摘要： Excitation current of an electromagnet coil is changed in response to a change in ambient temperature and, even if a sensor that measures the ambient temperature fails, turn-on operation can be normally realized (completed).
An electromagnetic operation device of the present invention includes an electromagnet coil for forming an electromagnet; a capacitor accumulating energy for exciting the electromagnet coil; and a control circuit for causing the electromagnet coil and the capacitor to be electrically connected according to a turn-on command or a turn-off command to a switching device; wherein the control circuit includes a limiting resistor at the time of turn-on operation, and a short-circuiting mechanism that is provided in parallel with the limiting resistor at the time of turn-on operation and short-circuits the limiting resistor at the time of turn-on operation by using a normally-closed contact point that is normally "closed" and is "opened" when a signal is inputted.-

摘要： A heat radiator for a solid insulated switchgear unit reduces thermal resistance in a connection part between a main circuit conductor and a heat radiator, and improves attachment workability. The heat radiator, attached to a bushing conductor of the solid insulated switchgear unit, includes: a heat radiation member of metal material having a connection part with a bolt through hole; a housing of solid insulation material having a head part in which the bushing conductor is inserted and an insulation plug insertion part in which the insulation plug is inserted; and a bolt which fastens the heat radiation member to the bushing conductor. The insulation plug insertion part and the head part communicate with each other. The bolt is inserted from the insulation plug insertion part side, through the bolt through hole of the connection part projected to the inside of the head part.

摘要： To obtain a printing inspection device that an optimum binarization threshold value in the printing inspection device that captures an image including a two-dimensional code printed by a general-purpose printer such as an ink jet printer, as a multi-level image, creates a binary image from the multi-level image with a predetermined binarization threshold value, and then performs decoding. Before a practical printing inspection is performed, a read test is performed. The read test is performed on one or more inspection samples by binarizing a multi-level image with brightness values for all gradations as a threshold value. A range (maximum value and minimum value) of readable brightness values is obtained, and then a median value between the minimum value and the maximum value is used as a binarization threshold value for a two-dimensional code image in a practical printing inspection.
