摘要： RC-network components that include a substrate and capacitor having a thin-film top electrode portion at a surface on one side of the substrate. The low ohmic semiconductor substrate is doped to contribute 5% or less to the resistance of the RC-network component. The resistance provided in series with the capacitor is controlled by providing a contact plate, spaced from the thin-film top electrode portion by an insulating layer, and a set of one or more bridging contacts passing through openings in the insulating layer. The bridging contacts electrically interconnect the thin-film top electrode portion and the contact plate. Different resistance values can be set by appropriate selection of the number of bridging contacts. The openings are elongated thereby reducing temperature concentration at their periphery. Correspondingly, the bridging contacts have an elongated cross-sectional shape.

摘要： By driving a fuel pump suitably to an amount of fuel according to an amount of fuel consumed by an engine and by monitoring an actual motor speed of the fuel pump, F/B control is carried out according to a target motor speed and the actual motor speed of the fuel pump. Meanwhile, by learning and storing a duty value comparable to a deviation between the target and actual motor speeds, duty driving of the fuel pump is corrected to suit an engine condition. It thus becomes possible to provide a fuel pump control apparatus of an engine capable of promoting power saving by suppressing a wasteful energy loss including a current consumption and making an internal circuit of an ECU simpler by enhancing fuel supply accuracy.

摘要： To improve a restart failure during fuel vapor occurrence, in a fuel injection control apparatus for an engine that is not equipped with a battery and starts the engine by a manual operation, the fuel injection control apparatus for an engine includes: an injector that supplies fuel to the engine based on pressure of the fuel supplied by a fuel pump; a power generating section for generating power based on rotation driving of a crank shaft of the engine; a starting device for manually starting the engine; and a control section for starting with power generation voltage by the power generating section and calculating a fuel injection amount based on an operation state of the engine. The control section includes: an injection amount calculating function unit that calculates, according to the operation state of the engine, an injection amount of the fuel to be supplied to the engine; an injection time conversion coefficient calculating function unit that calculates an injection time conversion coefficient for converting the injection amount into injector driving time based on a predicted fuel pressure value; and an injector driving time calculating function unit that calculates driving time of the injector based on an output of the injection amount calculating function unit and an output of the injection time conversion coefficient calculating function unit.
