Abstract: A metal foil has a cathode surface on which no linear indentations exist when viewed microscopically, a production method for the same, and a processing method for an electrodeposition drum used for the same. A surface of the electrodeposition drum for producing the metal foil is irradiated with a laser to process this surface into a pattern of repeated curved shapes including a plurality of dot-shaped dents or the like. With this, the pattern of repeated curved shapes is formed on the surface of the electrodeposition drum. The electrodeposition drum thus processed is used as a cathode, supply of electricity is provided between the electrodeposition drum and an anode plate that are soaked in an electrolytic solution to electrodeposit metal on the surface of the drum with an electrolytic reaction, and thereafter, the metal is peeled off from the electrodeposition drum, thereby yielding the metal foil.

Abstract: There is provided a packet transmission apparatus, system and method that are implemented in an apparatus generating a packet to send out packet generated toward another device via a network bus, including: generating a first packet having a first header and contents data; inputting a data string of the first packet to a buffer from its head successively; determining whether the network bus is available in case where a predetermined data sending condition is satisfied; reading out contents data that is input to the buffer and that is not yet read out from the buffer, in case where the network bus is available; generating a second header on the basis of a size of the contents data read out and the first header; adding the second header to the contents data read out to generate a second packet; and outputting the generated second packet to the network bus.

Abstract: There is provided a time stamp correction apparatus for being used in an apparatus which receives a packet including real time data and a time stamp based on network time from a network and reproduces the real time data on the basis of the time stamp, the time stamp correction apparatus including: receiving a first packet including the real time data and a first time stamp; successively generating the network time according to synchronous information input from the network; calculating a difference between time by the first time stamp and the network time; successively generating local time; generating a second time stamp based on the difference and the local time; generating a second packet by adding the second time stamp to the real time data; storing the generated second packet into a buffer unit; and conducting output control on the second packet on the basis of the local time.
