Patent EP-0327852-A2 (EP)
Inventor: CLARK CARL EDWARD
IPC: G06F12/10
Filed: 1989-01-20
Abstract: The invention includes the creation of address spaces that need not map in their address range all of the routines of the operating system basic control program (BCP). The BCP, though, will have easy access to (addressability of) the home address space, i.e. to the virtually mapped and addressable control blocks therein. Addressability can be switched from a previously dispatched address space to the home address space. The dispatcher becomes capable of addressing the home address space when predetermined bits in a program status word are set. Once the home address space becomes addressable, the BCP is now capable of easily accessing control blocks in the home address space without the need to modify CPU status or pointers to any other address spaces. If pointers to any other address space are modified, current address translation in the home address space would not be affected. Providing access to the home address space increases performance and reduces complexity.

Abstract: In an electrical panel connector, the male part surrounds a blade contact element, while the female part has a socket element, constructed with a bevelled flat profile. In order to improve the making of contacts and hence, nevertheless, to keep the insertion forces low it is proposed to use a complete rectangular profile for the socket element, the narrow and broad sides of which rectangular profile are split by longitudinal slots into a family of parallel webs which form a bevelled cage, with contact webs which are kinked or bent into the interior of the cage. In consequence, in the event of coupling, the kinked or bent tips of a contact web also come into contact on the blade edge of the male part.

Abstract: Disclosed herein is a vacuum switch tube which comprises a highly conductive member provided on a back surface of a main electrode. The highly conductive member prevents an arc formed upon breaking a large current from locally concentrating or stagnating, and promotes rapid and smooth movement of the arc from the main electrode to an auxiliary electrode. Marked enhancement and stabilization of the performance of the vacuum switch tube in breaking a large current, as well as a smaller construction, are thereby realized.

Abstract: A short-period, strained superlattice structure (10) includes two coupled quantum well layers (12,14) separated by a barrier layer (16). The quantum well layers are preferably formed of indium arsenide and are 2 monolayers thick. The barrier layer is preferably formed of gallium arsenide and is 2 to 10 monolayers thick. The quantum well layers have a lattice parameter or constant which is sufficiently different from that of the barrier layer that a permanent strain exists in the structure. The layers are sufficient­ly thin that they remain in an unrelaxed state, thereby precluding the formation of misfit dislocations. As an alternative, the superlattice structure may include more than two quantum well layers, each adjacent two of which are separated by a barrier layer. As another alternative, a plurality of structures, each including two quantum well layers separated by a barrier layer may be provided, with each structure separated by a gallium arsenide buffer layer on the order of 170 to 204 angstroms thick. Where incor­porated into a semiconductor diode laser as an active region, the strained superlattice structure is capable of exhibiting optical bistability.
