    Abstract: A thermal conductive mechanism for a battery pack made up of a stack of a plurality of sub-battery modules each of which includes a plurality of battery cells arrayed thereon. The sub-battery modules each has opposed major surfaces and are laid to overlap each other in a direction perpendicular to the major surfaces. The thermal conductive mechanism is equipped with plates provided one for each of the sub-battery modules. Each of the plates has a given number of the battery cells disposed thereon and also has heat transfer surfaces extending in a planar direction of the plate. The heat transfer surfaces are placed in one of direct and indirect contact with the given number of the battery cells to achieve transfer of heat therebetween, thereby equalizing the temperature in each of the battery cells and also minimizing a difference in temperature among the battery cells.

    Abstract: The spark plug has a configuration satisfying the relationships of B≧0.7A and 0.3 mm≦A≦0.6 mm, where B is an axial thickness along the central axis line Q of the weld portion formed between the base material electrode and the noble-metal chip, and A is an axial distance along the central axis line Q between the intersection points P3 and X. The intersection point P3 is a point at which a phantom axis line radially distant from the central axis line Q by D/2 (D being a diameter of the noble-metal chip) intersects with the boundary line between the weld portion and the noble-metal chip. The intersection point X is a point at which an extension of the contour line of the base material electrode in the vicinity of the weld portion intersects with a boundary line between the weld portion and the base material electrode.

    Abstract: An abnormality determination device for a secondary battery includes an internal-resistance calculation unit, a threshold memory unit, a capacity balance comparison unit, and an abnormality determination unit. The internal-resistance calculation unit detects an internal resistance in a negative-electrode reaction resistance dominant region in which a reaction resistance of a negative electrode is dominant in a charge and discharge reaction of the secondary battery. The threshold memory unit stores a capacity balance threshold used as a reference for determining abnormality in a balance between a capacity of a positive electrode and a capacity of the negative electrode in the secondary battery. The capacity balance comparison unit compares the internal resistance calculated by the internal-resistance calculation unit with the capacity balance threshold stored in the threshold memory unit. The abnormality determination unit determines abnormality in capacity balance in the secondary battery based on a comparison result from the capacity balance comparison unit.

    Abstract: A heat exchanger includes a core portion including a plurality of tubes, and header tanks located on opposite ends in the longitudinal direction of the plurality of tubes and communicate with the plurality of tubes. A first fluid flows through a first tank chamber and a first tube group of the plurality of tubes. A second fluid different in temperature range from the first fluid flows through a second tank chamber and a second tube group of the plurality of tubes connected to the second tank chamber. The heat exchanger includes a flow rate limiting portion. The flow rate limiting portion is configured to reduce a flow rate of the first fluid or the second fluid supplied to at least first one tube of the plurality of tubes from a boundary portion provided by the partition wall.

    Abstract: A laser welding method for coil wires includes welding two coil wires by irradiating a laser beam to an upper end edge of butted surfaces of side surfaces of tip end portions of the two coil wires. At this time, a molten pool is formed at the center of a welding portion on the upper end edge by scanning the laser beam in a plurality of continuous loop shapes from one or both welding end portions, and welding is performed to make the molten pool at the center portion of the welding portion greater in welding depth than other molten pools by controlling at least one among a movement pitch, a loop area, a laser scanning speed, and a laser power of loops of the laser beam.

    Abstract: A side slit of a core plate of a heat exchanger reaches a sealing surface. The core plate has a rib which is formed on a bottom plate across a protruding portion. The rib communicates to a cavity above the sealing surface. An end slit formed on an end wall of the core plate reaches the sealing surface. A first joining tab is formed between two end slits. The first joining tab is joined to a second joining tab on a reinforce plate. The side slit and the rib enable deformation of the core plate. The end slit enables deformation of the first joining tab in a tilting manner.
