An X-ray inspection apparatus is used for an inspection of a substrate, and the X-ray inspection apparatus includes an image acquisition unit that acquires a plurality of tomographic images for the substrate, an image extraction unit that extracts, from a data set obtained based on the plurality of tomographic images, an inspection tomographic image that is a target for determining whether the substrate is acceptable or not, a saved data generation unit that generates predetermined saved data including at least the inspection tomographic image, and a saved data storage unit that stores the saved data.

The disclosure relates to a pump assembly for a vehicle having an internal combustion engine with or without transmission or electric motor with transmission or for an oil supply having a double-pipe pump, wherein the two pipes are separated from each other and a second pipe can be connected to a first pipe, wherein the pump has at least one input drive point for an electric machine and also for a drive motor, including, for example, via a gearbox.

A first communication groove (38) extending from a start point of a discharge port (36) in a direction opposite to rotation direction of vanes (22) is formed. A first end portion (38E) of this groove is connected to the start point of the discharge port (36). When a front-side vane in a rotation direction of a driving shaft (11) is positioned at the start point of the discharge port (36), a second end portion (38S) of the groove is positioned at a rear side in the rotation direction with respect to a rear-side vane coming immediately after the front-side vane, and communicates with a suction port (35). A part of working fluid in a front-side pump chamber (27-1) can therefore be introduced into a rear-side pump chamber (27-2) that communicates with the suction port (35), thereby lessening excessive pressure increase of the front-side pump chamber (27-1) and suppressing pulsation phenomenon.

A hydraulic device is disclosed. The hydraulic device can include a rotor, a plurality of vanes and a ring. The ring can include a suction cavity and a pressure cavity. The suction cavity and pressure cavity can be configured for ingress and egress of a hydraulic fluid through the ring. The ring can include a suction port defined entirely by the ring and in fluid communication with the suction cavity. The suction port can be configured to receive hydraulic fluid from a first region between the ring and the rotor. The ring can include a pressure port defined entirely by the ring and in fluid communication with the pressure cavity. The pressure port can be configured to allow for passage of the hydraulic fluid from the pressure cavity to a second region between the ring and the rotor.

An internal gear pump includes a pinion, a ring arranged around the pinion, and a cylindrical wall arranged around the ring. A support element, on which the pinion and the ring are supported, carries high-pressure liquid towards a recess located at the junction between the ring and the cylindrical wall, and also carries low-pressure liquid towards another recess located at another point of the junction between the ring and the cylindrical wall. The recess allows the load of the ring on the cylindrical wall to be reduced.
