Abstract: A windshield for a balance is provided, and the windshield to be attached to a balance to define a weighing chamber, includes openable and closable doors constituting portions of the weighing chamber, opening and closing mechanisms configured to open and close the doors, sensors configured to detect movement of the doors, and a control unit configured to command the opening and closing mechanism to open and close the door when a movement of the door from a stationary state is detected by the sensors. When an operator slightly moves the door from a stationary state to open or close the door, the sensor detects this, and the door is automatically opened or closed.

Abstract: Provided is a windshield for a balance, for which opening and closing doors of the windshield are smoothly moved without wobbling, dust or the like is unlikely to accumulate on the part of guide rails that guide the opening and closing doors, and cleaning is easy. Upper portions of the pair of opening and closing doors of the windshield are respectively suspended by upper frames provided along respective side portions of an upper surface door, and the opening and closing doors are reciprocated by air cylinders by being guided by guide rails each formed of a horizontal portion and a vertical portion. On the respective horizontal portions, projections that restrict lower ends of the respective opening and closing doors from being displaced in separating directions from the vertical portions are provided along movement paths of the respective opening and closing doors.

Abstract: Provided are a static eliminator capable of performing quick static elimination while having a good ion balance, an electronic balance including the static eliminator, and a static eliminating method of the static eliminator. A static eliminator is provided which is configured to eliminate static from a static eliminating object by ions generated by applying high voltages to static eliminating needles, and has a high-speed static eliminating mode configured to eliminate static from a static eliminating object at a high speed, and a relaxation static eliminating mode to be executed by a voltage application method different from that of the high-speed static eliminating mode and configured to regulate ion balances of the static eliminating object and the area around of the static eliminating object. With this configuration, a static eliminator capable of quickly eliminating static from a specimen while having a good ion balance can be provided.

Abstract: Provided is an electronic balance that includes a windshield having a door to be automatically opened and closed, and has a high degree of freedom of design. An electronic balance including a balance main body that holds a weighing mechanism connected to a weighing pan, and a windshield including a frame and doors disposed slidably on the frame, and configured to form a weighing chamber by covering the weighing pan, and configured so that the windshield includes inside air cylinders connected to the doors to open and close the doors, and air pumps to drive the air cylinders, and is configured to be detachable from the balance main body. The windshield that has doors to be automatically opened and closed is detachable from the balance main body, so that the windshield and the balance main body can be designed separately, and therefore, the degree of freedom of design of the electronic balance is high.

Abstract: Provided is an electronic balance of electromagnetic force type including a weight automatic loading mechanism which can place and remove a weight by its own mechanism without use of either an external balance weight or a built-in balance weight. An electronic balance of electromagnetic force type is provided with a beam equilibrium setting unit that sets two or more equilibrium states of the beam position detecting unit. By making conversion ratios of upper and lower light receiving circuits nonequivalent, an imaginary weight is generated by utilizing the operating principle of the electromagnetic balance of electromagnetic force type.

Abstract: Provided is a new method of measuring an amount of movement of an animal. A measurement value of an animal as a measuring target is sequentially measured with a scale (21), an amount of change in the measurement value obtained in chronological order is calculated, and from division of the amount of change in the measurement value by a weight of the animal, an amount of movement of the animal is measured. Accordingly, weight differences between individual living bodies and in the process of breeding are eliminated, and an amount of movement of an animal based on changes in the weight of the living body can be measured.

Abstract: Provided is a mass sensor including a four-corner-adjusting-mechanism capable of reducing the sensitivity of four-corner adjustment without reducing the rigidity of a Roberval mechanism. A mass sensor (1) includes a Roberval mechanism (2) in which a floating frame (21) and a fixing frame (22) are connected by upper and lower sub-frames (23, 24) having thin portions (23b) formed thereon, and a four-corner-adjusting-mechanism (4) to perform parallelism adjustment. The four-corner-adjusting-mechanism (4) includes an adjusting screw (41), and an upper elastic member (42u) and a lower elastic member (42d) disposed in series in the vertical direction so as to sandwich the sub-frame (23) to be subjected to parallelism adjustment.
