Abstract: The application methods in the related art cannot apply a sufficient voltage with a rectangular wave having a short rise time to an electronic circuit. Furthermore, electrostatic discharge test can apply a sufficient voltage but can only apply an oscillating waveform. A TLP generator is used as a rectangular wave generator. The sum of an injection resistance and a matching resistance is set so as to match the characteristic impedance of a transmission line for transmitting a rectangular wave to a test target. A capacitor is connected to a return line of the applied rectangular wave. With this configuration, stable application can be achieved. An error observation function of an electronic circuit gradually increases a peak value of the rectangular wave and determines the immunity based on an application voltage to cause an error for the first time.

Abstract: Disclosed is a simulator in which there are provided a field plate for electrostatically charging a device under test, which comprises a first substrate (high resistance substrate) having a relatively high resistance and a substrate having a predetermined dielectric constant; and a ground plate for discharging the charged device which comprises a relatively high resistance member and further comprises an additional ground plate.

Abstract: A power supply noise sensor includes a noise sensing section A to sense impulse noise applied to a power supply line and an output holding section B to hold a sense output from the noise sensing section A. The noise sensing section A includes a time constant circuit to gradually vary a power supply voltage including impulse noise. When a peak value of the impulse noise reduces after the peak value exceeds a predetermined value, a direction of a current flowing through the time constant circuit is inverted to hold a noise output from the output holding section B also after the impulse noise disappears. Therefore, the impulse noise in the forward direction and the impulse noise in the reverse direction superimposed onto the power supply system of the sensor can be sensed in a simple configuration.

Abstract: An apparatus and a method for checking that an electronic circuit device or an electronic circuit component such as an LSI operates normally or abnormally by applying an input pattern to the electronic circuit device or the electronic circuit component together with electromagnetic noises before comparing an obtained output pattern with an expected pattern so as to judge whether or not the patterns match in order to evaluate immunity to electromagnetic noises (conductive or radiation noises).

Abstract: An electromagnetic wave heater comprises an electromagnetic wave generator a wave guide being connected to the generator for guiding the generated electromagnetic wave to be propagated in a uniform direction, at least one container being provided in the wave guide for accommodating an object to be heated up by irradiation of the electromagnetic wave, the container having at least one tapered portion, a pointed end of which faces to a direction of the propagation of the electromagnetic wave in the wave guide.

Abstract: In a method of controlling travel of an automated guided vehicle, the automated guided vehicle is guided to travel along a guide marker arranged in a lattice form when the automated guided vehicle goes straight, and, when it turns, curve travel by autonomous control from a starting lattice point to a target lattice point.
