摘要:
A combustion device for a melting furnace, capable of heating a melting target object and the ceiling portion of the furnace with the radiant heat of the flame, including a combustion space above the location of the melting target object, including a fuel injection nozzle having a plurality of fuel injecting portions, which portions include orifices disposed side by side horizontally relative to the direction of fuel injection, and formed side by side vertically relative to the same. The orifices are formed radially side by side as seen laterally, with a direction along a middle angle in the angular range between the fuel injection direction of the uppermost fuel injection orifice and the fuel injection direction of the lowermost fuel injection orifice being directed obliquely upwards. The fuel injection orifices of the upper fuel injecting portion are formed radially side by side as seen in the plane view.

Provided are an ancillary material, used for shape processing, which is capable of shortening a processing time, avoiding a reduction in quality of a shape provided to a workpiece material, and allowing a relatively low manufacturing cost; a processing method using the ancillary material; and a method of manufacturing the ancillary material. The tungsten alloy grains (1) comprise: tungsten of greater than or equal to 80% by mass and less than or equal to 98% by mass; nickel; at least one kind of metal selected from the group consisting of iron, copper, and cobalt; and an inevitable impurity, a maximum diameter thereof is greater than or equal to 0.1 mm and less than or equal to 5.00 mm, and a specific surface area thereof is less than or equal to 0.02 m2/g. The tungsten alloy grains (1, 10), the workpiece material (30), an abrasive (20) are blended in a container (100) and the container is rotated, thereby processing the shape of the workpiece material (30). In the method of manufacturing the tungsten alloy grains (1), a granulated powder is stirred at a temperature greater than or equal to a softening point of an organic binder and thereafter, is cooled, thereby spheroidizing the granulated powder.

There are provided an apparatus capable of complying with arbitrary data acquisition period (frame rate) change instruction without increasing load and cost, and a method and a system for controlling such an apparatus. To realize this, in the present invention, there are included an area sensor for reading out an electric signal accumulated in a plurality of pixels arranged in a matrix, line by line, and a control unit for controlling the area sensor. The area sensor operates in a first operation for deriving radiation image data by reading during irradiation with radiation, and a second operation for deriving the radiation image data by reading during non-irradiation with radiation, alternately. The control unit switches a period for deriving the radiation image data during a time period from an end of the reading in the first operation until an end of the reading in the second operation.

摘要:
An ignition timing control apparatus can obtain high output torque without generating output torque loss, and avoid the deterioration of audibility due to successive knock occurrences. A cylinder specific ignition timing setting section includes a reference ignition timing control section, and a cylinder specific correction value setting section having correction values of the same number as that of engine cylinders. The reference ignition timing control section calculates reference ignition timing common to all the cylinders and uniformly controls the ignition timings of all the cylinders to a retard angle side to prevent the occurrence of successive knocks. The cylinder specific correction value setting section calculates cylinder specific correction values to compensate for variation in the cylinder specific optimal ignition timings, and sets the cylinder specific correction values for cylinders other than those whose knock frequency becomes equal to a predetermined value or more so as to advance their ignition timings.
摘要:
When a call-up is generated, an data type identifying unit of a CPU identifies the type of data type information which is appended as a header to received data as one of sound data, text data, and image and sound data, and displays the type on a display unit comprising a monitor. When the type is sound data or text data, an application for executing a corresponding telephone function or data communication function is activated via the user line connection. When the type is image and sound data, an application for executing a corresponding visual telephone function is activated after line connection.
