Abstract: A shaft sealing structure includes a V-packing; a first guide bush attached to an inner circumference of the holder; and a scraper arranged at an end of the holder. The V-packing is formed of a thick-walled top portion, a thin-walled inner side skirt portion extending diagonally inward from the top portion, and a thin-walled outer side skirt portion extending diagonally outward from the top portion. The inner side skirt portion slidably contacts an outer surface of the rod at a distal end of the inner side skirt portion, and the outer side skirt portion abuts against an inner surface of the holder at a distal end of the outer side skirt portion. The top portion is sandwiched between the scraper and the first guide bush, and the inner and outer side skirt portions are freely deformable inside a space formed between the first guide bush and the scraper.

More specifically, provided are homogeneous ??T cells excellent in that the ??T cells are not affected by exhaustion of the cells. The foregoing is achieved by ??T cells obtained by subjecting induced pluripotent stem cells (iPS cells) to differentiation induction treatment. Specifically, the foregoing is achieved by ??T cells generated by subjecting iPS cells having a rearranged ??TCR gene (??TCR-type iPS cells) to differentiation induction treatment. According to the method of generating the ??T cell of the present invention, there can be provided ??T cells and a cell population of ??T cells that have an excellent function of having antigen-specific cytotoxic activity in a MHC-unrestricted manner, and that are more homogeneous and have a higher effect than ??T cells separated from peripheral blood.

Abstract: For a non-volatile memory die formed of multiple blocks of memory cells, the memory die has a multi-bit bad block flag for each block stored on the memory die, such as in a fuse ROM. For each block, the multi-bit flag indicates if the block has few defects and is of the highest reliability category, is too defective to be used, or is in of one of multiple recoverability categories. The multi-bit bad blocks values can be determined as part a test process on fresh devices, where the test of a block can be fail stop for critical category errors, but, for recoverable categories, the test continues and tracks the test results to determine a recoverability category for the block and write this onto the die as a bad block flag for each block. These recoverability categories can be incorporated into wear leveling operations.

In case that a user has registered that the user makes a request for a video information distribution service about a specific area to a user management sever in advance, when a mobile phone of the user exists in the specific area, video information is distributed from a video contents server to the mobile phone of the user based on push technology. Alternatively, when traffic of a radio channel connected to the mobile phone carried by the user is lower than a predetermined threshold, video information is distributed from a video contents server to the mobile phone based on push technology.

Abstract: There is realized a self-aligning roller bearing with retainer that stabilizes the orientation of spherical rollers and prevents these spherical rollers from skewing, and which can be rotated at high speed, and furthermore which enables efficient lubricant feed into pockets 9. By rotating a turning tool 14 as it revolves, the surfaces on both sides in the circumferential direction of respective column sections are processed into concave curved surfaces that oppose a rolling surface of the respective spherical rollers across a pocket clearance into which lubricant oil can be fed. The length of the column sections 8c is less than the length in the axial direction of the spherical rollers, and greater than a half of the length, and an end portion of the side surface in the circumferential direction of the respective column sections 8c projects further in the circumferential direction than an intermediate portion thereof, and the spherical rollers are embraced in the pockets 9.

Abstract: In order to ensure high levels of insulation performance, and low cost, and have an excellent external appearance, as a ceramic constituting an insulating coating 6 being a ceramic coating layer, one with alumina as its main component, and in which the content of titanium oxide is limited to 0.01 to 0.2 percent by weight is used. Moreover, a particle size of ceramic forming the coating layer is 10 to 50 ?m, and average particle size is 15 to 25 ?m. By limiting the content of titanium oxide, the insulating coating 6 can be made thin, and by limiting the particle size the film thickness accuracy can be improved, thus simplifying finishing. Moreover, by mixing of titanium oxide, deterioration of the external appearance after sealing can be prevented. As a result, the above problem is solved.
