Title: Identification mark, mark identifying method, and mark identifying apparatus
Inventor: YASUDA SHIGERU
IPC: G09F3/02
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To provide an identification mark hard to be forged and a mark identifying apparatus for identifying the identification mark. SOLUTION: A birefringent film 46 is formed on an identification mark 7. When linearly polarized light rays which pass through a polarization filter 33 are radiated to the identification mark 7, the light rays are reflected by the identification mark 7 and after passing through the polarization filter 33, the light rays enter eyes of an observer. In the case of a forged identification mark having no birefringent film on the surface, since the polarization direction of the linearly polarized light rays is not changed at the time when the light rays are reflected by the identification mark, the mark is seen relatively bright even being observed through the polarization filter 33.  On the other hand, in the case of a true identification mark 7 having the birefringent film 46, since the polarization direction is rotated at the time when the polarized light rays pass through the birefringent film 46, the identification mark is seen relatively dark when being observed through the polarization filter 33. Consequently, whether the identification mark is true or forged can easily be judged.

Title: Shield for leakage magnetic field
Inventor: NAKAGAWA TAKAFUMI
IPC: H05H7/14
Filed: 1991-06-25
Abstract: PURPOSE:To prevent the leakage magnetic field from a deflecting electromagnet from entering a vacuum duct by spreading a magnetic putty to shield the leakage magnetic field from the electromagnet, to the vacuum duct of an accelerator. CONSTITUTION:A magnetic putty 6 spread on the peripheral surface of the branch 4 of a vacuum duct 2 increases the thickness of the duct 2 equivalently. As a result, a leakage magnetic field 5 does not enter the duct 2, and the leakage magnetic field 5 from a deflecting electromagnet can be shielded securely. And, by spreading the magnetic putty 6 on the peripheral surface of a nonmagnetic material, after the nonmagnetic material is spread on the peripheral surface of the duct 2, so as to form a double structure, the shielding effect can be improved further. Since a clayish magnetic putty 6 which can be processed easily is used in such a way, the shield can be formed simply even in the place of a complicated structure and the like.

Title: Capillary, capillary working method and gas analyzer using the capillary
Inventor: KOJIMA KENNOSUKE
IPC: G01N1/00
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To prevent various kinds of dust particles from being stuck to the fractured face of a capillary and to prevent the capillary from being clogged, by a method wherein the flow rate of a gas which contains fine particles is adjusted and the tip of the capillary which supplies the gas to a gas analyzer is made smooth. SOLUTION: The fractured surface 4 of a capillary 1 is immersed in an etchant, e.g. a hydrochloric acid solution, housed in a container 2 to make the surface smooth. Then, it is possible to prevent various dust particles from being stuck to the fractured face 4 of the capillary 1. In this case, the fractured face 4 may be made smooth by a lapping operation or a laser beam machining operation in addition to a working operation by the etchent 3. In addition, the capillary 1 is heated by a heater, and it is held at the boiling point or higher of a liquid component in fine particles. Then, it is possible to prevent the fine particles from being stuck due to interaction between the liquid component and the metal surface of the capillary 1. Thereby, it is possible to prevent the capillary 1 from being clogged.  When a fine particle substance emitted from an internal-combustion engine such as, e.g. a diesel engine is measured, a gas analyzer can fulfill a desired function stably for a long time.
