  • Patent number: 10608223
    Abstract: A method for manufacturing a separator for fuel cell including a seal part of thermosetting resin can have improved productivity. The method includes a placing step to place uncured thermosetting resin on a substrate, a pre-curing step to pre-cure the uncured thermosetting resin on the substrate, and a curing step to cure the pre-cured thermosetting resin on the collected plurality of substrates to collectively form the seal parts on the plurality of substrates.

  • Patent number: 10570497
    Abstract: There is provided a surface treatment method in which a processing gas is brought in contact with a heated processing object made of steel, an element in the processing gas is solid-solutionized, and thus a surface treatment is performed on the processing object. The processing object is heated to a heating temperature in a vicinity of a processing temperature at which the surface treatment is performed by heating an atmosphere in which the processing object is disposed. The surface treatment is performed by bringing the processing gas in contact with a surface of the processing object while the processing object which is heated is directly heated to the processing temperature.

  • Patent number: 10519536
    Abstract: A method of producing a carburizing forging material includes heating a steel material at 1300° C. or higher, forming Nb in a solid solution state and then rolling the steel material, heating the rolled steel material in a range of 950 to 1050° C., hot forging the heated steel material in a range of 950 to 1040° C., precipitating a Nb carbonitride in the steel material by cooling the steel material or maintaining a temperature of the steel material under a condition in which a time spent in a range of 950 to 970° C. is 1 minute or longer, precipitating a ferrite phase in the steel material by cooling the steel material or maintaining a temperature of the steel material under a condition in which a time spent in a range of 730 to 870° C. is 10 minutes or longer, and cooling the steel material to room temperature.

  • Patent number: 8986619
    Abstract: Disclosed is an exhaust air purification device, which enables heating a carrier uniformly and heating a catalyst supported on the carrier above an active temperature thereof even when an engine is run on a cold-start mode. Specifically disclosed is an exhaust air purification device, which includes a hollow case as an exterior, a cylindrical carrier housed in the case and having a catalyst supported thereon, and a pair of electrodes arranged on the outer circumferential surface of the carrier. In the device, the carrier is electrically heated through the pair of electrodes so that the catalyst is heated to an active temperature thereof. In the device, each of the pair of electrodes is placed on an arc-shaped outer circumferential segment of the carrier that has a central angle of 20 to 40 degrees, and the electrodes are opposed to each other with the phase difference of 180 degrees.

  • Patent number: 8866046
    Abstract: Provided is a technique in which blanks in different shapes are uniformly healed using energization healing. An energization heating process (S1) is a method for heating a blank (1) by connecting a pair of electrodes (10, 10) to two different end parts of the blank (1) so as to energize the electrode pair (10, 10), wherein the blank (1) is provided with void parts (cutouts (4, 4), a hole (5)) provided in a direction approximately perpendicular to the equipotential line generated between the electrode pair (10, 10), and current passages (current paths (20, 20)) are arranged in the direction approximately perpendicular to the equipotential line generated between the electrode pair (10, 10) within the regions spaced by the void parts (4, 4, 5) in the blank (1).
