Patent number: 6670985Abstract: A PC card camera has a structure in which a universal joint to which a video camera is attached is mounted on a PC card body. The video camera comprises an optical lens unit and a solid-state area sensor of the photoelectric transducer type. The universal joint holds the video camera in such a manner that the angular position thereof can be adjusted freely with respect to the PC card. The PC card body is provided with a guide for guiding the card into a slot provided in a personal computer, a connector for connecting the PC card to the personal computer, and a cut-out which prevents the PC card from being inserted incorrectly. With the PC card connected to the personal computer, the angular position of the video camera can be adjusted via the universal joint.Type: GrantFiled: August 1, 1997Date of Patent: December 30, 2003Assignee: Canon Kabushiki KaishaInventors: Yukuo Karube, Masaharu Eguchi, Kentaro Matsumoto, Yoshihiro Shigemura, Kenichi Kotoku

Patent number: 4130769Abstract: A brushless motor has a rotor composed of a permanent field magnet, an armature functioning as stator and a position detecting element for detecting the positions of magnetic poles of said permanent magnet rotor and accordingly switching the electric current to an armature coil body of said stator thereby causing rotary motion of said permanent magnet rotor. Said armature coil body contains plural coils of given number of turns in a polygonal form of which at least two sides are placed parallel to the rotary axis of motor. Said coils are mutually arranged in a partially overlapping relationship to form a cylindrical body with one of said two sides being located at the internal surface of said cylindrical body while the other side is located at the external surface thereof so as to compose a coreless cylindrical armature body.Type: GrantFiled: October 31, 1975Date of Patent: December 19, 1978Assignees: Canon Kabushiki Kaisha, Canon Seiki Kabushiki KaishaInventor: Yukuo Karube

Patent number: 4015181Abstract: In a DC motor is provided with a revolving armature with an armature core having a plurality of salient poles and formed of soft magnetic material. Armature windings are coiled on the salient poles of the core, a commutator having a plurality of segments is electrically connected to the windings, and a centrifugal governor device is electrically connected in the current flow path to the windings. The governor switches of the governor device for controlling the speed of revolution of the revolving armature are provided between the salient poles of the armature core. A governor base for holding the governor switches has connecting terminal members for the governor switches and is disposed with respect to the armature windings on the same side that the commutator is disposed. Thereby, during assembly of the revolving armature, the procedures of connecting the governor switches to the current flow path of the windings are pronouncedly simplified as compared with the prior art motors.Type: GrantFiled: June 16, 1975Date of Patent: March 29, 1977Assignees: Canon Kabushiki Kaisha, Canon Seiki Kabushiki KaishaInventors: Yukuo Karube, Koji Suzuki, Ryoichi Ezaki
