Abstract: An engine test apparatus includes a dynamometer connected to an engine through a shaft, and a control calculation device configured to control operations of the engine and the dynamometer. The shaft has one end connected to an output shaft of the engine, and the other end connected to a rotation shaft of the dynamometer, and includes a Doppler velocimeter configured to emit laser light to the one end of the shaft or the output shaft of the engine to contactlessly measure a rotation speed of the output shaft of the engine, and transmit the measured rotation speed to the control calculation device. The control calculation device uses the rotation speed transmitted from the Doppler velocimeter to control the operation of the dynamometer.

Abstract: A weighing apparatus is provided that quantifies an impact load based on an electrical output from a mass sensor to prevent damage to the mass sensor by disclosing the degree of impact to a user. The weighing apparatus includes a weighing unit on which an object is placed and a mass sensor that receives the mass×acceleration of gravity of the object as a load and measures mass from an electrical signal corresponding to displacement of an internal structure of the apparatus. The apparatus quantifies and records the amount of the displacement, and determines acceleration by a numerical calculation from the displacement data. The obtained acceleration quantifies the amount of impact applied on the weighing apparatus by the object, and may be used to warn the user when the weighing apparatus is in danger of damage.

Abstract: To prevent measurement errors caused by impact including an impact load transmitted at high speed or static electricity and prevent destruction of a sensor unit due to the above-mentioned impact load. Through-holes (12f) are formed in four corners of a pan receiver, upwardly protruding pieces (14a) of a plate spring fixed to a bottom surface of the pan receiver are inserted into the through-holes (12f), and pan receiver legs are attached to the upwardly protruding pieces (14a). When a pan is mounted on the pan receiver, four corners of the pan are supported by the upper surfaces of gel-like cushioning bodies and the upper ends of coil springs, impact applied to the pan including an impact load transmitted at high speed is absorbed by the gel-like cushioning bodies, and the lower ends of the coil springs contact the upwardly protruding pieces (14a) of the plate spring, so that the pan assumes a conducting state with the pan receiver via the coil springs and the plate spring, and even if the pan is charged with static electricity, the static electricity due to charging can be released to the pan receiver via the coil springs and the plate spring.
