Abstract: A control terminal device includes a display, at least one processor, and a memory configured to store instructions, when executed by the at least one processor, cause the control terminal device to transmit command messages to the plurality of communication devices disposed in respective areas and connected via a network, and to display on the display an operation screen, a device selection screen for selecting any one of the plurality of communication devices, and area images indicating the areas in which the respective communication devices are disposed so as to serve as a selection operation section for selecting the respective communication devices.

Abstract: An air-cooled engine capable of enhancing detection precision of a temperature sensor includes a crankcase, a crankshaft, a fan case, and an engine cooling fan. The installation direction of the crankshaft defines the front and rear direction. The fan case is provided in a front part of the crankcase, and the engine cooling fan is accommodated in the fan case. The air-cooled engine includes a cooling wind passage, a wind passage terminal end wall, an oil splashing device, and a temperature sensor. The wind passage terminal end wall is provided in a rear end of the cooling wind passage, the oil splashing device is provided on the rear side of the wind passage terminal end wall and formed to splash engine oil in the crankcase onto the wind passage terminal end wall, and the temperature sensor is attached to a front part of the wind passage terminal end wall.

Abstract: A spark ignition engine capable of fixing an ignition coil case even in a small engine includes an intake manifold 9 attached to a cylinder head 1, a coil case attachment stay 10 attached to the intake manifold 9, a cylinder portion through hole 12 formed on a board 11 of the coil case attachment stay 10, and a coil case attaching portion 13 provided in an upper part of the board 11. A flexible cylinder portion is caused to penetrate through a cylinder portion through hole, a tongue piece 15 is caused to protrude from a coil case peripheral wall 14 of an ignition coil case 7. The tongue piece 15 is mounted on the coil case attaching portion 13 and the coil case peripheral wall 14 is caused to abut on an edge portion 16 of the coil case attaching portion 13.

Abstract: An air-cooled V-shaped engine comprises a throttle body (10) and a flow-dividing plate (9) arranged ahead of a central cooling-air passage (8). The flow-dividing plate (9) is provided in a fan case (5) at a position forwardly of the throttle body (10) and has a bottom-plate portion (14) disposed at a position lower than the throttle body (10). The flow-dividing plate (9) divides the cooling air generated by an air-blowing fan (7) toward left and right sides of the central cooling-air passage (8). In this air-cooled V-shaped engine, the fan case (5) has a ceiling wall a central portion (11) of which is positioned just above the bottom-plate portion (14) of the flow-dividing plate (9). The central portion (11) of the ceiling wall of the flow-dividing plate (9) is provided at a position higher than the throttle body (10) as well as the central side portions (12), (12) of the ceiling wall, led out of the central portion (11) in a left and right directions.

Abstract: An electronic keyboard musical instrument has a cabinet, in which a tone generating system is housed, and the cabinet offers a sloped top surface to assistant goods; while the player is composing a piece of music with the assistance of a personal computer system, by way of example, the player puts the computer keyboard on the sloped top surface, and manipulates the computer keyboard without taking unnatural attitude so that the player can continue the work for a long time.
