Title: Method for forming image and method for forming lithographic printing plate
Inventor: URANO TOSHIYOSHI
IPC: B41J2/14
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To form high-resolution images as high speeds by projecting a laser light to a side face of a thin tube passing the laser light and storing ink containing a photothermal conversion substance, scattering the ink from a leading end of the thin tube, transferring the ink on an image-receiving body and forming an ink image on the image-receiving body. SOLUTION: A laser light is projected to a side face of a thin tube storing ink containing a photothermal conversion substance and passing the laser light, whereby the ink is evaporated or thermally expanded. The ink is scattered, transferred to an image-receiving body or a printing plate-supporting body with the utilization of an ink pressure subsequent to the evaporation or thermal expansion of the ink. An ink image is accordingly formed. More preferably, a plurality of thin tubes are arranged, and the laser light of beam spots are scanned and exposed to side faces of the thin tubes, thereby scattering the ink in each thin tube. The ink image is easily transferred at high speed onto the image-receiving body or printing plate-supporting body. The photothermal conversion substance is one that generates heat when the laser light is shed, specifically, carbon black, graphite, etc.

IPC: H04W48/16
Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To allow a user of a mobile station to acquire base station busy information by distributing traffic and preventing congestion of a control channel in mobile communication. SOLUTION: A base station BS 1 monitors the number of busy communication channels. When the number exceeds a 1st threshold value, the base station BS 1 allows a busy mobile station belonging to the base station BS 1 and located in an overlapped radio area with an adjacent base station BS 2 with low traffic to hand over to the other base station BS 2. Furthermore, the base station BS 1 brings a standby mobile station belonging to the base station BS 1 and located in an overlapped radio area with the adjacent base station BS 2 with low traffic to the adjacent base station BS 2 so as to distribute the traffic. When there is no available communication channel, the base station BS 1 informs the standby mobile station about the information and the mobile station receiving the notice enters a dialing disable standby state.  Thus, congestion of control channels of the base station BS 1 due to useless redialing is prevented.

Title: Crystal plane orientation method
Inventor: IKUTSU HIDEO
IPC: H01L21/306
Filed: 1993-12-28
Abstract: PURPOSE:To obtain a good quantum fine line pattern by making it possible perform highly accurate plane orientation by forming in advance a pattern for verifying plane azimuth and then matching the angle in reference to this pattern. CONSTITUTION:An orientation vertification pattern Pn is formed by slightly deviating the angle by using a radial pattern P as a verification pattern which is widened in a radial shape from one point. If a substrate is etched using this orientation verification pattern Pn as a mask, then a required orientation can be verified by verifying its etching conditions. The radial pattern P becomes more effective by positioning it at both the sides of the substrate such as upper and lower sides or right and left sides. In this case, the center of radiation is positioned symmetrically but can be positioned at a corner. A train of patterns deviated with an arbitrary angle is satisfactory. As stated above, a pattern capable of verifying the orientation in advance is formed, and a fine line pattern is formed by referring to this pattern and then a good quantum device can be formed.
