Patent GB-2318631-A (GB)
Title: Warheads
Inventor: WILLCOCKS MICHAEL JOHN WINTON
IPC: F42C19/095
Filed: 1981-10-19
Abstract: An explosive charge (4), Fig.1, for a warhead (2) is shaped as an annulus having a bore (5) which permits throughflow of air and also acts as a symmetrical wave shaping cavity within the charge. Simultaneous detonation of initiators (8) disposed axially along the length of the outer wall (6) of the annulus gives rise to an enhanced blast effect in a radially outwards direction from the other side of the wave shaping cavity. The warhead is particularly suitable for sea-skimming or cruise missiles having predictable radial orientation in flight and requiring air-breathing sustainer motors. The geometry of the charge permits maximum damage to be inflicted in a selected direction, eg downwards, allowing the warhead to be used in an over-flying as well as a penetrating role. Embodiments including additional surface concavities 12, Fig.3, and subsidiary charges (22, Fig.5) to enhance the radial effect are also described.

Title: Semiconductor processing involving ion implantation
Inventor: VOSHCHENKOV ALEXANDER MICHAEL
IPC: H01L21/203
Filed: 1982-06-18
Abstract: A molecular beam epitaxial method of fabricating a semiconductor device is disclosed wherein the dopant is implanted by establishing a plasma containing ions of the dopant and the ions are coupled through a drift chamber to impinge on the growing substrate surface. The plasma formed in the ion gun has ions of boron and arsenic and therefore the dopants selected for implantation can be determined by setting a mass filter present in the ion gun. A change to the dopant of the opposite conductivity type can be accomplished in seconds by simply readjusting the mass filter in the ion gun.
