    摘要: A spindle apparatus for supporting and rotating a workpiece in a grinder. The spindle apparatus includes a workpiece spindle rotatably supported on a spindle head and driven for rotation by a motor, and a spindle plate mounted to the front end of the workpiece spindle and including an eccentric drive pin. The workpiece spindle has a bore in which a ram is axially movable. A center is fit in the front end of the ram. A unit is provided to advance the ram to engage with one end of the workpiece when the workpiece is to be supported. A rotary sleeve is rotatably supported on the front end of the ram and includes an engagement portion which is displaceable in the axial direction of the spindle and engageable with the drive pin in the direction of rotation. A driving unit is mounted to the front of the rotary sleeve to engage the workpiece in the direction of rotation when the ram is in its advanced position to thereby transmit rotation.

    摘要: A method for truing a grinding wheel having a non-straight cylindrical grinding surface. In truing operation, a truing tool is caused to contact different portions of the grinding surface, and relative position of the truing tool is detected when the truing tool contacts the respective portions. Then, a first portion rom which a largest amount of abrasive layer must be removed, and a second portion from which a smallest amount of abrasive layer must be removed are found out. Based upon the detected positions, the radial location of an initial truing start position and a truing operation end position are calculated. The truing tool is initially moved to the initial truing start position, and then traversed from the truing start position along a locus corresponding to a desired final shape of the grinding wheel. The radial location of the truing start position is then shifted in a direction of approaching to the rotational axis of the grinding wheel, and the traverse movement is repeated. When the radial location of the truing start position reaches or exceeds the truing operation end position, the truing operation is stopped.

    摘要: A phase lock circuit includes a control signal generator which generates a control signal changing for every frame consisting of an odd-numbered field and an even-numbered field in a reproduction mode. The control signal has a first level for a frame and a second level for a subsequent frame. The phase lock circuit further includes a first PLL circuit and a second PLL circuit. The first PLL circuit generates a first synchronizing signal which is phase-locked with a reproduced synchronizing signal for every other frame when the control signal is at the first level. The second PLL circuit generates a second synchronizing signal which is phase-locked with the reproduced synchronizing signal for every other frame when the control signal is at the second level. Furthermore, the phase lock circuit includes a select circuit which selects one of the first and second synchronizing signals supplied from the first and second PLL circuits on the basis of the control signal. The selected synchronizing signal is the synchronizing signal output from the phase lock circuit.

    摘要: A wheel alignment control system for a vehicle having at least one pair of rear road wheels opposing each other in the transverse direction of the vehicle, for changing and setting a wheel alignment factor of the wheels in relation to a current speed of the vehicle. The wheel alignment factor to be set by the control system is a camber angle of the rear wheels, a static toeing angle of the rear wheels, or a dynamic toeing angle of the rear wheels. The dynamic toeing angle of changed to be set by changing a stroke characteristic of each of a pair of suspenion units respectively supporting the rear wheels, on which the stroke characteristic of an associated one of the suspension units exerts an effect such that, in accordance with a stroke length thereof, the toeing angle of a corresponding one of the rear wheels is varied.

    摘要: A steering system for a vehicle with a front wheel and a rear wheel, in which the rear wheel is steerable in relation to a steering operation of the front wheel, such that a ratio control of a steered angle ratio of the rear wheel to the front wheel is effected to be variable in accordance with a travelling speed of the vehicle. The steering system is provided with a mode selecting unit adapted to be manually operable for exclusively setting an arbitrary one of a plurality of control modes of the ratio control. The steering system may be further provided with a time-delay unit for gradually effecting the ratio control, when changing one of the control modes to another thereof.
