Abstract: In a rotary piston machine with a casing (22) wherein there is mounted a substantially circular rotor (12) containing a plurality of sealed pistons or sliding parts (14) guided between the rotor and the casing, the guiding of the sliding parts is effected by a guiding device arranged inside the rotor with a guiding element (16) of a polygonal shape or with rods, or by a guiding device located substantially outside the rotor, with guiding cams on the cover and the bottom of the casing, which are coupled with the sliding parts in the rotor. The rotor may have in its cylindrical wall a combustion chamber between at least one pair of neighbouring sliding parts. The casing may have one or a plurality of crescent-shaped curvatures which are used as suction or explosion chamber. The device driving - or driven by - the machine may operate in an electromagnetic mode, the rotor forming the armature and the casing forming the stator of a rotating electric machine. This is particularly the case when using the present machine as a pump for toxic or dangerous liquids. The winding of the stator may also be arranged in the cover and the bottom of the center and the rotor is then formed in this embodiment with a flat air-gap.

Abstract: A single source predeposition is required to concurrently form a base diffusion profile and p+ profile. For [a] boron doped silicon semiconductor devices this can be accomplished by depositing a silicon nitride layer (34) directly over a boron source glass layer (32). After opening windows (36,36') to the underlying silicon (10), diffusion in a wet oxide atmosphere results in formation of a resulting oxide (40) in the windows with expenditure of boron by diffusion into this oxide as well as diffusion into the underlying substrate at a reduced concentration. In adjacent areas masked by the silicon nitride the boron source diffuses unidirectionally into the substrate yielding a maximum dopant concentration.

Abstract: Device for the determination of the stress relaxation under compressive loads of elastomeric materials. A test specimen (48) of the elastomeric material is held compressed to a predetermined degree (e.g. 25%) in a specimen clamp (16) between two compressing elements (44, 45). A number of specimen clamps is placed by turns under a pressure rod (23), which each turn is pressed on the upper compressing element (44) and in this way subjects the test specimen to a small additional compression, which is limited by a spacer sleeve (24) coaxial with the pressure rod. The force required for this is measured by means of a force transducer (25) mounted in the pressure rod (23); the stress relaxation is the percent decrease of this force within a certain time, e.g. a week. The specimen clamps can be kept at a predetermined temperature during the test.
