    Abstract: PROBLEM TO BE SOLVED: To efficiently control the auxiliary power without using a mechanical torque sensor and to reduce the weight of the moving device. SOLUTION: A moving device 1 with an auxiliary power source 2 is provided with a speed detection means 3 and an acceleration detection means 4 for detecting the speed and acceleration thereof, and a incline detection means 5 for detecting a inclination of the moving device 1 or the driving road. A control means 6 controls the auxiliary power source 2 by calculating the auxiliary power value based on the detected information by the detection means. The control means 6 calculates a necessary work rate for maintaining the current speed of the moving device 1 and a necessary work rate for accelerating the moving device 1, and then obtains the auxiliary power value by multiplying the sum of both work rates by a coefficient value which is less than 1. Further the control means 6 obtains an operating point as an intersecting point of graph lines based on the auxiliary power value-speed power value-speed characteristic drawing and the work rate-operation speed characteristic drawing of the auxiliary power source 2. Therefore the control means controls driving of the auxiliary power source 2.

    Abstract: PROBLEM TO BE SOLVED: To efficiently form a spiral groove by arranging an action means to move a cutter in synchronism with rotation of a work by a rotary means and an action means to perform a notching action and a separating action of the cutter to the work in synchronism with rotation of the work by the rotary means. SOLUTION: A rotary means 110 rotates a sleeve 62, and a motor Ml and an actuator motor M2 of a tool post 141 having a driving mechanism act by a command of a control part 120. Therefore, a cutter 130 moves in the X1 direction and also advances in the Y1 direction in synchronism with rotation of the sleeve 62. Therefore, a spiral groove 270 is formed on an inner peripheral surface 64 of the sleeve 62 in the T1 direction. When its cutting action advances further, the spiral groove 270 is formed further in the T1 direction, and the cutter 130 once separates from the inner peripheral surface 64 by moving in the inverse direction.

    Abstract: PURPOSE:To obtain a stepping motor in which only a detent torque can be reduced by forming a nonmagnetized region on the magnetized surface of a rotor magnet opposed to the connecting part of stator cores for forming first and second phases. CONSTITUTION:A stepping motor 20 has a nonmagnetized region NB at a position opposed to a connecting part of a first phase coil 6 and a second phase coil 10 of a peripheral side face of a rotor magnet 16. A magnetizing yoke 30 is formed of a yoke 31 and a positioning member 32 in the case of inserting the magnet 16 into an insertion hole 34. Grooves 35 for winding a magnetizing winding are formed on an inner periphery 34, and through holes 36 passed from an outer periphery toward the groove 35 of the periphery 34 are formed in number corresponding to the grooves 35 along a circumferential direction. As a result, since a magnetic flux density for the connecting part can be made rough, a magnetic flux is scarcely converged to the connecting part thereby to effectively reduce detent torque generated by converging the magnetic flux to the connecting part.

    Abstract: PURPOSE:To reduce only a detent torque by inserting an inserted member consisting of a magnetic body where a plurality of parts protruding in a direction from a position opposing the peripheral side surface of a rotor toward the peripheral side surface are formed in periphery direction between first-phase and second-phase stator cores. CONSTITUTION:In an inserted member 22, a protruding part 22A which is as wide as magnetic pole teeth 5BT and 9AT is formed at the inner-periphery part of a ring-shaped member by the amount which is half the number of magnetic pole teeth 5AT/5BT or 9AT/9BT of a coil part 6 or 10 of each phase. Then, the center is shifted from the center of the magnetic pole tooth 5BT of the first phase coil part 6 by an electrical angle pi. Also, the magnetic pole tooth 9AT is shifted by an electrical angle of pi/2 for the magnetic pole tooth 5BT. thus causing the center of the protruding part 22A to deviate from the magnetic pole tooth 9AT by an electrical angle of pi/2 and hence reducing the cycle of a detent torque TD2 and dissipating and reducing generation of the detent torque.
