Abstract: An exhaust system that reduces noise generated by exhaust gases is provided. The exhaust system includes a drive unit that supports an internal combustion engine. An exhaust guide forms an upper portion of the case. An oil pan is attached to a lower surface of the exhaust guide. An exhaust passage leads exhaust gas of the internal combustion engine from an upper side to a lower side of the case, and discharges the exhaust gas from the lower side into a body of water. A branch passage extends from the exhaust passage at an intermediate portion thereof. The branch passage is configured for discharging the exhaust gas inside the exhaust passage into ambient air, and includes an expansion chamber at its intermediate portion. The expansion chamber is partially defined by the exhaust guide and partially defined by the oil pan.

Abstract: A remote key entry system has a key unit and an answerback sound producing device. The key unit transmits a radio signal for remote-controlled locking and unlocking of a vehicle. The answerback sound producing device receives the key signal to indicate completion of correct locking or unlocking of the vehicle. The remote key entry system includes an environmental data sensing devices for obtaining data of an environment around the vehicle for control of the answerback sound. The system also has an answerback sound control device for controlling at least one of sound volume and tone of the answerback sound based on the environment data. The environmental data sensing device is an illumination sensing device for detecting environmental illuminance around the vehicle. The answerback sound control device varies the sound volume proportional to the illuminance.

Abstract: A break display apparatus for an intelligent power IC incorporating an overcurrent/overheating protection function. The break display apparatus includes a plurality of intelligent power ICs each incorporating an overcurrent/overheating protection function of detecting overcurrent/overheating for a load to break it, a pulse generating unit connected to the plurality of intelligent power ICs for generating a pulse signal having the number of pulses corresponding to a broken intelligent power IC as a signal for specifying the broken intelligent power IC on the basis of a break signal from the broken intelligent power IC, and a warning lamp for indicating the visual information of the broken intelligent power IC in response to the pulse signal generated by the pulse generating unit.

Abstract: An electrical wiring harness structure constituting a multiplex transmission network in a vehicle, in which a vehicle body is divided into a plurality of blocks, electrical components are mounted in units of blocks to constitute modules, and thereafter, the modules are combined to complete a vehicle body. The structure includes control nodes, arranged in units of modules, for controlling communications of the electrical components mounted on the corresponding modules, wiring harnesses, arranged between the adjacent modules, for forming a transmission path for performing communications among the control nodes, and connectors for connecting the wiring harnesses and the control nodes.
