Abstract: There is provided a production method for a resist composition purified product, which includes a step (i) of filtering a resist composition with a filter having a porous structure in which adjacent spherical cells are connected to each other. The filter includes a porous membrane containing at least one resin selected from the group consisting of polyimide and polyamide imide. The resist composition contains a base material component (A) that exhibits changed solubility in a developing solution under action of acid, an onium salt, and an organic solvent component (S), where the content of the organic solvent component (S) is 97% by mass or more.

Abstract: A filtration filter used for filtering a liquid chemical for lithography, provided with a polyimide resin porous membrane; a filtration method including allowing a liquid chemical for lithography to pass through the filtration filter; and a production method of a purified liquid chemical product for lithography, including filtering a liquid chemical for lithography by the filtration method.

Abstract: A ceramic electronic component has a ceramic element assembly, external electrodes, and metal terminals. The external electrodes are arranged on the surface of the ceramic element assembly. The external electrodes contain a sintered metal. The metal terminals are electrically connected to the external electrodes, respectively. The external electrode and the metal terminal are directly diffusion-bonded by diffusion of metal in the metal terminals into the external electrodes. The above arrangement provides a ceramic electronic component having highly reliable metal particle bonding and a method for manufacturing the same.

Abstract: A system for managing an interprocessor common memory in a multiprocessor system includes a memory block pool and a management table. The memory block pool is obtained by chaining N memory blocks of segmented memory blocks in the common memory by using two Queue Control Blocks ("QCBs") respectively assigned to the processors in opposite directions. The management table is constituted by a common memory block total count N required to manage the memory block pool, a memory block count b.sub.X(modN) (where X is 1 or 2) fetched by each of the processors, and a memory block count c.sub.X(modN) (where X is 1 or 2) which can be fetched at once. Each processor has a semaphore function for realizing means for asynchronously fetching e.sub.Y memory blocks from a start of a QCB.sub.
