Title: Method for predicting slopping in smelting reduction
Inventor: IWASAKI KATSUHIRO
IPC: C21B13/00
Filed: 1988-12-21
Abstract: PURPOSE:To accurately predict the development of slopping under having time to spare by supplying gas into a furnace from gas purge holes arranged in the furnace wall at the position higher than the slag surface level and detecting pressure variation of supplying side. CONSTITUTION:The prescribed raw material is charged into a smelting reduction furnace 1 to execute the smelting reduction with top blow lance 2, side blow tuyere 3 and bottom blow tuyere 4. Then, the gas purge holes 5a, 5b are arranged in the furnace wall at the position higher than the slag surface level forming at the time of the steady operation and the prescribed flow rate of the gas is supplied at each supplying system 6. By this constitution, when the slag surface level raises by foaming the slag as a signal phenomenon of the slopping, the gas purge hole 5a starts to clog with the slag and gas pressure at the supplying side is rapidly raised. The variation of this gas pressure is measured with a pressure gage 7 and at the time, when the measured pressure exceeds the reference value, the development of the slopping is predicted. By this method, the development of the slopping can be accurately predicted before about 1-2min and the suitable preventing countermeasure is taken.

Title: Fusible link
Inventor: MIZUGUCHI YASUSHI
IPC: H01H37/74
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To surely separate conductors from each other before an insulating cover emits smoke when excess current is carried between conductors to break the excess current, and reduce the manufacturing cost of an electric wire. SOLUTION: A fusible link 11 consists of a breaking part 15 sealed between conductors 13, 14, gas 16 which expands by heating when the temperature of the conductors 13, 14 is raised by flowing of excess current, and a breaking conductor 17 which electrically connects a pair of conductors 13, 14 and deforms by the expansion of the gas, and separates conductors each other. Since the gas 16 is quickly heated and expands when excess current flows and deforms the breaking conductor 17 to separate the conductors from each other, excess current is surely broken before an electric wire emits smoke. Since production of an insulating cover with an insulating material with high heat resistance is made unnecessary, the manufacturing cost of the electric wire can be reduced.

Filed: 1988-12-20
Abstract: PURPOSE:To reduce a detectable particle size by mounting a polarizing element between a conversion part for photoelectrically converting the condensed beam emitting from a flow cell and the flow cell. CONSTITUTION:The beam 28 emitted from a flow cell 1 consists of the transmitted beam 28a generated by the transmission of converged beam 26 through the flow cell 1 and the forward scattering beam 28b from fine particles of the beam 26. The beam 28a becomes linear polarized beam coinciding with the vibration surface of laser beam 24 and the beam 28b becomes non-polarized beam. That is, the beam 28b within an angle range of 2thetaapprox.=20 deg. becomes non-polarized beam and the linear polarized beam component coinciding with the beam 28a in a vibration surface is absorbed by a polarizing plate 30 and the residual polarized component is incident to a condensing system 90. The beam 28a is blocked by the plate 30 to be not incident to the lens system 10 and the angle beta of expanse of the beam 28a is smaller than 2theta and the lens system 10 condenses the beam emitted within an angle range of 2theta from the flow cell 1. Therefore, by the incidence of the beam 28b uniquely determined corresponding to a particle size parameter to a photoelectric conversion part 2, the particle size of fine particles 2 and the number of said particles can be measured over a wide range by an output signal 12b.

IPC: H01L39/22
Filed: 1990-11-26
Abstract: PURPOSE:To embody a planer structure by which an integrated three-terminal superconducting element by determining the distance between superconductive electrodes where an oxide normal conducting section is sandwiched to be longer than the attenuation length of the amplitude of the probability of presence of a superconductive electron pair and to be shorter than a value ten times the attenuation length.

A gate insulation film 3, which includes the groove is formed on the film 3. A gate electrode film 5 is formed in the upper part of the groove. When positive voltage is applied to an oxide conducting three-terminal device, the carrier concentration of the layer 2 is reduced so that the effective attenuation length may be shortened, which can reduce the superconducting current, thereby allowing it to work as a superconducting three-terminal device. Therefore, this device can be used as a basic device for a high speed digital logical circuit, a memory circuit, an analog circuit or a squid which detects a magnetic signal or a sensor which detects a microwave.

Filed: 1990-11-26
Abstract: PURPOSE:To obviate tremendous algorithm structure in a conventional system and simplify system structure by making the system learn vehicle motion by means of a neural net and totally controlling a vehicle depending upon the result. CONSTITUTION:To a neural net A, the results of vehicle motion, i.e., yaw angle speed, rolling angle speed, pitch angle speed, lengthwise acceleration, lateral acceleration vertical acceleration and vehicle speed are input. Then, the neural net A outputs vehicle control parameters, i.e., front wheel steering angle, rear wheel steering angle, throttle opening degree, fuel injection quantity, ignition time, cylinder pressure and brake pressure. Whether the output vehicle control parameters coincide with teacher signals, which are actual experimental values, or not is verified. As a result, if the calculated values do not coincide with teacher signals, the weight of the neural net A is corrected so that the differences between their values may be less than permissible levels. After that, actuators are made to operate by outputting corrected ideal control signals to control vehicle motion characteristics.
