Title: Exhaust emission catalyst purifier of cylinder injection system engine and exhaust emission purifying method
Inventor: MASUDA GOJI
IPC: B01D53/94
Filed: 2001-04-26
Abstract: PROBLEM TO BE SOLVED: To effectively purify a PM(particulate matter) with large particle diameter. SOLUTION: A wash coat layer 14b consisting of a porous substance having a pore with the diameter of 20 to 30 mm and cerium complex oxide (for example, ceria CeO2 ) is formed at the surface of a substrate 14a of a catalyst carrier inserted in an exhaust passage of a cylinder injection system engine, and noble metal (for example, platinum Pt) as an active component and rare earth metal (for example, cerium Ce) as an additive component are scattered and carried on the porous substance. This makes the PM with the large diameter, contained in the exhaust emission, be trapped in the pore of the porous substance, and suppressed to exhaust as not purified. The PM trapped in the porous substance is converted into the innoxious CO2 (carbon dioxide) with synergy of the active component and the additive component carried herein by oxidizing from the relatively low temperature.  In such a way, the trapping and oxidizing of the PM are repeated, and the continuous purifying of the PM is realized.

Title: Image forming apparatus
Inventor: IWAI SADAYUKI
IPC: G03G15/10
Filed: 2001-05-08
Abstract: PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of forming a satisfactory image causing little soiling of its background by preventing the sticking of toner from the non-image part of an image carrier. SOLUTION: In this apparatus, the electric potential difference between the surface electric potential of a photoreceptor 11 and the surface electric potential of an intermediate transfer belt 16c is set so that electric discharge is not generated at an image part but it is generated at the non-image part. At this time, when the electric discharge is generated once at the non-image part on the photoreceptor 11, the electric potential of the non-image part is attenuated and, moreover, the polarity of the toner left a little on the photoreceptor 11 is reversed by being affected by the electric discharge at development. As a result, the toner left on the non-image part of the body 11 is hardly transferred to the intermediate transfer belt 16c and the satisfactory image to which the sticking of the toner causing the soiling of the background is little is formed.
