Title: Manufacture of al matrix composite
Inventor: MORITAKA MITSURU
IPC: C22C47/14
Filed: 1988-06-23
Abstract: PURPOSE:To manufacture Al matrix composite having uniform quality and excellent strength and hardness by drying and hardening a formed body composing of Al alloy powder obtd. through organic binder and reinforcing material at suitable temp. and sintering under pressurizing at the specific temp. after compacting. CONSTITUTION:The Al alloy powder containing one or more kinds among active precipitation strengthening elements of Mg, Li, Zn, etc., and the reinforcing material of about 5-40vol.% of whisker, short fiber or granular state of SiC, Al2O3, etc., are uniformly dispersed in liquid dispersing medium containing the organic binder. The obtd. mixed slurry is poured into a forming die having slit, fine holes, etc., to be possible to discharge only liquid material and pressurized at about 300-600kg/cm<2>. By this method, the liquid in the mixed slurry is removed to obtain the green compact shaped through the binder uniformly containing the reinforcing material. Successively, this green compact is dried and hardened at the temp. range between >=b.p. of the dispersing medium and <=400 deg.C. This hardened compact is compressed at <=400 deg.C to make >=about 55% packing ratio. This high packing formed body is sintered under pressurizing at solid phase range or solid-liquid coexistent temp. of 400-660 deg.C.

IPC: C01B13/34
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for synthesizing a powder capable of sustaining combustion without accumulating a synthesized powder on an opening for jetting an emulsion. SOLUTION: This apparatus for synthesizing a powder is equipped with an emulsion nozzle 3 for jetting an emulsion and a combustion supporting gas nozzle 4 for jetting a combustion supporting gas arranged side by side with the emulsion nozzle 3 and a jetting end opening 31 of the emulsion nozzle 3 is protruded from a jetting end opening 41 of the combustion supporting gas nozzle 4. Since the emulsion jetting end is protruded from the combustion supporting gas jetting end in the jetting direction, the jetting end opening 31 of the emulsion nozzle 3 is surrounded by the combustion supporting gas and the synthesized oxide powder is prevented from coming into contact with the jetting end opening 31. Thereby, the oxide powder is not accumulated on the jetting end opening 31 of the emulsion nozzle 3 and the combustion is sustained.

Filed: 1980-11-10
Abstract: PURPOSE:To obtain the colorful temperature sensor having a simple structure without using a light deflecting plate and the like by utilizing the fact that liquid crytal composition including a dichroism coloring matter reversibly  changes the color before and after a transparent point. CONSTITUTION:A liquid crystal cell is formed by a glass substrate whose surface is oriented and processed by rubbing the surface in the specified direction. For example, the liquid crystal composition comprising the liquid crystal (transparent point, 51 deg.C) shown by the equation I and the dicroism coloring matter (lambdamax; 590nm) shown by the euquation II is filled in the liquid crystal. When the temperature is increased from a room temperature, the color of the cell changes from blue to purple at the vicinity of 51 deg.C. By utilizing said phenomenon, a plurality of liquid filling parts are provided between the substrates 9 and 9 (numeral 10 is a spacer and 11 is a white reflecting plate). Thirteen kinds of the liquid crystal composition whose transparent points are 10 deg.C, 12 deg.C,...34 deg.C are filled in said filling parts. Thus the thermometer can be constituted (the numerals on the filling parts are the transparent points of the liquid crystal, i.e. free air temperature).

Title: Pulse generating circuit
Inventor: SUZUKI KAZUTO
IPC: H03K5/04
Filed: 1983-08-31
Abstract: PURPOSE:To obtain a pulse generating circuit where a response speed is high and the short-circuit of an input signal supply terminal is prevented, by using a pair of delay means and feeding back their delay signals to delay means of each other and feeding back an input signal through a switching means. CONSTITUTION:When an input signal Si is 0, a transistor TRT12 is turned off and a TRT11 is turned on through delay circuits 31 and 32 and NOR circuits 33 and 34, and therefore, an output P is 1. When the signal SI is 1, the output P is changed to 1 because TRs are not turned off momentarily. After a certain time, TRs T11 and T12 are inverted, and the output P becomes 0. Since TRs T11 and T12 are not turned on simultaneously, the shortcircuit of the signal input terminal is prevented. Further, a pulse having a high response speed is obtained.
