Abstract: PURPOSE:To carry out the forging process for multi-crystals of large particle diameter by forging from one end of axial direction by means of pressure from a pressure ram and submitting the pressure of the pressure ram as an internal force on a cover side by means of a carrying section and a column. CONSTITUTION:A pressure ram 29 is disposed corresponding to a carrying section 26 and pressure F is pressurized in the axial direction to a material C to be treated by extending a forging cylinder 27, while inner force of said pressure F is submitted to the material C to be treated from a lower cover 14 side through a forging frame 23. Isotropy hydrostatic molding by a pressure catalyst and mechanical forging by the pressure ram under the high temperature and high pressure in a high pressure chamber can be carried out, and even a multi-crystal ceramics of large particle diameter can be molded and forged accurately by the synergistic effect of hydrostatic pressure and forging. Also, as the forging force can be submitted to the cover side through a column, the insulation of high pressure vessel can be secured effectively and also heat loss can be controlled.

Filed: 1977-12-27
Abstract: PURPOSE: To reduce the production cost of a hydraulic turbine and also the load applied to the side wall of the turbine for opening or closing a guide vane by means of a plurality of servo motors by decreasing the diameter of the ports of the motors.  
     CONSTITUTION: A plurality of servo motors are so disposed that a guide vane is operated in closing direction when hydraulic pressure is applied to the piston rod sides of all the motors and in opening direction when it is applied to the opposite sides to the piston rods. Four serve motors are, for example, disposed tangentially of the circumference of their guide ring all in the same direction. When the guide ring 8 is rorated in the direction of an arrow in the drawing, the guide vane is opened. According to such a structure, since the operating strengths are different at the guide vane at its opening and closing time but the hydraulic resistances of the guide vane are also different in the opening and closing direction, it can design the minimum ports of the servo motors by determining the diamter of the ports of the motors on the basis of the necessary maximum strengths therefor.

The data of a short time determined on the basis of the product of each magnitude of X size and Y size in the certain beam current density of a certain resist are stored in a shot-time data memory 3. Since corresponding pattern shot-time data are called from the shot-time data memory 3 by the size data H, W of the patterns, a shot rank need not be stored in the drawing data memory, in which the size data of the patterns, and the positional data of the patterns are stored, as seen in conventional devices.
