Title: Ignition distributor for internal combustion engine
Inventor: SONE MASAZUMI
IPC: F02P7/02
Filed: 1981-05-08
Abstract: PURPOSE:To decrease a level of radio noise, by forming an adhesive agent film layer, having powder of an inorganic insulating material, in at least an end part of at least either upper or lower side of a rotor electrode. CONSTITUTION:An adhesive agent film layer 16 is formed to the end upper side of a rotor electrode 15. This film layer 16 is formed in such a manner that, for instance, an adhesive agent used with water glass is mixed with powder of alumina as an inorganic insulating material, applied with this material and dried. This film layer 16 causes temperature of the electrode 15 to rise high with active emission of an electron, and a thermionic effect is activated. Accordingly, discharge voltage is lowered, and a capacitance discharge current is decreased to suppress generation of a radio noise arising from a spark discharge. Further an electric charge is stored between a conductor part of the electrode 15 and the film layer 16, and its residual charge effect loweres electric discharge voltage.

Title: Method for brazing aluminum material
Inventor: NAGASHIMA MASAHIKO
IPC: B23K35/363
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To well braze and join both Al material surfaces by adhering powder of SiO, powder of FK and a flux of a fluoride system to the surface of an Al material, bringing the surface of the Al material and the surface of another Al material into contact with or making them close to each other and heating both materials in this state to a temp. slightly lower than the melting temps. of the Al materials. SOLUTION: Even if clearances exist between the Al materials to be brazed to each other, the brazing property equal to that of a brazing method using Si is obtainable with the brazing method for the Al materials. More particularly the SiO is unstabler than SiO2 and, therefore, the SiO is liable to form gaseous SiF4 by reacting with the fluoride flux. The Si in the formed gaseous SiF4 creates an alloy in the surface parts of the Al material and creates the brazing filler metal which is an Al alloy of a low m.p. The brazing filler metal brazes the adjacent Al materials to each other. The SiO is preferably incorporated at 5 to 10 wt.% into the mixture and the KF at 10 to 15 wt.% and the balance is composed of the flux.

Title: Acceleration pump for carburetor
Inventor: ISHIKAWA RIYOUSUKE
IPC: F02M7/08
Filed: 1984-04-06
Abstract: PURPOSE:To deliver fuel slowly thus to improve the acceleration performance, in a system where the fuel is delivered through a plunger pump interlocked with the accelerator to the acceleration nozzle, by coupling an accumulator in the way of fuel path communicating with said nozzle. CONSTITUTION:Upon opening of an accelerator through abrupt operation, a lever 4 will correspond to push down a pump 2 abruptly thus to deliver the fuel in a pump chamber 1 to the fuel path 5. The fuel in the fuel path 5 is delivered through an acceleration nozzle 7 to the intake path 6 to push down a movable ball 11 and enters into an accumulation chamber 10. Consequently, the amount of fuel to be delivered through said nozzle 7 is reduced by the amount entering into said chamber 10 and delivered slowly. Thereafter, downward motion of pump 2 will stop to return the ball 11 through the resiliency of a spring 12 thus to return the fuel in said chamber 10 into the fuel path 5 and deliver thrugh said nozzle 7. Consequently, even upon abrupt lowering of pump, the fuel is delivered through said nozzle 7 slowly for long interval.

Title: Production of unidirectionally solidified casting
Inventor: MORIKAWA MINORU
IPC: B22D27/02
Filed: 1981-05-11
Abstract: PURPOSE:To produce unidirectionally solidified castings of less disturbance in crystal  bearings at a high production speed by suppressing the convection in the molten metal  in a mold by means of magnetic fields or the like thereby making the crystal growth directions more uniform than heretofore. CONSTITUTION:Molten metal 4 is charged into a mold 3 disposed in a furnace body 2  heated with heating bodies 1, and a chiller 5 in the bottom part is cooled to cool the  molten metal, thereby allowing the crystal to grow upward on the chiller 5. On the  other hand, the mold is heated from the upper and lateral sides of the mold 3, and therefore the molten metal is allowed to solidify perpendicularly and unidirectionally  from below to above. The front surface 7 of the solid phase is located always near the  bottom end of a furnace body 2 by lowering the chiller 5 gradually downward with a  vertically moving table 6. As a result, the upper part is heated and the lower part is  cooled with the surface 7 as a boundary, whereby a large temp. gradient is created  and directional solidification is accelerated. The conduction of a conductor, that is, the  convection of the molten metal 4 is suppressed by generating static magnetic fields in  the inside and outside parts of the body 2 by means of electromagnetic coils 8 with  iron cores disposed around the body 1, whereby the intended unidirectionally solidified  casting is produced.

Title: Functional copper alloy
Inventor: YOKOTA MINORU
IPC: C22C9/04
Filed: 1980-05-24
Abstract: PURPOSE: To provide functional characteristics such as a shape memorizing effect or superelastic behavior by preparing an alloy composition consisting of a specified amount of Zn, a specified amount of B and the balance Cu.  
     CONSTITUTION: This alloy consists of, by weight, 38W45% Zn 0.001W0.1% B and the balance Cu, 10W35% Zn, 0.001W0.1% B, <12% Al and the balance Cu, or 10W45% Zn, 0.001W0.1% B, one or more among Si, Sn, Mn, Ag, Ni, Mg, Sb, Ga, Ge, In, etc. in a range where the alloy has a β-phase structure, and the balance Cu. The reason why the Zn content is regulated to 10W45% is that <10% Zn hardly produces a functional effect and >45% Zn deteriorates the workability. When the B content exceeds 0.1%, the effect of improving the ductility becomes insufficient, and <0.001% B causes a change in the transformation temp. zone.
