Title: Air cleaner, composite air cleaning device using air cleaner and air cleaning method
Inventor: TERAUCHI HIDEAKI
IPC: B01D53/04
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To provide an air cleaner which is easily portable and can be easily taken out for use whenever necessary to prevent a person from inhaling a subcurrent of smoke exhaled by a cigarette smoker, the smoke, microbes or foreign particles adrift through the intermediary of air and make it possible to clean the air in a closed or an isolated space. SOLUTION: A disintegration filter layer and an adsorption layer are fitted as a filter part in a pipe or an air-permeable baglike body and are left as it is housed in such a state that the layers are shielded from an atmosphere. At the same time, the pipe or the baglike body is exposed during using the air cleaner, and the foreign particles or a harmful substance contained in the air are disintegrated, filtered or adsorbed using a forced draft such as air suction or evacuation or a convection generated by natural air circulation. Thus the air cleaning is carried out.

IPC: G10L19/018
Filed: 2000-04-03
Abstract: PROBLEM TO BE SOLVED: To disable the third party to utilize digital contents even when the digital contents is stolen on the sales of the digital contents. SOLUTION: A buyer transmits the buying instruction of music data to a store (step S1-1). His/her own name, etc., is transmitted to the store (step S1-2). Signature data is transmitted to a network store (step S1-3). The store embeds the transmitted signature data into the music data (step S1-4) and transmits the music data to the buyer (step S1-5). The buyer receives this music data (step S1-6) and defroses it (step S1-7). On defrozing it, the signature data is inputted, and only when it is coincident with the embedded signature data, the music data is defrozen and played (step S1-8). Consequently, even when the music data is stolen during transmission, the third party who is not capable of inputting the signature data cannot know the contents of the music data, thereby secure online transaction is realized.
