Title: Muffler for internal combustion engine
Inventor: KANESHI SADAHIKO
IPC: F01N1/08
Filed: 1985-06-20
Abstract: PURPOSE:To efficiently reduce production of exhaust noise and the surface temperature of a muffler, by a method wherein a space is formed between double casings of an inner and an outer casing, and the inner surface of the inner casing is formed in an uneven surface manner. CONSTITUTION:A muffler 1 is formed with an inner casing 2 and an outer casing 3 surrounding the whole surface of the inner casing 2 with a gap therebetween, and a space S, serving as a vacuum heat insulating sound insulating layer, is formed between the casings 2 and 3. An uneven surface 2g is formed on an inner surface 2f covering a drum part 2e and front and rear end walls 2a and 2b of the inner casing 2. With this constitution, exhaust gas flows through an introduction pipe 8 into a chamber A, and after the exhaust gas flows through communicating pipes 6 and 7 into the chambers B and C, it is exhausted through a tail pipe 9 to the open air. In which case, a sonic wave component collides with the uneven surface 2g for irregular reflection, and the component and the uneven surface are interfered with each other for damping. Further, the space S is vacuum, and this enables reduction of production of exhaust noise emitted from the muffler 1 itself and the surface temperature of the outer casing 3.

Abstract: PURPOSE: To enable secure and easy separation of transfer paper from the drum, by controlling the transfer device so that the electrostatic charge amount be smaller than at the time of transfer until the front end of transfer paper passes the transfer position of photosensitive drum by a specified distance.  
     CONSTITUTION: A transfer paper 11 is electrostatically charged in the reverse polarity of the toner image developed on a photosensitive drum 1 by a transfer device 5, and the toner image on the drum 1 is transferred on the transfer paper 11. This device 5 is also used as a charging device for separation 14, and the transfer paper 11 is charged so that the charge amount be smaller than at the time of transfer position of the drum 1 by a specified distance. Therefore, due to the toner image of the drum 1 charged in reverse polarity, the part of specified width from the end of transfer paper 11 is not electrostatically attracted to the drum 1, so that the transfer paper 11 may be easily and securely separated from the drum 1. The same effect will be obtained when the transfer device and charging device for separation are provided separately.
