Abstract: An oil level detection apparatus having a float-type oil level detector (50) and a mode switching unit. The oil level detector emits a signal indicating that the oil level has dropped when a movable contact disposed on a float (54) makes contact with fixed contacts once the level of oil (Lu) has dropped to a lower limit level. The mode switching unit switches between one of two modes selected from a first mode for actuating the alarm and stopping the engine (10) in accordance with the level drop signal, and a second mode for actuating the alarm and continuing to operate the engine (10) in accordance with the level drop signal.

Abstract: The invention intends to downsize a general-purpose engine generator and make operability thereof easy. A backup battery (233) is provided for the generator (22). The battery supplies electricity to an electronic controlled device such as a fuel pump for starting the engine. When the engine (1) carries out a rating operation, electricity is supplied from the generator (22). When the engine speed in a low speed range, only a pump (15) is driven. When the engine speed is exceeds the low speed range, the pump (15) is stopped, and an injectors, (10) and (27) are driven to be prevented from lapping over each other. When the engine speed reaches a high-speed range, the pump (15) is again driven. Electricity consumption at a time of starting is restricted by driving the electronic controlled devices at different timings until the engine (1) operation becomes self-sustaining.

Abstract: An operating condition of an outboard motor 1 is detected by an ECU 3, and then, is transmitted to a remote monitoring apparatus 6 using a mobile phone 5. The condition data transmission is made by only access from the outboard motor 1 side, therefore, security can be secured. When confirming a failure based on the condition data, the remote monitoring apparatus 6 decides the cause of failure by troubleshooting, and then, give information about measures to a boat 2 equipped with the outboard motor 1. Troubleshooting is carried out by acquiring a program from a server of maker, and the cause of failure is transmitted to the server so as to be stored as user information. The remote monitoring apparatus 6 orders necessary maintenance parts so as to improve quickness of maintenance.

Abstract: In an ignition coil for an internal combustion engine, the primary coil and the secondary coil of the coil unit are fabricated of self-welding wire and fixed in a coil case by an elastic material and an ignition control circuit unit is fixed in the coil case by an elastic material. Similarly, the primary coil and the secondary coil are integrally joined by an adhesive. The terminal of the primary coil and the lead of the ignition control circuit unit are joined together by fusion and the joint is partially molded, while the terminal of the secondary coil and the terminal of a high-tension cord outlet are joined together by fusing and the joint is partially molded. Moreover, the coil case is provided with an inner cap such that the fusing and partial molding of the terminals can be conducted on the inner cap, thereby ensuring a high recycle rate and enabling efficient resource recovery and reuse.

Abstract: A motor with a gear reducer includes a housing, a stator secured to the housing and having an inner periphery thereof defining a central space therein, and a rotor formed of a magnet material and rotatably fitted in the central space of the stator. The rotor has an axial through hole formed therein in coaxial relation to an axis of rotation of the rotor. An output shaft is connected through a gear reducer to the rotor to be rotatively driven thereby, for outputting a rotating output from the rotor through the gear reducer. The output shaft extends through the axial through hole of the rotor and is rotatably supported by opposite ends of the housing. The rotor has a gear forming part of the gear reducer formed thereon at one end thereof, and a hook formed thereon at another end thereof and engageable with a moving device such as an assembly jig in an axial direction of the output shaft.

Abstract: An electric wheel motor mounted integrally in a wheel has at least one electric leader line extending from the inside of a motor main body of the motor to the outside thereof. A breather passage is provided in the at least one electric leader line and communicates the inside of the motor main body with the outside thereof.

Abstract: A wheel motor for a vehicle is provided in which an electric motor is arranged in a central space defined in a wheel, to rotatably drive the wheel. A gear reducer is also arranged in the central space of the wheel, which has a plurality of gears including a final stage gear having an axial through hole formed therein. The electric motor includes a housing fixed to the vehicle body, a stator secured to the housing, a rotor rotatably fitted in a central space defined in the stator to generate the rotative driving force during rotation thereof, and an output shaft connected to the rotor through the gear reducer as well as to the wheel to be rotatively driven by the rotor, for transmitting the rotating output from the rotor through the gear reducer to the wheel. The output shaft extends through an axial through hole formed in the final stage gear of the gear reducer and an axial through hole formed in the rotor, and is rotatably supported by opposite end portions of the housing.

Abstract: An operation controlling apparatus for a passenger operated machine such as a tractor, snowmobile or the like. The apparatus includes an engine cut-off mechanism which terminates engine operation if an operator is expelled from the machine seat for a pre-determined time. Relatively short, intermittent periods of displacement of an operator from the seat, such as when travelling over rough or bumpy terrain, will not terminate engine operation. After emergency engine stoppage, the apparatus requires the machine be placed in a start waiting state, for instance by disengaging the clutch or when the transmission is placed in neutral, before the engine can be re-started.
