Title: Method and equipment for manufacture of hot-drawn wide strip
Inventor: MIRAN KOSANOBUICHI
IPC: C21D9/00
Filed: 1995-05-11
Abstract: PURPOSE: To use second class scraps without any inconvenience at a hot-rolled wide strip production equipment by sufficiently decreasing the surface temperature of a slab between a continuous casting equipment and an equalizing furnace so that a conversion of a structure from austenite to ferrite/perlite takes place. CONSTITUTION: A concentrated cooling line 1 is located in front of the entrance of a roller open-hearth furnace. The cooling line 1 is a water-cooling line equipped with multiple beam type coolers 4 whose operation can be switched on and off. At the cooling line 1, the temperature of the surface 2 of thin slabs 3 having a thickness of between 40 and 70 mm is decreased to a temperature of a transformation point Ar3 or below over a sufficient depth of the slab. Thus a structural transformation accompanied by a new arrangement of austenite grain boundaries is enforcedly formed after a reheating in the roller open-hearth furnace.  In this case, in order to assure a sufficient structure transformation as deep as at least 2 mm, a temperature is so selected that it is not below 600 deg.C and an average surface temperature of the slab becomes a threshold value of the austenite of every material or higher.

Title: Axial piston pump
Inventor: KOSAKA MASATO
IPC: F04B1/24
Filed: 1979-09-07
Abstract: PURPOSE: To improve the self-sucking performance of a pump by tilting a cylinder port to the direction of circumference of the rotation of a cylinder block and by opening the port in such a manner that the center of the opening of the port on the side of a valve plate is in line with the center of the bore of a cylinder.  
     CONSTITUTION: A port 11 is titled to the back in relation to the rotational direction of a cylinder block 5, and the angle of tilt is set so as to accord with the tilt angle of the resultant velocity vector of the circumferential velocity of the rotation of the cylinder block 5 and the moving velocity of a piston 4. In his way, the flow-in of the working oil in the course of suction stroke of the piston 4 is made smooth, the suction resistance is reduced, and thereby the self-sucking capability can be increased. On the other hand, since the center O 1  of the opening of the port 11 is made to accord with the center O 2  of the bore of a cylinder 10, the discharge counterforces generated between a valve plate 6 and the cylinder block 5 in the course of discharge stroke of te pump and repulsive to each other do not become a couple of forces to cause the rotation in any directions in relation to the axial line of the cylinder. Thus, vibrations of the cylinder block 5 are held down and the stability of the operation of the pump is obtained.
