Abstract: PURPOSE:To mitigate degradation of steering sense due to the effect of the inertia of a motor for auxiliary steering, and to improve the entire efficiency in a simple structure. CONSTITUTION:An outer roller 33 of a planetary roller reduction gear 13 arranged between an output shaft 8a of a motor for auxiliary steering and a transmission shaft 7 to a steering mechanism, is rotatively supported between a pair of side plates 37 and 38 through thrust needle bearings 39a, 39b. An external gear tooth 33a is formed on the outer periphery of the outer roller 33, and a pinion 10 biting into this is fixed to the outer shaft of a variable motor 9, and the outer roller 33 is rotated and driven around the axis of the planetary roller reduction gear 13 by the rotation of the variable speed motor 9. When the outer roller 33 is rotated in the same direction as the revolving direction of planetary rollers 32, 32... around a revolving axis of a transmission shaft 7, the reduction ratio of the planetary roller reduction gear 13 becomes smaller, and when the outer roller 33 is rotated in the reverse direction, the reduction ratio of the planetary roller reduction gear 13 becomes larger, and the auxiliary steering force transmitted to the transmission shaft 7 is thus increased or reduced.

Title: Implantation type electroluminescent device and its manufacture
Inventor: KISHIMOTO YOSHIO
IPC: H05B33/10
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To suppress the aging effect of luminance, the rise of a drive voltage, the occurrence of a black point by causing both the surface of a transparent substrate and the surface of a positive hole implanting transparent electrode to have hydrophobic surface of a molecule structure without active hydrogen. SOLUTION: An active hydrogen-existing place in an element is mainly the surface of a substrate of inorganic material such as glass or a transparent electrode. By constituting the same into hydrophobic, no ion exist between the electrodes so that no electrolyte reaction occurs, no gas generation occurs, no chemical change of the material occurs, and only electron conduction occurs so as to obtain an luminescence element stably operating for a long period. Preferably, a molecule structure without active hydrogen on the hydrophobic surface is the aromatic molecule structure without both O-H bonding and N-H bonding. Since the same adsorbs no water and has the aromatic molecule structure, an electrode having high affinity with organic molecules constituting the element can be composed, no barrier nor separation occurs between layers, and the whole element is integrated.  As the aromatic molecule structure, tertiary aromatic amine is illustrated.
