Abstract: Provided are a suspension bushing and a suspension device with which maneuvering stability can be improved without adversely affecting ride quality. Protrusions are formed on the outer circumferential surface of an inner tube, and slits are formed on the inner circumferential surface of an outer tube. The protrusions are arranged in the slits and have a tapered shape in which their width in a direction parallel to an axial line decreases as the distance from the axial line increases. The slits have a shape such that a gap in the direction parallel to the axial line decreases as the distance from the axial line increases.

Abstract: Provided are a suspension bush and a suspension device that are able to achieve both steering operability and stability of a vehicle at the time of turning. A projection portion is formed on the outer circumference of an inner cylinder. A guide is formed on the inner circumference of an outer cylinder. In the guide, a slit is formed along an extending direction that includes: a component, in a parallel direction, which runs parallel with an axial line; and a component in a circumferential direction around the axial line. The projection portion is disposed in the slit, and a threaded mechanism is formed by the projection portion and the slit.

Abstract: Upon starting the lasing device after having a stop state, gas retaining in the gas circulation path and the optical resonator is released through the gas release valve opened by the gas pressure controller. During a time calculated by the open-time calculator in response to the immediately preceding stop time of the lasing device, laser medium gas in the piping between the laser medium gas supply device and the gas supply valve is released, together with the retaining gas, through the gas supply valve opened by the gas pressure controller. The structure reduces costs by using decreased number of valves and suppresses consumption of laser medium gas.

Abstract: The gas laser oscillator apparatus of the present invention has a temperature-detecting mechanism disposed at the bearings of the bellows section. The temperature-detecting mechanism detects temperature rise in the bearings and calculates a maintenance cycle with reference to the predetermined data on relationship between temperature and the lifetime of the bearings. Disposed at the bearings, the temperature-detecting mechanism outputs a signal that indicates a replacement cycle according to the temperature of the bearings. More preferable, the temperature-detecting mechanism has a sensor at a tip end of a spring having a pressure force smaller than a load applied to the bearings in advance. To enhance accuracy of temperature detection, the spring is wrapped around with heat insulating material so as not to be exposed to outside temperature.

Abstract: Automatic pattern matching and shape measurement are enabled by adjusting a brightness level of a microscope image based on information of a local region of the image so that a magnified image of the local region takes on an appropriate brightness and is not affected by brighter peripheral portions of the image, thereby enabling feature extraction of a desired pattern. By using the inventive method in an energized beam apparatus having a sample stage capable of linear and tilting movement, a series of operations including cross section forming, sample tilting, cross section observation, and pattern recognition, may be performed on an automated basis.

Abstract: An orifice (254) is disposed near the junction of a discharge tube (1) and a laser gas lead-in pipe (242). A laser gas relay pipe (244) is disposed so as to allow the laser gas to flow parallel in the same direction as or in the reverse direction to the flowing direction of laser gas in the discharge tube (1). The orifice (254) includes a portion for impeding flow of laser gas, and plural holes for passing laser gas, and at least one of the holes is deviated from the center. The total area of the holes summing up the area of the plural holes provided in the orifice (254) is at a rate of 0.5 to 0.8 to the sectional area of the discharge tube. The plural holes of the orifice (254) are nearly circular, and the diameter of each hole is smaller than the radius of the orifice.

Abstract: The present invention provides a focused ion beam device that can automatically carry out pattern matching and shape measurement by adjusting brightness levels of microscope images on a display so that an observation region, becomes an appropriate brightness without being affected by brightness of peripheral images within the field of view, so as to be able to effectively carry out feature extraction of a noted pattern. Also, a system for supporting operations is constructed that does not require a series of operations to be executed in the presence of an operator each time in the event that fixed shape measurement is carried out.
