Title: Radio wave measuring method and system using plural antennas
Inventor: WAKINAKA YOSHITAKA
IPC: H04B17/364
Filed: 2001-02-06
Abstract: PROBLEM TO BE SOLVED: To obtain a radio wave measuring method and system using a plurality of antennas whereby failures caused by reflected waves of radio waves can be suppressed. SOLUTION: An applicable point (a point receiving unnecessary reflected waves) is searched while the measuring system is moved (100). When a receiving level of radio waves exceeds a permissible range (denied in 102 and 104), reflected waves are extracted for a plurality of antennas having different azimuths after domain is measured (108, 110). Subsequently, a propagating path of radio waves to a measured part is geometrically analyzed by ray tracing (112), a propagation path is specified from the measurement result and the analysis result (114, 116), and a laser beam is emitted to a reflected part on the propagation path of the analysis result (118).

Title: Method of printing
Inventor: KOJIMA TAKESHI
IPC: B41J21/00
Filed: 2001-02-20
Abstract: PROBLEM TO BE SOLVED: To improve the appearance of the result of printing without wasting printing media. SOLUTION: The number of lines on a prescribed page is checked, and if the number is smaller than a previously set value, the image drawing region of additional lines is calculated for drawing the image data of the prescribed page. An enlarged image drawing region is set based on the image drawing region, and the image data are drawn in the enlarged image drawing region. The image data drawn in the enlarged image drawing region are compressed, and the compressed image data are transmitted to the mechanical part of a printer. In the method, if the number of lines on the prescribed page is smaller than the previously set value, lines in the number of lines on the prescribed page are evenly divided among pages up to the previous page. Therefore, printing sheets will not be wasted, and there will not be a large blank on the sheet of the prescribed page, so that the appearance of the result of printing can be improved.
