  • Patent number: 11851045
    Abstract: A series hybrid vehicle control method for controlling a vehicle that has a battery, an electric power generating motor, a drive motor and an internal combustion engine. The battery charged with the electric power from the electric power generating motor that generates electric power by being driven by the internal combustion engine, and charged with the electric power regenerated by regenerative braking of the drive motor. The drive motor drives a drive wheel. The electric power consumption for motoring is greater in a B range than in a D range. The control method sets deceleration caused by regenerative braking of the drive motor to be greater in the B range than in the D range, and starts motoring of the internal combustion engine in the B range at a lower SOC of the battery than the SOC of the battery in the D range.

  • Publication number: 20220355786
    Abstract: A series hybrid vehicle control method charges a battery with electric power generated by an electric power generation motor driven by an internal combustion engine, and electric power regenerated by a drive motor. The control method starts generating the electric power by the engine if a requested output exceeds a power generation start threshold value, and stops generating electric power by the engine if the requested output falls below a power generation stop threshold value. A deceleration rate by regeneration of the drive motor is greater in a second advancement shift position than in a first advancement shift position. The power generation start threshold value and/or the power generation stop threshold value where the second advancement shift position has been selected is greater than the power generation start threshold value or the power generation stop threshold value where the first advancement shift position has been selected.

  • Patent number: 9957063
    Abstract: According to one implementation, a structure for an aircraft includes a first structural member, a second structural member coupled to the first structural member, a fastener and a conductive object. The fastener couples the first structural member to the second structural member. The fastener is inserted into an insertion hole formed in a portion where the first structural member is overlapped with the second structural member. The fastener is in electrically non-contact with the first and second structural members in the insertion hole. The conductive object is embedded inside at least either one of the first and second structural members. The conductive object prevents a spark between the fastener and each of the first and second structural members by forming a current pathway that leads current, flowing inside the at least either one of the first and second structural members, to the other structural member.

  • Patent number: 9575097
    Abstract: Composite material sheets containing conductive fibers are laminated, and release films are interposed between the sheets so as to extend from one end to the center of the sheets. The sheets are heated under pressure to shape a composite material. Discrete conductive wires through which a measurement current is passed are connected to end surfaces of the respective layers in the composite material on the side on which the release films are interposed. A common conductive wire through which the measurement current is passed is connected to a surface of one of an uppermost layer and a lowermost layer at an end of the composite material opposite to the side on which the release films are interposed. A current is passed between the common conductive wire and the discrete conductive wires. Currents in the respective layers are sequentially or simultaneously measured using an ammeter.

  • Patent number: 6707528
    Abstract: An exposure apparatus is made so as to have respective chambers in which a main exposure system, a substrate carrying system, and a mask carrying system are housed. The apparatus is structured so that the respective environments in the chambers are substantially independently maintained from each other. Substrate processing can be facilitated by incorporating photoelectric detection of the substrate center in association with handing-over of the substrate from one substrate carrying member to another, and/or storage of a cleaning substrate in a storage member which also holds substrates being processed by the apparatus.

  • Patent number: 6698944
    Abstract: The exposure apparatus and the substrate processing unit is connected via an in-line I/F portion. In addition, information on the substrate carriage is communicated in between the control unit of the exposure apparatus side and the control unit of the substrate processing unit, and both units decide their next operation that contribute to improving the processing capacity related to the wafer carriage, before actually starting the operation. Therefore, the throughput of the series of wafer processing performed by the substrate processing unit and the exposure apparatus can be improved, and as a consequence, becomes possible to improve the productivity of the device. In this case, for example, information on the predicted time or the expected time when the substrate can be received or sent out is reciprocally communicated between both units.
