Abstract: A control device includes a first control substrate including a processor and a communication interface; and a second control substrate including a processor and a communication interface. The first control substrate and the second control substrate are connected through the communication interfaces. When occurrence of an error in data communication through the communication interfaces is detected, at least one of the processor of the first control substrate and the processor of the second control substrate performs the data communication using unused signal lines among signal lines provided in the communication interfaces.

Abstract: A communication apparatus includes: a setting unit that sets plural candidate points which are candidates of positions of a transmitter based on a position of one of plural receivers that receive radio waves from the transmitter; and a specifying unit that specifies a position of the transmitter from among the plural candidate points by using (i) strengths of the radio waves which one or more receivers including a receiver other than the one receiver receive from the transmitter and (ii) strengths of the radio waves which are inferred to be received by the one or more receivers from the transmitter when it is assumed that the transmitter exists at each of the plural candidate points.

Abstract: A deflector apparatus for a vehicle includes a fixed frame, a movable frame positioned at an upper side of the fixed frame and being rotatable between a raised position and a retracted position, a mesh member connected to the fixed frame and the movable frame and brought to a raised state and a retracted state, and a spring member. The spring member includes a sliding portion fitted to a guide groove formed at the movable frame and slidably making contact with the guide groove to transmit a biasing force of the spring member in a state where the movable frame is rotating. The spring member further includes an engagement portion engaging with the movable frame when the movable frame is in the raised position. The movable frame is configured to be maintained at the raised position by the engagement with the engagement portion of the spring member.

Abstract: A deflector apparatus for a vehicle including a fixed frame provided at the roof portion, a movable frame positioned at an upper side of the fixed frame and being rotatable between a raised position and a retracted position, a mesh member connected to the fixed frame and the movable frame and brought to a raised state and a retracted state by a rotation of the movable frame, the mesh member extending above a surface of the roof portion in the raised state, and a spring member biasing the movable frame to the raised position. The fixed frame includes a connecting portion connected to the mesh member and provided at an upper side of a drain portion that is formed along a front-inner periphery of the opening. The connecting portion is arranged to have a clearance relative to the drain portion.

Abstract: An opening and closing device for moving a movable member which includes a drive gear connected to a power source, a driven gear geared with the drive gear, an immovable portion supporting the drive gear and the driven gear, and a dynamic transmission mechanism connected to the driven gear so that the driven gear and the dynamic transmission mechanism rotate together as a unit. The dynamic transmission mechanism transmits a drive force of the power source from the driven gear to the movable member. A direction of a rotational force affecting the driven gear via the dynamic transmission mechanism in accordance with a state of the movable member fluctuates. The opening and closing device further includes a friction member located at least at one position between relatively movable facing surfaces of the immovable portion, the drive gear, the driven gear, and the dynamic power transmission mechanism.

Abstract: An outboard motor includes an engine holder, an engine which is disposed above the engine holder in a state of the outboard motor mounted to a hull and in which a crankshaft extends substantially perpendicularly, and an oil pan disposed below the engine holder. A drive shaft housing is disposed below the oil pan and is formed with an exhaust chamber and a water pump is driven by the drive shaft so as to pump up a cooling water. A cooling water passage is formed in the oil pan and the drive shaft housing to guide the cooling water pumped up by the water pump to the engine. A relief valve is disposed on the way of the cooling water passage so as to discharge the cooling water into the exhaust chamber.
