Title: Particle group for inspecting air filter and method for inspecting air filter
Inventor: HARA SATOSHI
IPC: G01N1/00
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To ease a problem being generated due to the diffusion to the downstream side when a filter is used and to improve the stability and reproducibility by making a particle group include a plurality of aggregate particles that are composed of a plurality of solid primary particles whose average particle diameter is less than a specific value. SOLUTION: The average particle diameter or the particle diameter of a primary particle is preferably 55 nm, is further preferably 20 nm or less, and is especially preferably 10 nm or less. The lower limit of the particle diameter is not limited especially as far as an inspection cannot be affected. The range of the particle diameter of the aggregate particle to be included in the particle group to be formed should be selected according to the performance of a filter to be inspected. However, a high- performance filter is to be inspected, the range is normally equal to or more than 0.05 μm and is especially preferably 0.055 to 0.5 μm. In the aggregate particle, the quality of the material of the aggregate particle that is made of the primary particle of the solid is essentially identical to that of the primary particle of the solid.  In this manner, by using the primary particle, problems caused by the particle group of liquid can be solved. Both organic and inorganic primary particles can be used as far as they are non-volatile, solid, has improved dispersion property, and are less than 55 nm.

Title: Photographing method for photographic paper film
Inventor: KASHIKO MASAHARU
IPC: B41M5/00
Filed: 1985-05-27
Abstract: PURPOSE:To obtain an image with high durability without using a camera, by a method wherein the shape or pattern of an object to be photographed is transferred as a toner image onto a photographic paper film coated with a gelatinous layer by dry-type copying, followed by exposure and development. CONSTITUTION:The photographic paper film is processed as a copying paper by a dry-type copying machine. Onto the gelatinous layer 12 applied to a base 11, the image of the object to be photographed is transferred as a toner image formed of a toner 13. The paper film thus treated is subjected to a fixing treatment using an ordinary photographic fixing liquid, whereby a silver salt is dissolved away from the gelatinous layer 12 at parts other than the part coated with the toner 13. After washing with water, the toner 13 is released by a solvent such as a thinner or an adhesive tape. The part from which the toner 13 has been released has not been desilvering. Then, printing is conducted, whereby the part corresponding to the transferred image is turned black, resulting in obtaining a black positive film.
