Publication number: 20060023283Abstract: A first f? lens is arranged to form an inclination angle ?1 to a main scanning plane. A second f? lens is arranged to form an inclination angle ?2. In order to determine the inclination angles ?1 and ?2, curvature amounts of scanning lines generated on a scanned surface are measured when the f? lenses are independently inclined one at a time at a minute angle. Change rates K1 and K2 are obtained from the measured curvature amounts and the minute angles. The inclination angles ?1 and ?2 are determined such that |K1 ?1+K2 ?2| is no more than a certain value.Type: ApplicationFiled: July 28, 2005Publication date: February 2, 2006Applicant: Fuji Photo Film Co., Ltd.Inventors: Yoshinori Morimoto, Tadashi Masuda, Tsuyoshi Tanabe, Kiyoshi Kondo, Kenichi Saito, Yoichi Suzuki

Patent number: 5480508Abstract: A prepreg tape is firstly prepared by bonding prepreg layer to a backing paper and then the prepreg tape is cut to a depth enough to cut the prepreg tape but not the backing paper. A unnecessary portion of the prepreg tape is removed from the backing paper to obtain a cut prepreg tape. A laminating attachment is moved in a predetermined direction while urging the prepreg tape against the surface of an operating table. The cut prepreg tape is peeled off from the backing paper and the peeled off prepreg tape is bonded to the operating table. The cut prepreg tapes are successively oriented in a predetermined direction and juxtaposed to form a laminated sheet. When the sheet is mounted on a mold of a predetermined shape. When the impregnated thermosetting resin is perfectly cured under heat and pressure a product useful for assembling various vehicles can be obtained.Type: GrantFiled: August 18, 1994Date of Patent: January 2, 1996Assignees: Toshiba Kikai Kabushiki Kaisha, Fuji Jukogyo Kabushiki KaishaInventors: Takao Manabe, Yuhei Yamakawa, Shoichi Shin, Hideyuki Yamada, Mitsuo Nagashima, Mitsunori Kokubo, Masafumi Tsunada, Yasuhiko Nagakura, Yukio Nakajima, Tomohiro Inoue, Kiyoshi Kondo
