    • A fluid pressure chamber is formed in a fuel injection valve, in which a piston connected to a nozzle needle is reciprocally disposed. The pressure chamber is supplied with fluid under pressure from a fluid pump through a check valve. The pressure chamber is also connected with an orifice. When a fuel is distributed from a fuel injection pump under pressure and supplied to the injection valve, the nozzle needle is lifted by the distributed fuel under pressure. When the nozzle needle is lifted, the fluid in the pressure chamber is compressed for causing a fluid pressure applied to the piston in a valve closing direction, whereby the starting of the fuel injection becomes gentle, decreasing combustion noises.
    • 在燃料喷射阀中形成流体压力室,其中连接到喷嘴针的活塞相互配置。 压力室在流体泵通过止回阀的压力下被供给流体。 压力室也与孔连接。 当燃料从燃料喷射泵在压力下分配并供给到喷射阀时,喷嘴针在压力下由分配的燃料提升。 当喷嘴针被提起时,压力室中的流体被压缩,以使得在关闭方向上施加到活塞的流体压力,由此燃料喷射的启动变得平缓,燃烧噪声降低。

    • A micropost microcavity device has a maximum field intensity at the center of a high-index spacer as well as a small mode volume. The device has an approximately half-wavelength thick low-index spacer [400] sandwiched between two quarter wave stacks [410, 420]. The low-index spacer has a high-index subspacer layer [470] positioned at its center. The subspacer layer has a thickness smaller than a quarter wavelength. As a result, the electric field intensity remains a maximum at the center of the spacer where the high-index subspacer is positioned. A quantum dot or other active region [480] may be embedded within the subspacer [470]. The microcavity devices provide, for example, single photon sources, single dot lasers, low-threshold quantum dot or quantum well lasers, or devices for strong coupling between a single quantum dot and the cavity field which can be used as components of photonic integrated circuits, quantum computers, quantum networks, or quantum cryptographic systems.

    • A fuel injection device has a two-way control valve driven by a two-position actuator. The control valve directly controls oil pressure in a back pressure chamber to control an injection operation of an injection nozzle. A two-position three-way flow passage switching valve operated by control pressure of the control valve selectively connects a control chamber of a pressure intensifier with a fuel supply passage leading to a pressure accumulator or a pressure release passage leading to a low-pressure system to indirectly control oil pressure in the control chamber. The flow passage switching valve starts a pressure intensifying operation in retard of the injection operation. When pressure is supplied to the control chamber, stoppage of the pressure intensification operation and returning operation of the pressure intensifier do not lag behind the injection operation.
    • 燃料喷射装置具有由两位置致动器驱动的双向控制阀。 控制阀直接控制背压室中的油压,以控制喷射喷嘴的喷射操作。 通过控制阀的控制压力操作的两位三通流路切换阀选择性地将增压器的控制室与通向压力蓄能器的通道或通向低压系统的压力释放通道 以间接控制控制室内的油压。 流路切换阀在喷射操作的延迟中开始压力增加动作。 当向控制室供给压力时,加压增压器的停止和增压器的返回动作不落后于喷射动作。
