摘要： PURPOSE:To reduce visibility of the connection lines of plural liquid crystal panels. CONSTITUTION:Liquid crystal panels 2 are overlappingly arranged with their wiring connection parts at the rears, transparent and integrated font panels 1 are provided stuck to the fronts of the liquid crystal panels 2, stepped stages 1A are provided on the rear sides of the front panels 1 and in this way, the liquid crystal panels 2 are systematically arranged. In the case of a transmissive type, illuminating panels are provided on the rear sides of the liquid crystal panels 2. Thus, a thin type large sized screen is made without intereference of a nonpixel part and although it is made necessary to reduce the size of a nonpixel part as much as possible when liquid crystal panels are planely arranged conventionally, it is manufactured relatively freely. Also, this technique is applied to any of reflection and transmissive types. Further, protection from dusts, water and outside forces and other effects are realized by the integrated type front panels.

摘要： PURPOSE:To make it possible to perform continuously intermediate polymerization and final polymerization in the same reaction apparatus by partitioning a reaction tank with partitions each having a special structure to form a plurality of chambers, controlling the operating pressures in the respective chambers according to the reaction states of the solutions treated and agitating the solutions in the respective chambers with agitating elements of different structures. CONSTITUTION:A solution to be treated is fed to a reaction tank 5 (from 16) and agitated in a plane crossing the direction of flow in such a manner that it can be exposed to a vapor phase atmosphere in the tank. A tank body 6 is partitioned in the lengthwise direction into a plurality of chambers (e.g. 5a and 5b) with a partition 9 constructed so that it may completely partition the vapor phase in the reaction tank 5 and that it may have a passage 9a for the solution below the surface of the solution. The pressures in the respective chambers (e.g. 5a and 5b) are decreased (through a vacuum nozzles 18 and 19), the operating pressures in the respective chambers are controlled according to the states of reaction of the solutions to be treated in the respective agitated chambers, and the agitation in the respective chambers is performed with agitating elements (e.g. 10a, 10b, 11a and 11b) of different surface areas.

摘要： PURPOSE:To obtain a material having high viscosity continuously forming a homogeneously mixed phase by feeding a liquid having high viscosity and addi tive liquid from an end of a reaction apparatus provided with two revolving shaft to the main body wherein plural stirring blades are arranged to face oppositely but with by each 90 deg. shifted phase to each other. CONSTITUTION:Plural numbers of stirring blade 5 facing oppositely are provided to revolving shafts 5a, 5b arranged in parallel to each other in the main body 3 shifting the position of the blades by 90 deg. to each other and with a small space against the inside wall of the main body 3. Polymer chips supplied to a hopper 7 is fed continuously to an extruder 9 via a rotary valve 8, extruded in the form of a high viscous liquid by being heated and melted. On one hand, an additive liquid fed to the main body 3 is rolled in the high viscous liquid by the effect of the stirring blades 5, and disintegrated to remarkable small particles in accompany with deformation by the shearing of the high viscous liquid, and dispersed uniformly generating extremely large contact surface area and exposing simultaneously its free surface to the additive liquid.

摘要： PURPOSE:To provide a heater which can largely shorten the heating time and has a high quality. CONSTITUTION:A heater body 9 has a heat medium jacket 10 in the outer periphery thereof, and is heated and reatined at high temperature by heat medium or steam. Two-axle gear pump 11 is assembled in a pressure feed chamber 9, and a flared conical rotor 12 formed with respect to the advancing direction of content is assembled in a heating chamber 9b. The inner wall of the chamber 9b is spaced at predetermined interval 18 from the surface 12a of the rotor 12 so that the interval 18 imparts the content passing therethrough by a shearing force produced by the rotation of the rotor 12 in magnitude necessary to abruptly raise the content. Heat medium flown into the jacket 10 from an inlet noszzle 16 is substantially uniformly heating the heater body 9. The content such as polymer to be heated and retained at high temperature is fed by the gear pump 11 in the chamber 9a through the interval 18 between the inner wall of the chamber 9b and the surface 12a of the rotor 12, and heated by the rotation of the rotor 12.

摘要： PURPOSE:To ensure the seal of liquid at parts where a rotary shaft penetrates through dams by a method wherein the shaft sealing device is used for a manufacturing device polymerizing a polymer such as polyester or the like continuously. CONSTITUTION:A housing 18 is attached to the dams 16a, 16b fixedly and screws 19a, 19b are attached to the rotary shaft 11 integrally. The screws 19a, 19b are provided with screw grooves of opposite directions so that liquid in a fore stage (left side in the diagram) is advanced to the right and the same in the aft stage is advanced to the left. The housing 18 is also provided with a liquid extracting hole 20 near a place where the screws 19a, 19b contact with each other so that the liquid, forcibly advanced by the screws 19a, 19b, may be extracted continuously by a small amount. Since the device is thus constructed, the sure sealing may be effected.
