Abstract: The present invention relates to a heating apparatus for glass-sheet-forming, which prevents formation of a heater distortion in a portion of a glass sheet facing to a temperature-distributing heat shield.

Abstract: A method for bending a glass sheet is provided wherein the glass sheet is put on a bending surface of a frame unit to be preliminarily bent by gravity before the glass sheet is pressed by an upper mold and frame unit. The method is utilized for controlling the amount of preliminary bending so as to control deformation of the glass sheet caused by the preliminary bending and pressing occurs on the preliminary bent glass sheet by the upper mold and the frame unit.

Abstract: Shape inspection is carried out without preparing an inspection apparatus for each model of product. There is provided a shape inspection method comprising a first step of placing an object to be measured on an inspection stand for actual measurement, a second step of obtaining information of the surface shape of the object, a third step of calculating shape data of the object in a weightless state based on the information of the surface shape of the object, and a fourth step of recalculating the shape data of the object in a state that the object is placed on a predetermined inspection stand based on the shape data in the weightless state of the object, and judging the quality of the object based on the recalculated shape data of the object.

Abstract: A heated and softened glass sheet is put on a bending surface of a frame unit to be preliminarily bent by gravity before the glass sheet is pressed by an upper mold and the frame unit. There are steps for using a certain means for controlling an amount of preliminary bending to control deformation of the glass sheet caused by the preliminary bending; and pressing the preliminarily bent glass sheet by the upper mold and the frame unit.

Abstract: An image data processing apparatus includes a zero-value prediction compressor for compressing data by predicting a zero-value region of a high-layer from a low layer of a wavelet space and eliminating data in a space other than a meaningful space, a zero-value prediction expander for restoring data after wavelet transform from compressed data with the data in the space other than the meaningful space being eliminated, a subtracter for making a difference between sub-bands, and a differential accumulation buffer for accumulating the difference. In addition, a decoder is provided to have a zero-value prediction expander and a difference accumulation buffer. The decoder predicts a zero-value in a high frequency component to perform mask processing.

Abstract: A paper feeding device used for feeding stacked paper to an electrophotographic copying machine is provided with a lift for a stack of papers, which move the top sheet against a swingably supported feeding roller as the size of the stack decreases under use. Forwardly of the feeding roller in the direction of travel of the paper is a plate in frictional contact with the roller, the paper being thus fed forwardly to the copying machine through the nip between the roller and plate. This arrangement avoids the problem of a multifeed of the sheets. The feeding-out operation may be further improved by the provision of separating claws engaging the leading corners of the paper as it passes from the feeding roller. Raising of the lift is controlled by a detecting device actuated by position of the swingable support for the feeding roller.

Abstract: A composite information recording apparatus is proposed in which in addition to known equipment for improving the image from a copy board onto a light sensitive medium such as a drum through an optical system, and reproducing copies of said image from the drum, a secondary optical system is provided which may intercept the path of the known optical system and direct the image to a photoelectric converter; the image on the photoelectric converter may be processed for external transmission, for storing in a memory or for activation of a second recording apparatus such as an optical fiber tube for recording information on the drum. The optical fiber tube may also be actuated from external message sources.

Abstract: A method of eliminating black banding occurring along the boundary line of an exterior information signal image and a pictorial original image in the process of recording compound information includes control of the luminance intensity of a scanning reproducing device immediately prior to and/or immediately following external information transfer thereby onto the photosensitive receiving surface. Such control provides gradual, timed increase of the luminance intensity of the device immediately prior to normal activation thereof, and/or gradual, timed decrease of the luminance intensity of the device immediately following normal deactivation thereof, so as to predeterminately merge the compounded images and thereby eliminate the black banding phenomenon.
