    • A semiconductor laser device of the invention is provided with: a supporting substrate, on the surface of which there is formed a wiring pattern; a LD that is fixed on the surface of the supporting substrate and that has a signal output section that emits signal laser light and a monitoring output section that emits monitoring laser light; and a monitoring PD. The monitoring PD has: a semiconductor substrate having a region that transmits light of the wavelength of the monitoring laser light; and a light receiving section for photoelectric conversion formed on the surface of the semiconductor substrate, one incident surface of the side surfaces of the semiconductor substrate being arranged in a position to which the monitoring laser light can be made incident, the light receiving section being arranged in a position higher than the monitoring output section, and a back surface of the semiconductor substrate and the wiring pattern being fixed on the supporting substrate so as to oppose to each other.

    • A brake fluid pressure control apparatus includes a second pump communicating port disposed to face a first pump communicating port approximately perpendicularly to the direction of movement of a spool. The first and second pump communicating ports are connected to a master cylinder, and a check valve is provided between the master cylinder and the first and second pump communicating ports. The check valve is adapted to open when the master cylinder-side brake fluid pressure becomes a predetermined value higher than the pump discharge-side brake fluid pressure. A master cylinder communicating port is provided to extend along the direction of movement of the spool. A cut-off valve is provided between the master cylinder communicating port and the master cylinder. The cut-off valve is closed when the spool is moved to provide communication between the pump communicating ports and a wheel cylinder communicating port.
    • 一种制动液压控制装置包括:第二泵连通口,设置成与阀芯的运动方向近似垂直的第一泵连通口。 第一和第二泵连通口连接到主缸,并且止回阀设置在主缸和第一和第二泵连通口之间。 当主缸侧制动器流体压力变得高于泵排出侧制动液压力的预定值时,止回阀适于打开。 主缸连通口设置成沿着阀芯的移动方向延伸。 在主缸连通口和主缸之间设有截止阀。 当阀芯移动时,截止阀关闭,以提供泵连通口和轮缸连通口之间的连通。
