Abstract: The present invention allows assuring security of processing by the application itself without depending on the operating system. When a plurality of clients perform joint operation via a common server, the processing permitted for each server to perform to the server is predetermined, and when a user requests a processing which is not permitted, the client rejects this request. By this, the security among a plurality of clients can be assured without depending on the server.

Abstract: An optical semiconductor device includes an optical semiconductor element, a semiconductor region, and a buried layer. The optical semiconductor element is formed on a semiconductor substrate. The semiconductor region opposes the optical semiconductor element and essentially surrounds the optical semiconductor element to form walls. The buried layer is arranged between the walls of the semiconductor region and the optical semiconductor element and formed by vapor phase epitaxy. In this optical semiconductor device, a distance between the wall of the semiconductor region and a side wall of the optical semiconductor element is larger in a portion in which the growth rate of the vapor phase epitaxy in a horizontal direction from the side wall of the optical semiconductor element and the wall of the semiconductor region is higher.

Abstract: An image information compressing method for densely compressing image information, in particular, dynamic image information, a compressed image information recording medium for recording compressed image information, and a compressed image information reproducing apparatus capable of reproducing compressed image information at high speed in a short time are provided. Each image frame constituting a dynamic image information is divided into key frames and movement compensation frames. The key frame is divided into blocks so that an image pattern of each block is vector-quantized by using a algorithm of the Kohonen's self-organizing featured mapping. The movement compensation frame is processed such that a movement vector for each block is determined and a movement vector pattern constituting a large block is vector-quantized by using the algorithm of the Kohonen's self-organizing featured mapping.

Abstract: While a large number of positive and negative electrodes are alternately arranged in an alignment on a same level in an electrolytic tank, a pair of magnets having the polarities thereof fixed in the same direction and which are disposed along the direction horizontally orthogonal to the arrangement of the electrodes of the same level, so that an electric field and a magnetic field will be generated on the horizontal directions orthogonal to each other and a force according to the Fleming's left-hand rule will be directed to the upward direction perpendicular to both the electric field and the magnetic field. The small bubbles adherent to the surface of the electrodes are enabled to be separated therefrom and allowed to float up owing to the addition of the upward force to their insufficient buoyancy.

The compound is derived from the reaction of ribostamycin with crotonoyl chloride followed by concentration of the reaction product and by subsequent recovery therefrom of a fraction having a range of molecular weights of 10,000.about.100,000 when measured by ultrafiltration method.

Abstract: A new 1-N-(.omega.-aminoalkanesulfonyl) derivative of an aminoglycosidic antibiotic such as ribostamycin, 3'-deoxy- or 3',4'-dideoxy-ribostamycin, kanamycin A or B, and 3'-deoxy- or 3',4'-dideoxy-kanamycin B exhibits a broader, antibacterial spectrum than the parent aminoglycosidic antibiotic and is useful in the therapeutic treatment of infections caused by gram-positive and gram-negative bacteria including drug-resistant strains thereof. The aforesaid derivative may be made by reaction between the parent antibiotic and an amino-protected .omega.-aminoalkanesulfonic acid halide and removal of the amino-protecting group from the condensation product.
