Abstract: A parallel hybrid electric vehicle includes an engine and a motor/generator as a rotary driving source. A differential device has a first shaft connected to the engine, a second shaft connected to the motor/generator, and a third shaft connected to a transmission device. The first and the second shafts can be coupled by a direct clutch. At the time of start of the vehicle with the engine in an idling condition, the motor/generator is controlled to enter a reverse rotation power generating condition, and the engine speed is maintained near an idling speed. After the start of the vehicle, when the motor/generator is in a forward rotation condition, the motor/generator is controlled to operate as a motor to maintain the engine speed at a target speed, and when the engine speed and the motor/generator speed coincide with each other, the direct clutch is made to enter a coupled condition thereby to prevent the occurrence of coupling shock, and also to reduce a driving time of the motor/generator.

Abstract: A system and controller for providing emergency power to an electrical load when a usual source of power for the load has failed, includes an electrical dynamo, an engine of controllable speed connectable by clutch to drive by a fixed speed ratio the dynamo, a continuously spinning flywheel to provide power while the engine is coming up to speed and during transient loads thereafter, and a control system. The flywheel is also connected with the dynamo, through a variable-speed transmission. When the engine is driving the dynamo, the speed of the engine is controlled by a loop, which involves sensing the torque of the flywheel, comparing the flywheel's speed with a first reference, and adjusting the throttle according to the difference.

Abstract: A starter for a natural energy powered motor comprises, an electricity storage means connectable to be charged with electrical energy from a natural energy source, a voltage conversion means are provided to step up the charging voltage to the electricity storage means. An energy level sensor means is connected to the electricity storage means to sense a predetermined maximum charging level and to thereupon in use trigger discharge from the storage means of sufficient electrical energy to start to motor to be driven by electricity from the natural energy source in use.

Abstract: A controller operates to start an electric power generator, for example a gasoline engine electric power generator, when a demand is made for electric power when the user turns on an electric powered device, such as a circular saw, that is to be used. The generator runs as long as there is a demand for power, and when the demand ends, the generator stops after a predetermined adjustable delay period. Additionally, in the event the engine is to be started under cold start-up conditions, the starter is operated to avoid cyclical starting/stalling of the generator engine. When a demand is made on the generator for power, the controller senses a circuit closure, turns on the starter of the generator, and, after the generator cranks, the power is applied to the saw and it starts to operate. The starter is controllably disabled after the generator is operational. The engine driving the generator will stop after a predetermined delay after the power demand is removed.

Abstract: A power system for providing an uninterrupitible power supply comprising a first generator connected to a primary external load, a second generator connected to a secondary external load, and a prime mover connected to said first and second generators by a common shaft. The first generator is electrically isolated from the secondary external load. The prime mover is an internal combustion engine that supplies rotational movement to the common shaft. The secondary external load is an electrical utility. A thermal recovery system is connected to the internal combustion engine.

Abstract: An engine of a motor vehicle is automatically stopped under predetermined conditions and automatically restarted under other predetermined conditions. The engine is restarted by a starter which is driven in response to an engine start signal. In automatically restarting the engine, the engine start signal is generated when restart conditions are fulfilled and a starter command is generated in a microcomputer. An operation of a clutch pedal is one of the restart conditions. The clutch pedal is provided therearound with a lower switch and an upper switch to detect an amount of a depression of the clutch pedal. The starter command is masked for a predetermined period of time starting from the time when the upper switch is turned OFF from the upper switch has been ON.

Abstract: An engine automatic control system for vehicles is adapted to automatically stop the engine when the vehicle motion is arrested, to automatically start the engine in response to operation of a starting mechanism for effecting start of the vehicle, and to maintain the engine rotation after start of the vehicle in dependence upon change of the level of speed pulses from a speed sensor assembly. The control system is arranged to be ineffective in its function for automatic stop of the engine when the speed sensor assembly is inoperative to maintain the engine rotation under the operative condition of the control system.

Abstract: An automatic control system for such a prime mover as a vehicle engine is adapted to automatically stop the prime mover when such a driven device as a vehicle is arrested, to automatically drive the prime mover in response to operation of a starting mechanism for effecting start of the driven device, and to maintain the prime mover in its operative condition when the driven device is moving. The control system is arranged to be inoperative in an expected occurrence of an error in operation of a setting switch for the system and to indicate the operative condition of the system under normal control of the setting switch.

The conditions of automatically stopping the engine includes at least a stopped state of a wiper which is driven by two-speed typed motor. Operating condition of the motor for driving the wiper is detected by a signal from either a low terminal or a high terminal of the motor.

Abstract: Apparatus for providing power to run essential machinery ordinarily run by an electrical main powered motor has a stand-by engine coupled by automatic clutch to the machinery to be driven. A compressed air system is fed by an electric motor driven compressor deriving its power from the electric supply main and by the stand-by engine driven compressor during periods of power failure. This system holding compressed air in reserve in a storage tank is used for powering a pneumatic motor to start the engine upon failure of power in the electric supply main. The supply of compressed air to the starter motor and to operate an engine operation switch is controlled by a power failure detector system also air operated which normally withholds compressed air from the pneumatic starter motor, but upon failure allows passage of the air to the starter motor.
