Title: News distribution system utilizing internet
Inventor: DENPO YOSHIYUKI
IPC: H04L12/70
Filed: 2001-02-15
Abstract: PROBLEM TO BE SOLVED: To solve such problems that, in electronic news comprising only texts and images, a conventional newspaper which uses paper as medium has more information amount than an electronic newspaper, a conventional technology which distributes the news by an electronic mail or a homepage increases the stress of a reader when large data including voice and animation is distributed, and, naturally, the newspaper cannot be read unless the fonts of the newspaper to be read are not installed beforehand.

Title: Transmission power control system and its method, and base station used for the same
Inventor: HIGASHIYAMA AKIHIRO
IPC: H04W52/04
Filed: 2001-03-29
Abstract: PROBLEM TO BE SOLVED: To conduct transmission power control with high accuracy without a delay and the need for increasing the circuit scale.

Title: Gravure printing method and gravure printing machine
Inventor: ICHIHARA TOSHIAKI
IPC: B41F31/02
Filed: 2001-04-02
Abstract: PROBLEM TO BE SOLVED: To prevent the clogging of a printing plate due to the dying of an ink from occurring, even when the ink is of such a type that it contains a solvent having high evaporation rate. SOLUTION: This gravure printing method comprises the steps to transfer the ink to the plate face of a plate cylinder 1 from an ink pan 4 to perform an inking process, then scrape off an excess ink from the plate face with the help of a doctor 3 and transfer the ink clogged in the cells of the plate face to the surface of a web 5 passing through a space between the plate cylinder 1 and an impression cylinder 2 to perform the printing or coating process. In this method, the concentration of the solvent on the plate face is kept at a constant level by airtightly closing the part of the plate face in a process from inking to transfer.  Even when the ink containing the solvent having high evaporation rate is used, it is possible to control the concentration of the solvent on the plate face so that no difference of the evaporation rate of the ink on the plate face occurs depending upon a printing direction or the variable density of a surrounding pictorial design. Thus, no clogging of the printing plate due to the drying of the ink occurs and consequently the keeping of a printing quality on a constant level is always achieved.
