Abstract: An apparatus for gasifying solid carbonaceous material in a circulating fluidized bed reactor (1). Particles are separated from the product gas at least in two stages so that in the first stage (2), mainly coarser, so-called circulating particles are separated and returned to the reactor. In the second stage (5), fine carbonaceous and ash-containing particulates are separated from the gas and are made to agglomerate at a raised temperature. Coarser particles thus received are returned to the reactor through a return duct (3, 33) together with circulating particles. Agglomeration is effected in a chamber (30), where a fluidized bed (31) composed of coarse particles is maintained. Fine particulate material (38) and oxygen containing gas (39) are introduced into the free upper part of the chamber so as to form a flame (40). The point of the flame penetrates into the fluidized bed. The ash material contained in the fins particulate material melts, and is conducted to the bubbling fluidized bed (31).

Abstract: The objective of the invention is a method for detection of alien matter contents in gas, in which method the gas and the substances contained in it are ionized in an ionization room (1). By the present methods impurities in gases cannot be determined fast and in small concentrations. In the method of the invention the ions contained in the gas are separated in a separation section (2) into positive and negative ions, of which at least the ions of either sign are led into a narrow analyzer channel (4). There, due to the capillary force, they are forced to move in the middle section of the channel, from where they are deflected by electric fields of different strength caused by different voltages (U1-U10) into an electrode located at the edge of the channel, where they cause ion current (I1-I10). On the basis of ion currents a current spectrum is made, on the basis of which different substances are detected and their concentrations determined with the aid of corresponding spectra obtained with standard samples of different substances.

Abstract: Polymeric structures having interpenetrating matrices in cured form comprising an epoxy-polyamine network and a polysiloxane network. The interpenetrating network physical and chemical properties are improved over those of either polymeric component alone. The network can be prepared by simultaneously reacting epoxy resin having at least two oxirane groups with amine curing agent, and having present at least 0.1 equivalent of silane, water being substantially uniformly distributed throughout the mixture in an amount sufficient to bring about substantial hydrolytic polycondensation of the silane to form a cross-linked interpenetrating polymer network. The amine curing agent may be substituted wholly or in part by aminosilane. Sources of silane may include aminosilane and epoxysilane. Relative reaction rates of formation of the polymeric networks are controlled, to get good intertwining of the two polymers.

Title: Magneto-optic recording medium and manufacturing method
Inventor: TSUTSUMI KAZUHIKO
IPC: G11B11/14
Filed: 1990-02-20
Granted: 1996-09-03
Abstract: A magneto-optic recording medium has a recording layer for storing information and an initializing layer which is uniformly magnetized in a fixed direction during the manufacturing process.  The medium is directly overwritable by modulation of a laser beam between two power levels.  In low writing, the recording layer is heated sufficiently to acquire the magnetization of the initializing layer by means of exchange coupling between the layers.  In high writing, the recording layer is heated to a higher temperature, above its Curie temperature, and is magnetized in the opposite direction by an external bias magnet.  Additional magnetic layers may be provided between the recording and initializing layers to facilitate high writing.  Since the initializing layer is always magnetized in the same direction, no external initializing magnet is required.

Abstract: ABSTRACT      An add/drop interface is connected in series with a data bus and is constructed for receiving an add/drop module.  The add/drop interface includes a data selection multiplexer which receives through data from the data bus and add/drop data from the module and selects the proper output data in response to a signal received from a controller in said interface.  The controller provides a signal to drive the data selection multiplexer to select the add/drop data only after all transient signals resulting from module connection have dissipated.  The controller also provides error checking so that the through data is selected if errors are detected.  Timing circuitry in the interface maintains the correct phase relationship between through data and add/drop data.

Granted: 1995-02-14
Abstract: Abstract of the Disclosure In an optical fiber ribbon fusion-splicing device, a TV camera is set such that the horizontal direction of an image sensor contained in the TV camera in which direction a horizontal scanning is carried out and the resolution of the image sensor is higher than that in the vertical direction in which a vertical scanning is carried out is a direction perpendicular to the coaxial direction of a pair of grooved supporting members for supporting fibers of a pair of optical fiber ribbons to be fusion-spliced. Thus, when the fibers of the pair of optical fiber ribbons are set on the supporting members in the coaxial direction thereof, the horizontal direc-tion of the image sensor is perpendicular to the coaxial direction of the fibers of the optical fiber ribbon. Since, therefore, misalignment of the fibers is involved in the high resolution direction, the misalignment can be detected with high precision, without decreasing the power factor of the image sensor.
