    摘要： An apparatus and use of the apparatus for monitoring a current-carrying device wherein at least one acceleration sensor produces acceleration measurement values and a communication device transmits produced acceleration measurement values. A power supply unit is for the acceleration sensor and the communication device. The power supply unit includes an induction plate of a metallic material and a conductor loop extending around the induction plate and produces a power supply for the acceleration sensor and the communication device exclusively through induction from an electromagnetic alternating field of the current-carrying device. The apparatus can be positioned in a closed housing having a housing wall and the induction plate can be at least a subregion of the housing wall.

    摘要： An actual slip amount (S) of a torque converter is calculated by subtracting an actual input shaft rotational speed (Nr) of an automatic transmission from an engine rotational speed (Ne), which is the rotational speed of a crankshaft. Then, an engine rotational speed for display (Nd) is calculated by adding a slip amount adjusted for display (Sp), which is obtained by applying a predetermined correction process to the actual slip amount (S) to the actual input shaft rotational speed (Nr). The above described correction process may be a first-order-lag filter processing, for example. Thus, even when the actual slip amount (S) temporarily increases or decreases, a temporary increase or decrease in the engine rotational speed for display (Nd) may be suppressed. In other words, fluctuation or variation in the engine rotational speed for display (Nd) is suppressed. Further, Further, it is possible to provide the driver with a visually excellent direct-feeling display of engine speed Nd without impairing the drivability.

    摘要： A driver device that forms an oscillation loop with a vibrator and causes the vibrator to produce driving vibrations includes a current-voltage converter that is provided in the oscillation loop and converts a current that flows through the vibrator into a voltage, and a GCA as a comparator that is provided in the oscillation loop and outputs a signal corresponding to a comparison result between an output from the current-voltage converter and a given voltage. The GCA outputs a first high-level voltage or a low-level voltage during oscillation startup, and outputs a second high-level voltage or the low-level voltage in a steady oscillation state. The first high-level voltage is a voltage higher in potential than the second high-level voltage.

    摘要： A detector is made up of a semiconductor integrated circuit in a part, and the semiconductor integrated circuit includes a driving circuit, an AC amplifier, a detection circuit and an amplifier circuit. An input resistor that is connected to input terminals of an operational amplifier includes an internal input resistor made up of a semiconductor integrated circuit element and an external input resistor made up of an external discrete component connected to each other in parallel. Temperature characteristics of an angular velocity sensor is compensated by a temperature coefficient (a3) that is a combination of a temperature coefficient (al) of the internal input resistor and a temperature coefficient (a2) of the external input resistor.
