IPC: G03G15/16
Filed: 2007-06-12
Abstract: <P>PROBLEM TO BE SOLVED: To automatically detect the presence or absence of fog with ease without wastefully consuming a recording medium such as paper.  <P>SOLUTION: While fog toner images are absent on an intermediate transfer belt 18, the density of the surface of the belt 18 is detected by a density sensor 20. Fog toner images are formed on a photoreceptor 11 and the transfer of these images to the intermediate transfer belt 18 is carried out over more than one time, thereby superimposing the fog toner images onto the intermediate transfer belt 18. The density of the fog toner images formed by the superimposition is detected by the density sensor 20. The density of the detected fog toner images and the density of the surface of the intermediate transfer belt 18 when fog toner images are absent are compared with each other. If a difference between them is equal to a specified value or greater, the fog is determined to be present.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Filed: 2007-07-25
Abstract: <P>PROBLEM TO BE SOLVED: To inhibit generation of the internal pressure by solidification of a working fluid and to improve durability of a heat exchanger in a heat pipe type heat exchanger provided with inner fins.  <P>SOLUTION: The lower end 8c of an inner fin 8 arranged in a heat pipe 3a is positioned above the top surface position F of a working fluid at the time of a liquid state. At the time the working fluid of a liquid state in the heat pipe 3a starts to solidify, the top surface of the working fluid does not contact the inner fin 8 therefore the heat transfer becomes slow and solidification of the top surface of the working fluid in the heat pipe 3a becomes slow. Accordingly, the volume of the liquid state working fluid confined in the inside of the solid state working fluid is decreased at the time the top face of the working fluid in the heat pipe 3a is solidified and blockaded, thereby generation of the internal pressure by solidification of the liquid state working fluid is inhibited.  <P>COPYRIGHT: (C)2008,JPO&INPIT
