摘要： An open/close body control system for a vehicle can stabilize outputs of a pair of electrically operated motors (M1, M2) which drive an open/close body for a vehicle. Speeds of the electrically-operated motor (M1, M2) are synchronously controlled such that predictive positions (XLt+1, XRt+1) of electrically-operated motor (M1, M2) after a lapse of a unit time gradually approach a target position (XTRG) calculated based on present positions (XLt, XRt) and a target speed (&Dgr;XTRG) of the electrically-operated motors (M1, M2).

摘要： Disclosed is a novel thin ribbon of a rare earth/iron/boron-based magnet alloy prepared by quenching of an alloy melt by the method of strip casting, from which a sintered permanent magnet is obtained by the powder metallurgical method. The sintered permanent magnet can be imparted with greatly improved magnetic properties or, in particular, residual magnetic flux density when the thin alloy ribbon as the base material thereof has a metallographic phase structure containing “four-phase regions” consisting of (a) an &agr;-iron phase, (b) a R-rich phase, in which R is a rare earth element selected from praseodymium, neodymium, terbium and dysprosium, (c) a RxT4B4 phase, in which T is iron or a combination of iron and a transition metal element other than iron and rare earth elements and x is a positive number varying with the rare earth element, and (d) a R2T14B phase, in which R and T each have the same meaning as defined above, each phase being dispersed with a grain diameter in a limited range, in a volume fraction of from 1 to 10%.

摘要： A rain drop detecting device includes an oscillation element disposed on a plate member such as a windshield for generating an ultrasonic wave on the plate member, an ultrasonic wave receiving element disposed on the plate member for receiving the ultrasonic wave generated by the oscillation element, a detecting device connected to the ultrasonic wave receiving element for detecting an amplitude of the ultrasonic wave, and an ultrasonic wave absorbing member disposed on the plate member. The absorbing member is designed to absorb a portion of the ultrasonic wave generated by the oscillation element to prevent the downwardly travelling portion of the ultrasonic wave from travelling beyond a desired region of the plate member. In the case of a windshield, the absorbing member can be used to prevent the ultrasonic wave from travelling to the resting location of the wiper so that inadvertent rain drop detection does not occur.
