摘要： A fuel tank lid includes a lid part closing an opening of a fuel tank, and an internal terminal electrically connecting a pump provided inside the fuel tank with a drive circuit driving the pump. The lid part includes an inserted part inserted into the opening, a storage part located outside the fuel tank and storing the drive circuit in a hollow space of the storage part, and a connection part located outside the fuel tank and connecting the inserted part and the storage part. The fuel tank lid further includes a discharge part discharging a fuel vapor that tries to travel along an interface between the internal terminal and the lid part and enter the hollow space, to an external atmosphere, and a protection part covering the portion exposed from the lid part by the presence of the discharge part to protect the portion from a liquid.

摘要： An injection control device controls a solenoid in a fuel injection valve. The injection control device includes a transistor on an upstream side of a first power supply path to the solenoid, and a transistor on an upstream side of a second power supply path to the solenoid. The injection control device has another transistor with a body diode arranged in parallel at a position between an upstream terminal of the solenoid and ground. The injection control device also includes a transistor on the downstream side of the first and second power supply paths. A drive controller in the injection control device drives the solenoid to an open position by switching ON the transistor on the downstream side and one of the transistors on the upstream side power supply paths.

摘要： A semiconductor package includes semiconductor elements, a lead frame, a crosslinked member, and sealing resin. Each of the semiconductor elements has a first surface and a second surface located on a side opposite to the first surface. The lead frame has a mounting portion and a connected portion. At least one of the semiconductor elements mounts on the mounting portion. The connected portion is separated from the mounting portion. The crosslinked member is connected to the second surface of at least one of the semiconductor elements and the connected portion to electrically connect at least one of the semiconductor elements and the connected portion. The sealing resin is electrically insulated and covers a portion of the lead frame, the semiconductor elements and the crosslinked member. At least one of the semiconductor elements is different from another one of the semiconductor elements in element size or power consumption.

摘要： An injection control device controls a solenoid in a fuel injection valve. The injection control device includes a transistor on an upstream side of a first power supply path to the solenoid and a transistor on an upstream side of a second power supply path to the solenoid. The injection control device has another transistor with a body diode arranged in parallel at a position on the first power supply path between the first transistor and an upstream terminal of the solenoid. The injection control device also includes a transistor on the downstream side of the first and second power supply paths. A drive controller in the injection control device drives the solenoid to an open position by switching ON the transistor on the downstream side and the transistor on the upstream side of the first power supply path or the transistor on the upstream side of the second power supply path.

摘要： An injection control device controls a drive of a solenoid in a high pressure pump for pressurizing fuel to an internal combustion engine. The injection control device includes a transistor on an upstream side of a power supply path from a direct current power supply line to the solenoid and a transistor provided on a downstream side of the power supply path. The injection control device further includes a diode at a position between an upstream terminal of the solenoid and ground, a transistor arranged in parallel with the diode, and a drive controller. The drive controller drives the solenoid to an open position by switching ON the transistors on the upstream and downstream sides of the power supply path.

摘要： A fuel tank lid includes a lid part and a terminal. The lid part includes an inserted part inserted into an opening of a fuel tank, and a storage part storing a drive circuit. The terminal has a central portion covered by the inserted part and the storage part, a first end connected to a pump, and a second end connected to the drive circuit. The storage part includes a side wall that has a first opening and a second opening, an upper closure part that closes the first opening, and a lower closure part that closes the second opening. The fuel tank lid further includes a discharge structure positioned vertically lower than the upper closure part and discharging a fuel vapor that has travelled along an interface between the terminal and the lid part and entered a hollow space of the storage part, to an external atmosphere.
