IPC: F01D5/28
Filed: 1978-07-25
Abstract: PURPOSE: To reduce the consumption of the wing tip and to prevent the reduction of turbine-efficiency and the increase of the radiation in the atomic generating plant by providing a boriding process layer at least at the front edge of the steam turbine runner.  
     CONSTITUTION: A runner body 1 is formed of 12% Cr basic steel of the maltensite system which is commonly used in a conventional steam turbine runner. The runner body 1 is formed at the front edge with a boriding process layer which constitutes an errosion shield portion 2 or jointed with an errosion shield body 3 preliminarily formed with a boriding process layer thereon by soldering an welding 4. Thus constructed turbine runner is difficult to consume due to the errosion accompanying the  turbine rotation and prominent in preventing the fall of the turbine efficiency. When used in the steam turbine for boiling water type atomic generating plants, this turbine runner does not increase the radiation in the plant.

Filed: 1979-07-16
Abstract: PURPOSE:To make the height of a casting machine half and decrease casting defects by making the leveling internal strain rate of a slab at each leveling point of the multipoint leveling curving type continuous casting machine less than the specific value. CONSTITUTION:Casting is performed by making the leveling internal strain rate epsilonN expressed by the formula within a range of <=0.35%. The leveling points of a leveling region are 5 points P1-P5, and the curving radii R1-R5 are of respectively different values, becoming successively larger R1-R5. For example, For R1 is made 5800mm. and R5 7100mm.. Here, killed steel of 0.20% C content sizing 410X1,700mm.is cast at a speed of 0.5m/min. The frozen shell thickness at the leveling point P1 is 110mm. and the rate of freezing is in a 40-70% range, and in this case, it is about 54%. If from these conditions the leveling internal strain rate is obtained, by the formula it is 0.28%, below the specific 0.35%. The respective strain rates of P2-P5 become nearly the same values as well. The curving radii at the respective leveling points are beforehand so determined as to satisfy the formula. The height of this curving type continuous casting machine is about 6m, less than about half that of conventional types.

Filed: 1989-04-12
Abstract: PURPOSE:To minimize the disturbing time of a lower rank processor or a higher rank bus by providing an address latch circuit and a data latch circuit to actuate the working of a DMA controller contained in the lower rank processor and an access action to a higher rank memory independently of each other. CONSTITUTION:When a writing operation is applied to a higher rank memory 4, a DMA controller 8 receives a DMA request signal and starts to start a reading operation of a local memory 6. In this case, an internal bus 7 is kept occupied until the input of a ready signal after the end of the reading operation of the memory 6. At the same time, a higher rank bus is kept occupied until the data is written into a prescribed address after a bus grant signal is outputted in response to a bus request signal. So is with a reading operation which is carried out through the memory 4. As a result, the writing/reading operation is carried out to the memory 4 independently of an access action carried out to the bus 7. Thus it is possible to extremely shorten the disturbing time of a lower rank processor 5 and the higher rank bus.
