20120041313 | ULTRASONIC IMAGING DEVICE - The absolute pressure inside the heart with respect to heartbeat time phase is measured non-invasively or with minimal invasion. An ultrasonic diagnostic device comprising: a pressure sensor that detects artery pressure non-invasively; a reference pressure computation part that converts the artery pressure into absolute reference pressure with respect to a reference point; a spatial pressure difference calculation part that calculates a spatial pressure difference between the reference point and a location distinct from the reference point; and an absolute pressure computation part that calculates intracardiac absolute pressure using a shape image, the reference pressure, and the spatial pressure difference. | 02-16-2012 |
20120082579 | INTERNAL-GEAR TYPE FLUID DEVICE - In an internal-gear type fluid device, guide teeth are formed by inner teeth at an outer rotor, and vane portions extending in the width direction are formed at tooth tip portions of the guide teeth. Further, guide teeth are formed by outer teeth at the inner rotor, and vane portions extending in the width direction are formed at tooth tip portions of the guide teeth. Since the vane portions are thus formed at the outer rotor and the inner rotor, the confinement timing when oil confinement is completed can be synchronized with the release timing when oil release is started, by adjusting, for example, the thickness of the vane portions without changing the profile of the guide teeth. | 04-05-2012 |
