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.
摘要:
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. The rotational speed controller receives the command signal and regulates the speed of the rotary classifier on the basis of the command signal.
摘要:
A medium feeding device is adapted to be attached to a recording apparatus to feed a recording medium thereto or adapted to be attached to a liquid ejecting apparatus to feed a target medium thereto A first tray is provided with a hopper adapted to support the recording medium or the target medium which is to be automatically fed to the recording apparatus or the liquid ejecting apparatus by a feeding roller. A second tray is arranged above the first tray and adapted to support the recording medium or the target medium which is to be manually fed to the recording apparatus or the liquid ejecting apparatus. The second tray includes a tray body and an extensible member which is retractably extended from the tray body toward the feeding roller.

摘要:
There is introduced a wireless network system which can establish a complicated wireless network without cumbersome tasks. Arranged hierarchically, wireless terminal a is wire-connected to a master apparatus M, and wireless terminals b, c, d, e, f, g, h, and the like are wire-connected to slave apparatuses A, B, C, D, E, F, G, H, I, and the like. Wireless terminal a outputs a command outputted from the master apparatus M to wireless terminals c and the like whose ranks are immediately below that of the wireless terminal a. Wireless terminal c transmits the command directly or indirectly to wireless terminals d and the like whose ranks are immediately below that of the wireless terminal c. Wireless terminal d communicates with slave apparatus B through a wire, and returns a response from the slave apparatus B to the master apparatus M via wireless terminal c and wireless terminal a.

摘要:
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.
摘要:
A mill inert apparatus for preventing the explosion of a mill inert apparatus which comprises a drain separator and a drain trap for separating and removing drain contained in an inert vapor, and a drain discharge route for discharging the separated drain. 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%.
