Patent number: 8655025Abstract: Provided is a data analysis device for automatically detecting a step on the ground based on point cloud data representing a three-dimensional shape of a feature surface. A space subject to analysis is divided into a plurality of subspaces. A boundary search unit (22) searches for a boundary formed by the step on a horizontal plane for each of the subspaces. The boundary search unit (22) searches for a step neighborhood area having a predetermined width, in which the points projected on the horizontal plane are accumulated equal to or more than a criterion set in advance and a cloud of the points have a difference in height equal to or more than a step threshold set in advance, and searches for a directional line along a distribution of the cloud of points belonging to the step neighborhood area on the horizontal plane as the boundary.Type: GrantFiled: January 26, 2012Date of Patent: February 18, 2014Assignee: Pasco CorporationInventors: Shizuo Manabe, Ikuo Kitagawa

Publication number: 20080097325Abstract: Disclosed are a method and apparatus for controlling the injection rate of an anesthetic solution in a cartridge type motor-driven injection syringe for dental use, particularly beginning with the “Low” rate injection at the outset, and switching to the “Medium” or “High” injection rate at an arbitrarily selected time in the course of injection. The speed of revolution of the electric motor is changed among the low, medium and high speed, and a two-step operable type of switch is used as a starter switch 13. The first depression of the starter switch makes the electric motor 9 start at the low speed, thereby making the plunger rubber 5 initially move at the “Low Speed” in the cartridge 6 via the plunger rod 12, and the second depression of the switch makes the electric motor 9 run at the low, medium or high speed, and accordingly the plunger rod moves at the selected “Low Speed”, “Medium Speed” or “High Speed”.Type: ApplicationFiled: August 24, 2007Publication date: April 24, 2008Applicant: Showa Yakuhin Kako Co., Ltd.Inventors: Fumio Tanaka, Yoshihiko Kawasaki, Mitsuhiro Haraguchi, Ikuo Kitagawa, Yoshinori Kato, Renji Hayashi

Publication number: 20050236289Abstract: There is provided an injection needle removing apparatus for dental cartridge syringe comprising a chuck device (22) mounted within a housing (11) and including chuck jaws (26) for gripping a needle hub (25?), means for opening and closing the chuck jaws, a needle receptacle (14) adapted to rotatably support the housing (11), and means (50, 55, 56) for rotating the housing relative to the receptacle, the rotation of the housing causing the chuck device, together with the housing, to be rotated relative to the injection needle, thereby removing the injection needle from the syringe. In this arrangement, any rotative power transmission mechanism is not required to rotate the chuck device itself relative to the syringe.Type: ApplicationFiled: June 17, 2005Publication date: October 27, 2005Applicants: SHOWA YAKUHIN KAKO CO., LTD., HIOS INC.Inventors: Fumio Tanaka, Kazuhiro Ono, Ikuo Kitagawa, Renji Hayashi, Yoshinori Kato, Kiyoshi Wakabayashi

Patent number: 6582405Abstract: An electrically-driven dental injector used in orally injecting such an injection liquid as an anesthetic in dental treatment. Electrically-driven dental injectors includes one having a mechanism for disengaging a pinion (82) from a rack (48) in order to retract a plunger rod (44) upon completion of injection; however, it has heretofore been necessary to manually operate the operating part from outside each time. The inventive electrically-driven dental injector is so arranged that the plunger rod can be manually pushed back directly oupon completion of injection without requiring manual operation, and, to this end, the injector comprises a latch mechanism (84) for engaging/disengaging the ring gear (70) of a planetary reduction gear (50) with/from a casing (52), and an operating rod (94) extending through a support member (20) and functionally cooperating with the latch mechanism (84).Type: GrantFiled: May 7, 2001Date of Patent: June 24, 2003Assignees: Showa Yakuhin Kako Co., Ltd., Hios Inc.Inventors: Yukio Kawagishi, Fumio Tanaka, Mutsumi Shibuya, Ikuo Kitagawa, Renji Hayashi, Yoshinori Katoh

Patent number: 4208555Abstract: The present invention is directed to a torque control device for an electrically driven tool. The torque control device includes a stationary cam rotatably and detachably connected to an output shaft and a movable cam adapted to be rotatably and slidably engaged by said stationary cam. An adjustable screw cover is provided for adjusting the compression force of a spring against the movable cam thereby regulating the torque acting on the driven tool. The slidably connection between the stationary cam and the movable cam enables the releasing of the rotational force supplied to the stationary cam when the load on the driven tool exceeds a predetermined set torque.Type: GrantFiled: June 10, 1977Date of Patent: June 17, 1980Assignee: Olympic Fishing Tackles Co., Ltd.Inventors: Katsuzo Ikeda, Ikuo Kitagawa
