摘要： An electrically driven power steering apparatus is structured such that a large impact on a rack shaft occurs upon an impingement of a steering stopper, and, even when an axial force acting on a ball bearing of a presser member becomes zero, a rotation of the presser member is hindered by caulking c at a thin plate member. Therefore, the presser member does not slacken, and a predetermined axial force can be given again to the ball bearing when the impact dissipates. The thus structured power steering apparatus exhibiting, though the cost is low, an excellent shockproof characteristic and capable of preventing the bearing from coming off a ball screw nut, can be provided.

摘要： An electrically driven power steering apparatus is structured such that a large impact on a rack shaft (22) occurs upon an impingement of a steering stopper, and, even when an axial force acting on a ball bearing (25) of a presser member (30) becomes zero, a rotation of the presser member (30) is hindered by caulking c at a thin plate member (30b). Therefore, the presser member (30) does not slacken, and a predetermined axial force can be given again to the ball bearing (25) when the impact dissipates. The thus structured power steering apparatus exhibiting, though the cost is low, an excellent shockproof characteristic and capable of preventing the bearing from coming off a ball screw nut, can be provided.

摘要： There is provided an ultrasonic diagnostic apparatus in which ultrasonic waves are transmitted into the subject, the ultrasonic waves reflected within the subject are received to obtain received signals, and an image is produced in accordance with the received signals thus obtained, and particularly to an ultrasonic diagnostic apparatus having a function of guiding a puncture needle to be introduced into the subject. Of a scanning area formed with a number of scanning lines scanned by ultrasonic waves, within the subject, a first area including a part or a whole of a passage of a puncture needle is scanned with a scanning density higher than that of a second area, excepting the first area, of said scanning area. The ultrosound transmit-receive portion sets up the first area based on the location of the puncture needle tip as sensed by received vibrations therefrom.

摘要： An acoustic coupler, combined with an ultrasound probe, is made of a gel a part of which is hardened for providing holding means for holding the probe for lifting up the probe with the coupler and another part of which is used to form an acoustically transparent path between the probe and a surface of an object to be acoustically inspected. Poly vinyl alcohol (PVA) is a typical material for the gel, and the coupler is fabricated by molding a PVA solution by partially increasing concentration of PVA and/or a repeating frequency of refrigerating and thawing the PVA solution, compared with those for the transparent path, in a molding process of the coupler.
