Title: Hydraulic driving device for construction machine
Inventor: NAGASAWA KIYOTAKA
IPC: E02F9/22
Filed: 1991-02-07
Abstract: PURPOSE:To enable supply of respective required flow rates to a plurality of flow rate control valves 4 regardless of the magnitude of inlet pressures (load pressure) of a plurality of actuators 5 and to correct the total of the required flow rates so that it accords with the maximum discharge flow rate when the total of the required flow rates exceeds the maximum flow rate in a hydraulic circuit for driving a construction machine such as a power shovel. CONSTITUTION:The magnitude of inlet pressures of actuators 5a and 5b is judged by a control device 8 so that an opening area of a flow rate control valve on the larger side becomes maximum, and a pump discharge pressure is calculated by the opening area of the flow rate control valve on the large inlet pressure side and a required flow rate, while the opening area of the flow rate control valve on the smaller inlet pressure side is calculated by the discharge pressure of the pump and the required flow rate. A control command is generated according to the results and when the total of the required flow rates exceeds the maximum flow rate of the pump, correction is made so that the total of the required flow rates becomes the maximum discharge flow rate of the pump.

Title: Cooled mold for pull-up continuous casting of tube body with inner fin
Inventor: FURUTA MASAO
IPC: B22D11/04
Filed: 1992-02-25
Abstract: PURPOSE:To simplify a constitution with eliminating core by cyclically and up and down varying a step part peripherally which an inside surface of sleeve is peripherally recessed at upper part more than at lower part. CONSTITUTION:A molten metal solidified layer becomes very breakable at the boundary 61 of the step part 6, therefore, a pull-up lowest end of the molten metal solidified layer is restricted to the step difference position. Accordingly, as the molten metal solidified layer reaches molten metal surface, its thickness becomes gradually larger, the step part 6, which cyclically and up and down varies peripherally on the sleeve 2 being in contact with melt solidified layer, is formed, at each peripheral position of the molten metal solidified layer, a time to reach differs to cause difference in the thickness. That is, the pattern of step difference at cross section is reflected on the thickness pattern to forma fin on inner surface at the same time as casting. Thus, the constitution of the cooled mold 1 is simplified by the extent of elimination of core.
