    摘要： In a wireless communication system, the communicating stations reduce their transmitting power level when they detect interference exceeding a certain level. Interference is detected by down-shifting the received signal to place the desired signal in the baseband, then sampling the down-shifted signal, first at a sampling frequency high enough to catch the interference, then at a lower sampling frequency that excludes the interference. This system is useful for vehicle-to-vehicle communication in an environment in which vehicle-to-roadside communication may also be present at various nearby frequencies, because it does not require exact knowledge of the interfering frequencies and allows communication to continue even when interference is present.

    摘要： In electron holography observation using a transmission electron microscope, searching of conditions of an electron optical condition which are necessary for realizing a requested spatial resolution is sophisticated and for persons unaccustomed to operation of the electron microscope, the observation is time consuming work. In addition to the fundamental electron microscope proper, an input unit for inputting a spatial resolution requested in the holography observation, a calculation unit for calculating positions of electron biprism and specimen necessary for realizing the requested spatial resolution from the inputted value and parameters characteristic of the device and mechanisms for moving the two positions for realizing the obtained calculation results are provided.

    摘要： The present invention provides a compact electron lens causing little aberration, and a charged particle beam apparatus such as a scanning electron microscope that is super compact and offers a high resolution. An upper magnetic pole and a sample-side magnetic pole are magnetically coupled to the respective poles of a permanent magnet that is made of a highly strong magnetic material such as a rare-earth cobalt system or a neodymium-iron-boron system, that is axially symmetrical, and that has a hole in the center thereof. An inner gap is created on the side of a center axis. Thus, a magnetic lens is formed axially. Moreover, a semi-stationary magnetic path that shields an outside magnetic field and has the magnetic reluctance thereof regulated is disposed outside. The sample-side magnetic pole and magnetic path defines a region where magnetic reluctance is the highest outside the permanent magnet. A space defined by the permanent magnet, upper magnetic pole, sample-die magnetic pole, and semi-stationary magnetic path is filled with a filling made of a non-magnetic material. Thus, an objective lens is constructed.

    摘要： A dual-stream filling valve is used in a flowable material filling apparatus to introducing at least two flowable materials into a container. The dual-stream filling valve defines a material flow path therethrough. The valve includes a primary filling tube having an inlet end and a discharge end and defining a primary filling tube internal flow region. The primary filling tube defines a first opening therein intermediate the inlet and discharge ends. A secondary filling tube has an inlet end and a discharge end and defines a secondary filling tube internal flow region. The secondary filling tube is positioned at least in part within the primary filling tube internal flow region, penetrating the primary filling tube through the first opening. The dual-stream valve includes a valve plug that includes a portion that is movable relative to the secondary filling tube between an opened state wherein flow communication is established between the internal flow regions of the primary and secondary filling tubes and a closed state wherein flow communication is terminated between the internal flow regions of the primary and secondary filling tubes. An actuator is provided for moving the valve plug portion between the opened and closed positions. The actuator is disposed fully external of the secondary filling tube flow region.
