摘要： A constant velocity counter track joint having an outer joint part with outer ball tracks having first tracks opening toward the aperture end and second tracks opening toward the attaching end. The center line of the second tracks, departs, radially inwardly, a first reference radius centered in the point of intersection of a perpendicular line on the tangent at the center line of the ball track and the longitudinal axis. In the inner joint part, the center line of the ball tracks departs, radially inwardly, a second reference radius centered in the point of intersection of a perpendicular line on the tangent at the center line of the ball track and the longitudinal axis. In the outer joint part, the center line of the ball tracks towards the aperture end, moves radially outwardly beyond said first reference radius. In the inner joint part, the center line of the ball tracks towards the attaching end, moves radially outwardly beyond said second reference radius.

摘要： A constant velocity joint assembly comprises outer and inner joint members having engaging contact surfaces which support the joint for articulation about a common center point. The joint members have ball grooves which diverge inwardly of the joint and whose inner and outer ball groove surfaces are axially offset with respect to the center point for urging the balls axially inwardly. A ball retainer is provided within the outer joint member. The ball retainer is spring-biased into engagement with an end of the inner joint member and pivots about the center point of the joint to engage and hold the balls within the ball grooves, maintaining them in a common plane.

摘要： An infrared intensity detector having a pair of detector elements, one shielded from and the other exposed to an incoming infrared radiation, and a thermostatted black body reference source of a characteristic temperature. The detector elements are made of a semiconductor having a remarkable temperature dependence of resistivity within a limited temperature range around the characteristic temperature. The detector offers increased detection sensitivity and finds a wide variety of applications especially where it is intended to measure an object of relatively low temperature.

摘要： A fixed type constant velocity universal joint has track grooves of an outer joint member including first and second track groove portions located on depth and opening sides, respectively. The first track groove portions each have a circular-arc part having a curvature center that is not offset in an axial direction with respect to a joint center, are inclined in a circumferential direction with respect to a joint axial line, and are adjacent to each other in the circumferential direction with their inclination directions opposite to each other. The second track groove portions have a different shape than the first track groove portions to increase an effective track length with respect to a maximum operating angle. The first and second track groove portions are connected respectively to each other on the opening side with respect to the joint center.

摘要： A constant velocity fixed joint. The center line (M22) of the outer ball tracks (22) towards a first side (S1) departs, radially inwardly, a reference radius centered in the point of intersection between a perpendicular line on tangents (T22) at the center line (M22), and the longitudinal axis (L12). The center line (M23) of the inner ball tracks (23) towards a second side (S2) departs, radially inwardly, a reference radius centered in the point of intersection of a perpendicular line on the tangent at the center line (M23), and the longitudinal axis (L13). In the outer joint part, from the joint center plane (EM) to the second side (S2), the center line (M22) moves beyond the reference radius radially outwardly. In the inner joint part (13), from the joint center plane (EM) to the first side (S1), the center line (M23) moves beyond the reference radius, radially outwardly.
