Patent number: 6470166Abstract: Disclosed here is a color-image forming apparatus that minimizes damage caused by friction between a photosensitive drum and an inter-stage transfer belt. The apparatus includes a plurality of image-forming units, each of which has the photosensitive drum carrying an electrostatic latent image thereon, a developing unit forming a toner image by applying toner to the latent image. Having different color toners therein, the image-forming units are organized into a tandem layout. The inter-stage transfer belt is looped over plural rollers to form an endless path. While traveling the path along the direction in which the image-forming units are arranged, the belt forms a full-color toner image thereon by transferring plural toner-images on the drums one upon another. The belt is controlled to come into contact with the drums only while accepting the toner image from the drums.Type: GrantFiled: May 9, 2001Date of Patent: October 22, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshihiro Mizoguchi, Tadashi Shimotoso, Takashi Yoshihara, Yuji Nagai, Kazuhiro Ogata

Patent number: 5808495Abstract: According to the present invention, to drive a magnetron, a pulse voltage is applied to the gate electrode of a field effect transistor to make the field effect transistor conductive, so that a voltage stored in a storage condenser is discharged through the primary winding of a pulse transformer and the drain electrode-the source electrode of the field effect transistor. This discharge causes the voltage generated at the primary winding of the pulse transformer to be induced at the secondary winding of the pulse transformer. Thus, the magnetron connected to the secondary winding of the pulse transformer is driven.Type: GrantFiled: December 23, 1994Date of Patent: September 15, 1998Assignee: Furuno Electric Company, LimitedInventors: Hidetoshi Tanigaki, Takashi Yoshihara, Yoshihiro Ishii
