Abstract: PROBLEM TO BE SOLVED: To prevent the thermal deformation of the immersion nozzle by clogging the gap caused between the immersion nozzle and an opening of a preheating furnace with an annular flange part so as to eliminate that a holder of the immersion nozzle is extremely heated with flame and hot wind. SOLUTION: This cover member 1 is mounted to the immersion nozzle 27, which is fitted to a bottom part of a molten metal accommodating laddle. Next, a preheating furnace 30 is moved to an underside of the immersion nozzle 27 and the immersion nozzle 27 is inserted to an opening part 32a of the cover body 32 of the preheating furnace 30. At this time, a flange part 3 of the cover member 1 mounted to the immersion nozzle 27 is inserted up to abut on the upper face of the cover body 32 of the preheating furnace 30. By this method, the gap formed between the immersion nozzle 27 and the opening part 32a of the preheating furnace 30 is clogged. As a result, flame and hot wind is not blown out outside the preheating furnace 30 because the gap between the immersion nozzle and the preheating furnace is clogged by the cover member 1.

IPC: H04J3/00
Filed: 1984-02-17
Abstract: PURPOSE:To relieve the load of the software of a main CPU by using a time division multiplex transmission circuit separate from the main CPU so as to generate a parity word or the like to a transmission data and check the correctness of received data. CONSTITUTION:A multiplex transmission LS12 receiving a data from a terminal device executes the discrimination whether or not a format of the reception data is a correct form (format check). As the result of format check, if it is discriminate that a correct correspondence result is obtained, only a data part DATA is returend to the main CPU1 or the data DATA and a PT are returned to the main CPU1 by setting of the reception function the same as the transmission function. Since the main CPU1 can know accurately the state of the terminal device by referencing the returned data, proper control in response to the application of an object device being a slave station is attained.

Abstract: PURPOSE:To correct automatically an angle shift by receiving an original coordinate signal and a layout sheet coordinate signal by an input, deriving an angle made by a straight line for connecting the respective two points and an (x) axis, deriving an angle difference made by both straight lines, and executing a control of a direction for eliminating the angle shift. CONSTITUTION:A relative coordinate of a set position on a finished layout sheet, on an original 7 stuck to a plane scanner plate 8 is detected by a relative coordinate detector 2, and by receiving this detecting result, an original coordinate signal generating circuit 4 generates an original coordinate signal 4'. An angle shift signal operating circuit 5 receives these original coordinate signals and a layout sheet coordinate signal 9 by an input, derives an angle made by the respective straight lines and an (x) axis, also derives a difference of angles corresponding to two straight lines, and sends a signal corresponding to this angle shift theta to a rotation command outputting circuit 6 of the next stage. The rotation command outputting circuit 6 sends out a control command signal 6' of a direction for eliminating this angle shift theta, to a rotation driving device 3. The rotation driving device receives it, and drives to rotate a plane scanner plate 8 stacking with the original 7. In this way, as for the original 7 and the plane scanner plate 8, a rotation angle shift to a finished layout sheet 10 is corrected.

Title: Receiving device for optical communication
Inventor: TACHIKAWA MAKOTO
IPC: H04B10/564
Filed: 1978-03-13
Abstract: PURPOSE:To increase the reception range by securing the adjustment of the operation point for the preamplifier. CONSTITUTION:When the light receiving power becomes higher than the reference level, comparator 22 generates the output to turn on FET switch 21. As a result, feedback resistance value Rt of amplifier 15 features the parallel resistance value of resistance 20 and 26. This parallel resistance value becomes less than the value of resistance 20, i.e., the feedback resistance value when switch 21 is off. Thus, maximum reception power Pmax increases according to the equation (1); while the reception power becomes less than the fixed level, switch 21 is turned off to feature the value of resistance 20. Thus, the maximum reception power is decreased.

Abstract: PURPOSE: To selectively and sequentially extract and separate even co-existing uranium and a rare earth element using a supercritical fluid as a medium by providing a plurality of extraction processes of different extraction efficiency. CONSTITUTION: Tributyl phosphate(TBP) and carbon dioxide are mixed through a syringe pump 1 and a plunger pump 3, so as to obtain TBP concentration at 3vol%, and a mixture so obtained is processed into a supercritical fluid at 60 deg.C and 150atm, by use of a preheater coil 5. Then, the fluid is made to flow into a sample solution in an extraction vessel 6 at a constant flowrate of approximately 1.1ml/min. Then, an effluent from the vessel 6 is passed through a filter 7 and a restrictor 8 and, then, uranium and a rare earth element are separately arrested with an arrester vessel 9. Also, carbon dioxide is separately collected from a gas outlet into a gas arrester. In this case, the filter 7 has a function of arresting particulate solid substances contained in the extracted fluid, in order to prevent the internal space of the capillary of the restrictor 8 from being clogged.  Furthermore, the restrictor 8 gasifies carbon dioxide in the supercritical fluid after the return thereof to a normal temperature and pressure state.
