Abstract: A training operation may be performed by a memory controller to provide a system clock signal and a data clock signal having a desired temporal (e.g., phase) relationship to one another. The system clock and data clock signals may be provided to a memory. In some examples, the memory controller may provide a command to the memory to put the memory in a training mode. Once in the training mode, the memory controller may provide a write command and toggle the data clock signal a number of times. If the memory provides one output, the memory controller may adjust the relationship between the data clock and system clock signals. If the memory provides another output, the memory controller may maintain the relationship between the data clock and system clock signals and exit the training mode.

Abstract: A sensor-equipped structure of a vehicular-wheel bearing assembly mounted to an outer ring member of a vehicular-wheel bearing assembly, is provided with a sensor portion for detecting the rotation of an inner ring member rotatably disposed on a radially inner side of the outer ring member, and a cover formed of a metal. The sensor portion includes a sensor element for magnetically detecting the rotation of the inner ring member; a connector for supporting a terminal electrically connected with the sensor element; and a capacitor. The sensor portion is molded of a synthetic resin and unified with the cover. The cover has a through hole, the synthetic resin extends from an inner side of the cover through the through hole into the connector, the synthetic-resin is in contact with an inner surface of the cover and not in contact with a circumferential surface of the cover defining the through-hole.

Abstract: Balls are interposed between respective raceway surfaces of inner and outer ring members, and a seal apparatus is provided between shoulder portions of the inner and outer ring members. The seal apparatus comprises an outer ring-side seal ring fixed to the outer ring member, and an inner ring-side seal ring fixed to the inner ring member. A pulser ring is fixed to a ring-shaped core metal of the inner ring-side seal ring. In an outer diameter side of the ring-shaped core metal of the outer ring-side seal ring, a magnetic sensor is molded with resin by an external member to be integrated therein. A connector connected to the magnetic sensor is formed consecutive with the external member.

Abstract: [Problem] A cover is provided which is adapted to prevent the formation of cavities in a sensor portion thereby increasing a mounting strength of the sensor portion mounted to the cover and which permits the reduction of an axial dimension of a vehicular-wheel bearing assembly thereby increasing the degree of design freedom of the bearing assembly. [Means for solving the Problem] A sensor-equipped cover 1 for vehicular-wheel bearing assembly is mounted to an outer ring member 2 of a vehicular-wheel bearing assembly, is provided with a sensor portion 7 for detecting the rotation of an inner ring member 12 rotatably disposed on a radially inner side of the outer ring member 2 via rolling elements, and is formed of a metal. The sensor portion 7 includes: a sensor element 6 for magnetically detecting the rotation of the inner ring member 12 in non-contact manner; a connector 5 for supporting a terminal 4 electrically connected with the sensor element 6; and a capacitor 16.

Abstract: A rolling bearing device for a wheel includes: a hub wheel including a hub spindle to be assembled with a rolling bearing, a flange formed on the hub spindle, and a bolt hole formed through the flange; a hub bolt to be press-fitted in the bolt hole, in which hub bolt includes a shank formed with a serrated shank portion to press-fitted to bite the bolt hole, an intermediate shank portion and a threaded portion in this order; and an annular ridge formed on an inner circumference of an opening on a press-fit exit side of the bolt hole. The annular ridge have a diameter smaller than that of the bolt hole and comes into contact or close to the intermediate shank portion to clog the bolt hole.

Abstract: A seal apparatus comprises an outer ring side seal ring fixed to an outer ring member, and an inner ring side seal ring fixed to an inner ring member. A pulser ring is fixed to a ring shaped core metal of the inner ring side seal ring. On an outer diameter side of the ring shaped core metal of the outer ring side seal ring, a magnetic sensor is molded with resin by an external member to be integrated therewith. A connector connected to the magnetic sensor is successively formed with the external member. A reinforcing member which reinforces the sensor side connector is provided on at least either of the external member or the sensor side connector.
