Abstract: It is to provide a novel benzamide compound useful as an active ingredient of a herbicide, the benzamide compound exhibiting a definite weed control effect even in a small amount, having low phytotoxicity to crops, and having high safety in environments, and a herbicide. A compound of the present invention is a compound of formula (II) or a salt thereof.

Abstract: The present invention relates to a method for controlling weeds while reducing harm to a beneficial plant caused by a herbicidal ingredient by applying a safener composition containing picarbutrazox and the herbicidal ingredient or by applying the herbicidal ingredient while applying picarbutrazox, during the cultivation of the beneficial plant such as lawn grass, wheat, maize, rapeseed, rice, and soybean.

Abstract: A contact device includes: fixed terminals; a movable contact maker; a pressing spring; an adjustment plate that comes into contact with an upper face of the movable contact maker; a holding portion; a movable shaft; and an electromagnet block. The holding portion is divided into first and second holding portions that are separated from each other. The first and second holding portions are electrically connected to each other via only the adjustment plate, due to the adjustment plate being sandwiched by a first side plate of the first holding portion and a second side plate of the second holding portion. The adjustment plate is moved in extending and contracting directions of the pressing spring, and the adjustment plate and each of the first and second side plates are subjected to resistance welding at a position at which pressing force of the pressing spring is a predetermined value.

Abstract: A contact device includes a contact point block, a drive unit, and permanent magnets. The contact point block includes fixed terminals having fixed contact points and a movable contactor having movable contact points arranged side by side on one surface of the movable contactor. The movable contact points are configured to come into contact and out of contact with the fixed contact points. The drive unit drives the movable contactor such that the movable contact points come into contact and out of contact with the fixed contact points. The permanent magnets are arranged in a mutually opposing relationship across the contact point block along a direction orthogonal to an arrangement direction of the movable contact points and to a direction in which the movable contact points come into contact and out of contact with the fixed contact points. The permanent magnets are provided with mutually-opposing surfaces having the same polarity.

Abstract: A contact apparatus includes a case; fixed terminals having the fixed contacts arranged within the case; a movable contact member having the movable contacts provided on one surface thereof so as to come into contact or out of contact with the fixed contacts; a first yoke arranged on said one surface of the movable contact member within the case, one surface of the first yoke facing an inner surface of the case and the other surface thereof facing said one surface of the movable contact member; and a second yoke arranged on the other surface of the movable contact member within the case, the second yoke having one surface facing the other surface of the first yoke through the movable contact member. The first yoke is larger in volume than the second yoke.
