Abstract: Blocks molded of coal ash to be effectively utilized for civil engineering and construction works. To produce the blocks of the foregoing type, a large quantity of coal ash recovered from coal combustion installations, e.g., power station and others is used. Each block has various properties such as water permeability, water impermeability, sound shielding (sound absorption or sound arresting) or the like depending on the field of application where the blocks are practically used. The blocks are produced by way of steps of mixing coal ash of 40 to 80 % by weight with a composite material of 20 to 40 % by weight comprising scherben, feldspar, bentonite and dolomite, molding the resultant mixture to a predetermined configuration corresponding to the blocks to be produced and then allowing the resultant molded product to be subjected to burning. The final products of blocks have excellent properties substantially equivalent to those of blocks molded of cement and tiles molded of a high quality of clay. Particularly, to assure that the blocks have specific properties of water impermeability and sound shielding, coal ash is preformed in the shape of a large number of grains to be used as raw material. After completion of the molding operation, the molded product is coated with a glazing material.

Abstract: A Josephson junction device is disclosed having a substrate upon which are located overlying and underlying high temperature crystalline oxide superconductive layers separated by an interposed impedance controlling layer. The underlying superconductive layer is limited to a selected area of the substrate while the overlying and interposed layers overlie only a portion of the underlying superconductive layer. Nonsuperconducting oxide layer portions laterally abut the superconductive and interposed layers. A first electrical conductor is attached to the underlying superconductive layer at a location free of overlying oxide layers, and a second electrical conductor contacts the overlying superconductive layer and extends laterally over the adjacent laterally abutting nonsuperconductive layer portion.

Abstract: A video input signal (IN) is applied to a delay circuit (22) having a plurality of taps (a;b;c;d;e) which are coupled to maximum (40) and minimum (50) value selection circuits. In the absence of a video signal transient, the center tap (C) of the delay circuit is coupled to an output terminal (OUT) via an output switch (60). When a "white going" transient occurs, the output switch sequentially selects the outputs of the minimum and maximum value selectors for application to the output terminal. When a "black going" transient occurs, the output switch sequentially selects the outputs of the maximum and minimum value selectors for application to the output terminal. Offset producing circuits (42;52) are coupled to the minimum and maximum value selectors whereby an output signal is produced having a preshoot, an overshoot and a rapid transition therebetween for video input signal transients of either direction and in which the shoot amplitudes are independently controllable thereby providing the combined transition speed advantages of "edge replacement" enhancement systems with pre-shoots and over-shoots characteristic of transversal peaking systems.

Abstract: In each module (11) of three or more central processor modules of a fault tolerant computer system, a detector (45) receives a comparator output signal and like comparator output signals from two adjacent modules and produces a detector output signal which confirms absence and presence of a fault in one of the above-mentioned each module. When the fault is confirmed, a controller or processor (49) isolates the module under consideration from the system by inhibiting delivery of a controlled output signal to a bus (31) and by connecting, with the module in question bypassed, switching units (53(1), 53(2)) of the adjacent modules. Preferably, one of the modules of the system is used as a master module of ordinarily delivering the controlled output signal to the bus with others used as checker modules of ordinarily inhibiting the delivery. When a fault appears in the master module, its controller delivers a module operation switching signal to the controllers of the checker modules to thereby substitute one of the checker modules for the master module subjected to the fault.

Abstract: A magnetic head assembly, for use in a tape drive wherein a tape is moved past the head assembly in a longitudinal direction and the tape exhibits transverse tape movement correlated with the position of the tape in the longitudinal direction, and wherein a minimum longitudinal distance exists for which the correlation is maintained, has a carrier with first and second gap and coil arrangements disposed on the carrier. The respective gaps in the first and second gap and coil arrangements are disposed on the carrier separated by a spacing which is less than the aforementioned minimum longitudinal distance. If one gap and coil arrangement is used as a write arrangement, and the other gap and coil arrangement is used as a read arrangement for verifying the writing of data by the write arrangement, tracking errors are minimized, or substantially avoided, because the write and read arrangements are so close to each other as to be effectively at the same position in the context of the transverse tape movements.

Abstract: In certain signal transmission systems such as selective call systems it is desired to stamp the date and time of the receipt of a call addressed to a receiver. For battery powered equipments such as radiopagers it is not practical to provide a clock because it will require resetting after each battery change. Fairly accurate times can be obtained by the system base station transmitting date and time message signals at regular intervals. However due to signal formatting delays and signal propagation delays, both of which are variable, the time indicated in a received time message signal is incorrect relative to real time. A radiopager includes a timing stage which is able to measure real time relative to a time reference. In order to obtain the best time reference, a comparison is made between the real time difference (Tr n  - Tr ref ) between the times of receipt Tr ref , Tr n  of a current time reference signal and a more recently received time message signal Ts ref , Ts n , and the time difference (Ts n  - Ts ref ) between the times Ts ref , Ts n  indicated in the corresponding time message signals, and depending on the result either the time reference signal Ts ref  is confirmed as the current time reference signal or the more recently received time message signal is substituted as a new current time reference signal causing the real time clock to be reset so as to relate the real time to the new current time reference signal.
