Abstract: A relay device (30) receives a standard radio wave transmitted from a transmitting station (10) and containing time data, i.e. a time code. The device (30) transmits a relayed radio wave containing the time code received, at a first intensity. When the device (30) receives a transmission command code transmitted from a time-data receiving apparatus (50), it transmits the relayed radio wave for a predetermined time (10 minutes) at a second intensity that is lower than the first intensity. When a time-correction switch is operated, the time-data receiving apparatus (50) transmits a transmission command code to the relay device (30). The time-data receiving apparatus (50) receives the relayed radio wave transmitted at the second intensity from the relay device (30) in response to the command code and corrects the time on the basis of the time code it has received.

Abstract: A radially mounted disk brake has a caliper body secured to a support member secured to a vehicle body. The caliper body has mounting holes extending in a direction perpendicular to the axis of rotation of a disk rotor. Large-diameter hole portions are formed at the openings of the mounting holes on the side thereof closer to the support member.

Abstract: A shift control apparatus is arranged to effect a shift in an automatic transmission by changeover of friction elements to be engaged with disengagement of a disengagement-side friction element and engagement of an engagement-side friction element. A shift controller is configured to detect an end of a loss stroke in the engagement-side friction element, and performs an operation to decrease the disengagement-side working oil pressure at a set gradient and to increase the engagement-side working oil pressure at a predetermined gradient upon detection of the end of the loss stroke in the engagement-side friction element. The predetermined gradient of the engagement-side working oil pressure for the engagement-side friction element is made lower for a low engine load than for a high engine load.
