Display device, method for driving the same, and electronic device using the display device and the method

An object is to reduce degradation of display quality due to variation in luminance of light-emitting elements, which is caused by variation in voltage because of wiring resistance of current supply lines, and to improve the display quality. In a voltage program period, a terminal serving as a source of a transistor for driving an EL element is electrically connected to a first wiring to which a first potential is supplied. In a light-emitting period, the terminal serving as the source of the driving transistor is electrically connected to a second wiring to which a second potential is supplied. Accordingly, voltage between a gate terminal and the source terminal of the driving transistor can be held without being adversely affected by wiring resistance of the current supply lines.

Robot joint space point-to-point movement trajectory planning method

A robot joint space point-to-point movement trajectory planning method. Joint space trajectory planning is performed according to the displacement of a robot from a start point to a target point during PTP movement and a limitation condition of a preset movement parameter physical quantity of each axis in a robot control system. An n-dimensional space is constructed by taking each axis of the robot as a vector, wherein n ≥2, and the movement parameter physical quantity of each axis of the robot is verified according to a vector relationship between the n axes of the robot, so that a trajectory planning curve of each axis of the robot satisfies the limitation condition of the preset movement parameter physical quantity. The method has a small amount of calculations and strong real-time performance, the movement curves are mild, the control time is optimal, and the algorithm execution effect is good.

Apparatus and method for image feature amount acquisition and medium recording image feature amount acquisition program, apparatus and method for image correction and medium recording image correcting program, and printing apparatus and method and medium recording printing program

As image data have come to be used in large volumes in recent years, statistical calculation processing of restored and sampled image data often suffers a shortage of memory capacity. In acquiring a feature amount of an image to automatically correct image data, where high-speed processing is preferred, it is judged whether the image data contain thumbnail data (step 108) and, when there are thumbnail data, “thumbnail” is set on a sampling flag (step 110) to secure a buffer for developing the thumbnail data (step 116 and step 120), the thumbnail data are developed in the buffer, and all the pixels are subjected to statistical calculation (step 126 through step 132), resulting in faster processing than where the original image data are developed and sampled.

Recovery of benzene and benzene derivatives from gasoline fractions and refinery streams

A process for the separation of the aromatic compounds benzene, toluene and xylene from an aromatics-containing reformate gasoline and pyrolysis gasoline or a coke-oven light oil or an aromatics-containing refinery stream, in which the aromatics are separated by an extractive distillation uses a novel solvent combination made up of the compounds n,n′-diformyl piperazine or 2,2-bis-(cyanoethyl)ether in a combination with n-formyl morpholine as a second solvent for extractive distillation so that the solvent combination obtained shows a higher selectivity with regard to the aromatics to be extracted so that a lower solvent load is required. The aromatics-containing feed mixture is first submitted to a pre-distillation so that the obtained fraction has a narrow boiling point range. This fraction is then submitted to an extractive distillation in a first column, in which an aromatics-lean head product of predominantly paraffinic hydrocarbons is obtained as well as an aromatics-enriched bottom product. The bottom product is passed to a second column in which an aromatics-rich raffinate is obtained by reducing the pressure or increasing the temperature so that the extracting solvent combination obtained as bottom product can be recycled into the process.
