Abstract: An inter-roller conveyance control device conveying an object to be conveyed between a speed shaft roller driven by a speed shaft motor and a tension shaft roller driven by a tension shaft motor while providing tension to the object includes a gain table that stores a plurality of pairs of a conveyance condition variable changing while the object to be conveyed is conveyed and affecting an appropriate value of a control parameter and a control parameter candidate value that is an appropriate control parameter where, when the conveyance condition variable is changed, the device performs calculation on the basis of the conveyance condition variable and a gain calculation result and writes, into the gain table, the control parameter candidate value and the conveyance condition variable in association with each other when the calculation is completed.

Abstract: The roller-to-roller conveyance control apparatus includes an amplitude target setting unit that sets an amplitude target value of the tension deviation; an adjustment execution command generation unit that provides a command to adjust the control gain; an adjustment manipulated-variable output unit that outputs an adjustment manipulated variable; a manipulated-variable amplitude determination unit that increases the amplitude of the adjustment manipulated variable until the amplitude of the tension deviation becomes larger than the amplitude target value; and a control-gain calculation device that calculates the control gain from the amplitude and the vibration period of the tension deviation. A tension-shaft speed controller controls a tension-control-shaft motor on the basis of the line speed reference and the adjustment manipulated variable during the adjustment of the control gain.

Abstract: A server transmits distribution communication blocks to a relay client and other clients through the Internet. The communication blocks include at least addresses and pieces of distribution information of the relay client and the other clients. The relay client obtains the pieces of distribution information from the distribution communication blocks, and circulates the communication blocks in which distribution results are set to a client next in the order on the basis of the addresses. The last client that receives the distribution communication block transmits it to the relay client. The relay client relays the distribution communication block back to the server.

Abstract: Encrypted contents information is received by a contents information receiving unit, and stored by a first storing unit. Each time a request to output stored contents information is input in a contents outputting device, a distribution request for a decryption key required to decrypt the contents information is transmitted from a key distribution request transmitting unit. A key receiving unit receives the decryption key transmitted in response to this request, and an encryption key used to perform an encryption process, which cannot be decrypted with the decryption key, for the contents information. A contents outputting unit decrypts and outputs the contents information. After the contents information is output, the encryption process using the encryption key, which is received along with the decryption key, is performed for the contents information by an encryption processing unit, and the contents information is again stored by a second storing unit.

In this electronic mail system, if an attached file is added to electronic mail sent from a mail client, being a sender, an attached file separating section separates the attached file from the electronic mail. An attached file transferring section transfers the attached file separated from the electronic mail by the attached file separating section to an FTP server. A store location information adding section adds store location information indicating a location where the attached file transferred by the attached file transferring section is stored to the electronic mail. The electronic mail to which the store location information has been added is sent to a receiver mail server.

Abstract: A color display device has a single light guiding plate, and first, second and third light sources that respectively independently exhibit three primary colors. On a one end surface of the light guiding plate there are disposed the first and second light sources that exhibit two different ones of the three primary colors. On the other end surface side of the light guiding plate there is disposed the third light source that exhibits the remaining one primary color. Since the light guiding means is needed only one in number, the structure can be simplified and miniaturized. Also, on the one end surface of the light guiding means there are disposed, of the three light sources exhibiting the three primary colors, the first and second light sources that exhibit two different ones of the three primary colors. And, on the other end surface side of the light guiding means there is disposed the third light source that exhibits the remaining one primary color.
