    摘要： Provided is a technology of carrying out activation annealing of n type impurity ions implanted for the formation of a field stop layer (n+ type semiconductor region) and activation annealing of p type impurity ions implanted for the formation of a collector region (p+ type semiconductor region) in separate steps to adjust an activation ratio of the n type impurity ions in the field stop layer to 60% or greater and an activation ratio of the p type impurity ions in the collector region to from 1 to 15%. This makes it possible to form an IGBT having a high breakdown voltage and high-speed switching characteristics. Moreover, use of a film stack made of nickel silicide, titanium, nickel and gold films for a collector electrode makes it possible to provide an ohmic contact with the collector region.

    摘要： A valve-actuator for a hydraulic valve includes a valve chamber, ports spaced mutually and opening into the chamber, a spool axially located in the chamber for opening and closing hydraulic connections between at least two of the ports as the spool moves axially in the chamber. An actuator includes a housing having mutually spaced surfaces, and a piezoelectric element located in the housing between the surfaces, the element expanding and contracting in response to an electric signal applied to the element. A temperature compensation and motion damping circuit comprising feedback resistors and a thermistor. The spool moves axially in the chamber in response to expansion and contraction of the element.

    摘要： A method of testing a friction component for a transmission that has first and second parts. The first part of the friction component is attached to a drive shaft and the second part is attached to a grounding element. The first part of the friction component is rotated until the drive shaft and the first part of the friction component rotate at a target sliding speed Vtarget. An actuation force is applied to the friction component at a time t0. Operation of the motor drive is continued to maintain the speed of rotation of the drive shaft at Vtarget until a predetermined level of engagement torque Tth is obtained. The motor torque is then reduced to a predetermined level Tm. The sliding speed of the drive shaft is then decreased and the test is terminated when the sliding speed falls to zero.
