Title: Improvements in semiconductor devices and methods of making same
IPC: H01L29/00
Filed: 1962-06-08
Abstract: 973,837. Semi-conductor devices. GENERAL ELECTRIC CO. June 8, 1962 [June 12, 1961], No. 22240/62. Heading H1K. A three electrode switching device has four main layers alternating in conductivity type and has ohmic electrodes on each of the two outer layers-a portion of one of the two outer junctions is made a tunnel junction and the third electrode is in ohmic contact either with the second layer of the structure if the degenerate region of the tunnel junction is of the same conductivity type as the outer (first) layer or with the degenerate region itself if this is of the same conductivity type as the second layer. The device shown in Fig. 1 is constructed from a three ohm cm. silicon wafer which has phosphorus diffused into its faces. The wafer is then heated in steam to grow a protective oxide film on its surface. That part of the surface under which layer 6 is to be formed is either protected from oxidation or has the oxide film subsequently etched off, and boron is diffused into the exposed surface of the wafer to form the P-type layer 6. The wafer surfaces are ground and etched, or just etched, to remove the oxide film and a P+ zone 9 is formed by alloying a material such as aluminium containing 2% of boron to the wafer. Gold electrode 7 and aluminium electrode 8 are then evaporated on. These electrodes may be made of other metals such as lead and nickel and may be formed by any known method. Ohmic contact to the second layer is made by an electrode 10 consisting of any suitable material. Fig. 3 shows the characteristic curve of the device which may be made to turn on at different applied voltages by varying the potential applied between electrodes 8 and 10. In a second embodiment, Fig. 4 (not shown), the control electrode 10 is placed at a point on layer 5 opposite the tunnel junction so that current between electrodes 8 and 10 flows through layer 5 parallel to junction J E1  and varies the bias across it along its length. In a third embodiment the alloyed region 9 of the device shown in Fig. 1 is replaced by an alloyed N+ region with an ohmic contact which replaces electrode 10 and acts as the control electrode of the device.

Title: Manufacture of 3:4:5:6-halogen-2-amino-1-oxybenzenes
Inventor: RAECK DR MAX
IPC: C07D263/58
Filed: 1935-08-07
Abstract: The process described in the parent Specification in which 3 : 4 : 6-trichloro-2-amino-1-oxybenzene is converted into a 3 : 4 : 5 : 6-tetrahalogen-2-amino-1-oxybenzene by treatment first with phosgene whereby the corresponding oxazolone is formed, followed by halogenation and saponification of the oxazolone ring is extended to the production of 3 : 4 : 5 : 6-tetrahalogen-2-amino-1-oxybenzenes from any 2-amino-1-oxybenzenes which are substituted by chlorine or bromine at least in the 6-position.  In examples: (1) 6-chloro-2-amino-1-oxybenzene is converted into 3 : 4 : 5 : 6-tetrachloro-2-amino-1-oxybenzene; (2) 4 : 6 - dichloro - 2 - amino - 1 - oxybenzene is converted into 3 : 4 : 5 : 6-tetrachloro-2 - amino - 1 - oxybenzene; (3) 4 : 6 - dichloro - 2 - amino - 1 - oxybenzene is converted into 4 : 6-dichloro - 3 : 5 - dibromo - 2 - amino - 1 - oxybenzene.  The 4 : 6-dibromo-compound on bromination is converted into the corresponding tetrabromo derivative, but on chlorination a transfer of chlorine and bromine takes place to yield a mixture of substances which cannot be easily separated; (4) bromination of the 3 : 4 : 6-tribromo compound likewise yields a pure tetrabromo derivative, but on chlorination interchange of the halogen atoms occurs with the formation of a mixed product.

Title: Improvements in a process for blow molding thermoplastic hollow articles and in a device for heating the thermoplastic material
Inventor: LOEW THEODORE
IPC: B29C51/42
Filed: 1954-08-03
Abstract: Before a sheet of, e.g. cellulose or vinyl acetate, or polyethylene, is blow-moulded it is held in contact with the surface of a heated plate which surface has heat retarding means arranged in a pattern such that some parts of the sheet are heated more than others. Insofar as the shape of the mould is non-spherical some parts of the sheet, when expanded, tend to stretch more than others, but if the parts which will be more stretched during moulding are preheated to lower temperatures, and those less stretched to higher, a more uniform final thickness results and thinner sheet material can be used.  One way of arranging the heat retarding pattern is to stick patches of heating insulating material, e.g. of paper, of appropriate shape, on the surface of the plate.  Another way is to cut recesses in the surface of appropriately varying depth and fill them with suitable cement, e.g. a mixture of ground mica and epoxy resin.  A third way is to cut thin grooves in the surface of a depth inversely proportional to the desired rate of heat transfer from the plate. The required pattern of the heat retarding means is obtained by making a sample moulding, with the plate uniformly heated.  If the plastic material is one with an elastic memory the thin parts are marked and the material is shrunk back, by heating, to its original form when it forms a template which can be followed in forming the heat retarding pattern.  If the material does not have an elastic memory a grid pattern is marked on the sample sheet before moulding, enabling each portion of the moulded article to be properly related to its original location on the flat blank and a suitable heat retarding pattern to be designed.
