Abstract: An oil hole penetrating through a partition wall of a pulley cover of a continuously variable transmission is formed in a direction perpendicular to an axis of the pulley cover. The pulley cover, having first and second hydraulic oil chambers through which a movable pulley half of a pulley of the continuously variable transmission is biased toward a fixed pulley half thereof, is manufactured in the step of machining a metal sheet. The manufacturing step includes a first step of press-forming the annular partition wall of the pulley cover, a second step of opening the oil hole in the partition wall, the oil hole allowing communication between the first and second hydraulic oil chambers, and a third step of press-forming the peripheral wall of the second hydraulic oil chamber at an outer side, in a radial direction, of the partition wall.

Abstract: To provide a novel biomarker that is useful for prediction of early onset of acute kidney injury, estimation of prognosis associated with a renal function, and differentiation of acute kidney injury. Furthermore, to provide use of the novel biomarker. Midkine is used as a biomarker. The determination of a possibility of the onset of acute kidney injury, estimation of prognosis associated with a renal function or differentiation of an acute kidney injury are carried out based on the detection result of the urinary midkine.

Abstract: Provided is a therapeutic method targeting midkine for treating mammalian kidney disorders, primary kidney disorders, hypertension that follows secondary kidney disorders such as diabetic nephropathy, and hypertension secondary to chronic kidney disease.

Abstract: The invention provides a ceramic conveyor belt assembly including a plurality of first conveyor belt parts, each comprising front and rear transverse bars and left and right longitudinal bars connecting the transverse bars, and pins located on the front and rear transverse bars and extending laterally therefrom. Further, there exists a plurality of second conveyor belt parts in the shape of a columnar member, each having a keyhole shaped so as to conform with the corresponding portion of the transverse bars. This ceramic conveyor belt is excellent in heat resistance and chemical resistance, unlikely to form rust and less likely to undergo loss in strength even at high temperature. In case some parts fail, they can be easily replaced by new parts.
