  • Patent number: 9474532
    Abstract: An embolic coil configured in such a manner that the risk that a stretch preventing wire breaks is very small even if the embolic coil is wound to a diameter smaller than the diameter of a secondary shape of the coil imparted thereto and also in such a manner that the embolic coil has excellent deliverability. An embolic coil is configured in such a manner that a stretch preventing wire and a coil, a part or the whole of said coil being coarsely wound, are affixed to each other at at least two different points. The portion of the stretch preventing wire which is located between the two different portions is provided with a portion to which a stretchable shape has been imparted.

  • Publication number: 20160254378
    Abstract: According to this GaN-based HFET, resistivity ? of a semi-insulating film forming a gate insulating film is 3.9×109 ?cm. The value of this resistivity ? is a value derived when the current density is 6.25×10?4 (A/cm2). By inclusion of the gate insulating film by a semi-insulating film having a resistivity ?=3.9×109 ?cm, a withstand voltage of 1000 V can be obtained. Meanwhile, the withstand voltage abruptly drops as the resistivity of the gate insulating film exceeds 1×1011 ?cm, and the gate leak current increases when the resistivity of the gate insulating film drops below 1×107 ?cm.

  • Patent number: 8945024
    Abstract: Disclosed herein is a medical wire with an intracorporeally indwelling member connected to the leading end part of a conductive wire through a thermally-fusible connecting member, wherein the contact of the leading end part of the conductive wire with the intracorporeally indwelling member can be surely prevented even when the connecting member is deformed. The medical wire comprises a conductive wire and an intracorporeally indwelling member connected to the leading end part of the conductive wire through a thermally-fusible connecting member, in which the connecting member is heated and fused by a high-frequency current supplied through the conductive wire, thereby releasing the intracorporeally indwelling member, wherein a non-conductive spacer for preventing the contact of the intracorporeally indwelling member with the conductive wire is provided between them.

  • Patent number: 8914193
    Abstract: The magnitude of a linear damping coefficient Cs is set so as to decrease the greater a maximum amplitude value ? 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 ? 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 ? of the intermediate frequency sprung acceleration is high, the linear damping coefficient Cs is set to a low value.

  • Patent number: 8843274
    Abstract: A suspension apparatus 1 includes an electric shock absorber 30 having a motor 40 and a ball screw mechanism 35, an electric circuit 101, an inverting amplification circuit 120, and an inertia compensation capacitor Cp. The electric circuit 101 electrically connects the two electricity supply terminals of the motor 40. The inverting amplification circuit 120 is connected to the electric circuit 101. The inertia compensation capacitor Cp is connected to the output terminal O of the inverting amplification circuit 120. As a result of approaching or separating motion between sprung and unsprung members, not only a generated current but also an inertia corresponding current Im which represents an inertial force of a rotation body, such as the ball screw shaft 36 and the rotor of the motor 40, flows through the motor 40 and the electric circuit 101. A current Ip which is antiphase to the inertia corresponding current Im flows through the inertia compensation capacitor Cp.

  • Patent number: 8657085
    Abstract: 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.

  • Patent number: 8596430
    Abstract: An electrical shock absorber 20 of the present embodiment includes a motor 21, which is rotated by approaching and separating motions between sprung and unsprung members which approach and separate from each other; and an electric circuit 50, which connects the electric terminals of the motor 21 so as to cause current to flow through the motor 21. The electric circuit 50 includes P-channel JFETs 56, 60. The gate of the P-channel JFET 56, 60 is connected to one electric terminal of the motor 21, and the source of the P-channel JFET 56, 60 is connected to the other electric terminal of the motor 21. Therefore, the induced voltage is applied to the gate. The induced voltage represents the stroke speed of the electrical shock absorber 20. Therefore, the gate voltage VGS is changed on the basis of the above-mentioned relative speed such that the gate voltage VGS increases with the stroke speed of the electrical shock absorber 20.
