PROBLEM TO BE SOLVED: To provide a detection method capable of detecting a sample and the situation of a laminar flow containing the sample simultaneously. SOLUTION: The detection method of a sample conducted through a channel at least performs: the first laminar flow formation process for forming a laminar flow in a state laminated vertically to the wall surface of the channel facing a detection direction by sandwiching a sample flow containing the sample by a sheath flow; the laminar flow bending process for bending the laminar flow so that it is in a laminated state in parallel with the wall surface after the first laminar flow formation process; and the sample detection process for detecting the sample after the laminar flow bending process.

PROBLEM TO BE SOLVED: To provide a flowing method of fine particles capable of achieving high analysis speed and analysis precision, to provide an analysis method using the sending with flowing method, and to provide a substrate for analyzing fine particles in an analysis system of fine particles using microchips. SOLUTION: The method for sending with flowing fine particles is provided, where fine particles are circulated through an arc-shaped peripheral curved channel 2 arranged on a substrate A, and the fine particles are separated in a centrifugal direction according to its specific gravity and flowed from the centrifugal force toward the outside from a curvature center Q of the peripheral curved channel 2. In the sending with flowing method, the fine particles are introduced into the peripheral curved channel 2 as a laminar flow deflected to the side of the curvature center Q, or as a laminar flow laminated in a vertical direction on a substrate surface.

PROBLEM TO BE SOLVED: To provide a method for recovering a minute particle and an apparatus therefor by which a backward flow of the minute particle can be prevented without deteriorating the minute particle when a liquid sending pump is disconnected from a flow passage. SOLUTION: When a liquid comprising minute particles 10a, 10b is made to flow through the flow passage formed on a substrate 1 and the target minute particle 10a is separated and recovered, the minute particle 10a and the minute particle 10b are separated from each other and stored respectively in a recovery liquid storage part 4 and in a waste liquid storage part 5 in a minute particle separation/acquisition part 13 on the basis of the result discriminated by an optical detection part 12. Before the liquid sending pump is disconnected from the flow passage, a part of the flow passage communicated with the recovery fluid storage part 4 is irradiated with a laser beam to deform the flow passage and reduce a diameter of the flow passage.

PROBLEM TO BE SOLVED: To provide an optical measurement method which enables the measurement and dispensation of fine particles correctly. SOLUTION: The method for optically measuring particles passing through a passage includes steps of forming a referential material along at least a part of a wall surface in the passage; and at least detecting optical information from the fine particles or the referential material at a predetermined location in the passage. This method enables the control of various measurement conditions from the optical information as necessary, and then, it can improve measurement precision and shorten a measurement time when the fine particles are analyzed.

PROBLEM TO BE SOLVED: To realize contents reproduction with higher quality without depending upon the storage capacity of a required medium in reproducing contents data of the same materials, for example, in a portable reproducing device that reproduces the required medium storing the contents data. SOLUTION: In a contents reproduction system consisting of the reproducing device for reproducing a medium storing at least contents data, and of a server device connected to the reproducing device through a required network, a storing means of the server device stores contents data of the same materials as those of the contents data stored in the medium. The reproducing device side switches reproduction of contents from the medium and reproduction of contents received from the server device in accordance with a connection state to the server device through the network. If contents data at a reproduction rate higher than that of the contents data stored in the medium are stored in the storing means at this time, contents reproduction with higher quality is realized without depending upon the storage capacity of the medium at the time of the reproduction of contents of the same material.

PROBLEM TO BE SOLVED: To provide a video image providing service which is efficient for both a user and an entrepreneur. SOLUTION: The user carries a user medium 2 around in a facility in a theme park etc. Position data and time data are written into the user medium 2 according to the actions of the user. Photographing is always performed by photographing devices 3α, 3β and 3γ which are installed in each of places in the facility, and photographed video images are stored in a video image producing apparatus 1. When the user wants to be provided with pictures or video images of himself/herself, the user makes the apparatus 1 read the data of the user medium 2 when leaving the facility. The apparatus 1 extracts the video images of the user from the stored video images on the basis of the read data from the user medium, and produces video images to be provided to the user. Then, the produced video images are recorded in a portable recording medium such as a disk, a memory card or a magnetic tape and the recording medium is delivered to the user, or are distributed to the user via a communication line. Thus, the video images are provided. COPYRIGHT: (C)2005,JPO&NCIPI
