Abstract: A controller is configured to: perform a registration process for again storing connection information in an intermediary server; after the registration process, perform a transition process of changing a state of a device from a first state to a second state, the first state being a state where setting information is stored in a memory and a service is usable by the device, the second state being a state where intermediary server information is stored in the memory and the connection information and the setting information are not stored in the memory; after the transition process, receive, from the intermediary server, the connection information that is stored again; connect to a target server by using the received connection information and again receive the setting information from the target server; and store, in the memory, the setting information that is received again.

Abstract: In a riding-type mower, a vehicle body includes a rear portion in which a pair of right/left vehicle body frames extend in a front-rear direction relative to the vehicle body, with a gap therebetween in a lateral width direction. A mowing device is configured to discharge mown grass rearward relative to the vehicle body such that the mown grass falls onto the ground. A cover is provided in a bottom portion of the vehicle body, at a position that is rearward of the mowing device, and covers a gap between the pair of right/left vehicle body frames.

Abstract: To reduce the roughening of a surface of a workpiece whose hardness is increased by heat treatment. In a workpiece such as a guide plate (11), not a surface (11a1) of a groove (11a) that is a desired part for hardening (hardening target position) but a surface (11a2) opposite the surface (11a1) is heat-treated as a surface to be heated that is to be directly heated by an induction heating device. This can inhibit the surface (11a1) of the hardening target position from being roughened by the heat treatment and becoming lower in surface precision than before the heat treatment. Further, according to the present invention, the use of the induction heating device makes it possible to heat-treat only a necessary part.

Abstract: A lawn mower includes a pair of left and right main frames 17, an engine E mounted to the pair of left and right main frames 17, a radiator for cooling water that cools the engine E, a cooling fan 11 for feeding cooling air to the radiator, and a hood 9 accommodating the engine E, the radiator and the cooling fan 11. An air deflector plate 34 is provided between the pair of left and right main frames 17 and configured to change direction of cooling exhaust air flowing toward a ground surface.

Abstract: A work vehicle is provided with fuel supply lines that include a first fuel supply line that connects a first fuel tank and a junction. A second fuel supply line connects a second fuel tank and the junction. A common supply line connects the junction and a diesel engine. A fuel pump is provided on the common supply line. A first check valve is installed on the first fuel supply line and opens in accordance with a pressure differential between a pressure in the first fuel tank and a pressure in the junction. A second check valve is installed on the second fuel supply line and opens in accordance with a pressure differential between a pressure in the second fuel tank and a pressure in the junction. A fuel return line returns excess fuel from the diesel engine to the first fuel tank and the second fuel tank.

Abstract: A seat slide device includes lower rails and upper rails both formed substantially symmetrical bilaterally across a center in a width direction, and lock mechanisms on both sides of the upper rails to be engaged with the lower rails to lock them. An entire structure combining the lower rails, the upper rails and the lock mechanisms is substantially symmetrical forward, backward, and bilaterally, and a force applied to the lower rails and the upper rails can be absorbed substantially evenly forward, backward, and left and right. Since the lock mechanisms have an elastic lock member in a substantially center part in a longitudinal direction, the lower rails and the upper rails are elastically deformable for reduction of a biased load at a time of locking, improvement in vibration absorption characteristic, and the like, and a plate thickness of each material can be made thinner than conventional for weight reduction.

Abstract: In a work vehicle, a fuel supply path including a first fuel supply path connecting a first fuel tank to a merging portion, a second fuel supply path connecting a second fuel tank to the merging portion, and a common supply path connecting the merging portion to an engine is formed. A fuel pump supplying fuel to the engine is provided in the common supply path. Check valves that open according to a differential pressure between pressures on the fuel tank side and the merging portion side are interposed on the first fuel supply path and the second fuel supply path. A communication channel establishes communication between an upper space of the first fuel tank and an upper space of the second fuel tank is formed.

Abstract: A mower includes: a driver's seat provided to a vehicle frame. A transmission is arranged at least partially below the driver's seat. An engine arranged rearward of the transmission such that a bottom end of the engine is positioned higher than a bottom end of the transmission. An exhaust gas purification device is arranged rearward of the engine. An air cleaner is arranged forward of the exhaust gas purification device and above the engine. A radiator extends from an area between the transmission and the engine so as to project further upward than the air cleaner through an area between the driver's seat and the air cleaner.

Abstract: A work vehicle includes a fixed hood covering a rear area of an engine compartment housing an engine and an engine accessory, a swing axis extending through the rear area of the engine compartment in a transverse direction of the vehicle, and a swing hood swinging around the swing axis between a closed position and an open position. The swing hood tucks the fixed hood inside the swing hood and thus covers the fixed hood in the open position, and covers a front area and a middle area of the engine compartment and overlaps with a front end portion of the fixed hood in the closed position.

Abstract: A structural material is provided, the strength and toughness of which are well-balanced at a high level, suitable in particular for seat frames in automobiles, aircrafts and the like. Specifically disclosed is a structural material produced by integrally joining thin steel members in a part thereof and, after joining, thermally heating a part thereof so that the heat-treated part differs from the other parts in strength and toughness. Unlike a structural material, the strength of which as a whole has been uniformly improved by heat treatment, the above-described structural material consists of a part having a high strength and a part having low strength. Thus, a structural material, the strength and toughness of which are well-balanced at a high level can be obtained. Since the strength and toughness are well-balanced at a high level, the structural material is suitable particularly for seat frames in automobiles, aircrafts and the like.
