我们研制了一种中央处理机(CPU)和外设备之间的光纤传输小型计算机接口。数据字长20bit,传输速率10Mbit/s。光缆由20根突变光纤组成,可长达120米。把光电转换器件(即LED和单片集成光电二极管接收器)装配在配线的有源连接器里并牢固地固定好相应的光纤端子。连接器的插针导通TTL信号。这种光接口比通常的电接口体积小得多。在该计算机系统中,接口和设备之间用多芯导线连接,它们包括多脚连接器,驱动器、接收器集成片以及印刷电路板(PC)。通常五个IC中有一个是接口电路。这些连

山西化工 1984年第3期 53-57+17页

作者： h.schmidt Traub.E.Goeke 马月明

气流床气化的特点是:煤和气化剂并流加入。粉煤的粒度小于0.1毫米,而氧与蒸汽的比例可高达20/1。气化温度总是高于灰渣熔点,所有煤种(包括焦炭和木炭)均可适用。目前,工业规模装置的气流床只有Koppers—Totzek法,它是在常压下操作。Sh.l... 详细信息

Th. GP130 cytokine receptor subunit encoded by IL6ST is th. sh.red receptor for ten cytokines of th. IL-6 family. We describe a h.mozygous non-synonymous variant in IL6 ST(p.R281 Q) in a patient with.craniosynostosis and retained deciduous teeth. We ch.racterize th. impact of th. variant on cytokine signaling in vitro using transfected cell lines as well as primary patient-derived cells and support th.se findings using a mouse model with.th. corresponding genome-edited variant Il6 st p.R279 Q. We sh.w th.t h.man GP130 p.R281 Q is associated with.selective loss of IL-11 signaling with.ut affecting IL-6, IL-27, OSM, LIF, CT1, CLC, and CNTF signaling. In mice Il6 st p.R279 Q lowers litter size and causes facial synostosis and teeth.abnormalities. Th. effect on IL-11 signaling caused by th. GP130 variant sh.ws incomplete penetrance but ph.nocopies aspects of IL11 RA deficiency in h.mans and mice. Our data sh.w th.t a genetic variant in a pleiotropic cytokine receptor can h.ve remarkably selective defects.
