摘要： A fuel pump is driven by a variable, constant current, control circuit. A pressure control valve disposed between the fuel pump and a fuel rail includes a downstream pressure control valve and a bypass valve bypassing the downstream pressure control valve. The downstream pressure control valve sets the fuel pressure in the fuel rail to a predetermined value by opening or closing a passage from a fuel pipe to the fuel rail. If the fuel pump discharge pressure is sufficiently increased, the bypass valve is opened when the upstream fuel pressure is larger than the downstream fuel pressure by at least a predetermined differential pressure. In this way, fuel is supplied to raise the fuel rail fuel pressure. Therefore, it is possible during other times to reduce the consumed electric power of the fuel pump and thus prolong its life.

摘要翻译： 燃油泵由可变恒定电流控制电路驱动。 设置在燃料泵和燃料导轨之间的压力控制阀包括下游压力控制阀和旁通下游压力控制阀的旁通阀。 下游压力控制阀通过打开或关闭从燃料管到燃料轨的通道将燃料轨中的燃料压力设定为预定值。 如果燃料泵排出压力充分增加，则当上游燃料压力大于下游燃料压力至少预定压差时，旁通阀打开。 以这种方式，供应燃料以提高燃料轨道的燃料压力。 因此，可以在其他时间降低燃料泵的消耗电力，延长其使用寿命。

摘要： The oscillation element according to the present invention includes a torsion bar mounted on a base, and an oscillating member having a light reflection surface for reflecting light from a light source, which is fixed on the torsion bar protruding from the base. The oscillating member oscillates about a longitudinal axis of the torsion bar with an elastic deformation of the torsion bar, thereby deflecting the light that reflects at the light reflection surface in a direction intersecting the longitudinal axis. The oscillating member has two plates that are joined together so as to sandwich the torsion bar. On joining surfaces of the plates are provided with grooves for receiving the torsion bar, respectively. The plates have a symmetrical shape that the longitudinal axis serves as the axis of symmetry.

摘要： In a magnetic connector acquiring connection with a mating connector by magnetic force, a base member has a particular surface to be faced to the mating connector upon connection. An electrode terminal is fixed to the base member and adapted to be electrically connected to the mating connector. The base member has a magnetic force generating portion having a plurality of magnetic poles for producing the magnetic force. N and the S poles of the magnetic poles are alternately arranged along the particular surface in a predetermined direction. Thus, the connector is properly positioned relative to the mating connector by the magnetic force.
