Abstract: A component for a plasma processing apparatus, and a plasma processing apparatus are highly resistant to plasma and are highly durable. The component includes a substrate containing a first element that is a metal element or a semimetal element, and a film located on the substrate and containing yttrium oxide as a main constituent. The film contains yttrium oxide crystal grains oriented with a deviation angle of ±10° from a {111} direction of a crystal lattice plane of yttrium oxide. The yttrium oxide crystal grains oriented with the deviation angle have an area ratio of 45% or greater.

Abstract: An information processing device has a control unit that acquires information relating to a fluctuation of power consumed by an electrical product operating around a user, and that estimates a product consumed by the user and a consumption quantity of the product based on the information relating to the fluctuation in the power.

Abstract: A rolling bearing unit with a rotation speed detection instrument having a hub with a plurality of inner race tracks, an outer race formed of steel material with a plurality of outer race tracks, rolling elements between the tracks, and encoder on the hub and a sensor supported in a mounting hole in the outer race. A hardened layer is formed on the inner surface of the outer race and each portion where the outer race tracks are formed. An area of the inner surface around the mounting hole is not hardened.

Abstract: In a sealed thrust bearing providing a case which is formed of a corrosion resisting material and fixedly fitted to an outer race, an outer seal ring which is fixedly fitted to the outer peripheral edge of an inner race, and an inner seal ring which is fixedly fitted to an inner flange, the outer peripheral edge of a first outer seal lip forming the outer seal ring is slidingly contacted with the inner peripheral surface of the outer cylindrical portion of the case. The end edge of a first inner seal lip forming the inner seal ring is slidingly contacted with the flat portion of the case. In the inner peripheral edge of the flat portion, an inner cylindrical portion is so formed as to cover the sliding contact portion between the end edge of the first inner seal lip. The sealed thrust bearing can prevent the sliding contact portions thereof from being worn greatly even if rain, mud or the like splash on them.

Abstract: A pack seal apparatus formed with a first rigid ring having a radial leg portion and an axial leg portion in an L-shaped cross section, a second rigid ring having a radial leg portion and an axial leg portion in an L-shaped cross section, the first and second rings being coaxially arranged to be rotatable with respect to each other, a first elastic annular seal member secured to the radial leg portion of the first ring so as to be sealingly and slidingly engaged with the axial leg portion of the second ring, a second elastic annular seal member secured to the radial leg portion of the second ring so as to be sealingly and slidingly engaged with the axial leg portion of the first ring; the axial and radial leg portions of the first ring, the axial and radial leg portions of the second ring, and the first and second elastic annular seal members cooperating to define a closed annular space, and a pulser ring made of a separate thin metal plate mounted on the radial leg portion of one of the first and second ring

Abstract: A rolling bearing unit for sensing rotational speed has a synthetic resin connector to which a plug is connected to output a signal from a senser, and a metal cover lot supporting and protecting the connector.

Abstract: A bearing having a passive pulser ring which is provided axially adjacent to the frame substantially L-shaped in cross section, specifically the radially extending flange support section, and the cylindrical support section is provided between the outer and inner rings to provide precise parallelism and axial positioning.
