Title: Antimicrobial composition and its production
Inventor: OSANAI HIDEYO
IPC: A01N59/16
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To provide antimicrobial particles excellent in stably sustaining an antimicrobial power and therefore highly atoxic, and capable of preventing resins, etc., from degrading brightness and discoloring even in kneaded in the resins, by strengthening supportability for antimicrobial metals (e.g. silver) on inorganic particles. SOLUTION: This antimicrobial composition is obtained by overgrinding inorganic particles (e.g. calcium carbonate) along with antimicrobial metallic particles (e.g. silver particles) through dry blending and grinding under the application of pressure, based on mechanochemical effects, to form compound antimicrobial particles having an amorphous structure and combined by covalent bonds and is also prepared by adding 0.5-3 wt.% of the compound antimicrobial particles to a resin. It is possible to form the compound antimicrobial particles having a particle diameter of 0.01-10 μm by blending at least one kind of inorganic particles (having a particle diameter of 1-50 μm) selected from a group composed of calcium carbonate, barium sulfate and zirconium hydroxide with antimicrobial metallic particles composed of at least one king selected from a group composed of silver, copper and zinc and by subjecting them to overgrinding.

Filed: 1980-04-30
Abstract: PURPOSE: To facilitate the retrieval for Chinese characters by classifying all the contained characters into optimum small blocks based on the analysis of the retrieval operation for characters in the character tray of an input device for the Chinese characters.  
     CONSTITUTION: When a time required for retrieving desired characters from the Chinese characters tray wherein a number of Chinese characters are contained is counted based on the analysis of the operation of retrieval thereof, it becomes the minimum in the case when all the contained characters are classified into blocks for n units of characters. On the occasion, the value of n turns to be 8 when the kind of representative reading is expressed as G and all numbers of characters arranged according to the representative reading as N and when counting is made based on the values of N=2965 and G=50, which are the integers nearest to the values obtained from the formula. Based on the above counting, a minor group "ko-u" in a major group "ko" on the character tray, for instance, is further classified into blocks each of which consists of about 8 units of characters in accordance with a radical or the similarity of the component of the character and thus the retrieval  for the characters is facilitated.

Abstract: PURPOSE:To get rid of stain in a lifting up/down passage caused by lubricating oil and suppress floating vertical vibration by bringing members for giving slide resistance into contact with the sides of a front side guide roller or a tumble preventing guide roller and holding these members on a cage. CONSTITUTION:A front side guide roller 12 and a tumble preventing guide roller 10 are brought into contact with the end face 6a and the side face 6b of a guide rail 6 respectively, and s slide resistance is given to the tumble preventing guide roller 10 by means of shoes 15, 15 held by a cage. As a result, because of the disuse of guide shoes which slide on a guide rail, no lubricating oil is fed to the sliding portion and the cage can be lifted up/down along the guide rail 6 without being tumbled, enabling sufficiently large slide resistance to be given to the tumble preventing guide roller 10 by means of the shoes 15, 15. Hence the stain, in a lifting up/down passage caused by lubricating oil can be eliminated while sufficiently suppressing the floating vertical vibration of the cage.
