Filed: 1990-12-17
Abstract: ABSTRACT An excipient, and in particular, a binder, useful in the manufacture of tablets, pellets, capsules, or granules for the delivery of active agents, is prepared by the enzymatic debranching of starch with an alpha-1,6-D-glucanohydrolase to yield at least 20%, by weight, short chain amylose.  A process for preparing short chain amylose from the debranched starch is provided.  The starch may be fully or partially debranched and may further comprise amylopectin, partially debranched amylopectin, long chain amylose, or a combination thereof, and may be modified by derivatization, crosslinking, dextrinization or conversion.  This starch is useful in the manufacture of tablets by direct compression or other tabletting methods.

IPC: C23G1/24
Filed: 1991-04-18
Abstract: A descaling method for removing oxide scale from a hot-rolled stainless steel comprising the steps of: applying a solution of an alkaline earth metal chloride to the surface of the oxide scale layer formed on the hot-rolled stainless steel strip, and allowing the solution to penetrate into the oxide scale layer.  In a subsequent annealing, the solution is heated and dehydrated to become solid matter and the dehydrated matter is melted and diffused into the oxide scale layer to soften the oxide scale layer.  The oxide scale layer is then removed by a simple mechanical descaling by, for example, grinding brushes with or without a subsequent chemical descaling by a weak acid solution.

Title: Ptc device
Inventor: YAMAZAKI NAOKI
IPC: H01C1/14
Filed: 1991-04-18
Abstract: ABSTRACT OF THE DISCLOSURE     A self-recovery PTC device for overcurrent protection of electrical circuits is made with a polymer/metal powder composition electrode that displays stable resistivity over a broad range of contact forces. Secure bonding of electrodes to a PTC element is achieved because both components are polymer composites, eliminating the problems associated with attempts to bond metal electrodes to a polymer PI C element. Swelling of metal electrodes, that results from outgassing by a PTC element, is also eliminated, because polymer electrodes are gas permeable.

Title: Integrated circuit for processing digital signals in video camera havingelectronic zooming function
Inventor: KAWAKAMI KIYOTADA
IPC: H04N5/262
Filed: 1991-10-31
Abstract: An output from a solid state image sensing device spatially modulated by a color filter is A/D converted and stored in a field memory. Digital signals read from the field memory during electronic zooming are successively delayed by 1H period by means of first, second and third 1H delay elements connected in series. The output from the field memory and outputs from the first, second and third 1H delay elements are separated into luminance components and line sequential color components by first to fourth Y/C separating circuits, respectively. A first set of three primary color signals are calculated based on outputs from the first, second and third Y/C separating circuits, and a second set of three primary color signals are calculated based on outputs from the second, third and fourth Y/C separating circuits. Three primary color signals corresponding to a new display point formed along with the execution of electronic zooming function are formed based on the calculated two sets of three primary color signals, and a luminance signal corresponding to the new display point is formed based on outputs from the first and second delay elements.

Abstract: ABSTRACT           A   drive   mechanism   is   provided   for mechanically driven doors of the type such as garage doors which are driven by a motor and guided at sides  thereof  by  guiderails  mounted  to  a  frame defining a door opening and which must be pivoted at least  slightly  before  being  vertically  raised, wherein  the  motor  drives  a  drive  means  which displaces vertically next to a side of the door. The  drive  mechanism  comprises  a  pick-up  means including an arm means connected to the drive means for vertical displacement therewith and a bracket means  mounted  to  the  door.   The  bracket  means includes an inclined portion extending upwards and away from the door.  The arm means includes a lost-motion means  which  is  adapted to  engage  a pivot means  connected to  the  door  and forming  a pivot therefor   The  arm means  includes  a drive member abutting a lower part of the inclined portion of the bracket  means  when  the  door  is  in  its  closed position and adapted to move upwards when the door is opened.   Therefore,  actuation of the motor to open the door causes an upwards displacement of the arm means and thus of the drive member which moves upwards along the inclined portion for causing the door to pivot about its pivot means with the lost-motion means of the arm means preventing the pivot means of the door from raising with the arm means, wherein after an initial upwards displacement of the arm means corresponding to the lost-motion means, the arm means drives upwards the pivot means  and thus the door which has an oblique orientation.

Abstract: A data recording method by which data of a compact disk can be recorded well onto a magneto-optic disk of the ISO format. Data of a compact disk are recorded onto a 5-inch magneto-optic disk (ISO format) of the 512 bytes/sector type of the CS system. The sector size of the magneto-optic disk is 610 bytes.      Data included in one sector (98 frames) of the compact disk are 2.352 bytes and subcodings of P to W are 96 bytes. Data for one sector are divided into data groups A to H to construct a data format. A CRC is added to each data group. Further, a parity 2 (Reed-Solomon node) is added. Data (3,050 bytes) for one sector of the compact disk to which the CRCs, parities and so forth are added are recorded across 5 sectors of the magneto-optic disk. Data of a compact disk can be recorded onto a magneto-optic disk having a different sector size. and since error correction codes or error detection codes are added using the remaining area, the data can be recorded with a high degree of accuracy.
