  • Patent number: 12220925
    Abstract: A recording apparatus includes a carriage, a tank, a flow passage, and a valve. The carriage includes a recording head that ejects liquid contained in the tank and supplied from the flow passage. The flow passage includes (i) a fixed flow passage connected to the tank without following a movement of the carriage, (ii) a first flow passage that follows the movement of the carriage and is branched off from the fixed flow passage and connected to the recording head, and (iii) a second flow passage that follows the movement of the carriage and is branched off from the fixed flow passage and connected to the recording head. The valve is provided in one of the first and second flow passages and limits a flow of liquid from the tank to the recording head and allows liquid to flow from the recording head to the tank.

  • Patent number: 12202057
    Abstract: According to one implementation, a drill includes the first cutting edges, the second cutting edges and a deflection reducer. The first cutting edges drill a prepared hole to a workpiece. The first cutting edges are formed in a tip side of the drill. The first point angle and each first relief angle of the first cutting edges continuously or intermittently decrease from the tip side toward a rear end side of the drill. The second cutting edges finish the prepared hole. The second cutting edges are formed at positions away in the rear end side from the first cutting edges. The second cutting edges have the second relief angles at a maximum diameter position. The deflection reducer reduces deflection of the second cutting edges. The deflection reducer is formed between the first cutting edges and the second cutting edges. The deflection reducer is inserted into the prepared hole.
