Abstract: A hydraulic pump/motor includes: a cylinder block rotating about a rotation axis; a piston in a cylinder bore; and a valve plate facing a cylinder port. The valve plate includes: a high pressure port through which oil discharged from the cylinder port flows; a low pressure port through which the oil to be sucked into the cylinder port flows; a region disposed between the high and low pressure ports in a circumferential direction of the rotation axis and including a top dead center position facing the cylinder port of the cylinder bore in which the piston moved to a top dead center is disposed; and a residual pressure release port between the top dead center position and the low pressure port in the region. The residual pressure release port includes first and second ports disposed at positions different from each other in the radial direction of the rotation axis.

Abstract: A scan apparatus includes a scan unit configured to scan a document and generate image data, a reception unit configured to receive status information indicating a status of a user from a chat server, and a transmission unit configured to transmit the image data generated by the scan unit and information about a posting destination to the chat server, wherein the image data transmitted by the transmission unit is posted to the posting destination corresponding to the information transmitted by the transmission unit, wherein the transmission unit is configured to, while the status of a user corresponding to the posting destination is offline, not transmit the image data or the information, and wherein the transmission unit is configured to, if the reception unit receives status information indicating a responsive status of the user corresponding to the posting destination, transmit the image data and the information.

Abstract: A scanning apparatus includes a scanning unit configured to scan a document to generate image data, and a transmission unit configured to transmit, to a chat server, the image data generated by the scanning unit and identification information corresponding to a post selected as a post to which a reply is to be made. The image data transmitted by the transmission unit and the post corresponding to the identification information transmitted by the transmission unit are posted in association with each other to a talk room of a chat service provided by the chat server.

Abstract: A scanning apparatus includes a scanning unit configured to scan a document to generate image data, and a transmission unit configured to transmit to a chat server the image data generated by the scanning unit and a request to display information indicating that the image data is posted at a predetermined position on a screen in a talk room even if a message is posted to the talk room after the image data is posted to the talk room. The image data transmitted by the transmission unit is posted to the talk room, and the information indicating that the image data is posted is displayed at the predetermined position on the screen in the talk room.

Abstract: An information processing apparatus includes a first device, a second device, and one or more controllers that function as a first processing unit capable of controlling the first device, and a second processing unit capable of controlling the second device. The first processing unit receives information from the first device about a status of the first device and transmits a message to the second processing unit. The second processing unit receives the message from the first processing unit and controls the second device. In startup processes, the first and second processing units perform processes to start a communication with each other such that the first processing unit stores predetermined information in a predetermined storage area based on the information about the status of the first device received from the first device, and the second processing unit controls the second device based on the predetermined information acquired from the storage area.

Abstract: A communication I/F of an image generating unit writes settings for an image data to a transitory storage unit by serial communication before the image data is transmitted from the image generating unit to the transitory storage unit. The communication I/F stores partial information of an address used for previous writing in a cache unit, and omits the writing of the partial information of the address used for further writing if the partial information of the address matches the partial information of the stored address.

Abstract: A second processor verifies validity of at least a first boot program using a verification program, and a first processor executes a selection program to select a boot program verified as valid by the second processor, and executes the selected program.
