    Abstract: A method of measuring the diameter of an electron beam in which the electron beam diameter is measured from the leading edge or trailing edge of a detector signal that is obtained as the mark area formed on the specimen is scanned by the electron beam. This method comprises the following steps: scanning the specimen by the electron beam at least once to find the maximum and minimum values of the detector signal; setting two threshold levels based on the maximum and minimum values; scanning the mark area by the electron beam to measure the time interval during which the level of the detector signal is within the two threshold levels; and calculating the beam diameter.

    Abstract: A pump characteristics expression of a pump is developed based on a closed-state pressure detected when the pump is driven while a space between a pump passage and a first passage is closed, an open-time pressure detected immediately after the space is opened while the pump is operated, and a flow rate characteristics expression of the pump passage. A reference pressure is determined by an intersection point between the pump characteristics expression of the pump and a flow rate characteristics expression of an orifice having a predetermined passage area. A leak check portion determines whether a leak of fuel evaporation generated from a fuel tank is within an allowable range by comparing the reference pressure and a pressure detected when the pump is operated for a predetermined period while the space is opened.

    Abstract: Stable receiving action is achieved with a receiver of simpler configuration.When a human hand is held over the panel unit 201, the electric field in the vicinity of the human body is coupled to the sensor electrode 2122 of the coil sensor 212 from the receiving electrode 211 of the panel unit 201, and alternate current is generated at the sensor electrode 2122. This alternate current then induces a magnetic flux inside the central opening of the coil 2121 in proportion to the strength of the electric field in the vicinity of the human body. Depending on the changes in this magnetic flux, electric current passes through the coil 2121. The electric current passing through the coil 2121 is converted by the electric current detecting circuit 2124 of the coil sensor 212 to voltage signals and transmitted as received signals to the demodulator 22. As a result, the received signals corresponding to the electric field in the vicinity of the human body, namely the transmission signals applied by the transmitter 1 to the human body, are obtained.
