20100005414DISPLAY METHOD AND DISPLAY DEVICE - The composition mentioned hereinafter has been chosen to enable switching over the window targeted for manipulation by manipulating an arrow key, in case a subwindow which can be manipulated with a free cursor is present inside a main window which can be manipulated with a block cursor. In a state in which subwindow is focused during manipulation of main window, there is a switchover, by detection of lapse of a fixed time T, to manipulation of subwindow. In addition, in a state in which the free cursor is present in a border portion of subwindow during manipulation of subwindow, there is a switchover to main window as a result of detection of any one of: manipulation of key in the subwindow outward direction, pressing of key for a fixed time in the subwindow outward direction, and lapse of a fixed time T.01-07-2010

20100125125PROCESS FOR PRODUCING SOLID CATALYST COMPONENT PRECURSOR FOR OLEFIN POLYMERIZATION - A production process is provided for an olefin polymerization catalyst component precursor, including the steps of (I) adding an organomagnesium compound to a solution containing a solvent, a Si—O bond-containing silicon compound, and a defined titanium compound, under agitation, and continuing the agitation until a magnesium concentration in a liquid phase of a reaction mixture decreases to 9 ppm by weight or lower, and (II) solid-liquid separating the reaction mixture. A production process is also provided for an olefin polymerization catalyst component using the above precursor. Further, producing process is provided for an olefin polymerization catalyst using the above catalyst component. Still further, a production process is provided for an olefin polymer using the above catalyst.05-20-2010
20100174038PROCESS FOR PRODUCING SOLID CATALYST COMPONENT PRECURSOR FOR OLEFIN POLYMERIZATION - A production process is provided for an olefin polymerization catalyst component precursor, including the step of adding an organomagnesium compound to a solution containing a Si—O bond-containing silicon compound, a titanium compound represented by a defined formula, and a solvent, in an amount of 2.5 to 90 mol, per one liter of the solvent, of magnesium atoms contained in the organomagnesium compound added. Also provided are a production process of an olefin polymerization catalyst component using the above precursor; a production process of an olefin polymerization catalyst using the above catalyst component; and a production process of an olefin polymer using the above catalyst.07-08-2010
