Abstract:
A receiver for a digital modulated signal which receives a multi-carrier modulated signal and demodulates a receiving signal by converting it from a time region into a frequency region by Fourier transform is provided. The receiver comprises a Fourier transformer which performs Fourier transform of the receiving signal and an interference removing circuit which reduces an inter-symbol interference or an inter-carrier interference of the receiving signal. The removing circuit is disposed in a front stage of the Fourier transformer.
Abstract:
In conventional fluorescent lamps and imaging devices using the same, there have been challenges that lighting efficiency should be enhanced and variation in emission colors should be reduced. The present invention has solved these challenges by providing a novel fluorescent lamp. The phosphor layers of the fluorescent lamp is composed of at least two types of phosphors, in which at least the most outer surface is a phosphor layer made of one of the phosphors (the first phosphor); and the rest portion of the phosphor layers, is made of mixed phosphors including a plurality of phosphors having respective emitting colors.

The present invention provides an image display device which can acquire a favorable white balance. In the image display device including a first substrate which has a plurality of electron emitting elements, and a second substrate which is arranged to face the first substrate in an opposed manner and has phosphors of three colors consisting of red, green and blue which emit lights upon excitation thereof by electrons emitted from the electron emitting elements, the phosphors of three colors consisting of red, green and blue which emit the lights upon excitation thereof by the electrons emitted from the electron emitting elements displaying 9300K which is standard white of NTSC, an excitation current density ratio of red, green and blue is set to a value which falls within a range of red:green:blue=95-105:100:95-105.
Abstract:
An information processing apparatus includes the following elements. A generation unit generates a multiplexed video frame having a predetermined screen size. A dividing unit divides input audio data into audio data items each having samples for one frame period of the multiplexed video frame. A multiplexing unit multiplexes audio data items obtained by dividing each stream of input audio data and number-of-samples information representing the number of samples thereof. A processing unit processes audio data items multiplexed in a multiplexed video frame input from an input video port, and outputs from an output video port thereof a multiplexed video frame in which the resulting audio data items and the number-of-samples information thereof are multiplexed. An extraction unit extracts the audio data items multiplexed in the multiplexed video frame output from the processing unit in accordance with the number-of-samples information. A transmission unit outputs the extracted audio data items to outside.
Abstract:
A communication device includes a transmission amplifier supplied with a binary transmission signal is capable of choosing between amplifying the transmission signal and entering a high-impedance state at an output. An antenna is supplied with a transmission signal output from the transmission amplifier. A comparator compares a signal received by the antenna with threshold values to obtain a reception signal, which is supplied to a processing unit. A capacitor is connected between the transmission amplifier and the antenna or between the antenna and the comparator. A control unit allows the transmission amplifier to be in the high-impedance state for a period during which the processing unit receives a reception signal.

A vehicle door handle device includes: an electric part which is received within an internal space formed within a door handle so as to form a gap between the electric part and an inner surface of the door handle; and an elastic member which is fixed to the electric part, and is pressed against the inner surface of the door handle.
Abstract:
An A/D conversion processing circuit includes: a switch sequentially switching over multiple inputs to select each thereof according to input bandwidth of the multiple inputs or fixedly selecting a single input; an A/D converter obtaining a digital signal through sampling on a switch output with a sampling frequency according to a necessary signal bandwidth; an interpolation section performing on each signal from a separation section which separates signals included in an A/D converter output, an interpolation processing according to a sampling timing deviation in the A/D converter, to obtain a signal where the multiple inputs are digitally converted at the same sampling timing; and an output section outputting as-is an output of the A/D converter if a signal of the single input is inputted to the A/D converter from the switch, thereby allowing commonly using a single A/D converter for multiple inputs, restraining increased circuit scale and power consumption.
Abstract:
A display apparatus includes a face plate that constitutes a part of a vacuum envelope, a phosphor layer formed on an inner surface of the face plate, and an electron beam source that emits electron beams to the phosphor layer. The face plate includes a light-emitting glass layer containing a light-emitting substance that emits light when electron beams are projected thereon. By extracting energy of electron beams, which have reached the face plate, as light, it is possible to reduce browning that occurs in the face plate and improve brightness of a display image significantly.
