Inventor: IRIKAWA MICHINORI C O THE FURU
IPC: H01S5/00
Filed: 1991-11-18
Abstract: A semiconductor optical device comprising a mesa shaped double heterostructure having an active layer on an InP substrate, and pn junction current blocking layers embedded at all sides of the said double heterostructure, wherein at least portion of said current blocking layers consists of a semiconductor layer lattice-matched to InP and having a band gap larger than that of the InP at a room temperature. Therefore, the current blocking characteristics of the current blocking layer is improved so that the increase of leakage current under operating condition of high temperature and high output power is well suppressed, and the nonlinearity in the optical output-current characteristic is drastically reduced even under such operating conditions.

Title: Ternary brazing based on a Zirconium/Nickel alloy
Inventor: HEGNER FRANK DR
IPC: C22C16/00
Filed: 1991-10-18
Abstract: This active brazing alloy is preferably used for brazing (joining) (aluminium)oxide ceramic parts or single crystals or metal parts to parts of the same material in each case, or (aluminium) oxide ceramic parts to single crystals or (aluminium) oxide ceramic parts or single crystals to metallic parts. In addition to the zirconium/nickel alloy composed of 70 to 85 atomic % of zirconium and 15 to 30 atomic % of nickel, it contains titanium. In a device for producing a uniformly thick strip (6) of this ternary active brazing alloy which has two surfaces which are as smooth as possible by the melt-spinning method, the alloy which has been melted by means of high-frequency energy in a cylindrical crucible (1) composed completely of a highly heat-resistant and highly thermally conducting, nonmetallic material, in particular of high-density graphite or boron nitride, is squeezed out through an opening (3) in the base of the crucible onto a metal drum (5) which is rotating at high circumferential velocity and has a high thermal conductivity, and the liquid alloy solidifies on the drum at a high cooling rate in the order of magnitude of 10<3> to 10<6> DEG C/s. A product produced using said ternary active brazing alloy is a pressure sensor (10) comprising a parent body (12) and a membrane (11) made of ceramic, in particular aluminium oxide ceramic, preferably having a purity of 96% by weight, the parent body (12) and the membrane (11) being thermally joined parallel to one another at their edges and at a known distance (d) by means of the active brazing alloy, for example by means of a shaped part (20) thereof, to form a chamber (13). <IMAGE>

Filed: 1992-01-09
Abstract: The mounting and final plate can be used for so-called modular fixture systems which have grids determined by mating holes (5). The mounting or final plate (3) forms the "last" part of the fixing system, i.e. it is directly connected to the workpiece and therefore constitutes a "lost" plate which can be adapted to the workpiece by machining. In this way, defined and reproducible fixing of identical workpieces is possible in a quick and simple manner, since this plate is then always available for these workpieces. The projections (6) on the side remote from the workpiece are adapted to the grid system formed by the mating holes (5) so that corresponding reproducible and accurate fastening, even turned through 90 DEG , is possible. The fastening holes for the mounting or final plate run through the projections (6). <IMAGE>

Inventor: HERZBERG AMIR
IPC: G06F21/31
Filed: 1992-03-13
Abstract: Method and apparatus for authenticating users (entities) of a computer network based on the entity's identification is described. Keys for each party of a potential session are derived by projections stored at each party's location. The projections are based on a partially computed function which can be in encryption by some key of the user identification or a multivariable polynomial or other function which is partially evaluated for one user's identification. Each user evaluates his projection with the other user/party's identification. The evaluated quantities are compared using a validation routine. The method requires only one basic piece of information, the projection to be distributed to each user, and does not need specific keys for specific users (or other users' information stored in one user's memory or global network). The method enables adding users to the system directory in a flexible way, without having to notify users of the addition. The method applies to communication heirarchies and inter-domain communication, as well.

IPC: G11C29/00
Filed: 1992-04-11
Abstract: An invention is disclosed which implements bit line redundancy in a memory module, such as a dynamic random access memory (DRAM), in accordance with a block write operation. The block write operation is commonly used in dual port RAMs, sometimes referred to as video random access memories (VRAM). Specifically, a block write operation allows a plurality of bits of data to be written to any combination of a plurality of adjacent bit lines defined by a column address. The precise combination of adjacent bit lines selected by the column address is designated by an address mask. The invention provides a memory module with a redundant bit decoder that incorporates the address masking function into the redundant bit decoder during block write operations and also bypasses the masking function during normal read and write operations. This redundant bit decoder allows a single redundant bit line to replace any single defective bit line of the selected group of block write bit lines. It eliminates the need for replacing all the selected bit lines and, thereby, saves silicon area and maximizes the utilization of the available redundant bit elements.

Abstract: Disclosed are compositions of particulate citric acid or an alkali metal or alkaline earth metal salt thereof prepared by an improved method and an improved method of preparing a detergent builder composition. The method of preparing particulate citric acid or salts thereof involves spray granulating citric acid or a salt thereof from its partially purified fermentation broth to form granules which are freer flowing and less inclined to fracture than is citric acid or its salts prepared by crystallization techniques which properties render the material prepared by the present method suitable for handling in bulk. The same properties may be imparted to detergent builder compositions by adding detergent builders to the partially purified fermentation broth or by introducing a detergent builder solution into a fluidized bed reactor together with appropriate seed particles to thereby form granules which include such detergent builders. This method may be used advantageously to prepare the detergent builder, tartaric monosuccinate/tartaric disuccinate which is particularly difficult to crystallize, in a dry granular form.

Abstract: A smartcard that allows different Service Providers to coexist on the smartcard with none of the Service Providers, nor the owner of the smartcard, having access to the files created for, or by, each of the resident Service Providers. The operating system of the smartcard includes a root directory that is owned by the smartcard's issuer/owner, and each Service Provider is a "user" that is installed by the issuer/owner. Each such user is provided with a subdirectory of the root directory, and within the subdirectory the user creates files and subdirectories with files, as the user deems necessary. The operating system prevents all users of the smartcard, including the smartcard's issuer/owner and the smartcard's holder, from accessing any files that are owned by any other user, when that user chooses to prevent such access. This power to exclude is effected through a password file that is owned by the user and which cannot be altered by any other user, including the smartcard's issuer/owner. Optionally, the smartcard's issuer/owner is given the power to erase all files of a given user. Connection is effected with a protocol which authenticates all parties to the connection. Thus, in a connection between the smartcard and a user, the smartcard determines whether the user should be granted access, and the user determines whether the smartcard is a valid smartcard. Authentication of the possessor of the smartcard may also be effected.
