A head 2 is hollow. The head 2 has a sole part 8. The sole part 8 has a groove forming part k1 having a recessed outer surface g1 and a protruding inner surface s1. The sole part 8 has a first groove forming part k1 and a second groove forming part k1. The first groove forming part k1 and the second groove forming part k1 have a front-back directional length. A distance between the first groove forming part k1 and the second groove forming part k1 in a toe-heel direction is wider toward a back of the head. Preferably, the first groove forming part k1 and the second groove forming part k1 exist on a back of a face surface 13. Preferably, the sole part 8 has a connecting groove part r1. The connecting groove part r1 is formed by connecting a front end of the first groove forming part k1 to a front end of the second groove forming part k1 with each other.

Deformation by camber recovery etc. due to non-uniform residual stress is suppressed, and occurrence of crack and burr is suppressed by improving press forming property of a roof side T-shaped portion, so that a reinforcing member having a predetermined shape accuracy is manufactured easily and inexpensively by pressing. A reinforcing member (12) is constructed by three members, i.e. an upper member (20), a lower member (22) and a central member (24). A tensile strength of the upper member (20) is selected lower than that of the central member (24), and is higher than that of the lower member (22). In comparison to a case where the upper member (20) and the central member (24) are constructed integrally by an ultra-high tensile steel plate, fluctuation of internally generated residual stress is made small. Shape accuracy is thereby improved by the reduced deforming amount due to camber recovery etc., thus press forming being facilitated. Also, a roof side T-shaped portion constructed by the upper member (20) is improved in the drawing property, and the door frame corner portions (30) and (32) are improved in the outer trimming property. Thus, the shape accuracy is improved, and yield and productivity is increased by suppression of crack generation.

A claw-pole electric generator has a circumferentially arranged permanent magnet, a ring-shaped coil, a yoke and a cover member. The yoke surrounds an external periphery of the coil. The yoke has a stator yoke portion and a core yoke portion. The stator yoke portion is disposed between the coil and the permanent magnet. The core yoke portion is magnetically linked to the stator yoke portion. The core yoke is disposed on the external periphery of the coil. The coil and the yoke are rotatably disposed in relation to the permanent magnet. The stator yoke portion includes a plurality of first and second yoke sections having a plurality of plate-shaped pieces in a stacked arrangement on opposite sides of the coil in an axial direction. The cover member covers at least part of an external peripheral surface of the yoke section.

The present invention provides an inexpensive metallic material for interconnects of solid-oxide fuel cells, a fuel cell using the metallic material, and a method for producing the metallic material having excellent oxidation resistance and spalling resistance of an oxide layer, high electrical conductivity, and a small difference in thermal expansion from an electrolyte. Specifically, 0.20 percent by mass or less of C, 0.02 to 1.0 percent by mass of Si, 2.0 percent by mass or less of Mn, 10 to 40 percent by mass of Cr, 0.03 to 5.0 percent by mass of Mo, 0.1 to 3.0 percent by mass of Nb, and at least one element selected from the group consisting of Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Zr, and Hf in a total of 1.0 percent by mass or less are added so as to satisfy 0.1≦Mo / Nb≦30, for decreasing the growth rate of the oxide layer and improving the spalling resistance.

A vehicle body structure in which a panel is reinforced by a pair of reinforcing members, and a connecting member is included. The pair of reinforcing members intersects with each other and the reinforcing members are provided along one surface of the panel. The connecting member is connected to both of the pair of reinforcing members in a portion where the pair of reinforcing members intersects with each other.

In a crankshaft of an in-line four-cylinder engine, an arm that is closest to a flywheel has a greater average thickness in a direction of the rotation axis of the crankshaft than those of other arms. Two of the arms that are coupled to both sides of the third journal from the flywheel each have a center of gravity closer to its own counterweight compared to the centers of gravity of the arms that face the two arms with corresponding crankpins in between. Accordingly, the rigidity against torsional deformation and the thickness of oil films on the journals are reliably maintained while suppressing increase in the weight of the entire crankshaft.

The invention discloses a water-in-oil type high-internal-phase Pickering emulsion as well as a preparation method and application thereof. The method comprises the following steps: dissolving and dispersing polyglycerol ricinoleate as an emulsifier and diglyceride into an oil phase; then slowly adding a water phase into the mixed oil phase at a constant speed and carrying out pre-mixing by utilizing a stirrer; then carrying out high-speed shearing emulsification on a crude emulsion; after homogenizing is finished, rapidly cooling the crude emulsion to room temperature by utilizing an ice-water bath to obtain the water-in-oil type high-internal-phase Pickering emulsion with the water phase volume percent of 75-85%. The emulsion has excellent plasticity and stability, low fat content and relatively high nutritional characteristics. According to the method disclosed by the invention, large-size equipment is not needed in a preparation process of the emulsion, so that the emulsion is environmentally friendly and has no pollution; the cost is low and complicated procedures are not needed; and the emulsion is easy to produce and can be used as a novel healthy functional ingredient to beapplied to a plurality of fields including foods, cosmetics and the like.

In a motorcycle-use power unit in which a clutch device arranged in a power transmission path between a crankshaft and a drive wheel is housed in a clutch chamber which is defined between a crankcase and a clutch cover joined to a side surface of the crankcase, the maintenance of the clutch control device can be easily performed while preventing a lowering of oil-pressure transmission efficiency between the clutch device and the clutch control device and preventing an increase in the weight of the motorcycle. A clutch control device performs a changeover of engagement and disengagement of a clutch device by controlling the oil pressure applied to the clutch device. Oil passages for connecting the clutch control device and the clutch device with each other are mounted on a clutch cover.
