Abstract: The present invention can be applied to a cipher processing apparatus, which includes a function F having a configuration of repeating process and inside of the function F, a function f having a configuration of repeating process is included. According to the invention, the cipher processing apparatus is configured by registers 301 through 303 for temporarily holding data, selectors A through C, 311 through 313, and a function f operating circuit 323 for transforming data. An output data from the function f operating circuit 323 is held in the register C 303, and the selector C 313 selects either to repeat the data transformation by the function operating circuit 323 or not. When a cipher processing apparatus includes a function F having a configuration of repeating process and inside of the function F, a function f having a configuration of repeating process is included, the cipher processing apparatus can be embodied efficiently, which enables to reduce the circuit scale and to save electric power.

Abstract: A mounting device (10, 10') for coaxially anchoring a machine element (11, 11') upon a rotary shaft (12, 12'). The device fits between the interior bore (13, 13') of the machine element and the cylindric al surface of the shaft and is effective to position the element at any desired position longitudinally of the shaft and at any angular position circumferentially of the shaft. The device has inner (20, 20') and outer (50, 50') sleeves, the mating surfaces of which are similarly tapered so that relative axial displacement of the sleeves effects expansion and contraction of the interior bore (13, 13') and external surfac e of the combined elements. Rotation of a threaded nut (23, 45') at one end of the device effects the relative axial displacement of the inne r and outer sleeves to afford expansion and contraction of the outer sleeve (50, 50').

Abstract: A shaped charge for generating a large hole in material such as well casing downhole in a wellbore. A shaped charge liner is oriented about a longitudinal axis, and a disk is positioned at the liner apex. When an explosive material is initiated the liner collapses into a perforating jet. The disk alters the jet formation process and changes the shape and location of a bulge within the perforating jet. Consequently, the shape of the perforating jet retains a larger diameter for generating a larger hole in the material to be perforated or for controlling the penetration depth. The disk surfaces can be flat, concave, convex or other shapes, and the disk composition can be varied to accomplish different design criteria.
