摘要： An ultrasonic probe includes a housing, a piezoelectric element provided in the housing, the piezoelectric element emitting an ultrasonic beam, and a refracting member rotatably provided in the housing. The refracting member has a first surface opposite to the piezoelectric element and a second surface at which the ultrasonic beam emitted from the piezoelectric element and passing through the first surface is deflected in a state where a deflection angle between an axis perpendicular to a surface of the piezoelectric element and a deflected ultrasonic beam changes as the refracting member rotates.

摘要： An ultrasonic probe includes a housing, and a plurality of piezoelectric elements radially arranged in a plane substantially perpendicular to a direction in which the ultrasonic probe is inserted into a hollow portion to be scanned. The ultrasonic probe also includes an electrical part for carrying electricity to the piezoelectric elements to thereby cause the piezoelectric elements to emit ultrasonic waves and for carrying, to an external device, electric signals generated from the ultrasonic waves reflected by the hollow portion and received by the piezoelectric elements.

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.

摘要： A method of fabricating an ultrasonic coupler to a specified configuration such that the ultrasonic coupler is fabricated by freezing and defrosting an aqueous solution containing a polymer. A surface of the fabricated ultrasonic coupler is made to be smooth. The ultrasonic coupler is fabricated using an ultrasonic coupler fabricating die including members each made of silicone rubber which varies in compliance with the expansion and the contraction of the aqueous solution. To fabricate the ultrasonic coupler, the aqueous solution containing a polyvinyl alcohol (PVA) is poured into the die. Then, the die is subjected to the process of cooling to below the freezing point and the process of recovery to room temperature so as to progress a bridging of the PVA, thereby progressing a gelling of the aqueous solution.

摘要： An ultrasonic coupler to be arranged between an ultrasonic probe and a patient to be examined using an ultrasonic diagnostic apparatus is provided. A method of producing the ultrasonic coupler is also provided. The ultrasonic coupler is made of a gel material having no tackiness. According to the present invention, an ultrasonic coupler includes the gel material which contains polyvinyl alcohol in the range of 3 weight % to 6 weight %. The polyvinyl alcohol is at least 98.0 mole % in the degree of saponification, and the gel material has a hardness in the range of 0.5.times.10.sup.4 dyne/cm.sup.2 to 2.times.10.sup.4 dyne/cm.sup.2. A coupling member for holding the ultrasonic coupler in contact with the ultrasonic probe is fixed to the gel material. The method of producing the ultrasonic coupler includes a step of providing a mold having an interior chamber. A coupling member projects into the interior chamber, and has an attachment portion inserted into the mold. The attachment portion has a shape adapted for fitting on the ultrasonic probe. An aqueous solution is injected into the interior chamber. After the injection, at least one operation of freezing and defrosting the aqueous solution is performed, thereby transforming the aqueous solution into a gel material. Finally, the mold is separated from the gel material while allowing the coupling member to be embedded in the gel material with the attachment portion protruding from the gel material.

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.
