    摘要： An objective is to detect a resolver malfunction without fail, using a low-cost resolver having the small number of the poles, and a control-motor system having advantage in small sizing and high-power outputting. In the control-motor system, the system for driving a 2m-pole motor based on a rotor rotation angle θ detected by a 2n-pole resolver, where m and n being counting numbers, is characterized in that: the sum of the square of a signal modulated by sin θ and the square of a signal modulated by cos θ in the resolver in which an excitation signal generated in said system is modulated by sin θ and cos θ in response to the rotor rotation angle θ of the resolver is compared to a predetermined malfunction threshold value, so that malfunction determination related to the resolver is performed, and also, given that the sum is a2 when the resolver is recognized to be in normal operation, the malfunction determination threshold value is made to be not smaller than {a×cos((π/2)/(m/n))}2.

    摘要： A low-cost torque detection apparatus is obtained using wheel revolution sensors which are generally provided in a conventional ABS and an engine revolution sensor which is generally provided in a conventional engine fuel jet controller. The apparatus can be used, for example, in a vehicle having a drive source, such as an engine or a motor, for driving wheels which is coupled to the right and left wheels by respective shafts having torsional stiffness for transmitting a drive torque through a differential gear. The apparatus includes a drive source revolution angle detection device for the drive source and wheel revolution angle detection means for the right and left wheels, and calculates torques of shafts such as drive shafts for coupling the differential gear to the wheels using a torque calculator.

    摘要： A semiconductor device includes: an insulation layer; a fuse layer extending on the insulation layer in one direction and disconnected through light radiation to control a redundant circuit; a pseudo fuse layer on the insulation layer along at least one side of the fuse layer; another insulation layer covering the fuse layer and the pseudo fuse layer; and a protection film formed on another insulation layer and having an opening in a region opposite to the fuse layer. Fuse layers having a spacing of less than 4 &mgr;m or 4.5 to 5.5 &mgr;m. Such a structure allows a semiconductor device with a fuse layer capable of being disconnected reliably and providing a smaller blow trace.

    摘要： A anti-skid control system detects a torsion torque applied to each of the wheels of a vehicle, and controls a braking force on the basis of a corrected acceleration as a wheel acceleration is corrected by the detected torsion torque. The corrected acceleration Gc can approximately be expressed by Gc=(Kr/Iw)(.mu..multidot.W.multidot.r-Tb), where Iw, inertia moment of the wheel .omega., angular velocity of the wheel (the turning direction of the wheel when it advances is positive); Tt, torsion torque; .mu., friction coefficient of the road surface; W, load on the wheel; r, radius of the wheel; Tb, brake torque; Kr, constant.
