Abstract: An apparatus for detecting a velocity of an object, includes a light source (1) for generating light having a wavelength λ, a light-transmission block (11) for receiving the light from the light source, and guiding the light onto the object, and a photosensor (9) for detecting the light from the object (7) on which the light from the light-transmission block is incident. The light-transmission block is integrally constituted by a diffraction grating (10) for diffracting the light from the light source to produce two diffraction lights (5a,5b), and an optical element for causing the two diffraction lights from the diffraction grating to be incident onto the object at a predetermined incident angle. The diffraction grating and the optical element are arranged so as to have substantially constant sinϑ/λ independently of a change in wavelength λ of the light from the light source where ϑ is the incident angle of each diffraction light onto the object. A velocity of the object is detected through detection by the photosensor.

Abstract: Disclosed is an improved electrical connector terminal mount which has an engagement piece (16) integrally formed in the terminal base. The engagement piece functions to fix the terminal (7) in an associated terminal slot (4). The engagement piece (16) is a metal strip cut away from the base of the terminal in the form of flattened "V"-shaped cantilever arm. The metal strip consists of a first section (17) bent outward on one side of the base of the terminal and a second section (18) integrally connected to and extending inward from the end of the first section (17) toward the other side of the base of the terminal ending in a free end. An engagement slot (19) perpendicular to the terminal slot (4) is formed within which the engagement piece fits, thereby enabling the terminal to fixedly lie along the center line of the terminal slot and to prevent the vertical movement of the terminal out of the terminal slot.

Abstract: A decoder for a ROM matrix organized in selectable NAND parcels of cells utilizes four selection means driven through five buses for implementing a two-level decoding, thus driving a fractionary number of rows through a plurality of selectable drivers. The architecture of the row decoder, based on a subdivision into a plurality of row drivers renders the circuitry physically compatible with the geometrical constraints imposed by a particularly small pitch of the cells. Subdivision of row drivers has positive effects also on access time, reliability and overall performance of the memory as compared to a memory provided with a decoder of the prior art driving in parallel all the homonymous rows of all the selectable NAND parcels of cells.

Abstract: Supplied with an input signal into which a carrier signal is modulated at a frame period by a data signal and unique words periodically interspersed throughout the data signal, a demodulating circuit (14) demodulates the input signal into a demodulated signal. A frame synchronizing circuit (23) produces an aperture signal which defines an aperture interval determined by the frame period when the demodulated signal has a level which is lower than a predetermined threshold level. Responsive to the aperture signal, a cross-correlating circuit (24) calculates a cross-correlation coefficient between the demodulated signal and a locally known unique word. By the use of the cross-correlation coefficient, a phase error calculating circuit (25) calculates a phase error between a reproduced carrier signal reproduced from the demodulated signal and a regenerated carrier signal which is a correct regeneration of the carrier signal. By the use of the cross-correlation coefficient and the demodulated signal, a frequency error calculating section (31-35) calculates a frequency error between the reproduced carrier signal and the regenerated carrier signal. A carrier regenerating circuit (15) makes the reproduced carrier signal become the regenerated carrier signal in accordance with the phase error and the frequency error.

The speed values continuously recorded in the ring memories during a normal trip are permanently stored in one memory branch (15) when the criterion v = 0 km/h occurs and in the other memory branch (16) when the criterion a > delay threshold X occurs. Subsequent speed values are recorded in the linear memory of the relevant memory area up to the specified time limit after which a change to a free memory area of the respective memory branch (15 and respectively 16) occurs. <IMAGE>

Abstract: A tightly-coupled processor complex comprises two or more processors, the complex being asymmetric in that a feature available on one processor is not available on at least one other processor. A work selection mechanism selects one of a set of one or more ready work units, each capable of execution on one or more of the asymmetric processors. A processor set identification function identifies an "indirect idle" set of processors which can participate as hosts in work reassignment to make use of a previously idle processor, and identifies an "indirect bump" set of processors which can participate as hosts in work reassignment to displace a lowest priority work unit previously executing - any work reassignment being initiated by an assigner means and comprising an optimized number of work reassignment steps reassigning work among one of the processor sets to accomplish a related assignment goal (making use of a previously idle processor, or displacing a lowest priority work unit).

Abstract: A method for the identification of agents that inhibit melanin biosynthesis involves the incubation of test samples in cultures of a fungus that produces melanin. Observation of altered pigmentation in the culture or culture area containing test sample indicates inhibition of melanin biosynthesis. Preferred cultures for the screen contain a fungus that pigments in the light or the dark such as  Cladosporium cucumerinum . Preferred embodiments employ test samples on disks or in wells in solidified cultures and a known melanin synthesis inhibitor as a positive control which is compared to the test sample by simple visual inspection.
