    • The code division multiplex transmission system according to the present invention produces data for transmission by, time-division multiplexing the signals for synchronizing spread code prepared for an easy synchronization of spread code on the receiving side and the information related to the structure or synchronization of each of a plurality of transmission data streams such as parameters information about the coding rate of the convolution code and interleaving size for each transmission data stream, generating spread frequency modulated signals of the above time-division multiplexed signals by a spread frequency modulation using a spread code known to the receiving side, and code-division multiplexing the resulting spread frequency modulated signals over the spread frequency modulated signals of the plurality of transmission data streams. As a result, the receiving terminal can obtain information such as parameters information of all the transmission data streams, as long as the receiving terminal receives the synchronization signal. Therefore, even if the receiving terminal does not understand the parameter values required for the reception of each transmission data stream, the receiving terminal can receive any transmission data stream easily and quickly, by setting the parameter values for each receiving process based on the parameters information about each transmission data stream obtained by the reception of the synchronization signal.

    • An energy-dispersive x-ray detector designed so that the space accommodating an x-ray detector device can be evacuated well and efficiently. When the detector device is not in use, a control portion stops the operation of a compressor and the operation of a refrigerator. Then, the temperature of an adsorbent rises. Gas which has been once adsorbed is released into the space, thus deteriorating the degree of vacuum. If the x-ray detector is instructed to operate via a console portion, the control portion operates a vacuum pump and opens an exhaust valve to evacuate the inside of the space. When the output signal from a vacuum gauge indicates that the degree of vacuum inside the space has reached a given level, the control portion closes the exhaust valve, stops the operation of the vacuum pump, and starts the operation of the compressor. As a result, the adsorbent is cooled. Then, the inside of the space is maintained at a desired degree of vacuum.
    • 设计成能够容纳X射线检测器装置的空间的能量分散型X射线检测器能够被良好且有效地抽真空。 当检测器装置不使用时,控制部分停止压缩机的操作和冰箱的操作。 然后,吸附剂的温度上升。 曾被吸附的气体被释放到空间中,从而使真空度恶化。 如果指示x射线检测器通过控制台部分操作,则控制部分操作真空泵并打开排气阀以抽空空间的内部。 当来自真空计的输出信号表示空间内的真空度达到给定水平时,控制部分关闭排气阀,停止真空泵的运转并开始压缩机的运行。 结果,吸附剂被冷却。 然后,将空间的内部保持在期望的真空度。

    • There is disclosed an electron microscope having an X-ray detector that detects the X-rays emanating from a specimen placed between the upper and lower magnetic pole pieces of an objective lens in the path of an electron beam. The dimension of the detector taken longitudinally of the gap between the pole pieces is larger than the dimension of the detector taken across the gap. A heat transfer rod is inserted between the gap to cool the detector. The detector is mounted to the rod. There is also disclosed an electron microscope having an X-ray detector mounted on the side surface of a heat transfer rod which faces the path of an electron beam. The rod extends along a straight line that runs substantially perpendicular to the path remotely from the path.

    • A packet-transmitting system comprising a transmitter and a receiver. In the transmitter, the packet-allocating circuit receives a stream of packets. The circuit allocates the packets having PIDs a1 to b1 to the transmission channel #1, the packets having PIDs a2 to b2 to the transmission channel #2, and so forth. The circuit allocates the packets having PIDs aN to bN to the last transmission channel #N. The control-data generating circuit time-divides and multiplexes packet-group data (groups of PIDs) representing the groups of packets to be transmitted via the channels #1 to #N, thereby generating control data to be transmitted through the transmission channel #0. The packets in the channels #0 to #N are multiplexed by a CDM system. In the receiver, the groups of packets, transmitted via the channels #1 to “N, are recognized from the control data transmitted via the channel #0, and only the signals transmitted via the channel designated by a user are extracted and reproduced. Thus, the receiver can therefore receive only the packet the user desires.

    • An electron microscope capable of performing accurate X-ray analysis. A specimen stage on which a specimen to be investigated is placed, is disposed between the upper and lower magnetic pole pieces of the objective lens. The specimen is irradiated with the electron beam to detect X-rays emitted from the specimen. The specimen stage consists of a light element, such as beryllium, that produces a very small amount of X-rays when irradiated with the electron beam. A metal film of a heavy element, such as gold, is deposited on the upper surface of the specimen stage. This metal film produces a large amount of X-rays when irradiated with the electron beam. The X-rays emitted from the lower magnetic pole piece are absorbed by the metal film. Consequently, the X-ray detector of the microscope detects only the X-rays produced from the specimen.
    • 能够进行精确X射线分析的电子显微镜。 放置试样的样品台设置在物镜的上下磁极片之间。 用电子束照射样品以检测从样品发射的X射线。 样品台由诸如铍的轻元素组成,当用电子束照射时产生非常少量的X射线。 重金属的金属膜,例如金,沉积在样品台的上表面上。 当用电子束照射时,该金属膜产生大量的X射线。 从下磁极片发射的X射线被金属膜吸收。 因此,显微镜的X射线检测器仅检测从样品产生的X射线。
