiring layer. Thus, in a manufacturing process for the power semiconductor module before sealing with sealing resin, it is possible to easily perform positioning between the lead frames and between the metal wiring layer and the lead frame, using the end surfaces, whereby the manufacturing process can be simplified.
