Abstract: The invention relates to the manufacture of plastic boats in a sandwich construction using so-called square-cut cellular-plastic material as spacing material. For the purpose of ensuring that the gaps of the cellular-plastic material (6) are completely filled, a curable filler substance (4) is applied to the inner surface of the outer laminate (3) and a spacer member (mesh 8) and a sealing layer (plastics 9) are placed over the cellular-plastic material (6). A suction element (10, 11) connected to a vacuum source of about 0.9 atmospheres is then activated, such that the filler substance is positively drawn up into the gaps (5) in the cellular-plastic material (6). This takes place so quickly that it is possible to apply filler immediately and to apply the inner laminate (7) wet-in-wet.

Abstract: An ink-jet recording head, in which at least two piezoelectric substrates (1, 20, 30) are opposite each other in polarization direction, grooves (3, 21; 4, 31) are formed across the interface of the two substrates at a predetermined pitch so as to form cavities, at one end of which are opened to the atmosphere and have orifices (50, 51) adapted for squirting ink drops. Those cavities have electrodes (17, 18, 24, 34) formed on their inner surfaces. When a voltage of one polarity is applied to the electrode for the cavity from which ink drops should be generated whereas a voltage of the other polarity is applied to the electrodes for the two adjacent cavities, the diaphragms separating the three cavities will deform in a shear mode towards the cavity from which ink drops should be generated. As a result, the capacity of the cavity from which ink drops should be generated decreases to have the ink in said cavity squirted outward from the orifice (50, 51).

Abstract: A developing roller (1) used in an electrophotographic developing machine is improved in the efficiency of separation of a developer (300) on its surface. A magnetic working force functioning to separate the developer (300) from a sleeve surface (2) is designed on the basis of a magnetic attraction force which results from a vector composite force consisting of a radial magnetic flux density and a tangential magnetic flux density on the sleeve surface (2) and actually controls the behavior of the developer (300). The magnetic working force acting on a separation zone (A) of weak magnetic flux density is made to act as a magnetic repulsion force functioning to separate the developer (300) from the sleeve surface (2). The magnetic working force acting on a given area inclusive of a spot proximate to a photoconductor in a development zone is made to act as the magnetic repulsion force functioning to separate the developer (300) from the sleeve surface (2).

Abstract: A cardiac discrimination method in which feature values of a heart related signal (e.g., cardiac biopotentials) determined to be non-baseline are compared with feature values of a heart related signal determined to be normal baseline. The feature values are extracted on an event-basis (a periodically), for obtaining feature values of a complex. For each complex, the feature values form a sequence with the value having the largest absolute value for the sequence given special identity as a fiducial point. The normal baseline complexes' characteristic sequence and a non-baseline complex's sequence are aligned according to the fiducial points, and unoccupied positions on the ends of the sequences resulting from the alignment are filled with zeros to create normal baseline and non-baseline vectors. The similarity value and dissimilarity value of the normalized non-baseline vector with respect to the normalized normal baseline vector are determined. The type of tachycardia (VT or non-VT) and consequently the selection of appropriate therapy are determined by the location in a discrimination plane of a discrimination point, the coordinates of which are equal to the similarity and dissimilarity values. In addition, the location of a similarly generated hemodynamic discrimination point can be used to discriminate hemodynamically stable and unstable tachycardias based on the features derived from events in hemodynamic related

Abstract: A process for the manufacture of tetrachloroethylene comprising steps of producing tetrachloroethylene by the reaction of a hydrocarbon having 3 or less carbon atoms, a partially chlorinated hydrocarbon having 3 or less carbon atoms, or a mixture of these, with carbon tetrachloride and chlorine gas in a reaction vessel at 500-700°C, obtaining the gas formed in the reaction at a state wherein the amount of carbon tetrachloride therein is equivalent to or smaller than the amount of the carbon tetrachloride supplied and the chlorine concentration therein is 7-15 mol%, separating and collecting tetrachloroethylene from said gas formed in the reaction by distillation, and recycling all amount of carbon tetrachloride in the gas formed in the reaction and chlorine gas to the reaction vessel for reuse. Recycling of carbon tetrachloride and chlorine gas ensures the conversion of the carbon tetrachloride into tetrachloroethylene in a closed system, prevents production of carbontetra chloride in the manufacturing of tetrachloroethylene, and makes it possible even to convert carbon tetrachloride by-produced in other processes into tetrachloroethylene.
