Abstract: A bone plate including a long-plate-shaped main section to be disposed on a side surface of a diaphysis, a transverse section to be disposed on the side surface of an epiphysis, a coupling section coupling the transverse section and the main section to each other. The main section is twisted relative to the transverse section around an axis parallel to a longitudinal axis of the main section. when the bone plate is viewed in a transverse direction of the main section, the bone plate has a shape in conformity to the shin bone such that the coupling section is inclined relative to a longitudinal direction of the main section and the main section and the transverse section are bent to have a cranked shape in which the main section and the transverse section are offset relative to each other in a thickness direction of the bone plate.

Abstract: In order to apply, with a simple and easy means, proper pressure between bone segments spaced apart as a result of osteotomy or a bone fracture, without lowering the fixing force at the screw meshing portion, without increasing a dead space, and without increasing the thickness of the plate, the present invention provides a bone plate having an upper face, which is to be in contact with bone, a lower face, which is to be in contact with the bone, and a plurality of holes arranged to receive bone screws and connecting the upper face and the lower face. In at least one of the holes, a portion of an edge, on the upper face, of the hole is formed so as to be raised in the form of a protrusion higher than the upper face around the hole.

Abstract: To provide a fuel-efficient lubricating oil composition, particularly suitable for internal combustion engines, which has a reduced shear viscosity in an intermediate temperature range from 80 to 100° C., an effective temperature range for reducing fuel consumption. The present invention provides a lubricating oil composition comprising a base oil incorporated with a viscosity index improver, wherein the viscosity index improver has a peak area at a chemical shift between 3.4 and 3.7 ppm in a spectral pattern observed by nuclear magnetic resonance analysis (1H-NMR) accounts for 5% or more of the total peak area.

Abstract: In the steam reforming catalyst for hydrocarbon according to the present invention, catalyst metal is supported on or in the surface layer of a zirconia carrier containing yttria and having a crystal structure primarily consisting of tetragonal system or tetragonal and cubic systems. Compared with conventional steam reforming catalyst, it has higher reaction efficiency and suppresses carbon deposition extensively even when steam/carbon ratio is low and exhibits higher hydrogen generation efficiency and higher catalyst strength. Particularly, it is suitable as a catalyst for internal reforming type fuel cell.In the steam reforming catalyst of hydrocarbon of this invention, metal catalyst can be effectively utilized by supporting metal catalyst only on surface layer of zirconia carrier.
