    • There is disclosed a coaxial lightning arresting structure comprising an inner conductor, an outer conductor surrounding the inner conductor and an arrester tube located between the inner and outer conductors perpendicularly to the direction of transmission and connected at its ends to the inner and outer conductors, respectively. The portion of the inner conductor provided with the arrester tube has a reduced effective sectional area as compared with the other portions of the inner conductor so that the ratio of the outer conductor inner diameter to the outer diameter of the inner conductor portion having the reduced effective sectional area is greater than the ratio of the outer conductor inner diameter to the inner conductor outer diameter at the other portions of the inner conductor which latter ratio provides the coaxial transmission line with a given characteristic impedance.

    • A method for detecting a hopper insertion state for a bag-filling packaging machine using photoelectric sensors 7 provided at an item supply step position. The photoelectric sensors 7 detect deformation of the bag mouth that occurs when the hopper 4 is inserted into the bag mouth, and a decision whether the insertion status of the hopper 4 in the bag mouth is good or bad is made based on the detection result of the photoelectric sensors 7. If the tip end of the descending hopper 4 catches the bag mouth or presses the bag mouth and folds it, the bag face is moved away from the detection part 9 (light passage route) of the sensors 7, so that light from the light-emitting part of the sensors 7 reaches a reflecting mirror 6 and reflected, and the reflected light is detected by the light-receiving part of the sensors 7.
