摘要:
A wheel bearing device of the invention includes a flanged shaft member that includes a shaft portion to which a rolling bearing is assembled, a fitting shaft portion that is formed on one end side of the shaft portion and that is fitted to a center hole of a wheel, and a plurality of flange portions that extend radially outward on an outer peripheral surface located between the shaft portion and the fitting shaft portion and each of which has a bolt hole in which a hub bolt for fastening the wheel is arranged. Each flange portion is formed by side extrusion when a forged recess is formed at a center of an end surface of the fitting shaft portion by cold forging.

A wheel rolling bearing unit has a hub spindle having flange and shaft-shaped sections, an inner-ring raceway surface on the outer peripheral surface of the shaft-shaped section; an outer ring member disposed around the outer periphery of the shaft-shaped section, an outer-ring raceway surface on the inner peripheral surface thereof; and rolling elements between the inner-ring raceway and outer-ring raceway surfaces. The flange section is on one side of the spindle in a rotation axis direction thereof; on the flange surface, a cylindrical spigot joint section protruding on one side is coaxial with the spindle; the boundary section of the flange surface and the outer peripheral surface of the spigot joint section has an arc-shaped boundary surface to connect smoothly toward the flange surface. The surface roughness of the boundary surface is finer than that of the flange surface and the outer peripheral surface of the spigot joint section.

An image display device includes a housing including a front cabinet and a back cabinet. Inside the housing, arranged are a flat display panel, a speaker which emits voice forward, and a circuit board which displays an image on the flat display panel and transmits an audio signal to the speaker. Here, the flat display panel is attached to the front cabinet while the speaker and the circuit board are attached to the back cabinet. A sound emitting hole through which an acoustic wave from the speaker should pass is formed in at least a part of a region surrounding a display screen of the flat display panel on a front surface of the front cabinet, and the speaker has such a posture that a sound emitting surface thereof is inclined with respect to the display screen of the flat display panel and faces outside of the display screen.

A substrate processing apparatus comprises an indexer block, an anti-reflection film processing block, a resist film processing block, a development processing block, and an interface block. An exposure device is arranged adjacent to an interface block. The interface block comprises a drying processing group including two drying processing units and an interface transport mechanism. After a substrate is subjected to exposure processing by the exposure device, the substrate is transported to the drying processing units in the drying processing group by the interface transport mechanism, where the substrate is subjected to cleaning and drying processings.

An interface transport mechanism employs an upper hand during the transport of a substrate to an exposure device, and employs a lower hand during the transport of the substrate that has been carried out of the exposure device. A fifth central robot employs a lower hand during the transport of a substrate after the exposure processing by an exposure device, and employs an upper hand during the transport of a substrate after the drying processing that has been carried out of a drying processing group. That is, the upper hand is employed to transport a substrate to which no liquid is attached, and the lower hand is employed to transport a substrate to which a liquid is attached after the exposure processing.

摘要:
A rolling bearing such as a rolling bearing for an alternator of an automobile, the life period of which is prevented from being shortened due to the temporal reduction of a radial internal clearance even in a high temperature environment. The rolling bearing includes a plurality of rolling elements rotatably arranged between an inner race and an outer race, and at least the inner race and the outer race are made of a steel material. An austenite residual rate of the inner race is smaller than an austenite residual rate of the outer race. The amount of dimensional expansion of the outer race due to the martensite transformation of residual austenite is larger than that of the inner race, so that the occurrence of clearance loss is suppressed even when dimensional expansion of the rolling elements occurs.
