Title: Image forming device
Inventor: KOZUKA NOBUHIKO
IPC: G03G21/00
Filed: 1988-11-30
Abstract: PURPOSE:To reduce damage to a photosensitive body owing to paper dust, etc., by supplying a proper place of the surface of the photosensitive body with toner irrespective of picture information, in an image forming device provided with an elastic blade which removes toner remaining on the photosensitive body after transfer. CONSTITUTION:Toner is supplied to the areas P1 and P2 on the surface of the photosensitive body of a rotating drum 8 based on picture information from a computer; however, toner is also supplied to areas T1 and T2 virtually irrespective of picture information. The lateral length W is the same as the longitudinal length of the elastic blade 26 which removes and recovers toner remaining on the drum 8 after transfer, or is slightly shorter and the length L in a moving direction is in a range of 1-5mm. Although toner images in the areas P1 and P2 are transferred to a sheet member such as a recording paper, the toner in the areas T1 and T2 acts as lubricant between the drum 8 and the blade 26, thereby preventing the surface of the photosensitive body from being damaged by paper dust, etc.

Title: Combustion apparatus
Inventor: KANAZAWA SHIGETOSHI
IPC: F23C13/00
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To enable continuation of catalytic combustion even in a condition where the flow rate of a fuel gas is lowered, by utilizing the heat storage function of a metal fiber which is in contact with a catalyst. SOLUTION: A metal fiber 16 is provided in the vicinity of a catalyst 15 and an igniter 17. Since the metal fiber 16 has a very small heat capacity as a nature of a fiber, it can be readily heated by an arc generated by the igniter 17. Therefore, a combustion gas 19 readily reaches an ignition temperature so as to achieve smooth ignition. Once catalytic combustion is started, the heat processed by an exhaust gas 18 heats the metal fiber 16. The metal fiber 16 can store this quantity of heat. For this reason, when the amount of supply of a fuel gas 11 to a combustion path 10 is reduced on account of temperature adjustment, for instance, the metal fiber 16 serves as an ignition source, thereby allowing stable catalytic combustion to continue.
