摘要:
Light irradiates one light incident position on the surface of a scattering-absorption body. The light that propagates through the interior of the scattering-absorption body is detected at one light detecting position on the surface of the scattering-absorption body. On the basis of a light detection signal, a temporal profile of the light intensity of the detected light is acquired, and on the basis of the temporal profile, an mean optical path length of the light in the interior of the scattering-absorption body and information relating to the amount of substance to be measured in a region to be measured are calculated. The information relating to the amount of substance to be measured is corrected on the basis of the mean optical path length, such that the longer the mean optical path length, the greater the amount of substance to be measured is.

A bill discriminating and counting apparatus in which a plurality of bills with different sizes are filled between side hopper members and fed into a transport path by a feeding mechanism. The feeding mechanism comprises a plurality of rollers disposed in a bilaterally symmetrical state. The plurality of rollers are arranged so that, when a distance between the side hopper members is adjusted according to the longitudinal dimension of a bill with the maximum dimension in the longitudinal direction and a bill with the minimum dimension in the longitudinal direction is disposed at a position where the bill is brought into contact with one of the side hopper members, at least a part of the rollers installed on the opposite side of the side hopper member where the bill is brought into contact therewith is brought into contact with the bill. Also, the feeding mechanism comprises a guide member guiding the bill to the inlet of the transport path. The guide member comprises a guide surfaces formed so that the opening area thereof is gradually increased toward the both ends thereof, and the guide surfaces are formed so that the opening area thereof is converged to zero from the insert port toward the inlet of the transport path.

A gas sensor comprising a first measuring chamber for introducing a gas to be measured, a second measuring chamber for detection of the gas to be measured, and as pump cells a first pump cell having a pair of pump electrodes, and a second pump cell having a measuring electrode and an auxiliary pump electrode, wherein a porous alumina sintered body having communicating pores of 500-1100 Å in average pore diameter and 6-16% in porosity is formed as an electrode protective layer on the surface of at least the measuring electrode of the second pump cell in such a manner that the alumina sintered body covers the measuring electrode. The gas sensor can be use for long period of time because of the protective layer.

摘要:
In a data decompressor, a variable length decoding unit extracts a variable length code from compressed image data, performs variable length decoding of the extracted variable length code, and restores quantized data before the variable length encoding was applied. An inverse quantization unit performs inverse quantization on the restored quantized data to generate orthogonal transform coefficients of each block and writes the generated orthogonal transform coefficients to a memory. An inverse orthogonal transform unit reads the orthogonal transform coefficients of each block from the memory and performs an inverse transform of the orthogonal transform performed by a data compressor on the orthogonal transform coefficients to thereby restore an image of each block. The inverse orthogonal transform unit is constructed so as to perform the inverse transform of the orthogonal transform coefficients in parallel with the variable length decoding of the variable length decoding unit and the inverse quantization of the inverse quantization unit.
