Abstract: The present invention provides a cooling medium flow path for improving cooling efficiency of a cooling medium used for liquid-cooling systems for motors, radiators and the like. The cooling medium flow path according to the present invention is capable of increasing cooling efficiency of a cooling medium by providing magnetic members for generating a magnetic force in a direction substantially perpendicular to the flow direction of the cooling medium so that clusters of a liquid, such as cooling water, antifreeze liquid or the like flowing through the flow path may be finely divided or activated.

Abstract: A semiconductor pellet comprising first and second semiconductor chips being diced from a wafer, a first bonding-pad formed at a first peripheral portion of said first chip, and a second bonding-pad formed at second peripheral portion of said second chip, which bonding-pads are arranged so as to keep symmetry after rotating around the central point of said pellet by 180 degrees. Judging whether the first chip is good or not and if the chip is not good, then the pellet is rotated around the central point thereof by 180 degrees, and it is mounted onto a chip carrier. Then wire-bonding is conducted.

Abstract: A control system of coal pulverizer associated with a rotary classifier, applicable to a pulverized coal burning boiler or the like, includes a function generating section, a computing section, and a rotational speed controlling section. The function generating section receives a signal representing a coal feed rate and outputs signals representing a preset proper range of a current to be fed to the motor of the coal pulverizer for such coal feed rate. The computing section is responsive to a signal representing the current motor current and the signals produced by the function generating section to output a command signal which will maintain the speed of the rotary classifier when the motor current represented by the motor current signal is within the proper range, and to output a command signal which will decrease or increase the speed of the rotary classifier, respectively, in the case where the same motor current has increased or decreased beyond the proper range.

Abstract: In a color cathode-ray tube, only a foreign matter adhering to a shadow mask is removed effectively without thermal deformation of the shadow mask or thermal denaturation of phosphors.An electron beam produced by an electron gun incorporated in a cathode-ray tube itself is scanned or irradiated to all over a shadow mask of the color cathode-ray tube. The radiant state of a fluorescent screen at this stage is checked to detect a foreign matter adhering to the shadow mask. The electron beam is deflected to align with the position at which the foreign matter is detected, and then irradiated to the foreign matter in the form of pulses. Thus, the foreign matter is heated and removed.

Abstract: An apparatus for the high voltage treatment for a cathode ray tube including a neck having one end closed with a stem and housing an electron gun and stem pins for a focus electrode and other electrodes of the electron gun, establishes a high pressure gas atmosphere around the neck, and establishes a voltage which is sufficiently higher than the operating voltage of the cathode ray tube between the stem pins when the high pressure gas atmosphere. In order to prevent a creeping discharge due to the voltage applied to the stem pins, the temperature of the neck is maintained above the temperature of said high pressure gas atmosphere during the voltage application. In an alternative method, the dew point of the high pressure gas atmosphere is set at, at most, 25.degree. C.

Abstract: Raw coal is caused to fall through a coal feed pipe and onto a table so as to be pulverized by a roll. Fine coal particles and coarse coal particles resulting from pulverization are moved upward between an auxiliary classifier cone and a mill casing by hot air supplied from below the mill casing. The hot air (upward stream) carrying the fine coal particles and the coarse coal particles moves across a space of triangular cross section formed between the inverted conical body of the auxiliary classifier cone and the side wall of the mill casing and is forced through blowoff openings defined between deflector plates so as to flow as a lateral rotative stream toward a rotary classifier. Upon impinging the downward-inclined rotating vanes of the rotary classifier, the coarse coal particles are sprung back toward a lower portion of the auxiliary classifier cone and are separated from the fine coal particles.

Furthermore, a method for preventing the explosion of a coal pulverizer which comprises the step of introducing an inert medium into the coal pulverizer in specific operation stages so that an oxygen concentration in the coal pulverizer may be in the range of from 13% to 15%.

Abstract: The known pulverized coal combustion method including the steps of separating pulverized coal mixture gas ejected from a vertical type coal grinder into thick mixture gas and thin mixture gas by a distributor, and injecting these thick and thin mixture gases, respectively, through separate burner injecting ports into a common furnace to make them burn, is improved so as to reduce both an unburnt content in the ash and a nitrogen oxide concentration in exhaust gas while maintaining an excellent ignition characteristic. The improvements reside in that an air-to-fuel ratio of the thick mixture gas is regulated to within the range of 1-2, while an air-to-fuel ratio of the thin mixture gas is regulated to within the range of 3-6, and the range of a degree of pulverization of the pulverized coal is regulated to 100 mesh residue 1.5% or less.
