Title: ソケットケーシングとソケットインサートとの間の連結部材を有する股関節ソケット
IPC: A61F2/30
Filed: 2000-01-13
Abstract: (57)【要約】
ソケットケーシングと該ソケットケーシング内に嵌め込み可能なセラミック製のソケットインサートとから成る股関節ソケットにおいては、両構成要素の接合面は正確に加工されねばならない。それというのも、不精度が生じた場合にソケットインサート内で、構成部材の強度を減少せしめる不均一な応力集中が生ずるからである。手術に起因して生ずる汚染物が締付け結合の耐久性を低下させる。この理由から、セラミック製のソケットインサートと金属製のソケットケーシングとの間に力伝達を均一化するための手段が設けられている。プラスチック製の層、特にポリエチレン製の層は公知である。いずれにせよポリエチレン製の連結部材の欠点は、常温流れ耐性ではないということにある。更に、連結部材とソケットケーシングとの間で相対運動が生じて、これにより摩滅が生ずることがある。それ故本発明では、股関節ソケットのソケットケーシングとソケットインサートとの間に嵌め込まれた連結部材が提案され、該連結部材の弾性及び緩衝特性が、該連結部材の多孔性及び連結部材の表面の構造によって予め規定可能である。

Abstract: A stent made of metallic and/or non-metallic material that can be implanted into tubular structures or other body cavities is coated with nanoscale particles that consist of a paramagnetic core and at least one shell adsorbed to it which is durably bonded to the stent surface. This coating makes it possible to selectively and homogeneously heat up the implant by applying an alternating magnetic field with a clinically tolerable combination of field strength and frequency, thereby achieving high power absorption and, on the one hand, a temperature level that enhances the growing-in of the implant by enhancing cell proliferation, on the other hand, a temperature range in which a restenosed implant can be regenerated. Also, it facilitates position detection.

Title: Semiconductor device
Inventor: SAYAMA YASUYUKI
IPC: H01L29/861
Filed: 2001-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a PIN diode which can solve the problem raised by the conventional PIN diode of the area of the PIN junction of the diode having to increase at the lowering of the high-frequency series resistance of the diode, because the P+-type region of the diode is continuously provided on the surface of an I layer, and, in addition, when the P+-type area is increased, the chip size of the diode expands and the volume of the diode increases and, consequently, the high-frequency characteristic of the diode is worsened. SOLUTION: The area of the PIN junction of the PIN diode can be gained on the side faces of subdivided P+-type regions, by selectively constituting the P+-type region of arranged adjacent to grid- or island-like regions. Since only the area of the PIN junction is increased by only subdiving the conventional P+-type region, the chip size of the diode will not change from the conventional size and, in addition, the series resistance of the diode when a forward bias voltage is impressed upon the diode can be reduced, while the conventional junction capacitance is suppressed by coupling depletion layers with each other, by reducing the interval between adjacent P+-type regions.
