    • An ultrasound probe with a needle guide passage for a puncture needle, the ultrasound probe having an ultrasound transducer mounted on a girder portion of a rigid fore end section at the distal end of a flexible insert section of a catheter member to be introduced into an intracavitary portion, and a needle passage provided axially within the catheter member for launching the puncture needle therethrough. The needle passage is turned toward an exit opened on a lateral side portion of the rigid fore end section at a position on the near side of the ultrasound transducer. The rigid fore end section of the catheter member is provided with a bent portion which is turned off the axis of the catheter member through a predetermined angle in a direction away from a needle launching direction of the needle passage at a position on the near side of the exit opening of the needle passage.
    • 一种具有用于穿刺针的针引导通道的超声探头,所述超声波探头具有安装在导管构件的柔性插入部分的远端处的刚性前端部分的梁部分上的超声换能器以被引入腔内 以及轴向设置在导管构件内的针通道,用于将穿刺针穿过其中。 针通道在超声波换能器的近侧的位置处朝向刚性前端部的侧面部分开口的出口转动。 导管构件的刚性前端部设置有弯曲部,该弯曲部在远离针通道的针发射方向的方向上以预定角度离开导管构件的轴线,位于近侧的位置 针通道的出口。

    • A friction couple including a frictionally rubbing member that contains at least one of a binder and a filler, in which the binder and the filler have a modulus of elasticity of 1 GPa or higher and 15 GPa or lower, no softening point or no glass transition point in the range of −50° C. or higher and 200° C. or lower, and a compressive strength of 50 MPa or higher at 25° C. and 25 MPa or higher at 200° C.; and a frictionally rubbed member. The ratio of the maximum value tan δ(Max) to the minimum value tan δ(Min) of the loss tangent tan δ of the frictionally rubbing member obtained through a dynamic viscoelastic measurement performed at a frequency of 0.1 Hz or higher and 20 Hz or lower and in the range of −50° C. or higher and 250° C. or lower after thermoforming is 5 or less.
