Abstract: When industrially separating and purifying poly-3-hydroxyalkanoic acid produced by a microorganism, to obtain poly-3-hydroxyalkanoic acid particles having an arbitrary volume mean particle diameter with favorable productivity and with decreased amount of an organic solvent used is enabled while decreasing contaminants derived from constitutive components of cellular bodies. According to the present invention, aggregated matter of poly-3-hydroxyalkanoic acid is obtained by adjusting the amount of organic nitrogen in an aqueous suspension containing poly-3-hydroxyalkanoic acid to not greater than 1,500 ppm per weight of poly-3-hydroxyalkanoic acid; and thereafter allowing poly-3-hydroxyalkanoic acid to be aggregated in the aqueous suspension.

Abstract: The present invention has its object to provide a process for producing a vinyl polymer which can provide a vinyl polymer in such form that a polymerization catalyst is effectively removed from that. The present invention relates to a process for producing a vinyl polymer wherein a vinyl polymer at the time of completion of the polymerization is treated with oxygen in the presence of a polar solvent. More preferably, the present invention relates to a process for bringing a polymer added with a polar solvent having a relative dielectric constant at 20° C. of not lower than 10 into contact with mixed gases of oxygen and an inert gas such as nitrogen with an oxygen concentration below the explosion limit oxygen concentration of this solvent as in the state of occurrence as a pure component.

Abstract: The present invention relates to a method for producing a vinyl polymer retaining the ability for atom transfer radical polymerization, a method for reliably producing a vinyl polymer having terminal functional groups, a vinyl polymer having functional groups prepared by these methods, and a curable composition comprising the polymer. A vinyl polymer having terminal functional groups can be reliably produced through the steps of preparing a vinyl polymer by atom transfer radical polymerization of a vinyl monomer in a polymerization solvent in the presence of a polymerization initiator and a transition metal complex functioning as a polymerization catalyst, removing the polymerization solvent and the vinyl monomer while the ability for atom transfer radical polymerization is maintained, and supplying a functional-group-introducing agent having a low polymerizability to introduce a functional group to a polymer terminus.

Abstract: A navigation device performs navigation services for users and displays a navigation image. The navigation device is divided into the following four modules: an application unit for performing navigation services based on information from an external unit; an application control unit for controlling the application unit according to an internal state of the navigation device; a screen control unit for controlling display of the navigation image according to an instruction from the application unit; and a screen display unit for displaying the navigation image according to an instruction from the screen control unit.

Abstract: There is provided a purification process for dimethoxymethylsilane in which a mixture containing dimethoxymethylsilane and methanol is subjected to a first distillation step in which the mixture is distilled in the presence of methyl formate or methoxytrimethylsilane so that a distillate fraction containing methanol and methyl formate or methoxytrimethylsilane is distilled off and a balance fraction containing dimethoxymethylsilane and methanol is discharged, the amount of methanol in the balance fraction being substantially reduced relative to that of the mixture.
