摘要： The invention detects the position of an eye in image of a driver's face quickly and with high reliability, even if the density of the driver's face image is not uniform on the right and left sides due to direct sunlight. Only one eye detection area is obtained on the dark side of the face image when the density of the face image is not uniform on the right and left sides. One eye window is detected in the one eye detection area, and an iris center is detected within the eye window to discriminate an inattentive driver who is dozing.

摘要： Gamma-butyrolactone is prepared by catalytic dehydrogenation of 1,4-butanediol in a gaseous phase in the presence of a catalyst comprising copper, chromium, and manganese and/or barium. Improvement is in that the catalyst further contains sodium and/or potassium, whereby formation of by-products is suppressed and high yield, high selectivity and prolonged catalyst life are attained.

摘要： A system for measuring a traveling direction of a vehicle includes a geomagnetic sensor and a gyro sensor. The system utilizes first and second indices for deriving the vehicle traveling direction. The first index is indicative of a disturbance of the geomagnetic field on a short distance basis, and the second index is indicative of a disturbance of the geomagnetic field on a long distance basis. The system varies a rate of dependence upon the geomagnetic sensor and the gyro sensor based on values of the first and second indices when calculating the vehicle traveling direction.

摘要： A rack and pinion type steering apparatus in accordance with the present invention is provided with a rack guide made of synthetic resin. On the outer periphery of the rack guide is disposed a taper-form rib extending from the topmost portion of both outer sides of a concave one end-surface toward the portion of both outer sides of the other end-surface of the axial direction. The width of the rib becomes greater as it goes from the other end-surface of the axial direction toward one end-surface which is engaged with the back surface of the rack shaft. As a result, the concave portion of the one end-surface of the axial direction is hard to shrink inwardly when being molded, thereby the diameter of the one end-surface of the axial direction and that of the other end-surface of the axial direction of the rack guide are substantially the same.
