Abstract: A cryptographic system allows, in one exemplary use, a supplier (101) to cryptographically transform a plurality of messages responsive to secret keys; the transformed messages to be digitally signed by a signer (102); and the signed transformed messages returned to the supplier (101) to be transformed by the supplier (101), responsive to the same secret keys, in such a way that a digital signature related to each original message is developed by the supplier (101). One important property of these systems is that the signer (102) can not determine which transformed message received for signing corresponds with which digital signature-even though the signer (102) knows that such a correspondence must exist.

Abstract: Two-dimensional images of a three-dimensional body (14) photographed bytwo video cameras (10,12) are parallactically compensated prior performing the detection of the corresponding point necessary to recognize the body. Namely, the parallax between both cameras (10, 12) for the object distance (do) measured by a range finder (22) is calculated by parallax calculator (26), and one image is electrically shifted by an image shifting circuit (32) by only the number of pixels in accordance with the parallax value, thereby performing the parallax compensation of the images. In a calculation processing unit (20), the correlation values for the corresponding points between both images are calculated, and the distance images of the body (14) are produced on the basis of these correlation values.

Abstract: Deep trenches (14, 15) are formed according to the desired pattern through the N epitaxial layer (13) and N +  subcollector region (12) into the P- substrate (11) of a silicon structure (10). Where a substrate contact is needed, the trenches delineate a central stud (16) or mesa of silicon material. Channel stop regions (18) are formed e.g. by ion implantation of boron atoms at the bottom of trenches. Si0 2  and Si 3 N 4  layers (17, 19) are then deposited on the whole structure. A substrate contact mask is applied and patterned to selectively expose one side of the trench sidewalls, the bottom of the trenches adjacent thereto and others areas if desired such as the top surface of the stud. The composite SiO 2 /Si 3 N 4  layer is then etched to leave exposed only the sidewalls of the stud, at least partially the bottom of the trenches adjacent thereto and the top surface of the stud. Platinum is deposited preferably via sputter deposition, conformally coating all regions of the structure. After sintering, the unreacted platinum is removed using wet chemical etch (aqua regia). Platinum silicide is left in all opened contacts and on the stud sidewalls where its defines a metal silicide lining (25) or cap, covering the stud. This lining connects the top surface (25a) of the stud, with the channel stop implanted regions (18) and thence forms the desired substrate contact.

Abstract: A multiprocessor system is comprised of a bus (13) and a plurality of processor modules (11). Each processor module includes a bus arbitration block (21), a bus access control block (23), an address output block (25), a data input/output block (27), a clock signal generating block (29), a stop request block (47) for requesting the stop of supplying a clock signal, a operation processing block (45) for processing data, and a stop control block (33). The stop control block (33) stores the contents of the bus access (a type of the bus, the address and data concerning the access, etc.) as was made by said operation processing block (45) when the clock signal is stopped, and to what clock of that access cycle the bus access proceeds. The stop control block 33 controls the bus arbitration block (21) to electrically disconnect the processor module (11) from the bus (13). After the restart of supplying the clock signal, the bus arbitration block (21), the bus access control block (23), the address output block (25) and the data input/output block (27) are restored on the basis of the contents of the bus access. And then the bus access as was stopped is resumed from its beginning. When the number of clocks of the clock signal is equal to that stored in the memory block after the restart of supplying the clock signal, the stop control block (33) supplies again the clock signal to the operation processing block (45). Subsequently, the operation processing block (45) continues the bus access.

Abstract: Methods and apparatus are described for implementing fork operations on UNIX or UNIX-emulating operating systems, particularly in multi-user environments. The invention reduces the copy time, the number of page faults and, consequently the input-output ("I/O") operations between the central processing ünit, main memory and auxilliary memory. In one aspect of the invention, fork operations are executed by redefining those pages of the parent process image resident in main memory as pages of a child process image and modifying the page maps accordingly. Page faults are thereby eliminated for pages located in auxiliary memory. Additional improvements in performance are obtained by monitoring the level of main memory utilization and selecting optimal procedures based on the amount of excess capacity in main memory.

Abstract: A compound semiconductor laser comprises a semi-insulating substrate (1), a lower clad layer (2), a MQW active layer (31, an upper clad layer (4A), and two electrodes on the top surface thereof. The uper clad layer (4A) is formed so as to have a property of reducing the diffusion coefficient of impurities, from the lower portion towards the upper portion thereof. Impurity atoms are thermally diffused into the lower clad layer (2) from the top surface thereof to form an N-type region (6A) and a P-type region (7A), respectively. The side diffusion fronts of the N- and P-type regions (6A, 7A) are nearly vertical, and thus a narrow MQW active region (13A) is defined by disordered portions (11A, 12A) of the MQW active layer in the N- and P-type regions. The light and carriers are effectively confined in the narrow active region (13A) by using the resulting vertical and transverse double-heterostructures and refractive index differences.
