  • Patent number: 8943818
    Abstract: A hydraulic device includes a switch-over valve 1140 provided at a section of a sub-passage 1105 located downstream of a location where a first bypass passage 1117 is connected and located upstream of a primary regulator 1110. The switch-over valve 1140 is switched between a blocked state, where supply of hydraulic oil to a section of the sub-passage 1105 located downstream of the switch-over valve 1140 is blocked, and a communication state, where supply of hydraulic oil to the section of the sub-passage 1105 located downstream of the switch-over valve 1140 is permitted. In the hydraulic device, when the switch-over valve 1140 is switched to the communication state, as a discharge performance of a main pump 1102 increases, a first check valve 1118 closes. Supply paths for hydraulic oil discharged from the sub-pump 1103 are automatically switched in accordance with the discharge performance of the main pump 1102.

  • Publication number: 20140156988
    Abstract: A method, system, and/or computer program product provides medical information on a communication network. Encrypted medical information in a decryption request is received from a first computer connected to the communication network at a second computer, the second computer holding decryption information. The second computer determines whether or not the second computer holds decryption information for decrypting the encrypted medical information. In response to the second computer determining that the second computer holds the decryption information, the second computer checks with a third computer as to whether the first computer is authenticated.
