An object is to provide a rubber composition that is capable of significantly improving mechanical properties. Another object is to provide a rubber belt that has excellent mechanical properties. Provided are a rubber composition, and a rubber belt formed by using the rubber composition, which is incorporated with a rubber component containing an ethylene/α-olefin copolymer, and an organically treated clay mineral organically treated with an organic ammonium ion, wherein the ethylene content of the ethylene/α-olefin copolymer is in a range of 60-85% by mass, the rubber component has a Mooney viscosity of 10-55 at 125° C., and the organically treated clay mineral is incorporated in 6-30 parts by mass per 100 parts by mass of the rubber component.
摘要:
A lead frame (100) for a semiconductor device is formed by applying nickel plating (102), palladium plating (103), and gold flash plating (104) substantially entirely to lead frame body (101) such as copper thin plate in this order, and further applying silver plating (105) selectively to part of an inner part that is to be enclosed with a package of the semiconductor device. The lead frame (100) may also include a base of the package. The silver plating contributes to an excellent light reflectance and wire bonding efficiency of the inner part, whereas the gold flash plating contributes to an excellent resistance to corrosion and soldering efficiency of an outer part that is outside the package.

摘要:
A wireless communication system includes a first wireless station including antenna elements, transmission units corresponding to the antenna elements, and a transmission directivity control unit that controls transmission directivity of the antenna elements, and second wireless stations each including a reception power measurement unit that measures a reception power. The transmission directivity control unit determines the transmission directivity of each of the antenna elements so that a signal does not reach a particular second wireless station among the second wireless stations. The transmission units generate wireless signals using the transmission directivity. The antenna elements transmit the generated wireless signals. The reception power measurement unit measures the reception power in a period that is set so that a signal does not reach the particular second wireless station by using the directivity, and detect the presence or absence of interference caused by the low accuracy of channel information.
