摘要:
A method and system for fluid characterization in an underground formation surrounding a borehole are provided. Acoustic signals are transmitted and received in the borehole. The received acoustic signals are processed to obtain at least one attribute of formation mobility. Formation fluid is characterized based on a change of the at least one attribute. A decision is made based on the characterization output.

The invention relates to a working vehicle which can improve a workability of a maintenance, inspection and the like with respect to a portion around an engine, and can tilt up a rear hood together with a tilt-up floor. An upper side of an engine (not shown) can be covered in a rear end portion side of a floor (35). A hinge mechanism (38) is arranged between a front end portion of the floor (35) and a rev-frame (25), and the floor (35) can be tilted up via the hinge mechanism (38). A rear hood (32) is coupled by hinge to a first support column (15) of a mounting bracket (4) supporting the floor (35), and is structured so as to be freely opened and closed. It is possible to tilt up the floor (35) in a state of attaching the rear hood (32), by canceling a fixed state of the mounting bracket (4) to a supporting and fixing member such as a counter weight (2) or the like.

In a laser exposure device according to the present invention, a positioning pin, which is formed in a lens holder supporting a lens system, is inserted through an elongated hole for restriction of a board holder supporting a laser diode. An eccentric cam is inserted into an elongated hole for rotation movement formed in a board holder and a circular hole for rotation movement which is formed in the lens holder and which faces the elongated hole for rotation movement. An eccentric cam is inserted into an elongated hole for slide movement formed in the board holder and a circular hole for slide movement which is formed in the lens holder and which faces the elongated hole for slide movement. The eccentric cams are rotated to relatively move the board holder and lens holder with respect to each other to thereby establish alignment between the optical axes of the laser diode and lens system. In a state where the eccentric cams are fitted into the elongated holes, the board holder and lens holder are fixed to each other by screws.
摘要:
A mark position detection apparatus has an illumination optical system for illuminating a measurement mark with illumination light and an imaging optical system for converging light reflected from the measurement mark to form an image of the measurement mark on an image pickup apparatus. The mark position detection apparatus measures a positional displacement of the measurement mark by processing an image signal obtained by the image pickup apparatus. The mark position detection apparatus has an optical element provided in the illumination optical system for compensating a difference in asymmetry of the image signal that depends on the wavelength of the illumination light.

An overlay measurement apparatus can judge whether an overlay displacement found from an image is accurate. It has a first measuring unit that captures images of first and second marks formed in different layers of a substrate and finds an overlay displacement between the two marks based on the images formed with light with a measurement wavelength range, a second measuring unit that captures the images of the two marks formed with light with an evaluation wavelength range different from the measurement wavelength range and finds the overlay displacement between the marks based on the images formed with the light with the evaluation wavelength range, and a calculation unit that calculates an index for accuracy of the overlay displacement in the measurement wavelength range based on the overlay displacements in the measurement and evaluation wavelength ranges found by the first and second measuring unit.
