Abstract: Abstract of the Disclosure:     For each pel signal capable of taking each of a plurality of levels with a first probability dependent on a reference signal, binary prediction error codes are produced to represent one of serial numbers assigned to the first probabilties arranged in a monotonously decreasing order that is coincident with the actually taken level.  Mode codes are allotted to the respective prediction error codes with each mode cods made to represent a second probability that the prediction error code allotted therewith is binary zero.          The prediction error codes for a sequence of pel signals are grouped according to the mode codes allotted thereto and then compression encoded.  Preferably, the code codes are produced in consideration of the prediction error code or codes of more significant binary bit.  A compassion encoded signal is expansion decoded by alternatingly reproducing the mode codes and the prediction error codes.  Reproductions of the prediction error codes provide reproduced pel signals.  When the pel signal is variable among a great number of levels, the pel signal is preferably represented by a combinattion of one each of a plurality of partial pel signals, each representative of a smaller number of levels.

Abstract: ABSTRACT OF THE DISCLOSURE          In a new method of manufacturing eddy-current probes, particularly such probes for the scanning of a test surface generated by a non-flat profile, a thin, flexible support layer is laid against the test surface so that it conforms exactly thereto.  One or more test coils have a sector thereof laid against the back face of the support layer so that the coil sector also conforms to the same profile in the plane of the coil and the profile.  A plurality of separate ferrite core elements are now laid inside the loop of the coil, or the loops of the coils, and pressed against the coil so as to form a core that also conforms to the profile to be scanned. The remainder of the coil (or coils) is pressed against the backs of the ferrite elements and the assembly is encapsulated to make it rigid enough for mounting in a test apparatus for scanning over the surface to be tested.  The front face of the support layer is the "active" surface of the probe and conforms precisely with the profile, since it was generated thereby.  The invention includes the probes made by the method.

Abstract: PHN 9922                                 11.11.1981 ABSTRACT. Method of manufacturing a semiconductor device.     A method of manufacturing an integrated cir-cuit having at least an insulated gate field effect transistor (IGFET). Provided on the silicon surface (2) are successively a gate oxide layer (15) and a doped sili-con layer (16) which are patterned by etching by means of a silicon nitride-containing mask (17) which comprises the gate electrode(s) (16A, B) and interconnections (16C). Nitrogen ions are implanted in the surface parts not under-lying the mask (17). By thermal oxidation only the edges of the silicon pattern (16) are oxidized. By ion implanta-tion the source and drain zones (23, 24, 27, 28) are formed, the gate electrodes serving as an implantation mask. If desired, the threshold voltage may then be adjusted by ion implantation in the channel region via the gate electrode. The invention is of particular importance for the manu-facture of complementary IGFET pairs in which a transistor is provided in a bowl-shaped zone (11) which is bounded by a p-n junction (14) terminating at the surface between a boron-doped p-type (13) and an adjoining phosphorus-doped n-type channel stopper zone (7).

Abstract: "CONSTANT PRESSURE PUMP"          ABSTRACT OF THE DISCLOSURE        An improved pump is provided for pumping non-lubricating fluids at extremely high pressure while reduc-ing galling and wear on components such as pistons and cy-linders.  The reduction in component wear and galling is achieved by modifying the piston-cylinder combination to provide a pressure area and a centering area that is axial-ly displaced from the pressure area of the piston-cylinder combination.  The pressure area of the piston-cylinder com-bination is modified by reducing the diameter of the pis-ton or increasing the inside diameter of the cylinder or both to provide a .1 percent to 2.5 percent increase in clearance at the pressure end of the piston-cylinder com-bination than is provided at a centering area.  The advan-tages of the invention are further enchanced by employing a release area disposed intermediate the pressure area and the centering area of the piston-cylinder combination.          The pressure end of the piston-cylinder combination in con-junction with a release area further augments the advan-tages of the improved high pressure pump and provides a fluid relief in the event of seal failure so that a pumped non-lubricating fluid is not contaminated with a piston lubricating fluid.  The combination of the pressure end of the piston-cylinder combination in conjunction with the release area allows the pressure end of the piston to oper-ate in a virtually dry condition except for the fluid be-ing pumped by the seal on the end of the piston.  The fur-ther combination of the release area with the centering area of the piston-cylinder combination operates to reduce galling and increase efficiency and component life of high pressure pumps.
