Abstract: A work spindle device having a rotor which allows a workpiece to be fed and ejected quickly and permits the workpiece to be machined simultaneously at opposite ends thereof. A clamp member having collets on opposite ends and a central axial through hole for insertion of the workpiece therein is disposed in the rotor. Each of the collets is insertable in one of a pair of tapered holes defined in the rotor so as to be pitted therein. A spring means normally urges the collets and the corresponding tapered holes into interfitting engagement for clamping the workpiece in the rotor. The work spindle device also has a mechanism for releasing the collets and the tapered holes from their interfitting engagement to unclamp the workpiece from the rotor.

Abstract: A steering system for a vehicle with front and rear wheels suspended from a vehicle body through a suspending mechanism, comprising a front wheel steering mechanism for steering the front wheels at an angle in accordance with a steering operation of a driver, and a rear wheel steering mechanism for steering the rear wheels at an angle in accordance with a travelling state of the vehicle. The rear wheel steering mechanism has an arrangement for determining a steered angle correction quantity of the rear wheels in correspondence with a cushioning state of the wheel suspending mechanism, and an arrangement for specifying the steering angle of the rear wheels in accordance with the steered angle correction quantity.The cushioning state may be ascertained by detecting a cushioning stroke of the suspending mechanism or a roll angle of the vehicle.

Abstract: A steering system for a vehicle having a steerable front wheel (5) and a steerable rear wheel (11), in which the rear wheel is steered in accordance with a travelling state quantity (.alpha., .nu.) substantially influenced by a disturbance from outside of the vehicle and a vehicle speed (V) of the vehicle.

Abstract: A curvilinear measuring device having a base plate containing a retaining tapered track in which a slide member moves. On top of the slide member is a digital readout device with a lit LCD on top. The slide device can be removed in turn end for end for making concave measurements. A contact ball moves along the track and electronically changes the voltage which is digitally displayed.

Abstract: A steering system for vehicles comprising a steering wheel, a front steering sub-system including a drive pinion interlocked to be rotatable with the steering wheel, a rack shaft having a first rack engaged with the drive pinion and a second rack separated from the first rack, and a driven pinion engaged with the second rack; and a rear steering sub-system including an input shaft operatively connected to the driven pinion, an off-centered pin provided at one end of the input shaft, a pair of rear tie-rods adapted each respectively to turn either of the rear wheels, and a joint member relatively rotatably connected to the off-centered pin and both of the rear tie-rods. The joint member has a longitudinal axis thereof extending transversely of the vehicle. The axis of the off-centered pin is located substantially on the longitudinal axis. The rear tie-rods are connected to the joint member substantially on the longitudinal axis substantially at the same level as the axis of the off-centered pin.

Abstract: Two master sets of seven seventh cut cards having labels denoting major grocery categories thereon. Fourteen subsets of physically smaller cards. Each subset has seven seventh cut cards with labels denoting grocery subcategories and each subset being related to one major card. In a given set each master card may be a different color. The subset cards are preferably the same color as the associated master card.One set of master cards and associated subset cards may be placed in one pocket of a purse and the other cards in another other pocket of the same purse.

Abstract: An apparatus for bending a glass sheet has at least a lower mold, a conveyor device for conveying the heated glass sheet to a prescribed position over the lower mold, and a plurality of rolls for supporting the glass sheet in the prescribed position. A method of bending a glass sheet is carried out by utilizing the apparatus. The apparatus also includes a device for lowering the rolls to a position below the shaping surface of the lower mold, and an arrangement in the lower mold for accommodating the rolls which have been lowered. The apparatus may additionally have an upper mold coacting with the lower mold. The method comprises the steps of lowering the rolls below the shaping surface of the lower mold, transferring the glass sheet from the rolls onto the shaping surface of the lower mold while the rolls are lowered, and bending the glass sheet into conformity with the shaping surface of the lower mold under gravitational forces.

Abstract: A frame material for a motor vehicle comprising a structure having an elongated hollow body of a rectangular cross section and a honeycomb member having a multiplicity of independent chambers and arranged in the hollow body such that central axes of the chambers are directed substantially perpendicularly to longer sides of the rectangular cross section of the hollow body. A frame construction for use in a motor vehicle includes the frame material as a main frame interconnecting a head pipe and a rear fork pivot rectilinearly in side elevation.

Abstract: A motor vehicle including a vehicle body, a front road wheel disposed in the front part of the vehicle body, a rear road wheel disposed in the rear part of the vehicle body, an engine for driving at least either of the front and rear road wheels, and a steering wheel for steering at least either of the front and rear road wheels. To facilitate the steering operation, the motor vehicle is improved by means of a transverse sliding angle detection system for detecting the transverse sliding angle of the vehicle body, and a moving direction display unit for visually displaying the moving direction of the vehicle body on the basis of an output of the transverse sliding angle detection system.

Abstract: A steering system for a vehicle having a steering wheel and front and rear wheels, including a front steering sub-system for steering the front wheels in accordance with the steering angle of the steering wheel and a rear steering sub-system for steering the rear wheels in the same and opposite directions with respect to the front wheels in accordance with the steering angle of the steering wheel. The steering system is provided with a rack and pinion type variable-ratio mechanism for varying the ratio of the steered angle of at least either of the front or rear wheels to the steering angle of the steering wheel in accordance with the magnitude of the steering angle of the steering wheel. The design freedom in setting a functional relation between the steering angle of the steering wheel and the turning curvature of the vehicle is thus maximized.
