Abstract: An inspection apparatus comprises a first channel that passes an aqueous sample therethrough, a second channel that passes a phosphate eluent therethrough, a separation device that separates by size a group of substances contained in the aqueous sample, and a TOC device that oxidizes each substance separated by the separation device by size and measures organic carbon contained in each substance. The separation device includes a column for size-exclusion chromatography and a sample injection unit that introduces the aqueous sample into a mobile phase passed through the first channel. The second channel is connected to the first channel between the column and the sample injection unit, and causes the phosphate eluent to merge with the aqueous sample between the sample injection unit and the column.

Abstract: An object is to increase an efficiency of removing carbon dioxide derived from inorganic carbon. An inspection apparatus includes: a column that separates a group of substances contained in an aqueous sample by size; an addition unit that adds a reagent, which acidifies the aqueous sample, into a channel; a degassing unit provided downstream of the addition unit for degassing carbon dioxide; a measurement unit that measures organic carbon contained in each substance from which the carbon dioxide has been removed; and a temperature maintaining unit that maintains a temperature of each of the column and a container in which a gas-permeable tube of the degassing unit is housed.

Abstract: A valve timing adjusting device includes an intake variable valve mechanism and an exhaust variable valve mechanism. The exhaust variable valve mechanism includes an exhaust electric driving portion and an exhaust phase shifting portion including an input shaft. The exhaust phase shifting portion is disposed in a rotation transmission path between an exhaust camshaft and a crankshaft and configured to shift a rotation phase of the exhaust camshaft. The input shaft rotates in a rotational direction opposite to a rotational direction of the crankshaft when advancing the rotation phase. A phase of the exhaust phase shifting portion is configured to be shifted to a most advanced angle phase when the exhaust electric driving portion is de-energized or fails and when the exhaust phase shifting portion receives a torque in a forward rotational direction.

Abstract: A driven-side rotator is rotatable synchronously with a camshaft and is supported between a gear member and a sprocket member of the driving-side rotator in an axial direction. A stopper portion of the driven-side rotator is adapted to contact the driving-side rotator in a rotational direction to limit a change in a relative phase between the crankshaft and the camshaft. The stopper portion radially outwardly projects from a small diameter portion provided at one end part of the driven-side rotator. A large diameter portion is provided at the other end part of the driven-side rotator and has a radial size that is measured from a rotational axis to a radially outer peripheral surface of the large diameter portion and is equal to or larger than that of the stopper portion.

Abstract: A fuel injection valve includes a valve body having a valve seat, a nozzle plate arranged on an injection side of the valve body, a valve plug for intermitting fuel injection through the nozzle hole, and a sleeve. The nozzle plate has a nozzle hole through which fuel is injected from the injection side of the valve body. The sleeve makes contact with an end surface of the nozzle plate on an opposite side of the valve body with respect to the nozzle plate to partially cover the nozzle plate. Fuel is injected to an outside of the sleeve through the nozzle hole of the nozzle plate and an opening of the sleeve. The end surface of the nozzle plate makes contact with the sleeve in a contact portion. The contact portion has at least one groove that extends from the opening outwardly with respect to a substantially radial direction of the sleeve.
