摘要:
The invention utilizes vibration control, precision manufacturing tolerances for certain components of the system, and techniques for limiting thermal expansion of components, including passive insulation and active cooling techniques, in order to enable high speed tool rotation for Friction Stir Spot Joining of Advanced High Strength Steels.
摘要:
A disc driving device of the type in which two different head units are moved by a linear motor along the radial direction of two discs having different recording densities. If a floppy disc with the standard recording density (lower order mode) is loaded on a disc table and a shock sensor detects the shock, a controller discontinues the recording and/or reproducing processing by a FDD (Floppy Disk Drive).
摘要:
A waste substance such as toxic compounds used in chemical weapons and industrial wastes including incineration ash is treated by a thermit reaction agent by way of supplying the waste substance to a combustion region of the thermit reaction agent or by adding way of heating the blended material comprising the waste substance and thermit reaction agent. The waste substance is fed into the combustion region of a thermit-type hypergolic fuel containing as its principal component a thermit reaction agent composed of an aluminum powder and a metal oxide powder, thus breaking down such a waste substance using the combustion heat of the thermit-type hypergolic fuel. The waste substance can be blended with a thermit reaction agent and fed into a combustion chamber so that the blended material is heated by way of a burner, so that the blended material is directly heated by a burner during the continuation of thermit reaction following the start of the thermit reaction of the thermit reaction agent. The heating of the blended material is executed by way of the surface heating by the burner and the thermit reaction heat generated inside the blended material.
摘要:
In a fuel injection apparatus for multi-cylinder engines, the apparatus has a signal generator for generating an electric signal representing an operating condition of the engine, a decision circuit for determining the cylinder or cylinders of the engine to be used in accordance with the electric signal, a control device which is responsive to the output of the decision circuit and selects the cylinder or cylinders of the engine to which fuel injected from a fuel injection pump is to be supplied, and a control circuit for regulating the control of the amount of fuel injection from the fuel injection pump on the basis of a governor characteristic determined in accordance with the output of the decision circuit, whereby the engine can be operated in the skip-cylinder mode more stably than in the case of the conventional apparatus.
