Abstract: Methods and apparatus are disclosed for realizing an integrated cache unit which may be used to flexibly implement a plurality of multiprocessor support schemes. The preferred embodiment of the invention comprises both a cache memory and a cache controller on a single chip and is programmable. The flexible implementation of the support schemes is achieved, according to the preferred embodiment of the invention, by providing for the setting of internal ICU option bits in on-chip special registers. The setting of these bits translates into the selection of a desired support scheme. The bits may be set under software control and allows a high performance multi­processor cache system to be designed with few parts, at low cost and with the ability to perform with high efficiency.

Abstract: A method and apparatus for manufacturing a preform for a fluoride glass fiber. 
     Cooling means (13) and a liquid reservoir (14) are provided in association with a cylindrical vessel (1) open at both ends, and a crucible open (3) at both ends is disposed in the cylindrical vessel. Glass for clad and for core (2,4) are loaded into the cylindrical vessel and the crucible, respectively, with their lower open ends plugged, and are made molten. 
     The clad glass melt is then cooled and when the outer portion of the clad glass melt has solidified with its inner portion still molten; the plugged lower open ends of the cylindrical vessel and the crucible are opened to let the inner portion of the clad glass melt run out into the liquid reservoir, and to introduce the core glass melt into the void from which the clad glass melt has run out. The glass is then cooled and solidified in its entirety, thereby forming a core-clad layer structure.

Abstract: An apparatus and a method for adaptively discriminating high and low levels of data signals to be demodulated into digital signals, which includes a reference signal generator, first and second sample and hold circuits, a discrimination signal generator, a timing signal generator and a discriminator. The first sample and hold circuit samples data signals at first discrete times at which the discriminator detects a high level of the data signal in relation to a discrimination level, and outputs a first sample signal whose level depends upon the level of the data signals at the first discrete times. Similarly, the second sample and hold circuit samples a low level of the data signals and outputs a second sample signal whose level depends upon the level of the data signals at the second discrete times. The apparatus further includes a signal generator which generates an average of an absolute value of the levels of the sample signal first and that of the second sample signal and a further signal generator which generates an inversion of the average signal. An additional signal generator has a low-pass filter and selector to selectively apply one of the average and inversion signals to the low-pass filter. The selector applies the inversion signal when the discriminator detects that the high level of the data signals has been inputted, otherwise, it applies the average signal. The output of the low-pass filter is a reference signal formed of a composite of the inversion and average signals. The reference signal is applied to the discrimination signal generator which produces the discrimination level so as to adjust the level of the discrimination level in proportion to the level reference signal.

Abstract: A demodulator mechanism which uses estimates of the in-phase and quadrature-phase components of differential phase modulated carrier signals for performing a coherent demodulation of these signals is described. The instantaneous estimates, obtained from an estimator circuit, are fed into a differential carrier recovery circuit, which provides for a feedback of ideal sine and cosine components, and combined with the instantaneous estimates for incrementally decreasing a phase error signal generated in a computational circuit. By thus incrementally decreasing the phase error signal, an ideal phase angle is eventually obtained, thereby providing for coherent demodulated output components of the input carrier signals.

Abstract: A high frequency oscillation type proximity switch, comprising: an oscillation circuit (13) having a first resonant frequency; a tank circuit connected in a positive feedback path of the oscillation circuit (13) and including an LC resonant circuit having a second resonant frequency slightly different from the first resonant frequency; and a comparator circuit (5) which discriminates the amplitude of an oscillation output of the oscillating circuit (13) at a predetermined threshold level; the comparator circuit (5) producing a detection output signal when a nonmagnetic metallic object is brought to a certain proximity of a coil included in the LC resonant circuit and a level of the oscillation has thereby changed by a certain amount as a result of a change in the susceptance of the coil. Since the approach of a magnetic object increases the loss of the coil whereas the approach of a nonmagnetic metallic object increases the susceptance of the coil, it is possible to detect magnetic objects alone, nonmagnetic metallic objects alone, or both magnetic objects and nonmagnetic metallic objects alike by appropriately selecting the resonant frequencies of the oscillation circuit (13),and the tank circuit and the threshold level of the comparator circuit (5).

Abstract: In a slotted core optical cable in which each slot contains stacked optical fibre ribbons, the cost of the cable can be reduced and cooling of the slotted core during manufacture of the cable is facilitated as compared with an optical cable in which the slots of the slotted core are all of the same depth by forming the circumferentially spaced slots into two groups, the slots of each group being of the same depth as one another and the depth of each of the slots 3 of one group being greater than the depth of each of the slots 4 of the other group, and by arranging for each slot 3 to be disposed between two slots 4. The number of optical fibre ribbons 5 stacked in each of the slots 3 is greater than the number of optical fibre ribbons stacked in each of the slots 4. Approximately the same number of optical fibre ribbons can be accommodated in slots of a core of smaller diameter than hitherto achieved.

Abstract: A secure teleconferencing method for a key management system is shown. This method directly establishes a secure teleconference among a number of terminals without the intervention of a certifying authority. The terminals (A-D) of this system have been previously certified by a common certification authority. Upon detection of a secure teleconference, the terminals orient themselves in a master/slave (1-16,22,23) configuration. The terminals exchange certification messages (24-43,45). As a result, each terminal determines the identity of the other terminals (44,46). Under the supervision of the master terminal, the terminals establish a single session, session key which permits secure communication among the terminals (47-58). A new session key is randomly generated for each teleconference call. A minimum number of messages is exchanged to establish the secure teleconference.
