  • Publication number: 20220361325
    Abstract: [Object] Provided is a printed circuit board ensuring a degree of freedom in circuit design and unlikely to cause a circuit connection failure. [Solving Means] A middle interlayer circuit 11, an upper surface side interlayer circuit 12, and a lower surface side interlayer circuit 13 are formed from a connection surface-less integral conductor. In addition, a connection surface 33 between the upper surface side interlayer circuit 12 and an upper surface side surface layer circuit 14 and a connection surface 34 between the lower surface side interlayer circuit 13 and a lower surface side surface layer circuit 15 lack a connection surface in a plate thickness direction, and thus a satisfactory connection state is achieved. Accordingly, a first circuit 10 is unlikely to cause a connection failure.

  • Patent number: 10549296
    Abstract: A trigger-type sprayer with excellent usability is provided capable of locking rotation of a nozzle part without using a separate component so as not to cause a nozzle orifice to be inadvertently opened. A trigger-type sprayer A of the present invention moves a piston part 3 by pulling and rotating a trigger part to compress liquid in a cylinder part and cause the liquid to be injected from a nozzle part 1 communicating with the cylinder part, and the trigger-type sprayer A includes a lock function of preventing rotation of the nozzle part between the nozzle part 1 and the trigger part 5.

  • Patent number: 10046349
    Abstract: A pump dispenser includes a housing, a piston structure, a spring, a trigger and a valve. The housing has a front cylinder part and a rear inverted-L-shaped grip part that are integrally formed, a nozzle base that is attached to the housing and that has a front nozzle part mounted thereon. The piston structure is configured of a hollow-shaped piston and a hollow-shaped piston shaft and that slides inside the cylinder part. The spring presses the piston structure upward. The trigger is positioned above the housing, has a front tip rotatably mounted on the housing, and has a mid part where a tip of the hollow-shaped piston shaft abuts. The valve rod is disposed at a center part of the cylinder part.
