Patent GB-815675-A (GB)
Title: Improvements to the methods for the preparation of single crystals of semi-conducting substances
IPC: C30B15/04
Filed: 1957-03-22
Abstract: A single crystal having a PN junction is produced by withdrawing a seed crystal from a semi-conductor melt of one conductivity type, introducing the impurity characteristic of the opposite conductivity type, the growth process being stopped during the introduction and for a period long enough to allow for uniform distribution in the melt.  During the growth stoppage period the temperature of the melt may be raised slightly.  The process may be repeated to provide an intermediate layer of one conductivity type between two layers of the opposite conductivity type.  Alternatively the third zone after the intermediate zone of opposite conductivity type, may be produced by merely adding the appropriate impurity to the melt without interrupting the growth process or raising the temperature.  The withdrawing of the crystal, temperature and addition of impurity processes may be controlled automatically by a perforated tape. Germanium and silicon are mentioned as suitable materials.

Patent ID-19758-A (ID)
Inventor: MOWRER NORMAN R
IPC: C08G59/14
Filed: 1997-10-06
Abstract: Epoxy-polysiloxane polymer compositions of this invention are prepared by combining a resin component with a hardener component. The resin component comprises a non-aromatic epoxy resin ingredient and a polysiloxyne ingredient. The hardener component comprises an amine and optionally an organotin catalyst. The composition can also include aggregates, pigments and other additives depending on the particular end user. The composition is prepared using a sufficient amount of water to promote hydrolysis of the polysiloxane and the polycondensation of the silanols produced by such hydrolysis. In its cured form, the epoxy-polysiloxane composition exists as a uniformly dispersed arrangement of linear epoxy chain fragments that are cross-linked with a continuous polysiloxane polymer chain, thereby forming a non-interpenetrating polymer network chemical structure that has substantial advantages over conventional epoxy systems. Protective coatings forming from such compositions exhibit excellent weatherability in sunlight, and superior chemical and corrosion resistance after curing.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of manufacturing processes of a transmission wheel. SOLUTION: A second transmission wheel 100 is constituted of two bodies of a gear 1 and a pinion 2. A hole section 12 for assembling the pinion 2 is drilled through the central part of the gear 1 and two chord-like stopping sections 13 are provided to the hole section 12. The chord lengths of the stopping sections 13 are nearly equal to the interval between two adjacent teeth 21 of the pinion 2. At the time of fitting the pinion 2 in the gear 1, two adjacent teeth 21 and 21 of the gear 13 are positioned to both sides of each stopping section 13. Therefore, the relative rotation between the gear 1 and pinion 2 in the peripheral direction can be suppressed by engaging the teeth 21 and 21 of the pinion 2 with the stopping sections 13 even when no notch is provided to the pinion 2.
