  • Patent number: 8516245
    Abstract: A validation authority for certificates searches for and verifies paths and certificate revocation lists periodically, and classifies the paths into valid paths and invalid paths in accordance with the results of the validations, so as to register the paths in databases beforehand. Besides, in a case where a request for authenticating the validity of a certificate has been received from an end entity, the validation authority judges the validity of the public key certificate by checking in which of the valid-path database and the invalid-path database a path corresponding to the request is registered. On the other hand, in a case where the path corresponding to the validity authentication request is not registered in either of the databases, the validity of the public key certificate is authenticated by performing path search and validation anew.

  • Patent number: 7533269
    Abstract: In response to a sign request including a digital document from a document-creating device 10, a digital-signed-document exchange supporting server 30 canonicalizes the digital document, calculates a digest value thereof, and returns the digest value to the document creating device. When the document-creating device transmits a digital sign created by encrypting the digest value to the digital-signed-digital document exchange-supporting server 30, the server 30 creates a digital-signed document from the digital sign and the digital document, and returns the document to the document-creating device. On the other hand, in response to a validation request including a digital-signed-digital document and a public key from a sign validating device 20, the server 30 compares a value resulting from the decryption of the digital sign with the public key and a digest value of the digital document canonicalized and returns the result to the sign validating device.

  • Patent number: 7462963
    Abstract: A motor cooling apparatus and method to auto-circulate coolant to reduce the weight and size of the cooling system. The cooling apparatus includes a coolant path disposed at hot areas of the motor. A reservoir tank is located above the coolant path and gravity feeds coolant to the coolant path. Coolant in the vapor phase discharged from the coolant path is liquefied by a condenser located in a coolant return path. Coolant in the liquid phase is expelled to the reservoir tank under pressure of the vapor-phase coolant in the coolant path to provide for the auto-circulating coolant. Expansion pressure of the coolant supplied by an motor inverter can further increase the pressure of the coolant in the discharging coolant path to improve coolant circulation efficiency to prevent dry out in the coolant path.

  • Publication number: 20070199339
    Abstract: A cooling apparatus for cooling a heat-generating member includes a cooling flow path, a condenser, a coolant-returning flow path, a first check valve and a second check valve. The cooling flow path is thermally connected to the heat-generating member. The condenser is connected to a downstream portion of the cooling flow path and condenses a coolant contained in the cooling apparatus after the coolant is evaporated in the cooling flow path. The coolant-returning flow path returns the coolant condensed by the condenser to an upstream portion of the cooling flow path. The first check valve is disposed between the coolant-returning flow path and prevents the coolant from flowing in a reverse direction from the cooling flow path to the first coolant-returning flow path. The second check valve is disposed between the condenser and the coolant-returning flow path and prevents the coolant from flowing in a reverse direction from the first coolant-returning flow path to the condenser.

  • Publication number: 20060254838
    Abstract: A cooling device for a vehicle has a heat exchanger, a duct that forms a passage for air that has passed through the heat exchanger, and a cross-flow fan provided within the duct. The fan draws in the air that has passed through the heat exchanger and blows it out from the duct. The fan is placed outside of a horizontal projection area from the vehicle front to the vehicle rear of the heat exchanger. The duct has an opening portion that opens when the vehicle is at a predetermined speed or more so that the air that has passed through the heat exchanger when the vehicle is at the predetermined speed or more passes through the opening portion without passing through the fan.
