Provided is an electron beam irradiating device capable of emitting an electron beam from an electron beam generation source surrounded by a vacuum chamber to outside of the vacuum chamber through an electron beam exit window. The electron beam exit window includes: a grid; a window foil allowing the electron beam to pass therethrough; and a frame-shaped pressing member pressing the window foil against the grid. The surface of the grid has a groove section having an annular shape. A metal gasket is pressed between the groove section and the window foil.

A nozzle-type electron beam irradiation device includes a vacuum chamber, an electron beam generator disposed in the vacuum chamber, and a vacuum nozzle that is connected to the vacuum chamber so as to guide an electron beam from the electron beam generator and emit the electron beam to the outside. The nozzle-type electron beam irradiation device includes a high-vacuum pump capable of sucking gas from the vicinity of the connecting part of the vacuum nozzle in the vacuum chamber.

An internal surface electron beam-irradiating device sterilizes the internal surface of a vial by irradiation with an electron beam. The internal surface electron beam-irradiating device includes an electron beam generator that generates the electron beam, a vacuum chamber containing the electron beam generator, an output window that emits the electron beam to the outside of the vacuum chamber, and an extension nozzle that guides an electron cloud formed by extending the electron beam emitted from the output window. The extension nozzle includes a leaking section that leaks the electron cloud. The leaking section includes empty portions that discharge part of the electron cloud to the outside, and a component portion that guides the electron cloud into the leaking section.

A system for removing a thin metal film is disclosed. The system comprises an inclined metal plate electrode for guiding a downward electrolyte flow, an auxiliary electrode placed on either the upstream or downstream side of the metal plate electrode such that a part of the auxiliary electrode is immersed into the electrolyte, and a power supply for applying a DC voltage to the both electrodes. The system is used to remove a metal thin film on the surface of an insulator by making the electrolyte flowing down the metal plate electrode strike against the metal thin film while the DC voltage is applied to the metal plate electrode and auxiliary electrode.

A first and second electrostatic sorting sections are arranged below a tribo-electrifying device in this order in a vertical direction to form a sorting electrostatic field between a drum electrode and an opposing electrode. Plastic pieces separated from the other plastic pieces by the sorting electrostatic field in the first electrostatic separating section are introduced into a sorting electrostatic field in the second electrostatic separating section for second separation, thereby increasing the separation purity and recovery rate of plastic pieces.

Apparatus for separating plastic chips

A composite sorting apparatus for separating conductive materials from non-conductive materials comprising a drum electrode, needle-shaped electrodes, and a plate-shaped electrode, wherein the plurality of needle-shaped electrodes are arranged so that the interval X in cm (in) between discharge sections of adjacent needle-shaped electrodes with respect to the distance L in cm (in) from the tips of discharge sections to the drum electrode meets 0<X/L &lE;3.

Composite separator

A feed tray ( ) for guiding tribo electrified plastic pieces ( ) to a drum electrode ( ) is provided with a vibrator ( ), thereby making it possible to vibrate the plastic pieces ( ) to form a thin uniform layer, and to reliably apply appropriate image force and centrifugal force to the plastic pieces ( ) fed to the drum electrode ( ); thus, the plastic pieces ( ) can be separated according to kind with high precision.

Plastic sorter

A device for electrostatically separating different kinds of crushed plastic pieces and correctly sorting them according to kind. The device has a classifying section ( ) for classifying plastic pieces according to size, a frictional charging device ( ), a pair of drum type electrostatic separating devices ( ), and collecting sections ( ) disposed below the electrostatic separating devices. Partition walls ( ) for partitioning the collecting sections are constructed to be horizontally movable according to the fall positions associated with the polarity and amount of electric charge of each plastic piece ( ). Therefore, separation can be correctly effected without changing the voltage from a high voltage power source device ( ).

Plastic chip separator

A conveyor ( ) feeds batches of plastic chips ( ) in feeding amounts W to a charging device ( ). After the plastic chips ( ) have been stirred and charged inside the charging device ( ) for a certain period of time T, they are ejected in batches and fed continuously by a screw feeder ( ) to a drum electrode ( ) at a feeding amount per unit time W . The feeding amount per unit time W is adjusted so as to satisfy W /T&lE;W &lE;v&times;B&times;H&times;D where v is the rotation speed of the drum electrode ( ), B is a width of the drum electrode ( ), H is an average thickness of the plastic chips ( ) that have been fed onto the drum electrode ( ), and D is a bulk density of the plastic chips ( ).

The present invention provides an apparatus to prevent the entrance of aquatic species into the intake watercourse having a U-shaped cross section with a narrow bottom and a wide surface, in which oppositely facing electrodes are installed vertically along the side walls on both sides of the intake watercourse, and the distance between the upper ends of the electrodes is made greater than the distance between the lower ends of the electrodes, and a voltage is impressed between the both electrodes. Since the electric barrier intensity is smallest at the surface of water and becomes greater as it goes toward the bottom of water, the river fish moving around the bottom of water make a U-turn when they reach the strong electric barrier, or alternatively, after reaching the strong electric barrier, they move upward to where the electric barrier is weaker and then make a U-turn, thereby the entrance of aquatic species into the intake watercourse can be prevented.
