Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To prevent soiling of edge surface and obtain a transfer image without any soiling in an image forming device provided with a contact type transfer device. SOLUTION: In this image forming device utilizing a negative-positive developing process utilizing a photosensitive body with potential by electrification of -800 V, developing bias: B against a photosensitive body part in an non image range corresponding to the space between piece of paper and the range from the leading edge of transfer paper to 15 mm is set to be -450 V which is lowered than the developing bias A: -550 V against normal image range. Thus, the absolute value of developing surface potential is made greater in the range in the non image range and the transfer paper leading edge 15 mm (output timing (2)) than at normal times (output timing (1)). Therefore, the soiling of the edge part of the transfer paper is prevented by preventing the sticking of surface soiling toner in that part.

IPC: H04L12/437
Filed: 1990-11-29
Abstract: PURPOSE:To resume the communication of a terminal by detecting the fault of a branch line in a line concentrator, detaching the branch line having the fault from a duplex system ring-like transmission line and cutting off the branch line to the duplex system ring-like transmission line again after prescribed time elapses to conduct a test. CONSTITUTION:The line concentrator 20 detects the fault of the branch line 22 and the branch line 22 having the fault is detached from the duplex system ring-like transmission line 23. Then, the branch line is cut off to the duplex system ring-like transmission line 23 again after prescribed time elapses add the test of the branch line 22 is conducted. When the fault of the branch line 22 which is once detached is restored by the test, the test is judged to be normal and the branch line 22 is in a cut off state to the duplex system ring-like transmission line 23. When the fault is not restored, the test is judged to be abnormal. The branch line is detached from the duplex system ring-like transmission line again and it does not affect another network communication. Thus, the communication of the terminal can be resumed.

Title: Balanced piezoelectric filter
Inventor: TSUCHIKANE MASAE
IPC: H03H9/56
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To avoid frequency deviation after adjustment and attain miniaturization by forming a continuous conductive film with both gaps included while applying voltage to a set of exciting electrodes on one principal plane of a piezoelectric piece, dividing the conductive film with the Joule heat of an applied voltage and performing frequency adjustment. SOLUTION: A metal film 5 is formed on exciting electrodes 2b and 3b on one principal plane side of a crystal piece 1 with both gaps included by vacuum evaporation, etc., from the direction of an arrow P. In such a case, vacuum evaporation is continued while a direct current voltage E is applied to the electrodes 2b and 3b. Thus, on the metal film 5, connection by the vacuum evaporation and fusing by Joule heat are continuously repeated. And when the vacuum evaporation is stopped when a resonance frequency measured between terminals B and C reaches a specified value, the metal film 5 becomes a fusing state at voltage E.  Then, because frequency adjustment with a balanced type maintained can be performed without connecting the electrodes 2b and 3b in a common manner, the metal film 5 does not have be divided after the frequency adjustment and frequency deviation prevention after the adjustment becomes possible.

Filed: 1991-12-11
Abstract: PURPOSE:To prevent the leakage of ink from an ink tank and to fill the ink tank with ink to the full by constituting at least a part of a material constituting an ink tank of a gas permeable and liquid impermeable material. CONSTITUTION:For example, an ink tank 1 is formed from a porous resin material composed of fluoroplastic or polyethylene and limiting the passage of a liquid by its water repellency, pore size and void. In this case, it is desirable that the pore size is 100mum or less and the void is 95% or less in order to limit the passage of ink.
