Filed: 2008-08-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide a vacuum carburizing method and a vacuum carburizing device which can sufficiently improve the hardness and toughness of a workpiece.  <P>SOLUTION: The vacuum carburizing method comprises: a temperature increasing stage where a workpiece in a heating chamber is increased to a prescribed temperature; a carburizing stage where, in a state where the temperature of the workpiece reaches the prescribed temperature, a gas for carburizing is fed into the heating chamber storing the workpiece from a state where the inside of the heating chamber is decompressed to an extra-low pressure atmosphere, thus the workpiece is carburized; a diffusing stage where, after the carburizing stage, the feed of the gas for carburizing is stopped, and carbon as an element composing the gas for carburizing is diffused from the surface of the workpiece to the inside; and a cooling stage where, after the diffusing stage, the workpiece is cooled. The method is characterized in that the carburizing stage and the diffusing stage are alternately repeated for a plurality of times.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Title: Method for modifying sugar chain structure in plant, and plant
Inventor: MATSUO YUKITAKE
IPC: A01H1/00
Filed: 2008-08-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for reducing or inhibiting the modification of an N-linked sugar chain with fucose in a plant, a transgenic plant in which the fucose modification is reduced or inhibited, and others.  <P>SOLUTION: The amount of GDP-fucose in a plant cell is reduced by inhibiting the transcription/translation of a gene encoding an enzyme involved in the synthesis of a sugar nucleotide GDP-fucose through posttranscriptional gene silencing (PTGS), virus-induced gene silencing (VIGS) or transcriptional gene silencing (TGS). In this manner, the modification of a sugar chain such as a glycoprotein sugar chain, a glycolipid sugar chain, an oligosaccharide or a polysaccharide with fucose is reduced or inhibited, thereby producing a glycoprotein or the like in which a fucose-modified part, which can act as an allergen, is removed. It becomes possible to use a medical glycoprotein produced in a plant for clinical purposes.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Title: Method and device for stabilizing polarization state, and optical signal processing system
Inventor: FUTAMI FUMIO
IPC: G02F1/01
Filed: 2008-09-01
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical communication technique for stabilizing polarization state of light to signal light used mainly for optical communication, for collectively stabilizing the polarization state of multiwavelength light regardless of the polarization fluctuating rate of light without needing a complicate electronic circuit or control circuit.  <P>SOLUTION: A polarized beam splitter 102 divides an input light into two mutually orthogonal polarized lights and guides the lights to different paths 1 and 2. A polarization rotation element 107 rotates the polarized light at about 90° on the path 2. An optical path length adjuster 106 adjusts the difference in optical path length between the paths 1 and 2 so as to be substantially zero. A liquid crystal light modulator 103 is, for example, a liquid crystal optical modulator which adjusts the difference in optical path length between the paths 1 and 2 so as to be substantially an integral multiple of the wavelength of the input light on the path 1. An optical attenuator 105 adjusts the propagation losses of the paths 1 and 2 to be substantially equal to each other on the path 2. A polarization independent beam combiner 108 couples and outputs the two polarized lights propagated in the paths 1 and 2 as an output light.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a pedestrian detecting apparatus for vehicle, capable of accurately deciding the start of movement of a pedestrian, from a standstill.  <P>SOLUTION: With regard to a pedestrian behavior (vehicle-path crossing action), by use of a knee portion movement velocity Vkt and a shoulder portion movement velocity Vst on which the pedestrian will is reflected, the conditional expression in the pedestrian movement start is defined by the form of the kinetic energy of the knee portion and the shoulder portion as: (Vst/α)<SP>2</SP>+(Vkt/α)<SP>2</SP>>1 (where Vst>0 and Vkt>0, α: normalized coefficient).
