    摘要: An electrical connector includes an anode for conducting an electrical supply current from a source to a destination, a cathode for conducting an electrical return current from the destination to the source, and an insulator that prevents electrical conduction between the anode and the cathode. The first and second shapes are such as to provide a conformity of one to the other, with the insulator placed therebetween and having a predetermined relatively thin thickness. A predetermined low-resistance path for the supply current is provided respectively by the anode and the cathode, and a proximity of the anode to the cathode along these paths provides a predetermined low self-inductance of the connector. The anode and the cathode each comprises a plurality of sections that are disposed at one or more predetermined angles to form a rigid assembly that accommodates a geometry between the source and the destination.

    摘要: There is a problem that memory protection against access to a shared memory by a sub-arithmetic unit used by a program executed in a main-arithmetic unit cannot be performed in a related-art semiconductor device. According to one embodiment, a semiconductor device includes a sub-arithmetic unit configured to execute a process of a part of a program executed by a main-arithmetic unit, and a shared memory shared by the main-arithmetic unit and the sub-arithmetic unit, in which the sub-arithmetic unit includes a memory protection unit configured to permit or prohibit access to the shared memory based on an access permission range address value provided from the main-arithmetic unit, the access to the shared memory being access that arises from a process executed by the sub-arithmetic unit.

    摘要: A variable valve mechanism of an internal combustion engine includes a cam, a transmission mechanism, a first variable device that controls the transmission mechanism to continuously change at least a maximum lift amount of a lift curve indicating a lift amount of a valve that corresponds to a rotation angle of the internal combustion engine, and a second variable device that controls the transmission mechanism to continuously change at least an operation angle of the lift curve. When the lift curve lies in any condition within a predetermined range that covers all or part of a variable range of the lift curve, an absolute value of a ratio of a maximum lift amount variation to an operation angle variation for a slight change from the condition caused by the first variable device is larger than that for a slight change from the condition caused by the second variable device.

    摘要: There is provided a semiconductor device that can follow a fast voltage change such as a large voltage drop occurring at the time of rapid load fluctuation. The semiconductor device includes a voltage sensor which monitors a power supply voltage at a sampling speed higher than the assumed frequency of power supply voltage fluctuation and outputs a voltage code value, a voltage drop determination circuit which determines, from the voltage code value, that a voltage drop causing a malfunction of a system occurs, and outputs a clock stop signal, and a clock control circuit which controls clock stop, restart, and frequency change.

    摘要: A current sensor includes, a bus bar through which a current flows, a magnetic detection element detecting a magnetic field intensity generated by the current, first and second shielding plates arranged so as to sandwich the bus bar between the first and second shielding plates, a first conductive plate made of a conductive nonmagnetic material, arranged between the bus bar and the first shielding plate, and a second conductive plate made of the conductive nonmagnetic material, arranged between the bus bar and the second shielding plate, wherein the magnetic detection element is arranged at a first conductive plate-side. A distance between the first conductive plate and the bus bar is longer than a distance between the second conductive plate and the bus bar. The first conductive plate includes a slit formed in the first conductive plate at an overlapping position, and the slit pierces the first conductive plate.
