Title: Workpiece manipulator
Inventor: INAGAKI SHIGEMI
IPC: B25J15/00
Filed: 1980-06-30
Granted: 1983-10-25
Abstract: The manipulator for an industrial robot grips a work-piece with a pair of fingers(10,11). A ring-shaped member(18) such as a belt or chain, is stretched between a pair of rotatable pulleys(16,17). One of the fingers is coupled to one linear segment of the belt, and the other finger is coupled to the other linear segment of the belt. Because the two linear portions of the belt move by equivalent absolute amounts in mutually opposing directions, the finger can always be made to come together at the exact gripping center of the device. The drive mechanism has a cylinder(22) and piston(23). The piston is fixed and the cylinder is movable and connected to the belt.

Abstract: Cu alloy for electric and electronic  parts  is  composed  of 0.02- 0.6 wt.% Cr, 0.02-0.6% wt.% Ni, 0.005-0.20 wt.% Al, 0.01-0.06 wt.% P and the remainder of Cu. Cr has the advantages of promoting strength and annealing  resistance  property  in  the  composition ranges of 0.01  wt.%  and  above  but  it  has  disadvantages  of diminishing electrical conductivity and the additive effect of  Ni and P above 0.08 wt.%. The effect of Ni, P and Al on strength  and electrical conductivity is similar to Cr. In optimization  of  Cr, Ni, P and Al contents in  Cu  matrix,  its  tensile  strength  and ductility  can be  controlled  to  42-51  kgf/mm2  and  6.9-9.5%, respectively, its hardness  and  electrical  conductivity  can  be controlled to 118- 134 in HV and 86.5-95  in  IACS%,  respectively, and its annealing temperature can be controlled to 500-600  deg.C. The Cu alloy is used for a surface mounting IC and a transistor.

Abstract: A fiber reinforced golf shaft is  manufctured  by  forming  a partially reinforced layer on the  step  part  of  a  step-tapered steel mandrel by multi-laminating a carbon fiber reinforced resin, while the fiber orientationg angle is kept in the range  of  0- 45 degree, (B) successively laminating on the mandrel  a  bias  layer with the fiber orientation angle of   45  degree  and  a  straight layer with the fiber  orientation  angle  of  0  degree,  and  (C) winding  the  heat-shrinkable  tape  on  the  laminated   mandrel, followed by  heat-hardenin.  The  produced  golf  shaft  shows  an improved torsional property and much less weight.
