Abstract: A relay server computer adds control code to background contents to generate web data for display engagement, and sends the generated web data to every client computer. The control code becomes a controller by executed on the client. When an object such as image is pasted on the background contents displayed in an engaged fashion, the controller detects the event occurred by pasting, and sends the information indicating the event to the other clients via relay server. Consequently, the screen with the object being pasted is displayed in an engaged fashion among all clients. The object can be moved, modified, or deleted.

Abstract: A relay server obtains web data including a motion picture from a WWW server, and embeds control code composed of a script or bytecode in the obtained web data to generate web data for synchronization. The control code is sent to each of clients, and becomes a controller to control the browser in the same client. When one of the clients sends manipulating information indicating manipulation of the motion picture such as playback, stop, etc. to the relay server, the same relay server receive the manipulating information, and broadcast it to all of the clients including the sender. The controller of each client receives the manipulating information, and executes playback, stop, etc. in synchronization.

Abstract: Image data supplied to an image forming apparatus are converted into image data linearly correlated with the image density, and the image ratio is calculated by dividing the number of pixels in which the toner is deposited at the image formation of thus converted image data on a print medium, with a value obtained by multiplying the total pixel number corresponding to the size of the print medium with the number of gradation levels per pixel. Then the toner amount consumed in the image formation based on the entered image data is determined by multiplying the image ratio, the size of the print medium to be used and the toner amount consumed per unit area in a solid image formation.

Abstract: The present invention provides a lightweight and simply-configured watercraft of a jet-propulsive type that can maintain steering capability in a way adapted to forward movement and rearward movement of the watercraft even when throttle-close operation is performed and the amount of water ejected from a water jet pump is thereby reduced. During forward movement, when the throttle-close operation and steering operation of a steering handle are detected and an engine speed is between an idling speed and a predetermined engine speed, the engine speed is temporarily increased. During rearward movement, when the engine speed is the idling speed, the engine speed is temporarily increased in the same way. The engine speed is increased by changing a fuel injection timing of a fuel injection system, a fuel injection amount, and/or an ignition timing of an ignition system of the engine.

Abstract: Plural lines on a surface of a photosensitive body of an electrophotographic image formation apparatus are simultaneously scanned by plural laser beams for image formation. Each of a pair of semiconductor lasers 11a and 11b biased in an ON state is independently turned on. A surface potential of the photosensitive body in each case is measured by a measurement unit such as a surface potential sensor 30, a surface potential detection circuit 31 and an A/D conversion circuit 32. Based on the measured result, an operational current of each laser is determined by a CPU 33 such that the surface potential of the photosensitive body becomes a target-potential, e.g., 220V to 230V. An image pattern difficult to be influenced by the laser start characteristic and an image pattern easy to be influenced by the laser start characteristic are formed, and the formed image patterns are respectively measured so that the current supplied at no beam emission time is controlled according to the measured results.
