Patent EP-0322718-A2 (EP)
Inventor: MIZUTA HIROSHI
IPC: H01L29/201

Abstract: A resonant tunneling device comprises a superlattice layer (11) which includes an interlaminated structure of three semiconductor layers (5, 6, 7; 26, 24, 22) each having a narrow energy bandgap and serving as a quantum well layer and four semiconductor layers (1, 2, 3, 4; 27, 25, 23, 21) each having a wide energy bandgap and serving as a barrier layer and in which three quantum levels are formed in the quantum well layers. A resonant tunneling phenomenon produced between the quantum levels provide peak current values which are substantially equal to each other, peak voltages which can be set independently from each other, and peak-to-valley (P/V) ratios which are high, thereby realizing the resonant tunneling device which has an excellent performance as a three state logic element for a logic circuit. By increasing the number of quantum well layers and the number of barrier layers, a four or more state logic element for a logic circuit can be realized.

Abstract: The distributed auditing subsystem invention runs in a UNIX-like operating system environment with a hierarchical file system. The invention provides an audit trail of accesses to the objects it protects and maintains and protects that audit trail from modification or unauthorized access or destruction. The audit data generated by the invention is protected so that read access to it is limited to those who are authorized for audit data. The invention enables the recording of events which are relevant to the maintenance of the security of the system, such as the use of identification and authentication mechanisms, the introduction of objects into a user's address space, the deletion of such objects, actions taken by computer operators and system administrators and/or system security officers, and other security relevant events. The invention generates an audit record for each recorded event which includes the date and time of the event, the user, the type of event, and the success or failure of the event. The invention performs an on-line compression of the audit trail log file using a UNIX-type daemon process. The audit daemon process has a restartable feature that enables it to recover after node failures. The invention finds particular application in a distributed processing system in which files may be variously stored at diverse storage locations in the network. In such a distributed system, the audit process of the invention can be carried out on a network-wide, distributed basis so that audit files located at diverse storage locations can be concentrated into a single audit trail log file. 
     In this manner, a secure computer system which conforms to the DoD Standard is achieved, which can generate, manipulate and data compress audit information concerning actions affecting the security of the system.

Abstract: Methods and compositions for increasing stability of enzymes in oxidant dry bleach are disclosed. Enzyme stability is adversely affected by increased temperature, humidity, and the presence of strong oxidants, such as peracids. The invention provides enzyme stability in the presence of oxidant bleaches by coating or encapsulating the enzyme, while providing enzyme solubility suitable for use in bleach mixtures upon introduction to an aqeuous medium. Particularly, alkali and neutral materials act as protection agents, which neutralize oxidant species before they contact and denature the enzyme. Other standard bleaching composition adjuncts such as builders, fillers, buffers, brighteners, fragrances may be included in the enzyme-containing oxidant bleach composition in addition to the discrete coated enzyme granules.

Abstract: This invention relates to a method of reducing the particle size of solid particles and is applicable to the production of very fine particles of a wide variety of solids, includuing relatively hard solids. 
     The method comprises milling a liquid suspension of solid particles in an agitated media mill (13), pumping the milled suspension through a particle size classification device (16) to separate the slurry into a coarse fraction (17) and a fine fraction (18), the particles of the coarse fraction having a greater median particle size than the particles of the fine fraction, recycling the coarse fraction (17) from the particle size classification device to the input of the mill (13), and recycling the fine fraction (18) by pumping (15) it to the classification device, wherein recycling of both coarse and fine fractions are continued until solid particles of the desired reduced particle size are produced. 
     Preferably a single classification device and a single mill can be used, and particles having a median particle size of 0.3 microns or less and a relatively narrow particle size distribution can be produced, even using a hydrocyclone as the classification device.

Abstract: The present invention relates to a method and apparatus for discharging a disc filter. The method and apparatus are excellent for handling fiber suspensions in the pulp and paper industry. In earlier known means, the filter cake thickened on the filter surfaces of the disc filter is detached by means of water or compressed air jets and the cake allowed to freely fall to a axial chute disposed below the shaft level of the filter, wherefrom the pulp most usually is transferred by means of a screw conveyor. The pulp, however, easily clogs the inlet opening of the chute, whereby pulp material accu­mulates in the space between the discs with harmful con­sequences. The above-mentioned problem is solved by arranging a conveying means (9), preferably a belt conveyor, between and/or adjacent the filter discs (6), onto which conveying means the cakes are allowed to fall freely and wherefrom the belt (9) quickly and in a forced or positive manner transfers the cakes further to a discharge chute (4) disposed on the side of the filter, thus preventing the pulp material from accumulating between the discs.

Abstract: A method and apparatus is provided to translate the contents of access registers into information for use in performing addressing functions for multiple virtual address spaces. The access registers represent the full addressing capability of the system but do not directly contain the addressing information. The system has a plurality of general purpose registers (20), a plurality of access registers (22) associated with the general registers, an access list (24,25) having access list entries which is addressed by the contents of the access register, memory storage (30) for holding address space number second table entries (ASTE) (98), where the contents of the access list entry locate the ASTE and where the ASTE contains the addressing information needed to locate a virtual address when combined with the contents of a general register. Access register translation (ART) consists of the process of determining addressing information by using the access list entry and the ASTE. The system has available to it at any one time a selection of one of two domains each represented by an access list. One domain is related to the dispatchable unit task to be performed and the other is related to the address space in which a particular program operates. The ART process selects the domain which the access register is using.
