Abstract: An electron beam detection device (34) is arranged on an electron beam passing path so that a beam delay time tB from a passing moment of an electron beam (1) to a moment when the beam reaches a predicted collision point (9a) is longer than a laser delay time tL from a moment when a command for generating laser light (3) is issued to the moment when the laser light reaches the predicted collision point (9a) by at least a predetermined delay time ?t. The device (34) may detect passing therethrough without affecting the electron beam and output a laser light generation command from a laser light command delay circuit (36) when the predetermined delay time ?t (=tB?tL) has elapsed after the detection.

Abstract: The measuring system includes a receiver including at least one fixed receiving antenna for picking up electromagnetic fields generated by a transmitting antenna belonging to an electronic device, and a positioning device on which a support element is placed. The positioning device includes mechanisms for driving the support element in rotation. The measuring system further includes a detection device for detecting position/orientation of the transmitting antenna, and a data processing station. A hollow spherical element houses the electronic device, and is held on the positioning device by gravity on three points, one of which is formed by a drive member, and the two other points are formed using ball and socket joints. Several circular barcodes arranged on the external surface of the spherical element enable the system to determine the position/orientation of the spherical element using the digital camera.

Abstract: The invention provides a valve and a method of operating the valve that makes it possible to reduce the diameter of the vacuum exhaustion pipings to make the facility for the vacuum exhaustion system small, which results in lower costs and shortens vacuum exhaustion time, and also which can prevent corrosion, cloggings, and seal leakages inside the piping system caused by the accumulation of substances produced by the decomposition of gas flowing through the pipings. In particular, in accordance with the present invention, an aluminum passivation is applied on the piping parts, i.e. the valve and others, that are used in the vacuum exhaustion system so as to inhibit gas decomposition caused by temperature rise at the time of baking so that components for reduction in the diameter size in the vacuum exhaustion system are provided. Thus, corrosion, cloggings and seat leakages caused by gas decomposition are prevented.
