  • Patent number: 8532879
    Abstract: An information providing device includes: a vehicle condition detector for detecting a vehicle condition; a support information generating element for generating support information for a driver; and a tactile sensibility notification element in a steering wheel for notifying the support information to the driver. The steering wheel includes a wheel element having a base, a movable portion and a driving unit. The movable portion is relatively movable with respect to the base. The driving unit drives the movable portion according to the support information. The movable portion and the driving unit provide the tactile sensibility notification element. Movement of the movable portion provides notification of the support information.

  • Patent number: 4945231
    Abstract: In the compound rotary encoder of this invention, an absolute signal representing the upper m bits of a rotation angle signal, and an icreametal signal used for detecting the lower bits of the rotation angle signal are detected to obtain more detailed rotation angle information. Moreover, the rotation angle obtained by counting the increamental signal closely matches that obtained from the absolute signal, assuring the detection of the rotation angle with high resolution and precision. Since a rotating disk has only m bits of absolute code pattern, the rotary encoder can be small. This permits the absolute code pattern to have greater diametrical width so that a large output of the absolute signal can be stably obtained. On the other hand, the number of rotations can be obtained by counting and compensating a standard position signals. Since the rotary disk has the patterns both for detecting the standard position signal and for detecting the rotation angle, this too allows the rotary encoder to be small.

  • Patent number: 4541351
    Abstract: In pantyhose hip portion seaming operation, the open ends of a pair of stockings mounted respectively on upper and lower templates of a template unit are detected by means of phototubes to allow the both ends to be automatically positioned so that they are properly aligned.After a pair of stockings are mounted on the upper and lower templates of a template unit, a pair of phototubes arranged in upper and lower positions are moved to the ends of the stockings in such a way that upon one of the stocking ends being detected by one of the phototubes, the one phototube is caused to stop moving, the other phototube is caused to detect the presence of the other stocking.According to the condition of the other stocking as detected by the other phototube, the other stocking is moved forward or backward as required, and upon the end of the other stocking being detected by the other phototube, the hose is caused to stop moving, whereby the ends of the both stockings are properly aligned.
