Patent JP-2644532-B2 (JP)
IPC: C13K11/00
Filed: 1988-06-02
Granted: 1997-08-25
Abstract: The invention relates to a method for the production of crystalline fructose. The method comprises the steps of adding ethanol to a concentrated fructose solution; evaporating the mixture to a degree of supersaturation of at least 1.02; and adding anhydrous fructose seed crystals; removing ethanol-water azeotrope at a reduced pressure while maintaining the solution at a substantially constant temperature ranging from 50 to 75 DEG C so as to crystallize fructose; and recovering crystallized fructose, e.g. by centrifugation.
Patent JP-2558396-B2 (JP)
IPC: A61K47/32
Filed: 1991-06-11
Granted: 1996-11-27
Abstract: A controlled release pharmaceutical preparation comprising a core containing a medicinal compound and a coating layer containing a water-repellent salt and a water-insoluble and slightly water-permeable acrylic polymer having trimethylammoniumethyl group. Said preparation releases a medicinal compound in a sigmoid type dissolution pattern irrespective of the PH of a dissolution medium.
Patent JP-H0818833-B2 (JP)
IPC: C01F17/235
Filed: 1988-06-29
Abstract: A process for obtaining a ceric oxide. More precisely, a process for increasing and stabilising the specific surface of a ceric oxide at high temperature. 
<??>The process of the invention, which consists in preparing a ceric oxide by calcining a ceric hydroxide, is characterised in that the ceric hydroxide is subjected to a solvothermal treatment before the calcination operation.
Patent JP-2874966-B2 (JP)
IPC: G02B30/27
Filed: 1990-06-22
Granted: 1999-03-24
Abstract: An autostereoscopic viewing device with a flat picture screen and a pattern of cylindrical lens portions for producing three dimensional image perceptions without the need for additional optical accessories. The viewing device provides the largest possible freedom of movement of the viewer, whereby the reproduction quality is as uniform as possible and out of focus, cross-talk and other disadvantageous optical effect are greatly reduced. The procedures for making any necessary optical corrections are based on the plane parallel changeable positioning of a flat picture screen relative to an array of cylindrical lens portions. The array of cylindrical lens portions has an increasing thickness as well as a decreasing pitch width when moving from the middle to the vertical side edges. The pixel, or picture strip, size on the picture screen is a constant.
Patent JP-3469326-B2 (JP)
IPC: H03M1/66
Filed: 1994-08-16
Granted: 2003-11-25
Abstract: A digital-to-analog converter is provided which compensates for relative errors among weighting elements used for D/A conversion. The converter includes a decoder, a rotator, and a weighting section. The rotator receives decoded signals from a decoder to produce rotated output signals for activating or deactivating a plurality of weighting elements, respectively, included in the weighting section. The rotated output signals assure that the same number of weighting elements are activated in each of a plurality of sub-periods of time constituting a main period of time of the D/A conversion and that each of the plurality of weighting elements is activated the same number of times during the whole main period.
Patent JP-2640454-B2 (JP)
IPC: G06F9/38
Filed: 1986-08-28
Granted: 1997-08-13
Abstract: An instruction processor suitable for use in a reduced instruction-set computer employing an instruction pipeline which performs conditional branching in a single processor cycle. The processor treats a branch condition as a normal instruction operand rather than a special case within a separate condition code register. The condition bit and the branch target address determine which instruction is to be fetched, the branch not taking effect until the next-following instruction is executed. In this manner, no replacement of the instruction which physically follows the branch instruction in the pipeline need be made, and the branch occurs within the single cycle of the pipeline allocated to it. A simple circuit implements this delayed-branch method. A computer incorporating the processor readily executes special-handling techniques for calls on subroutines, interrupts and traps.
Patent JP-2606800-B2 (JP)
IPC: H03H9/02
Filed: 1987-08-27
Granted: 1997-05-07
Abstract: A surface-wave resonator filter having at least two reflector structures and at least one interdigital transducer. At least a portion of one of the reflector structures has interruptions in the metallization strips thereof to define subsections of the metallization strip. Connecting metallizations are provided parallel to the wave propagation direction x between neighboring sub-sections of neighboring sub-divided metallization strips to electrically connect the neighboring sub-sections such that no two sub-sections of the same sub-divided metallization strip are electrically connected.

Granted: 1996-08-07
Abstract: A keratinous fiber treating composition comprising the following components (a) and (b), and an acid. <CHEM>   The keratinous fiber treating composition according to the present invention makes it possible to impart a good elasticity to the hair without causing any damage (for example, dryness, stiffness and splitting) thereof.
