  • Patent number: 11964604
    Abstract: When a tilt in a right-and-left direction occurs in a cargo bed (9) being raised due to imbalance of excavated materials, the tilt is detected as a roll angle (?R), and it is determined whether the absolute value (|?R|) of the roll angle is not less than an imbalance determination value (?2) (S4). When the absolute value is not less than the imbalance determination value (?2) (Yes in S4) and the roll angle (?R) is positive (the cargo bed (9) is rising to the right) (Yes in S8), an oil supply amount (VL) to a hoist cylinder (11) on the left side is increased, and an oil supply amount (VR) to a hoist cylinder (12) on the right side is decreased (S9). When the roll angle (?R) is negative (the cargo bed (9) is rising to the left) (No in S8), the oil supply amount (VL) on the left side is decreased, and the oil supply amount (VR) on the right side is increased (S10).

  • Patent number: 5870682
    Abstract: Digital data extracted from an FM multiplex broadcasting wave is decoded by an FM multiplex decoder. The decoder FM multiplex data is applied to a CPU. According to a logic of a switch, the CPU selects display of one page or a plurality of pages to read out predetermined data from memory according to the selected result. Display data is produced on the basis of the decoded FM multiplex data and each readout data. The produced display data is provided to a display unit. The display unit selectively displays data of one page or data of a plurality of pages simultaneously on one screen according to the input display data. The data of each page is identified and displayed corresponding to each data using an identifier.

  • Patent number: 5740135
    Abstract: A disc reproducing apparatus which allows an uncomplicated and precise operating control reducing number of parts used and without increasing the size of structure of the apparatus is disclosed. In this disc reproducing apparatus, a first portion, to be detected, forms a disc number detecting mark. The first portion has a width smaller than a width of a second portion, to be detected, which a stop position detecting mark. At the same time, the disc number detecting mark and the stop position detecting mark are provided on a straight line. Thus, the disc number detecting mark and the stop position detecting mark can be detected by one mark sensor with both marks reliably distinguished from each other.
