Title: Processing circuits for operating on digital data words which are elements of a galois field
Inventor: ODAKA KENTARO
IPC: G06F7/00
Filed: 1982-03-23
Granted: 1989-03-30
Abstract: A processing circuit suitable for use in error correction a transmitted or recorded digital signal operates on digita. data words to form products or quotients of the quantities represented by the digital data words. The data words are considered as elements α<sup>i</sup> of a Galois field GF(2<sup>m</sup>) where each element is a power α<sup>i</sup> of an irreducible root a. The data words are supplied into a conversion ROM (1) which in response provides the corresponding exponents i, j as an output. These exponents i, j are additively combined to form a sum (i + j) or difference (i - j), and this is applied to a reverse conversion ROM (3) which then provides, as an output data word, an element α<sup>i+j</sup> or α<sup>i-j</sup> which is the product or quotient, respectively, of the input data words. A provision (10) can be incorporated to compensate for division by a zero element.

Abstract: A blood pump comprises an atrium chamber defined by flexible walls and having an inlet and an outlet, a ventricle chamber defined by flexible walls and having an inlet and an outlet, a passage communicating the outlet of the atrium chamber with the inlet of the ventricle chamber, a first one-way valve in the passage adapted to permit blood flow only from the atrium chamber to the ventricle chamber, and a second one-way valve in the outlet from the ventricle chamber adapted to permit blood to flow through the outlet only out of the ventricle chamber. The chambers are movably supported in a casing having first and second openings, the atrium chamber inlet being fastened to the first opening and the ventricle chamber outlet to the second opening. A drive device cyclically moves the walls of the ventricle chamber to decrease its volume and expel blood from it while simultaneously moving the walls of the atrium chamber such that its volume may increase upon inflow of blood into the inlet to it. The drive device includes a drive ring surrounding and joined to the passage and having a surface engageable with the walls. of the ventricle chamber over a selected area such that the pressure of blood entering the chambers between driven strokes of the drive device controls the output of the blood pump by establishing the magnitude of the return stroke of the drive ring as a function of a pressure force acting over the area of engagement between the drive ring and the walls of the ventricle chamber.

Abstract: A method for detecting a liquid level liquid level is monitored at mutually opposing sides of a liquid containing bottle. For monitoring the liquid level at each side of the bottle, a diffused light beam is irradiated toward the liquid surface from the level below the liquid surface. The light reflected at the liquid surface and the light refracted at the liquid surface are deteted by a photo-receiving camera which is focused at a standard liquid level. An average value of the monitored liquid levels at both sides is taken as a liquid level indicative value. By employing the aforemention method, acurate detection of the liquid level becomes possible even when the liquid level is unstable.

Abstract: An improved welding device with supporting elements for external welding of circular seams in abutting tube sections or curved tube components, a plurality of curved supporting elements forming a complete annular arrangement which is flexibly preloaded and pushes outwards against the inner tube surface in the welding area between tube sections abutting end to end. There is no separate tube-clamping mechanism; on the contrary, there is only a double-acting fluid cylinder which is fitted between two mounting shoes carrying the supporting-element arrangement and performs a double function owing to the fact that the requisite radial force is applied for aligning the tube sections and for the means for expanding and contracting the supporting-element arrangement. A novel outer clamp element assists the very accurate positioning of the device and the spacing of the joint gap.
