Abstract: A management device includes a processor configured to: when a coupling relationship between an own node and another node in which a channel capable of off-chain transaction is formed among a plurality of nodes capable of communicating with each other is registered, transmit first route information that represents the coupling relationship to a node in a first group that includes an own node and the another node among the plurality of nodes; and when second route information that represents a coupling relationship between a first node in the first group and a node in the first group is received from the first node that has received the first route information, update route table information used for a route search from an own node to a node serving as a payment destination in the first group based on the received second route information.

Abstract: A recording medium stores a communication program executed by communication devices and causing: a first computer of a first communication device, on a side of providing data, to register first metadata including the data and attribute information; a second computer of a second communication device, on a side of using the data, to register second metadata including a processing service when processing and using the data and attribute information; the first computer to determine whether or not to approve the processing service based on the first and second metadata; and when the determination of whether or not to approve is to approve, a third computer of a third communication device, on a side of processing the data, to execute data processing based on the processing service in a data processing environment that disapproves access from the first and second communication devices to the data and the processing service.

Abstract: A non-transitory computer-readable storage medium storing a management program that causes a processor included in a computer to execute a process, the process includes extracting data identification information that identifies monitoring target data from instruction log data, the instruction log data being recorded operation for the monitoring target data to be monitored, and storing, in a memory, the data identification information and history identification information that identifies history data in association with each other, the history data indicating a history of the operation for the monitoring target data.

Abstract: A linear member gripping device includes: a first gripping member that abuts a linear member; a second gripping member that abuts the linear member and has a protrusion; a first drive part and a second drive part that change relative positions of the first and second gripping members; and a limitation part that limits movement of the linear member sandwiched between the first and second gripping members at a predetermined limitation position.

Abstract: A non-transitory computer-readable recording medium having stored therein a program included in a communication apparatus that is configured to cause a computer to execute a procedure, the procedure includes when a first process related to first data is executed, arranging, in a pointer table included in a distribution ledger by which history related to distribution of data is managed in a data distribution system which includes the communication apparatus, pointer information which associates a source identifier which is an identifier of a history item of a process related to the first data performed before the first process is executed with a next identifier which is an identifier of a history item of the first process, and synchronizing content of the pointer table with content of a pointer table of another communication apparatus.

Abstract: A recording medium stores a communication program executed by communication devices and causing: a first computer of a first communication device, on a side of providing data, to register first metadata including the data and attribute information; a second computer of a second communication device, on a side of using the data, to register second metadata including a processing service when processing and using the data and attribute information; the first computer to determine whether or not to approve the processing service based on the first and second metadata; and when the determination of whether or not to approve is to approve, a third computer of a third communication device, on a side of processing the data, to execute data processing based on the processing service in a data processing environment that disapproves access from the first and second communication devices to the data and the processing service.

Abstract: A non-transitory computer-readable storage medium storing a program that causes a processor included in computer to execute a process, the process includes requesting a terminal of a purchaser who has purchased data to pay for the data and a deposit, transmitting the data to the terminal in response to the payment for the data and the deposit, and refunding an amount of money within the deposit to the terminal of the purchaser in response to a report on illegitimacy of a distributor of the data from the terminal of the purchaser.

Abstract: An information processing method executed by a processor included in a computer, the computer including a memory that stores a plurality of flow entries in each of which a packet condition for choosing a packet, a processing content corresponding to the packet, and a type of the processing content are associated with one another, the information processing method includes choosing, from the flow entries, one or more candidate flow entries respectively including a type different from the type included in a new flow entry, when storing the new flow entry; detecting, from among the one or more candidate flow entries, a competitive flow entry having the processing content different from that of the new flow entry based on the packet condition; and notifying another information processing device coupled to the information processing device of a result of the detecting.

Abstract: A return mechanism is achieved which requires only a small force for operation. In one aspect of the present invention, a return mechanism (10) includes: a first spring (1) that acts between an operating section (11) and a working section (12); and a second spring (2) that acts between the operating section (11) and a base (13). A direction in which the second spring acts when the operating section (11) is in a first position is not parallel to a direction in which the second spring (2) acts when the operating section (11) is in a second position. A component which, of a force of the second spring, acts in a direction of motion of the operating section (11) is smaller when the operating section (11) is in the second position than in the first position.

Abstract: A power generation device including a rotation member rotatable by an operation force and a supporting member supporting the rotation member by attracting the rotation member with a magnetic force, the power generation device inducing a current to a coil by a magnetic flux of a magnet caused by rotation of the rotation member, and where, when the operation force is applied in a first state in which the rotation member is supported by the supporting member by being attracted to a first and second portions of the supporting member at respective first and second positions, the rotation member transitions to a second state by rotating with the first position of the supporting member as a first supporting point, and further transitions to a third state by rotating with a position of the supporting member different from the first position as a second supporting point.
