The rolling bodies circulate and roll while being in contact with the inner-surface's operation surfaces and the outer-surface's operation surfaces.

In other words, angle between working surfaces of electrodes is 130- 152°.

The rolling bodies circulate and roll while being in contact with the inner-surface's operation surfaces and the outer-surface's operation surfaces.

A projection display is provided having visible surfaces and concealed surfaces during normal operation.

Internal tilt compensation allows the operation of the mouse on uneven surfaces.

The shape and relationship of these complementary surfaces provide for improved operating characteristics.

The purpose of this invention is to increase the operation efficiency of the heat-exchange surfaces, to increase the operation duration of thermal devices between maintenance operations and to provide an improved operation safety.

The same pressure fluid fed to the axial bearing acts on the contact surfaces and on working pressure surfaces of the pistons.

Said liquid material is urged, during operation, towards both said heat transferring surfaces.

In other words, angle between working surfaces of electrodes is 130- 152°.

This method will have great application in functionizing or bio-functionizing particulate surfaces.

The secondary contact surfaces are not engaged during a normal operating condition.

The invention relates to a bearing segment (1) for a strained hydrodynamic axial plain bearing, especially for an electric machine such as a hydro generator, comprising two subassemblies that are movable relative to each other.

Fine running clearances are defined between the front and rear surfaces of the impeller (18) and the adjacent surfaces of the casing (10) and the backliner (28).

The surfaces of cooking appliances heat up during use.
