    • PURPOSE: To form a screw type forward end anti-backflow valve of a relatively low-cost nitralloy or a spring steel by almost or entirely eliminating a relative rotary motion between an forward end of a screw and a sealing ring in rotating the screw during a plasticizing operation. CONSTITUTION: An opening 60 having threads is provided at a forward end of a screw 14. And, a spot facing cylindrical surface 64 is provided its innermost side of the opening 60. A rod 66 has a cylindrical end 68 contained in the spot facing 64, and the other end externally extended, and mounted with a forward end 72 of the screw. Its end face has two pairs of arms 74 radially extended so that a flow passage of a plasticized material is formed between the adjacent arms. An annular retaining ring 76 is screwed into the opening 60 to prevent an outward movement of the rod 66. The rod 66 is rotatable. An annular sealing ring 80 is disposed between the ring 76 and a forward end 72 of the screw. Its front surface is brought into contact with a rear surface of the arm 74 of the forward end 72 of the screw. A rear part of the ring 80 is formed with a sealing surface 82. When it is brought into contact with a sealing surface 8 formed at a retaining ring 76, a flow between the surfaces 82 and 84 is prevented.

    • A robotic manipulator of the type having a plurality of serially connected drive shaft and a mounting surface (31) affixed to one end thereof comprises a first shaft (40) rotatable about a first axis (A-A) coincident with one ordinate of a mutually perpendicular triodinate system and a first housing (21b) rotatable about said first axis (A-A), a second shaft (27) rotatably mounted to said first shaft (40) for rotation about a second axis (B-B') oriented with respect to said first axis (A-A), and a second housing (21a) rotatable on the first housing (21b) about the second axis. Rotational movement is imparted to the second shafts (27) about said second axis (B-B) in accordance with the rotational movement of a shaft (42) rotatable about the first axis. A mounting surface (31) has a centerline angularly oriented with respect to the second shaft (27), and a third shaft (34) upon which the mounting surface (31) is attached is rotatable about a third axis (C-C) angularly oriented with respect to said second axis (B-B). An axis sharing cylinder (24) is substantially immovably mounted on the second housing (21a) parallel to said second axis (B-B), with such axis bearing cylinder extending partially inwardly in to the first housing and providing support for a gear cluster arrangement (50) substantially indenpendent of the first housing (21b). This arrangement produces a stiffer drive train, helps control backlash, and simplifies assembly.
