    Abstract: A scanning optical apparatus comprises: a light source unit, optical system for converging a light beam from the light source unit at a predetermined position, moving device for moving the converged position of the light beam by the optical system; deflecting device for deflecting the light beam from the light source unit in a predetermined direction; light receiving device for receiving the light beam deflected by the deflecting device, processing device for processing a signal obtained by said light receiving device, and control device for controlling the moving device correspondingly to a signal from the processing device, the light beam emitted from said light source unit being scanned on said light receiving device a plurality of times through said optical system and said deflecting device while the converged position of the light beam is moved by the moving device, and the signal from the light receiving device during each of the plurality of times of scanning being compared or calculated by the processing device to thereby adjust and determine the converged position of the light beam by the optical system.

    Abstract: An image processing apparatus can be used by users physically-handicapped in the visual sense and users physically-handicapped both in the visual and auditory senses, as well as by normal users. In the apparatus, an image pickup device need not be pressed against the output picture surface of a visual display, resulting in an easy operation and easiness in other kinds of operations. The apparatus includes a first display output unit for displaying visual display information, a conversion device for converting the visual display information into auditory information or tactile information, and a second display output unit for displaying the converted auditory information or tactile information with a sound or vibration. The second display output unit performs a display operation in response to a switching operation of a second input device.

    Abstract: A scanning optical equipment provided with the means to detect scanning beam spot at more than two points of the scanned surface and the means to enable direct observation of the state of focussing of the beam spot, thus enabling extremely precise control of the state of focussing and forming an extremely high density image which could not be obtained by the conventional methods.

    Abstract: A method of exposing a wafer to exposure energy such as ultraviolet rays or X-rays through a mask to transfer a pattern of the mask onto the wafer, for example. The temperature of the mask and/or the wafer increases during the exposure operation by absorption of the exposure energy. During the wafer being exposed, the temperature of the mask and/or the wafer is detected. If the temperature is going to exceed the exposable temperature range determined on the basis of the line width of the pattern to be transferred, the exposure operation is interrupted. Then, the heat accumulated in the mask and/or the wafer is removed. Thereafter, the exposure operation is resumed. This is repeated until the predetermined or required amount of exposure is reached, for one shot. By this, the thermal expansion of the mask and the wafer during the exposure operation is prevented to assure the precision of the pattern transfer.

    Abstract: The mask(3) and the wafer (4) are closely disposed, and predetermined exposure energy is applied to the respective shot areas of the wafer(4) through the mask (3). The exposure energy is soft-X-ray source, for example. The pattern of the mask (3) is transferred onto the respective shot areas in a step-and-repeat manner. In the apparatus (fig 1), a temperature control medium liquid is supplied into the wafer chuck (5) for supporting the wafer (4) at the exposure position. The flow rate is different during the exposure operation than during the non-exposure-operation. The flow control (10) is determined in consideration of the wafer chuck vibration attributable to the supply of the liquid medium and also to the heat generation in the wafer(4) by the exposure energy, so that the vibration of the wafer chuck (5) during the exposure operation is suppressed, and simultaneously, the temperature rise of the wafer (4) can be also suppressed. The pattern transfer from the mask (3) to the wafer (4) can be precisely performed.
