摘要:
A multilayer coil component is provided to have high reliability and in which internal stress arising from the difference in firing shrinkage behavior and/or thermal expansion coefficient between ferrite layers and internal conductor layers is alleviated without forming conventional voids between the ferrite layers and the internal conductor layers. A method of manufacturing a multilayer coil includes a step of isolating interfaces between internal conductors and surrounding ferrite by allowing a complexing agent solution to reach interfaces between the internal conductors and the surrounding ferrite through side gap portions from side surfaces of a ferrite element including a helical coil. The complexing agent solution contains at least one selected from the group consisting of an aminocarboxylic acid, a salt of the aminocarboxylic acid, an oxycarboxylic acid, a salt of the oxycarboxylic acid, an amine, phosphoric acid, a salt of phosphoric acid, and a lactone compound.

摘要:
In order to quickly and economically evaluate cleanliness of a metal with high representativity when quantities, compositions, etc., of non-metallic inclusion particles existing in a metal and resulting in product defects are evaluated by a sample collected during the production process of the metal, the present invention provides an evaluation method involving the steps of levitation-melting a metal piece for a predetermined time by cold crucible levitation-melting means, discharging non-metallic inclusion particles contained in the metal piece to the surface of a molten metal, and directly analyzing a curved and non-smooth sample surface after solidification by a fluorescent X-ray analysis method using an energy dispersion type spectroscope, or by other chemical or physical measurements, to measure or analyze the quantities of elements constituting the non-metallic inclusion particles and to determine quantity of the non-metallic inclusions.

Disclosed herein is a method of sequentially and continuously determining the concentrations of carbon, hydrogen, and nitrogen in molten steel using a single apparatus. Disclosed also herein are a method and an apparatus for determining trace amounts of carbon in molten steel which are the specialized application of the principle used for the above-mentioned method.Said method comprises bubbling through molten steel a carrier gas selected according to any specific element to be determined in molten steel, recovering the carrier gas containing the specific element, circulating or passing the recovered carrier gas through a gas circulating circuit so that the concentration of the specific element in the carrier gas reaches an approximate or complete equilibrium with the concentration of the specific element in molten steel, determining the concentration of the specific element by the means to determine the concentration of one or more specific elements, (and in the case of determination of several elements) discharging the carrier gas from the gas circulating circuit and repeating said steps with a renewed carrier gas to determine the remaining elements to be determined.

摘要:
Oxygen or a mixed gas containing oxygen, or a chemical flame produced by a mixture of a combustion gas and a combustion-assisting gas containing oxygen, is blown against the surface of molten iron to cause radiation emission. The radiations are divided into components of different wavelengths, and the resulting emission spectra are measured to determine the composition of the molten iron.

摘要:
A scanning line converting system comprises down-converters arranged in parallel for converting an input high definition television signal to a current television signal, and double-frequency converting sections for respectively doubling the frequency of the down-converted current television signals, for synthesizing them, and for delivering the synthesized signal as a non-interlaced video signal. The non-interlaced video signal can be obtained by properly controlling a vertical filter which is a part of the down-converter with no additional interlace/non-interlace converting unit.
摘要:
An automatic photometric analyzer is disclosed using an automatic exchanger holding a sample solution. A recorder, a photometer, an injector for the sample solution, and supply systems for pure water and coloring solutions are used. Additionally, valves under control of an automatic controller properly control the flow and the solution to provide a simple and practical apparatus with rapid automatic operation for analysis. The injector delivers reactant solutions to a reactor from which reactant is circulated through the photometric means to measure the absorbency thereof and back to the reactor.
