Title: Production of magnesium hydroxide
Inventor: OMOTE YUKINORI
IPC: C01F5/22
Filed: 1989-11-27
Abstract: PURPOSE:To obtain Mg(OH)2 having small specific surface area and large crystal diameter in a low cost by filtering Mg(OH)2 having specific surface area larger than a fixed value obtained from reaction of Mg<2+>-containing solution with alkali, dehydrating, adding to aqueous solution of MgCl2 and subjecting to hydrothermal synthesis in a fixed condition. CONSTITUTION:A solution containing Mg<2+> such as bittern, sea water or aqueous solution of MgCl2 is reacted with alkali such as slaked lime or caustic alkali to obtain Mg(OH)2 having >=20m<2>/g specific surface area measured by BET method. Next, said Mg(OH)2 is filtered and dehydrated, then added to >=0.5wt.% aqueous solution of MgCl2. Thus, resultant MgCl2-containing Mg(OH)2 slurry is charged to a pressure-resistant vessel and subjected to hydrothermal synthesis in a condition of >=2.0kg/cm<2> pressure at >=120 deg.C with stirring. As the result, Mg(OH)2 having <=10m<2>/g specific surface area measured by BET method and hexagonal-frismatic crystal is obtained. said Mg(OH)2 has low reactivity and stable state is kept for a long period of time as the effect to other substance coexisting in a case of mixing with resin, etc., is small, therefore, said Mg(OH)2 is able to be effectively utilized as a non-halogen fire retardant filler, etc.

IPC: G01F1/00
Filed: 1987-12-07
Abstract: PURPOSE:To realize a method for calculating the flow velocity in an arbitrary flow passage having a complicated shape by a computer and software, by dividing a region where flow velocity is calculated into element groups and calculating the differentiated value of the physical quantity at an element center-of- gravity position from the value of a lattice intersecting point by the mapping to a local coordinates system. CONSTITUTION:A calculation region is divided into a plurality of elements by a lattice line and the value of the physical quantity such as pressure or velocity at the intersecting point (nodal point) of lattice lines is calculated from the value at the center of gravity of elements surrounding the nodal point. The differentiated value of the physical quantity at the element center-of-gravity position is calculated using the differentiated value in a mapping space and a converting matrix. By the introduction of this method, the flow velocity in a flow passage having an arbitrary shape can be calculated by the combination of a computer and software.

Title: Facsimile equipment
Inventor: KOIZUMI SHIGERU
IPC: H04M1/65
Filed: 1988-12-06
Abstract: PURPOSE:To eliminate the need for using a large capacity memory for deputy reception by utilizing a magnetic tape for automatic answering telephone set so as to implement deputy reception when a call is reached from a facsimile equipment at shortage of recording paper. CONSTITUTION:When a call reaches the facsimile equipment in the automatic answering mode, a network control unit NCU 9 acquires a line and a MODEM section 8 detects a facsimile protocol signal. In the case of the call from a facsimile equipment, when the recording paper is not in shortage, a usual facsimile reception is implemented. If recording paper is in shortage, a magnetic tape recorder 15 records a facsimile identification header to start the recording of a facsimile reception signal (protocol signal and picture signal) and an end signal is recorded on the magnetic tape by the end of reception. After the recording paper is supplemented, the signal is reproduced and demodulated, and then printed out. Thus, the deputy reception at shortage of recording paper is executed with inexpensive device configuration without using an expensive large capacity memory.
