    摘要： The object of the present invention is to provide a die-cushion apparatus of a press machine capable of performing a preliminary acceleration imparted to a die-cushion pad following the lowering of a slide with an exact timing and high precision and being improved so as to eliminate a pressure deviation between an actual pressure in a hydraulic cylinder and a preliminarily set aimed value at a portion near a lower dead point of the slide stroke. The die-cushion apparatus is provided with a pneumatic cylinder (6), a servo valve (40) for discharge pressure control and a hydraulic cylinder (7) to which a pressurized oil is made up by suction and constructed such that the make-up of the pressurized oil to the hydraulic cylinder (7) at the preliminary acceleration is performed by a pressurized oil makeup circuit (16) provided with a servo valve (22) controlled by a control unit body (14), and a control signal from a pressure control body (27) controlling the discharge pressure control servo valve (40) is corrected in response to the slide lowering speed and the press operation speed.

    摘要： A method of an unmanned vehicle comprises the steps of placing a certain number of ground marks each of which comprises a plurality of line segments on a passage of the vehicle measuring amount of movement of the vehicle between the adjacent line segments when the vehicle moves across each of the ground marks, and obtaining a relative positional relation between the ground mark and the vehicle with reference to the amount of movement thereof whereby movement of the vehicle is properly guided in accordance with the thus obtained positional relation. In the case of a navigational guiding method typically employed in aircraft or ship, an estimated position of the vehicle is corrected with reference to the aforesaid relative positional relation.
