Title: Encapsulating semiconductor elements in resin
Inventor: HARA AKITOSHI
IPC: B29C45/14
Filed: 1990-09-14
Abstract: A method of encapsulating a semiconductor element (8) in resin comprises mounting the semiconductor element (8) in a mould cavity (12) so that an active side (8a) and a rear side (8b) of the semiconductor element (8) respectively face different parts (12a, 12b) of the mould cavity. Each of the parts (12a, 12b) has a respective resin inflow opening (10a, 10b) for receiving thermosetting resin from a source or sources (11a, 11 b). The mould is heated and separate flows of resin enter the mould through the inflow openings (10a, 10b) so that both the active side (8a) and the rear side (8b) are subjected to the pressure of a respective flow of resin. The setting of the resin encapsulates the semiconductor element. <IMAGE>

Title: Discharge tube and method of manufacture
Inventor: SHISIDO MASATAKA
IPC: H01T14/00
Filed: 1991-09-12
Abstract: The discharge tube eg. for voltage control or gap switching consists of an electrically insulating cylindrical body (1) and a pair of opposed electrodes (2,3) sealed in the cylindrical body with an inert gas inside wherein an activation layer (5) of a silicate compound of alkaline metal is formed over at least pans of the inner wall surface and the electrode surface, other than the discharge surface, that are exposed to the sealed gas. The activation material is a glassy material such as a silicate, aluminosilicate or borosilicate of Li, Na or K with possibly also alkaline earth metal Ba, Sr or Ca oxides. This activation layer helps keep the discharge inception voltage stable even when the discharge frequency changes greatly, which in turn extends the longevity of the discharge tube. In the manufacture of the tube the sintering of the activation layer 5 and the bonding together of the cylinder 1 and electrodes 2, 3 are carried out simultaneously by the same heat treatment. <IMAGE>

Title: Locating a device underground
Inventor: FLOWERDEW PETER MICHAEL
IPC: G01V3/08
Filed: 1992-08-11
Abstract: The position within a horizontal (x,y) plane of a device under the ground, is ascertained by providing the device with an elongate housing including means for generating an electromagnetic field 2, mounted in the housing for rotation relative to the longitudinal axis of the housing in such a way that the field generated is a solenoidal field the axis of which remains substantially vertical when the longitudinal axis is horizontal even when the housing rotates about the longitudinal axis. Dectecting means including at least one aerial for detecting the electromagnetic field generated by the generating means 2, is placed above the ground in the vicinity of the position directly above the generating means, and the signal detected by the aerial is monitored to ascertain the position in the horizontal (x,y) plane of the generating means 2 relative to the detecting means. The shape of the vertical solenoidal field gives a large variation in the field from a position directly above the generator to a position slightly displaced therefrom.

Title: Reducing drag by boundary layer control
Inventor: ROLSTON STEPHEN CARSON
IPC: F02C7/045
Filed: 1995-11-30
Abstract: Boundary layer separation at the surface of a structure such as an intake duct (18) (Fig. 1) of a turbofan aeroengine nacelle (12) at conditions of high incidence and high engine mass flow arises from shockwave induced pressure gradients in the boundary layer. To control separation, gaseous fluid is withdrawn from a high pressure region of the boundary layer downstream of a shock wave 27, conveyed within the intake duct structure and discharged upstream of the shockwave into a low pressure region of the boundary layer. The intake duct (18) embodies a noise attenuation panel 19, and fluid is withdrawn from the high pressure region of the boundary layer into a modified panel section 191 by passage through apertures 30 at a downstream region of the panel section, conveyed along a fluid communication path within the panel section 191 and discharged into the low pressure region of the boundary layer by passage through apertures 30 at an upstream region of the panel section 191. Gaseous fluid is conveyed solely as a consequence of the difference in pressures in the boundary layer at the downstream and upstream regions. The panel section 191 may comprise a cellular structure 151, sandwiched between a porous facing sheet 122 and a backing sheet 11, the cells communicating by means of slots 31. <IMAGE>
