  • Publication number: 20210375613
    Abstract: In a method for manufacturing an SiC wafer, a work-affected layer removal step of removing a work-affected layer generated in a surface and inside of an SiC wafer is performed, so that the SiC wafer from which the work-affected layer is at least partially removed is manufactured. In the work-affected layer removal step, the SiC wafer having undergone a polishing step is etched with an etching amount of 10 ?m or less by being heated under Si vapor pressure so that the work-affected layer is removed. In the polishing step, an oxidizer is used to produce a reaction product in the SiC wafer while abrasive grains are used to remove the reaction product. In the SiC wafer having undergone the polishing step, an internal stress caused by the work-affected layer is present at a location inner than the work-affected layer, and an internal stress of the SiC wafer is reduced by removing the work-affected layer in the work-affected layer removal step.

  • Patent number: 5943795
    Abstract: A bicycle shoe is disclosed for use with a clipless pedal. The bicycle shoe has an upper peripheral portion with a sole portion coupled thereto and an inner sole portion or cushior overlying the inner surface of the sole portion. The bicycle shoe can either be designed for use with a road bicycle or a mountain bicycle. In other words, the sole portion can be either a substantially hard, rigid member or a substantially flexible, resilient member. In either case, the sole is provided with one or more attachment apertures for attaching a low profile cleat thereto. In particular, the attachment aperture or apertures are longitudinally arranged such that the fasteners which couple the cleat to the shoe sole portion is located in front of and behind the pedal shaft. Preferably, the attachment aperture or apertures is spaced from a center line extending between the center points of the toe portion and the heel portion of the sole.
