Abstract: The present invention aims to provide a field effect transistor which inhibits an aggregation of silicon atoms attendant on heat treatment and has stable source/drain shapes. The field effect transistor according to the present invention is manufactured using a substrate on which a silicon layer, an buried oxide film (BOX film) and an SOI layer are stacked in order. The field effect transistor has an element isolation layer formed in the SOI layer and further includes visored portions provided so as to cover angular portions on the main surface side of an activation layer defined by the element isolation layer.

Abstract: In order to prevent silicides from getting under side walls when the silicides are formed over MOSFET formed over an SOI substrate, trenches are defined in the SOI substrate and side walls are formed over the trenches, whereby the silicides are blocked so as not to get under a gate insulator with a lower portion of each side wall as a structure convex in a downward direction of the substrate. Thus, an increase in gate withstand voltage, a decrease in gate leakage current and control on a short channel effect are achieved.

Abstract: A demodulator device of the present invention receives a propagation signal including a plurality of channel signals multiplexed with each other, that is modulated by using an orthogonal code sequence, through different propagation paths. The demodulator device includes propagation path estimators for performing operations including propagation path estimation and demodulates the received propagation signal by subjecting outputs of the propagation path estimators to multi-path combination. More specifically, for information obtained by correlators corresponding to operations, the demodulator device performs the multi-path combination by combining results of multiplications of the outputs of the propagation path estimators for correlation values and then separate the plurality of channels.

Abstract: An echo canceling apparatus includes a long-response echo canceler that removes an echo of an incoming signal from an outgoing signal by operating on a most recent segment of the incoming signal, stored in a tapped delay unit. The apparatus has a control unit that calculates a cancellation characteristic for each tap of the tapped delay unit. The cancellation characteristics are used to select a subset of taps corresponding to a changing component of the echo, the subset being empty if there is no changing component. A short-response echo canceler, operating on the outputs of the selected taps, cancels the changing component of the echo left uncanceled by the long-response echo canceler. Alternatively, the step gain of the selected taps is increased. The short-response echo canceler is preferably disabled in the double-talk state.

Abstract: A magnetic transfer apparatus writing a servo signal by magnetically transferring to a magnetic recording medium, and an optical type inspection apparatus for optically inspecting scratch or foreign matter on the magnetic recording medium wherein a characteristic grease is used for these apparatuses are disclosed. Grease used in the magnetic transfer apparatus or the optical type inspection apparatus generates sulfur type gas in amount less than or equal to 0.5 ppb.

Abstract: A heart therapy device includes a heart rate detector unit for detecting a heart rate, an evaluation and control unit adaptable to evaluate a measured heart rate and output a therapy control signal, and a therapy unit coupled to the output of the evaluation and control means for realizing at least one therapy having a predetermined therapy. The evaluation and control unit includes a three-area memory for storing heart rate value ranges, a heart rate discriminator for allocating a measured heart rate and outputting a first, second or third discriminator output signal, a stability evaluation unit for outputting a stability output signal and evaluating heart rate stability over a predetermined period of time in response to the output of the second heart rate discriminator output signal, and a logical processing unit for processing the second discriminator output.

Abstract: A broadcast material delivery architecture provides coordinated inclusion of supplemental materials with delivered broadcast material. A broadcaster broadcasts the broadcast materials to a plurality of users, the broadcast material being divided into a plurality of segments. Also broadcast is program data associated with the plurality of segments. A user terminal receives the broadcast material from the broadcaster and retrieving supplemental materials related to said plurality of segments of said broadcast material. To retrieve the supplemental materials, the program data are provided to a data server, which provides parameters for the supplemental materials to the user terminal. The user terminal uses the parameters to retrieve supplemental materials from one or more databases. The user terminal plays the supplemental materials in conjunction with the broadcast material.

Abstract: In general, in one aspect, the invention provides a modular application collaborator for providing inter-operability between applications including a plurality of connectors for communicating with a like plurality of applications and an interchange server. The interchange server includes an application collaboration module and service module. The service module transfers messages between connectors and the application collaboration module. The application collaboration defines the inter-operability between two or more applications. The interchange server service module includes a transaction service and an error service. Transactions are executed in the application collaboration module and the transaction service records each action and a compensating action for undoing an associated action.
