  • Patent number: 5391843
    Abstract: An object of the present invention is to accurately measure a carrying weight of a vehicle on the basis of a force applied to suspension cylinders and allow an operator to accurately recognize the weight. A first force applied to a front wheel suspension cylinder of a vehicle carrying a load can be obtained on the basis of detection values of pressure sensors (2a, 3a, 2b, 3b), and a second force applied to a rear wheel suspension cylinder can be obtained on the basis of detection values of pressure sensors (2c, 3c, 2d, 3d). An inclination O of the vehicle in the longitudinal direction is detected by an inclinometer (8), and the first and the second force are corrected in accordance with this inclination O. Further, the first and the second force are corrected in accordance with the magnitudes of the first and the second force to thereby obtain the weights of the vehicles on the front wheel side and the rear wheel side.

  • Patent number: 5389959
    Abstract: There is disclosed a thermal printer system having a multiple channel laser print head which focuses closely spaced spots of laser light energy onto a dye donor element which moves at constant velocity relatively past the print head. These laser light spots respectively print multiple lines of an image a swath at a time by heat transfer of pixels or subpixels of dye from the dye donor element to a receiver element. A light source (such as an arc lamp) applies to the dye donor element one or more precisely positioned spots of light energy which elevate the temperature of the dye donor element substantially uniformly within a zone coincidently with and closely surrounding the laser light spots. The shape, the position and the power absorbed within the zone from the light source are carefully controlled. Thus the temperature within this zone is held to a substantially uniform value slightly below the vaporization temperature of the dye to be transferred from the dye donor element.

  • Patent number: 5384583
    Abstract: An ink jet printing device has a drop generator for producing continuous streams of ink drops from at least one orifice and further has stimulation control electronics for maintaining desired stimulation conditions in response to a feedback from the drop generator. First and second feedback transducers measure the stimulation amplitude in the drop generator and generate feedback output signals in response to the stimulation. The feedback output signals are approximately equal in magnitude and opposite in sign to each other when the stimulation amplitude in the drop generator is a desired stimulation mode. An amplifier, whose inputs are the feedback output signals, provides an amplifier output signal to the stimulation control electronics which is the difference between the two feedback output signals.

  • Patent number: 5384436
    Abstract: A mobile apparatus and method for weighing bales on an electronic scale in a field. Fixedly supported on the rear end of a mobile crop baler are two load cells from which is pivotably suspended the inboard end of a bale-receiving-structure. The outboard end of the bale-receiving-structure is adjustably supported by a tether from at least one other load cell fixed to a rearwardly extended portion of the baler which allows the outboard end to swing upwardly as the underside of the bale-receiving-structure encounters berms in the field thereby preventing damage to the electronic scale components. The weight of each bale produced by the baler is digitally readout in the baler cabin where, by comparison to a predetermined weight, real time adjustments are automatically or manually made to adjust bale weight to the predetermined weight, thereby achieving greater weighing accuracy and enhanced overall output from the field. The scale may be used on original equipment balers or made to retrofit existing balers.
