Abstract: PURPOSE: To improve gravel excavating property of grab bucket in such a way that grab bucket support frame is made extensible without regard to height of dumping operation, and that operation of grab bucket is made controllable without regard to extending movement of the support frame.  
     CONSTITUTION: Grab bucket support frame consisting of three frame sections 1, 2, and 3 can be extended by supplying pressure oil from supply pipe 8 through passage 10 into one of oil chambers of hydraulic cylinder 6. In this case, rope 15 extending from brackets 12a, 12b to sheaves 13a, 13b is elongated by the length equal to extended length of cylinder 6, whereas the part of rope 15 extending from sheaves 13a, 13b to sheave 14 is shortened by the identical length, that intermediate frame section 2 is extended with respect to base frame section 1 by the identical length, and simultaneously, end frame section 3 is also extended with respect to intermediate section 2 by the identical length. Since other hydraulic cylinders and operating rope are disposed independently for actuating grab bucket 4, excavating work by grab bucket 4 can be freely conducted regardless of extending operation of its support frame.

Filed: 1990-05-25
Abstract: PURPOSE:To slightly increase or decrease magnification which is determined unequivocally by adding an optical system which corrects the mask itself optically, using this mask and exposing resist to the pattern of the mask. CONSTITUTION:The mask 3 is equipped with a mask blank 5, the pattern 4 is formed on one main surface of this blank 5, and a Fresnel lens 6 as a lens for power correction is provided on the other main surface opposite from the main surface where the pattern 4 is formed in an abutting state and converges incident luminous flux slightly.

Consequently, the magnification of the transferred pattern can be varied about the unequivocally determined magnification without re-forming the mask 3 nor varying the power of the reduction lens 16 of the reduction projection and exposure device.
