PURPOSE:To avoid such an improper phenomenon where the drain is injected into a combustion chamber by discharging the heated steam, which is introduced from an auxiliary steam system prior to the start of a gas turbine device, from a forced, drain discharge system, so that the drain in a steam injection pipe can be discharged in advance. CONSTITUTION:In the captioned plant, in which steam is injec...

A control system for a vehicle engine coupled with an automatic transmission, which comprises a torque controller (B5) operative to vary torque produced by the vehicle engine (1), in accordance with a controlled variable, so as to suppress torque shock resulting from a speed change operation carried out to vary a gear ratio in a power transmitting gear arrangement (20) provided in the automatic tr...

PURPOSE:To perform a quick start intended by detecting an automatic transmission for its stall condition and inhibiting action of a traction control means at the time of starting from the stall condition. CONSTITUTION:A throttle valve for adjusting an output of an engine is opened and closed by a step motor, and a number of its steps is controlled by a control circuit in accordance with a step-in ...

In a method of producing metal melts, in particular steel melts from scrap (22), in an electric arc furnace having at least one graphite electrode, organic substances (24, 26) are introduced into the arc (20) through a central longitudinal recess (14) in the graphite electrode (4), in order to reduce the electrode consumption (Figure 1).

Lead-based battery terminals (10,10') are moulded into a battery case (26) so that only the outer ends (18) of the terminal units are external to the case (26). The terminals (10,10') have elongated straps (12) internal of the case (26) slotted to receive projecting lugs (42,44) integral with positive and negative interleaved electrode plates (34-40). After the plates (34-40) and separators (55) a...

PURPOSE:To improve the high temperature service life, by making the coating thickness of an active substance paste at the parts surrounded by grids (meshes of grid) larger than that at the parts corresponding to the grids. CONSTITUTION:The paste coating thickness (the electrode plate thickness) t1 at the parts responding to grids 1 is made smaller than the thickness t2 at the parts of the meshes o...

A silicon crystal evaluation method includes the step of measuring, at room temperature, an intensity of an oxygen impurity infrared absorption peak of each of a plurality of silicon crystals at a wavenumber of 1107+/-3cm<-><1>. Each of the silicon crystals contains oxygen impurities, the silicon crystals including an evaluated silicon crystal having an unknown thermal history and reference silico...

The purpose of the invention is to detect impurities in a semiconductor wafer (20). A laser (21) forms a light beam having a high proportion of its power at an optical frequency capable of being absorbed by the impurity to be measured. The beam is split into first (25) and second (26) light components, one of which is directed at the surface of the semiconductor wafer (20) to be tested and the oth...

A device for characterizing the formation of a sheet material is described. The device comprises a basis weight sensor for measuring the basis weight of the sheet material as the material moves through the sensor and signal processing circuitry which receives a signal from the basis weight sensor indicative of the measured basis weight. The basis weight sensor includes a light source for directing...

A method of testing security papers with respect to the positions of a safety thread and water marks to detect errors in the paper is performed by a linewise scanning of a finished paper web. The web has at least two point like measuring marks inserted into it in addition to the water marks, whereby impulses which are originated from these measuring marks are evaluated and the sheet width and the ...

The invention provides an apparatus for pre-processing sensor data that represent measurements of a physical parameter of a material under inspection. Sensors are employed to provide a multiplicity of data associated with a corresponding multiplicity of small areas of the material; and a multiplicity of reference data are also generated, each reference datum being associated with a particular sens...
