  • Publication number: 20120287659
    Abstract: Disclosed is a reflective film laminate, which has a pure Ag film or an Ag-based alloy film as a first layer on a base body, and an oxide film of a metal of one or more kinds selected from among Zr, Cr, Nb, Hf, Ta, V, Ni, Mo, W, Al and Si, as a second layer on the first layer. The thickness of the second layer is 0.1 to 10 nm, and deterioration of the reflection ratio of reflective film laminate is 30% or less by having the second layer provided therein. The reflective film laminate is provided with a protection film, which has a high initial reflection ratio, excellent sulfuration resistance and heat resistance, and an extremely small number of pin holes. As a result, the reflection ratio of the reflective film laminate is not easily deteriorated due to aggregation of Ag atoms of the Ag film.

  • Publication number: 20120036364
    Abstract: In a system where a communication device performs secure communication by using a digital certificate, to enable a device of a communication party to verify that a self certificate is certainly generated by a device indicated on the self certificate even if the self certificate is not delivered offline in advance. Based on a master key and a public parameter, a communication device generates an ID-based encryption private key for which a device unique ID is used as a public key. Then, the communication device generates the digital signature of an RSA public key as a ID-based encryption signature by using the ID-based encryption private key. Then, the communication device generates an RSA self signature for the RSA public key, an expiration date, a host name, the device unique ID, and the ID-based encryption signature as the target. Then, the communication device generates a self-signed certificate to include the ID-based encryption signature and the RSA self signature.

  • Patent number: 6945240
    Abstract: In an exhaust gas recirculation apparatus for an internal combustion engine mounted with a turbocharger in which a turbine is disposed in an exhaust passage and a compressor is disposed in an intake passage, when the exhaust gas recirculation is carried out, a port formed at the intake passage on the downstream side of the compressor is opened. As a result, since an intake air on the downstream side of the compressor is released to the atmosphere and a negative pressure in the exhaust passage is lowered, a differential pressure between an exhaust pressure in the intake passage and the negative pressure in the intake passage is increased, to improve an exhaust gas recirculation rate, so that a NOx discharge amount can be reduced.
