Latest Patents.

“Cylinder block with detected portions and hydraulic device including same” describes a cylinder block with multiple cylinder chambers arranged around a rotating shaft. Its outer surface has first detected portions spaced at a predetermined interval and one or more second detected portions spaced from adjacent first portions at a different interval. This arrangement enables the detected portions to be distinguished as the block rotates.

“Hydraulic system” combines a hydraulic device with a determination device. The hydraulic device includes a casing, a cylinder block with the described detected portions, a piston, a linkage mechanism, and sensors positioned to detect the portions as they pass. The sensors output one of two signals, and the determination device uses those outputs to assess whether the cylinder block is a suitable product.

Career Highlights.

Okada’s listed patent work focuses on applying distinct spacing patterns and sensor signals to hydraulic equipment. These features support detection and product suitability determination during cylinder-block rotation.
