Abstract: The present invention provides a method of producing induced pluripotent stem (iPS) cells, comprising bringing a nuclear reprogramming substance into contact with dental pulp stem cells. By using dental pulp stem cells as a source of somatic cells, the efficiency of establishment of human iPS cells by transfer of 3 or 4 factors can be improved dramatically. Additionally, dental pulp stem cells are easily available because they can be isolated and prepared from extracted wisdom teeth and teeth extracted because of periodontal disease and the like, so that they can be used widely as a source of somatic cells for iPS cell banks.

Abstract: A technology for accurately measuring with the use of an ultrasonic flowmeter the flow rate through a nuclear reactor water supply piping interposed between a nuclear reactor and a nuclear reactor water supply pump. In a reactor coolant cleaning system (30), piping to be joined with a reactor water supply system (10) is branched, thereby forming an auxiliary path (A) to be similarly joined with the reactor water supply system (10). The auxiliary path (A) is provided with a restriction part (C) having an inside diameter narrower than that of other parts of the auxiliary path (A) to complete a nuclear reactor water supply piping structure. Through this structure, cavitation bubbles are generated from the restriction part (C). An ultrasonic transducer (40) is disposed between the nuclear reactor (1) and the auxiliary path (A) in the piping for composing the reactor water supply system (10), thereby conducting measurement of the flow rate of fluid within the piping.

Abstract: In an additional writing format optical disk library unit or the like, the processing for automatically reorganizing a volume is carried out effectively so as to intend to reuse media. Whether the number of residual blank media surfaces in a volume is small is judged. If the number is small, media surfaces each having a low data valid rate are extracted from the volume. Valid data on the extracted media surfaces is written and added to a medium surface which is currently set as a writing target, so that data relocation is carried out. Media surfaces occupied only by invalid areas are deregistered from the volume. Further, the media surfaces deregistered from the volume are formatted. The formatted media surfaces are re-registered into the volume.

Abstract: A token and container dispensing device stores containers which can be dispensed to receive a predetermined number of tokens. A user can deposit a certain value and select the appropriate number of tokens. A token dispensing unit can dispense the tokens to a container located at a dispensing section. Both the location of the container and the number of tokens can be monitored and determined to thereby prevent any overflow of tokens. A control unit can automatically control the operation and position an appropriate container to receive a predetermined number of tokens. A second container can also be automatically dispensed if the desired tokens are greater than the storage capacity of the initial container.
