摘要:
The present invention provides a computed tomography system that only requires rotational scans for image pickup, the system enabling images of a plurality of testing objects to be simultaneously picked up without increasing the volume of noise or the scale of the system, thus enabling high-quality tomographic images to be efficiently picked up. In the computed tomography system, a plurality of turn tables 11a to 11d are provided in a region of irradiation with X-ray beams emitted by an X-ray irradiation system. Testing objects Ma to Md are placed on the respective turn tables. Images of the plurality of testing objects can be simultaneously picked up by irradiation with X-ray beams. This enables precise image pickup to be efficiently achieved without increasing the size of the scale.

An inspection signal to inspect forward-path or return-path communication, is transmitted from a reference node of a network. A response signal is transmitted in a priority class from a node of a forward path to the reference node. In the case of inspection of return-path communication, a replica of the response signal is transmitted in a non-priority class from the node of the forward path to the return path, and the node that receives the replica of the response signal transfers the replica in a priority class to the reference node. In the case of inspection of forward-path communication, a replica of the inspection signal is transmitted in a non-priority class from the node of the forward path to the forward path, and a replica of the response signal is transmitted in a priority class from the node that receives a replica of the inspection signal to the reference node.

The invention relates to two-component coating systems comprising as component (a) one or more polyisocyanates, as component (b) one or more oligomeric and/or polymeric compounds that are reactive with component (a), and as component (c) one or more phosphonates selected from the group of phosphonic diesters and diphosphonic diesters, where (i) component (b) comprises all oligomeric and/or polymeric compounds that are present in the two-component coating system and are reactive with component (a) and (ii) component (b) contains not more than 15% by weight, based on the total weight of component (b), of oligomeric and/or polymeric compounds which carry isocyanate-reactive amino groups. Additionally provided by the invention are a process for preparing the two-component coating systems, and the use of these coating systems as a clearcoat, more particularly for multicoat automobile finishing.
摘要:
The present invention provides operators the ability to follow a predetermined path and achieve desired digging depth by watching steering and elevation indicators of just one system. The indicators are activated by data derived from the interception of signals generated by a single laser transmitter and a receiver array mounted on the machine. The system according to the present invention uses the multiple, tilted fan beams provided by the laser transmitter to calculate elevation angle and azimuth of the tool carried by machine.

A pump unit for assisting in the blood feeding operation of a heart includes a pair of pumps 7a, 7b connected in parallel with each other. When the pump 7a (or 7b) has reached its expanded position and the pump 7b (or 7a) has reached its contracted position, the operation is changed so that the pump 7a (or 7b) is set up for contraction while the pump 7b (or 7a) is set up for expansion. A time difference TCM between the time when the expanded position is reached and the time when the contracted position is reached is determined. If TCM>Tr, a driving pressure for contraction is changed to a higher value while if TCM
摘要:
An actuator end cap is provided for an actuator having a housing and a cover connected together and defining a joint therebetween. The end cap has a skirt portion disposed in overlying relation to the joint to provide a fluid-tight seal for the joint. A breather hole is formed in the side of the cover and a semi-cylindrical groove is formed on the inner surface of the skirt of the end cap. One end of the groove is disposed in communication with the breather hole in the cover and the other end of the groove is in communication with a vent hole extending outwardly through the end cap.
