Title: Molten steel stirring method in continuous casting plant
Inventor: YOSHII KENTA
IPC: B22D11/115
Filed: 1980-04-01
Abstract: PURPOSE:To flow molten steel ingot smoothly by superposing the 3rd higher harmonic wave on each of two phases of basic waves having a phase difference. CONSTITUTION:Combined wave currents Iu, Iv, of two phases having a phase difference of a pi/2 electrical angle are flowed to electromagnetic coil 4a, 4b. The current of the (u) phase is the combined wave comprising superposing the 3rd higher harmonic wave Iu2 on the basic wave Iu so as to generate two maximum currents or two minimum current at every electrical angle pi. The current of the (v) phase is the combined wave comprising superposing the 3rd higher harmonic wave Iv2 on the basic wave Iv1 so as to generate two maximum currents or two minimum currents at every electrical angle pi. Electromagnetic forces act in a clockwise direction along with the rotating magnetic field and consequently, the molten steel rotates horizontally in a clockwise direction. In each corner part, the relatively strong magnetic forces are acted in the direction of deviating from each corner part and therefore the inclusion in the corner parts is eased.

Title: Composite network communication system
Inventor: MATSUDA MASAHIRO
Filed: 1987-02-28
Abstract: PURPOSE:To prevent duplicated reception by leaving a reception history to a bidirectional gateway connecting networks mutually and relaying only a leading broadcast among the same broadcast signals in different directions. CONSTITUTION:When a data relay control circuit 221 receives a bit of packet information of broadcast, a storage circuit 223 is searched to check whether or not other data relay control circuit has already received it. When no recep tion exists in the other circuit, the control circuit 221 stores its own reception information into the storage circuit 223 and the packet information of the re ceived broadcast is relayed via a data transmission circuit 203. On the other hand, when the other circuit already receives the information, no relay processing is applied. Thus, the procedure of its own network aud the other network is made identical and no data duplicated reception is generated in the network constituted in a closed loop.

Abstract: PROBLEM TO BE SOLVED: To conduct a constant water level water permeation test quickly and accurately and without risk of destruction even though the hole wall has a low strength, even in case the test is made at a large depth and the earth has a low permeability. SOLUTION: A packer 24 is installed around the lower part of a water pipe 22, and a reducing valve 34 is installed over the packer 24, followed by insertion into a boring hole 20 so as to reach over the ground surface from the position which becomes a test division. The upper and lower parts of the packer in the boring hole are water shut by expanding the packer 24 so that a test division is set. Water is poured by a pump 26 in the condition that the whole cavity of the pipe 22 is filled with water, and a constant pressure adjusted decompressively is generated on the secondary side by the decompression valve 34, and the water head is determined from the difference of the equilibrium water head from the pressure of the test division sensed by a pressure sensor 30 while the rate of flow of the water injected from upon the ground is measured by a flow meter 28.  The coefficient of permeability is determined from the obtained water head and rate of flow.

Filed: 1981-03-26
Abstract: PURPOSE:To increase both the operability and the portability of a camera, by providing a means to hold the detecting part of a detecting mechanism at a prescribed phase in case no film is loaded into the camera. CONSTITUTION:When a film is loaded into a camera, a projected part 38a of a sprocket cam 38 is set at a position as shown in the diagram and the driving force is transmitted from a driving source M to turn the cam 38 counterclockwise. The engagement is impossible between a pin 37 implanted to a lever 35 and a fall part 41a of a slide lever 41 as long as a projection 18b of a slide lever 18 presses an end 31a of a lever 31 although the part 38a and the lever 35 are in contact with each other. As a result, both the cam 38 and lever 18 move continuously. When the part 38a and the lever 35 are in contact with each other, the engagement is released between a clutch plate 5 and a clutch lever 44 since the projection 18b is detached from the part 31a. As a result, the feed of the film is stopped to obtain a steady state.

Abstract: PURPOSE:To shorten an operation time even when the output value of a metering machine is hard to stabilize by finding the best combination at specific timing after an article is thrown in, and operating the best combination again at the next timing where the output value becomes stable. CONSTITUTION:A processor 104a when detecting the generation of a start signal STS outputs a weight value read signal WRS to a multiplexer 102 at the 1st timing.

The processor sums up weight values as to 2<n-1> kinds of combinational pattern and discriminates on whether the combination total value X is within a specific range or not. The weight value read signal WRS is outputted again to the multiplexer 102 at the 2nd timing to read weight values Wi', which are stored in the data memory 104b. Then, weight values Wi' in the best combination pattern are summed up, and the discrimination on whether the total weight value X' is within the specific range or not is made.
