Title: Ink, identification medium prepared by using the same, identification method, and production of identification medium
Inventor: YAMAMOTO YASUMASA
IPC: C09D11/02
Filed: 1993-12-10
Abstract: PURPOSE:To obtain an ink which can give bar codes, etc., capable of being read even if they are hidden and can give an identifying mark on an image of radiography such as X-ray radiography by incorporating a substance having a high capacity of shielding radiations. CONSTITUTION:This ink is produced by using a substance having a high capacity of shielding radiations as the essential component. Examples of the substance include lead and iron for X-rays and gamma-rays and water and paraffins for neutron beams. When the radiation is X-rays and the substance having a high capacity of shielding radiations is lead, the identification medium printed with the ink can be imaged in X-ray radiography. Therefore, this ink is particularly effective in matching an X-ray photograph with the patient. It is desirable from the viewpoint of running cost that paper is used as the recording medium for the identification medium.

IPC: A61B5/352
Filed: 1990-11-19
Abstract: PURPOSE: To eliminate excessive filter treatment by changing the band width of a filter function, which filters an output signal containing an anatomical state component and a noise component of a specimen, according to the noise component. CONSTITUTION: An optical signal receiver 70 receives an optical signal from an optical transmission cable 66 and electric respiratory/heart data formed by superimposing gradient noise signal is outputted in response thereto. A low band-pass filter 72 and a high band-pass filter 74 separate the heart and respiratory signal components.
