IPC: H04J11/00
Filed: 2010-10-20
Abstract: PROBLEM TO BE SOLVED: To reduce the scale of a circuit in the case that a result of Fourier transformation and a result of inverse Fourier transformation are required for signal processing.SOLUTION: Fourier transformation is performed by using Fourier transformation data x(n) or inverse Fourier transformation data Y(k), stored in an input memory 93, and a result of the Fourier transformation is stored to an output memory 95. In the case that a Fourier transformation operation flag is H, the data is read in an order of addresses from 0, 1,..., N-1, and, as a result of the Fourier transformation, each data is output as X(0), X(1),..., X(N-1). On the other hand, in the case that the Fourier transformation operation flag is L, the data is read in an order of the addresses from 0, N-1, N-2,..., 2, 1, and, as a result of the inverse Fourier transformation, each data is output as y(0), y(1),..., y(N-1). The present invention can be applied to a receiving apparatus capable of multicarrier transmission.

Inventor: OKITA KUNIO
IPC: H04M3/56
Filed: 2010-10-27
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a repeating device to be used is narrowed down under an assumption that the use of the repeating device of an IP address close to an IP address of a terminal such as a video conference terminal allows transmission/reception of image data of high picture quality and voice data of high sound quality, conventionally, and therefore, the assumption may not be right depending upon the environment of a network.SOLUTION: By selecting repeating devices to which two or more higher-order IP addresses close to an IP address of a transmission terminal are respectively allocated, two or more candidates of the repeating devices to be finally used can be left. Therefore, by actually transmitting/receiving previous transmission information between transmission terminals through the respective repeating devices as the candidates subsequently, the repeating devices are narrowed down, out of the two or more repeating device candidates, to the repeating device that relayed prescribed information with a shortest required time for the transmission/reception. Thus, communication using image data with high quality or the like can be implemented under a real network environment.

Title: Musical sound generation apparatus and program
Inventor: HAGINO KIYOSHI
IPC: G10H1/18
Filed: 2010-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a musical sound generation apparatus which is capable of continuously generating musical sounds of the same pitch in response to an identical-sound continuous keying operation while effectively utilizing sounding channels restricted in number.SOLUTION: A stationary sound and a non-stationary sound are enabled to be generated by different sounding channels independently. Regarding the allocation of a sounding channel for musical sound generation in identical-sound continuous keying operation, for the non-stationary sound, musical sound generation is performed by newly allocating a sounding channel each time musical sound generation information is acquired. For the stationary sound, on the other hand, musical sound generation is performed by continuously allocating a sounding channel which is first allocated in the identical-sound continuous keying operation, without newly allocating any sounding channel each time musical sound generation information is acquired. Thus, only the non-stationary sound can be generated independently in accordance with the acquisition of the musical sound generation information in the state where the stationary sounds are continuously generated, thereby generating musical sounds while effectively utilizing sounding channels without occupying a number of sounding channels for a long time.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a vibration-proof rubber fitting which can significantly reduce COgenerated in a hot water washing step and can also reduce use energy, thereby capable of reducing energy cost.SOLUTION: The vibration-proof rubber fitting is produced by successively performing the steps of: pretreatment, chemical conversion coating treatment, washing, hot water washing, and drying. In the hot water washing step, hot water supplied from a heat pump supply part 38 is allowed to flow into a buffer tank 54, and at the same time, hot water in the buffer tank 54 is allowed to continuously flow out to be continuously supplied to a hot water washing tank 34 at a set flow rate, while discharging hot water in the hot water washing tank 34 by overflowing.
