Abstract: PROBLEM TO BE SOLVED: To provide a bolt tightening apparatus that structurally simply micro-vibrates a bolt at right angles to the bolt axis when tightening the bolt.
SOLUTION: A reducing eccentric cam 16 directly coupled to an input rotary shaft 14 fits peripheral external teeth with internal teeth on an inner circumference of a case 12A. The internal gear 12 synchronously rotates a coaxial, slow rotation rotor 20 via rotation transmission pins 22 to rotate a socket wrench 150, which tightens a bolt 110. A displacement controlling eccentric cam 24 is fixed at the rotation center of the reducing eccentric cam 16 so as to penetrate the rotation center of the slow rotation rotor 20. The displacement controlling eccentric cam 24 holds an axially penetrating displacement controlling pin 26 enclosed with double eccentric rings 24. The external teeth are fewer than the internal teeth. The rotation axes of the input rotary shaft 14 and displacement controlling pin 26 are offset, and the offset is adjusted by the rotational position of the double eccentric rings 24.

Abstract: PROBLEM TO BE SOLVED: To provide a plate-like member for core in which making current for obtaining the same driving power is reduced, and an involute core using it. SOLUTION: A plate-like member 10 for a core which is disposed in radial or convolute manner for a center axis line Y of a core, to form a core is constituted with an oriented silicon steel plate, and an readily magnetized direction thereof agrees with the center axis line direction Y, and the member is formed into a U-shape provided with an opening end part in the center axis line direction. The ratio of a width (b) in a direction vertical to the readily magnetized direction to a width (a) which is narrower of two leg parts 18 and 20 in a direction parallel to the readily magnetized direction of the plate-like member 10 for core, is 1.4 or more. Thereby a loss in the direction vertical to the readily magnetized direction is smaller than that in the readily magnetized direction, so that an electromagnetic force in the case of the same making current can be made large.

Abstract: PROBLEM TO BE SOLVED: To obtain a unidirectional or bidirectional rotational driving gear that delivers a large rotational angle, by securing one side of a driving body on an object other than mobile units, and joining a vibrator to the other end so that the width of the driving body will be almost the same as, or slightly smaller than, that of grooves. SOLUTION: Grooves 5 are formed on the rotary shaft 1 of a driving gear, and the grooves 5 are in contact with the side portions 6a, 6b of vibrators 2, 2'. The ends of the vibrators 2, 2' on one side are fixed at fixed portions 4 by means of fixtures. There are vibrators 2, 2' and vibrator elements 3, 3' on both sides of one fixed portion. For driving, oscillating force is applied to the vibrator element 3 (or 3') on one side of the fixed portion 4. If forward rotation is caused when the force is applied to the vibrator element 3, it follows that backward rotation is caused when the force is applied to the vibrator element 3'. In order to transmit oscillation of the oscillators 2, 2', they are joined to the vibrator elements 3, 3' at their surfaces. When the vibrators are expanded due to the oscillation of the elements 3, 3', frictional force is larger at the side portion 6a than at the side portion 6b. This is also the case when the vibrators are shrunken. This obtains a driving gear wherein the rotary shaft is rotated in the two directions and a large rotational angle is obtained.

Abstract: PURPOSE:To improve the control stability by constituting a suspension arm made of FRP so that the action of the tip accompanying the elastic deformation may be optimum thereby optimizing the alignment change accompanying the bound and rebound of a wheel. CONSTITUTION:This suspension arm has a plate-shaped arm body 32 made of FRP which is coupled, at one end, with the car body and is coupled, at the other end, with a wheel supporting member, and a friction member 34 which is arranged within the arm body, in the position being offset in the direction of board thickness to the neutral face of the arm body. The frictional member extends aslant, in the width direction of the arm body, along the neutral face 36, and abuts on the arm body with at least one face isolated in the direction of the offset from the neutral face, and the Poisson's ratio of the frictional member in the case where it is viewed in the board thickness direction to the longitudinal direction of the arm body is larger than the Poisson's ratio of the arm body.
