摘要： A torsion bar of a torque detection device converts torque applied between an input shaft and an output shaft to a torsional displacement. A pair of yokes is secured to the output shaft, and forms a magnetic circuit in a magnetic field of a multipolar magnet secured to the input shaft. A magnetic flux guide member has a main body facing the yoke to guide magnetic flux of the magnetic circuit. A magnetic sensor is placed at an extension, and detects magnetic flux guided by the magnetic flux guide member. The magnetic flux guide member is configured to allow magnetic permeance per unit area between the magnetic flux guide member and the yoke to be greater at a location in the main body from which the extension is branched, than at a circumferential end portion of the main body.

摘要： A relay apparatus incorporates at least first and second relays having respective first and second electromagnetic coils, with a single yoke partially surrounding each of the coils. When current is passed through only the first electromagnetic coil, to activate the first relay, resultant magnetic flux acting on the armature of the second relay is attenuated by passing a current through the second electromagnetic coil to produce opposing-direction magnetic flux. When current is passed in the opposite direction through the second coil, to activate the second relay, the magnetic fluxes produced by the first and second electromagnetic coils become mutually reinforced, thereby reducing the power consumption required to activate both of the relays and to maintain that activated state.

摘要： A solenoid device includes two electromagnetic coils, two stationary cores, two plungers and a yoke that surrounds the two electromagnetic coils. When a first electromagnetic coil is energized, magnetic flux flows through a first magnetic circuit that includes the first stationary core. When the two electromagnetic coils are energized, magnetic flux of the first electromagnetic coil flows through the first magnetic circuit, and magnetic flux of the second electromagnetic coil flows through a second magnetic circuit that includes a second stationary core. When energization of the first electromagnetic coil is stopped while maintaining energization of the second electromagnetic coil, the magnetic flux of the second electromagnetic coil continues to flow through the second magnetic circuit and a third magnetic circuit that includes the two stationary cores. A magnetism limiting portion is disposed in a portion of the second magnetic circuit that does not overlap the third magnetic circuit.

摘要： A relay system is provided which is designed to avoid flow of inrush current through a capacitor in a pre-charge mode wherein the capacitor is pre-charged. The relay system includes a pair of power lines, a capacitor, a series-connected assembly, a control circuit, and a relay module. The relay module includes two main switches, a main coil, and a sub-coil. In the pre-charge mode, the control circuit energizes both the main and sub-coils to turn on only one of the main switches. Before entering the pre-charge mode, the control circuit diagnoses the sub-coil. When the sub-coil is determined as being malfunctioning, the control circuit inhibits the pre-charge mode from being entered.

摘要： A solenoid device is provided which is equipped with a first and a second magnetic coil and a first, a second, and a third magnetic circuit, and designed so that when the second magnetic coil is deenergized while the first magnetic coil is kept energized following a dual-energized mode in which the first and second magnetic coils are energized, the magnetic flux Φ flowing through the second magnetic circuit disappears. The magnetic flux Φ of the first magnetic coil, thus, continues to flow though the first and third magnetic circuits, thereby creating a magnetic force to keep a first plunger and a third plunger attracted. This enables the plungers to be attracted independently from each other and results in a decrease in power consumption of the magnetic coils when the plurality of plungers are attracted simultaneously.
