Hydro-viscous variable speed clutch transmits torque by means of viscous fluid between the friction discs. The study of temperature distribution on friction disc plays a very important role for the design of hydro-viscous soft-start device. When the grooves on the driving friction disc surface have more complex shape, the analytic solution of the temperature field is difficult to obtain. By the advantage of the periodicity of geometric dimension along the circumferential direction of the driving friction disc, physical model with radial and annular groove is simplified and built. FLUENT software is used to make a simulation analysis on the temperature field of the friction disc, transient and steady state temperature distribution is obtained which provides a new approach to the analysis of the temperature field of the friction disc with complex grooves.

Illuminating System

On account of its high brightness, the field emission electron source has the advantage that it provides the conventional electron microscope with highly coherent illuminating system and that it directly improves the, resolving power of the scanning electron microscope. The present authors have reported some results obtained with a 100 kV field emission electron microscope.It has been proven, furthermore, that the tungsten emitter as a temperature field emission source can be utilized with a sufficient stability under a modest vacuum of 10-8 ~ 10-9 Torr. The present paper is concerned with an extension of our study on the characteristics of the temperature field emitters.

The versatility of Low Temperature Field Emission SEM (LTFESEM) for viewing frozen-hydrated biological specimens, and the high resolutions that can be obtained with such instruments have been well documented. Studies done with LTFESEM have been usually limited to the viewing of small organisms, organs, cells, and organelles, or viewing such specimens after fracturing them.We use a Hitachi 4500 FESEM equipped with a recently developed BAL-TEC SCE 020 cryopreparation/transfer device for our LTFESEM studies. The SCE 020 is similar in design to the older SCU 020 except that instead of having a dedicated stage, the SCE 020 has a detachable cold stage that mounts on to the FESEM stage when needed. Since the SCE 020 has a precisely controlled lock manipulator for transferring the specimen table from the cryopreparation chamber to the cold stage in the FESEM, and also has a motor driven microtome for precise control of specimen fracture, we have explored the feasibility of using the LTFESEM for multiple-fracture studies of the same sample.
