摘要： An apparatus for controlling valve timing in an internal-combustion engine. The apparatus includes a pair of telescoping sleeve members. One of the sleeve members is connected to the camshaft of the engine with a bolt, and the other sleeve member is connected to a timing pulley which is connected to the crankshaft of the engine. Each of the sleeve members has at least one slit which is located adjacent to a slit on the other sleeve member. The adjacent slits are angled relative to each other. Abutment rollers are arranged in the slits and are mounted on an axially movable member. The movable member is connected via a screw mechanism to a rotary motor. The rotational movement of the output shaft of the motor is changed to a linear movement of the support member, thereby causing the support member to move, which movement, in turn, causes the generation of angular displacement between the sleeve members so that variable valve-timing is obtained. The output shaft is hollow and is, on the inner end thereof, open to the head portion of the bolt. The other end of the shaft is closed with a plug.

摘要： An oil seal apparatus, particularly for use with a vehicle engine, wherein an oil seal coacts between a stationary casing and a rotatable shaft which projects through the casing. The oil seal apparatus includes an annular elastomeric seal member having a pair of axially spaced annular lip portions disposed for engagement with the shaft. One lip portion is positioned innermost for creating an oil seal, and the other lip portion is positioned outermost for creating a dust seal. This other lip portion is provided with a auxiliary annular lip which projects axially outwardly along the shaft. The auxiliary lip has an annular groove around its periphery to facilitate transfer of water around the seal member and prevent the water from flowing axially inwardly along the shaft past the dust seal.

摘要： A rolling bearing has a sensor unit disposed on one of the opposite circumferential surfaces of a fixed ring of the bearing. The sensor unit includes two strain gauges disposed on the circumferential surface of the fixed ring, one strain gauge extending in the circumferential direction fo the fixed ring and the other strain gauge extending in the axial direction of the fixed ring. Preferably the strain gauges are arranged to overlap with each other and to cross at right angles or obliquely to each other. A plurality of performance characteristics of the bearing are detected on the basis of output signals from the two strain gauges. The detection of the performance characteristics enables the rolling bearing to be monitored during operation with respect to applied load, the rotational speed and acceleration of a rolling ring thereof, a rise in temperature thereof and an abnormal vibration thereof.

摘要： A vehicle steering column is comprised of a lower column mounted to undergo angular displacement around one end portion thereof and an upper column telescopically connected to the other end portion of the lower column to undergo angular displacement together with the lower column and linear displacement relative to the lower column along a column axis. A plurality of ball members are disposed between the lower and upper columns for restraining free linear displacement of the upper column to thereby allow the upper column to undergo frictional linear displacement in response to the application of a given amount of force to the upper column. A support member is engaged with the upper column for restraining free angular displacement of the upper column to thereby allow the upper column to undergo stepwise angular displacement in response to the application of a given amount of force to the upper column.
