1. A conveyor device, characterized in that said conveyor device comprises a conveyor belt, including a plurality of links slidable on guide means, said conveyor belt being driven by a timing belt through engagement means provided on each of said links and operable to engage the teeth of the timing belt.
2. A conveyor device, according to claim 1, characterized in that said timing belt defines an operating trajectory comprising at least a top flat portion and at least a downward directed loop at a middle position of said top flat portion.
3. A conveyor device, according to claim 1, characterized in that each link comprises a supporting body for a first pair of sliding bearings, of horizontal axis, and a second pair of side guiding bearings, having a vertical axis.
4. A conveyor device, according to claim 1, characterized in that each said link is coupled to adjoining links by pivot pins and rolling bush elements.
5. A conveyor device, according to claim 1, characterized in that each link is provided, at a bottom thereof, with a plurality of teeth having a configuration and a depth size corresponding to a configuration and a size of the teeth of the timing belt, thereby providing said engagement means for engaging said teeth of the timing belt.
6. A conveyor device, according to claim 1, characterized in that said timing belt comprises a metal core covered by reinforced plastic materials.
7. A conveyor device, according to claim 1, characterized in that said teeth of said timing belt are outward directed.
8. A conveyor device, according to claim 1, characterized in that said timing belt slides on said frame, by defining at least a top flat trajectory, as guided by guide rollers, and being engaged by two end pulleys, arranged at respective end portions of said trajectory.
9. A conveyor device, according to claim 8, characterized in that, at a middle region of said top flat trajectory, is provided a toothed pulley arranged at a bottom between a pair of flat pulleys which cooperate with said toothed pulley to cause said timing belt to form a downward directed loop.
10. A conveyor device, according to claim 9, characterized in that said toothed pulley is driven by motor means, comprising either a step motor, a DC motor, or a brushless motor.
11. A conveyor device, according to claim 1, characterized in that a number of said links forming said conveyor belt can be changed depending on a desired length of said conveyor belt, said conveyor belt sliding along a substantially oval guide peripherically arranged of said frame, said guide comprising two rectilinear portions, i.e. a top and a bottom rectilinear portions, coupled by two semicircular portions.
12. A conveyor device, according to claim 11, characterized in that said guide provides a track operating to engage the guide bearings of the links of said conveyor belt, to allow said engagement means, constituted by said teeth of said links, to engage the teeth of said timing belt at least along a top rectilinear portion thereof.
13. A conveyor device, according to claim 1, characterized in that said links are provided with supporting elements for supporting an article to be conveyed.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of driving a liquid crystal display by frame rate control (FRC), the method comprising:
receiving a raw data having a gray from an external graphic source;
converting the raw data having a gray such that the gray of the converted data for the raw data having the gray equal to any one of a predetermined number of lowermost grays is equal to a predetermined gray, and the gray of the converted data for the raw data having the gray other than the predetermined number of lowermost grays is equal to the gray of the raw data subtracted by the predetermined number; and
performing FRC on the converted data.
2.-4. (canceled)
5. A method of driving a liquid crystal display by frame rate control (FRC), the method comprising:
receiving an input data having a first gray from an external graphic source;
converting the input data to have bit number larger than the input data; and
performing FRC on the converted data.
6.-22. (canceled)
23. A liquid crystal display comprising:
a liquid crystal panel assembly including a plurality of pixels arranged in a matrix;
a signal controller converting input data into image data having bit number larger than the input data and performing frame rate control (FRC) on the converted data; and
a data driver for applying data voltages to the respective pixels of the liquid crystal panel assembly in accordance with the converted data.
