Publication number: 20060020823Abstract: After power-on of an MFP, a data protecting apparatus receives an encryption key from a host server via a network I/F, stores the received encryption key in an encryption key storage unit, delivers the encryption key to a decryption key generation unit, and stores a generated decryption key in a decryption key storage unit. Subsequently, an HDD controller reads out master data that is written in an HDD. A data decryption unit decrypts the master data, using the decryption key stored in the decryption key storage unit. A REF data generation unit generates reference data. A data comparator compares the decrypted master data with the generated reference data. If the decrypted master data coincides with the reference data, the data protecting apparatus determines that the encryption key is normal. If they do not coincide, the data protecting apparatus determines that the encryption key is abnormal.Type: ApplicationFiled: July 9, 2004Publication date: January 26, 2006Inventor: Shigeru Morino

Patent number: 5592210Abstract: A method and an apparatus for driving an edge emission type line head having a plurality of edge emission type EL elements grouped in blocks. Each group of the edge emission type EL elements has a channel electrode connected to a channel driver and has a common electrode connected via a matrix circuit to common terminals of a common driver. The channel driver outputs voltages while the common driver outputs alternately a positive and a negative high voltage. If something happens to stop the function of the line head in operation, the output of the common driver is stopped after a pair of a positive and a negative high voltage is output by one common terminal, or after one-line output is effected by the common driver. This helps prolong the service life of the edge emission type EL elements constituting the line head.Type: GrantFiled: October 27, 1993Date of Patent: January 7, 1997Assignee: Kabushiki Kaisha TECInventors: Kei Hara, Shigeru Morino
