Abstract: An electronic device of the present disclosure includes: a first housing that includes a first outer surface including a keyboard and includes a second outer surface opposite to the first outer surface; a second housing that houses a display and is connected to the first housing; and a speaker unit disposed inside the first housing. The second outer surface includes a recess. A recess includes a through hole in at least a part of a surface of the recess. At least a part of the speaker unit faces at least a part of a back surface of the surface of the recess including the through hole.

Abstract: An electronic device includes a housing, a covering member that covers the housing, and an attachment part that detachably attaches the covering member to the housing. The attachment part includes a one-side attachment part and at least one other-side attachment part. The one-side attachment part includes a first projection of the covering member extending from a first member toward a second member, a first accommodation part of the housing that accommodates the first projection, and a first movement restriction part that restricts movement of the first projection. The other-side attachment part includes a protrusion of the covering member extending from a second member toward a third surface of the housing, a second projection extending from the protrusion in a direction away from the first member, a second accommodation part of the housing that accommodates the second projection, and a second movement restriction part that restricts movement of the second projection.

Abstract: An electronic device includes a first unit and a second unit including a display device. The first unit includes a housing, a blower device, and an exhaust path. The exhaust path includes a first member, a second member, a third member, and a partition member. The second member faces the second unit positioned at an opened position. The third member faces the first member and extends from an end of the second member far from the first member in a direction away from the first member as the third member is away from the second member. The partition member is disposed at an end close to the second member in a first direction and between the first member and the third member, and extends along the first direction. The second member includes a first exhaust hole. The third member includes a second exhaust hole larger than the first exhaust hole.

Abstract: An electronic device includes a first housing including a display, a second housing including an operation unit, and a rotation unit that rotates the first housing relative to the second housing. The second housing includes a rotation regulation portion that protrudes from a bottom face of the second housing and regulates rotation of the first housing. The rotation regulation portion includes an elastic member configured to rotate back and forth between a first mode and a second mode with different states of protrusion from a bottom face of the second housing, and contactable with the first housing. The rotation regulation portion, in the first mode, regulate rotation of the first housing in a first rotation range, and in the second mode, regulate rotation of the first housing in a second rotation range where the first housing is rotated to a greater extent than in the first rotation range.

Abstract: An electronic device of the present disclosure includes a body unit, and a keyboard unit disposed on the body unit. The keyboard unit includes a keyboard, a housing that has a frame shape and houses the keyboard, and a plurality of retainers connected to the housing to retain the keyboard. A plurality of retainers are formed of a material having a specific rigidity higher than that of the housing.

Abstract: A power regeneration system of a work vehicle includes: a first generator (12) and a second generator (31) that are driven by an engine (11); a first electric circuit (C1) for supplying electric power to traveling motors (10L, 10R); a second electric circuit (C2) for supplying electric power to an auxiliary device (35); a voltage step down converter (21) providing electric power from the first electric circuit to the second electric circuit; and a controller (51) that determines whether a travel mode of the work vehicle is a powering mode or a regeneration mode in order to control driving of the voltage step down converter. If the travel mode is the regeneration mode, the controller provides the regenerative power from the first electric circuit through the voltage step down converter to the second electric circuit, in order to drive the auxiliary device with the regenerative power.

Abstract: To provide a power regeneration system for a working vehicle that can effectively use a regenerative electric energy. A first electric circuit for supplying an electric power generated by the first generator to a traveling motor, a voltage detector for detecting an actual voltage of the first electric circuit, a second electric circuit for supplying an electric power generated by a second generator to an auxiliary device, a step-down device connected to the first electric circuit and the second electric circuit, and a controller are provided. The controller estimates the voltage of the first electric circuit after a predetermined time has elapsed from the present time, based on information on a traveling state of a work vehicle and the actual voltage detected by the voltage detector, and outputs a drive command to the step-down device when the estimated voltage is equal to or more than a threshold.

Abstract: An electronic apparatus includes: a first antenna board having a plate shape and extending with a first length; a second antenna board having a plate shape and extending with a second length; and a rectangular parallelepiped upper casing for accommodating the first antenna board and the second antenna board. The first antenna board and the second antenna board are arranged such that a longitudinal direction of the first antenna board and a longitudinal direction of the second antenna board are parallel to one side of one main surface of the rectangular parallelepiped upper casing. The first antenna board and the second antenna board are arranged parallel to each other.
