Abstract: The present technology relates to an information processing device and an information processing method that enable output of information using a more optimal output modal. Provided is an information processing device including a processing unit configured to perform processes of: acquiring apparatus information regarding an output modal for each electronic apparatus; selecting an electronic apparatus having an output modal that outputs information from among a plurality of electronic apparatuses on the basis of the acquired apparatus information; and outputting the information from an output modal of the selected electronic apparatus. The present technology can be applied to, for example, electronic apparatuses such as information apparatuses, video apparatuses, audio apparatuses, or household electrical appliances.

Abstract: A cylinder block includes: a plurality of cylinder bores including respective openings formed on a piston insertion end surface of the cylinder block, pistons being inserted in the respective cylinder bores and being configured to reciprocate and slide in the respective cylinder bores when the cylinder block rotates; and a cooling portion, wherein the cooling portion includes a plurality of cooling holes each formed between the adjacent cylinder bores and extending from the piston insertion end surface in an axial direction of the cylinder block.

Abstract: A cylinder block including plurality of piston chambers formed at intervals in circumferential direction; plurality of pistons fitted in respective piston chambers movable in expanding and contracting directions to reciprocate in the expanding and contracting directions; a valve plate in contact with the cylinder block rear end surface and including first and second ports communicating with piston chambers. A portion of each ports is close to a top dead center switching land formed between first and second ports as a portion having a narrow opening width in a rotation radial direction of the cylinder block. An auxiliary port is formed at the valve plate switching land. Auxiliary port pressure is maintained lower than pressure of a side port that is the first or second port. When the piston chamber lacks communication with the side port (first or second port), the piston chamber and auxiliary port communicate with each other.
