Abstract: PURPOSE: Provided is a bevel gear truck in a roller board which combines several bevel gears properly to apply relative movement of the bevel gear to the truck so that it gives the roller board freedom to change direction. CONSTITUTION: The bevel gear truck in the roller board comprises the parts of: a fixing axis(15) for the bevel gear and a center bevel gear(14) which are fixed at a base plate(18) without relative rotation movement; a left and a right direction-adjusting bevel gear(13,16) which are placed at left and right side of the center bevel gear; a left and a right direction-adjusting lever(11,19) which are fixed at one edge of the left and the right direction-adjusting bevel gear by a nut(12) and combined with a roller wheel(10) to be contacted to the ground and rotated; and a direction-adjusting box(17) which is rotated entirely with the left and the right direction-adjusting gear and the left and the right direction-adjusting lever on a basis of direction-adjusting center(1A-1A').

Abstract: PURPOSE: An input system accompanying coordinates detection through induced magnetism is provided to input coordinates faster and more stably. CONSTITUTION: Two long wires(L1,L2) are equipped with an insulation ground device, and are corresponded to an X and a Y-axis of the input system. A control circuit detects a size of the magnetism. A zero device makes geomagnetism and overall magnetic field interfering source to zero. Another two long wires(L3,L4) are equipped with other insulation ground device, and are placed to an opposite side of the X/Y axes in order to check/reinforce accuracy.

Abstract: PURPOSE: A method for driving a plasma display panel and an apparatus for the same are provided to adaptively vary the level of the driving voltage in response to peripheral temperature of the devices. CONSTITUTION: A method for driving a plasma display panel is characterized in that it adaptively controls the level of the driving voltage in response to the peripheral temperature of the plasma display panel. The method drives the plasma display panel with dividing the period into a reset period, an address period and a sustain period.
