Title: 改良された締結具を備えたパイプクランプ
IPC: F16L33/04
Filed: 2005-11-21
Abstract: バンドおよびナットと、ボルトの締結具とを有するバンドクランプ。バンドは、ボルトを受けるための開口部をそれぞれ有する、半径方向に延びる対向するフランジを含む。ボルトは、首部と、ナットを受けるためのねじ本体部と、首部からねじ本体部までテーパの付いた中間部とを含む軸部を有する。一実施形態において、テーパの付いた中間部は、首部の一部分が本体と共通表面を有するように、軸部のまわりに部分的にのみ延びる。締め付ける間に、フランジの開口部の半径方向内側の接面はねじ本体部を係合することができ、テーパの付いた中間部を横切り上に乗る必要なく、ねじ本体部に沿って共通の表面をわたって首部に滑動することができる。別の実施形態において、ナットは、ナットがボルト上に所望の軸方向に締め付けられるとテーパの付いた中間部を係合する、角度のある肩部を有する。

Title: ヘッド位置を用いたディスク記憶空間アドレス指定
IPC: G11B20/10
Filed: 2005-11-25
Abstract: 現在のＢＤ規格は、ＡＤＩＰ内にアドレスは２１ビットで表現され、１９ビットは対応するＲＵＢ番号を指示し、２ビットは、ディスク上のデータの最も小さいアドレス可能な部分である一のＲＵＢに対応する２つの連続するＡＤＩＰ内に連続して００，０１，１０に設定されることを、規定する。これから、記憶空間のせいぜい３２．２ＧＢがアドレス指定できることが導かれる。しかし、近年の開発に起因して、レイヤー当たり３５ＧＢの記憶容量が達成しうる。本発明によれば、一以上のビットが、アドレスを表すために現に割り当てられる２１ニットに付加される。しかし、この追加のビットは、ＡＤＩＰ内に記憶されずに暗黙のまま残され、現在のＢＤ符号化規則からの大きな逸脱が免れる。追加のビットは、対応するＲＵＢが存在する場所の情報媒体上の位置に基づいて装置により再構成される。
