Abstract: A stereolithography method and system for producing three-dimensional plastic objects by forming a plurality of thin layers of partially cured plastic material which are thin cross sections of the desired object. A layer of polymerizable resin is applied to a support surface and the excess is struck off, such as with a doctor blade, to form a smoothed layer. The smoothed layer is subjected to radiation in a predetermined pattern to form the cross-sectional layer into the desired shape. A plurality of layers are subsequently applied, leveled, then cured in the same manner to produce the desired three-dimensional object. Apparatus for measuring the level of the surface of a fluid is also provided. Variations in the level of fluid will be detected and may be used to drive a pump, diaphragm, or plunger in order to maintain the level of the fluid.

Abstract: A superior method and magnetron sputtering cathode apparatus in which some of the flux lines forming the closed-loop magnetic tunnel are made to change their curvature from convex to slightly concave within a region of the tunnel intersecting the sputtering target volume, and over a substantial fraction of the tunnel width. The improved field shape reduces the tendency of the eroded area of the target to become narrower as erosion progresses, and thereby allows more complete consumption of the target.

Abstract: The invention pertains to the method and apparatus of compensating for the axial bearing load forces imposed upon rotary joints conveying a pressurised fluid medium, such as steam, by imposing an axial force on the rotary joint housing (20) proportional to the pressure within the rotary joint (10) by use of a distinctively different pressurised medium than that conveyed by the joint, such as compressed air. An expansible chamber motor (38) capable of imposing an axial force on the rotary joint (10) utilises compressed air whose pressure is controlled by a sensing and regulating system responsive to the pressure within the rotary joint (10).

Abstract: A modular multiplication of integers of large digits can be calculated at high speed although the size of the circuit can be reduced. Furthermore, encryption/decryption for a communication by using cryptograph is performed by using it. In order to achieve this, when the modular multiplication is executed by alternately repeating a partial sum of product calculation and the residue calculation, a portion of the result of the previous calculation larger than the maximum digit of a number which is the modulo of this residue calculation is subjected to the residue calculation in the intermediate stage. Furthermore, the residue is directly obtained from the result of the previous calculation and the partial sum of product calculation is performed in such a manner that an obtained residue is added in place of a portion of the result of the previous calculation larger than the maximum digit of the modulo of this residue calculation. Furthermore, the additions are performed by a plurality of adders in parallel and a carry generated in each adder is added at the next addition performed by each upper adder. This circuit is formed into a systolic array composed by the same processing elements to realize the aforesaid calculation by a pipeline process. <IMAGE>
