Abstract: Firmware FW1 and FW2 is separately stored in a non-volatile memory, in which a boot code for start-up and a restoration code are stored, and a first magnetic disk. A copy of the firmware FW1 stored in the non-volatile memory is stored in the first magnetic disk, and a copy of the entire firmware FW1 and FW2 stored in the first disk medium is stored in the second magnetic disk. When an error occurs during firmware update, upon next power-on, whether the volatile memory, the first magnetic disk, and the second magnetic disk are normal or abnormal is determined, and valid firmware is read and allocated to the volatile memory so as to perform start-up by a start-up mode corresponding to the determination contents.

Abstract: Data in a storage medium is scanned while a storage device is in an idle state. A proportion of scanned data in entire data in the storage medium is compared with a threshold value. If the proportion of the scanned data is less than the threshold value, an unscanned data in the storage medium is scanned during a time interval between commands received by the storage device from outside. The process is repeated until the proportion of the scanned data is equal to or more than the threshold value.

Abstract: According to one embodiment, a disk drive includes a medium scanner and a threshold manager. The medium scanner measures the write count of each head with respect to a disk. The medium scanner executes a read verify process by which data is read out from the disk, during idle state, when the write count is equal to or larger than a predetermined threshold value. The medium scanner rewrites the recovered data to the disk, if a read error occurs and the error is recoverable. The threshold manager initially sets the write count threshold value of each head in accordance with the head performance, and dynamically changes the write count threshold value in accordance with the error rate when the device is in operation.

Abstract: To provide a medium scan method which can be executed for a suitable region at suitable timing, a disk device comprises a storage medium for storing information, a writing unit for writing information to the storage medium by request from an upper device such as a host computer or the like, a medium monitoring unit for monitoring the state of the storage medium, and a medium scan determining unit for determining whether or not to require medium scan for the storage medium.

Abstract: Respective nodes N1 to N3 only detect a carrier, and the node N3 sets a random time between a time after a certain period of time t1 and a time until a certain period of time t2 after the carrier of data D11 is gone as a waiting time so as to transmit data within this waiting time. The node N2 transmits ACK data D12 with respect to the data D11 to the node N1 before the certain period of time t1 after the carrier of the data D11 is gone. The node N3 detects the carrier of the ACK data D12 and again sets a random time after the certain period of time t1 until the certain period of time t2 to transmit the data.

Abstract: Nodes (N1 to N3) include MTU length calculation sections (31 to 33) which multiply baud rates (D21 to D23) of communication parameters (D11 to D13) set based on results of negotiation with other nodes (N1 to N3) by a communication regulated time used in timer control for transmission/reception, and which calculate MTU lengths as maximum packet lengths of the packets based on the multiplication results so that transmission times of the packets for the destination nodes are equal to each other, and also include communication control sections (21 to 23) which divide data to be transmitted to destination nodes into packets having the calculated MTU length to transmit the packets.

Abstract: A method of separating and recovering 18F from 18O water at high purity and efficiency while maintaining the purity of the 18O water. By using a solid electrode (1) as an anode and a container (electrodeposition vessel) (2) made of platinum as a cathode, 18F in a solution (4) is electrodeposited on the solid electrode surface by applying a voltage. Then, by using the solid electrode (1) on which 18F is electrodeposited as a cathode and a container (recovery vessel) (5) holding pure water therein as an anode, 18F is recovered in the pure water by applying a voltage of opposite polarity to that of the electrodeposition. In this process, little 18O water is lost. The initial concentration of the 18O water is maintained even after the electrodeposition of 18F, so that the 18O water can be repeatedly used as an irradiation target for production of 18F.

Abstract: A digital radio communications receiver for predicting correctly a frame structure and assuring correct synchronization.

Abstract: A digital radiocommunication receiver includes a demodulation device for a one-symbol unit for detecting a received signal in a unit of one symbol and for outputting a received bit sequence. The demodulation device includes a maximum likelihood sequence estimation for outputting a received bit sequence from a received signal sequence concerning a plurality of symbols. A sync word detecting device determines the detection or nondetection of a sync word from the received bit sequence outputted from the demodulating device for a one-symbol unit. A timing of the bit sequence is made to coincide with a timing of the bit sequence outputted from the demodulating device involving the maximum likelihood sequence estimation. A synchronization controlling device determines a timing of a received frame and controls, as required, a transmission timing using information on the sync word detection.
