Title: Method of making a games racket
Inventor: HEINS ROBERT C
IPC: A63B49/10
Filed: 1986-01-15
Granted: 1991-03-07
Abstract: The invention relates to hollow frames for games rackets e.g. for squash and badminton, which are in the form of hollow injection mouldings of thermoplastics material and to a method of making such frames involving injecting the thermoplastics material around a fusible core that can be subsequently melted out. For rackets such as for squash and badminton with relatively long thin shafts undesirable displacement of the shaft portions (22) of the core under moulding pressure is avoided by use of locating means (24A, 25A) that form holes that do not weaken the eventual shaft (23). The means are positioned to correspond to the neutral surface of the shaft and such that the greatest unclamped length of shaft core between supports divided by the depth of the shaft core is less than 10.

Inventor: STOL KURT
IPC: G05B19/414
Filed: 1986-08-28
Granted: 1990-05-08
Abstract: The method uses a programmable memory which allows a machine system e.g. industrial robot, to be taken through a specific sequence in a learning cycle.

Abstract: A method for removing residues in manufacturing semiconductor device compirses (A) forming phtoresist pattern on patterned layer of semiconductor substrate, (B) generating undercut and  residues, (C) doping  with  polymer,  (D)  forming  sidewall   polymer   on undercut-generated  pattern,  (E)  removing  residues,   and   (F) completing  prescribed  pattern.  Patterned  layer  is  formed  by growing or depositing polycrystalline silicon, nitride,  oxide  or metal. The polymer used has higher etching selectivity  than  that of photoresist. The sidewall polymer is formed by etching back.
