Publication number: 20240155765Abstract: To enhance the degree of design freedom of an outermost conductor layer in an electronic component embedded substrate. An electronic component embedded substrate includes conductor layers, insulating layers each of which is positioned between adjacent two of the conductor layers, and an electronic component embedded in the insulating layer. The conductor layer is positioned in the uppermost layer and includes a plurality of terminal electrodes exposed to one surface side. The insulating layers are each made of a core material obtained by impregnating a core with a resin material, while the insulating layers are made of a resin material not containing a core. Since the insulating layer is made of a resin material not containing a core, the diameter of a via conductor formed in the insulating layer can be reduced. Thus, even when the plurality of terminal electrodes are formed in the conductor layer with a small pitch, the routing distance of wires can be reduced.Type: ApplicationFiled: February 22, 2022Publication date: May 9, 2024Inventors: Kazutoshi TSUYUTANI, Naoyuki ISHIKAWA, Takuro AOKI, Reo HANADA

Patent number: 10739285Abstract: A method for accurately measuring the thermoplasticity of a coal whose thermoplasticity has been difficult to evaluate and determining whether the coal that is to be measured does not significantly reduce the coke strength when used for a coal blend is disclosed. Also disclosed is a method for evaluating a coal used as a raw material for coke and includes using a physical property value relating to a thermoplasticity of a coal as an index for evaluating the coal, wherein a primary or secondary amine including an aromatic ring have been added to the coal, thereby enhancing the thermoplasticity of the coal.Type: GrantFiled: February 17, 2016Date of Patent: August 11, 2020Assignee: JFE STEEL CORPORATIONInventors: Yusuke Dohi, Kiyoshi Fukada, Takashi Matsui, Mikiya Nagayama, Narumi Nanri, Kazutoshi Hanada

Patent number: 10414986Abstract: A method for manufacturing coke having a high strength and excellent extrusion capability. The method includes a preparing step of blending two or more coal brands to prepare a coal blend, a stirring and mixing step of stirring and mixing the coal blend to disintegrate at least a part of pseudo-particles that have been formed by agglomeration of coal particles in the coal blend, and a carbonizing step of charging the stirred and mixed coal blend into a coke oven to carbonize the stirred and mixed coal blend. Additionally, a mixing apparatus is used in the stirring and mixing step that has a capability of controlling a degree of mixing of the coal blend to be 0.85 or more at 60 seconds after start of a mixing operation. The degree of mixing is calculated by the following equation (1): degree of mixing=(?C0??C)/(?C0??Cf)??(1).Type: GrantFiled: May 15, 2015Date of Patent: September 17, 2019Assignee: JFE STEEL CORPORATIONInventors: Yusuke Dohi, Yoshiko Maeta, Kazutoshi Hanada, Kiyoshi Fukada, Takashi Matsui, Michio Honma, Masahiro Shinohara
