In a high frequency amplifying MOSFET having a drain offset region, the size is reduced and the on-resistance is decreased by providing conductor plugs 13 (P1) for leading out electrodes on a source region 10, a drain region 9 and leach-through layers 3 (4), to which a first layer wirings 11a, 11d (M1) are connected and, further, backing second layer wirings 12a to 12d are connected on the conductor plugs 13 (P1) to the first layer wirings 11s, 11d (M1).

In a semiconductor device including a power MOSFET (M.sub.0) for the output stage, a temperature detection circuit produces an output signal upon detecting an abnormal rise in the chip temperature, the signal turns on a set input element (M.sub.1) in a latch circuit so that the latch circuit becomes a set state, the set output of the latch circuit turns on a control element (M.sub.5), causing the power MOSFET to become non-conductive so that it is protected from destruction. The latch circuit is not brought to a reset state even if the external gate terminal of the device is brought to zero volt. With a voltage outside the range of the normal input signal, e.g., a large negative voltage, being applied to the external gate terminal, the gate capacitance of the control element (M.sub.5) discharges, and consequently the latch circuit is brought to the reset state and the protective operation is cancelled. The semiconductor device is further provided with an external reset terminal, and the protective operation can also be cancelled through the application of a reset signal to the external reset terminal. The semiconductor device is protected from destruction and also from deterioration of characteristics of the power MOSFET (M.sub.0), and yet the protective operation is not cancelled erroneously by the normal input signal.

In an ultrasonic inspection method or ultrasonic inspection system in which an ultrasonic wave is propagated to an test object via a medium such as a liquid or a gas, an incident position of the ultrasonic wave is accurately and reliably identified. In an ultrasonic inspection method based on an immersion technique, an optical irradiator is mounted on an ultrasonic wave transmitting/receiving unit, an optical marker is irradiated from the optical irradiator to the test object, and an irradiated position of the optical marker is imaged using imaging equipment in order to perform inspection.

The surface length of a metal subject to be inspected is evaluated by detecting an eddy current without using a combination of a scale and visual or liquid penetrant inspection. An exciting coil and a detecting coil are scanned above the subject in a length direction. An eddy current detector measures an output voltage corresponding to scanning positions based on an output from the detecting coil. Based on an output voltage distribution curve indicating a distribution of output voltages corresponding to the scanning positions, position information is extracted corresponding to values which are within a differential voltage range and lower by 12 dB than a maximum value of the output voltages on the left and right sides of the distribution. A distance between the positions included in the extracted information is calculated to evaluate the length of a slit which is a defect present on the subject surface.

An extended area uniform light source providing uniform luminance is taught for displays and other applications where the light emission can be planar or have curvature. The uniform light source is achieved using a combination of a blue light-emitting electroluminescent layer and a highly stable inorganic photoluminescent colour conversion layer to tailor the colour spectrum of the emitted light. The invention thus encompasses the uniform light source, displays incorporating the uniform light sources as well of methods of making such light sources and displays.
