    Abstract: A powdery particle conveying system is provided in which electric power consumption can be saved when powdery particles are conveyed by use of a roots blower. In the case where the powdery particles are conveyed to a reservoir tank near the roots blower, the frequency of a power source of a roots blower driving motor is reduced, thereby reducing an output of the roots blower. In contrast, in the case where the powdery particles are conveyed to a remote reservoir tank, a voltage of a commercial frequency is applied to the motor.

    Abstract translation: 提供一种粉状颗粒输送系统，其中当粉末颗粒通过使用鼓风机输送时可以节省电力消耗。 在将粉状颗粒输送到靠近鼓风机的储罐的情况下，根鼓风机驱动马达的电源的频率降低，从而减少了根鼓风机的输出。 相反，在将粉状颗粒输送到远程储存罐的情况下，商用频率的电压被施加到电动机。

    Abstract: Provided are a fine particle production apparatus and a fine particle production method that can control the particle sizes of fine particles, and efficiently produce a large amount of fine particles having good particle size uniformity. The present invention comprises: a raw material supply unit which supplies raw materials for fine particle production into thermal plasma flame; a plasma torch in which the thermal plasma flame is generated, and which evaporates the raw material supplied by the raw material supply unit by means of the thermal plasma flame to form a mixture in a gas phase state; and a plasma generation unit which generates thermal plasma flame inside the plasma torch. The plasma generation unit includes: a first coil which surrounds the plasma torch, a second coil which is installed below the first coil in the longitudinal direction of the plasma torch and surrounds the circumference of the plasma torch; a first power supply unit which supplies an amplitude-modulated first high-frequency current to the first coil; and a second power supply unit which supplies an amplitude-modulated second high-frequency current to the second coil. The degree of modulation of the first high-frequency current is smaller than the degree of modulation of the second high-frequency current.

    Abstract: A highly-sensitive-allergen-measurement method is provided. A method for detecting an allergen in a sample comprises treating the sample with a protease, and detecting the presence or absence of an allergen-derived polypeptide in the enzymatically treated sample by a chromatographic separation analysis, wherein the allergen is one or more members selected from the group consisting of buckwheat, crustacean, milk, egg and peanut.
