摘要： A print head for a serial dot matrix printer comprising a sandwich structure including a base plate, a segmented-ring magnet, a print hammer disc and face plate is disclosed. The segmented-ring magnet comprises a ring formed of a magnetic material having spaced apart, magnetized, regions (segments). The print hammer disc is formed of a magnetically permeable, resilient material and has a plurality of inwardly projecting arms (hammers), each of which is aligned with a magnetized segment. Mounted on the hammers are print blades, which are aligned with radial slots formed in the face plate. Each print blade includes a dot-printing tip that projects orthogonally outwardly from the blade, and lies in a central aperture in the face plate. Mounted on the base plate, in line with each hammer, is a post having a coil mounted thereon. When the coils are de-energized, the magnetic field formed at the tips of the posts is adequate to overcome the spring force of the related hammer, whereby the air gap therebetween is closed and the hammer is cocked. Energization of any coil by a pulse of appropriate polarity and magnitude cancels the magnetic pull created by the related magnetic segment and allows the related hammer to pull away from the related post. This action creates a dot as the released spring force causes the dot-printing tip of the related print blade to press a print-producing material (e.g., a ribbon) against a print receiving medium (e.g., a sheet of paper). Rather than defining a single column, the dot-printing tips define two or more columns.
摘要翻译：公开了一种用于串行点阵式打印机的打印头，其包括包括基板，分段环磁体，打印锤盘和面板的夹层结构。分段环磁体包括由具有间隔开的磁化的区域（段）的磁性材料形成的环。打印锤盘由可渗透的弹性材料形成，并且具有多个向内突出的臂（锤），每个臂与磁化段对准。安装在锤子上的打印刀片与形成在面板上的径向槽对齐。每个印刷叶片包括从叶片正交向外突出并位于面板中的中心孔的点印刷端头。安装在基板上，与每个锤子一致，是具有安装在其上的线圈的柱。当线圈断电时，形成在柱的顶端处的磁场足以克服相关锤的弹簧力，由此其间的气隙被封闭并且锤子被起动。通过适当极性和大小的脉冲对任何线圈的通电消除由相关磁段产生的磁拉，并允许相关的锤从相关的柱上拉开。当释放的弹簧力导致相关打印刀片的点印刷尖端将印刷产生材料（例如，色带）压靠在打印接收介质（例如，一张纸）上时，该动作产生点。点阵打印提示不是定义单个列，而是定义两列或更多列。

摘要： Medical devices that include oxidizable portions can be plated after a two step activation process that includes successive applications of two aqueous solutions of ammonium bifluoride. Once plated, such materials can be soldered using conventional solders and fluxes. Medical devices can be assembled by soldering together plated materials. Oxidizable materials can be plated with radiopaque materials to yield medical devices that are more visible to fluoroscopy.

摘要： Disclosed are methods and structures for joining metallic members. A welding material can be used between two metallic members that comprise different metals. The different metals can normally form brittle intermetallic compounds when welded to one another, and the welding material can inhibit the formation of the brittle intermetallic compounds.

摘要： A system for recanalizing an occluded blood vessel including a centering catheter employed to center an ablative guide wire within the blood vessel as the guide wire traverses the occlusion. The centering catheter includes a catheter body with an operative lumen through which the ablative guide wire is slidingly disposed. The centering catheter further includes a distally disposed centering mechanism that, when activated, centers the ablative guide wire within the blood vessel as it traverses the occlusion. The centering mechanism can comprise various embodiments including a single inflatable balloon or segmented inflatable balloon, which is in fluid communication with an inflation lumen. An airless preparation lumen may be disposed within the inflation lumen for ease of centering catheter preparation. The ablative guide wire includes insulation that is preferably formed of heat shrink tubing, which is stretched prior or concurrently with the heating process. The ablative guide wire includes a distal ablation tip having a non-traumatic structure and at least one discontinuous feature for creating high current densities for more efficient tissue ablation.

摘要： An atherectomy burr having an operating diameter that is larger than the diameter of a catheter in which the burr is routed. The burr may include a flexible polymeric tube that is plated with an abrasive and that expands when the burr is rotated. Metal fibers are embedded into burr to improve strength and to control the maximum expansion diameter of the burr. The abrasive is plated on the burr by first selectively exposing the underlying metal. The exposed metal is then plated with a layer of metal such as nickel having a slurry of diamond particles disposed therein using an electro and/or electroless plating method. When the burr is rotated, the polymeric tube expands by centrifugal force to ablate a new lumen in the patient's vessel.

摘要： An atherectomy device that may reduce the risk of damage to a vessel wall. One rotatable atherectomy burr has a recessed material removal portion lying between less abrasive proximal and distal shoulders. The shoulders can have a straight, rounded or elliptical taper. The shoulders can perform a cam action when the burr is canted is a vessel, as when passing the burr and guide wire through a tortuous, stenosed vessel path. The shoulders act to align the burr with the path through the vessel, presenting the less abrasive shoulders to the vessel wall while presenting the abrasive portion to a stenosis.
