Abstract: 1,010,689. Semi-conductor devices. HITACHI SEISAKUSHO KABUSHIKI KAISHA. Sept. 4, 1964, No. 36372/64. Drawings to Specification. Heading H1K. In a process for alloying a metal comprising a Group III element with a semi-conductor substrate of a Group IV element, the alloying temperature and rate of cooling are selected so that the Group III element enters in an interstitial form into the substrate and forms a recrystallized layer of N-type conductivity (instead of the P-type produced by the normal substitution process). The Group III impurity preferably has a tetrahedral radius greater than that of the Group IV semi-conductor, and the alloying temperature is kept as low as possible. In the examples given, indium is alloyed with P-type silicon to form a PN junction and with N-type germanium or silicon to make an ohmic contact.

Title: Radar systems

Filed: 1974-08-28
Abstract: 1523113 Secondary radar system PLESSEY CO Ltd 12 Aug 1975 [28 Aug 1974] 37504/74 Heading H4D Transponders in a selected part of a region are interrogated by transmitting omnidirectionally pairs of pulses to cause suppression of transponders m all but the selected part, then transmitting omnidirectionally a pair of interrogation pulses to which the unsuppressed transponders in the selected part reply. Fig. 1 shows a system for use with transponders of the type which are suppressed for at least 25 ÁS if they receive a pulse pair P1, P2 with 2 ÁS spacing, and which reply with pulse-coded data if they receive a pulse pair P1, P3 with 8 ÁS spacing. An airfield 1 has omnidirectional aerials A1-A4 on its perimeter. Aerials A 1 and A2 are synchronized to transmit pulse pairs P1, P3 with a pulse spacing which is altered to establish hyperbolic isochrones 4 sequentially. Thus, all transponders on a given isochrone would be expected to reply to a given interrogation pulse pair P1, P3, with consequent garbling of their replies (which would overlap in time). To overcome this, aerial A2 is used with one of the other aerials to transmit suppression pulse pairs P1, P2 with spacings such that all except one of the transponders on the given isochrone are suppressed. One transponder at a time can thus be interrogated. Its position is determined from its reply code timing or by trilateration using aerials A1, A2, A3 for receiving the reply. In the Fig. 2 system, omnidirectional aerials S1, S2 transmit suppression pulse pairs with pulse spacings such that the first pair causes suppression of all transponders in an isochrone band H1, whereas subsequent pairs suppress all the remaining transponders on the airfield. When the band H1 transponders become unsuppressed (i.e. after a nominal 35 ÁS period) but before the remainder become unsuppressed, a pair of interrogation pulses is transmitted by aerials I1, I2 to be received with 8 ÁS spacing by all transponders in a band H2. Since only those transponders within band H1 are not suppressed at this time, only a transponder disposed within the overlap region of bands H1 and H2 will be interrogated. By varying the pulse spacing, bands H1 and H2 can be scanned stepwise across the whole airfield. To prevent transponders which receive the two pulses of a suppression pair in the reverse of the intended order from being suppressed (which would give rise to a spurious "image" of band H1), the amplitude of the second pulse of the pair is made larger than that of the first and the transponders are arranged to respond only to the correct amplitude sequence. As with the Fig. 1 system, the transponder position is determined by trilateration, the times of receipt of the transponder replies by the aerials being transmitted to a central location by RF or co-ax cable links. Additional pairs of aerials may be used on the perimeter of an airfield having central obstructions, to ensure its complete coverage (Figs. 4 and 5, not shown). The transmitted pulses may be synchronized with the dead time of any local secondary radar system.
