Latest Patents

One of Noguchi's latest patents is a "Liquid containing gas bubbles production apparatus." This apparatus is designed to produce a liquid that contains gas bubbles and includes a casing, a pump unit, and a gas bubble-mixing unit. The casing features a main flow channel for the liquid, which has both a liquid inflow port and a liquid outflow port. The pump unit is strategically placed in the main flow channel to facilitate the movement of liquid from the inflow port to the outflow port. The gas bubble-mixing unit incorporates a first choke portion with a reduced inner diameter and a gas supply channel that feeds gas into the choke portion.

Another significant patent is the "Seal structure of crawler-driving apparatus." This invention provides a solution to block the clearance between a rotational casing and a fixed housing in a crawler vehicle. The design includes a seal ring held in a first annular holding groove within the fixed housing, along with a first O-ring that biases the seal ring outward. Additionally, a second holding groove in the rotational casing holds a slide ring, which has greater rigidity than the seal ring, along with a second O-ring that biases the slide ring toward the seal ring. This innovative design effectively prevents foreign objects, such as mud, from entering the gear chamber without increasing frictional loss.
