摘要:
An engine start controller shortens the time required from when an operation switch is operated to when an engine is started. The engine start controller controls starting of the engine of a vehicle and power supply to an electric device system. A control unit selectively locks the steering shaft of the vehicle and performs authentication with a portable device, which is carried by a user of the vehicle, for permitting use of the vehicle. An operation switch is connected to the control unit and generates an operation signal when operated by the user. The control unit unlocks the steering shaft in parallel with supplying power to the electric device system when the operation signal is generated and use of the vehicle is permitted through the authentication.

A start control apparatus has a steering lock mechanism, which includes a lock pin and a lock control unit. The lock pin is selectively engaged and disengaged from the steering shaft. The lock control unit controls the lock pin. The start control apparatus further includes a portable communication device, a verification control unit, which communicates with the portable communication device, a power source control unit, which control power supply, an engine control unit, which controls the engine, a lock state detecting switch, which detects an engaged state and a disengaged state of the lock pin. The lock control unit and the power source control unit monitor detection signals from the lock state detecting switch. The engine is permitted to be started on condition that the control units acknowledge that the lock bar is in the disengaged state.

An electric steering lock capable of outputting a signal correctly indicating an operation state of a steering lock mechanism even when the operation voltage of a lock detector decreases. The electric steering lock includes a CPU, a signal hold circuit, and an OR circuit. When the steering lock mechanism unlocks a steering wheel, an unlock sensor provides an H level detection signal to the CPU and the signal hold circuit. In response to the detection signal, the CPU issues a state hold command to the signal hold circuit. In response to the state hold command, the signal hold circuit generates an H level hold signal in correspondence with the detection signal. The OR circuit provides an H level signal to an immobilizer ECU when at least one of the detection signal from the unlock sensor or the hold signal has an H level.

A switch for urging a driver to perform an operation that is required when the smart ignition function is invalid. The switch is used by a driver to start the engine of a vehicle when the vehicle communicates with a portable device to verify the portable device. The portable device has an end portion. The switch includes a push button pushed by the driver. The push button includes a guide portion engaged with the end portion of the portable device.

A method is provided for producing magnetic green compacts. Material powder including a rare earth alloy and containing not less than 15 mass % of fine particles with particle diameter of not more than 2 μm is filled into a compacting mold, then compacted and compressed, and subjected to magnetic fields to give a green compact. A powder compact having a packing density 1.05 to 1.2 times the bulk density is subjected to a weak magnetic field of 1 to 2 T to give a compact. The magnetic field strength is increased to not less than 3 T at an excitation rate of 0.01 to 0.15 T/sec, and the strong magnetic field of not less than 3 T is applied to the compact by a high-temperature superconducting coil. The magnetic field is applied by the high-temperature superconducting coil in a direction opposite to a direction applied by a normal conducting coil.

The present invention provides a powder for a magnet which can form a rare earth magnet having excellent magnetic characteristics and which has excellent moldability, a method for producing the powder for a magnet, a powder compact, and a rare earth-iron-boron-based alloy material.Magnetic particles constituting a powder for a magnet each include a structure in which a particle of a phase 3 of a hydrogen compound of a rare earth element is dispersed in a phase 2 of an iron-containing material. Since the phase 2 of the iron-containing material is uniformly present in each of the magnetic particles 1, the powder has excellent moldability and easily increases the density of a powder compact 4. The powder for a magnet can be produced by heat-treating a powder of a rare earth-iron-boron-based alloy (R—Fe—B-based alloy) in a hydrogen atmosphere at a temperature equal to or higher than the disproportionation temperature of the R—Fe—B-based alloy to separate the powder into the rare earth element and the iron-containing material and to produce the hydrogen compound of the rare earth element. The powder compact 4 is produced by compacting the powder for a magnet. The powder compact 4 is heat-treated in a vacuum to produce a R—Fe—B-based alloy material 5, and the R—Fe—B-based alloy 5 is magnetized to produce a R—Fe—B-based alloy magnet 6.

A soft magnetic material includes a plurality of composite magnetic particles (30) each including an iron-based particle (10) containing iron and an insulating coating film (20) surrounding a surface of the iron-based particle (10). The insulating coating film contains an organic group derived from an organic acid having at least one substance selected from the group consisting of titanium, aluminum, silicon, calcium, magnesium, vanadium, chromium, strontium, and zirconium. The at least one substance in the insulating coating film (20) is bonded to iron in the iron-based particles (10) through the organic group derived from the organic acid in the insulating coating film (20). Furthermore, a method for producing a soft magnetic material includes the steps of preparing the iron-based particles (10) containing iron and forming the insulating coating film (20) surrounding a surface of each of the iron-based particles (10). In the step of forming the insulating coating film, the organic acid containing the substance is brought into contact with the surfaces of the iron-based particles (10).
