Abstract: An IC is divided into four circuit blocks. These four circuit blocks have the same function. While one of the circuit blocks is not functioning, a mode setting circuit generates mode control signals for selecting a mode in which the operation frequency of the circuit block is set lower than in a normal operation mode. A main control circuit controls the entire operation of the IC, and generates clock signals for defining the operations of the circuit blocks. Sub-control circuits are arranged so as to correspond to the circuit blocks and receive their respective mode control signals and clock signals. Upon receiving the mode control signals, the sub-control circuits controls their corresponding circuit blocks as to whether the circuit blocks are operated in the normal operation mode or at a frequency lower than that in the normal operation mode.

Abstract: A worker platform assembly is modular in construction so as to be configurable according to the configuration and size, particularly width, requirements of each bridge and to metal surfaces thereof which are to be reconditioned by abrasive stripping and recoating. The assembled platform is suspendable at each end by suspension frame assemblies which are rollable along the parapets of the bridge for repositioning the platform assembly, with the suspension assembly being adjustable to various configurations of parapets. An adjustable curtain frame enables sealed enclosure of bridge surfaces to be treated and optimum access of workers to those surfaces during the treatment. Airborne residue is evacuated by vacuum for subsequent disposal in a manner which does not contaminate the environment, while heavier residue and spent abrasive grit is collected and positively moved off of the platform assembly for subsequent, environmentally safe separation and reconstitution of the grit for reuse.

Abstract: A stackable and nestable container is provided which comprises a bottom surface and two pairs of opposed side walls integrally joined with the bottom surface and each other to form a substantially rectangular open-top container. The uppermost surfaces of the side walls collectively form an upper container rim. A container lid is adapted to be received along the upper container rim. Ventilation apertures are formed in each of the side walls. Also, each side wall includes a pair of column sections. Each column section includes a recessed portion, an inner shelf, and a lower column support. The column sections form outer surfaces which project outwardly away from the side walls. By using the column section design, all the support geometry for the container is located in the corners of the container. The upper container rim comprises a double thickness of material around substantially its entire periphery.

Abstract: A dual mode cellular radio communication apparatus includes an echo canceller which cancels echo signals caused by acoustic coupling between a hands-free microphone and a loudspeaker in both analog mode and digital modes. An analog-to-digital converter and digital-to-analog converter may be used both in an analog mode and in a digital mode. A second analog-to-digital converter and a second digital-to-analog converter may be selectively used in the analog or digital mode. The echo canceller may be rendered inoperative during hand-set operation. In addition, a bypass circuit may be provided between an input and an output of the echo canceller so that the echo canceller is bypassed.

Abstract: The improved method of treating activated carbon having an organochlorine compound adsorbed thereon which comprises adding water to said activated carbon and then exposing said activated carbon to ionizing radiation, thereby decomposing and rendering harmless the organochlorine compound adsorbed on the activated carbon is described. The method is capable of safe and efficient decomposition of the activated carbon that has been used in adsorption treatment of organochlorine compounds such as PCBs and trichloroethylene that have heretofore been difficult to treat. The activated carbon that has hitherto simply been accumulated to date after adsorbing organochlorine compounds can be effectively treated by the method at low cost.

Abstract: In ink jet printers in which the printing head (33) is connected to an ink reservoir (16), such as may be used in teleprinter or facsimile apparatuses, it is necessary to foresee the expiry of the ink in the reservoir in order to be able in due time to replace the printing head or the pertinent cartridge. A logic circuit (40) is used to count the number of drops gradually expelled, and, with any necessary correction, compares this number with the maximum number of drops equivalent to a known volume of ink contained on average in the reservoir. Expiry of the ink is indicated in in dependence on the result of the comparison.

Abstract: An integrated, multisensory recognition (identification and verification) system is described. Acoustic features and visual features are integrated in order to identify people or to verify their identities. The integration of the speaker-identification and visual-features-identification functions improves both performance and reliability in the applications envisaged. Various architectures are described for the implementation both of the integration function and of the speaker-recognition and visual-features-recognition functions.

Abstract: A telecommunication exchange system in which the fixed location subscribers, like the mobile station subscribers, are provided with individual identifications which are used to assign communication channel pairs to each call to and from both fixed and mobile subscribers. This is accomplished by use of broad-band cables connected from the exchanges all the way to the fixed subscribers' premises.

Abstract: Upon receipt of the sine (sin .omega.) or the cosine (cos .omega.) of a digital angular frequency, a multiplier performs predetermined arithmetic operations of multiplication on it. An output of the multiplier is stored in a register. An adder-subtracter performs arithmetic addition or subtraction of the output of the register and an output of the multiplier. The arithmetic results are stored in first and second registers or third and fourth registers. The arithmetic operations performed by the multiplier include arithmetic multiplication of outputs (initial values) of the third and fourth registers by the sine or cosine of the digital angular frequency and arithmetic multiplication of the results of arithmetic operations by the adder-subtracter stored in the first and second registers or the third and fourth registers by the sine or cosine of the digital angular frequency.

Abstract: A human gene has been discovered which is genetically altered in human tumor cells. The genetic alteration is gene amplification and leads to a corresponding increase in gene products. Detecting that the gene, designated hMDM2, has become amplified or detecting increased expression of gene products is diagnostic of tumorigenesis. Human MDM2 protein binds to human p53 and appears to allow the cell to escape from p53-regulated growth.
