Patent JP-2002246670-A (JP)
Title: Actuator and manufacturing method therefor
Inventor: AMI TAKAAKI
IPC: H01L41/22
Filed: 2001-02-20
Abstract: PROBLEM TO BE SOLVED: To provide an actuator which can perform an expansion/contraction operation at comparatively fast response speed with good controllability by electric stimulus, can obtain displacement that is sufficiently larger than a piezo element, can perform the expansion/contraction operation in a specified direction, does not need a solution supply system and has the characteristic of good balance. SOLUTION: A KTiNbO5 thin film being an interlayer compound is formed on a (001) conductive SrTiO3 substrate 1, ions are exchanged and a HTiNbO5 thin film is formed. Trimethyl stearyl ammonium ions (TMSA) are intercalation with respect to the HTiNbO5 and therefore a (TMSA) TN thin film 2 is formed. An upper electrode 3 is formed on the (TMSA) TN thin film 2 and a lower electrode 4 is formed at the back of the SrTiO3 substrate 1 so as to constitute the thin film actuator. Thus, the expansion/contraction operation is performed by applying voltage between the upper electrode 3 and the lower electrode 4.

Title: Scheduling method for transaction
Inventor: HOWARD M BROWN
IPC: G06F13/36
Filed: 2001-02-28
Abstract: PROBLEM TO BE SOLVED: To maximize a waiting time for an isochronous transaction(TR), and to minimize a waiting time for an asynchronous TR. SOLUTION: An assigned shared bus time is divided into plural frames with the same length (a step 502), and when a bus request is received in the present frame, whether or not the bus request is related with an asynchronous TR is discriminated (504). When it is discriminated that the bus request is related with the asynchronous TR, the bus request is processed (508), and in the other case, a bus request related with an isochronous TR is processed (506). When the bus request related with the isochronous TR is received during; the processing of the asynchronous TR, a bus related with the isochronous TR is inputted to a queue. The asynchronous TR is given priority until the present frame time is ended. When a new frame is started, the isochronous TR inputted to the queue is processed before the asynchronous TR of the frame is performed (512).
