Title: High-speed multiplex transmission system
Inventor: GOTOU YOSHIMI
IPC: H04L29/02
Filed: 1984-02-17
Abstract: PURPOSE:To process data at a high speed within a master station by connecting a main memory part and a transmission part with an exclusive data bus within the master station and connecting only a control bus to the transmission part among normal buses. CONSTITUTION:The data transmitted from a slave station is supplied to an input/output data area of a main memory part 13 from a transmission part 14 via a transmission line 2. In this case, an exclusive data bus 16M set between both parts 13 and 14 is used. In a data output mode the data is read out of an output data area. In this case, the part 14 works asynchronously with a central control part 11. This eliminates the waiting time due to the occupancy of a data bus 16D (as well as a control bus). For the working of the part 11, only an input/output control part 15 and buses 16C and 16D are occupied in an input/ output mode of external data, for example. Thus data can be transmitted at a high speed.

Title: Casting mold for ingot making and making method thereof
Inventor: KOJIMA SHINJI
IPC: B22D27/04
Filed: 1983-02-21
Abstract: PURPOSE:To prevent formation of a gap between the surface of a steel ingot and water cooled copper plates and formation of an internal defect in the steel ingot by sandwiching a set of opposed long side molds inscribed with the water cooled copper plates with a set of short side molds and pressing the long side molds from the outside to the inside. CONSTITUTION:When a molten steel 16 is charged from a charging pipe 18 through a runner 20 into a casting mold, the molten steel begins to start solidifying from the part in contact with the inside wall of the casting mold and double molding boards 14, thus forming a solidified shell 16A toward the lower part from a heat retaining layer 15 on the top surface. A gap is formed between the shell 16A and water cooled copper plates 6 owing to shrinkage of the shell 16A upon completion of charging of the steel 16. Tightening cylinders 8 of short side molds 4 are then loosened and pressing devices 10 of long side molds 2 are acturated to press the opposed molds 2 from the steel ingot from the outside to the inside. The gap is formed again even after the pressing operation of the molds 2 and the plates 6A and therefore the pressing operation is performed continuously or repeated intermittently several times to eliminate or minimize the gap, thereby accelerating the solidifying speed.

Title: Method and device for leakage test of container
Inventor: INOUE MASAHIRO
IPC: G01M3/32
Filed: 1981-02-26
Abstract: PURPOSE:To discriminate the presence or absence of leakage of a container in a quick and accurate way, by inspecting the state of reduced pressure in the container within a prescribed test time after setting the air pressure in the container at the test pressure. CONSTITUTION:The air discharged out of a pump 1 is branched to a working machine system circuit A and a test system circuit B. In the circuit B, a valve 11 is opened in a state under which the air reduced down to the set pressure by a valve 12 is supplied to a pipeline 13. As a result, the air having the pressure higher than the test pressure P is led into a container C through a pipeline 15. When the inside of the container C reaches a prescribed level, the valve 11 is closed by a switch 22. Then a valve 16 is opened to slowly increase the pressure in the container C. After this, the valve 16 is closed when the pressure at the inside of the container C reaches the set level of a switch 23 which is higher than the pressure P. Then a valve 18 is opened to extract the air until the pressure inside the container C reaches the set level of a switch 24. Thus the valve 18 is closed when the pressure at the inside of the container C reaches the test pressure. Then a timer works to start a test of leakage.

IPC: G21C3/32
Filed: 1989-02-07
Abstract: PURPOSE:To flatten the output distribution in a diametral direction by fixing many fuel pins with plural stages of grids in an axial direction, enclosing the pins with an outside cylinder and providing partition walls which partition the fuel pins to the plural regions in the outside cylinder. CONSTITUTION:In this fuel assembly about 10,000 pieces of the fuel pins 1 are fixed apart suitable intervals from each other by means of the grids 6 provided in plural stages in the axial direction in the case of using this fuel assembly in the core of a nuclear reactor for power generation which outputs, for example, 100MW electric power. The mutual interferences between the outside cylinder 8 and the fuel pins 1 and between the partition walls 7 and the fuel pins 1 are, therefore, hardly generated in spite of the expansion during the operation of the reactor. Since the fuel pins 1 are partitioned to plural regions by the outside cylinder 8 and the partition walls 7, the distribution of the flow rate of the coolant for flattening the diametral output distribution is possible.
