Patent EP-0370950-A1 (EP)
Inventor: KRAHENBUHL ANDRE
IPC: B23H7/26
Filed: 1989-11-09
Abstract: This machine for spark-erosion in a liquid medium has a wire electrode. A spindle (1) activated by an electric motor (15) is placed in a leaktight casing (17). A hydraulic-clamping chuck (3) enables the workpiece to be fastened to the spindle and rotated against the electrode. The current passes from the casing to the spindle via conductive rings (11, 12), and then to the chuck. The roller bearings supporting the shaft of the spindle are insulated by insulating rings (8). The insulating rings prevent the passage of the current to the balls and the electrical discharge wear of the latter. The machine makes it possible to shape workpieces by electrical discharge machining in a liquid medium and thus to obtain irregular surfaces, for example spherical surfaces, by combining the rotary movement of the workpiece with a translational movement of the wire electrode relative to the workpiece. <IMAGE>

Abstract: Chaque ligne dans un bloc de données vidéo est organisée en morceaux continus de pixels blancs, et les morceaux ayant des longueurs inférieures à un seuil donné, sont transformées en pixels noirs. Les données sont ensuite organisées en morceaux de pixels noirs, et la position de départ du morceau de pixel le plus long est notée pour chaque ligne horizontale. L'angle d'obliquité est calculé à partir de la distance de décalage entre les positions de départ des morceaux de pixels noirs notées des lignes successives. L'angle de décalage est calculé à partir de la moyenne d'un ensemble de distance de décalage, l'ensemble étant assez grand pour réduire au minimum l'écart standard RMS de distances de décalage inférieures à une valeur prédéterminée. L'ensemble des morceaux successifs noirs correspond à une configuration en escalier à chaque fois que l'angle d'obliquité n'est pas nul.

Abstract: A C-terminal modification of proteins by chemically reactive or recognition-specific modifiers is achieved in a straightforward and unambiguous manner by enzymatic reaction of the protein with an amino acid or an amino acid derivative with coupled-on modifier or modifiers but with a free  alpha -amino group. The C-terminal modification by amide formation takes place using protease, especially carboxypeptidase Y. It is particularly expedient to use a trifunctional L-amino acid derivative with a modifier or modifiers coupled on via the third functionality and/or carboxyl functionality, e.g.  epsilon -N-modified L-lysinamide. Modifiers which are particularly used for protease linkage to the amino acid or to the amino acid derivative are biotin, maleimidoalkanoic acid, pyridyl disulphide, phenyl azide, dansyl chloride, dabsyl chloride, (4-iodoacetyl)aminobenzoate, 4-azidosalicylic acid and 2-(p-azidosalicylamido)ethyl 1,3'-dithiopropionate.

Abstract: A method of depositing high quality diamond films and a light emitting device employing such films are described. The deposition is carried out in a reaction chamber. After disposing a substrate to be coated in the chamber, a carbon compound gas including a C-OH bond is introduced together with hydrogen. Then, deposition of diamond takes place in a magnetic field by inputting microwave energy. The present invention is particularly characterized in that the volume ratio of the carbon compound gas to hydrogen introduced into the reaction chamber is 0.4 to 2, the pressure in the reaction chamber is 0.01 to 3 Torr, the temperature of the substrate is kept between 200 to 1000 °C during deposition, and the input microwave energy is no lower than 2 KW. By virtue of this method, uniform and high quality diamond films can be formed.

Abstract: A radiotherapic system which can conduct streamlined and labor-saving operations ranging from a stage in which a patient is diagnozed, the position, size and shape of the affected part, etc, are identified and a remedial plan such as radiation field is determined, to positioning of the radiation field for the patient and the execution of radiation. In the present invention, tomographic pictures are taken by use of X-ray CT, three-dimensional coordinates of the center position of an interested region subjected to radiotherapy and a fluoroscopic image of the interested region equivalent to a fluoroscopic image obtained by an X-ray simulator are obtained by the calculation of image data of the tomogram by a computer. The reference position of the therapy is marked on the patient on the basis of the three-dimensional coordinates of the center position of the interested region by use of a positioning apparatus, and the radiation collimator of the therapeutic apparatus is controlled on the basis of the calculated fluoroscopic image of the interested region by a therapeutic apparatus controller.

Abstract: A system for the nonvolatile storage of data, such as a postage meter system, employs a microcomputer (104) coupled to two nonvolatile memories (106, 108). The first MNOS nonvolatile memory (106) requires data to be applied for more than a predetermined time for data to be written into a said nonvolatile memory (106) while the second EEPROM nonvolatile memory (108) is such that data applied for less than the predetermined time is sufficient for data to be written into the second nonvolatile memory (108). Each nonvolatile memory (106, 108) has address and data lines, which are coupled to microcomputer ports such that the MNOS memory data lines are always at a high value whenever the EEPROM memory (108) is addressed for the purpose of writing or reading. In the postage meter system transactional accounting data records are stored in the nonvolatile memory (106, 108). The most current record can be rapidly identified. A program store causes the microcomputer, when an error is detected in at least one of the nonvolatile memory records, to rewrite data into both the full record and the abbreviated data record stored in the nonvolatile memory (106, 108).

Abstract: The digital counting circuit can be used for evaluating a digital input signal (S), which can have an arbitrary duty cycle, using a conventional digital counter (Z). To obtain a reliable evaluation, the input signal (S) is divided via a frequency divider (FT) so that the output signal (S/2) of the frequency divider (FT) has a duty cycle of 1:1. To double the counting range compared with the counting range of the counter (Z) used, the output signal (S/2) is looped past the counter (Z) and used as "quasi" output signal (N + 1) in addition to the output signals (N) of the counter (Z). <IMAGE>

Abstract: In a continuous hot strip rolling system in which bars are joined between a roughing train (1) and a finishing train (2) for continuous rolling, the roughing train (1) includes two two-high twin-roll arranged stands (3,4) each having two pairs of work rolls. The four two-high mills provided by the two twin-roll arranged stands (3,4) including four pairs of work rolls are disposed close to each other so as to provide a tandem rolling in which a material to be rolled is rolled simultaneously by the two adjacent mills. A slab (22) having a thickness of 200 to 240 mm is rolled by the two twin-roll arranged stands (3,4) to obtain a bar of about 80 mm. A width press (9) is provided near the entrance of the No. 1 stand. A descaling device (16,17) is provided at the entrance of each of the two stands (3,4). The descaling device (16,17) has a nozzle (30) which is movable in the direction transverse to the direction of travel of the material to be rolled. A non-driven roll edger (18,19) is provided at the exit of each of the two stands (3,4). Thus, generation of camber in the roughing rolling process can be reduced, and stable joining continuous rolling can be conducted. Furthermore, the overall length of the system can be reduced, and reduction in the bar temperature, which occurs until the bar reaches the joining position, can be lessened. Rational bar joining can be conducted.
