Title: Production of inorganic board
Inventor: MATSUKAWA ATSUSHI
IPC: C04B16/02
Filed: 1988-08-09
Abstract: PURPOSE:To obtain the title board with mechanical strength comparable to the case with asbestos blending by molding into a shaped form a blend of cement with, as reinforcing fiber, the ground product of a sheet form produced by subjecting a mixed fiber comprising pulp fiber and other organic or inorganic fiber to papermaking process, followed by curing. CONSTITUTION:Firstly, a fiber mixture prepared by homogeneously mixing pulp fiber and other organic or inorganic fiber in water is put to papermaking process into a sheet form, which is then dried and ground. The resultant homogeneous fibrous mixture as a reinforcing fiber is then blended with cement and aggregate to prepare a cement blend. The blend is then molded into a shaped form, which is then cured through conventional processes, thus obtaining the objective inorganic board. In the above-mentioned method, since fibers having characteristics with respective disadvantages mutually compensable can be mixed in high dispersibility, the objective inorganic board will be of increased mechanical strength, also having excellent such strength even with identical fiber or the content thereof to conventional one.

IPC: G06F12/10
Filed: 1983-10-26
Abstract: PURPOSE:To reduce the overhead of address conversion by invalidating selectively only an entry corresponding to a translation look-aside buffer (TLB). CONSTITUTION:In a normal memory access mode, an execution control part 15 performs control and a selector 18 selects an address register 16. A TLB19 is retrieved by a TLBADR in the output information of the register 16, and an entry corresponding to the TLB19 is extracted. When the entire page corresponding to a certain segment in a certain virtual space is invalidated, an address counter 17 is increased by the part 15 until the lower five bits in the output information of the counter 17 are all set at ''1''. Thus the corresponding entries of the TLB19 are successively retrieved, and the presence or absence of a corresponding address conversion pair is checked repetitively. When an entry to be invalidated exists, the corresponding bit is reset.

Abstract: PURPOSE:To provide a document generation device and a typeface change method, by which the typeface (different type) of a regular character in a generated document can easily be changed. CONSTITUTION:When a user inputs a character string from an input device 2, CPU 1 executes KANA (Japanese syllabary)-KANJI (Chinese character) conversion on it and stores it in RAM 4. When the user inputs a printing command from the input device 2, CPU 1 displays a menu screen on a display device 7 for permitting the user to select whether the different type is to be used and which kind of the different type is to be used at the time of using the different type. When the usage of the different type and the kind of the different type to be used are selected, CPU 1 develops a character and a mark in a part of the generated document in RAM 4 by font data corresponding to the designated kind of the different type and transmits them to a printing device 3. Thus, the regular document where the character decoration of emphasis and the like is not executed and a printing document where a standard type and the different type are mixed are outputted from the printing device 3.
