    • This invention relates to a novel cartridge-needle unit having a retractable needle for use with disposable or reusable holders to form safety syringes. The cartridge-needle unit comprises a cartridge comprising a hollow body, a septum at the distal end of the body, means for retaining the septum, and a plunger, axially and reciprocally slidable through the interior of the body; a needle capable of being withdrawn within the cartridge; a hub comprising a sleeve adapted to be snapped on the distal end of the cartridge; means for retaining the needle within the hub during an injection; and means for releasing the needle from the hub after the injection comprising an element capable of passing through the septum. The retractable cartridge-needle unit exhibits improved reliability, reduces the tendency for body fluids and/or medication to remain in an unprotected area upon retraction of the needle and virtually eliminates the possibility that the needle can be released into the patient.
    • 本发明涉及一种新颖的针筒单元,其具有可缩回的针,用于一次性或可重复使用的保持器以形成安全注射器。 药筒针单元包括一个药筒,该药筒包括中空体,身体远端的隔膜,用于保持隔膜的装置和一个可轴向和往复滑动穿过本体内部的柱塞; 能够在筒内取出的针; 毂,包括适于卡扣在盒的远端上的套筒; 在注射期间将针保持在轮毂内的装置; 以及用于在注射之后将针从轮毂上释放的装置,包括能够通过隔膜的元件。 可缩回的针筒单元表现出改进的可靠性,减少体液和/或药物在针回缩时保持在未保护区域中的趋势,并且实质上消除了针可以释放到患者体内的可能性。

    • A fuser for fusing toner images to a receiving sheet includes a pressure roller and a fusing belt. The fusing belt has leading and trailing ends. A towing device is positioned to receive both the leading and trailing ends of the belt to form an endless belt. The towing device is moved through a path which moves the fusing belt through an endless path, which path includes a fusing nip with the pressure roller. The belt is backed by a heated roller at the fusing nip which defines a portion of the endless path and cooperates with the pressure roller to provide pressure in the nip.
    • 将调色剂图像定影到接收片的定影器包括压力辊和定影带。 定影带有前端和尾端。 牵引装置定位成接收带的前端和后端以形成环形带。 牵引装置移动通过使定影带通过环形路径移动的路径,该路径包括与压力辊的定影辊隙。 皮带在定影辊隙处由加热的辊支撑,该定影辊隙限定环形路径的一部分,并与加压辊配合以在辊隙中提供压力。

    • Multicolor toner images are formed on a receiving sheet by superimposing single toner color images formed electrostatically on an image member, in registration on the receiving sheet. The receiving sheet is carried by a transfer roller repeatedly through engagement with the image member. The transfer roller is held slightly out of engagement with the image member when no receiving sheet is between the roller and image member. When a receiving sheet is between the roller and image member the roller is driven through the receiving sheet by the image member. To improve registration, the transfer roller is reindexed between transfer of each image by a stepper motor which rotates the transfer roller when no sheet is present between the transfer roller and the image member.
    • 多色调色剂图像通过将形成在静电上的单个调色剂彩色图像重叠在接收片上而形成在接收片上。 接收片材​​通过与图像构件的接合重复地由转印辊承载。 当辊和图像构件之间没有接收片材时,转印辊略微与图像构件接合。 当接收片材位于辊和图像构件之间时,辊被图像构件驱动通过接收片材。 为了改善配准,当在转印辊和图像构件之间没有纸张时,通过使转印辊旋转的步进电动机在转印每个图像之间转印辊。
