Abstract: The object of the present invention is to provide a method which provides a diaminobiphenyl compound in a high yield and in a short period of time by a benzidine rearrangement reaction of a hydrazobenzene having a bulky substituent group at the meta position. Specifically, the present invention provides a method for preparing a diaminobiphenyl compound represented by the following formula (1): wherein, X1 and X2 are, independently of each other, a group selected from the group consisting of a trifluoromethyl group and, optionally fluorinated, isopropyl, isobutyl, sec-butyl, tert-butyl and neopentyl groups, comprising a step of subjecting a diphenylhydrazine compound represented by the following formula (2) wherein X1 and X2 are as defined above, to a benzidine rearrangement reaction in the presence of an organic solvent and an inorganic acid at a temperature of from ?70° C. to ?11° C. to obtain the diaminobiphenyl compound represented by the formula (1).

Abstract: A storage part stores beforehand, as an energy consumption graph, amounts of energy consumed by a vehicle traveling in both directions along road links on a map. A processing part traces a road link from a specified start point location peripherally, calculates, for each road node, a first and second integration values obtained by integrating amounts of energy in a direction moving away from the start point location on the energy consumption graph and in a direction moving toward the start point location on the energy consumption graph, and based on a relationship between the sum of the first integration value and the second integration value, and a given specified amount of energy for each road node, decides a round-trip driving range which is a range within which the vehicle is able to return to the start point location by using the specified amount of energy.

Abstract: An integrated information processing apparatus is provided with a display device and a generally transparent input tablet having an input surface placed on a display surface of the display device for outputting a pointing coordinate which is a coordinate on the input surface pointed by a user's finger or an indicator. The apparatus includes a circuit for determining an indication direction extended point coordinate from the pointing coordinate output by the input tablet and a predetermined value, and a display processing section for displaying a point on the display surface of the display device corresponding to the determined indication direction extended point coordinate so that it is distinguishably displayed on the display device.

Abstract: An input panel interface section is responsive to an input signal from an input panel to provide input coordinate data indicating an input position in a coordinate system used in the input panel. A converter converts the input coordinate data provided by the input panel interface section into display coordinate data. The display coordinate data is data in a coordinate system used for a display controller to determine a display position on a display. The display controller controls display output to the display by using the display coordinate data output by the coordinate converter. A CPU interface section controls access of a processor to the display controller, the input panel interface section, and the coordinate converter.

Abstract: The present invention relates to a document editing and a printing apparatus comprising a data processor such as a personal computer and a word processor, and more particularly to a method of correcting data to be printed. The object of the present invention is to provide a printed data correcting method capable of correcting an error in a printed document during printing without terminating the printing when such error is found. In order to achieve the object, according to the present invention, data involving printing is displayed to the user. Each data is stored which is indicative of whether data of a specified unit such as a character, a line or a page are printed or print-waiting such that the data stored as being print-waiting can be corrected. When the data stored as being already printed are corrected, only the page which contains the corrected data is reprinted.
