Abstract: A disc rotor includes a sliding portion, a hat portion, and a connecting unit connecting the sliding portion and the hat portion. The connecting unit includes a washer arranged between the radially inner portion of the sliding portion and the radially outer portion of the hat portion, and a connecting pin having a head portion, having a shaft portion inserted through a first through-hole formed at the sliding portion, the washer and a second through-hole formed at the hat portion in an axial direction of the rotor, and riveted at an end portion of the shaft portion so as to integrally fasten the sliding portion, the washer and the hat portion. A riveted portion of the connecting pin is formed into a taper shape, and an outer circumferential surface of the riveted portion contacts and engages a tapered surface formed at the second through-hole of the hat portion.

Abstract: A ventilated disc rotor includes a hat portion at which the ventilated disc rotor is attached to a rotation shaft, a sliding portion formed in an annular shape and provided at a radially outer portion of the hat portion, the ventilated disc rotor being slidably held by an inner pad and an outer pad at the sliding portion so as to brake a rotation of the ventilated disc rotor and the sliding portion including an inner disc-shaped portion, an outer disc-shaped portion and a plurality of cooling fins, wherein the hat portion and the plurality of cooling fins are integrally made of a steel plate material, and the outer disc-shaped portion and the inner disc-shaped portion are formed by casting together with the plurality of cooling fins in such a way that the plurality of cooling fins integrally connects the inner disc-shaped portion to the outer disc-shaped portion.

Abstract: A ventilated disk rotor includes a pair of opposed annular sliding plates, a plurality of ribs and a plurality of ventilation holes. The ribs extend between the pair of the annular sliding plates. The plurality of ventilation holes are formed between the plurality of ribs. In addition a groove is positioned substantially at the center of the outer circumferential end or inner circumferential end of at least one of the plurality of ribs.

Abstract: Pharmaceutical compositions containing a benzoxazole compound and a 2,3-dihydrobenzofuran compound represented by the following formula (I) and its pharmaceutically acceptable salt: ##STR1## In the formula, any one of P, Q, R and S is a group represented by the formula: ##STR2## and R.sub.1, R.sub.2 and the reining three substituents out of the substituents P to S each independently stand for various substituents. These compositions are used as an ATCAT inhibitor or for treating hyperlipidemia and atherosclerosis.
