    摘要: A region of an Si layer 15 located between source and drain regions 19 and 20 is an Si body region 21 which contains an n-type impurity of high concentration. An Si layer 16 and an SiGe layer 17 are, in an as grown state, undoped layers into which no n-type impurity is doped. Regions of the Si layer 16 and the SiGe layer 17 located between the source and drain regions 19 and 20 are an Si buffer region 22 and an SiGe channel region 23, respectively, which contain the n-type impurity of low concentration. A region of an Si film 18 located directly under a gate insulating film 12 is an Si cap region 24 into which a p-type impurity (5×1017 atoms·cm−3) is doped. Accordingly, a semiconductor device in which an increase in threshold voltage is suppressed can be achieved.

    摘要: Amplitude, phase and frequency of a sine wave to be generated are calculated on the basis of feature quantity s1 delivered to feature quantity detecting means (2), and are sent to initialization means (3). The initialization means (3) calculates first two points of the sine wave to send the points thus calculated to oscillator (sine wave generating means) (4) as initial value s4. The oscillator (4) sequentially calculates values of respective sample points of waveform by using recurrence formula in accordance with initial value or values instructed from the initialization means (3) to thereby generate a sine wave signal. Thus, sine wave generation is performed without performing modulo-addressing.

    摘要: To simplify a manufacturing process of a transverse electric field mode liquid crystal display device by using a non-linear resistance element such as a TFD (Thin Film Diode) as a switching element. In a liquid crystal display device having a pair of substrates with liquid crystal interposed therebetween, one of the substrates consists of an electrode substrate. On the electrode substrate, there are provided a first group of electrodes, a second group of electrodes crossing the first group of electrodes with an insulating layer interposed therebetween, non-linear resistance elements, one end of each of the non-linear resistance elements being connected to the respective one of the second group of electrodes, and pixel electrodes opposing the first group of electrodes, each pixel electrode being connected to the other end of each of the non-linear resistance elements. Since the non-linear resistance elements have a so-called TFD (MIM) structure made of metal-insulating layer-metal, the manufacturing process is simple. Therefore, it is possible to manufacture the transverse electric field mode display device at low cost.

    摘要: The present invention relates to an optical waveguide type grating element and others in structure for decreasing absolute values of chromatic dispersion occurring in selective reflection of each of signal channels in a reflection band. The optical waveguide type grating element is provided with an optical waveguide in which signal light containing a plurality of signal channels spaced at a channel spacing λi propagates, and a grating which is an index modulation formed over a predetermined range of the optical waveguide. Particularly, the optical waveguide type grating element has a transmittance of −20 dB or less for each of the signal channels in the reflection band, and has a reflectance of −20 dB or less for each of signal channels outside the reflection band. Furthermore, a deviation of a group delay time of each of the signal channels in the reflection band, which is caused by reflection in the grating, is 10 ps or less in a wavelength range of (λCH−λi×0.375/2) or more but (λCH+λi×0.375/2) or less, where λCH is a center wavelength of each signal channel.

    摘要: The purpose of this invention is to provide a printer apparatus capable of receiving concurrent input print data from plural input ports without increasing receiving buffer memory and image creator. A controller determines whether an image creator is used by other jobs when starting receiving print data through any one of the plural input ports. When not used, print data related to the current job is stored in a receiving buffer memory and at the same time create print data stored in the buffer memory via the image creator. On the other hand, when other jobs use the image creator, the print data related to the current job is stored in a hard disk unit and then is created the print data stored in the hard disk unit when the image creating device becomes available.
