PURPOSE:To make it possible to weld materials to be welded by efficiently transmit supersonic wave energy to said materials by a method wherein liquid is fed in a tapered cover equipped at one surface of a supersonic oscillator and at same time supersonic waves are emitted together with the liquid from the fine hole at the tip of the cover opposing to the materials to be welded. CONSTITUTION:First...

PURPOSE:To quickly cope with the fluctuation in the load on a combined cycle in which a gas turbine, an electricity generator and a steam turbine are coupled to an identical shaft, by controlling the output of the steam turbine depending on the difference between a set lead level and the output value of the electricity generator. CONSTITUTION:In a combined-cycle power plant, a gas turbine 2 is ope...

PURPOSE:To prevent a changeover shock of a clutch, by both controlling a connection speed of the clutch, changed through hydraulic operation, in accordance with the operating condition of an engine and regulating the speed of the clutch at its control so as to remove an influence of the viscosity of oil. CONSTITUTION:The captioned speed change gear has two input shafts 2, 3 connected to an engine ...

In a process for gasification of solid carbonaceous material such as coal, powdered coal is top-blown onto a molten iron bath stored in a furnace through a non-submerged lance toward a hot spot formed by means of a jet of oxygen and steam top-blown through a non-submerged lance, the coal being blown by means of a carrier gas, and flux is optionally added into the furnace by the lump or blown towar...

PURPOSE:To prevent the load inversion phenomena of a steam turbine likely to occur when the load on the plant has changed by keeping the opening of a control valve, in the turbine pressure control system of a complex cycle generating plant, at a constant value in the pressure variable range. CONSTITUTION:The steam control valve makes prepressure constant control (P1) from the time t0 to t1, and th...

PURPOSE:To eliminate yielding of plumage to the surface of the thread face, etc., and prevent the deterioration of the thread quality by making the crossing angle of a pair of guide bars, which hold and guide the thread end to the knotter, to an obtuse angle including a specific angle and reducing frictional force between the thread and the guide bars. CONSTITUTION:The sector gear 21 swings to the...

PURPOSE:To allow a simple and easy change of electrode number by intermittently rotating a rotary table to supply successively and alternatively electrodes and separators from feeders mounted at the periphery of the table and to automatically stuck up the same until a predetermined numbers of electrodes and separators. CONSTITUTION:Electrode and separator feeders and a number detector, 2 to 8 are ...

PURPOSE:To reduce the thermal stress caused in a steam turbine, by closing a fuel stop valve for a gas turbine after the main steam control valve is closed completely in a combined plant consisting of a gas turbine, a waste-heat recovering boiler and a steam turbine. CONSTITUTION:A combined plant shown in the drawing consists of a gas turbine 4, a generator 6 and a steam turbine 7 which are couple...

PURPOSE:To prolong the life of a bladder by a method wherein the thickness of the bladder is set so that sectional areas are almost tha same at various parts in the upper and lower directions at parts excluding the clamped parts of the bladder. CONSTITUTION:The bladder 10 is molded so that its thickness increases as sections of the bladder approach the upper and lower clamped parts 10a, 10b. The t...

PURPOSE:To obtain a structure for attaching a sub-transmitting case wherein when an external force is exerted to a working apparatus, fitted sections of both of the shafts of cases are prevented from being disengaged, by providing a holding fitment for abutting and holding at an end position opposite to the secured and connected side of a case. CONSTITUTION:An output shaft 14 of a main body side t...

Disclosed is a process for fabricating a composite polycrystalline diamond or cubic boron nitride (CBN) compact. Briefly, the process is conducted by mating a pre-formed sintered polycrystalline diamond or CBN compact and a plastically deformable support, and subjecting the mated composite compact to elevated temperature and pressure conditions sufficient to plastically deform the support into att...
