Abstract: A user terminal displays on its display unit a target web page including an authentication information input field into which input authentication information is inputted by the user terminal. The user terminal judges first to third validity levels for a plurality of login history information by referring to a login information list and a service group information. The user terminal selects a corresponding process from a plurality of predetermined processes for the input authentication information based on existence or absence of the login history information in the first or second validity level and on a result of checking the input authentication information with login information in the login history information in the first to third validity levels. The user terminal executes the corresponding process.

Abstract: A pipe coupling member for high-pressure fluid such as liquefied hydrogen includes a seal ring having a highly effective sealing function to prevent leakage of the fluid. The seal ring (72) is set in a seal ring setting space (39) defined by a second radial surface (36) and a seal ring setting surface (38) of a first tubular member (20), a forward end surface of a second tubular member (22), and the outer peripheral surface of a valve seat member (24). A forward end portion of the second tubular member (22) is provided with a communication hole (84) radially penetrating the forward end portion. The pressure of the high-pressure fluid on the downstream side of a valve seat surface (52) causes a fluid path in the second tubular member to be communicated with the sealing ring setting space (39) via the communication hole (84) and via a gap between the seal ring setting surface (38) and the outer peripheral surface of the forward end portion of the second tubular member.

Abstract: A valve holding member made of a sheet metal includes a hub part (33) having a guide hole (34) through which a valve stem (23) and a plurality of arm parts (32) formed at the peripheral edge of the hub part. The arm parts are extend from the peripheral edge in an axial direction and in a radially outward direction with respect to the axis of the valve stem. The valve holding member also includes any one of a first reinforcing protrusion (35) formed in at least one of the arm parts which extends along a longitudinal direction of the at least one arm part and protrudes radially outward or inward with respect to the axis of the valve stem, a tubular reinforcing part (35c, 35e) formed around the guide hole and extending from the hub part in the axial direction, and a second reinforcing protrusion (35b) formed in the hub part and protruding in the axial direction.

Abstract: A female coupling member of a pipe coupling is provided which has a fluid passage and a vale therein. The fluid passage is separated by the valve into a first-end side adapted to be connected to a conduit and a second-end side adapted to be connected to a male coupling member. The valve is moveable between an open position for permitting a fluid to flow between the first-end side and the second-end side, and a closed position for blocking the flow of fluid. The valve is provided with a purge flow path that allows the second end side of the fluid passage to communicate with the outside when the valve is in the closed position, and that blocks the communication between the fluid passage and the outside when the valve is in the open position. Thus, the present invention simplifies the purge mechanism of the female coupling member which releases the fluid pressure remaining within the fluid passage when the valve is in the closed position.

Abstract: An entry auxiliary apparatus includes: an authentication entry detection unit, an adequacy determination unit and an entry auxiliary unit. The authentication entry detection unit detects a first authentication server URL included in data of a web page displayed. The adequacy determination unit compares the first authentication server URL with a second authentication server URL included in login information indicating an input history of authentication information and a third authentication server URL included in a service group. The service group, which includes a group of authentication server URLs locating authentication servers that authenticate with an identical authentication information, is related to the login information. The adequacy determination unit relates the login information to an adequacy level depending on a result of the comparison. The entry auxiliary unit assists input of authentication information into the web page based on the login information and the adequacy level.
