IPC: H02P25/022
Filed: 2001-02-19
Abstract: PROBLEM TO BE SOLVED: To highly precisely recognize a pole position of a rotor of a synchronous motor by slightly turning the motor for avoiding the influence of disturbances such as a gravitational load, etc. SOLUTION: A first displacement information data V0C of a rotor pole, whose d-axis angle obtained by dividing into d-q axes is different from a reference phase θ0, determined by an exciting current applied to an armature coil of a synchronous motor, by an angle θ when a field phase command is the reference phase θ0, is detected (step 3). A displacement information data V180, when the field phase command is (θ+180 deg.), is detected (step 4). A displacement information data V-90, when the field phase command is (θ-90 deg.), is detected (step 5). A displacement information data V+90, when the field phase command is (θ+90 deg.), is detected (step 6).  The difference Δ1 between the displacement data V180 and the displacement data V0 and the difference Δ2 between the displacement data V+90 and the displacement data V-90 are obtained (steps 7 and 8). The angle θ is obtained from tan-1(Δ1/Δ2) (step 9). The pole position of the rotor is recognized as (θ0+θ) (step 13).

Title: Digital still camera
Inventor: SUENAGA KAZUNORI
IPC: G03B17/20
Filed: 2001-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a digital still camera(DSC) that facilitates precise focusing so as to improve the image quality of a photographed image. SOLUTION: The digital still camera can display an optional area of an image displayed on a liquid crystal display panel 42 and designated by a cursor 61 as a magnified image 62. A user utilizes a difference in gradation between adjacent pixels while viewing blocks in the unit of pixels displayed as the magnified image 62 to able to precisely match the focus of lens. Since the user has only to match the focus of lens while viewing the magnified image 62, the user can easily execute precise focusing. The magnified image 62 is displayed on a quadrant that is point-symmetrical to that of the cursor 61. Thus, even when the small-sized liquid crystal display panel 42 of the DSC 1 is in use, the cursor 61 and the magnified image 62 are not in duplicate displayed. Then the user can execute adjustment of an angle of an object and focusing at the same time.
