摘要： A catheter having a sensor for detecting forces acting on its distal end includes a catheter tube, a chamber defined in the catheter tube. The chamber is filled with silicon gel. The catheter also has a sensor chip and a cap. The sensor has a pressure sensing surface and a backside. The cap transmits the forces acting on the distal end of the catheter tube to the pressure sensing surface of the sensor chip. Further, the catheter has a pressure introducing hole. The pressure introducing hole transmits the forces acting on the periphery of the catheter tube to the backside of the sensor chip. The sensor chip issues signals externally in accordance with the pressures transmitted to its pressure sensing surface and its backside.

摘要： A method and apparatus for the direct heat treatment of medium- to high-carbon steel rods which provides an increased tensile strength and drawability by subjecting hot-rolled steel rods to controlled cooling with a coolant. Expanded spiral coils of hot-rolled medium- to high-carbon steel rod having an austenitic structure and which is continuously transported in a generally horizontal direction is cooled by passing the spiral coils through a vessel containing a coolant of a gas bubble-water mixed fluid under a strong turbulent action. The coolant fluid contains a uniform dispersion of oxidizing gas bubbles and is maintained at a temperature of not higher than 95.degree. C. Preferably, the coolant is caused to flow in the same direction as the direction of movement of the coil in the vessel. The surface of the rod may be oxidized by allowing it to cool in air before it is immersed in the coolant fluid.

摘要： A two-axis yaw rate sensor (1) includes a vibration ring (15) and a ring support plate for supporting the vibration ring (15). The vibration ring (15) includes first to fourth vibrating drive surfaces (16a-16d) arranged in turn in a circumferential direction and narrow portions (17) located between the adjacent drive surfaces (16a-16d). The first and the third drive surfaces (16a, 16c) are opposed to one another on the axis Y passing through the center of the vibration ring (15). The second and the fourth drive surfaces (16b, 16d) are opposed to one another on the axis X passing through the center of the vibration ring (15). The axis Y is substantially perpendicular to the axis X. A PZT film (15) is formed on the drive surfaces (16a-16d) and vibrates the drive surfaces (16a-16d) in a radial direction of the vibrating ring (15). A weight (21) is coupled to a coupling portion (22) of each drive surface (16a-16d) and vibrates in a direction substantially perpendicular to the vibrating direction of the vibrating surfaces (16a-16d). Detection electrode films (24a-24d) are formed on the coupling portions (22) and detect the deformation of the corresponding coupling portions (22).
