  • Patent number: 9934799
    Abstract: A bearing device includes a shaft and a roller bearing externally inserted over the shaft. The roller bearing includes an inner ring disposed coaxially with a center axis of the shaft, an outer ring surrounding the inner ring from an outer side in a radial direction, and a plurality of rolling elements held between the inner ring and the outer ring to be capable of rolling. The inner ring is divided into one half section and the other half section. The one half section contacts the rolling elements from the one side toward the other side in the axial direction, and the other half section contacts the rolling elements from the other side toward the one side in the axial direction. Preloads are applied to the two half sections in directions in which the one half section and the other half section are brought close to each other.

  • Patent number: 9761381
    Abstract: A coin type (button type) electrochemical cell is configured of a negative electrode can configuring a negative electrode side and a positive electrode can configuring a positive electrode side. Then, the negative electrode can and the positive electrode can are formed of non-magnetic stainless steel which does not have magnetic properties due to plastic processing. Specifically, the negative electrode can and the positive electrode can are formed by using high manganese stainless steel or SUS305 having a high nickel (Ni) content. In this way, the negative electrode can and the positive electrode can are formed of non-magnetic stainless steel which maintains non-magnetic properties even after being processed into the shape of a coin, and thus it is possible to provide a non-magnetic electrochemical cell, and as a result thereof, it is possible to provide an electrochemical cell which is not affected even at the time of being arranged in the vicinity of a magnet.
