C./sec; andaging the cooled titanium alloy at a temperature of 400.degree. to 600.degree. C.The superplastically formed titanium alloy can be diffusion-bonded, thereafter the diffusion-bonded titanium alloy can be cooled and aged.

An air damper capable of stabilizing a damping force of the air damper is obtained.When a rod member (16) is pulled out of a cylinder member (20), a suction member (60) hits against the other side surface (56) of a piston member (30) so as to close an air passage (28), and an airflow path communicating between an air chamber (26) and an outside is only orifice portions (42). On the other hand, when the rod member (16) is pushed into the cylinder member (20), the suction member (60) moves away from the other side surface (56) of the piston member (30) so as to open the air passage (28). Consequently, compared to a conventional structure in which an O-ring rolls by a friction force with an inner peripheral surface of a cylinder so as to open or close the air passage, the air passage (28) can be opened and closed as intended so as to be capable of stabilizing the damping force.

Provided is an embolization coil in which even if the coil is wound in a shape of a small diameter, an elongation-preventing wire is not broken and the delivery property thereof can be prevented from deterioration. An embolization coil has a coil of partial or full-pitch winding and an elongation-preventing wire which are fixed respectively at two points different from each other, and is characterized in that the natural length of the coil arranged between two different points before the coil is fixed is longer than the length of the elongation-preventing wire arranged between two different points before the elongation-preventing wire is fixed.

The magnitude of a linear damping coefficient Cs is set so as to decrease the greater a maximum amplitude value α of an intermediate frequency sprung acceleration is. In the case where a damping force control apparatus carries out control for dampening vibrations of a sprung member using a nonlinear H-infinity control theory, the linear damping coefficient Cs is set to a high value when the maximum amplitude value α of the intermediate frequency sprung acceleration inputted to a suspension apparatus is low. Accordingly, a requested damping force Freq also increases, which makes it possible to quickly dampen vibrations in the sprung member. Meanwhile, in the case where the maximum amplitude value α of the intermediate frequency sprung acceleration is high, the linear damping coefficient Cs is set to a low value. Accordingly, the requested damping force Freq also decreases, which makes it possible to suppress degradation in the riding quality when intermediate frequency vibrations are inputted, and particularly makes it possible to suppress riding quality degradation when the vibration speed is high.

Disclosed herein is a medical wire with an intracorporeally indwelling member connected to the leading end part of a conductive wire body through a thermally-fusible connecting member, wherein expected heat generation can be achieved even when a conductive member that causes leak comes into contact with the leading end part of the conductive wire body, and thus the intracorporeally indwelling member can be surely released.This medical wire comprises a conductive wire body and an intracorporeally indwelling member connected to the leading end part of the conductive wire body through a thermally-fusible connecting member, in which the connecting member is heated and fused by supplying an electric current for fusion through the conductive wire body, thereby releasing the intracorporeally indwelling member, wherein a non-conductive coating film is formed on an external peripheral surface of an electrode-forming portion in the leading end part of the wire body, and a part of the surface of the wire body is exposed through the coating film, thereby forming a heating electrode portion.

The medical catheter tube of the present invention integrally has an inner layer tube; reinforcement material layers formed by placing element wires on the inner layer tube; a marker; and an outer layer tube. The element wires, which are first and the other element wires, for forming the reinforcement material layers are synthetic resin element wires and/or metallic element wires, the first element wires are placed in the axis direction of the catheter to form the first reinforcement material layer, and the other element wires are wound in a coil form on the first reinforcement material layer, in the circumferential direction of the catheter, to cover the first reinforcement material layer. The marker is flexible to deformation. Because of the presence of the reinforcement material layer and the outer layer tube, flexural rigidity from a base section to a head section is reduced in a stepped or continuous manner.

A motor-driven bending endoscope includes a removal restriction mechanism which restricts removal of a trackball from a trackball mounting portion, and an operation section engaging portion which detachably engages an attachment/detachment portion with an operation section attachment portion at a time of coupling between the operation section attachment portion and the attachment/detachment portion when an operation section unit is attached to the operation section attachment portion. The operation section engaging portion and the removal restriction mechanism are interlockingly driven by an interlock drive mechanism. Thereby, there is provided a motor-driven bending endoscope which can reduce fatigue of the right hand at a time of performing a twisting operation of an insertion section, improve the recognizability of the up-and-down direction at a time of inserting the insertion section, and enhance the operational work efficiency.

A vehicle body communication device (200) transmits a request signal to both a wheel side sensor (31) that is provided in a valve (24) of a wheel (22), and a tire side sensor (32) that is embedded in a tire tread (28). When the wheel side sensor (31) and the tire side sensor (32) receive the request signal from the vehicle body communication device (200), respective return signals are transmitted to the vehicle body communication device (200). The respective transmission patterns are set to be different.
