Inventor: SUZUKI YUJI
IPC: G03G15/09
Filed: 2002-01-31
Abstract: <P>PROBLEM TO BE SOLVED: To restrain the adhesion of a carrier to a latent image carrier and to obtain a high image density while improving the reproducibility of a thin line and restraining a rear end void phenomenon in an image forming apparatus (a high-speed machine) whose image forming speed is high.  <P>SOLUTION: A magnetic brush is formed by napping developer on a developing sleeve 4 by a main magnetic pole being an N pole and two auxiliary magnetic poles being S poles arranged to be opposed to a developing area where the sleeve 4 and a photoreceptor drum 1 are mutually opposed in the developing area, and it rubs to develop an electrostatic latent image on the drum 1. In the developing device, the length of the magnetic brush is short and the density of the edge part of the magnetic brush coming into contact with the latent image carrier is made high, so that the rear end void phenomenon is restrained but the linear velocity of the sleeve 4 must be made high with reference to that of the drum 1 in order to maintain the high image density. Therefore, the carrier easily adheres to the drum 1, but the adhesion of the carrier is restrained by using the carrier whose saturation magnetization value is within a specified range.  <P>COPYRIGHT: (C)2003,JPO

Title: Pneumatic radial tire and its manufacturing method
Inventor: NEMOTO MASAHIRO
IPC: B29D30/30
Filed: 2002-03-07
Abstract: <P>PROBLEM TO BE SOLVED: To efficiently manufacture a pneumatic tire formed that air residual proportion defective and noise performance are compatible with each other.  <P>SOLUTION: A belt-form reinforcing rubber strip 30 is formed that parts of only 1/2L<SB>2</SB>width are situated on both sides of a cord bundle 28 consisting of a reinforcing cord. A belt reinforcing layer 22 is formed in a way that a reinforcing rubber strip 30 is wound spirally on a belt 21 without any gap as side edge parts are adhered to each other. Thus, the surface of the belt reinforcing layer 22 is formed in a flat state and a tread can be stuck without leaving air between the belt reinforcing layer 22 and the tread and a high quality pneumatic radial tire freed from unnecessary air in the tread can be provided. Since a plurality of parts where arrangement density in the direction of the width of the tire of the reinforcing cords 26 is low are formed at intervals in the direction of the width at the belt reinforcing layer 22, the belt reinforcing layer is more difficult to vibrate than a conventional belt reinforcing layer where arrangement density is uniformly set in the direction of the width of the tire, and the occurrence of cavity resonance can be suppressed.  <P>COPYRIGHT: (C)2003,JPO
