Title: Image forming device
Inventor: TAKANASHI SATOSHI
IPC: G03G21/00
Filed: 2002-01-24
Abstract: <P>PROBLEM TO BE SOLVED: To always grasp the use temperature of a paper detection means, in an image forming device of a digital system which has a both-sided unit having a paper detecting means which triggers stopping of paper.  <P>SOLUTION: First and second paper carrying sensors 202 and 203 are provided to stop paper in stop positions (1) and (2). Paper is stopped in such a manner that after the leading end of the paper is detected by respective sensors 202 and 203, a stepping motor 110 is stopped after a fixed length of time and the paper is stopped. Axial current fans 201 are provided below carrying sensors 202 and 203. Temperature detection sensors 204 are provided near the sensors 202 and 203. The axial current fans 201 are turned on/off according to the detected temperatures. When the temperatures increase, the response accuracy of each of the temperature detection sensors 204 is degraded. In order to avoid it, stop control is exerted in advance. When the temperature is low, the response accuracy is adequate, the timing of stop is, therefore, delayed.  <P>COPYRIGHT: (C)2003,JPO

IPC: H01L27/148
Filed: 2002-01-30
Abstract: <P>PROBLEM TO BE SOLVED: To reduce a dark current in a semiconductor element and the white blemish appearing in picked-up images and, at the same time, to prevent the occurrence of smears caused by the light incident to a transfer area.  <P>SOLUTION: The gap between the upper surface of an Si substrate 18 and the lower surface of a light shielding film 30 is decided based only on the thickness of an SiO<SB>2</SB>film 28 and is made narrower. Consequently, the possibility that the light (shown by the dotted line) made incident from the opening 30a of the light shielding film 30 directly illuminates the transfer area is reduced. In addition, the incidence of the light to an insulating film underlying the light shielding film is reduced and the incidence of the light to the transfer area by irregular reflection is also reduced. Therefore, the occurrence of the smears can be prevented, because the conversion of the light made incident to the transfer area 18b into electric signals and the transfer of the converted electric signals are reduced.  <P>COPYRIGHT: (C)2003,JPO
