Granted: 1996-10-16
Abstract: Desferrioxamine B or a partially O-acylated derivative thereof is selectively acylated at the nitrogen atom of the amino group by treating a desferrioxamine B derivative in which the amino nitrogen and the hydroxyl oxygen carry an organic silyl group and at least one of the hydroxamic acid groups with an organic acylating agent and then cleaving the silyl groups present. The N- and O-silylated starting materials can be prepared by reaction of a suitable desferrioxamine B derivative containing at least one hydroxyl group and the amino group in unbound form with an organic silicon halide, preferably in situ.

Abstract: PURPOSE:To execute a hardening operation in a short time by adopting an electron-beam hardening resin (EB-curing) silver paste. CONSTITUTION:A silver foil is pasted on one face of a flexible resin insulating film 1; it is patterned to be a desired pattern; and a conductive passage 3 is formed. Then, an EB-curing silver paste 3 is applied to the conductive passage 2 by a screenprinting operation or the like. In addition, a semiconductor element 4 is die-bonded to the paste 3. In addition, a metal sheet 7 of aluminum is brought into contact with the rear side; the paste 3 is irradiated with an electron beam 6 from the side of the semiconductor element 4; and the paste 3 is hardened. When the paste 3 is irradiated with the electron beam, it starts to harden. At this time, the electron beam heats the sheet 7. The heat is applied also to the paste 3 from the side of the insulating film 1; and a stress strain by which the paste 3 is shrunk in its central direction when it is hardened rapidly is annealed and relaxed.

Patent JP-H0447576-B2 (JP)
IPC: A61F2/06
Filed: 1983-12-08
Abstract: A vascular graft is used to supply blood to one or more coronary artery branches. The vascular graft has an elongated U-shaped tubular body providing a continuous passage for carrying blood from a high pressure blood supply to a blood receiver. One or more openings in the body allow blood to flow into the coronary artery branches. The flow and pressure of the blood in the passage is controlled by a restriction providing a Venturi passage located remote from the inlet end of the tubular body. The restriction is reinforced with an annular sleeve to maintain a desired cross sectional area and length of the Venturi passage. The pressure differential between the blood supply and blood receiver maintains continuous and adequate blood flow at a desired pressure in the body passage and provides a continual supply of blood for the coronary artery branches.

Abstract: The illustrated embodiment is an apparatus for detecting the passage of a coin down a coin passageway 14 of oblong cross-section where the width of the passageway is so great that the smallest coin can pass a single sensor in the passageway without activating the sensor. The apparatus comprises a light source 25 and a light detector 26 located in one wall of the passageway, spaced from one another across the width of the passageway and from the sides of the passageway. A prism 29 of transparent material is located in the wall of the passageway opposite the light source and detector and has two 45 DEG  reflecting surfaces 32 and 33. The first reflecting surface 32 reflects a beam of light from the source 25 towards the second reflecting surface 33, the second reflecting surface 33 reflecting the light toward the sensor 26. Thus the beam of light from the source 25 to the sensor 26 crosses the passageway 14 at two positions spaced from one another across the passageway. Even the smallest coin passing down the passageway breaks the beam at one of the crossing positions.

The thin sections (32a) for example can be a legend, or alternatively the thick sections (38) can be the legend while the thin sections (32a) provide a suitable background.The colour changes employed by the invention can be accomplished by such phenomena as stress whitening inherent in various plastic materials. Alternatively, the color changes can be accomplished by mechanisms such as the use of encapsulated staining or coloring agents incorporated in a suitable matrix.

Abstract: Letter-box television signals of 16:9 image format compatible with 4:3 receivers may contain, in the two edge strips above and below the active image, additional information needed by a 16:9 receiver in order to reproduce an image with a resolution close to that of the source signal. This additional information may be modulated on the colour carrier and therefore become unusable when recorded on a video recorder (approx. 600 kHz chrominance bandwidth). If the additional information is recorded in the edge strip lines, e.g. in S-VHS video recorders in combination with corresponding switchovers via the luminance channel, the entire bandwidth (about 5 MHz) of the additional information is retained.
