Abstract: A traveling lane recognition apparatus includes a camera and a controller. The controller recognizes a linear marking position where a linear marking exists in each of detection target images, repeatedly performs image detection processing for detecting a white line or a blank at a linear marking position in each of detection target images corresponding to captured images, in an order of capturing time points of the captured images. The controller is configured to recognize a lane in which the vehicle is traveling among the plurality of lanes on the street based on a positional relationship between a solid lane line detected by the lane line detection and the vehicle and a positional relationship between the broken lane line detected by the lane line detection and the vehicle.

Abstract: A method of synthesizing a hyperbranched polymer by living radical polymerization of a monomer in the presence of a metal catalyst includes at least adding a compound or setting the amount of the monomer in the living radical polymerization. The compound added is at least a compound represented by R1-A or a compound represented by R2—B—R3, where R1 denotes hydrogen, an alkyl group (1-10 carbons), aryl group (1-10 carbons), or aralkyl group (7-10 carbons), A denotes a cyano group, hydroxyl group, or nitro group, R2 and R3 denote hydrogen, alkyl groups (1-10 carbons), aryl groups (6-10 carbons), aralkyl groups (7-10 carbons), or dialkylamino groups (2-10 carbons), and B denotes a carbonyl group or sulfonyl group. Setting of the monomer amount includes setting the amount of monomer to be mixed into a reaction system at one mixing to be less than the total monomer to be mixed with the reaction system.

Abstract: A hyperbranched polymer synthesizing method employs living radical polymerization of a monomer in the presence of a metal catalyst.

Abstract: The present invention provides a hyperbranched polymer that is capable of being used as a polymer material for nanofabrication including lithography, has enhanced dry etching resistance, sensitivity and surface smoothness, has a core shell structure and has an acid degradable repeating unit of tert-butyl vinylbenzoate ester in a shell portion, and a resist composition containing the hyperbranched polymer.
