Abstract: Stream data is transmitted from a distribution server to a client without any loss of data. The capacity of a reception buffer to be prepared at the client can be made small and the network bandwidth necessary for data redistribution can be narrowed. A relay server interposed between the distribution server and client buffers stream data in an auxiliary storage device. When the relay server or client detects a loss of stream data, a redistribution request is transmitted to the distribution server or another relay server at the preceding stage.

The device also includes an upstream-side trailing edge detector disposed on an upstream side of the rollers for detecting a trailing edge of the recording medium, a downstream-side trailing edge detector disposed on a downstream side of the rollers for detecting the trailing edge of the recording medium, and a skip warning region determination unit for determining whether or not the trailing edge of the recording medium is located in a skip warning region.

Abstract: A carriage driving apparatus that drives a carriage of a printer or the like by a motor and a motor control method for controlling the motor can substantially eliminate variation in control accuracy among individual apparatuses. Each set of various parameters are determined with respect to each ultimate target speed of the carriage and each moving direction, and contained in a table. Three kinds of tables, i.e. a table for heavy load, a table for light load and a table for standard load in accordance with the difference in load applied to individual drive systems of the carriage, as well as one kind of table for low temperature are prepared and stored on a ROM. It is determined which of the three kinds of tables should be selected at normal temperature by actually driving the carriage in the final step of the manufacturing process.

Abstract: A data transmitter and a data receiver generate respective synchronous signals from a common reference signal. The data receiver adjusts a phase of a first clock signal using each one of one-bit data signals each consisting of a single bit of received parallel data, so that a setup time and a hold time are ensured for the each one-bit data signal, and loads each one-bit data signal into a data buffer in accordance with the adjusted clock signal. Then, the data receiver reads the data held in the data buffer, in accordance with a second clock signal and in synchronization with the receiver synchronous signal. A memory position where the data signal is to be loaded is initialized when a training pattern transmitted in synchronization with the transmitter synchronous signal is detected.

Abstract: To provide a cache-tag control method capable of correcting an error and capable of keeping a high-speed operation of a system at the same time. A true-tag with a parity code attached and a shadow-tag having an inverted polarity of the true-tag are stored respectively in separate addresses within a cache tag-RAM. At the time of retrieving the tags, both the true-tag and the shadow-tag are checked respectively to see whether there is an error in each tag. When an error has been detected, a hit decision is made by using a tag in which there is no error. Further, data within the cache tag-RAM is updated by using the tag in which there is no error, thereby correcting the error.

Abstract: A cache control apparatus for an information processing system having a cache memory with a plurality of ways is disclosed, in which the hardware amount is reduced and the delay of the response time is minimized. At the time of cache access, each way is indexed by time division, and when updating the cache, a way to be updated is designated thereby to update the cache tag and the cache data. The data indexed by time division can be judged for a hit each time of indexing or alternatively, the data of all the ways are judged for a hit after being held in a buffer. The data indexed by time division is sent to the reader as response without regard to the way, and when a miss is judged, a cancel signal is sent thereby to minimize the access time delay. Further by predicting the address of a way, the access time can be further improved.

Abstract: An apparatus of this invention includes first and second supply rolls of wrapping film sheets. The film sheet is fed from first supply roll to a wrapping machine. The distal end of the film sheet of the second supply roll is partially fixed by an adhesive tape. In this state, the film sheet cannot be fed from the second supply roll. The second supply roll can be rotated in the forward or reverse direction. The apparatus also includes a knife for cutting the adhesive tape of the second supply roll. When the remaining length of the film sheet fed from the first supply roll becomes short, the knife is brought into contact with the outer surface of the second supply roll. By utilizing the rotation of the roll, the knife is inserted under the distal end of the film sheet of the second supply roll. Thereafter, the knife is moved along the outer surface of the second supply roll in the axial direction thereof, thereby cutting the adhesive tape of the second supply roll.
