A vehicle wheel bearing apparatus has a wheel hub integrally formed with a peripheral wheel mounting flange at one end and a double row rolling bearing. The double row rolling bearing has an outer member integrally formed with a peripheral body mounting flange and with double row outer raceway surfaces. An inner member, including the wheel hub, is formed with double row inner raceway surfaces each arranged opposite to each of the double row outer surfaces. Double row rolling elements are freely rotatably contained between the double row outer and inner raceway surfaces. The double row rolling bearing is adapted to receive a predetermined preload. A separate outer or inner ring is arranged on at least one of the outer or inner members. A preload varying mechanism is arranged at an abutting portion between the outer and inner members to vary the preload applied to the bearing. The preload varying mechanism can be extended or contracted based on an output signal from a detecting sensor to detect the vehicle running conditions.

A ferrule includes a body having a cylindrical shape. Elastic gripping portions are arranged on the body so as to bulge radially inwardly. The elastic gripping portions can have elastic contact with the outer circumferential surface of a glass tube. The body of the ferrule is mounted to the glass tube via the elastic gripping portions capable of elastic and radial deformation. Thereby, the variations in outer diameter of the glass tube can be absorbed, and therefore the dimensional control with high precision is not required for glass tubes at the time of manufacturing. This leads to cost reduction.

The present invention is a television receiver, including a counter which measures a time period for which the television receiver continuously operates, an evaluator which determines whether the time period is more than a predetermined time period and a controller which adjusts a brightness value of a picture to more than a predetermined value when the time period is more than the predetermined time period.

Discharge tubes, each of which includes a glass tube and a ferrule that has a substantially cylindrical shape and is fitted to each end portion of the glass tube, are supported by a plurality of pairs of relay connectors (or supporting members) provided on the front side of a chassis having substantially a plate-shaped configuration. When a discharge tube is supported by relay connectors, stoppers provided on the relay connectors lock the ferrules so that axial movement of the discharge tube relative to the relay connectors is restricted.

A bearing device for a wheel, where preload control is easy and a uniform amount of preload can be applied even if a bearing seal is installed in the bearing device. The bearing device rotatably supports a wheel and has an outer member 1, an inner member 2, and rolling elements 3 interposed between both members. The outer member 1 has on its outer periphery a vehicle body installation flange 1a, and double row rolling surfaces 6, 7 are formed on the inner peripheries of the outer member. Rolling surfaces 8, 9 facing the rolling surfaces 6, 7 of the outer member 1 are formed in the inner member 2. Between the rolling surfaces of both members 1, 2 are interposed the rolling elements 3. A sensor 4 for detecting the amount of preload of the bearing is provided on either the outer member 1 or the inner member 2.

An object of the invention is to make a light source and a power supply line detachable easily so as to enable the light source to be replaced easily for maintenance. The invention provides a lighting device for a display, which includes a light source having electrode terminals provided at both ends thereof, connectors attached to the ends of a power supply line for supplying power to the light source, light source-holding chassis placed at the ends of the light source, and insertion portions opened in the chassis. The electrode terminals of the light source are placed inside the insertion portions, and the connectors are fitted detachably in the insertion portions from the outside, whereby the terminals in the connectors are connected to the electrode terminals.

In a backlight module, when relay connectors exposed to a back side of a chassis are engaged with the connector portions of a lighting jig, the power from the power supply source of the lighting jig is supplied to discharge tubes via the connector portions and the relay connectors. Thereby, the discharge tubes can be lighted, even if a power board is not connected to the relay connectors. At the time, the lighting jig is arranged to face the back surface of the chassis, and therefore optical sheets can be mounted to the chassis from the front side.

A rotation sensor assembly includes an encoder, mounted on one end of an inner member of a bearing, and a rotation sensor fitted to one end of an outer member of the bearing in face-to-face relation with the encoder. A cylindrical wall of a core metal of the encoder press-fitted onto the inner member has a cylindrical extension protruding axially outwardly from one end of the cylindrical wall. A displacement sensor assembly includes a pair of displacement sensors provided in face-to-face relation with the cylindrical extension and spaced equidistantly from each other in a circumferential direction. The rotation sensor is positioned between the displacement sensors in the circumferential direction.
