Abstract: The generation of excessive electron radiation or X-ray radiation is prevented in an apparatus which comprises an accelerator means for generating and accelerating electrons. These electrons form an electron beam which has a predetermined low energy level for the generation of electron radiation or a predetermined high energy level for the generation of X-ray radiation. In case of generating electron radiation a scattering foil or a target, respectively are arranged in the trajectory of the electron beam. The foil and the target are movably arranged on a support means. Detecting means operable by this support means sense the position of the foil and the target relative to the trajectory of said electron beam and inhibiting means prevent the generation of an electron beam having an energy level which exceeds the predetermined low energy level if the target is not positioned and/or which exceeds the predetermined high energy level if the target is positioned in the trajectory of the electron beam.

Abstract: A high resolution shadow mask with low pattern distortion is formed from a silicon membrane with a pattern of apertures etched through the membrane by reactive ion etching using a silicon dioxide masking layer. To achieve low distortion over a large area membrane, the stress of the membrane and the masking layer is controlled to remain within an optimal range so that the stress relief that occurs when the apertures are formed is kept negligibly small. A silicon membrane with controlled stress is made using a p/n junction electrochemical etch-stop process. After making the membrane, it is then coated with a deposited silicon dioxide layer. The stress of the oxide layer may be adjusted to an optimum value by annealing after deposition. The membrane with the oxide mask layer is next coated with a photoresist layer which is then patterned with the desired shadow mask pattern. Once the photoresist is patterned, the pattern is then transferred into the oxide layer by reactive ion etching. The patterned oxide then serves as the mask for etching apertures through the silicon membrane, also done by reactive ion etching.

Abstract: The present invention relates to a color copying apparatus which prevents toner scattering from a tip portion of a cleaner to an image area of an image carrying drum. An exposing device forms a stripe latent image in a stripe area at an upstream of the image area of an image carrying drum in a rotating direction of the image carrying drum, and a developing device stops development within the stripe area. The result is a generation of a sharp potential gap in the stripe area. The cleaner starts cleaning by touching to the stripe area, and accumulated toner on the tip of the cleaner is attracted by the sharp potential gap and is held within the stripe area. This prevents the toner from being scattered to the image area of the image carrying drum.

Abstract: A random-access type storage device such as a hard disk or semiconductor memory is formatted to provide multiple partitions of varying block size. The data to be stored is in blocks of fixed size, and these blocks are compressed if the compressed size fits in the block size of a small-block partition in the storage device. If a data block is not compressible to the small block size, it is stored uncompressed in another of the partitions. The memory device also contains a table storing the locations of the blocks in the partitions, so upon recall the block is retrieved rom its location, decompressed (if it had been compressed), and sent to the CPU. For example, there may be two partitions, one using the block size of the original (uncompressed) data, and the other having a block size corresponding to the typical compressed size of the blocks of data (perhaps one-half the size of the original data blocks). The relative number of blocks in each partition (e.g., the physical storage capacity of each partition) is set at the average ratio of compressible blocks to uncompressible blocks for the compression algorithm used. For example, an algorithm may compress 90% of the blocks to 50% of their original size, so a ratio of the number of blocks in the compressed partition to the number of blocks in the uncompressed partition is selected as 90:10.

In this method, the object to the processed is placed in a furnace provided with heating means; the temperature within the furnace is elevated up to a predetermined level with the aid of an oxidizing gas atmosphere; the pressure in the furnace is reduced so that the quantity of the oxidizing gas is reduced to be below the explosion limit; and a reducing gas atmosphere is fed into the furnace to reduce the oxidization of the object to be processed. Thereafter, the interior of the furnace is evacuated while being maintained under a predetermined evaporation temperature condition; and the substance evaporated from the object to be processed is passed to recovery means provided in communication with the furnace, so that the substance thus evaporated is condensed in the recovery means and recovered therefrom.
