Abstract: A secondary magnetic excitation generator-motor device that inputs a first ignition pulse command to a three-level NPC power converter such that a detected excitation current value corresponds with an excitation current command value, the secondary magnetic excitation generator-motor device having a function of identifying a first phase, a second phase, or a third phase in descending order of a current absolute value, wherein a pulse switch to output an ignition pulse command to the three-level NPC power converter switches the ignition pulse command to the second ignition pulse command when a current absolute value exceeds a set overcurrent level 1, and switches the ignition pulse command to the first ignition pulse command when current absolute values for three phases are all equal to or smaller than a set overcurrent level 2.

Abstract: A binding machine comprises a cutting portion which cuts the wire, a fixed blade in which a first wire passage through which the wire passes is formed; and a movable blade in which a second wire passage through which the wire passes is formed. The movable blade includes a blade portion provided on one side of the second wire passage and a passage forming member provided on the other side of the second wire passage, the second wire passage includes a guiding portion for guiding the wire after cutting in a movement when the movable blade moves from the movement finish position to the standby position, and the guiding portion is protrudes in a direction of the guide portion and blocks a portion between the movable blade and the guide portion in a non-wire-passing-through manner when the movable blade moves to the standby position.

Abstract: A binding machine includes a reel accommodating portion, a reel brake, and a brake accommodating portion. The reel accommodating portion is configured to rotatably accommodate a wire reel. The reel brake has an engaging portion which is configured to engage with the wire reel and is configured to brake rotation of the wire reel. The brake accommodating portion covers a periphery of the reel brake except at least the engaging portion. The brake accommodating portion includes a first opening portion exposing the engaging portion and a second opening portion communicating with an outside.

Abstract: A height adjustment apparatus that can reduce a load to trim a can body is provided. The height adjustment apparatus 1 is adapted to adjust a height of a can body to a desired height by trimming one of opening ends of the can body. The height adjustment apparatus comprises: mandrels on which the can body is individually mounted and which revolve along a predetermined orbit while rotating; outer blades arranged around the revolution orbit of the mandrels; an inner blade fitted onto each mandrel to trim the opening end of the can body together with the outer blade; and a vertical reciprocator that gradually changes a level of the opening end of the can body with respect to a level at which the outer blade and the inner blade are situated from an upstream side toward a downstream side in a revolution direction of the mandrel.

Abstract: A method for inspecting sealing defects of a container using infrared light. Infrared light in a wavelength range of 1450 nm±20 nm is irradiated from a phototransmitter onto the sealed portion of a sample container Infrared light reflected from or transmitted through the sealed portion of the sample container is received by a photoreceiver, and transmitted to a photodetector through an optical fiber. The infrared light in a same wavelength range as the case of inspecting the sample container is irradiated onto the sealed portion of a container to be inspected. The infrared light reflected from or transmitted through the sealed portion of the inspected container is converted into the analog voltage value and transmitted to a controller. If the infrared light is reduced to be smaller than a threshold set on the basis of the sample container, the sealed portion of the inspected container is judged as a sealing defect.
