A distributed information processing system which includes a server having a resume-request processor and clients having resume-request units or processor. An user at the client site operates a resume switch to save an operation state of the client in the server's magnetic disc, and resume it from the server's magnetic disc. The operation state includes contents of the main memory, contents of the display memory, values of the I/O registers for peripheral devices, and information about the file of the server being used by the application program run by the user. The user is able to use any client of the system in the same situation including a connection state between the file and the application program as before.

A spatial position x′ of each ultrasonic transducer is accurately obtained for each probe in consideration of each edge transducer gap, and a delay time T(x′(n)) and a weighting coefficient W(x′(n)) are calculated on the basis of the position of each ultrasonic transducer. A control unit executes ultrasonic transmission/reception by using the calculated delay times and weighting coefficients to realize a suitable acoustic field with high deflection angle accuracy, small sidelobes, and the like as compared with the prior art.

According to one embodiment, an ultrasonic probe has a laminated structure of an acoustic matching layer, transducer layer with arrayed transducers, and backing layer. A transmission/reception unit transmits and receives ultrasonic waves to and from an object via the transducers. A control unit controls the transmission/reception unit to synchronize ultrasonic-wave generation by a specific transducer of the transducers with ultrasonic-wave reception by a different transducer. A phase shift detection unit detects a phase shift between an output signal from the transmission/reception unit and a reference signal, the output signal corresponding to synchronization between the ultrasonic-wave generation and the ultrasonic-wave reception.

The plurality of piezoelectric elements are arrayed. The first electrode is provided on the emitting surface side of the plurality of piezoelectric elements. The plurality of second electrodes are respectively provided on the rear surface sides of the plurality of piezoelectric elements. The plurality of stacked flexible printed circuit boards respectively include a plurality of terminals. The plurality of connection portions electrically connect the second electrodes to the terminals. At least one of the flexible printed circuit boards extends longer than the flexible printed circuit board serving as an upper layer.
摘要:
An ultrasound transducer according to an embodiment has two-dimensionally arranged ultrasound vibrators. A wiring board block is a laminate of wiring boards which are arranged along the row direction in the arrangement. The wiring board has a first surface facing a rear surface of the ultrasound vibrators and a second surface on its opposite side. First connection parts are provided on the first surface corresponding to the arrangement, and are conducted with back electrodes of the vibrators. Second connection parts are provided on the second surface, and are provided corresponding to the first connection parts. Connecting leads establish conductivity between the first and second connection parts through a fourth surface which is perpendicular to the second and third surfaces. Electronic circuits are connected to the second surface of the wiring board block, and are conducted with the second connection parts.

摘要:
A time period which is expended since a request for the authentication of the validity of a public key certificate till the authentication of the validity, is shortened. A certificate validity authentication center VC periodically searches for and verifies paths which extend from a bridge certification authority CAbridge to individual terminal admitting certification authorities CA, and it registers the paths whose verifications have held good, in a path database in association with the respective terminal admitting certification authorities CA. Besides, in a case where the request for the authentication of the validity of a certificate has been made by an end entity EE, whether or not a path associated with the terminal admitting certification authority CA which admits the end entity, and a path associated with the terminal admitting certification authority CA which has issued the certificate being a subject for the request are registered in the path database is checked, and the subject certificate is judged valid only when both the paths are registered.
