Abstract: A joining link, a strut, and first and second expansion levers constitute an expansion and contraction device. At the time of the braking, the proximal end portion of both of the expansion levers are mutually pressed from the opposite sides by first and second pressing members constituting a driving device. The reaction due to the braking is offset by the joining link portion, whereby a large force is not applied to the back plate or the like.

Abstract: A method is disclosed for uniquely determining the position of a mobile earth station in a mobile satellite communication system which employs a non-geostationary satellite with a multi-spot beams. A given point of a preknown position on the earth surface is defined as the center coordinate of a three-dimensional coordinate axis, information on the measured distance and Doppler shift amount between a mobile earth station of an unknown position and a non-geostationary satellite is used to repeat the estimation of the position of the mobile earth station a plurality of times, thereby obtaining the position of the earth station with high accuracy. Furthermore, by observing the estimated positions of the mobile earth station obtained as a plurality of solutions at proper time intervals, comparing with one another the movements of the respective estimated positions occurring with the local time proceeds and selecting the estimated position of the minimum movement, the estimated position of the mobile earth station is uniquely determined relative to its true position.

Abstract: In a time division multiplex (TDM) signal in which a symbol is sent one by one periodically, a unique word in the TDM signal is recognized quickly in a receiving station. A receive station has essentially N number of correlators each having a specific unique word pattern. A unique word pattern in each correlator is obtained by shifting by predetermined symbols cyclically from a reference unique word pattern. Each correlator provides a correlation value between a received TDM signal which includes a unique word and a unique word pattern defined in the correlator. Among outputs of N number of correlation values, which exceed a predetermined threshold value, the correlator which provides the maximum correlation value is selected, and the receive timing of the unique word is determined by the correlator thus selected.
