Abstract: A covering structure including a bottom covering layer, a top covering layer, and a thermoplastic material layer is disclosed. The thermoplastic material layer is laminated between the bottom covering layer and the top covering layer. The thermoplastic material layer includes a first thermoplastic material layer part and a second thermoplastic material layer part that are connected to each other. The first thermoplastic material layer part has a first thickness. The second thermoplastic material layer part has a second thickness. The first thickness is larger than the thickness of the top covering layer. The first thickness is 4˜7 times of the second thickness. The disclosure further discloses an input device using the covering structure and a manufacturing method of the covering structure.

Abstract: A portable input device includes a support board, a plurality of key modules, a second input module, a cover, and at least one control unit. The support board has a first disposing region and a second disposing region. The key modules are located on the first disposing region of the support board. The cover covers the support board and has at least one opening. An accommodating space is defined by the cover and the second disposing region of the support board. The second input module is located in the accommodating space. The control unit is located in the accommodating space and electrically connected to the key modules and the second input module.

Abstract: A one-way bearing, provided with a passive element on its outer periphery and connected with an axle rod with its inner periphery, comprises a collar, a lid and a plurality of braking blocks. The collar has thereon a plurality of spaced notches, and the braking blocks are respectively rotatably received in the notches of the collar. The braking blocks are provided each with a braking portion; when the axle rod rotates in one direction, the axle rod is linked up with the passive element; when the axle rod rotates in a contrary direction, the braking portions have no function, so that the power of the axle rod and the passive element will be interrupted.

Abstract: A roller bearing consists of a hollow cylindrical main body, two annular locating plates, a plurality of rolling bodies and elastic elements. The cylindrical main body is provided with at least three roller grooves equidistantly and equiangularly spaced and disposed around its interior hollow. Each roller groove is configured to have an elastic element seat arranged at its deeper end. The groove wall around the groove opening connected to the interior hollow of the main body extends and forms a reduced neck portion, which makes the groove opening have a width smaller than the diameter of rolling bodies to keep rolling bodies from dropping out of the groove. On the central area of each end surface of the cylindrical main body is an inner annular portion and between end surfaces of the main body and of the inner annular portions are provided with locating grooves.

Abstract: In a telecommunications switching system having a central processor for generating control signals, peripheral units, and a power source terminal, a power control arrangement includes a plurality of power switches for selectively connecting and disconnecting the peripheral units and the power source terminal in order to minimize power consumption. Responsive to peripheral unit control signals, a power control unit, which is included in the arrangement, controls the operation of the power switches so that only those peripheral units designated by a control signal are connected to the power source terminal. After the peripheral units have been operated, the power control arrangement disconnects the operated peripheral units from the power source terminal.
