    摘要: In an evaluation apparatus of a hub unit, a signal processing unit outputs frequency analysis signals which indicate such a result obtained by that an output signal of an acceleration sensor fixed on a hub unit by a magnet is processed via an A/D converting unit and an envelope detecting unit, and thereafter, the processed sensor signal is analyzed for a frequency analysis by an FFT unit. Then, an evaluation output unit evaluates damage conditions of the hub unit based upon signal strengths of specific frequencies, and overall values, which are acquired from the frequency analysis signals, and then, outputs the evaluated damage condition to a display unit.

    摘要: A polishing method can process and flatten, in a practical processing time and with high surface accuracy, a surface of a substrate of a Ga element-containing compound semiconductor. The polishing method includes: bringing a Ga element-containing compound semiconductor substrate (16) into contact with a polishing tool (10) in the presence of a processing solution (14) comprising a neutral pH buffer solution containing Ga ions; irradiating a surface of the substrate with light or applying a bias potential to the substrate, or applying a bias potential to the substrate while irradiating the surface of the substrate with light, thereby forming Ga oxide (16a) on the surface of the substrate; and simultaneously moving the substrate and the polishing tool relative to each other to polish and remove the Ga oxide formed on the surface of the substrate.

    摘要: A bearing apparatus includes: two split outer ring halves which includes outer ring raceway surfaces and are disposed within a supporting hole of the housing, respectively; and a plurality of rollers which are disposed on respective inner surfaces of the both split outer ring halves and supports a shaft. Each of the two split outer ring halves includes an oil hole penetrating the split outer ring half in a radial direction thereof and an oil groove formed on an outer diameter surface of the split outer ring half along a circumferential direction thereof to allow the oiling passage and the oil holes to communicate with each other. Each of the oil holes is disposed at a position located at an angle of within 45° from the joint surface of the split outer ring halves in an opposite direction to a rotating direction of the shaft.

    摘要: A bearing apparatus includes two split outer ring halves disposed in close contact with each other and a plurality of rollers. A circumferential end of each of the split outer ring halves has a concave-and-convex shape including a first slope portion inclined with respect to a line extending along an axial direction of the split outer ring halves and a second slope portion inclined in an opposite direction to that of the first slope portion. Each of the rollers is provided with crowning so as to be shaped in barrel form, and an amount of crowning is set such that an apex of a projecting portion at the concave-and-convex shape of each of the split outer ring halves is located on an axially outer side of a rolling surface of the roller rolling on an inner peripheral surface of each of the split outer ring halves.

    摘要: A high frequency heating device having a switching member screwed into a screw hole formed in a flange and fixed to the exterior. When the exterior is fixed to the body, a through-hole formed at that portion in the rear plate of the body through which the switching member passes is too large for the switching member. Thus, while the switching member is fixable to the exterior, the switching member cannot be fixed to the body onto which the exterior is not mounted. Therefore, a high frequency heating device can be provided, wherein an exterior switch more surely keeps the power supply circuit open when the exterior is removed.
