Title: Magnetic card reader
Inventor: ITO HISAO
IPC: G06K19/06
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic card reader which can surely prevent unauthorized use of a magnetic card. SOLUTION: When a magnetic card 10 where fixed data are written in a magnetic recording layer so that it is not possible to be rewritten is supplied to a magnetic card reader 30, a magnetic head 21 reads card information. When a control part 22 determines that the card can be used, new remaining amount information is recorded in the card. Remaining amount information is recorded by destroying fixed data written in the magnetic recording layer of the card 10, which cannot be rewritten, by a destruction means 21.

Title: Data transmission system
Inventor: KANEKO OSAMU
IPC: H04L12/40
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To provide the data transmission system in which re-occurrence of congestion is suppressed. SOLUTION: A client terminal equipment 20 sends a plurality of consecutive I frames to a server terminal equipment 10 at a prescribed time interval. The server terminal equipment 10 sends a receive not ready(RNR) frame to the client terminal equipment 20 as soon as congestion takes place. Upon the receipt of the RNR frame, the client terminal equipment 20 interrupts the transmission of the I frames. The server terminal equipment 10 sends a receive ready(RR) frame to inform release of congestion to the client 20 when the congestion is released. Upon the receipt of the RR frame, the client 20 restarts transmission of the I frames at a time interval longer than the prescribed constant time interval.
