Title: Production of ultrafine powder of titanium diboride
Inventor: NISHIYAMA KATSUHIRO
IPC: C01B35/04
Filed: 1984-05-07
Abstract: PURPOSE:Powders of Mg and MgO are added to powders of TiO2 and B2O3 and the reaction mixture is treated to collect only TiB2 powder whereby superfine particles of TiB2 are obtained in a median particle size of less than 1mu. CONSTITUTION:Powders of TiO2 and B2O3 are mixed with powders of Mg and MgO and they are mixed in a ball mills for 30min-5hr. Then, the mixture is heated at 650-1,000 deg.C in an argon atmosphere to effect reaction. The reaction mixture is boiled in an aqueous solution of ammonium chloride, distilled water is added, the mixture is centrifuged to remove the supernatant. Then, aqueous hydrogen chloride is added, the mixture is boiled by heating, distilled water is added, the mixture is centrifuged to collect only TiB2 powder, which is dried to give superfine particles of TiB2. The addition of MgO, besides TiO2, B2O3 and Mg, inhibits the explosive reduction reaction, resultantly, the reaction temperature is lowered below 1,000 deg.C, thus the particles of TiB2 are kept superfine.

Title: Composite laminated sheet and base material used therein
Inventor: KAWAGUCHI YUTAKA
IPC: H05K1/03
Filed: 1989-04-07
Abstract: PURPOSE:To lower drying cost and to reduce inferiority due to distruction during process movement by providing a glass nonwoven fabric wherein pigment is contained in a binder at least to the second layer of a glass base material constituting a composite laminated sheet. CONSTITUTION:When a colored glass nonwoven fabric is used in the second layer in addition to or in place of colored glass cloth, dark colored glass cloth becomes unnecessary. The glass nonwoven fabric is prepared by dispersing glass fibers chopped shortly in water and forming the resulting dispersion into a sheet by a papermaking machine and dehydrating said sheet to apply an adhesive thereto in a sizing process before drying. At this time, the glass fibers are cut so that a fiber diameter is 3-13mum, pref., 7-10mum and a fiber length is 3-70mm, pref., 6-20mm before use. These fibers are dispersed in water in an amount of 0.01-0.1wt.% along with a dispersant to prepare an aqueous dispersion which is, in turn, sent to a papermaking process. In the papermaking process, a glass fiber layer containing water in an amount of 10 times the glass fibers is accumulated on a conveyor in a sheet form.

IPC: H02P29/00
Filed: 1986-04-19
Abstract: PURPOSE:To enable performing a speed control and other controls by a common use of one microcomputer by measuring a period of speed-detecting pulse signal on the basis of a divided pulse obtained by frequency-dividing the speed-detecting pulse signal and by taking in results of said measurement. CONSTITUTION:A flip-flop 2 outputs a 1/2 FG signal with a period twice as long as that of a speed-detecting pulse signal(EG signal). While the 1/2 FG signal is at a high level, a gate means 6 is turned ON and a timer counter 4 counts a reference clock signal. If the level of the 1/2 FG signal becomes low, the gate means 6 is turned OFF and an interrupt pulse is outputted from an interrupt command generation circuit 9 after a given delay time. A processing part 7 takes in a counted value of the counter 4 if the interrupt pulse is inputted thereto, and further forms a speed control signal and outputs it to a motor- driving circuit.
