摘要： A control device (211) inputs reliability information on the same data block a plurality of times into a reliability storage memory (202). A reliability generating device (201) generates anew reliability information by performing computation processing based on a stochastic computation by using reliability information generated in the previous cycle that has been saved in the reliability storage memory (202) and reliability information generated in the present cycle, and saves the reliability information generated anew in the reliability storage memory (202) when the decoding is performed by using reliability information on the data block same as that in the previous cycle. A column processing computation device (204) computes a column processing output value by using the reliability information generated anew and saved in the reliability storage memory (202) and a row processing output value.

摘要： In an overfilled optical scanner in which a plurality of light beams are used, a uniform luminous-energy distribution is achieved on a scanning plane to be scanned. The optical scanner includes: a light source 3 for producing a first light beam L1 and a second light beam L2; a polygon mirror; a first image formation optical system for leading the light beams L1 and L2 to a deflecting plane of the polygon mirror and for forming, on the deflecting plane, a line image whose width is greater than the plane width of the deflecting plane; and a second image formation optical system for leading the light beams L1 and L2 from the polygon mirror to the scanning plane of a photosensitive drum and forming an image on the scanning plane. The first image formation optical system is adjusted so that the optical axes A1 and A2 of the first and second light beams L1 and L2 are approximately symmetrical about the optical axis A0 of the first image formation optical system. The powers of the first and second light beams L1 and L2 are thus balanced with each other on the scanning plane.

摘要： An ultrasonic vibration tool is made of a block of substantially rectangular parallelepiped form, and has its one end face formed as an output end face, and has its other end face opposite the output end face formed as an input end face. An ultrasonic oscillator is connected to the input end face for transmitting a longitudinal standing wave to the output end face. Peripheries of the input and output end faces of the block constitute mass portions. Between the mass portions are formed slits at a pitch less than a half of an oscillation wavelength, whereby a plurality of elastic portions are obtained. The mass portion on the input end face side has a protrusion having a height equal to or less than a quarter of the oscillation wavelength, thereby obtaining a mass distribution. Hence, a uniform amplitude distribution is achieved in the output end face.
