Abstract: PURPOSE:To shorten the time of transfer of a transient program from an auxiliary storage device to a main storage device when the transient program is executed, by preliminarily transferring the transient program from a low-speed access medium to a RAM as a high-speed access medium in the auxiliary storage device. CONSTITUTION:In case a transient program P3 is transferred to a main storage device 200 to execute the processing, a central controller 100 designates an address of a magnetic disc to an auxiliary storage device 300, namely, an auxiliary storage control circuit 310 and instructs the circuit 310 to transfer the program P3 to the main storage device 200.

Title: Improvement of propeller for shipping
Inventor: KOKUSON JIYON RICHIYAADO
IPC: B63H3/00
Filed: 1980-08-29
Abstract: A variable-pitch marine propeller comprises helicoidal blades 6 each mounted on a hub 1 to freely pivot about radial axis 25 spaced in front, in the direction of rotation, of the center of pressure of the blade 6 whereby water pressure acting on the blade exerts a torque which tends to turn it about its axis in a direction to bring the surfaces of the blade into line with the flow of water over it. The axis 25 is also spaced behind, with respect to the direction of movement of the propeller through the water, a major portion of the pressure surface of the blade whereby, the resultant of the drag of the water exerts a torque which tends to turn the blade in an opposite direction. The shape and mass distribution of the blades relative to their pivot axes are also such that centrifugal effects tend to move the blades, in the absence of hydrodynamic forces, into a pitch equal to that of the helicoid. In operation each blade adopts a stable equilibrium position in which its pitch is optimally suited to the speed of rotation and the linear axial speed of the propeller.
