We measured the transmittance of filters and the substitutes for direct observation of the sun, from 2009 to 2012. In this paper, we report the results of the measurements in detail. This paper gives fundamental data for observing solar eclipses safely.

May 21, 2012, solar eclipse was observed in Japan. This time, annular eclipse occurred over a wide range; i.e. the southern part of Kyushu, the southern part of Shikoku, the southern part of the Kinki, the southern part of the Chubu, such as the Kanto. Other regions became a partial solar eclipse. Approximately 83 million people are living in the path of annular phase, we were expected many people to observe the eclipse. Eclipse is a valuable opportunity to increase interest in science. On the other hand, when observing the sun, it runs a strong risk that leads to trouble in the eyes of people due to the strong sunlight. For example, in the case of the eclipse in Germany in 1912, solar eclipse retinopathy patients of 3,500 has occurred. We conducted our activities for many people to observe the eclipse safe. One of them is the spread of safe solar eclipse observation method, another is a research study of the safety of the solar eclipse glasses.In this paper, we report the transmittance measured in the various filters; solar viewing glass on the market, and their substitutes. These are valuable archival material related to solar observation glass for the solar eclipse in the future.

For decreasing particulate matter in sterile products, it is important to find the cause of the particulate contamination by containers as well as drugs. Particulate matter in laminated aluminum film, which is one of the multiple materials to be useful for the container of drugs, was investigated by various methods. It was found that the number of particles in the water increased with time by the particle counter when water was filled in a bag of laminated aluminum film. The number of the generated particles from the bag left for several hours exceeded that of the bag shaken sixty times. Besides, many white particles were detected under the microscope by filtrating water. The white particles weren't observed from the polyethylene film alone before lamination. And white particles was observed irrespective of treatment of heat-seal. Therefore, it was supposed lamination process was the cause of the particle formation. The number of particles in heat-sealed bag increased about twice as many as the number of particles in non-heat-seal bag (sealed by adhesive tape). Therefore, the treatment of heat-seal was also cause of the particle formation. In either case, film was held under high temperature and high pressure. Moreover, analyses of white particles showed that main ingredient in particles was same with an ingredient in polyethylene film which was soluble in ethanol. Therefore, it was presumed that the condition of high temperature and pressure caused the particle formation from an impurity in polyethylene, and particles appeared in water.
