摘要： A current sensor includes units each of which has a bus bar through which current flows, a magnetic sensor facing one of plate surfaces of the bus bar, a shield facing the other plate surface. The units have a large-current unit and a small-current unit. A first distance between the bus bar and the magnetic sensor in a normal direction of the plate surfaces of the bus bar is the same as a distance L1A of the large-current unit and a distance L1B of the small-current unit. Since, as for a second distance between the bus bar and a base of the shield, a distance L2A of the large-current unit is larger than a distance L2B of the small-current unit, a measurement range of the large-current unit is widened and a measurement error due to magnetic saturation of the shield is suppressed.

摘要： An electrode member includes a first electrode pattern and a second electrode pattern. In each of the first electrode pattern and the second electrode pattern, first end portion wires of the first thin metal wires form a pair across the insulation gap, and first end surfaces of the paired first end portion wires are located so as to include portions that face each other with a predetermined distance therebetween in a direction that intersects a first direction. In each of the first electrode pattern and the second electrode pattern, second end portion wires of the second thin metal wires form a pair across the insulation gap, and second end surfaces of the paired second end portion wires are located so as to include portions that face each other with a predetermined distance therebetween in a direction that intersects a second direction.

摘要： A capacitance detection device has: a first capacitor disposed in the path between a first node connected to a detection electrode and a second node; a second capacitor disposed in the path between the first node and the ground; a third capacitor disposed in the path between the first node and a third node connected to a shield electrode placed in proximity to the detection electrode; an alternating-current voltage output circuit that outputs a first alternating-current voltage to the third node; a first attenuation circuit that outputs a second alternating-current voltage resulting from attenuating the amplitude of the first alternating-current voltage; and a charge amplifier that supplies charge to the first capacitor through the second node and outputs a detection signal matching the supplied charge.

摘要： A noise canceling adaptive filter outputs, from a front seat speaker, a noise canceling sound generated by applying a transfer function X(z) adapted by an adaptive operation using an output of a front seat microphone as an error to an output sound of a sound source apparatus. An output of the front seat microphone is added to an output of an audio feedback canceling filter by a second adder, added to an output sound of the sound source apparatus by a third adder, and output from a rear seat speaker. The audio feedback canceling filter applies a transfer function X′(z) and a transfer function C{circumflex over ( )}(z) on an output of the second adder and outputs a resultant. The transfer function C{circumflex over ( )}(z) corresponds to a transfer function C(z) from the front seat speaker to the front seat microphone. In synchronization control, the transfer function X(z) is set as the transfer function X′(z).

摘要： A tire wear measurement device detects a magnetic field of a magnetic body embedded in a tread portion of a tire and measures the degree of wear of the tire from a change in the magnetic field. The tire wear measurement device includes a first magnetic field detection portion placed at a position at which the magnetic field of the magnetic body can be detected, and a second magnetic field detection portion disposed at a position at which the intensity of the magnetic field of the magnetic body differs from the intensity at the position at which the first magnetic field detection portion is disposed.

摘要： A controller controls an operating device. The operating device includes an operating member capable of being pushed by an operator, a biasing unit biasing the operating member in a return direction, a detecting unit configured to detect a distance of movement of the operating member and output a detection signal indicating the distance of movement, and a braking unit configured to brake movement of the operating member. In response to determining, based on the detection signal, that the operating member is pushed into a predetermined retracted position, the controller causes the braking unit to hold the operating member pushed. In response to determining, based on the detection signal, that the operating member is moved in the return direction because of a clearance in a drive transmission system between the operating member and the braking unit, the controller causes the braking unit to stop holding the operating member.

摘要： A through hole is formed in an inner-side yoke making up a magnetic circuit portion, passing therethrough following a vibration direction of a vibration unit, and circuit boards are disposed in the through hole. The circuit boards are disposed with board surfaces thereof following the vibration direction of the vibration unit. Also, an opening area of a middle space across which the circuit boards oppose each other is larger than opening areas of side spaces. Accordingly, flow quantity of air through the through hole can be obtained, increase in air resistance at the time of vibration of the vibration unit can be suppressed, and also wind velocity can be obtained, whereby cooling effects of heat-generating components mounted on the circuit boards can be improved.
