Abstract: A circuit for quickly determining if all of the data bits in an ECC word are correct and/or for detecting failures in an error detection syndrome generation path in an ECC circuit, where the ECC circuit utilizes an error correction code with two diagonal quadrants in the code matrix composed entirely of columns which have an even number of ones, and with the other two quadrants composed entirely of columns which have an odd number of ones. 
     In one embodiment, the circuit comprises for generating a parity bit, P k , for each of K data fields in the ECC word; for comparing logical combinations of these parity bits to logical combinations of the memory check bits, C j , to form H bits; and for logically combining these H bits to form a D bit. This D bit may be compared to the binary (non carry) sum of the syndrome bits to detect syndrome generation path failures. This D bit may also be used to determine if the data bits in an ECC word are correct, a number of cycles before the completion of the normal ECC operation.

Abstract: A method of storing and transforming heat and of generating cold by means of two metal-hydride and metal-hydrogen systems operating in conjunction in closed circulation at different temperatures. Magnesium hydride, especially active magnesium hydride, is employed as a high-temperature hydride. A hydride with a hydrogen-dissociation pressure that is lower than that of the magnesium hydride subject to the conditions of thermal dissociation and higher than that of the magnesium hydride during its recovery is employed as a low-temperature hydride.

Abstract: Retroreflective construction comprising a monolayer of microspheres (2) with associated dielectric mirrors (10) which are hemispherically surrounded by tangentially-oriented, preferably contour-conforming, reflective pigment nacreous flakes. The dielectric mirrors (10) and reflective nacreous pigment flakes cooperate additively substantially without interfering with each other to provide a high brightness retroreflective sheet. The novel sheets retain much of their reflectivity after several launderings or drycleanings and, in some embodiments, can be made very flexible, making them well-suited for use as reflective fabrics.

Abstract: A tunnelling transistor has an injector layer (32) separated from a channel (28) by a tunnelling barrier (30) of narrow band gap semiconductor material. When biased to threshold with a first voltage, the injector layer injects charge carriers through the tunnelling barrier and into the channel by quantum-mechanical tunnelling. Two spaced-apart contact regions (24,26) disposed on each side of the channel are provided to establish a current which flows between the contact regions through the channel when the channel resistance is lowered by the injection of charge carriers across the tunnelling barrier. By biasing the injector layer with a second voltage, the tunnelling process is reversed, causing charge carriers to tunnel from the channel back through the tunnelling barrier and into the injector layer. The channel current flowing between contact regions is turned off when channel resistance is sufficiently increased. Since tunnelling is inherently a fast process, the transistor has an ultra-fast switching time.

Abstract: A method of forming a textured layer of tin oxide on a vit­reous substrate in which the thickness and degree of texture of the layer can be controlled independently of one another. The method comprises the steps of depositing a first film of tin oxide on the substrate by chemical vapor deposition from a first reactant mixture of tin chloride, water, and an alcohol and depositing a second film of tin oxide on the first tin oxide film by chemical vapor deposition from a second reactant mixture of tin chloride and water. Where the substrate is ordinary soda lime glass, it preferably is first coated with a film of silicon dioxide. The method permits deposition of substantially uniform layers of tin oxide in a continuous deposition process.

Abstract: A speaker driver is operated by a battery and drives a speaker to generate an alert tone in response to an externally input intermittent signal. The speaker driver includes a reference voltage generator for generating a reference voltage, a transconductance amplifier for outputting a current corresponding to a differential voltage between a voltage of the battery and the reference voltage, an output control switch for ON/OFF-controlling the output current from the transconductance amplifier in accordance with the intermittent signal, and a DC amplifier for amplifying the ON/OFF-controlled output current as a driving current for the speaker. Since a speaker driving current is decreased as a power source voltage is dropped, an abnormal voltage-­drop during an alert generation period can be prevented, thereby prolonging the service life of a battery.
