Abstract: There is provided a printed wiring board including an outermost conductive layer that includes a plurality of conductive pads, a first conductive layer that includes a first inner-layer wiring and is stacked on the conductive layer, a second conductive layer that includes a second inner-layer wiring and is stacked on the conductive layer and the first conductive layer, a first signal via that connects one of the conductive pads and the first inner-layer wiring with each other, a second signal via connecting another one of the conductive pads and the second inner-layer wiring with each other, and a stitching via that is connected to a ground. The first inner-layer wiring and the second inner-layer wiring form a common wiring route in which the first inner-layer wiring and the second inner-layer wiring are stacked and disposed in a connection area in which the conductive pads are arranged.

Abstract: An object of the present invention is to provide an agent serving both as a compatibilizer and an impact strength-imparting agent, which is freed from layer separation phenomenon and capable of improving compatibility to a polyphenylene ether and/or a polyolefin without detriment to weld tensile strength and low temperature impact strength. Another object is to provide a resin composition, which is obtained by blending the agent serving both as a compatibilizer and an impact strength-imparting agent with other thermoplastic resin, and which is superior in its impact resistance, particularly impact strength at low temperature, heat resistance and processability.

Abstract: A lubricant for a refrigerator using ammonia as the refrigerant, which contains an additive selected from antioxidant, anti-wear additive and metal deactivator, and the polyether compound represented by the following general formula (1) or (2): X{—O—(AO)n—H}p??(1) X{—O—(AO1)a—(AO2)b—H}p??(2)

Abstract: To provide a refrigerating unit using ammonia as a refrigerant, which uses a lubricant that is excellent in the compatibility with an ammonia refrigerant as well as in the lubricity and the stability.

Abstract: To provide a polyalkylene glycol-based refrigerant oil for refrigerators using ammonia as a refrigerant.

Abstract: A process for producing a proteinous material which comprises coarsely grinding fish bodies including bones and/or shells, from which the internals had been removed optionally together with heads and/or skins, defatting said coarsely ground fish bodies if required, and either (1) fermenting said coarsely ground fish bodies with an enzyme and/or a microorganism, inactivating said enzyme and/or microorganism and then finely grinding the fermented material; or (2) finely grinding said coarsely ground fish bodies, fermenting the same with an enzyme and/or a microorganism, and then inactivating said enzyme and/or microorganism; or (3) finely grinding said coarsely ground fish bodies while fermenting the same with an enzyme and/or a microorganism and then inactivating said enzyme and/or microorganism is disclosed.
