    • 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.

    • In a transmitting system for a small-sized vehicle, a centrifugal clutch, and a torque converter including a pump impeller connected to an output drum of the centrifugal clutch and a turbine impeller connected to an output gear, are placed between a crankshaft of an engine and the output gear. The pump impeller and the output drum adjacent to the pump impeller are integrally coupled, with an open surface of the output drum facing to an opposite side to the pump impeller, to be constructed as a single component. Thus, occurrence of rotation vibrations and unusual noises can be prevented without requiring machining with high precision, and the numbers of components and assembling steps can be reduced while providing favorable maintainability.

    • A system and method for quantum key distribution uses a regulated single-photon source to sequentially generate a first photon and a second photon separated by a time interval Δt. The two photons are directed through a beam splitter that directs each photon to one of two transmission lines, which lead to two respective receivers. When one of the photons arrives at a receiver, it passes through an interferometer. One arm of the interferometer has a path length longer than the other arm by an amount equivalent to a photon time delay of Δt. The photon is then detected in one of three time slots by one of two single-photon detectors associated with each of the two interferometer outputs. Due to quantum-mechanical entanglement in phase and time between the two photons, the receivers can determine a secret quantum key bit value from their measurements of the time slots in which the photons arrived, or of the detectors where the photons arrived.
    • 用于量子密钥分配的系统和方法使用调节的单光子源来顺序地产生由时间间隔Deltat分离的第一光子和第二光子。 两个光子被引导通过分束器,其将每个光子引导到两个传输线中的一个,其导致两个相应的接收器。 当一个光子到达接收器时,它通过一个干涉仪。 干涉仪的一个臂具有比另一个臂长的路径长度等于Deltat的光子时间延迟的量。 然后通过与两个干涉仪输出中的每一个相关联的两个单光子检测器中的一个检测三个时隙之一中的光子。 由于两个光子之间的相位和时间的量子力学纠缠,接收器可以根据其光子到达的时隙或者光子到达的检测器的测量来确定秘密量子密钥位值。

    • A method of making released structures by using at least two directional etching steps. Cantilevers, bridges and many other structures can be made with the present invention. In a preferred embodiment, two directional etching steps are performed at opposing angles nonnormal to the substrate surface such that the substrate is undercut and a structure is released. Alternatively, more than two directional etching steps may be performed at various angles. For example, the substrate may be rotated continuously during the directional etching process. A cantilever formed by the method of the present invention necessarily has a substantially triangular cross section. Directional etching processes that can be used include focused ion beam etching and ECR plasma etching. Some directional etching processes may require the use of a patterned etch resist layer. Other etching processes such as focused ion beam etching may use scanning techniques to select which regions are etched. A backside etch can be performed to remove remaining substrate material under the released micromachined structure. The method is particularly well suited for making released cantilevers.
