Title: Production of magnesium oxide having high resistance to hydration and high fluidity
Inventor: MIYATA SHIGEO
IPC: C01F5/08
Filed: 1989-02-10
Abstract: PURPOSE:To obtain MgO having strong resistance to hydration and high fluidity useful for improvement of thermal conductivity of resin by synthesizing fine crystalline Mg(OH)2 with high dispersibility from water-soluble Mg salt under specific conditions, spray drying the product, baking it at low temp. and pulverizing under the conditions to prevent crumbling of secondary particles. CONSTITUTION:One equiv. of water-soluble Mg salt (e.g. MgCl2) is mixed with <=0.95 equiv., preferably 0.5-0.90 equiv. of alkali material such as NaOH in a water-base medium at <40 deg.C, preferably <30 deg.C to bring them into reaction. Then the production with the mother liquid is heated at about 50-120 deg.C under the atmospheric or higher presure for about 0.5 - several hours to obtain fine crystalline Mg(OH)2 (the mean diameter of secondary particle: <=2mum, BET specific surface area: 15-60m<2>/g, normal diameter of flake-type crystal: 0.01-0.5mum, thickness: 0.01-0.1mum). These fine crystals are dried in a spray dryer to produce granules of 5-500mum secondary particle size, baked at 1100-1600 deg.C, preferably 1200-1400 deg.C for 0.5 - several hours, and then pulverized into the size of the granules produced by spray drying. Thus, MgO having strong resistance to hydration and high fluidity can be obtained.

Title: Communication equipment for high speed mobile body
Inventor: INOUE TAKESHI
IPC: H04B7/15
Filed: 1987-02-13
Abstract: PURPOSE:To simplify the circuit constitution of a receiver and to attain the inexpensive equipment by shifting in advance a transmission frequency of a transmitter by a frequency corresponding to an estimated Doppler shift of a communication wave. CONSTITUTION:A data inputted from a data input terminal 1 is converted into a radio modulation signal by a modulator 2. On the other hand, Doppler information obtained from an object tracing radar or the like from a Doppler information input terminal 9 is inputted to a frequency shift quantity control circuit 8. The synthesized frequency to be shifted is mixed with a radio modulation signal from the modulator 2 by a mixer 3 and converted into a high frequency signal. The Doppler shift is cancelled in the receiver. Thus, it is possible to process the communication wave from the high speed mobile body with high accuracy while employing the conventional constitution for the receiver.

Title: U-band for conduit tube
Inventor: NAKAGAWA MINORU
IPC: F16B2/08
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To make a grasping force larger against an external force which a conduit tube receives in its longitudinal direction, and to increase its earthquake resistance by causing a band body bent into the U-shape to have a curvature having a tensile spring action in its longitudinal direction. SOLUTION: A band body 2 in the U shape as the whole formed by bending a metallic strip board and a curvature 3 bent at one straight part of the U so that its longitudinal section may be in a doglegged shape are provided, and a biting and fixing means 4 is constituted at the U-shaped arc section. And a conduit tube 51 is fixed to a foundation frame 50 having a C-shapd cross section, by the use of fastening bolts 10 and square nuts 11 with rotation preventing grooves. Consequently, the curvature 3 generates a spring action following a displacement, even if a relative displacement is generated between a foundation frame 50 and a conduit tube 51 by the vibration of an earthquake. Accordingly, the curvature 3 absorbs loosening, and it becomes possible to prevent reduction of the grasping force of a U band l for conduit tubes.

Filed: 1979-03-22
Abstract: PURPOSE: To prevent the disconnection of A1 wiring at contacthole through selective removal of PSG film formed on the end of an oxide film in the formation of a PSG on the oxide film.  
     CONSTITUTION: P (n) -type layers 2, 3 and s are formed on a n(p) -type semiconductor substrate and then, holes are made for an element formation region and a wire diffusion layer. After that, an oxide film 9, and polycrystal Si wiring layers 11 and 12 are made to form regions 6 and 7. A PSG 13 is formed all over the film 9 and then, a contact hole is made thereon. At this point, a mask larger than the hole to be contacted is used so that the PSG on the shoulder of the oxide film is subjected to an etching. In other words, a thick PSG film 13 is selectively removed when formed on the end of the oxide film during the formation of the film. Subsequently, an A1 wiring layer 10 is formed.As a result, with the removal of the thick PSG film formed on the stepped sections of the oxide film prevents the A1 wiring 10 formed thereon from becoming thin. Thus, the disconnection can be checked at the contact section.
