Abstract: PURPOSE:To execute tracking with a high precision by obtaining a mirror surface adjusting turning angle suitable for a tracking error quantity at high speed in a magneto-optical disk device where a laser beam reflects on a mirror surface and the reflected beam is made incident on an optical disk recording medium and recording and reproducing data. CONSTITUTION:Information from any area between the areas divided in the direction of the radius of a magneto-optical disk 13 is discriminated by a zone discriminating circuit 1 based on address information Ad from an optical head 14. The mirror surface adjusting turning angle is calculated based on a coefficient set at every area from an area judging signal J and a tracking error signal Te from the optical head 14 by a gain switching circuit 2. The turning angle of the mirror surface is adjusted by a galvano-motor 18 in accordance with the calculated turning angle.

Abstract: PURPOSE:To attain thin profile and small size for a recording and reproducing device by welding a hub to a center hole surrounding of the main body by the ultrasonic wave welding so that a ring magnetic body is clipped with the main body. CONSTITUTION:A center of a through hole 20 of a hub 14 formed by fitting a ring magnetic body 13 to a fitting part 17 is made coincident with the center of a center hole 15 of an information disk main body 12 and an ultrasonic wave welding part 19 at the tip of the fitting part 17 is abutted against the surrounding of the center hole 15 and arranged. An ultrasonic wave is applied to the ultrasonic wave welding part 19 to melt the part 19 and welded to the information disk main body 12 to fix the hub 14. With the hub 14 welded in this way, the ring magnetic body 13 fitted to the fitting part 17 is not fixed to the information disk main body 12 but clipped between a flange 18 of the hub 14 and the information disk main body 12 to form an information disk 11. Thus, the recording and reproducing device is made thin in its profile and small in its size.

Abstract: PURPOSE:To attain low cost and miniaturization and to improve the reliability by giving a half turn to a permanent magnet in a desired direction with a torque exerted to the permanent magnet generated from a repulsing force caused by an external magnetic field formed by the permanent magnet and by a magnetic field by flowing a current to a coil. CONSTITUTION:The coil 25 is arranged around the permanent magnet 5 provided freely turnably and a torque in a desired direction is given to the permanent magnet 5 by a repulsive force between the magnetic field of the permanent magnet 5 and the magnet generated by flowing a current to the coil 25. In order to give the torque in the desired direction to the permanent magnet 5, for example, the turning center Lm of the permanent magnet 5 is shifted by a prescribed interval DELTAL in parallel with the coil center Lc along the length-wise direction of the permanent magnet 5. Since the repulsive force between the magnetic field caused by flowing a current to the coil 25 and the magnetic field by the permanent magnet 5 itself differs from the right and left side of the turning center Lm of the permanent magnet 5, the permanent magnet 5 is turned in the desired direction through the difference in the repulsive forces.

Abstract: PROBLEM TO BE SOLVED: To calculate the offset quantity included in an acceleration detection value by a simple clear method, and to thereby perform accurate correction of the acceleration detection value.
SOLUTION: First of all, the first acceleration detection value is acquired by a first-time data acquisition work. Then, a bicycle 70 is reversed by 180 degrees, and the second acceleration detection value is acquired by a second-time data acquisition work. The offset value is calculated from the mean value of the first-time and second-time acceleration detection values and stored in an EEPROM 20. Then, for example, an acceleration A/D value is acquired from an acceleration sensor 10 by periodical operations after start of the bicycle, and the offset value stored in the EEPROM 30 is subtracted from the acquired acceleration A/D value, to thereby calculate an acceleration value after correction. The tilt angle of the bicycle is calculated by using the acceleration value and used for calculation of the tilt angle of a slope where the bicycle is running, or the like. The method can be also applied to a biped walking robot or the like as well as the bicycle.

Abstract: PROBLEM TO BE SOLVED: To realize sophisticated function at a low cost as a whole, with no use of a premium microprocessor. SOLUTION: Each of a display part unit 40, a motor unit 50, and a vehicle controller unit 30 is provided with a microcomputer and a nonvolatile memory (EEPROM). Intrinsic information (parameter) is stored in each nonvolatile memory of the unit 30, 40, and 50. The microcomputer of a host unit (for example, a display part unit) reads the intrinsic information of each unit and selects and executes an optimum software, a part of which is born by the microcomputers of three units. The vehicle controller unit 30 and the motor unit 50 process arbitration each other, and selectively supplied with electric power of a battery unit 14. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To improve convenience by uniting functions of a position detection system and a bicycle.
SOLUTION: A display section unit 40 for displaying conditions of a traveling speed or a remaining amount of battery is provided with a GPS unit 44 detecting positional information by a GPS, and a navigation device including a map information memory 45 storing map information. Information on conditions such as a traveling mode or a traveling distance is displayed in half of the display screen of an LCD display section 41, and navigation information is displayed in the other half. Thus, the present position of the bicycle or a route to a destination as well as traveling conditions of the bicycle can be recognized easily, and necessary time or labor to the destination can be grasped easily. The display unit can be removed from the bicycle body to prevent a theft when the bicycle is not used.

SOLUTION: An assist torque calculating circuit has a low pass filter circuit 410, a calculation amplifier 420, a subtractor 430, and a limiter circuit 440. A detected signal of force-on-pedal detected by a torque sensor 35 is low-pass-filter-processed by a low pass filter circuit 410, The filter-processed signal is amplified by calculation amplifier 420 to calculate a total torque, difference between the total torque and the original detected signal is calculated by subtractor 430, and an assist torque command value is determined. By selectively controlling the cut off frequency in the low pass filter processing, riding feeling is selectively controlled by the simple constitution and control. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To enable a robot to stably continue a walking operation even if there is any obstacle on a road surface for the walking of the robot. SOLUTION: An acceleration sensor is fitted to a leg part 150 installed at the tip part of a movable leg, and the main control unit of a robot body detects the presence or absence of the interference of the leg part 150 with the obstacle 500 during the movement of the leg part 150 based on an output from the acceleration sensor. When it is determined that the interference is present, specified avoidance operations (backward and upward movements) are performed and then the movement of the leg part 150 is continued.
