A data receiving device is provided enabling a reduction in the time required for extracting a partial band signal, and capable of being easily made in a simple structure as an LSI device without requiring a plurality of analog circuits having the same characteristics. The data receiving device includes: a first sampler for sampling an in-phase signal I(t) at every predetermined sampling period and outputting the sampled in-phase signal; a second sampler for sampling a quadrature signal at every predetermined sampling period and outputting the sampled quadrature signal; a partial band extracting section structured by a complex filter for extracting partial band signals IBr, QBr from frequency components included in the sampled in-phase signal and the sampled quadrature signal; and first and second delay detection operating sections for performing a delay detecting process based on the partial band signals and outputting detection signals.

The technology which can control a threshold value appropriately, adopting the material which fitted each gate electrode of the MOS structure from which a threshold value differs without making the manufacturing process complicated, and does not make remarkable diffusion to the channel region from the gate electrode is offered. The PMOS transistor has a gate electrode GP, and an N type well which confronts each other via a gate insulating film with this, and the NMOS transistor has a gate electrode GN, and an P type well which confronts each other via a gate insulating film with this. While gate electrode GN includes a polycrystalline silicon layer, gate electrode GP is provided with the laminated structure of a metal layer/polycrystalline silicon layer.

A process for conveniently and efficiently producing a highly pure cinnamaldehyde derivative, for example, (2E)-(3-hydroxy-4-methoxy)cinnamaldehyde, which comprises reacting a benzaldehyde derivative, such as isovanillin and the like, with acetaldehyde in the presence of an alkali, in particular preferably, dropping acetaldehyde little by little thereto in an aqueous solution at a low temperature for the reaction thereof. The cinnamaldehyde derivative thus obtained is selectively reduced to produce 3-(3-hydroxy-4-substituted (with methoxy group or the like)phenyl)propionaldehyde. Further, through a reductive alkylation reaction of the compound thus produced with an aspartame, N-[N-[3-(3-hydroxy-4-substituted (with methoxy group or the like)phenyl)propyl]-L-aspartyl]-L-phenylalanine 1-methyl ester, which is useful as a sweetener having a high sweetening potency, can be industrially and efficiently produced. The processes therefor are also provided.

A semiconductor device includes an interlayer insulation film, an underlying line provided in the interlayer insulation film, a liner film overlying the interlayer insulation film, an interlayer insulation film overlying the liner film. The underlying line has a lower hole and the liner film and the interlayer insulation film have an upper hole communicating with the lower hole, and the lower hole is larger in diameter than the upper hole. The semiconductor device further includes a conductive film provided at an internal wall surface of the lower hole, a barrier metal provided along an internal wall surface of the upper hole, and a Cu film filling the upper and lower holes. The conductive film contains a substance identical to a substance of the barrier metal. A highly reliable semiconductor device can thus be obtained.

摘要:
An apparatus of drawing graphics includes an edge coefficient calculator calculating, from vertex data on vertices of a triangle, edge coefficients of edge functions used to determine whether a pixel is present in an inside region of the triangle, and a bounding box calculator calculating a bounding box of projected images of the triangle on a projection plane based on the edge coefficients. The apparatus also includes a starting point determiner and a traverser. The starting point determiner classifies the projected images of the triangle based on a combination of the edge coefficients for respective sides of the triangle, and determines a scan starting point from a corner of the bounding box based on classification of the projected images. The traverser generates pixel data used in rasterization by scanning the bounding box from the scan starting point.
