Abstract: <P>PROBLEM TO BE SOLVED: To securely prevent trouble to other trains on a track circuit including a turnout inward of an absolute signal in simple constitution without adding special construction between branched sections.  <P>SOLUTION: When the absolute signal 5 represents R, an 1T transmission part 8a transmits train control information including course information with track number information representing a course as A2 to a track circuit 1T. A 2T transmission part 8b transmits train control information including course information with track information representing a course as A1 to a track circuit 2T including the turnout 6. An on-vehicle device 12 receives train control information transmitted to the track circuit 2T when dielectric breakdown occurs at rail insulation 3 provided on the boundary between the track circuit 1T and the track circuit 2T as a train 1 is traveling on the track circuit 1T to detect noncoincidence of the track information of the track circuit 2T and the track circuit 1T, so that it cancels the train control information of the track circuit 2T to stop the train 1 by emergency brake control.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

IPC: H04N1/00
Filed: 2003-11-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image input apparatus that is operable even when it is disconnected from a computer.  <P>SOLUTION: The image input apparatus disclosed herein includes: an image read section; a recording section; a connection section; a connection discrimination section; and a control section. The image read section reads an image to generate image data. The recording section records and stores the image data. The connection section connects the image input apparatus to an external device. The connection discrimination section discriminates a connection state of the connection section. The control section carries out the system control of the image input apparatus. Through the configuration above, when the connection discrimination section decides that the external device is connected to the image input apparatus, the control section transfers the image data read by the image read section to the external device via the connection section. On the other hand, when the connection discrimination section decides that no external device is connected to the image input apparatus, the control section stores the read image data in the recording section.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To improve the cleanability of a spherical toner remaining after transfer by surely forming a weir at a low cost in a simple manner by using the spherical toner itself in a wedge-shaped part formed by a photoreceptor and a cleaning blade.  <P>SOLUTION: A DC voltage of a polarity different from the polarity of the post-development toner is applied to the conductive cleaning blade 13 and the post-development toner having nearly the uniformed electrostatic charging polarity is supplied to the edge-shaped part by the photoreceptor 1 and the cleaning blade 13 prior to image formation, as a result of which the rotating of the post-development toner is stopped by the electrostatic force of the cleaning blade 13 and the weir B is thereby formed. Consequently, the well cleaning of the post-transfer spherical toner at image formation is made possible. Since the spherical toner itself is used for this purpose, the occurrence of the deterioration in image quality is averted. In addition, there is no need for applying an AC voltage to the cleaning blade 13 and therefore the lower cost is necessitated and moreover, the inconvenience, such as the occurrence of the change in the properties of a photoreceptor surface 1a, can be averted.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
