Patent SE-512136-C2 (SE)
Inventor: BAN TAKASHI
IPC: B60H1/08
Filed: 1997-06-16
Abstract: A viscous fluid type supplementary heat generator having a housing assembly defining a fluid containing chamber including a hermetically sealed heat generating chamber in which a viscous fluid is filled to generate heat when the viscous fluid is subjected to shearing action applied by the rotation of a rotor element rotatably arranged in the heat generating chamber. The fluid containing chamber has a predetermined substantial volume with respect to which the volume of the viscous fluid filled in the fluid containing chamber is set at a value between 50% through 70%, i.e., the filling rate of the viscous fluid relative to the substantial volume of the fluid containing chamber of the viscous fluid type heat generator is determined to be a value between 0.5 through 0.7. The determination of the filling rate of the viscous fluid is made so as to protect an oil sealing device sealing the heat generating chamber from being damaged or broken by an excessive pressure prevailing in the heat generating chamber.

Abstract: In a cellular mobile radio system, co-channel radio base stations are provided with a time reference signal being a synchronizing signal or a time reference from another co-channel radio base station. Each co-channel radio base station is also provided with a radio base station specific time offset differing between the co-channel radio base stations by at least a predetermined value which prevents known sequences in desired signals and known sequences in interfering signals from overlapping in a disturbing way at reception. In each co-channel radio base station, the time reference signal and the radio base station specific offset are used for the timing of sending bursts downlink from the co-channel radio base stations towards mobile radio stations. Each radio base station has functions receiving the time reference signal, storing the time offset and using the time reference signal and the time offset for the timing of the burst termination on the downlink.

Abstract: The invention relates to a micro reactor arrangement, particularly for a micro relay. It comprises a substrate (1) with two thermomechanical micro actuators (3, 4). In response to thermal stimulation, the first micro actuator (3) performs a movement in parallel with the substrate surface (2), while the second micro actuator moves in a direction orthogonal on the substrate surface (2). Both thermomechanical micro actuators are so disposed relative to each other that the first micro actuator (3), in the extended state, reaches under the second micro actuator (4). With these provisions, the first micro actuator (3) can be maintained in this position without supply of power when the second micro actuator (4) is de-energized. With the present micro actuator arrangement, one can achieve the advantages of a high activation force and long positioning travels of thermomechanical micro actuators for micro relays, without the necessity to supply energy for maintaining the individual switching states.
