摘要： An object discharge mechanism of an object picking device for discharging a bottommost object from a stack of objects includes a bottom platform on which the bottommost object of the stack of objects rests. The platform has a longitudinal slot running along an object discharge direction. The upper portion of a belt, stretched between two vertically mounted pulleys, runs through the longitudinal slot parallel to the upper surface of the bottom platform. Discharge projections are mounted periodically on an outer surface of the belt. The discharge projections push objects across the bottom platform in the object discharge direction when the belt is rotated. The object discharge mechanism also includes a lifting member for lifting all objects above the bottommost object in the stack of objects. The lifting member reduces the frictional force created by the weight of the stack of objects on the bottommost object during discharge of the bottommost object. A controller controls the speed at which the discharge projections travel during the discharge process. Specifically, the speed at which the discharge projections contact the objects to be discharged is dependent on the fragility of the object to be discharged such that the discharge projection moves slowly when contacting objects that are fragile and moves at a maximum speed when contacting objects that are not easy to break.

摘要： In current driving circuit a desired value of a driving current is promptly written in a load of each pixel despite load variations that may occur in each pixel. A constant current source circuit delivers a driving current Idata to a load. An output voltage difference amplifier circuit detects a voltage change produced at a load driving end within a preset time period, and delivers a current or a voltage corresponding to the voltage change during a time period different from the preset time period. The output voltage difference amplifier circuit temporally repeats detection of the voltage change and delivery of the current or the voltage to the load.

摘要： To equalize the intensity of light emitted by display elements on a display device, a plurality of current-drive circuits are connected in cascade through two terminals of each of the current-drive circuits, each comprising a reference current generation section including a reference resistor and a plurality of current drive sections. Reference current sunk by an external reference current source causes a voltage drop across the reference resistor, and the voltage drop is applied across a current adjustment resistor In response to an image signal, the current-drive circuit outputs current, determined by multiplying each of a plurality of internal reference currents by an optional factor and summing the resulting currents to the display elements. Since the magnitude of the internal reference current flowing inside the current-drive circuit can be varied by varying the value of the current adjustment resistor, gamma correction can be applied to drive current with high accuracy.
