摘要： A transmitter comprises a housing, an electronics assembly, an inner cover, and an outer cover. The electronics assembly includes an actuatable switch and fits within an open-ended cavity in the housing. The inner cover is positionable over the open end to cover the electronics assembly and has a deflectable button portion which is alignable with the actuatable switch and accessable from the open end while the electronics assembly is energized. The inner cover is electrically conductive and has a sleeve which frictionally mates with electrically conductive walls of the housing to shield the electronics assembly from electromagnetic interference (EMI). The inner cover is preferably an insulating molded plastic part with a thin metallic coating.

摘要： A transmitter coupled to a control loop which carries a loop current senses a process variable which is transmitted over the loop. Circuitry in the transmitter presents an effective capacitance C.sub.eff to the control loop. The transmitter includes an isolation network coupled between the circuitry and the control loop which prevents discharge of energy stored in capacitance C.sub.eff into the control loop.

摘要： A roller cleaning apparatus for retrofit installation in a photocopier fuser assembly having a housing and a fuser roller mounted in the housing. The apparatus may comprise a mounting strip adapted to engage a surface within the housing, a pair of resilient brackets spaced apart on the mounting strip, and a cleaning roller. Each of the resilient brackets has a bearing portion, and the cleaning roller is disposed between the pair of resilient brackets. The cleaning roller has a pair of opposing ends, each rotationally mounted in one of the bearing portions. The resilient brackets are configured so as to bias the cleaning roller against the fuser roller when the mounting strip is engaged with the housing. Also, a method for installing a roller cleaning apparatus in a photocopier fuser assembly.
摘要翻译：一种用于在复印机定影组件中进行改进安装的辊清洁装置，其具有安装在壳体中的壳体和定影辊。该装置可以包括适于接合壳体内的表面的安装条，在安装条上间隔开的一对弹性支架和清洁辊。每个弹性支架具有支承部分，并且清洁辊设置在该对弹性支架之间。清洁辊具有一对相对的端部，每个相对端部旋转地安装在一个轴承部分中。弹性支架被构造成当安装条与壳体接合时将清洁辊偏压抵靠定影辊。另外，一种在复印机定影组件中安装滚筒清洁装置的方法。

摘要： A power tool in the nature of an impact tool in which a quick release mechanism for retention, and selective quick release of an accessory is provided. The quick release mechanism is actuated by a release pin disposed beneath the surface of the tool so as to be out of harms way, and actuation of the quick release mechanism is achieved by digital depression of the pin which in turn releases a latch engaging the accessory, permitting its removal from the tool.
摘要翻译：一种冲击工具性质的电动工具，其中提供用于保持的快速释放机构以及附件的选择性快速释放。快速释放机构由设置在工具表面下方的释放销致动，以便脱离危险的方式，并且通过销的数字按压来实现快速释放机构的致动，该销又进而释放与附件相啮合的闩锁，允许从工具中取出。
