Title: Damage preventing structure for loading mechanism of disk drive device
Inventor: TAKISHIMA TAKASHI
IPC: F16H19/04
Filed: 1995-06-16
Abstract: PURPOSE: To prevent the damage of a pinion and a rack or other parts than a driving unit even at the time of keeping a driving motor driving by making the driving unit movable in the direction of separating the pinion from a tooth surface of the rack. CONSTITUTION: Keeping rotation of the driving motor 22 may happen in spite of a cartridge holder 14 positioned at a loading completing position or an ejecting position on account of failure of detecting sensors 34 and 36, In this case, a unit frame 200 is capable of turning around a rotary hole in the direction of separation in the CC direction. By turning this frame 200, the pinion 27 is moved in tone direction of separating from the tooth surface of the rack 30 without changing the intermeshing state among an intermediate gear train 26, a worm wheel 25, a worm 24 and the motor 22. Thus, by moving the pinion 27 in the direction of separating from the tooth surface of the rack 30, interference of the pinion 27 under rotation with the teeth of the rack 30 under stoppage is evaded, and the pinion 27, the rack 30 and other parts than the driving unit are prevented from being damaged.

IPC: G01B11/30
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a defect inspecting device for highly precisely detecting a defect generated in an object to be inspected. SOLUTION: A first main control part 12 generates the distribution within a wafer face of reflectivity, and generates irradiating light control data D6 based on this. The irradiating light control data D6 are obtained as control data for adjusting the intensity of an irradiating light L2 so that the intensity of a reflected light L3 can be set as a mean value in all parts within the wafer face. A filter controlling part 14 inputs a filter control signal S2 to a filter 5 based on the irradiating light control data D6. The permeability or reflectivity of an irradiating light L1 in the filter 5 is controlled by a filter control signal S2. Thus, the intensity of a reflected light L4 from a wafer 1 to be inspected can be uniformly controlled within the wafer face.
