  • Patent number: 8567364
    Abstract: A starter for an engine is equipped with a planetary gear speed reducer, a restraining mechanism, and a shock absorber which is made up of a rotary disc, a stationary disc, a case, and a load applying mechanism. The load applying mechanism applies a load to the stationary and rotary discs to develop a given degree of friction therebetween. When an excessive torque acts on the rotary disc through the internal gear, the shock absorber induces the rotary disc to rotate against the given degree of friction to absorb the torque to eliminate a physical impact to be exerted on the planetary gear speed reducer. The restraining mechanism restrains the load applying mechanism from moving in a radius direction of the internal thread to avoid undesirable engagement of the load applying mechanism with the internal thread, thereby ensuring the stability in applying the load to the stationary and rotary discs.

  • Patent number: 7980150
    Abstract: A starter includes a motor, a pinion, a pinion carrier carrying the pinion, a ring member provided on the pinion carrier, a shifting member, and a lubricant blocking member. The ring member is rotatable relative to the pinion carrier and restricted in axial movement toward the pinion. The shifting member has a ring portion that is arranged on the pinion carrier with the ring member interposed between the ring portion and the pinion. The ring portion has an axial end face that has a recess for receiving lubricant and is covered by the ring member. The shifting member is configured to shift, by pushing the ring member with the ring portion, the pinion in the axial direction, thereby bringing the pinion into mesh with a ring gear of an engine. The lubricant blocking member blocks the lubricant from being scattered due to rotation of the pinion carrier with the pinion.

  • Patent number: 7867567
    Abstract: In an aspect of the coating method according to the present invention, the lower limit decompression degree PS1 at which a seam trouble occurs is obtained from the formula of the viscocapillary model. According to the aspect of the present invention, coating is performed by setting the Pb so as to satisfy PS1<P0?Pb?PS1+0.2, and therefore, stepped unevenness can be effectively suppressed so that a seam trouble does not occur. It goes without saying that the aspect of the present invention can be applied to high viscosity/thick film coating, but it is effective especially in the case where a coating solution with low viscosity (for example, 0.005 Pa·s or lower) is coated to be an ultra-thin film (for example, 10 ?m or less in the wet film thickness) where stepped unevenness easily occurs.

  • Patent number: 7859161
    Abstract: The rotational electric machine includes a cylindrical yoke and a field winding connected to an inner surface of the cylindrical yoke. The field winding is composed of plural formed coils, each coupled to a bobbin. The bobbin includes a first flange for insulating the formed coil from the inner surface of the cylindrical yoke, a second flange for insulating the formed coil from a supporting brim of a pole core and a pipe portion for insulating the formed coil from a boss portion of the pole core. The first flange is made all around the pipe portion while the second flange is formed to extend only in the lateral direction of the pipe portion. The bobbin is easily coupled to the formed coil by flexibly bending the bobbin. Alternatively, the bobbin or bobbins may be made by folding a bobbin sheet after placing the formed coils on the bobbin sheet.
