Abstract:
A failure detecting method for a solar power generation system having plural solar cell strings in each of which plural solar cell modules are connected to each other in series. Specifically, by comparing the current value of each of the solar cell modules or strings with the average current value per one module or string, calculated from the total current value of the entire solar cell modules or strings, one or more failure candidates can be detected with high precision.

The present invention provides a diode that does not deteriorate its function even if it is used in an environment where the temperature change is considerable, such as in a terminal box for solar cell panel that is placed outdoors. A diode of twin-chip-mounting type in which each chip has a lead foot for being joined to a common terminal plate, wherein said lead feet are electrically connected with each other in a region of each lead foot from each chip to a portion wherein each lead foot is joined. The electrical connection of the lead feet is preferably formed by integral molding with each lead foot.
Abstract:
A wire harness lead-out structure includes a body that includes a containing portion for receiving a wire harness and a corrugated tube covering the wire harness, a lid that is attached to the body to close an upper opening of the body, two completely-fixing ribs that are formed on the body and the lid respectively to be engaged in grooves of the corrugated tube to prevent a movement of the corrugated tube in an axial direction of the corrugated tube, and a provisionally-fixing rib that is formed in a single line on the opposed side walls of the body to be engaged in a single groove of the corrugated tube, and is disposed between the two completely-fixing ribs. The completely-fixing ribs are arranged in two lines corresponding to two grooves of the corrugated tube, the two grooves being both adjacent to the single groove corresponding to the provisionally-fixing rib. Each of the completely-fixing ribs on the body is formed into a U-shape along an inner periphery of the containing portion so that a distance between upper portions of the completely-fixing rib respectively formed on opposed side walls of the body is constant. A distance between portions of the provisionally-fixing rib formed on the opposed side walls is gradually decreased toward the upper opening of the body to prevent the corrugated tube from moving toward the upper opening of the body when the provisionally-fixing rib is engaged in the single groove of the corrugated tube.
Abstract:
Conductivity of a negative electrode is improved in an alkaline storage battery that uses as its negative electrode a hydrogen-absorbing alloy electrode employing a hydrogen-absorbing alloy containing at least a rare-earth element, nickel, magnesium, and aluminum, to sufficiently enhance the cycle life of the alkaline storage battery. The negative electrode of the alkaline storage battery uses a hydrogen-absorbing alloy electrode employing hydrogen-absorbing alloy particles containing at least a rare-earth element, nickel, magnesium, and aluminum. A surface layer is formed on the hydrogen-absorbing alloy particles, the surface layer having a weight ratio of aluminum to nickel less than that of the interior portion of the hydrogen-absorbing alloy. The weight ratio of aluminum to nickel in the surface layer is 0.015 or less.

A door latch apparatus for a vehicle includes a latch, a pawl, a motor, a release power transmitting mechanism, an active rotary member arranged in a standby area in a normal state, a driven rotation member rotating about a rotational shaft arranged in parallel with a rotational shaft of the active rotary member and away therefrom, a cam projection formed at the active rotary member, a cam groove formed at the driven rotation member and slidably engaging with the cam projection, the cam groove extending away from a reference line when the standby area is arranged close to one side of the rotation range and the active rotary member is positioned close to the one side of the rotation range, and a standby state detecting device detecting whether or not the active rotary member is arranged within the standby area based on a rotational position of the driven rotation member.
Abstract:
A device includes a latch of a door and rotates while engaging with a striker of a vehicle body; a pawl which is rotatable between a latched position to restrict a rotation of the latch and a unlatched position to permit the rotation of the latch; a motor; a release power transmitting unit which transmits a rotational power of the motor to the pawl and rotates the pawl from the latched position to the unlatched position. The device further includes a motor-side rotation board, a relay rotation board, and a pawl-side rotation board, which are connected to be integrally rotatable. The relay rotation board become movable to a power shutoff position by pressing operation though an operating hole formed in a door. In the power shutoff position, connecting between the three boards is released, and the motor-side rotation board and the pawl-side rotation board become individually rotatable.
