摘要： PROBLEM TO BE SOLVED: To minimize an occurrence of convection in a measurement chamber caused by opening/closing a door of the measurement chamber, with a relatively simple configuration.SOLUTION: A weighing device is configured by partitioning a measurement space 5 into upper space and lower space with a partition plate 4 to form, in the lower space, a measurement chamber 7 whose capacity is smaller than the measurement space 5 so that, even if convection occurs in the measurement chamber, the convection stops in a short period of time. Additionally, suspending walls 9a and 9b are attached on side edges of the partition plate 4 adjacent to doors 10a and 10b along the open/close direction of the doors 10a and 10b. Even when the door 10a or 10b is opened, a warm air layer staying in an upper part of the measurement chamber 7 is limited in the amount to flow out or blocked from flowing out by the suspending walls 9a and 9b. Therefore, convection does not occur in the measurement chamber 7, or a little convection occurs and stops in a short period of time, which does not affect measurement operation. The upper space can be used for other purpose such as a neutralization chamber.
摘要翻译：要解决的问题：以相对简单的结构，最小化由测量室的门打开或关闭引起的测量室中的对流的发生。解决方案：称重装置通过用隔板4将测量空间5分隔成上部空间和下部空间来构造，以在下部空间中形成容量小于测量空间5的测量室7，使得即使在测量室中发生对流，对流也会在短时间内停止。此外，悬挂壁9a和9b沿着门10a和10b的打开/关闭方向附接在隔板4的邻近门10a和10b的侧边缘上。即使打开门10a或10b，保持在测量室7的上部的暖空气层被限制流出或阻止由悬挂壁9a和9b流出的量。因此，在测量室7中不会发生对流，或者在短时间内发生少量对流而停止，这不影响测量操作。上部空间可用于其他目的，如中和室。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To suppress an effect of airflow on a weighing pan to the minimum in a comparatively simple structure. SOLUTION: A mounting member 1 is disposed on a casing 3 on a weighing apparatus located at the lower surface of the weighing pan 2. In the mounting member 1, a connection part 2A is inserted through an opening 1C, and a protection bank 1D, an engagement protrusion 1B, and an engagement wall 1A in the most outer circumferential part are formed in a concentric shape about the opening 1C. A second windshield wall 5 is fitted into the engagement wall 1A, and a first windshield wall 4 is fitted into the inner circumferential wall of the engagement protrusion 1B. For example, the wall height of the second windshield wall 5 is larger than that of the first windshield wall 4, and the airflow from the outside is thereby efficiently blocked. Because each of the windshield walls 4, 5 is merely fitted into the engagement protrusion 1B and the engagement wall 1A, it is easily detached therefrom if necessary, for example, for cleaning.

摘要翻译：要解决的问题：以比较简单的结构将气垫对称重盘的影响抑制到最小。
解决方案：安装构件1设置在位于称重盘2的下表面的称重装置上的壳体3上。在安装构件1中，连接部2A通过开口1C插入，并且保护堤1D，接合突起1B和最外周部的接合壁1A围绕开口1C形成为同心的形状。第二挡风玻璃壁5装配到接合壁1A中，并且第一挡风玻璃壁4装配到接合突起1B的内周壁中。例如，第二挡风墙5的壁高比第一挡风玻璃壁4的壁高，从而有效地阻挡来自外部的气流。因为每个挡风玻璃壁4,5仅装配到接合突起1B和接合壁1A中，所以如果需要，例如用于清洁，容易将其分离。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To constitute a heating/drying type moisture meter for heating a sample using an electromagnetic induction system. SOLUTION: A magnetic field producing part 6 is arranged to the upper part of a weighing tray 4 [constitution of (A)], a magnetic field producing part 7 is arranged to the circumference of the weighing tray 4 [constitution of (B)] or a magnetic field producing part 8 is arranged to the lower part of the weighing tray 4 [constitution of (C)]. The weighing tray 4 generates heat by the eddy current caused by the electromagnetic induction due to the magnetic fluxes of the magnetic field producing parts 6, 7 and 8 and the sample on the weighing tray 4 is heated and dried. The weight of the sample before heating and drying is measured by a weight sensor 3, and the weight of the sample after heating and drying is measured, so that the moisture content of the sample is measured from both weight measuring results.

摘要： PROBLEM TO BE SOLVED: To effectively perform moisture proofing with respect to a force coil unit that is arranged to an air gap of magnetic field formed by a permanent magnet.
SOLUTION: By inserting the force coil 2 that is an air core until the upper end of the coil abuts against the lower end of the flange part 1b of a bobbin 1 with respect to the bobbin 1, the force coil unit 3 is formed by from the bobbin 1 and the force coil 2. With respect to the force coil unit 3 in this state, a moisture-proofing layer 4 is formed with at least the force coil 1 exposed to the outer atmosphere, by using the method of injection molding with liquid crystal resin. As a result, the variation of the mass of the force coil unit 3 as a whole, caused by the moisture absorption and moisture release to/from the force coil 1 can be reduced, as much as possible, and the drift of the zero point as an electronic balance is prevented.

摘要： PROBLEM TO BE SOLVED: To heighten accuracy as a Roberval mechanism and to reduce assembly man-hour in the assembly type Roberval mechanism.
SOLUTION: Side walls 5, 11 are formed respectively on upper and lower subrod constituting members 1, 2, to thereby secure rigidity as the subrod constituting members. Notches are formed on the side wall 5 of the upper subrod constituting member 1, and 6A and 6B are formed corresponding to the notched parts, and deformed parts 10Aa-10Bb are formed relative to the upper subrod constituting member 1 at the parts. Similarly, deformed parts 17Aa-17Bb are formed on notched parts on the side wall 11 relative to the lower subrod constituting member 2. Since a fixed block member 3 and a movable block member 4 having high rigidity respectively are installed on both ends of both subrod constituting members 1, 2 and the upper and lower subrod parts 7, 13 are reinforced by reinforcement parts 5a, 11a, a stress caused by a load to the movable block member 4 side is concentrated onto the deformed parts 10Aa-17Bb, to thereby guarantee high accuracy as this Roberval mechanism.
