Title: Gas sensor
Inventor: FUKUDA TAKANORI
IPC: G01N27/409
Filed: 2002-12-09
Abstract: <P>PROBLEM TO BE SOLVED: To provide a gas sensor capable of more suitably accelerating the flow of a gas around the detection element surrounded by a protective cover.  <P>SOLUTION: One end of a communication passage 15 is connected to the interior of an inside protective cover 21 and the other end thereof is connected to a catalyst converter on the downstream side thereof. Since the pressure in the exhaust pipe 13 on the downstream side of the catalyst converter is lower than the pressure (internal pressure P1) in the inside protective cover 21, the pressure in the inside protective cover 21 is reduced through the communication passage 15. Accordingly, an exhaust gas is guided to the periphery of the detection element 20 by making the internal pressure P1 lower than the peripheral pressure thereof to accelerate the low of the exhaust gas.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

IPC: H04N19/12
Filed: 2002-12-09
Abstract: <P>PROBLEM TO BE SOLVED: To reduce a generated amount of coded data without deteriorating image quality of an image area important in a visual sense.  <P>SOLUTION: An area division section 2 receives an input image signal 1. The input image signal 1 is divided into a plurality of areas by using an area shape of one preceding frame extracted from an external memory for an initial area shape. The area division section 2 divides the area again on the basis of the activity or the like of each area so as to apply integration processing to the areas by reducing the encoding cost between one area and areas in the vicinity thereof. An encoding section 7 encodes area shape information 3 or the like decided by the area division section 2 and converts it into a bit stream 11. The encoding section 7 outputs a locally decoded image 8 and writes it to an external memory 9. The locally decoded image 8 is used for a reference image 10 for the area division processing and the encoding processing. The external memory 9 writes also the area shape information 3. The area shape information 3 is used for the area division processing.  <P>COPYRIGHT: (C)2003,JPO

Filed: 2002-12-13
Abstract: <P>PROBLEM TO BE SOLVED: To provide an elastic pavement method for largely reducing cost by enhancing utilization efficiency of an elastic chip material of a waste material (removed urethane pavement or a waste tire).  <P>SOLUTION: This method elastically paves a stadium, a ground, a traveling road or a walking road. First of all, a curing resin material applying layer 14 of only a curing resin material is laid and leveled in the prescribed thickness smaller than the thickness of the whole pavement on a paving surface 11. The elastic chip material 13 is a little excessively sprayed and laid-leveled before curing the curing resin material applying layer 14, and an unstuck excess elastic chip material is recovered by a recovering machine except for the elastic chip material embedded and stuck in the curing resin material applying layer 14. A series of this paving process is repeated on a surface of the curing resin material and an elastic chip-containing layer 15, and is repeated in this way up to becoming the thickness of the whole pavement. This spraying type elastic pavement can enhance a mixing rate of the elastic chip material 13 more than a conventional kneading type by a mixer, and can improve utilization efficiency of the waste material.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Filed: 2002-12-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide a security system, a security method, and a security program when enciphering file data and writing it in a storage device.  <P>SOLUTION: Classification of a file write request is discriminated. In the case of a cache write request to a discrimination result, the file write request is immediately bypassed to a lower layer. When the cache write request is finished, a file input/output request is taken back, and then cache data are flashed. Hereby, delay write of a computer system is induced, and the file data are enciphered and written in a storage device. When the file write request is not a cache write request, the request is a write request in the storage device. In this case, the file data are enciphered, and the file input/output request is bypassed to the lower layer, and thereby the enciphered file data are written in the storage device.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
