摘要:
A printed wiring board is manufactured by a method in which a laminate body having a first insulation layer and a conductive film is provided. An alignment mark is formed in the laminate body by removing at least a portion of the conductive film. An electronic component is placed on an adhesive layer provided on the first insulation layer at a position determined based on the alignment mark. After the electronic component is enclosed inside an opening of the second insulation layer, a via hole exposing a terminal of the electronic component is formed at a position determined based on the alignment mark used to determine the position of the electronic component. A via conductor is formed in the via hole, and a conductive layer is formed on the conductive film and patterned to form a conductive circuit connected to the via conductor.

The present invention relates to a method for efficiently extracting and producing lipid components from crustaceans. A method for producing lipids, characterized by obtaining a squeezed liquid by squeezing a whole crustacean or a part thereof, heating the squeezed liquid to a temperature at which proteins contained in the squeezed liquid coagulate, carrying out solid-liquid separation so as to separate the heated squeezed liquid into a solid component that contains lipid components and an aqueous component that contains water-soluble components, washing the resulting solid containing lipids or a dried product thereof with water, dehydrating and/or drying, and then extracting lipids from the solid containing lipids or the dried product thereof.

摘要:
Flaws in a fluid controller caused by nonmetallic inclusions in material during machining of a contact surface of a valve seat are prevented by forming the valve seat of corrosion-resistant high-cleanliness material. The valve seat of the fluid controller is formed from corrosion-resistant alloy with 0.05% or less cleanliness and containing in weight ratio 12.90-15.00% Ni, 16.50-18.00% Cr, 2.00-3.00% Mo, 0.02% or less C, 0.30% or less Si, 0.40% or less Mn, 0.03% or less P, 0.003% or less S, 0.25% or less Cu, and 0.01% or less Al. Fluid leakage is almost completely prevented (100%) by such a valve seat.
摘要:
There is provided an etching method for a semiconductor product. The semiconductor product having, on a substrate, an SiO2 layer, and an Si layer with a free surface and directly stacked on the SiO2 layer is prepared. The Si layer is etched. Etching is performed while supplying an etching solution from a side of the free surface using high-concentration fluonitric acid as the etching solution, and etching is continued by switching to fluonitric acid having a concentration lower than that of the fluonitric acid immediately before or after at least part of a surface of the SiO2 layer immediately under the Si layer is exposed.
