摘要： Disclosed is a secure remote access system for improving convenience of a user by utilizing a storage device including an anti-tampering device as a user authentication device in the secure remote access system for making access and execution of job while a user is making the encrypted communication to a server from an unspecified client. Usability can be improved and thereby the job executing function can be used smoothly at the internal and external sides of the working office by providing a server client system where the server can be manipulated remotely by distributing a storage device loading the authorized anti-tampering device to users, connecting the storage device to unspecified clients by users, and using the authentication information and application stored in the storage device. A remote access system having improved security and convenient during usage of client from the user can also be provided by reducing the secret information remaining in the manipulated client.

摘要： An optical transceiver operable in multi transmission rates is disclosed. The optical transceiver includes an EDC to compensate the deformation appeared in the input signal due to the dispersion of the optical transmission line. The EDC operates as the transversal filter for higher transmission rates, while it operates as the low-pass-filter for lower transmission rates. In medium transmission rates, the EDC passes through the input signal.

摘要： There is a need for providing a communication data processor easily adaptable to network configurations required for industrial Ethernet. The apparatus successively analyzes received packets. The apparatus uses a register to determine whether or not to transmit the received packet as transmission data to another port. Rewritable memory saves a program code that provides control for analyzing a reception packet and generating a transmission packet. The apparatus is capable of complying with various communication protocols by changing the program code.

摘要： A high-frequency circuit device includes a substrate and a high-frequency circuit. The high-frequency circuit is provided on the substrate and has a signal line. The signal line is configured with a slot line provided by electrodes that are arranged side-by-side with a space therebetween on the substrate. The slot line can facilitates circuit design compared to a microstrip line and has significantly low conduction loss compared to a coplanar line, and can improve the Q-value of the high frequency circuit. This can provide an improved high-frequency circuit device having small phase noise. The high-frequency circuit device, which also serves as an oscillator, employs a slot output and thus can provide an advantage of better continuity for a class-B push-pull amplifier that operates more efficiently than a class-A one.
