Title: Elimination of residual spacecraft nutation due to propulsive torques
IPC: B64G1/38
Filed: 1975-09-11
Abstract: 1514745 Control systems for spacecraft R C A CORPORATION 11 Sept 1975 37403/75 Headings G3N and G3R In a spacecraft of the dual spin type (i.e. spun inertia wheel and de-spun platform) the undesired nutation which is produced when an off-centre-ofgravity thrust is applied is reduced by applying the thrust for an integral number of times the characteristic nutation period. A mathematical explanation is given. The thrust is applied by a jet thruster (12), Fig.19 (not shown), the magnitude being adjusted so that, when applied for the prescribed time, a desired result (e.g. correction of attitude) is produced. The thrust command signal may be transmitted from a ground station in response to an on board altitude deviation sensor or otherwise, or it may be generated on board from the sensor output. The thrust time is calculated on board by a logic circuit which has stored information of the spacecraft's moments of inertia and angular momentum.

Title: P-n junction formation
IPC: H01L29/167
Filed: 1958-11-20
Abstract: 894,984. Semi-conductor devices. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Nov. 20, 1958 [Nov. 20, 1957], No. 37422/58. Drawings to Specification. Class 37. A method of forming a PN junction comprises cooling a molten semi-conductor material containing a donor and an acceptor impurity at successively different rates, so that the donor or acceptor impurity respectively is dominant in adjacent layers of the recrystallizing material. The relative concentration of the donor and acceptor in the melt is such that at a predetermined rate of cooling the concentrations in the recrystallizing material are substantially identical. Since the variation of segregation coefficient with rate of cooling differs for the donor and acceptor a cooling rate above the predetermined rate gives rise to a predominance of one impurity in the recrystallized material and hence to material of one conductivity type, and a cooling rate below the predetermined rate results in the production of material of the opposite conductivity type. In one embodiment a mass of indium-antimony alloy is melted on the surface of a P-type germanium body to dissolve some of the germanium. The assembly is then rapidly cooled so that the initially recrystallizing material contains a predominance of antimony and is N-type. Subsequently the rate of cooling is reduced to a value at which indium predominates in the recrystallizing material which is therefore P-type. The thickness of the N-type zone is determined by the duration of the rapid cooling step, and the sharpness of its junction with the overlying P-type material by the rate at which the rate of cooling is reduced. An intrinsic region of controlled thickness may be formed between the P and N regions by holding the rate of cooling at the value corresponding to an indiumantimony balance for a fixed interval between the rapid and slow cooling steps. Multiple junctions are formed by repeated changes in the rate of cooling.
