Patent EP-0394782-A2 (EP)
Inventor: ROEMER PETER BERNARD
IPC: G01R33/385
Filed: 1990-04-13
Abstract: An etched coil for producing a Z-axis magnetic field gradient responsive to flow of a current I, has a number N of pairs of elongated conductive strips, with each strip of a pair being positioned substantially symmetrically about a central insulative cutline, and insulatively spaced from all other strips, and with a first strip being insulatively severed into first and third strip portions; the strips are connected so that current flows into a first one of said strips and then between each successive pair of the strips until the current flows out of a last one of the strips. There are interconnectors used, in each i-th pair, where 1≦i≦N, to connect a first end of a first strip of that pair to a substantially-symmetrically disposed first end of a second strip of that pair, and also to connect a second end of the second strip of that pair to a substantially-­symmetrically disposed end of the third portion of that pair; these interconnectors are positioned adjacent to one another and, when the strips are rolled into a substantially cylindrical form, will radially overlap in the ϑ direction of the resulting coil, so that a magnetic field due to flow of the current in any one of the first interconnectors will be substantially cancelled by another magnetic field due to flow of the same current in a corresponding one of second interconnectors.

Abstract: Described is a process for the continuous bulk production of high impact vinylaromatic copolymers in which a vinylaromatic monomer, an optional vinyl-cyanide comonomer, a rubber, a part of a diluent solvent and a catalyst are premixed at a tempera­ture below 100°C and fed to an agitated tubular plug-flow reactor which is divided into several stages or zones. The excess mixture is recycled to the premixer and the remaining portion of the diluent solvent is injected in the top of the reactor to prevent the formation of incrustations. In the first zone of the reactor, the temperature and the residence time of the mixture are controlled so as to halve the catalyst lifetime. 
     The polymerization is continued in the subsequent zones of the reactor until at least 40% by weight of solids have been formed.

Abstract: A case where a high bias voltage is required for a photo-element (3) of a photo-receiver, a high voltage is applied to an amplifier (4) which amplifies a photo-current created by the photo-element, when a power supply is turned on. In a prior art photo-receiver, the amplifier may be broken due to this high voltage. In the present invention, the photo-receiver is provided with a protection circuit (5) comprising a diode (11) connected between a power supply circuit (6) and a photo-element (3), a resistor (12) connected in parallel with the diode (11), and a first capacitor (13) having one end thereof connected to an anode of the diode and the other end thereof connected to a reference potential. Constants of the circuit components are set such that a time constant of the supply of the power to the amplifier (4) is smaller than a rising time constant of the supply of the power to the photo-element (3) and a larger than a falling time constant of the supply of the power to the photo-element (3). Accordingly, the supply of the power to the photo-­element is started after the potential at the input terminal of the amplifier has been established and the potential at the input terminal of the amplifier floats after the supply of the power to the photo-element has been fully extinguished. As a result, the amplifier is not broken at the time of power-on and a surge voltage is not applied to the input terminal of the amplifier at the time of power-off.

Abstract: A white-light image and a fluorescent image are capable of being captured by a single video camera (24), and a single light source (1) for producing exciting light is used to pick up the fluorescent image and monitor arrival of particles to the image capturing area. Specifically, besides a strobe light source (2), a light source, the output of which normally is low, is provided for exciting fluorescence and for monitoring cell flow-through. An image intensifier is used in the light-receiving system of the fluorescent image and is supplied with a voltage the size and timing of which are controlled in such a manner that the irradiation of a cell with the strobe light when the white-light image is captured will not have an adverse effect upon the aforementioned light-receiving system. This makes it possible to pick up two images each in a different zone on the light-receiving surface of image capturing means.
