Further, the metal chassis part (12a) is used for a section of the chassis (12) including a predetermined distance from an inverter circuit (driving circuit) (26) for the cold cathode fluorescent tubes (20, 21) in the longitudinal direction of the cold cathode fluorescent tubes (20, 21) and the resin chassis part (12b) is used for the section beyond the predetermined distance.

Abstract: In one embodiment of the present invention, a method for driving a liquid crystal display device is disclosed which includes: combining liquid crystal panels a and b with one another, each of which displays an image in accordance with a video image source, wherein, when the images respectively displayed on the liquid crystal panels are combined with one another so that a signal image is displayed, the images that are different from each other are switched with one another at a preset interval. As a result, a phosphor burn-in on a display screen is difficult to occur, even when an identical image is displayed continuously for an extended period of time.

Abstract: An encryption/decryption system capable of supplying data only to a user making a request. A computer encrypts data with a common key, encrypts the common key with a public key, and transmits the encrypted data and the encrypted common key. A copy machine receives these data, encrypts challenge data with the public key, and transmits the encrypted challenge data to an IC card. The IC card decrypts the encrypted challenge data with a private key, and feeds the decrypted challenge data back to the copy machine. The copy machine transmits the IC card an encrypted common key of reception data offering decrypted challenge data identical to the original challenge data. The IC card decrypts the encrypted common key and feeds the decrypted common key back to the complex copy machine. The complex copy machine decrypts the encrypted data with the common key.

Abstract: A data transfer system for transfer target object data from a data transmission apparatus to a data reception apparatus via transfer paths. The data transmission apparatus judges whether or not encrypting operation for the transfer object data is necessary on the basis of attributes of the transfer paths, encrypts the transfer object data when the encrypting operation for the transfer object data is judged to be necessary, and transmits either the transfer object data or the encrypted transfer object data via the transfer paths to the data reception apparatus. The data reception apparatus receives either the transfer object data or the encrypted transfer object data from the data transmission apparatus; judges whether or not decoding operation for the received transfer object data is necessary, and decodes the received transfer object data when the decoding operation for the received transfer object data is judged to be necessary.

Abstract: A service history generation section employs stored information to generate a service history indicating whether a pertinent server can provide a service for an arbitrary client device and an arbitrary server. A history requesting section requests the server to notify a service history via a network. Upon receiving the request from the client device, a history notification section notifies a service history to the requesting source client device. A server selection section then displays the service history received from the server as a UI image for a user, and in accordance with the user's manipulation, selects an appropriate server for the execution of the service.

Abstract: A data transmission control information acquisition section generates data transmission control information based on control information exchanged between applications of a data transmitter and a data receiver before data transmission is started. A data transfer control section determines a bandwidth to be used by the data transmission, transmission start time, etc. in a shared transmission medium in a unified manner based on the data transmission control information and current bandwidth use conditions, and transmits the thus-determined information to the data transmitter. The data transmitter transmits data to the data receiver via the transmission medium under unified management.
