Title: Method for monitoring damage of unused and new gas pipe
Inventor: IZEKI KOYA
IPC: G01M3/26
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To detect damage of a gas pipe in an early stage after the damage is caused by filling pressured gas in an unused and new gas pipe and a reference pipe placed in its vicinity and sealing them to detect a change with time in difference in gas pressures in both pipes. SOLUTION: Pressured gas, air or nitrogen gas for example is filled respectively in a new gas pipe 1 which has been buried prior to construction of a house and a reference pipe 2 placed at an appropriate place in its vicinity, the pipes are sealed, then a pressure sensor 3 is connected to the gas pipe 1 and the reference pipe 2 via connecting tubes 4a, 4b, and difference in pressures of the pressured gas in the pipes 1, 2 is detected. If both pipes 1, 2 are free from damage caused by subsequent construction or the like and have no leak, the difference in their pressure is not large, so that a monitoring means 5 may not generate a damage detection signal. However, if the gas pipe 1 has been damaged and a leak occurs, a pressure of the pressured gas in the gas pipe 1 gradually lowers to an atmospheric pressure, resulting in a gradual increase in the pressure difference.  Then the monitoring means 5 outputs a damage occurrence signal when the pressure difference exceeds a set value.

Title: Document editing device
Inventor: MATSUOKA SHIGERU
IPC: B41J35/36
Filed: 1990-08-24
Abstract: PURPOSE:To make reverse control of a cassette unnecessary by a method wherein the identification of an installed cassette ribbon is previously input, and when the ribbon end of the cassette ribbon is detected, if the cassette is a multi- time cassette, after stopping printing once, a head is turned off, rewinding is performed, and after detecting the leading end of the ribbon, reprinting is performed. CONSTITUTION:When ribbon end detection is detected at process 55 during printing, a carriage 25 is returned to the home position at process 56. Whether it is a one-time cassette or multi-time cassette is decided at process 57. As the result, in the case of one-time cassette, re-installation of a new one-time cassette is verified at process 58. Then, whether printing is continued or not is decided at process 59, and when printing is not continued, paper delivery motion is performed at process 54, and printing is completed. When printing is continued at the process 59, process 50 is performed. In this case, the carriage 25 moves from the home position to a printing position at which printing was interrupted, and printing is resumed.

Title: Image density control method
Inventor: IMAI TSUTOMU
IPC: G03G15/02
Filed: 1986-09-19
Abstract: PURPOSE:To raise the detection accuracy of a photosensor, and to control the image density with high accuracy by setting the electrostatic charge potential of the time of exposure of a reference pattern executed prior to exposure of an original image lower than that of the time of exposure of an original. CONSTITUTION:Prior to exposure of an original on an original platen 3, a reference pattern 4 which has been provided outside a placing area is exposed, and thereafter, the original is exposed and a latent image is formed on a photosensitive body 1, respectively. At the time of exposure of a pattern 4, a switch SW1 is set to a position J, and at the time of exposure of the original, by switching said switch to a position K, the electrostatic charge potential to an electrifier 18 is changed. The toner concentration being a pattern developed image is detected by a photosensor 10, and in accordance with it, a toner is replenished by a replenishing roller 14 of a developing part 9. Since the electrification potential for the pattern 4 has been set low, it become a detection pattern of a half tone, and since the detection accuracy of the sensor 10 is raised, the image density can be controlled with high accuracy.

Title: Fixing device
Inventor: SAKAI SHINICHI
IPC: G03G15/00
Filed: 1990-08-23
Abstract: PURPOSE:To prevent the soiling and winding of a sheet by reversely rotating a driving motor for a constant period set in advance just after jamming is detected. CONSTITUTION:The sheet on which toner is transferred from a photosensitive body is carried to the contact part of a heating roller 1 and a pressure roller 3. At this time, the driving motor 4 normally rotates the roller 1 like the allow C, the roller 3 is rotated like the arrow D, and the sheet is ejected in the direction of the arrow B. At this time, the sheet passes a paper end sensor, and time till the sheet reaches an ejecting sensor 7 after the sheet is fixed, is controlled by a controller 6. When the controller 6 detects the jamming, it interrupts all processes, and then, the motor 4 is reversely rotated only for the constant time set in advance. Thus, the sheet remaining on the rollers 1 and 3 is ejected in the opposite direction where the sheet is ejected. Thus, the causes of the soiling, the winding, etc., of the sheet can be prevented.
