Abstract: A compression encoding method which, when performing data conversion using the fact that when data is converted into frequency components, the human eye is sensitive to components close to low frequency components and insensitive to components close to high frequency components, configures a filter in which importance is placed on DC data and its adjacent filter coefficients, calculates the cost for a conversion block which has undergone conversion and quantization, which is required for the data removal of compression encoding using the filter, determines data targets to be removed using the calculated cost and set reference values, and removes the corresponding data, thereby reducing the amount of data to be compressed and therefore increasing compression efficiency without influencing image quality.

Abstract: Disclosed are structure for inlaying precious metal in and outer peripheral surface of a ring and method for manufacturing a ring inlaid with precious metal in an outer peripheral surface. The ring includes a annular blank obtained by compressing a powdered mixture including 80 to 85 weight percent of tungsten carbide in a mold by means of a hydraulic press, and a precious metal inlaid in an outer peripheral surface of the annular blank after sintering the annular blank. An annular groove is formed at an outer peripheral surface of the annular blank, in which the annular groove is defined by sidewalls, which are inwardly inclined in a downward direction, and a bottom wall. Inclined slots having a gradient identical to that of the inclined sidewalls are formed at both lower edge portions of the annular groove, in which the lower edge potions are defined between the bottom wall and the inclined sidewalls.

Abstract: It is an object of the present invention to provide a protein crystal detection method, protein crystal detection apparatus, and protein crystal detection program with which protein crystals can be efficiently detected at a high reliability. To detect protein crystals with the present invention, an observed image obtained by observing a protein solution during crystallization by the vapor diffusion method is differentiated to give a differentiated image constituted by brightness change information indicating how much brightness has changed. Noise then is eliminated from this differentiated image, after which the differentiated image is binarized at a threshold for extracting a characterizing portion, which gives a binarized image in which the portion exhibiting a large change in brightness is left behind as the characterizing portion. Crystallization is evaluated by determining whether or not there are protein crystals from this characterizing portion of the binarized image.

Abstract: The inventors have found that by changing the outer wall shape of at least disk spacer, the air flow of the relevant inner region is disrupted, causing particulate adhesion to be minimized. The air flow disruption acts to blow more air through the inner region, effectively moving particles away from the inner region rather than retaining these particles. The inventors call disk spacers with outer wall shapes disrupting inner region air flow, screw-type spacers.
