摘要： A wafer grinding method is disclosed, in which only a region, corresponding to a device formation region, of the back side of a wafer is ground in rough grinding conducted first, while the part surrounding the region thus ground is left unground as an annular projected part, to prevent the outer peripheral edge of the wafer from becoming knife edge-like in shape. In the subsequent finish grinding, the annular projected part is ground and, further, the whole area of the back side of the wafer is ground to be flat. Chippings of the outer peripheral edge may be generated only during the finish grinding, whereby the chippings are prevented from occurring or limited to minute ones.

摘要： A hydraulic damper has a first oil chamber, a second oil chamber, a communication mechanism defining a communication oil passage, the first and second oil chambers communicating with each other through the communication oil passage, and a damping force adjusting mechanism for varying a cross-sectional area of the communication oil passage to adjust damping forces. The damping force adjusting mechanism includes an adjusting rod having an end disposed in a portion of the communication oil passage, the adjusting rod being movable toward and away from the communication oil passage to vary the cross-sectional area of the communication oil passage, an eccentric cam rotatably disposed in engagement with an opposite end of the adjusting rod, and a rotary actuator for rotating the eccentric cam to move the adjusting rod toward and away from the communication oil passage to adjust the damping forces.
