摘要:
A coefficient sequence of a spreading sequence is sequentially shifted one pitch at a time, transmission data is multiplied by a plurality of coefficient sequences to produce a plurality of transmission data, and the plurality of produced transmission data are added up to produce a transmission data sequence. Alternatively, the coefficient sequence of the spreading sequence is multiplied by the transmission data, the result is sequentially shifted one pitch at a time, and a plurality of transmission data are added up to produce a transmission data sequence. Transmission data is multiplied by the coefficient sequence of a spreading sequence to produce a finite-length signal and this finite-length signal is repeated an infinite number of times to produce an infinite-length signal. Transmission data, which is longer than the coefficient sequence, is cut out from this infinite-length signal to produce a transmission data sequence. This makes it possible to include transmission data into a spreading sequence and, therefore, when the transmission data is modulated through spread spectrum, an increase in the amplitude of a signal is reduced and the dynamic range of an amplifier on the receiving side is reduced.

Namely, preventives and/or remedies for prostatic hypertrophy comprising, as the active ingredient, a compound having antagonism to angiotensin II receptor, a pharmaceutically acceptable salt thereof or a prodrug of the same.
摘要:
In a communication method for transmitting a multipath characteristic measurement signal and a plurality of data transmission signals, the multipath characteristic measurement signal and data transmission signals are a signal array formed by a plurality of coefficient matrices that are orthogonal to one another within the matrices and which comprise at least one coefficient array that is common in the column direction or row direction. The multipath characteristic measurement signal formed by the coefficient matrices is the same signal array formed by the one common coefficient array. As a result, the transmission wait time and the signal reception time required for transmission of a multiplicity of data transmission signals are shortened in the simultaneous transmission of the multipath characteristic measurement signal and the plurality of data transmission signals by the spread modulation of transmission data by means of a spread spectrum, whereby the scale of the reception processing device is miniaturized.

A motor producing a rectilinear drive force can be simultaneously provided with a small size and a light weight, high accuracy and a large drive force. In a spiral linear motor 1, a rotator 3 and stator 2 are both constituted having a spiral shape and, by joining together both spiral-shaped parts, a drive force is produced in the axial direction during rotation in a spiral shape. By affording the spiral linear motor a spiral shape, a large drive force can be obtained similarly to that of a reduction gear and a large drive force can be obtained by utilizing a large area that lies opposite in the axial direction of the rotator and stator.
摘要:
When transmission data is modulated via spread spectrum, not a spreading sequence itself but a transmission data sequence is processed to make the periodic spectrum of a transmission signal a non-correlated spectrum to reduce an increase in the amplitude of the signal and to reduce the dynamic range of an amplifier on a receiving side. A transmission signal production method comprises the steps of multiplying the transmission data by the coefficients of a predetermined coefficient sequence to produce a plurality of transmission data; and adding 0 data of a predetermined length between the plurality of transmission data, produced by multiplying the transmission data by the coefficients, to produce a transmission data sequence.

An ocular fundus portion analyzer and the method are provided for attaining accurate and quick detection and diagnoses of an ocular fundus defect portion, such as an excavation of an optic disk caused by glaucoma and a macula retinae caused by retinal detachment, by dealing with a large number of single-shot ocular fundus images, for example, taken in physical examinations. It is configured to include an image importing portion for importing an image of an ocular fundus portion taken by a visible radiation or a near-infrared radiation; a pixel data generation portion for generating pixel data including pixel positions and luminance of pixels constituting the image; a local plane gradient image generation portion for generating a three-dimensional image from pixel positions and luminance of the pixel data, obtaining a local approximation plane at any pixel and generating a local plane gradient image from a gradient angle with respect to a control plane of the three-dimensional image; and a display portion for displaying the local plane gradient image.

A digital communication device includes: a modulator having encoding means for converting two-dimensional digital information signal into a three-dimensional signal and phase modulation means for modifying the carrier phase in according to the three-dimensional signal; and a demodulator having phase demodulation means for detecting information on the three-dimensional signal from the received phase-modulated wave and demodulation means for deciding the two-dimensional digital information from the information on the three-dimensional signal. The digital communication device has a bit error ratio and an occupied radio band width equivalent to a digital communication device using the conventional QPSK or π/4 shift QPSK and the error correction method and greatly improves the amplitude fluctuation. Moreover, the digital communication device can transmit a signal with a narrower occupied frequency band width while maintaining the same constant envelope characteristic as the GMSK using the conventional error correction code.
