Patent number: 9630444Abstract: When the rear axial cylinder (3) is rotated, the cam cylinder (17) is also rotated, thereby the cam protrusion (18a) moves forward by means of the functions of the cam groove (17a) and the slit (18b), so that the slider (18) moves forward to cause the writing body (14) to move forward against a biasing force by the biasing member (15). The cam cylinder (17) and the rear axial cylinder (3) are fixed via the adjustment mechanism of rotational positions (17n).Type: GrantFiled: September 20, 2013Date of Patent: April 25, 2017Assignee: Kabushiki Kaish Pilot CorporationInventor: Masaaki Kubota

Patent number: 9493028Abstract: A rotating-operation type of writing tool is provided in which a front axial cylinder and a rear axial cylinder are separable and a tip portion of the writing tool is caused to protrude from a front portion of the front axial cylinder by a rotating operation of the rear axial cylinder. When the rear axial cylinder (3) is rotated, the cam cylinder (17) is also rotated, thereby the cam protrusion (18a) moves forward due to the functions of the cam groove (17a) and the slit (18b), so that the slider (18) moves forward to cause the writing body (14) to move forward against a biasing force by the biasing member (15). The slider (18) has the hollow body (18m), the coil spring (18c) and the flange body (18f). The O-ring (19) is provided on the outer circumference of the flange body (18f).Type: GrantFiled: September 20, 2013Date of Patent: November 15, 2016Assignee: KABUSHIKI KAISHA PILOT CORPORATIONInventors: Masaaki Kubota, Takashi Iwahara

Patent number: 5731982Abstract: Finishing allowances are given to a structure by a CAD/CAM system, and cutter path data for machining the finishing allowances are simultaneously generated. A surface finish is indicated on a die structure by a finishing mark. Finishing allowances are given to the die structure, producing a die structure with finishing allowances. Thereafter, a physical interference is confirmed on a screen image in order to generate cutter path data for a cutter head with respect to the die structure. If an interference occurs, the operator replaces a cutter with a longer cutter, and confirms again a physical interference. Cutter path data with respect to the die structure with finishing allowances can be generated substantially automatically.Type: GrantFiled: April 11, 1996Date of Patent: March 24, 1998Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takaoki Namba, Masaaki Kubota, Soichi Yamamoto

Patent number: 4941793Abstract: In a system for removing press-formed parts formed in a pressing machine, a loading transfer device is disposed between an ejection position to which a plurality of press-formed parts are simultaneously ejected in parallel from the pressing machine and a loading position established to load the press-formed parts onto each of a plurality of carrier pallets which are on standby in parallel to individually correspond to the plurality of press-formed parts. The loading transfer device comprises a plurality of transfer pallets connected to one another with variable spacings therebetween and reciprocally movable in parallel between the ejection position and the loading position so that the plurality of press-formed parts may be placed onto the individual transfer pallets, and a spacing-varying drive device for varying the spacing between the transfer pallets. During transferring of the press-formed parts by the loading transfer device, the spacing between the press-formed parts is varied.Type: GrantFiled: December 20, 1988Date of Patent: July 17, 1990Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Motoatsu Shiraishi, Masaru Sasagawa, Ken Tazo, Masaaki Kubota, Shinji Katayama
