摘要:
A variable venturi-type carburetor comprising a suction piston and a needle. The root portion of the needle is fixed onto the central portion of the tip face of the suction piston. An annular groove is formed on the tip face of the suction piston around the root portion of the needle. A narrow groove is also formed on the tip face of the suction piston and extends downwardly from the annular groove to the downstream end of the tip face of the suction piston.

According to the present invention, there is provided a device for diagnosing malfunction in a fuel tank. The fuel tank has a separator wall therein which separates an interior of the fuel tank into a fuel chamber and an air chamber. The separator wall is deformable according to an amount of fuel in the fuel chamber. The device comprises a device for detecting a change of at least one of a position of the separator wall, the pressure in the tank and the concentration of fuel vapor in the tank, and a device for diagnosing malfunction of the separator wall on the basis of the change to diagnose that the separator wall has malfunction when the change differs from a predetermined regular change.
摘要:
A protection structure for a surge absorbing element for protecting equipment such as communications lines from surges caused by lightning or the like which makes use of a surge absorbing element in parallel with the equipment to be protected and a low melting point metal wire in direct contact with the element and in series therewith. The structure protects the surge absorbing element or assembly from continuous overvoltage or overcurrent which may be generated by a short-circuit of an alternating electric current source and the like.

A material for valve seats comprising a wear resisting sintered ferro alloy formed by dispersing particles of a high speed steel in a matrix in which hard alloy particles are dispersed. Steps for forming include mixing particles of a matrix material, carbide material and a hard alloy, and blending the mixture with high speed steel particles, pressurizing and compacting the mixture after blending, then sintering them at 1000.degree. to 1200.degree. C. In the preferred method, at least one element of Fe, C, Ni, Co, Si or Mn is included as the matrix material, and at least one element of Fe, Cr, Mo or V as the carbide material and at least one element of Fe, Cr, Mo, Co, C or W as the hard alloy are prepared. Furthermore, the ferro alloy preferably includes the following amounts of the above mentioned elements, 0.5 to 2.0 wt % of C, 1 to 25 wt % of one or more of Cr, Mo, V, or W and 1 to 15 wt % of one or more of Co, Ni, Mn, or Si.
摘要:
A device for exterminating pests having a cylinder filled with carbon dioxide in which (a) pesticide(s) is(are) dissolved, piping coupled to the cylinder, and a plurality of capillary nozzles affixed to the piping, and a method of exterminating pests employed this device. The capillary nozzles are designed such that, considering adjacent capillary nozzles, the ratio of the nozzle exit area of the capillary nozzle close to the cylinder to the nozzle exit area of the capillary nozzle remote from the cylinder is set between 1:1.3 and 1:1.8. As a result, numerous independent enclosed spaces can be sprayed with little labor and in a short time by means of a small number of devices.
摘要:
A surge absorber utilizes a varistor electrically connected to a surge absorbing element. The varistor voltage and nonlinearity factor are chosen so that the varistor has a preselected voltage-current characteristic which prevents the varistor from breaking down and short circuiting and resulting in a thermal runaway.
摘要:
An alumina porous body which comprises coarse alumina particles as a filler and SiO.sub.2, said alumina and SiO.sub.2 forming an Al.sub.2 O.sub.3 -SiO.sub.2 compound (mullite) on the surface of the coarse alumina particles through the reaction between them that takes place at the time of firing, said compound binding said coarse alumina particles, forming pores between them. The invention also relates to a process for producing an alumina porous body which comprises mixing coarse alumina particles with SiO.sub.2, molding the mixture, and firing the molding at a temperature not higher than 1700.degree. C., thereby sintering the coarse alumina particles.
摘要:
A fuel tank comprising a fuel inlet pipe. A fuel pump nozzle is inserted into the fuel inlet pipe. A throat portion having a venturi shaped cross-section is arranged in the fuel inlet pipe between the interior space of the fuel tank and the tip of the fuel pump nozzle inserted into the fuel inlet port. Fuel spouted from the fuel pump nozzle passes through the entire cross-section of the throat portion.
