    Abstract: An imaging apparatus includes a first electrode, a second electrode, a photoelectric conversion layer, a charge injection layer, and a charge accumulation region. The second electrode opposes the first electrode. The photoelectric conversion layer is located between the first electrode and the second electrode, contains a donor semiconductor material and an acceptor semiconductor material, and generates a pair of an electron and a hole. The charge injection layer is located between the first electrode and the photoelectric conversion layer. The charge accumulation region is electrically coupled to the second electrode and accumulates the hole. An ionization potential of the charge injection layer is less than or equal to an ionization potential of the acceptor semiconductor material. Electron affinity of the charge injection layer is less than or equal to electron affinity of the acceptor semiconductor material. Light transmittance of the charge injection layer is greater than or equal to 70%.

  • Patent number: 11920685
    Abstract: A valve device includes a rotation shaft, a valve body, and a biasing portion. The valve body is configured to be rotationally displaceable about the rotation shaft between a closed position and an open position. The biasing portion biases the valve body so as to cause the valve body to approach the closed position. The valve body includes an upstream wall arranged in a position upstream of the rotation shaft in a flow direction of the fluid when the valve body is in the closed position. The valve body includes a rotation end, which is an end distal from the rotation shaft and moves downstream in the flow direction of the fluid in response to a displacement of the valve body from the closed position to the open position, and the rotation end is shaped to project upstream when the valve body is in the closed position.

  • Patent number: 11870907
    Abstract: When a user attempts to execute a procedure for transfer or the like from an app, user authentication is first required by a PIN code or the like. When the user authentication is successful, function limitation of an IC chip is released and a mode in which a function provided by the IC chip can be used is set. The app encrypts a procedure message describing procedure content with a private key using the function of the IC chip and creates an electronic signature. When the electronic signature and the procedure message are sent to an online service server, the server verifies the electronic signature using the corresponding electronic certificate. When the procedure message is sent from a valid user and it is confirmed as a result of the verification that the content is not altered, the server executes the procedure for transfer or the like in accordance with the content of the procedure message.

  • Patent number: 11863681
    Abstract: When a user activates an app, user authentication by a PIN code or the like is first executed. When the user authentication is successful (that is, when it is confirmed that a party operating the app is a user), function limitation of the IC chip is released and a mode in which a function provided by the IC chip can be used is set. The app creates an electronic signature with a private key using the function of the IC chip. When the electronic signature and the user ID are sent to a server of an online service, the server verifies the electronic signature using the corresponding electronic certificate. When the user ID is confirmed to be a user ID sent from a valid user, the user is permitted to use the online service.

  • Patent number: 11820328
    Abstract: This vehicle anti-theft device comprises: a wireless receiver that is installed in a vehicle and receives information including the ID of a portable device transmitted wirelessly from the portable device; a first registration processing unit that registers a first ID received by the wireless receiver, using a predefined procedure, as the ID of the portable device belonging to an owner group; a second registration processing unit that, when a second ID is received by the wireless receiver together with the ID registered by the first registration processing unit, registers the second ID as the ID of the portable device belonging to an affiliate group; and a theft determination processing unit that, on detecting movement of the vehicle without having received the ID registered by the first registration processing unit or the ID registered by the second registration processing unit at that time, determines that the vehicle is in a stolen state.
