Patent EP-0414477-A2 (EP)
Inventor: AKAOGI TAKAO
IPC: G11C29/04
Filed: 1990-08-21
Abstract: A semiconductor memory device includes a memory cell array (3), a data readout circuit (4, 5), a decoder circuit (1, 2) and an address transition detecting circuit (6) which detects an address transition of an input address signal (A) and which generates an address transition detection pulse (D). A redundancy circuit (7, 8) determines whether or not the input address signal indicates a defective memory cell and outputs a redundancy signal (E) to the decoder so that the decoder selects one redundant memory cell (RMC) in place of the specified defective memory cell (MC). A pulse generator (9) generates a pulse signal (G) having a pulse duration time (t₁ + t₂) sufficient to reset the memory cell array and the data readout circuit before reading data from the memory cell array in a case where the redundancy circuit outputs the redundancy signal. The pulse duration time of the pulse signal starts from a time when the address transition detecting circuit generates the address transition signal.

Abstract: The invention relates to an apparatus by means of which, to change the rolls, the chocks of the upper working roll can be supported on those of the lower working roll in such a way that the rolls rest freely one above the other and their shells do not touch. According to the invention, the chocks of one of the rolls are equipped with swivellable supporting levers which, in their normal position, engage around flanks of the opposite chocks and, during adjustments of the stand, are capable of sliding on the said flanks. To change the rolls, however, the upper working roll is raised together with its chocks in such a way that the spring-loaded supporting levers can swivel inwards and engage in grooves in the opposite chock and, during the lowering of the upper working roll, are supported against the base of these grooves. During the installation of a set of rolls, the upper working roll is likewise lifted and the supporting levers are then spread apart, for example by means of a drive or locking devices, so that, as the upper working roll is lowered, they slide past the groove supporting them and can come to rest against the flanks of the opposite chock.

Abstract: A temperature detecting block for a thermal sensor roll houses a plurality of thermocouples which are located at different depths in the block. One or more such temperature detecting blocks are attached to the surface of the thermal sensor roll. When the thermal sensor roll is held in contact with a metal strip being rolled, temperatures in the thermal sensor roll are measured by the different plurality thermocouples. The temperature of the metal strip in contact with the surface of the thermal sensor roll can then be calculated from the temperature gradient in the thermal sensor roll in a radial direction of the thermal sensor roll, without the influence of external disturbances. The calculated temperature of the metal strip being rolled is then compared with an experimentally determined temperature of heat streak formation, to predict the formation of heat streaks with high accuracy.

Abstract: To permit a user to listen to a broadcasting program of the same network in good receiving conditions when a multipath occurs on an RDS broadcasting wave that is being received at an intermediate field intensity, it is judged whether or not a lock detection signal is produced from a lock detector every unit time during reception of a broadcasting wave; and when the frequency of judgement in a set time that no lock detection signal is produced is greater than a reference value, frequency data of one station of that group of network stations to which a broadcasting station of the receiving broadcasting wave belongs is read out from a memory and the reception frequency is switched to the frequency indicated by the current frequency data read out. To ensure quick transition to the reception of the RDS broadcasting wave that can assure good receiving conditions even when a vehicle is driving in a tunnel or a mountainous area, an average level of a reception signal level of a currently receiving broadcasting wave may be calculated in a predetermined time at every given timing, and when a previous average level is higher than a first predetermined value and a current average level is lower than a second predetermined value smaller than the first predetermined value, or when the previous average level is lower than the second predetermined value and the current average level is higher than the first predetermined value, frequency data of one station of that network station group to which a broadcasting station broadcasting the currently receiving broadcasting wave belongs is read out from the memory, and the reception frequency is switched to the frequency indicated by the read out frequency data. Further, to ensure quick transition to the reception of the RDS broadcasting wave that can assure good receiving conditions even when the reception of the currently receiving RDS broadcasting wave becomes poor, when such poor reception of the currently receiving RDS broadcasting wave occurs, those pieces of frequency data which can assure a field intensity equal to or higher than a set level are first extracted from a frequency data list stored in the memory, then that piece of the extracted frequency data which has the highest reception signal level is selected, and the reception frequency is switched to the frequency indicated by the selected frequency data.

Abstract: It is known to hold the at least three plates of a stack (multi-daylight) injection mould, which are disposed parallel to each other, movable relative to each other by means of racks fixed to the outer plates, which racks engage with a pinion attached to the centre plate. The known arrangement of the racks or the pinion in the centre region of the plates is disadvantageous in that removal of the injection moulded part is only possible from the two unobstructed sides. Naturally this leads to a restriction of the production process, since universal use of such injection moulds is not possible. The object of the invention is therefore to improve the applicability of the injection mould. To this end it is provided for the racks (6, 7) and the associated pinion (8) to be disposed in the corner region of the corresponding plates (1, 2, 3). By means of the invention it is now possible to remove the injection moulded parts from practically any side, so that automation of the removal process, for example with automatic removal equipment, can be carried out without restriction. <IMAGE>

Abstract: The patent describes a method and apparatus for securely distributing an initial Data Encryption Algorithm (DEA) key-encrypting key by encrypting a key record (consisting of the key-encrypting key and control information associated with that key-encrypting key) using a public key algorithm and a public key belonging to the intended recipient of the key record. The patent further describes a method and apparatus for securely recovering the distributed key-encrypting key by the recipient by decrypting the received key record using the same public key algorithm and private key associated with the public key and re-encrypting the key-encrypting key under a key formed by arithmetically combining the recipient's master key with a control vector contained in the control information of the received key record. Thus the type and usage attributes assigned by the originator of the key-encrypting key in the form of a control vector are cryptographically coupled to the key-encrypting key such that the recipient may only use the received key-encrypting key in a manner defined by the key originator. 
     The patent further describes a method and apparatus to improve the integrity of the key distribution process by applying a digital signature to the key record and by including identifying information (i.e., an originator identifier) in the control information of the key record. The integrity of the distribution process is enhanced by verifying the digital signature and originator identifier at the recipient node.

Abstract: The invention relates to a device for generating digital signals, particularly control signals for a radio transmission system which essentially recur within a predeterminable time frame. The device is intended to rule out the possibility for generating a multiplicity of control signals with a high time resolution and flexibility in application in a simple manner. It is proposed that the variations in the control signals can be derived from signal variation descriptions which can be stored in a random-access memory (11), the digital signals being selected by means of an address device (12) associated with the random-access memory (11). In an advantageous embodiment, the starting time of the digital signals can be predetermined by comparing the contents of a comparison counter (13), clocked at a multiple of the clock of the digital signals, with the contents of a timing table (T) which can be stored in the random-access memory (11).
