Abstract: An electric telescopic steering apparatus includes a jacket having a lower jacket and an upper jacket in order to telescope the jacket; and a screw shaft arranged along a longitudinal direction of the jacket and held under a rotation-locked state. The screw shaft includes one end portion supported by one of the lower jacket and the upper jacket. The electric telescopic steering apparatus further includes a nut screwed on another end portion of the screw shaft and supported by another of the lower jacket and the upper jacket; a driving section configured to drive a rotation of the nut; and a displacement absorbing section provided between the one end portion of the screw shaft and the jacket.

Abstract: A female screw member 6 supported by a movable side bracket 31 includes: a movable side casing 61 provided with a nut container 67 through which a male screw shaft member 54 passes; and a pair of nuts 62 and 63 inserted into the nut container 67 non-rotatably but movably in an axial direction of the male screw shaft member 54 while threadedly engaging with the male screw shaft member 54. The movable side casing 61 includes a wedge member 64 whose tip end 64c is inserted between the nuts 62 and 63. The nuts 62 and 63 are separated from each other when the wedge number 64 is inserted therebetween, and outside surfaces 62c and 63c of female screw portions 62b and 63b of the nuts 62 and 63 come into contact with and get held by a male screw portion 54a of the male screw shaft member 54, thereby eliminating backlash between the female screw portions 62b and 63b and the male screw portion 54a.

Abstract: Provided is a steering column system capable of firmly holding a jacket during a normal condition and securing a larger movement stroke for the jacket when an excessive impact force is applied. To this end, when a clamp bolt (72) is fastened, sliding contact portions (70a) are pressed to abutment parts (43), respectively. Thus, a jacket (3) is firmly clamped to and held by a mount bracket (6). When a force in excess of a predetermined value is applied to the jacket (3) in its axial direction, shear portions (74b) break, and thereby a restraint imposed on a movement range by restraint portions (74a) is lifted. This contracts the jacket (3).

Abstract: A doctor blade for removing water, which excels in water removal capability and shape retention capacity, and suppresses abrasion of the belt or other mating member with which it cooperates, is a fibrous laminate comprising integrated base material and batt fiber layers. By impregnating resin into one side of the fibrous laminate, a layer in which the amount of impregnated resin is large and a layer in which the amount of impregnated resin is small are provided. In use, the layer in which the amount of resin is small is in contact with a belt or other mating member. The doctor blades can be adapted to the mating member easily, and excel in the water removal capability and shape retention, and suppress abrasion of the mating member.

Abstract: The power transmission comprises a pulley, a damper and a driver. The pulley has a hub, a web and a belt-wound portion. The hub is formed into the shape of a cylinder. The web extends outward from an outer surface of the hub. The belt-wound portion is formed into the shape of a cylinder and extends from an external circumferential edge of the web along the axial direction of the hub. The damper is disposed in the interior of an annular recess which is formed out of an outer surface of the hub, an end surface of the web and an inner surface of the belt-wound portion, and is fixed to the pulley. The driver is connected to the pulley at vertex portions thereof. The recess of the pulley is open towards the driver.

Abstract: A drive plate (E) for an automotive vehicle for transmitting a torque from a crankshaft (6) to a torque converter (7), while absorbing a thrust load applied from the torque converter to the crankshaft is formed with: a central mount portion (11) for mounting a crankshaft; an outer gear (20) formed in an outermost circumference of the drive plate; a plurality of weight reducing holes (30) formed between the central mount portion and the outer gear at regular angular intervals; and a plurality of the outer mount portions (12) for mounting a torque converter (7) formed near an outer circumference of the drive plate at regular angular intervals. In particular, the outer mount portions (12) are formed in such a way as to project radially inward from the outer gear (20) into the weight reducing holes (30), respectively.

Abstract: A paper making felt for use in hot press or press drying paper making processes comprising a base cloth layer and batt fiber layers, with at least the paper-contacting surface layer of the batt fiber layers composed principally of poly(paraphenylene benzoxazole) fiber. The felt exhibits a high degree of resistance to flattening, and consequently its effectiveness in removing water from the paper and its useful life for that purpose are enhanced.
