"A method of making a current sensor is described. The method includes providing a leadframe having a current conductor portion comprising two sections shaped such that a current to be measured flows in directions oriented obliquely or oppositely with respect to each other. Further, the method includes deforming the leadframe to lower the current conductor portion, and mounting an isolator on the current conductor portion. The method also includes mounting a semiconductor chip having a thickness of at least 0.2 mm and comprising two magnetic field sensors composed of four Hall sensors and magnetic field concentrators on the isolator, connecting the semiconductor chip and sensor terminal leads by wire bonds, packaging the semiconductor chip and parts of the leadframe in a plastic housing, and cutting a frame of the leadframe from current terminal leads and the sensor terminal leads."

「【課題】求められる要件を満足させる電流センサを得るための電流センサ作製方法を提供する。【解決手段】２つのセクションを含む電流導体部７を有するリードフレームを設け、２つのセクションは、測定される電流が互いに対して斜めにまたは対向して配向される方向に２つのセクションにおいて流れるように成形し、リードフレームを変形させて前記電流導体部７を低下させ、アイソレータ２を電流導体部７に取り付け、少なくとも０．２ｍｍの厚さを有し、かつ、４つのホールセンサおよび磁場集中器１６で構成される２つの磁場センサを含む半導体チップ３をアイソレータ２に取り付け、ワイヤーボンド１７によって半導体チップ３およびセンサ端子リード６を接続し、半導体チップ３、およびリードフレームの部品をプラスチック製ハウジング４にパッケージし、リードフレームのフレームを電流端子リード５およびセンサ端子リード６から切り離す」

"An apparatus has a syringe housing. A plunger has a shaft, wherein the plunger is slidably received within the syringe housing between a first and second position（＊同一名称複数部材の修飾、冠詞の謎）. A Hall sensor is disposed within the shaft and a magnet is fixed proximate the syringe housing."

「本発明の装置は、シリンジハウジングを有する。プランジャはシャフトを有し、プランジャは、第１位置と第２位置との間でシリンジハウジング内において滑動可能に受け入れられる。ホールセンサはシャフト内に配置され、磁石は、シリンジハウジングに近接して固定される」

[0086] The diversion reservoir 1404 is designed to accommodate flow of medium from the flow diverter assembly 1402, to collect and hold such medium and then, if desired, urge such collected medium back into the system for use in delivering additional medium to the patient via injection catheter 1428. In one embodiment to accomplish this end, diversion reservoir 1404 may include an elastic expansion tube 1516 disposed about through-tube 1506. As seen in FIGS. 15C and 15D, expansion tube 1516 extends along a portion of a length of through-tube 1506. Expansion tube 1516 may be formed of silicone (or like flexible) material sealably secured adjacent each end thereof about the through- tube 1506 by first and second retention washers（＊ここではちゃんと複数）1518 and 1520, respectively, or by other suitable sealable and mechanical fastening arrangements. An outer surface of the through- tube 1506 may include interference elements such as surface features or an annular interference rim 1506a (see FIG. 15C) to further facilitate the sealing of the expansion tube 1516 to the through-tube 1506 via the retention washer 1518 and 1520.
