摘要： To evaluate cleanliness of wafer accommodating members used for storing or transporting of silicon, gallium arsenide or like semiconductor wafers, pure water is poured into a vessel-like wafer accommodating member, such as a wafer case body, a top cover, etc., capable of containing liquid therein, and then low frequency vibrations or supersonic wave is applied to the member. Alternatively, inner wafer accommodating members accommodated in the wafer case body, such as a wafer basket, a wafer retainer, etc., are accommodated in a vessel containing poured pure water, and the low frequency vibrations or supersonic wave is applied to the members. Then, the quantity of particles in the water is counted. Particles that have been attached to the wafer case or to inner wafer accommodating members accommodated therein, such as a wafer basket, a wafer retainer, etc., are made readily separable into the water, thus permitting quantitative detection of generation of particles from the inner wafer accommodating members.

The camera comprises: a picture size changeover device for selectively setting a photographing picture frame to a first picture size corresponding to the first film and a second picture size corresponding to the second film; a first lens installable and removable in and from the camera and having an image circle corresponding to the first picture size; a second lens installable and removable in and from the camera and having an image circle corresponding to the second picture size; and a device for judging which lens, the first lens or the second lens, to install in the camera. When the judging device judges that the first lens is installed in a state where the picture size is set to the second picture size, the picture size is so set as to be forcibly changed over to the first picture size.
