Title: Image recorder
Inventor: SAIKAWA TAKESHI
IPC: G03G21/06
Filed: 1991-10-15
Abstract: PURPOSE:To obtain an image recorder which is free from the occurrence of the stain of a recording head and the occurrence of tailing of a highly-resolved electrostatic latent image and is miniaturized, highly reliable and has high image quality by providing a heating layer which can be energized selectively as a recording medium. CONSTITUTION:As the recording medium 1, a medium provided with the heating layer which can be selectively energized is employed. The recording medium 1 itself is heated by selectively energizing the heating layer of the recording medium 1 by means of the recording head 10, thereby destaticizing it with heat. After the surface of the recording medium 1 is uniformly electrified, the heating layer of the recording medium 1 is energized by the recording head 10 according to image information and the energized part of the heating layer is heated in the form of a spot by the resistance. When the surface of the recording medium 1 is heated higher than the prescribed temperature by the heating of the heating layer thereafter, charges on the surface of the recording medium 1 are dispersed, so that heat destaticization is caused to form an electrostatic latent image on the surface of the recording medium 1.

Title: Communication monitoring device and wide area network system
Inventor: KATSURAGAWA YASUYOSHI
IPC: H04L12/46
Filed: 1995-11-13
Abstract: PROBLEM TO BE SOLVED: To reduce useless communication costs by detecting the abnormal communication state of no data communication even during the connection of a line. SOLUTION: After the line is connected, a remote communication monitoring device monitors the presence/absence of communication data on the line. At the time of a non-communication state having no data, the monitoring device activates a non-communication time measuring means 202, measures non- communication time and inspects whether this measured time exceeds prescribed non-communication time or not. When the measured time exceeds the prescribed non-communication time and it is judged that the line connection time is within two seconds just before the border of connection unit time to be a communication tariff charging unit, for example, the line is disconnected by a disconnecting means 204. When there is a period longer than two seconds, the presence/absence of communication data is judged again. Thus, since the line is not immediately disconnected but disconnected just before the unit time when the non- communication time is continued longer than the prescribed time, the abnormal communication state can be efficiently detected.

IPC: H01L29/792
Filed: 1990-10-31
Abstract: PURPOSE:To have the control gate perform the selective gate functions and make the selective gate unnecessary by forming a channel directly controlled by the control gate in the 1st selective epitaxial layer that touches the 3rd gate insulation film. CONSTITUTION:A source region 8 is formed to a depth equivalent to the top portion of a control gate 5 and a drain region 9 is formed to a depth equivalent to the top portion of a floating gate 3 which is positioned lower than the surface of the control gate 5. As a result, a channel region 10 which is controlled by the control gate 5 is formed in the 1st selective epitaxial layer 7A on the source side below the source region 8. Since this channel region 10 which is directly controlled by the control gate 5 is formed directly below the source region 8 of the 1st selective epitaxial layer 7A and on the silicon surface next to the control gate 5, the portion of the control gate 5 touching this channel region 10 performs the same functions as a conventional selective gate and it is possible to prevent overerase without creating an independent selective gate.
