    • A measuring apparatus is provided in one of two objects moving relatively to each other. The apparatus includes a circuit for effecting a direct spread modulation with respect to a transmission carrier signal using modulation codes; an antenna unit for transmitting the modulated carrier signal toward the other of the two objects and for receiving a reflection wave therefrom; a circuit for demodulating the received reflection wave signal using the transmission carrier signal; a circuit for making correlation between the demodulated output signal and a signal having the same code as that of the modulation code and having a phase delayed by a predetermined time; a unit for extracting a Doppler frequency component contained in a signal which has been propagated through a propagation path existing in a specified distance range; and a circuit for properly processing the extracted Doppler frequency component. By the constitution, it is possible to precisely measure a speed and/or direction angle of one object relative to the other of the two objects, without being subject to an influence by a reflection in the close neighborhood, or an influence by interference of a transmission signal or interference signal in a receiving channel of the apparatus.

    • A conventional automated analyzer has a mechanism for performing a stirring operation and a mechanism for performing a pipetting operation. The mechanisms are independent of each other. The time interval between the stirring operation and the pipetting operation is at least several seconds. A solid particle starts to settle out at the time of termination of the stirring operation. In the pipetting operation, an operation for suctioning a liquid is performed during a transient period of the process in which the solid particle settles out. The suction of the liquid containing a solid particle during the transition period of the process may cause a variation in the number of solid particles contained in the liquid pipetted. The problem is solved by means for simultaneously performing an operation for stirring a liquid reagent containing a solid particle and an operation for maintaining the reagent.
    • 传统的自动分析仪具有进行搅拌操作的机构和进行移液操作的机构。 这些机制是相互独立的。 搅拌操作和吸液操作之间的时间间隔至少为几秒。 在搅拌操作结束时,固体颗粒开始沉淀。 在移液操作中,在固体颗粒沉降的过程的过渡期间进行抽吸液体的操作。 在该过程的过渡期间,含有固体颗粒的液体的抽吸可能导致移液液中所含的固体颗粒数量的变化。 通过同时进行搅拌含有固体颗粒的液体试剂的操作和维持试剂的操作的方法解决了该问题。
