Abstract: The present invention relates to a control rod for a nuclear plant. The control rod is arranged to be provided in a fuel assembly of the nuclear plant and to be in contact with cooling water. The control rod comprises at least an inner space which is adapted to receive an absorber material for allowing absorption of neutrons during operation of the nuclear plant. The absorber material allows formation of at least one gaseous substance during said absorption process. The control rod comprises at least a filter member having a material structure which allows passage of the gaseous substance out from the space at the same time as the material structure prevents a passage of surrounding cooling water into the space.

Abstract: A clamshell phone with two movable housing parts and can assume a closed position, in which the sound openings are covered, and an open position, in which the sound openings are exposed. According to the invention the two housing parts, when in the closed position, define, together with the speaker transducer, a closed cavity with a tube connecting the cavity to the ambient air. This arrangement makes it possible for a communications unit to use the speaker transducer both for reproducing the speech from the teleconversation partner with high quality, and for generating a loud alerting signal and also for reproducing the speech from the teleconversation partner with a sound level that is high enough to be perceived by one or more listeners at a distance from the unit. The invention is useful in mobile phones, cordless and wired telephone handsets.

The contact layer includes a film including a multielement material with equal or similar composition as any of a layered carbide or nitride that can be described as Mn+1AXn, where M is a transition metal or a combination of a transition metals, n is 1, 2, 3 or higher, A is an group A element or a combination of a group A element, element and X is Carbon, Nitrogen or both.

Abstract: A microphone circuit includes a first microphone, a second microphone, an adjustable delay unit, and a combiner. The first microphone generates a first microphone signal that includes a contribution associated with an output signal that is generated by a loudspeaker in response to an input signal. The second microphone generates a second microphone signal that includes a contribution associated with the output signal from the loudspeaker. The adjustable delay unit delays the second microphone signal relative to the first microphone signal by a delay value. The combiner combines the delayed second microphone signal and the first microphone signal to provide a combined microphone signal. The adjustable delay unit adjusts the delay value so as to reduce at least a portion of the contribution to the combined microphone signal that is associated with the output signal from the loudspeaker.

Said means comprises a member (7) being of a material having a higher dielectric constant than the material of said active part and applied next to at least a portion of said active part where a high electric field occurs when a high voltage is applied across the device for obtaining a field grading for a condition of changing of said voltage.

Abstract: A photoconductive switch comprises a first layer (1), two contact layers (2, 3) arranged on said first layer and connectable to different potentials for applying a voltage thereacross, said first layer being adapted to be conducting upon applying a voltage across said contact layers when exposed to light from an illumination source of an energy high enough for lifting charge carriers from the valence band to the conduction band of the material of said first layer. The illumination source is an excimer lamp, in which unstable electronically excited dimers are formed when a voltage is applied across first and second electrodes (12, 13) separated by a gas or gas mixture. The dimers so formed decompose into two gas atoms while emitting a photon of an energy suitable for lifting charge carriers from the valence band to the conduction band of the material of the first layer.

Abstract: A device having two opposite terminals interconnected by material layers for switching between a current conducting state and a state blocking transport of charge carriers between the terminals upon applying a voltage there across has as the material layers a first layer made of intrinsic diamond and a second layer arranged next to the first layer. The device switches to the conducting state by providing free charge carriers in the second layer for transport through the diamond layer through the voltage and the blocking state by stopping providing the free charge carriers for the transport. The diamond layer is adapted to take a major part of the voltage across the terminals in the blocking state.
