Abstract: There is provided an abrasive recovery device and an abrasive recovery method capable of recovering a slurry which is condensed until a concentration of its abrasive becomes high while suppressing an increase in pressure loss and a great decrease in a recovery ratio ascribable to membrane clogging. The abrasive recovery device is a device 1 which recovers an abrasive from a used polishing slurry which has been used in a CMP process, the device including a separation membrane 41 having a cylindrical hole passage to which the used polishing slurry is led, wherein an effective filtration part of the hole passage of the separation membrane 41 has a 0.8 m length or less, and the abrasive recovery device 1 condenses the used polishing slurry until a concentration of the abrasive becomes 10 mass % or more.

Abstract: A vehicle such as straddle type suitable for running on a rough has a front wheel, which is steered, disposed in front of a vehicle body frame and a rear wheel disposed to the rear side thereof. Such vehicle is provided with a vehicle body frame structure which comprises a front frame unit, a center frame unit, and a rear frame unit. These front and center and rear frame units are first assembled individually as a unit and then coupled together integrally as a vehicle body frame structure.
