  • Patent number: 6453117
    Abstract: An image from a camera is to be recorded and reversion is to be made to an image of an optional scene to reproduce an image of such scene. To this end, a CPU 20 converts image signals at a rate of 90 frames per second from a camera device 10 into parallel signals to output image signals of the usual rate of 30 frames per second. A video server 30 records the image signals from the CCU 20 on a RAID 32. If a pre-set scene is to be reproduced, the image signals are read out from the RAID 32 in the order of the original image signals to output the read-out image signals to outside.

  • Patent number: 6268333
    Abstract: A fragrance composition which contains 1,3-dimethoxy-5-methylbenzene in an amount of from 0.01 to 30% by weight as a fragrance modifier that provides a sedative effect. 1,3-Dimethoxy-5-methylbenzene used in the present invention can exhibit a sedative effect not only by itself but also when mixed with various formulations of jasmine, floral and the like types having stimulative effects. Also, since a single chemical is used as an active ingredient, the present invention is more effective than the sedative function of natural essential oil from a viewpoint of sedation. In addition, since 1,3-dimethoxy-5-methylbenzene itself has a mild scent, its sedative effect can be obtained without altering original fragrance of interest.

  • Patent number: 5965069
    Abstract: A method for making optical preforms of optical elements without residual stress or distortion is provided. In this method, an optical material is supplied between upper and lower molds. The upper mold has a plurality of recesses arranged in a predetermined pitch, and each recess corresponds to a first surface shape of the optical element. The lower mold has a plurality of recesses facing the recesses of the upper mold and each recess of the lower mold corresponds to a second surface shape of the optical element. The supplied optical material is pressed between the upper and lower molds to be a set of optical preforms. The set of optical preforms is processed by die punching or tool cutting to separate each optical preform from the set of optical preforms. Each optical preform is used for producing an optical element by further pressing. Alternatively, optical element can be formed directly by the press molding process.
