  • Patent number: 9964111
    Abstract: A motor-driven compressor includes an electric motor driven by a motor driver, which includes a switching element that converts DC voltage from a battery to AC voltage. A control unit controls the switching operation of the switching element. A temperature detector detects the temperature of the switching element. The control unit suspends the switching operation of the switching element when the temperature detected by the temperature detector rises to a temperature threshold. The temperature threshold includes a first temperature threshold, corresponding to a withstand temperature of the switching element, and a second temperature threshold, which is higher than the first temperature threshold. The control unit switches the temperature threshold from the first temperature threshold to the second temperature threshold when the control unit activates a field weakening control that reduces counter electromotive force generated by the electric motor.

  • Patent number: 9937548
    Abstract: A joint is produced in at least two overlapping workpieces using a joining tool including a punch reciprocally disposed in a cylinder. The workpieces are disposed between the tool and a die. The tool applies a compressive force to deform the workpieces into a joint at a joining area between the tool and die. Continuous ultrasonic energy is applied to at least one of the workpieces in the joining area for at least part of the time during production of the joint to increase the ductility of at least one of the workpieces in the joining area. This induces an acousto-plastic effect in the material being formed which temporarily reduces its strength so as to exhibit increased ductility. The joining method may be used in self-piercing riveting and clinching techniques and enables viable joints to be formed in high strength materials or thick sheets of material.

  • Patent number: 9863412
    Abstract: Dual cylinder and single cylinder rocking piston compressors with sound attenuation are disclosed. Due to the tapered shape of the intake and exhaust chamber sides and tops, the gas flow is accelerated and decelerated through the compressors thereby allowing sound energy to be dissipated. Sound attenuation is further enhanced by the addition of baffles, which divide each chamber into a series of smaller attenuation chambers. The baffles also cause the gas flow to accelerate and decelerate as the gas flow passes the baffles. In the case of a dual cylinder rocking piston compressor, enlarging the crossover passageway diameters also creates additional sound attenuation chambers, which contribute to the overall reduction in sound. Further, by using dedicated seals for each intake in the exhaust chamber, flow leakage at higher pressures is decreased, thereby improving compressor efficiencies.
