摘要： An antenna device includes subarray antennas including antenna elements and feeding interfaces. Each feeding interface is connected to each of subarray antennas. The subarray antennas are arranged parallel to each other with an interval on a plane to be symmetrical about a central axis. The interval is less or equal than a free-space wavelength. The central axis is along with the center of two adjacent subarray antennas arranged at middle of the subarray antennas when the number of the subarray antennas is even. Moreover, the central axis is along with one subarray antenna arranged at the middle of the subarray antennas when the number of the subarray antennas is odd.

摘要： An antenna apparatus is constituted by first, second, third, and fourth wire antenna elements and a connection element. The sum of the lengths of the first, second, and fourth wire antenna elements is ¼ the wavelength corresponding to a series-resonance frequency of the first, second, and fourth wire antenna elements. The sum of the lengths of the second, third, and fourth wire antenna elements is ½ the wavelength corresponding to a parallel-resonance frequency of the second, third, and fourth wire antenna elements. The sum of the lengths of the first and third wire antenna elements is ¼ the wavelength corresponding to a series-resonance frequency of the first and third wire antenna elements. The parallel-resonance frequency is higher than the series-resonance frequency of the first, second, and fourth wire antenna elements and lower than the series-resonance frequency of the first and third wire antenna elements.

摘要： A grommet which is easy to install in a grommet hole of an automobile panel and has good water sealing ability. The grommet is assembled from a pair of grommet halves 21a and 21b, which include a pair of plastic leading members 1a and 1b, respectively, to form a leading section of the grommet; a pair of semi-disc plastic members 6a and 6b, respectively, to form an disc section of the grommet; and a pair of resilient members 12a and 12b, respectively, joining the members 1a and 1b with the semi-disc members 6a and 6b, respectively, to form a resilient section of the grommet. The resilient member shave semi-circumferential grooves 15a and 15b, which together form a complete circumferential groove 15 for receiving the edge of the panel defining the grommet hole when the grommet halves are coupled together. The disc section has a diameter larger than that of the leading section and the resilient section. The grommet halves are coupled together after wiring harnesses are placed therein, and locked by a locking mechanism provided on the outer surface of the grommet.

摘要： A method for measuring the flow rate of fluid such as liquified petroleum gas fuel for an automobile fuel. A signal of the fluid flow rate and a signal of the fluid temperature are produced by using the signals from an electric heater and a first, second, and third temperature-dependent resistors in a signal processing circuit. The produced signals are supplied to a computer circuit to carry out modification, linearization, and multiplication by a conversion constant for linearization which is corrected regarding temperature characteristic. The result of calculation in the computer circuit is displayed on a display device.

The DUT board holds a first antenna to be measured with radiation property and a probe to detect a signal from the first antenna. A part of the DUT board is inserted into the anechoic chamber through the aperture opened in the first wall. One end of the feeding arm holds a second antenna radiating a radio wave to the first antenna in the anechoic chamber. Each rotation unit provides on each second wall and is selectively attached to the other end of the feeding arm for rotating the second antenna and for feeding to the second antenna.
