20080230590 | METHOD FOR FABRICATING DISSIMILAR MATERIAL JOINTED BODY - A method for producing a bonded body of different materials of the present invention is a method for producing a bonded body of different materials ( | 09-25-2008 |
20090061040 | DIE FOR FORMING HONEYCOMB STRUCTURE - A plate-like shape die | 03-05-2009 |
20090230176 | JOINING JIG AND METHOD FOR MANUFACTURING A BONDED BODY OF DIFFERENT MEMBERS BY USING THE JIG - A joining jig | 09-17-2009 |
20090232927 | HONEYCOMB STRUCTURE-FORMING DIE AND METHOD FOR MANUFACTURING THE SAME - A honeycomb structure-forming die 1 has a die substrate 22 including a first plate-shaped member 23 having back holes 6 for introducing a raw forming material and a second plate-shaped member 24 having slits 5 for forming the material into a lattice shape. The first plate-shaped member 23 has columnar portions 8 where at least a part is zoned by a slit-shaped groove portion 7 corresponding with a shape of the slit 5 on a bonding face side 28 where the first plate-shaped member 23 is bonded with the second plate-shaped member 24. In the columnar portions 8, the ratio (L/T) of the height L of the columnar portions 8 to the minimum width T in an end face on the bonding face side 28 is within 1/3 to 3.5. Thus constituted die realizes high formability, and two plate-shaped members constituting the die substrate are hardly peeled from each other. | 09-17-2009 |

20130248159 | HEAT CONDUCTION MEMBER - A heat conduction member includes: a cylindrical ceramic body, a metal pipe on the outer periphery side of the cylindrical ceramic body, and an intermediate member held between the cylindrical ceramic body and the metal pipe. The cylindrical ceramic body has passages passing through from one end face to the other end face and allowing the first fluid to flow therethrough. The intermediate member is made of material having at least a part having a Young's modulus of 150 Gpa or less. The first fluid is allowed to flow through the inside of the cylindrical ceramic body while the second fluid having lower temperature than that of the first fluid is allowed to flow on the outer peripheral face side of the metal pipe to perform heat exchange between the first fluid and the second fluid. | 09-26-2013 |
20140017509 | BONDED OBJECT OF TUNGSTEN CARBIDE-BASED SUPERHARD ALLOY AND PROCESS FOR PRODUCING SAME - Provided in the present invention is a bonded tungsten carbide-based super hard alloy assembly equipped with a first metal member having a first bonding surface and comprised of a steel material containing a martensite structure and a second metal member having a second bonding surface directly bonded to the first bonding surface of the first metal member and comprised of a tungsten carbide-based super hard alloy. The martensite structure-containing steel material which constitutes the first metal member is a stainless steel having an average carbon concentration of from 0.10 to 0.40 mass %. The first metal member has a high carbon concentration region at a depth ranging from 0.70 to 3.00 mm from the first bonding surface. The high carbon concentration region has a maximum carbon concentration of from 0.3 to 1.2 mass %. The bonded tungsten carbide-based super hard alloy assembly has both high bonding strength and excellent mechanical strength. | 01-16-2014 |
20140090821 | HEAT EXCHANGER ELEMENT, MANUFACTURING METHOD THEREFOR, AND HEAT EXCHANGER - A heat exchanger element includes at least two honeycomb structures arranged serially and each including a cell structural portion having cells separated and formed by partition walls containing SiC and functioning as passages which extend from one end face to the other end face and which a first fluid passes through, and an outer peripheral wall disposed on the outer periphery of the cell structural portion. The first fluid passes through the cells of the honeycomb structures without leaking out of the cells or mixing. The cell structural portions of at least a pair of the honeycomb structures adjacent to each other among the honeycomb structures arranged serially are disposed with a gap, and the first fluid passing through the cells mixes together between end faces forming the gap. | 04-03-2014 |
20140102683 | HEAT EXCHANGE MEMBER - There is provided a heat exchange member which does not easily suffer from breakage due to thermal stress by relaxing the thermal stress. The heat exchange member is provided with a honeycomb structure ( | 04-17-2014 |
