A normal motion of the object represented by the video signal is detected on the basis of the detected correlation. Scanning lines represented by the video signal are interpolated with changeable interpolation characteristics. The interpolation characteristics are changed in response to the detected normal motion of the object.

Abstract: A novel glycoside, 4 G -alpha-D-glucopyranosyl rutin, is formed by a saccharide-transferring enzyme and glucoamylase in a solution which contains rutin together with glucoamylase. The 4 G -alpha-D-glucopyranosyl rutin formed in such a solution is purified with a synthetic macroreticular resin, and crystal­lization in an organic solvent yields a complex crystal with the organic solvent. 4 G -alpha-D-glucopyranosyl rutin exhibits the same molecular absorption coefficient as intact rutin has, and is readily water-soluble, substantially tasteless and odorless, and readily hydrolyzable  in vivo  to exhibit physio­logical activities inherent to rutin. These render 4 G -alpha-­D-glucopyranosyl rutin very useful as a highly-safe, natural yellow coloring agent, antioxidant, stabilizer, quality-im­proving agent, preventive, remedy, uv-absorbent and deterio­ration-preventing agent in foods, beverages, tobaccos, cigarets, feeds, pet foods, pharmaceuticals, cosmetics and plastics.

Abstract: Disclosed is a unique vehicle system which provides a desir­able rheology to products formulated therewith, enhanced disper­sion of actives therein, and improved deposition of actives therefrom. This vehicle system comprises a primary thickening agent which is a nonionic long-chain alkylated water-soluble polymer, and a secondary thickening agent which is a water-soluble surfactant, dispersed in a compatible solvent. Optionally, a rheological aid, which is a chelating agent may be included in the vehicle system. Also, optionally, a distributing aid, which is a water-soluble polymer of either high molecular weight or strong ionic character may be included in the vehicle system. These vehicle systems are useful in cosmetic compositions which are used to deliver an active component to the hair or skin. The vehicle systems are particularly useful in hair care compositions, espe­cially rinse-off hair conditioning compositions, because they effectively deliver the hair conditioning component to the hair without depositing a substantial amount of the vehicle material onto the hair.

Abstract: A charge coupled device imager has an imaging section comprising a plurality of photoelectric converting sections and a plurality of horizontal charge transfer sections. Each of the photoelectric converting section is surrounded with a channel stop region for isolating each other and a readout gate region.

Abstract: The invention relates to a method for determining the level of corrosion of metal parts, in particular of cavities in said parts. The object is to improve such a method so as to make it possible to assess the level of corrosion of metal parts rapidly and reliably without said parts having to be optically accessible. The object is achieved in that the metal parts are exposed to an atmosphere isolated from the environment and consisting of an inert carrier gas with a reactive gas added which enters into a chemical and/or physical reaction only with the corrosion products formed on the surfaces of the metal parts, and in that the difference between the amount of reactive gas fed to the metal parts and the amount drawn off again from the metal parts is determined. <IMAGE>

Title: Magnetic tape drive with integral multiple-cassette removable magazine
Inventor: PIERRAT MICHEL A
IPC: G11B15/68
Filed: 1991-07-08
Abstract: © A number of data storage cassettes are held in a removeable magazine that forms part of a tape drive by which the magnetic tapes are recorded or played. The magazine holds two parallel vertically-displaced decks of cassettes that are moved under positive driving force along a rectangular pathway formed by the two decks. From a pick-up position in the magazine, a cassette is automatically extracted by a robotic arm and placed in the tape platform for reading or writing by a conventional tape drive mechanism. When the use of the cassette is finished and it is ejected by the tape drive, a sensor activates the robotic arm to return the cassette to the pick-up position. Each deck has one unoccupied cassette space. If during the sequence of operations, the cassettes on the lower deck are moved by the width of one cassette in one direction, the cassettes on the upper deck are moved the same distance in the opposite direction. This movement results in a vacant position at the end of the upper deck farthest away from the pick-up position. The cassette in the pick-up position is either removed and loaded into the tape deck or the cycle is continued. Movement of the cassettes is produced by reciprocating drivers along the sides of the magazines. The casettes are moved in only one direction by the reciprocating drivers and are locked to prevent movement in the opposite direction. Motions of the cassette handling mechanisms are limited by mechanical stops that trigger an electronic circuit to interrupt the driving power eliminating the need for sensitive position switches. Slip clutches prevent mechanical damage from the mechanical stops. The removable magazine does not include any electric motor drives and is automatically disengaged from the cassette driving mechanism by its removal, thus permitting economical use of multiple magazines.

All of the individual leads (16) are angled so as to rotate in the same direction around the integrated circuit (10). This angled lead design provides enhanced strain relief and improved performance during use since the integrated circuit (10) is free to rotate under an applied stress, whilst efficiently maximizing the number of available electrical leads (16) for bonding to the integrated circuit chip (10). In addition, this electrical interconnection is suitable for use with tape automated bonding methods.
