Patent number: 7359668Abstract: There is described a fixing device equipped in an image forming apparatus, which employs an electro-photographic method for forming an image on a transfer material, and having a lifetime longer than conventional one. The fixing device includes a first roller having a first elastic layer formed in a cylindrical shape on an outer surface of the first roller; and a second roller having a second elastic layer formed in a cylindrical shape on an outer surface of the second roller. A hardness of the second elastic layer is higher than that of the first elastic layer, and a nip section is formed between the first elastic layer and the second elastic layer. A longitudinal length of the first elastic layer in an axial direction of the first roller is greater than that of the second elastic layer in an axial direction of the second roller.Type: GrantFiled: June 21, 2005Date of Patent: April 15, 2008Assignee: Konica Minolta Business Technologies, Inc.Inventors: Hiroshi Funabiki, Yukio Okamoto

Patent number: 7324659Abstract: A frame is provided with an opening allowing insertion of a jig for setting an inner rim of a suspension holder to a proper position. The jig ensures positive alignment of the suspension holder when making connection to the frame. The jig also ensures reliable bonding of a diaphragm to the suspension holder with a bonding agent, since it steadily supports the suspension holder in position during the bonding process. The positioning of the bobbin and a voice coil is thus reliable when being assembled, thereby improving acoustic performance of a speaker.Type: GrantFiled: October 12, 2004Date of Patent: January 29, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Osamu Funahashi, Hiroyuki Morimoto, Yukio Okamoto
