摘要:
When machining of a circumferential groove is performed by advancing a cutting tool which is attached to a rotating shaft extending to an inner side from an outer side of a rotating work into the work in a depth direction, the rotating shaft is downwardly inclined toward the inner side of the work at a predetermined inclination angle, a trajectory of a cutting edge within the work is arranged to be an ellipse of which minor axis is oriented in the radial direction connecting a deepest point thereof and the center of the work as viewing in a plane view, and the work is cut as lowering the cutting tool until reaching groove depth of a machining target while maintaining the inclination angle, so that deviation occurring in a direction of an axis toward a work center axis in parallel to a work face from a point on the work face on which the deepest point is projected or an axis of the rotating shaft of the cutting tool projected on the work face can be arbitrarily set.

The present invention relates to a signal processing apparatus and a signal processing method, an encoder and an encoding method, a decoder and a decoding method, and a program capable of reproducing music signal having a better sound quality by expansion of frequency band.A sampling frequency conversion unit converts a sampling frequency of an input signal, and a sub-band division circuit divides the input signal after the sampling conversion into sub-band signals of sub-bands having the number corresponding to the sampling frequency.A pseudo high band sub-band power calculation circuit calculates pseudo high band sub-band powers based on low band signals of the input signal and coefficient tables having coefficients for the respective high band sub-bands. A pseudo high band sub-band power difference calculation circuit compares high band sub-band powers and the pseudo high band sub-band powers to each other and selects a coefficient table from plural coefficient tables. In addition, a coefficient index which specifies the coefficient table is encoded and set as high band encoded data. The present invention can be applied to an encoder.

The present invention relates to a frequency band extending device and method, an encoding device and method, a decoding device and method, and a program, whereby music signals can be played with higher sound quality due to the extension of frequency bands.A bandpass filter 13 divides an input signal into multiple sub-band signals, a feature amount calculating circuit 14 calculates feature amount using at least one of the multiple divided sub-band signals and the input signal, a high frequency sub-band power estimating circuit 15 calculates an estimated value of a high frequency sub-band power based on the calculated feature amount, a high frequency signal generating circuit 16 generates a high frequency signal component based on the multiple sub-band signals divided by the bandpass filter 13, and the estimated value of the high frequency sub-band power calculated by the high frequency sub-band power estimating circuit 15. A frequency band extending device 10 extends the frequency band of the input signal using a high frequency signal component. The present invention may be applied to a frequency band extending device, for example.

In a presence system in which one user users a plurality of terminals, dynamically changing buddy lists are synchronized between the terminals. A presence notification message is sent to all the terminals of the user. The timing of sending includes, for example, when the presence information of a buddy is updated, when a new buddy is set, when display attribute information is updated, when a buddy is cancelled, and when a presence notification of unknown presentity is made. Thus, when one user uses a plurality of terminals in the presence system, dynamically changing buddy lists can be synchronized between the terminals. In addition, the display formats of the buddy lists do not differ from one terminal to another, and the same display format is attained.

The present invention relates to a control device, a control method, and a program capable of improving operability with a simpler configuration.A reproducing apparatus 11 which reproduces sound such as music includes earphones 21 which are worn by a user on the ears and a body 22. A sound pickup unit 31 collects sounds around the reproducing apparatus 11, and a determination unit 34 extracts future amounts from the collected sound and determines whether the sound corresponds to an operation sound generated when the sound pickup unit 31 is directly tapped by the user. A controller 35 executes a process in accordance with a result of the determination performed by the determination unit 34. For example, when a sound pickup unit 31-1 is tapped once within a predetermined period of time, the controller 35 instructs a reproduction controller 39 to stop reproduction of music. In the reproducing apparatus 11, various function control processes may be performed by a simple operation of tapping the sound pickup unit 31 and buttons are not required. The present invention is applicable to a music player.
