    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: Ultrasonic flow rate measurement device includes measurement flow path in which a fluid to be measured flows, and a pair of ultrasonic vibrators that are disposed in directions such that a propagation path of an ultrasonic wave forms a V-shape relative to measurement flow path. Moreover, the device includes measurement circuit which measures a flow rate of the fluid to be measured by measuring a propagation time of the ultrasonic wave between the pair of ultrasonic vibrators, and inlet-side rectification part which is disposed, in the inlet side of measurement flow path, to stabilize the flow of the fluid to be measured. Furthermore, the device includes outlet-side coupling part which is disposed in the outlet side of measurement flow path, and signal lead-out part which outputs a flow rate value measured with measurement circuit.

    摘要: When a flow rate is equal to or more than a reference flow rate, a reference voltage is changed to a level capable of measuring stably to thereby realize the improvement of measurement accuracy at the time of a large amount of flow rate. A flow rate determination means compares a flow rate calculated by a flow rate calculation means with the reference flow rate. When the calculated flow rate is larger than the reference flow rate, the reference voltage set by a reference voltage setting means is changed, whereby the zero cross point can be detected stably at the portion where the degree of the influence of the change in the amplitude of the received signal is small. Thus, it is possible to provide a flow rate measuring device capable of measuring a flow rate stably with high accuracy even when a fluid flow is disturbed due to a large amount of flow rate.
