In order to suppress quick potential change on the surface of a process target when the shutter plate is opened and closed, when an ion beam IB from the ion source 10 is irradiated on a substrate 38 and the ion beam IB is neutralized by using neutralizing electrons e− generated by a microwave neutralizer 14, the shutter plate 62 shields the substrate 38 before and after the milling processing of the substrate 38, and the voltage of a power supply 34 is lowered when the shutter plate 62 is opened and closed so as to limit the amount of ion beam IB irradiation, thereby suppressing charge-up on the surface of the substrate 38.

In measuring pattern with large process fluctuation, correct measurement cannot be carried out if noises, such as pattern that is not the subject to be measured, and dirt, are present in periphery of pattern to be measured in previously registered measurement region. Among the image data of sample, predetermined region aligned by pattern matching is set as region not to be measured that is excluded from subjects of pattern measurement. For example, in measuring pattern with large process fluctuation, only region including pattern with small process fluctuation is used in pattern matching, while in measuring the pattern, predetermined region, which was used in pattern matching and aligned, is set as region not to be measured. Stable pattern measurement can be easily carried out with respect to pattern with large process fluctuation, without being affected by region where measurement region and region not to be measured overlap with each other.
摘要:
A method and apparatus suitable for determining the concavity and convexity of line and space patterns formed on a sample. A profile is formed based on a charged-particle beam scan, the profile having a peak. When one foot portion of the peak converges more gradually than the other foot portion, a portion of the sample corresponding to the one foot portion is determined to be a convex portion. Alternatively, when one foot portion of the peak converges more steeply than the other foot portion, a portion of the sample corresponding to the one foot portion is determined to be a concave portion.

An X-Y table actuator is constituted by stacking a stationary plate, an intermediate plate, and a movable plate. Between the stationary plate and the intermediate plate, arranged is an X-direction drive means for driving the intermediate plate in an X-direction with respect to the stationary plate. Between the intermediate plate and the movable plate, on the other hand, there is provided a Y-direction drive means for moving the movable plate forward and backward in a Y-direction with respect to the intermediate plate. By stacking the stationary plate and the movable plate, which are formed into a substantially channel-shape, and the intermediate plate, which is formed into a substantially flat-shape on each other, a housing chamber for the X-direction drive means is formed between the stationary plate and the intermediate plate, and a housing chamber for the Y-direction drive means is formed between the intermediate plate and the movable plate.

A beach cleaner for recovering waste while moving in a towed state by a traction vehicle. A grating-like portion scoops up waste present in front of the beach cleaner as the beach cleaner is moved and a reticulate portion that is formed behind the grating-like portion to hold waste. As the beach cleaner is moved, waste present in front of the beach cleaner is scooped up onto the grating-like portion and is held with the reticulate portion formed behind the grating-like portion. Sand that is scooped up together with the waste is allowed to drop through the gaps in the grating-like portion.

A beach cleaner for recovering waste while traveling in a towed state by a traction vehicle. A grating-like portion scoops up waste present in front of the beach cleaner as the beach cleaner is moved. A rotor is disposed on an upper side of the grating-like portion and is adapted to rotate so that a lower portion thereof moves rearwardly. The rotor is mounted on a rotary shaft extending in the transverse direction of the beach cleaner. Waste is delivered rearwardly between the rotor and the grating-like portion. With travel of the beach cleaner, waste present in front of the beach cleaner is scooped up onto the grating-like portion and sand which is scooped up together with the waste is allowed to drop through gaps in the grating-like portion.

A beach cleaner for recovering waste while being towed by a traction vehicle. The beach cleaner includes a grating-like portion for scooping up waste present in front of the beach cleaner as the beach cleaner is moved. The grating-like portion is inclined so that the front side thereof assumes a lower position. A rotor is disposed on an upper side of the grating-like portion and for rotation so that a lower portion thereof moves rearwardly. The rotor is centered on a rotary shaft extending in the transverse direction of the vehicle. The rotor delivers the waste rearwardly between the rotor and the grating-like portion. A reticulate portion is formed behind the grating-like portion. The reticulate portion is inclined so that the rear side thereof is located at a lower position to hold waste. With movement of the beach cleaner, waste present in front of the beach cleaner is scooped up onto the grating-like portion and sand which is scooped up together with the waste is allowed to drop through gaps in the grating-like portion.
摘要:
A beach cleaner for traveling on sandy soil while being towed by a traction vehicle for recovering waste such as empty cans scattered on the sandy soil. The beach cleaner is provided with a travel body. The travel body includes a plurality of longitudinal members arranged in a hurdle shape spacedly and extending in a travel direction and also having in a front portion thereof a portion to be pulled by the traction vehicle. A flat plate-like scraper for scraping up waste together with sand during travel of the beach cleaner is provided in the front portion of the travel body. A net for separating waste from a mixture of sand and waste scraped up by the scraper and for storing the thus-separated waste thereon is stretched on an upper surface of the travel body.

An overtop position is to be established in a hydrostatic type continuously variable transmission, and an increase of the maximum speed and the maintenance of power performance are to be made compatible with each other. In a hydrostatic type continuously variable transmission, the angle of inclination of a movable swash plate is controlled in such a manner that a target Ne is calculated from both RC (riding condition) and throttle valve opening, then the target Ne thus calculated is compared with an actual Ne to determine a rotational direction and DUTY of a control motor. The operation of the control motor is controlled in accordance with the thus-determined data and angle information on the angle of the movable swash plate provided from an angle sensor. In constant speed vehicular traveling, the change gear ratio is set at TOP ratio and a shift is made to OVERTOP when predetermined overtop control conditions ((1) the current change gear ratio should be at TOP position, (2) the degree opening of a throttle valve should exceed a threshold value determined according to a vehicular speed, and (3) the engine speed should exceed a preset value) are satisfied, thereby increasing the maximum vehicle speed.
