摘要： A face image obtained by imaging a vehicle occupant by a CCD camera (10) is recorded in an image memory (140). A CPU (170) detects the position and the direction of a face of the occupant according to the face image recorded in the recording memory (140). The CPU (170) is triggered by an input from an obstacle detection sensor (60) to calculate a displacement amount and a rotation amount of a headrest (200) according to the face and the direction of the face of the occupant against the headrest (200) and the direction and the speed of the obstacle against the vehicle and adjust the position and angle of the headrest (200) by driving a motor (211).

摘要： A headrest apparatus for a vehicle includes a headrest rear portion, a headrest front portion being movable between a fully closed position and a fully open position, a driving means for moving the headrest front portion, a capacitance sensor provided at the headrest front portion for detecting a change in capacitance, and a controlling means for controlling the driving means and comparing an amount of change in capacitance detected by the capacitance sensor to a predetermined threshold value when the headrest front portion moves towards the fully open position. The controlling means determines that the headrest front portion is positioned close to a head of an occupant when the amount of change in capacitance exceeds the threshold value. Further, the controlling means detects a capacitance change per unit moving distance of the capacitance sensor at a predetermined timing and changes the threshold value based on the detected result.

摘要： Rare earth magnet scrap and/or sludge is remelted for reuse. Once a rare earth-free magnet-constituent metal feed is loaded in a melting furnace and heated into a melt, a rare earth-containing metal feed and the rare earth magnet scrap and/or sludge are added to the melt, a particulate flux of an alkali metal, alkaline earth metal or rare earth metal halide and having an average particle size of 1-50 μm, preferably wrapped in a metal foil, is added to the melt, and the resulting mixture is melted, from which an alloy ingot is obtained. The valuable elements in the scrap and/or sludge can be recycled. Better separation between the slag and the molten metal ensures that the ingot is obtained from the melt in a high yield.

摘要： Disclosed is a thin alloy ribbon prepared by the strip casting method as an intermediate for the preparation of a sintered rare earth-based permanent magnet or in particular, a neodymium/iron/boron-type permanent magnet. The thin alloy ribbon is characterized by a specific volume fraction of the four-phase coexisting region consisting of the &agr;-iron phase, R-rich phase, RxT4B4 phase and R2T14B phase each having an average grain diameter in a specified range and a specific volume fraction of the chill crystalline phase. When these requirements are satisfied, the sintered rare earth-based permanent magnet prepared from the thin alloy ribbons can be imparted with improved magnetic properties and high sintering density even without increasing the sintering temperature.
