The present invention provides a substrate cleaning method capable of removing particles from the entire surface of a substrate to be processed at a high removing efficiency. In the substrate cleaning method according to the present invention, a substrate to be processed W is immersed in a cleaning liquid in a cleaning tank 12. Then, ultrasonic waves are generated in the cleaning liquid contained in the cleaning tank 12, so that the substrate to be processed W is subjected to an ultrasonic cleaning process. While the substrate to be processed is being cleaned, a dissolved gas concentration of a gas dissolved in the cleaning liquid contained in the cleaning tank is changed.

A check detector for the neck and finish portion of glass bottles is disclosed. The check detectors comprises means for rotating glass bottles successively conveyed to a fixed position and a slide block which can change position freely in the width direction and vertical direction of the bottle. A plurality of light emitters for illuminating the neck and finish potion of the glass bottle are mounted to the slide block. The light by from the plurality of the light emitters is converged to the illuminated region from difference directions, and there are a plurality of light receivers equipped with light sensors for detecting the light reflected by checks in the neck and finish portion of the bottle, the light reflected by the mold seam formed at the neck and finish portions, and the directly transmitted light passing through the neck and finish portion, via lenses mounted to the slide block. There is a light emitter control section for constantly operating a plurality of light receivers in the light emitting condition so that the reflected and direct light are input as data, wherein each of the light receiving elements are divided so as to correspond to the vertical position of the neck and finish portion. The data inputted as light reflected at the seam and the data inputted as the direct light transmitted through the neck and finish portions are deleted.

A rotary actuator is disclosed which changes the angular position of the rotary valve which is used to determine the attenuation presented by a shock absorber. The rotary actuator is disposed within a cylindrical piston rod of the shock absorber, and comprises a power transmission mechanism for driving the rotary valve for rotation between a first and a second position within a given range, a d.c. motor for driving the mechanism, a first stop mechanism for selectively stopping the rotation of the motor at a third position which is situated centrally within the given range, and a solenoid assembly for making the first stop mechanism operative. These components are disposed within the cylindrical piston rod in the sequence named from below to above. The power transmission mechanism includes a second stop mechanism which prevents the rotary valve from rotating outside a first and a second location which determine the given range.

An electromagnetic control valve is provided with a housing having an inlet and two outlets extending through the wall of the housing. A valve member is mounted in spaced relation from each outlet opening on a resilient member for movement into and out of engagement with a valve seat surrounding the outlet opening. An elongated valve actuator is pivoted at its mid-point between the two valve members and is provided with a projection adjacent each end disposed in contact with a respective valve member. A spring normally biases the valve actuator about its pivot point to bias one of the valve members into engagement with its associated valve seat. An electromagnet is located on the opposite side of the valve actuator from said one of said valve members to pivot the valve actuator against the force of the spring.
