A method of producing a shell type needle roller bearing having a shell type outer ring whose opposite ends in the axial direction thereof are bent radially inwardly to form flanges; and a plurality of needle rollers arranged along an inner circumferential area of the outer ring. The method comprises the steps of: a) bending one end of the outer ring radially inwardly to form a flange portion on one end of the outer ring for forming the outer ring in the specified shape; b) assembling hardened/tempered needle rollers or un-hardened needle rollers into the outer ring; c) bending other end of the outer ring radially inwardly to form another flange to form a final shape of the needle roller bearing; d) performing a carbonitriding treatment to the assembled needle roller bearing; and then e) performing hardening and tempering treatments to the assembled needle roller bearing.

The present invention relates to an encoding apparatus, an encoding method, an encoding program, a decoding apparatus, a decoding method and a decoding program for adaptively controlling an encoding bit rate. Coefficient data obtained using wavelet transform is quantized, and segmented into bit planes. The coefficient data is entropy encoded from the bit plane of the MSB in a direction from an upper bit position to a lower bit position. Entropy encoding is stopped at a bit position where an amount of code has reached a target amount. On the bit plane, the coefficient data is entropy encoded from a lower frequency region to a higher frequency region. Data greatly affecting subjective image quality of a decoded image is selectively output while the amount of code is easily controlled.

A method of stably producing a toner is provided. This method provides a long-term stabilization of material dispersion in a colorant-dispersed solution and inhibits segregation of the material and provides a more microfine and more uniform dispersion of the colorant in the toner, and moreover produces a toner that has a sharp toner particle diameter distribution. This method of producing toner has at least a colorant dispersion step of obtaining a colorant-dispersed solution by dispersing a pigment-containing colorant in a liquid mixture that contains the colorant and a dissolved resin solution or a polymerizable monomer, wherein the liquid mixture contains a nonionic surfactant and the nonionic surfactant has at least an oxyalkylene group and has a hydrophile-lipophile balance value (HLB value) of 9.0 or more and 17.0 or less.
摘要:
Occurrence of mosquito noise of a macro block that contains even a small plain region is suppressed. One macro block is subdivided into sub blocks each of which is composed of four pixels×four lines. The average value of luminance levels of each sub block is calculated. The absolute values of the difference values between the luminance levels and the average value are obtained for each sub block. The minimum value of the average difference values of the 16 sub blocks of one macro block is selected and decided as an activity of the macro block. Corresponding to the decided activity, a quantizer scale of the macro block is decided. With the decided quantizer scale, the macro block is quantized. According to this method, since the size of each sub block is smaller than the size of a conventional sub block of eight pixels×eight lines, the average difference value of each sub block is more emphasized. Since the minimum value of the average difference values is designated as an activity of the macro block, an activity of a macro block that contains even a small plain portion can be more suppressed. As a result, a quantizer value of a macro block that contains an edge can be decreased. Thus, mosquito noise of a macro block that contains an edge portion of a picture can be suppressed.
