The electrical connection system includes a power source circuit for outputting a first voltage to operate a first load circuit. The power source circuit includes a conversion circuit for converting the first voltage into a second voltage lower than the first voltage. The system includes a second load circuit operative in response to the second voltage. The system includes a protection circuit for shunting the second load circuit with a threshold voltage between the first voltage and second voltage. The threshold voltage has identical influence on the second load circuit relative to the first voltage.

An engine includes a crank chamber in which pressure fluctuation occurs and a carburetor including a diaphragm fuel pump. The diaphragm fuel pump includes a pump chamber configured to suck in and eject fuel and a diaphragm chamber to which a pressure that drives the pump chamber is supplied. The diaphragm chamber and the crank chamber communicate with one another in a state in which a negative pressure is created in the crank chamber.

A lubrication apparatus for a four-stroke engine that prevents lubrication failure from occurring around the crankshaft and reliably prevents oil from remaining in a valve operating chamber includes: an intake part positioned below the level of an oil A in an oil reservoir even if the oil reservoir is tilted and the level of the oil A changes; an oil feeding passageway that sucks up the oil A from the intake part and supplies the oil A to the crank chamber; and an direct passageway that allows communication between a valve operating chamber and a crank chamber when a negative pressure is created in the crank chamber. Open end parts of the oil feeding passageway and the direct passageway which are open in the crank chamber are provided to open as the piston moves from a position near the top dead center to the top dead center.

A load drive (1) having a pulse converter (2) and a DC/DC converter (5). The pulse converter (2) is capable of converting a high DC voltage supplied from the power supply unit (10) of a vehicle to a pulse voltage and applies the pulse voltage to a first lamp (L1). The DC/DC converter (5) operates to convert the high DC voltage to a low DC voltage whose voltage value is lower than the voltage value of the high DC voltage and applies the low DC voltage to a second lamp (L2).

摘要:
When an ignition switch is off, even if a master CPU (20a) receives a predetermined command signal, the master CPU (20a) does not immediately transmit an activating signal to slave CPUs (20b). At this time, power necessary for an electronic control unit (8c) is being supplied from a standby-current supplying converter (10). The master CPU (20a) transmits an activating request signal to a controller (12) to activate a normal supplying converter (9). The controller (12), after activating the normal supplying converter (9), transmits an activating completion signal to the master CPU (20a). For the first time upon receipt of this activating completion signal, the master CPU (20a) transmits the activating signal to the slave CPUs (20b). Consequently, power is supplied from the normal supplying converter (9) to all the electronic control units (8c to 8f).
摘要:
A load driving apparatus is constituted with a high voltage power source, a low voltage power source, a first switching element, a second switching element, a lamp load, current detecting section, and PWM control section. The first switching element is connected to the high voltage power source which supplies a high voltage and is connected to the lamp load. The second switching element is connected to the low voltage power source which supplies a low voltage and is connected to the lamp load. The current detecting section detects a value of current flowing in the lamp load. The PWM control section is connected the first switching element, the second switching element, and the current detecting section to control a voltage to be supplied to the lamp load. The PWM control section turns the second switching element in ON state at first, and the low voltage is being supplied to the lamp load while the value of the current detected in the current detecting section is more than a predetermined value. Once the value of current detected by the current detected section becomes below the predetermined value, the PWM control section turns the second switching element in OFF state and drives the first switching element to supply the high voltage converted to a pulse voltage to the lamp load.

A brake control system includes at least a pair of brake systems respectively connected to a pair of brake operating members L1, L2, and a control unit 10 for controlling the brake forces of the pair of brake systems interlockingly according to a predetermined distribution ratio by operating one of the pair of brake operating members L1, L2. The control unit 10 executes a decreasing control on the brake forces in such a manner that, when releasing the pair of brake operating members L1, L2, the control unit 10 decreases both of the brake forces together, even in a state where the control unit performs the interlocking control so as to decrease the brake force of one of the brake system as the brake force of the other of the brake system is increased in accordance with the predetermined distribution ratio.
