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).

A pomegranate juice with enhanced estrogen-like activity per unit amount, a pomegranate juice powder, a process of producing the powder, and foods, feeds, pharmaceutical compositions and the like containing the powder. 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.
摘要:
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.
摘要:
A method for preparing N-acetylneuraminic acid characterized in reacting N-acetylglucosamine with pyruvic acid in an alkaline condition by the action of N-acetylneuraminic acid lyase.
摘要:
The present invention provides a process for preparing neuraminidase comprising incubating a mutant of the genus Arthrobacter capable of producing neuraminidase in the absence of any inducing substance, and recovering neuraminidase from the resulting culture.
摘要:
This invention provides a process for producing N-acylneuraminate aldolase comprising incubating a mutant of the genus Escherichia capable of producing N-acylneuraminate aldolase even in the absence of any inducing substance, and collecting N-acylneuraminate aldolase from the resulting culture.
摘要:
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.
