Power line communication apparatus, registration status confirmation method, and power line communication system

Abstract: A power line communication apparatus capable of performing power line communications with an other power line communication apparatus, the power line communication apparatus, including an authentication processing part which performs an authentication process using at least either an authentication request signal or an authentication response signal with the other power line communication apparatus via a power line, and a signal transmitting part which transmits a predetermined signal to the other power line communication apparatus so that the other power line communication apparatus indicates that the other power line communication apparatus and the power line communication apparatus are made communicatable to each other by the authentication process.

Plasma processing apparatus for large area ion irradiation

Abstract: A plasma processing apparatus performs various plasma processings of a substrate having a large area in a semiconductor element manufacturing process, by using highly excited plasma generated at a low pressure under the application of RF power and a magnetic field. In this plasma processing apparatus, a gas is introduced into a vacuum chamber to be used as an ion source, RF power is applied to two electrodes having respective surfaces opposite to each other through the gas to thereby generate the plasma in the vacuum chamber, and a magnetic field is applied to the plasma from a magnetic field source arranged at a predetermined position. The intensity of the applied magnetic field is set to be 1.5 times or more the magnetic field intensity which causes electron cyclotron resonance to occur at the frequency f of the applied RF power. Particularly, when the frequency f of the RF power is 13.56 MHz, the magnetic field intensity is selected to be in the range from 25 gausses to 35 gausses.

Device and method for smoothing picture signal, device and method for encoding picture and device and method for decoding picture

Abstract: A great decrease of a step, i.e., block distortion, of such as unnatural, abnormal or artifact brightness and color, on a block boundary, leads to much visual improvement of picture quality. Against a picture that has been encoded and decoded by block, the smoothing filter characteristics is changed according to quantizing parameter, block activity of a decoded picture, the activity of each pixel of the decoded picture, and the position with respect to a block boundary of a pixel. A smoothing filter utilizes a weighted mean whose weight is the inverse number of a difference between a target pixel and its surrounding pixels. The weighted mean is obtained by adding a certain number to a weight before taking its inverse number. The value to be added is controlled by the parameter. Similarly, the mixing ratio of a pixel value after performing the smoothing filter and a decoded pixel value is changed depending on the parameter. A filter having strong edge preserving property is utilized for the inside of a block, and a filter having weak edge preserving property is utilized for a block boundary. A filter having edge preserving property is utilized for the post/loop filter.

Multicarrier communication apparatus and multicarrier communication method

Abstract: A multicarrier communication apparatus and the like wherein the arithmetic amount required for calculating a reception weight by which a multicarrier signal is to be multiplied is suppressed, while the reception characteristic for the multicarrier signal is improved. In the apparatus, a subcarrier transmission weight generating part (513) generates a transmission weight of each subcarrier, based on propagation path information of each subcarrier received from a propagation path information generating part (511) and a reception weight of each subcarrier group received from a subcarrier group reception weight generating part (512). The subcarrier transmission weight generating part (513) inputs the generated transmission weights of the respective subcarriers to the corresponding ones of multipliers (522).

Client-server voice customization

Abstract: A user customizes a synthesized voice in a distributed speech synthesis system The user selects voice criteria at a local device (14) The voice criteria represents characteristics that the user desires for a synthesized voice (22) The voice criteria is communicated to a network device (16) The network device generates a set of synthesized voice rules based on the voice criteria (20) The synthesized voice rules represent prosodic aspects and other characteristics of the synthesized voice (20) The synthesized voice rules are communicated to the local device and used to create the synthesized voice (22)
