Abstract: The present invention relates to a rotor including a shaft sleeve having a shaft sleeve main body and a stopper formed to protrude outward from an end portion of the shaft sleeve main body; a magnet disposed on an outer circumferential surface of the shaft sleeve and a lower portion thereof is supported by the stopper; and a fixing part which fixes an upper portion of the magnet, and a torque sensor and an electronic power steering system including the same. Due to the above structure, a broken magnet is prevented from deviating even when a magnet is broken.

Abstract: The present disclosure provides an electro-mechanical fuse-type configuration built into the probe that contacts the specimen during materials testing. The design includes an internal pre-loaded compression spring and an electrical contact switch. The coil spring preloaded to the desired safety load results in the probe assembly directly passing the load from the probe tip to the load cell for loads under the point where the spring additionally compresses. Upon deflection of the spring in excess of safety preload, the spring internally compresses within the probe coupling rather than the probe tip continuing to displace into the specimen, thereby switching the state of the electrical contact switch and stopping operation of the materials testing device. In a further configuration, excessive travel of the load cell coupling is detected, and, in response, operation of the materials testing device is stopped.

Abstract: A method for creating a composite cable having at least one advanced termination on at least one end. An advanced termination is added to an end of a short synthetic tensile strength member. The strength of the tensile strength member and termination is then tested. Once tested satisfactorily, the short cable is spiced onto a long cable of the same type using prior art splicing techniques. The union of the short cable and the long cable creates a “composite” cable having a advanced termination on at least one end. In most applications it is preferable to set the length of the short cable so that the interwoven splice will exist at a desired location.

Abstract: A transducer assembly is provided. The transducer assembly includes a magnetic portion, a body, a tensile pulse transmitter, and a pulse and current control unit.

The body is disposed within an opening of the magnetic portion, and has a conductive portion configured to pass electric current near a body surface oriented toward the test surface. The tensile pulse transmitter is disposed within a cavity of the body and configured to transmit a tensile pulse into the test object. The pulse and current control unit is configured to control the tensile pulse transmitted by the tensile pulse transmitter, and to provide a current that passes through the conductive portion of the body and the test object, whereby a force urging the transducer assembly and the test object toward each other is generated responsive to the magnetic field and the current.

Abstract: A force detecting device includes a first base section, a second base section, and a charge output element arranged between the first base section and the second base section. The charge output element includes a first board formed by a Y-cut quartz plate and a second board formed by a Y-cut quartz plate. The boards are laminated in a direction orthogonal to the normal an attachment surface of the second base section. The force detecting device detects an external force on the basis of a first output corresponding to a shearing force in a first detection direction orthogonal to the laminating direction of the first board and a second output corresponding to a shearing force in a second detection direction orthogonal to the laminating direction of the second board and crossing the first detection direction.

Abstract: A displacement detection device includes a piezoelectric sensor. The piezoelectric sensor is provided with a piezoelectric sheet on both principal surfaces of which detection electrodes are formed. When stress is applied to the piezoelectric sensor, charge is generated, and an output voltage in accordance with this generated charge is detected in a DC voltage detector. A controller measures this output voltage at a predetermined time interval. Every time the controller measures the output voltage, the controller makes a short-circuit control of a switch, and causes the charge generated in the piezoelectric sensor to be released. The controller can thereby detect an amount of change in output voltage generated at the predetermined time interval in accordance with an amount of displacement of the piezoelectric sensor. By sequentially integrating this, the controller can accurately detect the amount of displacement of the piezoelectric sensor which changes across measurement timings.
