摘要:
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.

A puncture instrument capable of punctured high frequency treatments. The puncture instrument essentially includes: a guide tube to be inserted into an intracavitary portion of a patient; a puncture needle member having an elongated needle body slidably received in the guide tube, and a sharp-pointed needle head provided contiguously at the fore end of the elongated needle body and protrudable out of the guide tube to penetrate into a target intracorporeal portion to be treated when the needle body is manipulated in a forward direction; and a high frequency electrode provided on a fore end portion of the needle body to be penetrated into the target intracorporeal portion together with the sharp-pointed needle head.

A catheter type ultrasound probe having an ultrasound transducer mounted on a rigid fore end section at the tip end of a soft and flexible body section of a catheter member to be introduced into an intracavitary portion. The catheter member includes an articular joint section which is connected between the rigid fore end section and the flexible body section, the articular joint section having front and rear joint members pivotally connected with each other for angular flexing movements in directions forward and rearward of an active face (a signal transmission and reception surface) of the ultrasound transducer on the rigid fore end section of the catheter member. A biasing mechanism is mounted on the articular joint section to urge a front joint member constantly rearward of the active face of the ultrasound transducer into a bent position off the axis of the catheter member along with the rigid fore end section. A joint operating wire is connected to the front joint member to turn same back into a straight axial position against the biasing force of the biasing mechanism.

A multi-plane electronic scan ultrasound probe having a rotary member rotatably mounted on a distal end portion of an elongated catheter member of the probe and support thereon an ultrasound transducer consisting of a row of a large number of ultrasound elements. The rotary member is connected to a rotation control knob on a manipulating head of the probe by way of rotation transmission wires extended through the catheter member and via a drive pulley mounted on the manipulating head in association with the rotation control knob to turn the ultrasound transducer through an arbitrary angle in multi-plane electronic scanning by manipulation of the rotation control knob. In addition, for the purpose of tilting the ultrasound transducer through a desired angle, the ultrasound probe is provided with a tilting mechanism to tilt the rotational axis of the rotary member in a predetermined direction, including a tiltable support for the rotary member, a tilt control means provided on the manipulating head, and a tilt signal transmission means for transmitting a tilt control signal from the tilt control means to the tiltable support.

A plurality of hard particles 102 is arranged in a mold 302 which suppresses movement of the hard particles 102 so as to be close to each other, and the hard particles 102 arranged in the mold 302 are fixed with resin 103, thereby forming a friction surface 101. Therefore, a pad 100a in which the plurality of hard particles 102 is arranged on the friction surface 101 can be more easily manufactured.

A recognition result extraction unit and an agreement determination unit are provided. The recognition result extraction unit extracts, from a recognition result storage unit, N best solutions A and B obtained by an utterance B. The utterance B follows an utterance A corresponding to the N best solutions A and made by a speaker b who is different from a speaker of the utterance A. In a case where a repeat utterance determination unit determines that the N best solutions B are N best solutions obtained by a repeat utterance B according to the utterance A corresponding to the N best solutions A, when the best solution A and B are different each other, the agreement determination unit determines that some or all of the N best solutions A can be replaced with some or all of the N best solutions B.
摘要:
There is provided a braking device including a pad having a friction surface, and a disc having a friction surface sliding on the friction surface. The pad includes, in the friction surface, a plurality of hard particles tilted in the opposite direction to a direction in which the friction surface slides on the friction surface, and the disc includes, in the friction surface, a plurality of hard particles tilted in the direction in which the friction surface slides on the friction surface. Thereby, mutually pressing forces between the hard particles are increased. Additionally, the mutually pressing forces between the hard particles are increased, and consequently the distance between the friction surfaces is shortened. Therefore, a higher frictional force can be obtained.
