摘要:
A roll stand for a rolling mill has a housing with a through opening. The housing rotatably supports a pair of roll shafts, at least one of which is journalled for rotation in the eccentric bores of interconnected sleeves. The roll shafts carry work rolls positioned in the through opening to define a roll pass therebetween. An adjustment mechanism is axially engageable with one of the interconnected sleeves to rotate both sleeves and thereby adjust the parting between the work rolls. The adjustment mechanism is contained in a module which is separably connected to the housing.

Wind power turbines are largely divided into vertical axis type wind power turbines and propeller type (horizontal axis type) wind power turbines. The present invention discloses a vertical axis type wind power turbine. The airfoil of blades in this vertical axis type wind power turbine is formed in such manner that, denoting a proper position on the airfoil chord line as a camber reversing position, a camber having a downward convex curvature is given between said position and a leading edge and a camber having an upward convex curvature is given between said position and a trailing edge so as to be a mean line and a rational thickness distribution is given to this mean line. This vertical axis type wind power turbine is formed by keeping the spanwise direction of the above mentioned blade parallel with a vertical rotary axis and fitting a plurality of blades at regular intervals at a distance to the vertical rotary axis through respective supporting arms.

Wind turbines are largely divided into vertical axis wind turbines and propeller (horizontal axis) wind turbines. The present invention discloses a vertical axis high speed wind turbine provided with rotational speed control systems. This vertical axis wind turbine is formed by having blades of a proper airfoil fitted to respective supporting arms provided radially from a vertical rotating shaft by keeping the blade span-wise direction in parallel with the shaft and being provided with aerodynamic control elements operating manually or automatically to control the rotational speed of the turbine.

摘要:
An electrode for a lithium secondary battery includes a thin film of an active material having a first phase that reacts with Li dominantly and a second phase that reacts less readily with Li than the first phase and exists at least before initial-cycle charging and after discharging in each cycle following the initial cycle. A surface of the current collector has an arithmetical mean roughness Ra of 0.1 μm or greater. A surface of the thin film has irregularities formed corresponding to the irregularities of the current collector surface. By the charging and discharging in the initial cycle and thereafter, gaps form along the thin-film thickness on lines connecting valleys in the thin-film surface irregularities and valleys in the current-collector surface irregularities, and the thin film is divided into columnar or insular structures by the gaps.
