  • Patent number: 8548693
    Abstract: A control device for a work machine on a construction vehicle is provided so that a bucket cylinder is stopped at a target position, with high accuracy achieved in a bucket cylinder length, and with chock held down to a low level. A bucket cylinder length detection section refereces a cylinder length detection table on the basis of a boom angle and a bell crank angle, thereby detecting a bucket cylinder length. A bucket attitude control section controls the bucket cylinder length so that a target position will be reached. Feedback control is performed until a set value which is set short of a target value is reached. After the bucket cylinder length reaches the set value, open loop control is performed until the target value is reached.

  • Patent number: 7218150
    Abstract: An output driving circuit has a first and second differential output nodes connected to a first and second external output terminals, respectively. A capacitance connection circuit is connected between the first and second differential output nodes. The capacitance connection circuit connects a capacitance between the first and second differential output nodes. The capacitance connection circuit then adjusts the value of the capacitance in accordance with a control signal.

  • Patent number: 6467941
    Abstract: A vehicle discharge lighting unit can include a bulb mounting slot provided in a resin base. The mounting slot has a channel diameter that fits with an outer bulb of a lamp. A flange can be provided for mounting the resin base to a reflector. A burner band mounting section of the base can extend towards the lamp along a discharge chamber direction and project within the reflector. The driver case can also be separated into a front case and a rear case. The resin base and the driver case can therefore be most appropriately shaped while also having improved dielectric strength. When either of the base or the driver case is defective, only the part that is defective needs to be replaced.
