Patent JP-2003508707-A (JP)
IPC: F16H29/02
Filed: 1999-09-29
Abstract: A transmission utilizes oscillating torque to vary the mechanical power transmitted to a load. An arm assembly is rotatably coupled to a frame. At the ends of the arms are eccentric masses, rotatably coupled thereto. An input shaft rotates the masses about the ends of the arms. The rotating masses produce an oscillating torque that causes the arms to oscillate. The arms are coupled to an output assembly. The output assembly utilizes one way clutches, with one clutch reversed relative to the other clutch. The one way clutches convert the bidirectional rotation of the arms to unidirectional rotation for the load. The output speeds of the transmission are controlled by providing at least two side by side rotatable masses and varying the phase of one of the masses relative to the other mass. Varying the phase changes the center of gravity of the masses, thereby affecting the torque applied to the arms.

Title: 溶融金属混入物センサープローブ
IPC: G01N15/10

Abstract: (57)【要約】
本発明は、溶融金属（１２）が通過するセンシング通路（２６）を持ち、二つの電極（２０，２８）の間の通路を通って直流電流の経路が形成されている溶融金属混入物センサープローブを提供することである。通路（２６）内にある中心のセンシングゾーンを通る混入物（７２）の経路は電流路上の電気抵抗を変え、それのサイズを示す検出可能なパルスを発生し、サンプル中の微粒子の数をカウントすることを可能にする。従来、通路は、スムーズなフローを得るための円錐形の入口の有無にかかわらず円筒形であるか、通路の口部の材料を熱することによってつくりだされた任意のスムーズなプロファイルのものであった。流動する金属は、電流があるしきい値以上になるとき自己誘導磁界と「条件調整」フローを生じる電磁力を発生する。高いレベルの背景ノイズはパルス検出を困難にするので、フロー断面積をその入口（６２）からセンシングゾーンへとスムーズに減らすように機械加工することによって、好ましくは放物線か楕円のプロファイル（５６）とすることによって、動作を改善することが提案されている。好ましくは、出口（６８）は同じプロファイルを持つ。更なる改善は、壁表面（５６）を１.０１６マイクロメーター（４０マイクロインチ）よりもよい平滑度に機械加工することによって得ることができる。このような精密でスムーズな壁面を持つ通路は必要な最良のテストならびに条件調整電流についてシステムのデザインを容易にするものである。
