    • Provided are a method and device for improving a response speed in a measurement of viscosity of a fluid and obtaining a continuous smooth measurement graph. A viscometer includes a machine part that generates a shear rate in a sample, a machine drive, a shear rate changing means that outputs a target shear rate of the machine part, and a displacement detection sensor that measures displacement of the machine part, and performs feedback control to control a driving force of the machine drive so that an output value of the displacement detection sensor corresponds to the target shear rate and measures a viscosity of a sample, wherein a feedback gain is simply set for each measurement according to an optimum design or target shear rate.

    • The effect of air flow on a weighing dish is minimized by the following relatively simple arrangement. A mounting member (1) having a protection dike (1D), an engaging ridge (1B), and a outermost peripheral engaging wall (1A) formed in a concentric manner about an opening (1C) to insert therethrough a connecting portion (2A) is disposed on an upper casing (3) of a weighing device located on a lower surface of a weighing dish (2). First and second windproof walls (4, 5) are positioned by fitting to an inner peripheral wall of the engaging ridge 1B and the engaging wall (1A), respectively, and can be easily removed when necessary, such as for cleaning. For example, the second windproof wall (5) is formed higher than the first windproof wall (4), thereby enabling effective obstruction of air flow from the outside.
    • 通过以下相对简单的布置,气流对称重盘的影响被最小化。 具有保护堤(1D)的安装构件(1),接合突起(1B)以及围绕开口(1C)以同心方式形成的最外周接合壁(1A),以通过其插入连接部分(2A) 设置在位于称量盘(2)的下表面上的称重装置的上壳体(3)上。 第一和第二防风壁(4,5)通过分别配合到接合凸缘1B和接合壁(1A)的内周壁定位,并且可以在必要时容易地移除,例如用于清洁。 例如,第二防风壁(5)形成为高于第一防风壁(4),从而能够有效地阻挡来自外部的气流。
