20080275665 | ABSOLUTE ANGLE DETECTING DEVICE - Disclosed is an absolute angle detecting device that requires an angle corresponding to one step of a cyclic gray code in order to perform initialization and to determine the errors of a detecting element. The disclosure provides an absolute angle detecting device for detecting the absolute angle of a rotating body. The absolute angle detecting device includes: a storage unit that stores an N-bit cyclic gray code, which is a combination of binary digits ‘1’ and ‘0’; N detecting elements that are arranged along a code pattern; and a data determining unit that compares an N-bit code string output from the N detecting elements with the N-bit cyclic gray code. In the cyclic gray code, when N is an even number, the number of is included in the code string in each step is N/2 or (N+2)/2. When N is an odd number, the number of is included in the code string in each step is any one of (N+1)/2, (N−1)/2, (N+1)/2, and (N+3)/2. | 11-06-2008 |

20100295541 | MULTI-ROTATION ANGLE DETECTION DEVICE - A rotating axis of a first driven gear provided with a magnet and a rotating axis of a second driven gear provided with a magnet are orthogonalized with respect to a plane which includes a rotating axis of a rotor having a first gear and a second gear each with a different number of teeth concentrically provided for a flanged gear forming section. | 11-25-2010 |
20110219895 | LEVER OPERATION DEVICE - A rotating knob is rotatably attached to an outer peripheral portion of an operation lever. The rotating knob has a lead thread portion on the inner surface thereof, and the lead thread portion meshes with external teeth of a ring gear. Internal teeth of the ring gear mesh with speed-increasing gears, and permanent magnets are fixed to the speed-increasing gears. A circuit board is arranged in the operation lever so as to extend along the axial direction thereof, and magnetic sensors mounted on the circuit board are opposed to the permanent magnets at positions close thereto. Accordingly, the operation position of the rotating knob can be detected by the magnetic sensors. The gears, the circuit board, etc., are supported by a support case and a cover case to form a switch unit. | 09-15-2011 |
20110221551 | LEVER OPERATION DEVICE - A lever operation device includes a movable support member that supports a base portion of an operation lever such that the base portion is pivotable along a first operation plane, a housing that supports the movable support member such that the movable support member is pivotable along a second operation plane that is orthogonal to the first operation plane, an actuator holder attached to the base portion such that the actuator holder is rotatable along the second operation plane, a first actuator retained by the actuator holder, and a second actuator retained by the movable support member. The housing is provided with a first cam surface and a second cam surface on an inner wall surface thereof, the first actuator and the second actuator being in elastic contact with the first cam surface and the second cam surface, respectively. | 09-15-2011 |
20120056761 | ROTATION INPUT DEVICE - In a rotation input device, a planetary carrier, connected to an operation knob, rotatably supports a planetary gear which meshes with an outer teeth row provided for a sun gear, to which an output shaft is secured, and also meshes with an inner teeth row provided for an outer gear. A plunger provided for the sun gear is in elastic contact with a recess cam provided for the outer gear.
