  • Patent number: 11486458
    Abstract: A brake-side clutch part includes an outer ring whose rotation is restricted and an output shaft from which rotation is output. The outer ring is provided with a slide gear that meshes with the output shaft when rotational torque is cut off and releases a meshing state with the output shaft when rotational torque is transmitted. The output shaft is provided with an inner gear that meshes with the slide gear so as to be slightly rotatable. An alignment part that aligns a phase of the inner gear with that of the slide gear when rotational torque is cut off, and a centering part that returns the inner gear to a neutral position with respect to the output shaft when rotational torque is transmitted are provided between the inner gear and the output shaft.

  • Patent number: 10258702
    Abstract: A water-absorbent carrier for moist heat sterilization can be used in a narrow space and does not have a risk of generating foreign matter. The water-absorbent carrier is obtained by embedding a water-absorbent substance in a synthetic resin. The water-absorbent carrier can be manufactured by impregnating the water-absorbent substance with a water-soluble substance, drying the water-absorbent substance, embedding the water-absorbent substance in a thermoplastic synthetic resin, and washing the water-absorbent substance to remove the water-soluble substance. Alternatively, the water-absorbent carrier can be manufactured by dispersing a water-insoluble synthetic resin in a dispersion medium, mixing the water-absorbent substance in the dispersion medium, pouring the mixture into a mold, and volatilizing the dispersion medium. A medical article to be sterilized includes the water-absorbent carrier packaged in a closed space.

  • Patent number: 9859185
    Abstract: A semiconductor packaging structure includes a copper heat-sink with a shim projection which provides a stress release structure. The heat-sink with the shim projection may be used in conjunction with a pedestal in order to further reduce the thermal stress produced from the mismatch of thermal properties between the copper heat-sink metal and the ceramic frame. The copper heat-sink with a shim projection may also be part of the semiconductor package along with a lead frame, the ceramic frame, a semiconductor device, a capacitor, a wire bond and a ceramic lid or an encapsulation. The copper heat-sink, the ceramic frame and the lead frame are all chosen to be cost effective, and chosen such that the packaging process for the semiconductor device is able to achieve a smaller size while maintaining high reliability, low cost, and suitability for volume manufacturing.

  • Publication number: 20170237564
    Abstract: The event of [Probability that the two-parts-become-one]=1.0 is “Two-parts-are-one password”. The event of probability<<1.0 is “Two-parts-are-not-one password”. Even if a password of the service side leaks, it is harmless. The maintenance cost of the password is unnecessary. There exists the decomposition point of responsibility within “Two-parts-are-one password” itself so that it becomes disadvantageous to bring up a lawsuit. No password file and no password backup required in an authentication server segment. The core that has produced these innovative effects is the implementation of Split Knowledge and Dual Control of an active key data; it satisfies PCI DSS version 1.2.1 for the first time in the world.
