Abstract: PURPOSE:To reduce the number of components of an optical disk driving device and to enable grasping the tendency of individual malfunctions by diagnosing whether each part is normally being operated or not, when the optical disk capable of writing/reading data is driven. CONSTITUTION:A CPU 16 is built in the optical disk driving device, thereby a driving system control/diagnostic data detecting circuit 13, a signal process system control/diagnostic data detecting circuit 14 and an interface control/ diagnostic data detecting circuit 15 are controlled, and also the diagnostic data from these circuits are preserved in a RAM 17. Also, the diagnostic data are read out in accordance with the instruction from a host computer 20 and supplied to the computer 20 then displayed on a display device such as a CRT, etc. Thus, a variance of components degree of deterioration, limit of life, etc., of the optical disk driving device are informed to the user for performing the replacement/repair of the components and a backup of the data, and the like.

Abstract: PURPOSE:To make the writing and reading-out states of data distinguishable by setting the successively turning-on direction of a plurality of displaying sections when data are written on a disk recording medium opposite to that when data are read out from the recording medium. CONSTITUTION:A host computer 3 instructs a disk device 1 to perform writing/ readout on a disk loaded on the device 1 by sending a command to the controller 2 of the device 1. Light sources La, Lb, and Lc are composed of LEDs and fitted to the device 1 in a line as a displaying section. At the time of writing data, the light sources are successively turned on in the order of Lc, Lb, and La in such a way that, when one of the light sources is turned on, the other light sources are turned off. At the time of reading out data, on the other hand, the light sources are turned on in the order of La, Lb, and Lc in such a way that, when one of the light sources is turned on, the other light sources are turned off.

Abstract: PURPOSE:To improve the processing speed and to reduce the cost by providing an exclusive arithmetic unit so as to control an address of a source memory and an output memory and using a DMA(direct memory access) so as to write a picture data subject to arithmetic processing to the output memory at a high speed. CONSTITUTION:A picture data in data such as picture data and processing data supplied from a data storage section 10 to an arithmetic section 30 is written in a source RAM 33 and the processing data is written in a RAM of a microcomputer 31. When the calculation of the picture data is needed, the readout address of the source RAM 33 and the write address of the output RAM 34 in the exclusive arithmetic unit 32 are controlled. Then the picture data written in the prescribed address of the source RAM 33 is written in the prescribed address of the output RAM 34. That is, the picture data subject to arithmetic processing is written in the output RAM 34 at a high speed.

Abstract: PROBLEM TO BE SOLVED: To reduce power consumption. SOLUTION: An initiator regulated by NFCIP-1 transmits attribute information expressing its own communication capacity and receives an attribute information expressing communication capacity of a target from the target. The initiator turns off output of electromagnetic waves for a predetermined period after transmitting one data based on the received attribute information. The predetermined period is a time not more than an initial delay time that is the minimum time required for an apparatus trying to start data transmission/reception to confirm that no electromagnetic wave is outputted. This invention can be applied to an NFC communication apparatus, for instance. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To reduce power consumption. SOLUTION: An initiator prescribed by NFCIP (Near Field Communication Interface and Protocol)-1 transmits attribute information indicating communication ability of itself as well as receives attribute information indicating communication ability of a target from the target. When the received attribute information indicates that the target has communication functions in a power saving mode, the initiator reduces power of an electromagnetic wave to be outputted after receiving the attribute information. The present invention is applicable, for example, to an NFC communication device. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To enable communication by which a user can enjoy advantages of a plurality of communication protocols. SOLUTION: An NFC (number of fine codes) communicating part 51 of communication equipment 1 performs communication by an NFC with an NFC communicating part 61 of communication equipment 2 to thereby recognize that communication (BT communication) by Bluetooth (R) can be performed, further exchanging BD addresses of BT communicating parts 52 and 62 as communication information necessary for the BT communication. The communication equipment 1 and 2 switches (performs overhand) communication by the NFC between the NFC communicating parts 51 and 61 to BT communication between the BT communicating parts 52 and 62 to perform the BT communication on the basis of the BT addresses of the BT communicating parts 52 and 62.

Abstract: PROBLEM TO BE SOLVED: To accelerate access to data at the time of data reproduction corresponding to a magnetic tape. SOLUTION: In the case of recording application data to a tape cassette provided with MIC, write is performed from the head of the application data to be recorded on the magnetic tape to the area in a prescribed size of the MIC. Thus, in the MIC, at least management information positioned at the head of the application data can be stored. Then, at the time of reproducing the application data from such a tape cassette, since just the management information stored in the MIC is utilized, the need of the time to access the management information recorded on the magnetic tape is eliminated.

Abstract: PROBLEM TO BE SOLVED: To reduce the cost of communication equipment (remote memory interface) and to improve flexibility to a design change. SOLUTION: A data processing means encodes transmission data and decodes reception data through software processing. For instance, the data processing means is constructed by using a general purpose microcomputer to decode the reception data and encode the transmission data through software processing, a dedicated IC thereby does not have to be designed and mounted, and miniaturization and cost reduction in the communication equipment are promoted. It is also possible to easily correspond to the changes of an encode/decode method, a communication speed and other communication specifications by changing software.

Abstract: PROBLEM TO BE SOLVED: To perform efficiently load/unload operation based on a recording position of a file on a magnetic tape and to keep a real time characteristics reproduced data. SOLUTION: When recording operation is started (S1101). buffering is started for a buffer area E1 and data is recorded in a magnetic tape with a division unit. After that, a processing process is selected based on whether a device area #2 is made or not (S1102-S1104). For example, when the device area #2 is not made, the device area #2 is made when a recording position reaches a central part of a magnetic tape (S1106). And it is discriminated whether transfer of a file from a computer device is finished or not, when it is discriminated that transfer of a file is not finished, as same files are recorded by holding the device area #2 between them, joint data is recorded in a joint data area (S1107-S1108).
