Title: Grain dispersion-type al-base composite material and its production
Inventor: MIURA TSUNEMASA
IPC: C22C1/10
Filed: 1986-09-04
Abstract: PURPOSE:To produce a grain dispersion-type Al-base composite material having high strength and excellent in high-temp. characteristics, by mixing a powder of Al or alloys thereof with reinforced grain and by subjecting the resulting mixture to mechanical alloying, to degasification by heating, to hot compaction and then to hot forming under proper conditions. CONSTITUTION:The powder of Al or alloys thereof is mixed with the reinforced grain, which is formed into a composite powder by mechanical alloying. Subsequently, the above composite powder is heated in a compaction vessel to undergo degasification and is further hot-compacted. Then, hot working such as hot extrusion, etc., is applied to the resulting green compact, so that formed body of composite material can be obtained. In the above process, the stages from mechanical alloying to hot compaction are carried out in a nonoxidizing atmosphere and the additive quantity of an organic seizure inhibitor to be used in mechanical alloying is controlled as much as possible. In this way, the total volume ratio of O to C in the composite material, Vf(O+C), is limited to <=20%. It is preferable that grain reinforcement of <=10mum average grain size is used as the above-mentioned grain reinforcement, and further, the volume ratio of its content, Vf(grain reinforcement), is limited so that it satisfies Vf(O+C)+ Vf(grain reinforcement)<=40%.

Title: Video output device
Inventor: SAKURAI HISAO
IPC: H03F3/45
Filed: 1991-07-25
Abstract: PURPOSE:To incorporate a broad band amplifier means in a video output device outputting a video signal with a high frequency to a picture receiving tube requiring high resolution into an IC. CONSTITUTION:An input video signal Vin is subjected to logarithmic compression via a logarithmic transform means 11 and the result is outputted to a next-stage exponent transform means 12. The transform means 12 applies inverse transform to inputted input video signals Vin1, Vin2 and outputs the result to a driving means to apply the driving control to the picture receiving tube therethrough. Since the input video signal Vin is subjected to logarithmic compression via the logarithmic transform 11 in such a manner, even when an input video signal with a high frequency is inputted for high resolution, too high through-rate is avoided, a broad band pre-driving circuit is far easily built in an IC.
