Abstract: An electron beam detecting device detects a state of an electron beam radiated by an electron beam radiation device. A plurality of wire electrodes, which are conductors, are disposed corresponding to a plurality of filaments, the wire electrodes being electrically insulated from each other, in the area in which the electron beams are radiated. The electrical current flowing through each of the wire electrodes is measured by an electric current measuring instrument (measuring unit). A CPU (determining unit) determines the radiation level of the electron beams by receiving a signal output by the electric current measuring instrument. The CPU judges that when the measuring instrument measures a decrease of the current value, an abnormal condition exists in the filament corresponding to the conductor with the lower current value.

Abstract: There is provided an electron beam sterilizer judging, in an electron beam irradiation zone, whether an electron beam amount to be irradiated to a resin bottle is proper or improper. The sterilizer includes an electron beam irradiator for irradiating the resin bottle with an electron beam through an irradiation window and a bottle conveyer for conveying the resin bottle, and the resin bottle conveyed in front of the irradiation window is irradiated with the electron beam to thereby sterilize the bottle. A beam collector is disposed in front of the irradiation window so as to oppose thereto. The beam collector is supported in an electrically insulated manner by an insulating member. When the electron beam irradiates the beam collector, an electric current flowing the beam collector is measured by an electric current measuring device.

Abstract: A lens tube has two, first and second lenses (1, 2), a tubular lens frame (3) for holding the two lenses (1, 2), and three spacers (7) in contact with the opposite lens surfaces of the first and second lenses (1, 2). The spacers (7) are arranged so as to be in contact with curved surfaces of the first and second lenses (1, 2) and determine the distance between the first and second lenses (1, 2). The lens frame (3) has the same inner diameter between the first and second lenses (1, 2), and the spacers (7) are in contact with the inner wall of the lens frame (3). Since the lens frame (3) has the same inner diameter between the first and second lenses (1, 2), the first and second lenses (1, 2) are held with their centers perfectly aligned with each other.
