  • Publication number: 20260194157
    Abstract: An electric valve includes a valve body that has a valve port and a valve seat enclosing the valve port, a valve member that faces the valve port, a valve stem, and a stepping motor. The valve stem has an external thread. The valve body has an internal thread into which the external thread is screwed. The external thread and the internal thread constitute a screw-feed mechanism. The valve stem is coaxially secured to a magnet rotor of the stepping motor. The lower end of the valve stem is connected to the valve member. When the magnet rotor rotates in a valve closing direction, the valve member moves toward the valve port. When the valve member comes into contact with the valve seat, the valve member is restricted from moving toward the valve port.

  • Patent number: 12545037
    Abstract: A printing apparatus includes a divider disposed downstream of a print engine in a conveyance direction, and a controller. The controller causes a conveyor to convey a print medium until a planned dividing position of the print medium reaches a dividing position of the divider, when a first conveyance amount is larger than a second conveyance amount. The first conveyance amount corresponds to a print width for a printing process by the print engine. The second conveyance amount is calculated using a distance between a reference position and the dividing position and a distance between the reference position and the planned dividing position. After the planned dividing position of the print medium reaches the dividing position, the controller causes the divider to divide the print medium into first and second print media. The controller causes the conveyor to convey the second sheet to a printing position.

  • Publication number: 20250378269
    Abstract: A contract management system acquires application information, which is information obtained from an applicant applying for the execution of a contract, written in natural language, and extracts contract event information, which is information related to a contract event, which is an event that causes the execution of the contract, from the contract written in natural language. The contract management system inputs the application information and the contract event information extracted from the contract into a large language model to determine whether the application information includes a contract event. If the application information includes a contract event, the contract management system acquires contract execution information, which is information necessary for the execution of the contract corresponding to the contract event, by inputting the application information into the large language model, and inputs the acquired contract execution information into the contract execution system.

  • Publication number: 20250307801
    Abstract: In an information processing system that provides a function for issuing or verifying a verifiable credential and a verifiable presentation, which is implemented between a plurality of organizations by a self-sovereign identity (SSI) technology, a creation request of extraction information specifying storage or non-storage, for information in the verifiable credential, in a blockchain (BC) of a distributed ledger system is received from a node, an approval or non-approval of information specifying storage or non-storage in creation request information generated based on the creation request is determined by consensus formation in the distributed ledger system, and the extraction information is created based on the creation request information when consensus is reached. BC storage information to be stored in a distributed ledger is created based on a schema or a credential definition and the extraction information.

  • Publication number: 20250198534
    Abstract: An electric valve includes a valve member that includes a control portion having a single tapered shape. A stepping motor rotates to move the valve member in a moving section between a valve closing position and a full-open position. When the valve member is at the valve closing position, a control surface of the control portion is in contact with a valve seat. When the valve member moves from the valve closing position and is in the moving section, a throttle passage is formed between the valve seat and the control surface. The moving section includes a first section between the valve closing position and a first position and a second section between the first position and a second position. A controller sets a step angle when the valve member is in the first section to be smaller than when the valve member is in the second section.
