摘要： An input circuit includes: a comparator; first and second delay circuits; a selector; an input buffer; and a holding circuit. The comparator compares the leading and/or trailing edges of a data signal, supplied from the input buffer, to an edge of a clock signal on which the data signal is intended to be latched. Based on the results of the comparison, the first and second delay circuits delay the clock signal for respectively predetermined amounts of time. If the data signal is logically high, then the selector selects a delayed clock signal supplied from the first delay circuit. Alternatively, if the data signal is logically low, then the selector selects another delayed clock signal supplied from the second delay circuit. Then, the delayed clock signal, selected by the selector, is latched in the holding circuit. The input circuit with such a configuration prevents skewing from being caused by a difference in length between the transition interval of the data signal from H into L level and that of the data signal from L into H level. As a result, data can be transferred at a much higher speed even if the clock frequency is very high.

摘要： A semiconductor memory having ports, each of which conducts exclusively a writing or reading operation, by which the access operation can be speeded up when cells at the same row address are accessed simultaneously through two ports. A current-carrying capability of a write access transistor making up a memory cell is lowered relative to a current-carrying capability of a read access transistor within a range capable of finishing the writing operation.

摘要： A power-saving network unit, which is connected to a network made up of a plurality of power-saving network units, includes: network monitoring means; network information memory; power-saving mode setting means; peripheral I/O interface; and digital processor. The network monitoring means monitors a topology of the network, or the interconnection relationship among the power-saving network units. Every time the network has been modified, the network monitoring means stores the modified network topology on the network information memory. The power-saving mode setting means receives the network information stored on the network information memory. If the power-saving network unit is a master or relay node in the network, then the power-saving mode setting means locks the peripheral I/O interface and digital processor of the power-saving network unit to the normal operation mode and prohibits these sections from entering the power-saving mode.

摘要： A semiconductor integrated circuit includes receiver, potential sensor and output fixing circuit. The receiver receives a differential signal that has been transmitted through a twisted pair of signal lines, and outputs a signal in accordance with the differential signal. The potential sensor senses a variation in in-phase potential of the differential signal transmitted through the twisted pair. And the output fixing circuit fixes an output of the receiver at a certain value if the variation sensed by the potential sensor is equal to or greater than a predetermined level. In this configuration, once the variation in the in-phase potential of the differential signal has reached the predetermined level, the output of the receiver is fixed at the certain value. Accordingly, even if the receiver operates erroneously due to the in-phase potential variation, the erroneous output of the receiver is not supplied to the next stage like a digital section.

摘要： A current driver, a common mode voltage monitoring circuit and a current compensator are provided to drive a twisted pair cable, which is made up of two signal lines coupled to a terminal bias voltage through respective terminal resistors. The common mode voltage monitoring circuit monitors a difference between a common mode voltage of the twisted pair cable and a supply voltage level for the current driver. And the current compensator is coupled to the twisted pair cable to compensate for an output current of the current driver in accordance with a result of monitoring performed by the common mode voltage monitoring circuit. If the current driver has decreased its current drivability due to a drop of the supply voltage level of the current driver or a variation in the common mode voltage of the twisted pair cable, then the current compensator compensates for the decrease. Thus, the current driver can continuously operate in a broad voltage range to supply a constant current.

摘要： The level of a differential signal is determined such that a system, utilizing the level determined, can operate stably enough even if the intermediate potential of the signal changes. A comparator receives, as differential input, a differential signal to be transmitted. During a level determination interval, a sampler/level determiner samples the output of the comparator a number of times, and outputs a most frequently sampled value as the level of the differential signal.

摘要： Accurate control of the tension of a wire electrode in a wirecut electrical discharge machine is achieved by eliminating a direct-current (DC) component from a speed difference signal between a braking section and a recovery section of the machine. The DC component of the speed signal which is eliminated is associated with the stretching of the wire electrode while under tension. As a result, the tension can be maintained constant dynamically as well as statically, thereby improving machining accuracy.
