摘要:
A flexible display apparatus comprises a main body with a casing and a slot, a flexible portion, and a supporting portion. The flexible display portion is received in the casing, and is capable of rolling out from the main body from the slot. The supporting portion is surrounding the main body and capable of unfolding with respect to the main body. While the flexible display portion is rolled out of the casing and being straightened, the supporting portion is straightened under the flexible display portion for supporting the flexible display portion.
摘要:
Signal display element for the display of more than two informations by electromagnetically excited magnetic tilting plates, wherein at least two tilting plates in stable condition are arranged and supported in bearings on a baseplate for covering the surfaces of the baseplate carrying the information, the single tilting plates are supported in bearings preferably on two places and displaced in relation to each other, the distance between the common geometric axis of revolution of the tilting plates and the baseplate equals to, or is larger than the half of the total thickness of the tilting plates bearing up against one another.
摘要:
A signal display element for the display of more than two informations by electromagnetically excited tilting plates supported in bearings on a baseplate (1) and containing magnetic parts and adapted to be rotated about an axis of rotation (3), wherein the magnetic axes of the parts of the tilting plates containing the magnets (5) run normal to the plane of the tilting plate, bipolarly excitable field coils are coupled to the tilting plate (4) for controlling the rotation thereof. Parts of the tilting plates (4) containing the magnets (5) are thicker than the non-magnetic parts and the distance between the outer surfaces of the two extreme tilting plates, when the tilting plates (4) are laid on each other on one side of the axis of rotation (3), is equal to the total thickness of the tilting plates, representing the sum of the total thickness of the non-magnetic parts of the tilting plates (4), the number of which is less by one, than the number of all the tilting plates, and the thickness of a magnet (5) of maximal thickness.
