Abstract: An IC chip 10 is divided into the analog circuit area 1 and a digital circuit area 2 in its layout. A clock generator circuit 6 that generates a clock signal CK is arranged within the digital circuit area 2, and a switching circuit 4 that performs switching operations by the clock signal CK is also arranged within the digital circuit area 2. This enables shortening of the wiring length of the clock line 9, which is routed from the clock generator circuit 6 to the switching circuit 4, and also enables the distance between the clock line 9 and the analog circuits within the analog circuit area 1 to be as great as possible. Through this, inconvenience where digital noise caused by the clock signal flowing through the clock line 9 jumps into analog circuits can be suppressed.

Abstract: In a semiconductor device in which a source/drain and a wiring layer are connected to each other through an associated buried conductive layer, a separation width of the buried conductive layer on a upper portion of a gate electrode is made small in order to manufacture a highly reliable and fine MOS transistor. After a silicon oxide film has been formed on a first polycrystalline silicon film so as to be aligned with a width of a gate electrode, a second polycrystalline silicon film formed on the whole surface of a substrate is selectively etched away so as to be left only on both side faces of a pattern of the silicon oxide film. Thereafter, the first polycrystalline silicon film is separated with a width which is smaller than that of the gate electrode by a width of a pattern of the second polycrystalline silicon film. In such a way, the buried conductive layer including the first and second polycrystalline silicon films is formed.

Abstract: On a compression side, from an inputted analog signal 101, points 102a to 102f where a differential absolute value is at a predetermined value or smaller are detected as sample points, and a pair of discrete amplitude data on the sample points and timing data indicative of a time interval between sample points is obtained as compressed data. On an expansion side, amplitude data and timing data that are included in the compressed data are used to obtain expansion data by determining interpolation data for interpolating two pieces of amplitude data, based on the two pieces of amplitude data on two successive sample points and timing data therebetween. Thus, when a signal on a time base is compressed and expanded, the operation can be performed on a time base without frequency conversion.

Abstract: An apparatus and method capable of providing IR spectral information using IR absorption phenomena requires no moving parts or Fourier Transform during operation. IR spectral information and chemical analysis of a sample in a sample containing functional groups is determined by using an IR source, a sampling accessory for positioning the sample volume, an optically dispersive element, a focal plane array (FPA) arranged to detect the dispersed light beam, and a processor and display to control the FPA, and display an IR spectrograph. Fiber-optic coupling allows remote sensing, and portability, reliability, and ruggedness is enhanced due to the no-moving part construction. Use of the apparatus and method has broad industrial and environmental application, including measurement of thickness and chemical composition of various films, coatings, and liquids, and may also be used in real-time sensing of hazardous materials, including chemical and biological warfare agents.

If this sorting processing is applied to compression processing having a characteristic that a compression ratio is not increased in a high-frequency region, it becomes possible to improve a compression ratio without damaging a quality of reproduced data by decompression at all.
