Abstract: The outer diameter of a spline nut and the inner diameter of a nut body holding portion of a housing gradually decrease in the downward direction. A ball screw protection unit includes a nut body taper face that is formed in the outer peripheral face of the spline nut, a holding portion taper face that is formed in the nut body holding portion, and a disc spring that is provided at the upper end of the spline nut and that biases the spline nut in such a direction that a friction force between the nut body taper face and the holding portion taper face increases (downward direction).

Abstract: A ball screw unit includes a screw shaft that includes a screw groove, a ball screw nut that is screwed to the screw shaft via balls and that rotates to move the screw shaft linearly in an axial direction of the screw shaft, a hollow shaft that rotates together with the ball screw nut, a housing that rotatably supports the hollow shaft via a rolling bearing, and an elastic member that is provided at a position between the rolling bearing and the housing.

Abstract: A disc spring is provided between a ball screw nut and a hollow shaft, and another disc spring is provided between rolling bearings and a housing. When leftward motion of a screw shaft is stopped and a rotational inertia force is applied to the ball screw nut, these disc springs allow the ball screw nut to rotate to a certain degree.

Abstract: A suspension device S interposed between a sprung member B and an unsprung member W of a vehicle, comprising an actuator A, a hydraulic damper D, and a direction changing mechanism T for changing a linear motion of the actuator A into a linear motion in an opposite direction and transmitting the opposite linear motion to the hydraulic damper D. When a high-frequency vibration acts on the unsprung member, the drawback that the vibration is apt to be transmitted to the sprung member B under the influence of moment of inertia of the actuator A is remedied and it is possible to improve the ride comfort in the vehicle.

A pomegranate juice containing substantially no glucose and no fructose; a pomegranate juice containing not more than about 50% of the glucose and fructose of a pomegranate juice and having about 50% or more of the estrogen-like activity of the pomegranate juice; a pomegranate juice having an estrogen-like activity of about 96 U per gram of glucose and fructose contained in the juice; a pomegranate juice powder having an estrogen-like activity of about 40 U or more per gram of the powder; a pomegranate juice powder containing glucose and/or fructose and having an estrogen-like activity of about 80 U or more per gram of glucose and fructose contained therein; and like powders.

Abstract: A structure of a spectrum spreading communication device which solves the problem with the conventional spectrum spreading communication using Barker codes, etc., and limits the rise of the side-lobe of a correctional signal independently of the order of information codes by use of a code sequence having a code length of at least 14. The spectrum spreading communication device uses a pseudo-noise code having code length of at least 14 and a self-correlation side-lobe of not greater than 3 as a pseudo-noise code of a direct spreading communication device which uses the pseudo-noise codes whose polarities are inverted so as to deal with also digital information. Thus, even when the pseudo-noise code length is 14 or more, the side-lobe of the correction coefficient can be restricted. Accordingly, the error rate of the spectrum spreading communication device is reduced and the processing gain is improved.

Abstract: A rubber tire individual separation transport apparatus including a rubber tire individual conveyor surface section and a rubber tire sliding surface section separately formed on a slat conveyor surface, with the conveyor having a horizontal charge zone, a sharply inclined individual transport zone, and a horizontal discharge zone. Also included is an upright plate erected for contact with the peripheral surface of a rubber tire at one end of each slat in the individual conveyor surface section. A support plate of such a size as to support only one rubber tire laid flat on said individual conveyor surface is mounted at a larger pitch in the direction of transport than the maximum diameter of the rubber tire being conveyed. A stationary side wall is erected along the side edge of the other end of the slat of the sliding surface section. Cooperative action between the selected tire and the side wall causes frictional force on unwanted tires to cause them to fall back to the supply of tires.

Abstract: The sharply inclined transport surface of a slat conveyor is divided into an individual conveyance surface section and a sliding surface section; and a support plate in said individual conveyance surface section supporting only one rubber tire laid flat on said individual conveyance surface section is mounted at a larger pitch in the direction of transport than the maximum diameter of the rubber tire being conveyed. A mixed-suspended state collapsing member is mounted on a frame of said slat conveyor so as to project toward said rubber tire sliding surface section. Not only is a single rubber tire separated and carried out by a support plate but also a plurality of tires not supported by the support plate but being carried upward together in the sharply inclined individual transport zone of the slat conveyor may be raised by the mixed-suspended state collapsing member which is fixedly mounted protrusively on the sliding surface section, and securely returned to the horizontal take-in zone.
