IPC: F16H61/04
Filed: 1989-06-26
Abstract: A control apparatus for an automatic transmission having a torque converter is so adapted that first a comparatively high-speed change ratio is set when there is a range changeover between the reverse range R and a forward cruising range (e.g., D, S, or L). This comparatively high-speed change ratio is maintained until it is detected that the gear mechanism of the automatic transmission is substantially formed for this high change ratio. A transition is made to a low-speed change ratio after it is confirmed that the gear mechanism is substantially formed for the high change ratio. By virtue of this operation, the torque delivered by the output shaft of the transmission assumes a step-shaped form in the course of the transition from the high-speed change ratio to the low-speed change ratio. As a result, a large transmission shock is minimized.

Abstract: Tocopherol homologues found in a tocopherol-containing feed material can be purified by forming a borate tocopherol ester and then distilling the material containing the esterified tocopherol to remove the materials boiling at temperatures lower than the esterified tocopherol. The borate tocopherol esters remaining after distillation are then reacted with a member selected from the group consisting of: Water, methanol, and ethanol to form tocopherol homologues from the borate tocopherol ester, and the boron by product from this reaction is removed. The tocopherol is then recovered by collecting it, distilling it or by any other convenient collection method.

Abstract: PURPOSE:To improve the light distribution on the turning locus of a car, by turning the headlight to the turning direction of the car and rotating the headlight in the reverse inclination direction to the car inclination in the same angle, depending on a car speed, the turning radius, and the car body inclination detected by a car speed detector and a car inclination detector. CONSTITUTION:In conering, the turning radius is computed from the car speed and the car inclination detected by a car speed detector and a gyroscope meter 7 as a car body inclination detector. Also the car inclination theta1 is computed by the car body inclination detector. The headlight 2 is rotated from the optical axis I to the optical axis II by an optical axis adjusting angle theta2 responding to he turning radius, to take a radiation area D2. In that, the useless area D2 so far is negated and the radiation area on the turning locus A is increased to provide a more bright field of vision. Furthermore, by rotating the headlight 2 in the direction reverse to the inclination of the car body by the inclination theta1, the upper limit of the light distribution on the turning locus A is now on the HL2 line to improve the field of vision in the shaded portion.

Abstract: In electronic reproduction technology, a recognition circuit for hues and colors in colored surfaces is provided. Before the actual hue recognition, the hue to be recognized is selected and its prescribed or measured color values of the RGB color space are transformed by a first color transformation into chrominance values of the chrominance/luminance color space, whereby the transformation coefficients are defined such that the transformed color locus of the hue to be recognized lies on a rotated X'Y' color coordinate system in the chrominance plane. During the actual hue recognition, the colored surface is opto-electronically scanned and the measured color values acquired are transformed into chrominance values by a second color transformation with the transformation coefficients defined in the first color transformation. By selection of chrominance values and by quotient formation of the selected chrominance values, a hue signal which is a measure for hue deviation of the scanned hues from the hue to be recognized is generated. After combination of the hue signal with an auxiliary control signal, a hue recognition signal is formed, this being unequal to zero when the scanned hues lie within a sector-shaped hue recognition region. For color recognition, a color saturation signal and a luminance signal are additionally generated. The color saturation signal and luminance signal are adjustably limited in terms of amplitude and are combined with the hue recognition signal to form a color recognition signal.
