There is provided a signal processing device and a wireless apparatus capable of not erroneously determining polarity, appropriately performing a spread modulation process, a carrier modulation process, and reception data demodulation process, improving reception accuracy, and miniaturizing a circuit, even when IF carrier frequency shift occurs. The signal processing device and the wireless apparatus includes a spread modulation unit which includes a first differential encoding process section for performing a differential encoding process on a reception data, a differential encoding process section for performing a second differential encoding process on the output, and a spread modulation process section for performing a spread modulation process on the output using a spread code; a carrier modulation unit which quadrature-modulates a transmission data spread modulation signal and a continuous wave; and a reception data decoding unit which performs a correlation process twice and a delay detection process twice.

Provided is a matched filter whose circuit scale can be made significantly smaller by reducing the number of multipliers for a despreading process and the number of adders for an accumulating process. For each in-phase/orthogonal component, the matched filter includes a dual-port RAM that separates written samples into 128 groups each of 32 samples which are collectively read out group by group in order at a speed faster than a write speed in write mode, a bit separating section that separates data read group by group into 32 samples and simultaneously outputs the 32 samples, and 32 despreading/accumulating circuits that, with 16 samples sequentially input from 16 groups being taken as one block, sequentially despread individual samples, accumulate despreading results, and output accumulated values for each block. The matched filter further includes an accumulating section that accumulates absolute values for each block from in-phase/orthogonal outputs of the despreading/accumulating circuits, and outputs correlation value data.

An advertising system is disclosed which is capable of balancing the degree of specifying geographical areas for advertisements and the number of advertisements being displayed, in accordance with content of the advertisements. A database stores the advertisements, after gradually fractionalizing the advertisement areas into increasingly more specific geographic regions, categorizing the advertisements according to levels of fractionalization and the area sections within the levels, and further categorizing the advertisements according to the content thereof. A data receiving means receives from a computer x “perusal data” indicating the levels of fractionalization of the areas, the area sections within the levels and the content of the advertisements. A retrieving means retrieves from the advertisements stored in the database advertisements categorized according to the levels of fractionalization of the areas, the area sections and the content of the advertisements, all of which are concerned with the “perusal data,” and a data transmitting means 4 transmits “advertisement data” of the retrieved advertisements to the computer x.

Compounds represented by formula (I) wherein all symbols represent the same meanings as described in specification and salts thereof. Since the compound represented by the formula (I) binds and antagonizes to DP receptor, it is useful for the prevention or treatment against the disease such as allergic disorder, diseases accompanied with itching, secondary diseases generated by behaviors caused by itching, inflammation, chronic obstructive pulmonary disease, ischemic reperfusion disorder, pleuritis complicated by rheumatoid arthritis, cerebrovascular disease, and ulcerative colitis.
摘要:
A memory device is proposed which enables to guarantee the operation of MRAM elements being magnetically shielded against a large external magnetic fields without being affected by an internal leakage magnetic field. The MRAM elements 30 which are shielded by magnetic shield layers 33, 34 are placed at an intermediate region 41 avoiding an edge region 43 and a center region 42 of the magnetic shield layers 33, 34 so that the MRAM element is secured to operate normally without being affected by the internal leakage magnetic field avoiding the edge region 43 where the magnetic shield effect is reduced by the exterior magnetic field, and avoiding the central region 42 where the internal leakage magnetic field is large

摘要:
A wire is wound in a plurality of core slots 15 on an armature core, and thereby a plurality of coils 18 is formed. In the case.where each coil end portion of the coils is formed in a predetermined shape by a shaping-winding method, a coil end portion of a coil wound in each core slot is formed to be close to an end surface of the armature core 12 as it is directed outside of a radius direction of the shaft 11. In the case where coil end portions are formed by a shaping-winding and direct-winding methods, some of coil end portions are formed between the first winding to the predetermined number-th winding coils by a shaping winding method, and the remaining coil end portions are formed between the predetermined number-th winding and the last winding coils by a direct-winding method.

The compounds of the formula (I) have inhibitory activity of adhesion molecules expression, and are useful for prevention and/or treatment of inflammation, rheumatoid arthritis, allergies, asthma, atopic dermatitis, psoriasis, suppression of ischemia reperfusion injury, nephritis, hepatitis, multiple sclerosis, ulcerative colitis, adult respiratory distress syndrome (ARDS), suppression of transplant rejection, sepsis, diabetes, autoimmune diseases, tumor metastasis, arteriosclerosis and AIDS.
摘要:
A production method of a heterologous protein, comprising culturing a heterologous protein-producing host prepared by gene manipulation in a medium containing a fatty acid or a salt thereof, and a surfactant and harvesting the heterologous protein from the culture. The production amount of the heterologous protein produced by a heterologous protein-producing host can be increased. Moreover, since decomposition of the heterologous protein by an enzyme derived from the host can be inhibited, enabling large scale production of a heterologous protein.
