Patent number: 7258209Abstract: A brake drum includes a ring-shaped drum body, and a friction member secured to the inner circumferential surface of the drum body. Because the drum body is formed of a lightweight Al alloy and the friction member is formed of an Al-base composite material, the brake drum can be reduced in weight as a whole. Further, because the friction member, having projection portions formed on its outer periphery, is cast enveloped by molten metal of the Al alloy, the friction member and the drum body can be firmly fastened together. Thus, even when a great braking force is applied to the drum brake, the friction member can be prevented from being undesirably detached from the drum body.Type: GrantFiled: November 23, 2004Date of Patent: August 21, 2007Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takashi Koizumi, Takaharu Echigo, Hiroto Shoji, Yasuhiro Nakao, Kunitoshi Sugaya

Patent number: 6966966Abstract: A protective sheet peeling device which reliably separates, from a sheet, a protective sheet (an interleaf sheet) which is superposed with one surface of the sheet. A free roller is disposed at a downstream side of a conveying roller of a peeling section, in a state in which one portion of the free roller is disposed on an “imaginary conveying locus” of a printing plate precursor. Further, a displacement roller is disposed at a downstream side of the free roller. After the printing plate precursor, which is superposed with the interleaf sheet, has passed by the free roller, when the displacement roller moves to a position of reaching the “imaginary conveying locus”, the printing plate precursor and the interleaf sheet are curved along the free roller. Due to reverse rotation of the displacement roller, the interleaf sheet is peeled off of the printing plate precursor.Type: GrantFiled: December 8, 2003Date of Patent: November 22, 2005Assignee: Fuji Photo Film Co., Ltd.Inventors: Takashi Koizumi, Yoshinori Kawamura

Patent number: 6935238Abstract: A conveying device for a printing plate precursor which takes the printing plate precursor and an interleaf sheet out from a cassette, and which, along a conveying path to an exposure section, takes-off only the interleaf sheet. When a leading end of the interleaf sheet passes by an interleaf sheet peeling roller disposed on the conveying path, the interleaf sheet peeling roller rotates in a direction opposite to a direction of conveying to the exposure section, and contacts the interleaf sheet, and slack is formed in the interleaf sheet between the interleaf sheet peeling roller and a conveying roller. A slack portion is nipped between two belts and fed to a forked-off path, and the interleaf sheet is removed from the conveying path. It is possible to feed only the printing plate precursor out to the exposure section while continuing to convey the printing plate precursor.Type: GrantFiled: October 8, 2003Date of Patent: August 30, 2005Assignee: Fuji Photo Film Co., Ltd.Inventors: Yoshinori Kawamura, Takashi Koizumi, Kazuoki Komiyama, Yoshihiro Koyanagi

Patent number: 6929258Abstract: A sheet feeder for use, with a stack having plates and sheets alternating. Sheets are removed by being reliably suction adhered with a sucker. The sheet feeder includes a suction device, and the sucker and device are mounted at a supporting portion. In order to allow suction adhering of the plates and sheets alternately stacked in a magazine, the suction device is operated when the sucker is brought into contact with the sheet, and the sheet is raised separately from the plate. Thereafter, the sheet is suction adhered to the sucker by suction. This makes it possible to prevent the sucker from suction adhering to the plate together with the sheet, and only the sheet is reliably from the stack.Type: GrantFiled: December 4, 2003Date of Patent: August 16, 2005Assignee: Fuji Photo Film Co., Ltd.Inventors: Tsukasa Ono, Takashi Koizumi, Yoshinori Kawamura, Kazuhisa Okamoto
