    摘要： In a frequency converter, a phase-locked loop generates a local-oscillation signal having a low frequency, of a plurality of local-oscillation signals having different frequencies, based on an intermediate frequency beacon signal that results from mixing a predetermined beacon signal with the local-oscillation frequency signal. Even if the phase-locked loop is used to generate the low frequency local-oscillation signal only, a frequency offset and a phase noise taking place in remaining high frequency local-oscillation signals are compensated for or canceled out. The frequency converter thus results in a high frequency accuracy. This arrangement reduces the number of bulky, costly and power-consuming phase-locked oscillators, typically used in the quasi millimeter band or the millimeter band. A simplified, compact frequency converter is thus provided, reducing both installation and operating costs.

    摘要： Existing modems of time division duplex (TDD) type can be utilized without modification to perform a high speed wireless communication with stable communication quality in other frequency bands such as quasi-millimeter to millimeter wave bands. There are included a circulator (11) connected to TDD modems (1, 2) and receives signals transmitted thereby to output those signals from a first connection terminal (p1) and outputs signals received at a second connection terminal (p2) to the TDD modems (1, 2), and a frequency converter (2a) that raise the frequency of the signals from the circulator (11) by a predetermined frequency width and lowers the frequency of signals from a receive antenna (32) by a predetermined frequency width. It may be arranged that the frequency conversion width be made different between the uplink and downlink and that a filter, which blocks the transmitting wireless frequency and passes the receiving wireless frequency, is provided between the receive antenna (32) and a frequency converter (22a).

    摘要： It is an object of the present invention to reduce the penetration of a fuel spray directed toward a certain area in a cylinder, thereby reducing oil dilution that increases sliding resistance in the engine, reducing fuel adhesion or the like onto the cylinder liner, and also reducing the adverse effect of a fuel spray having an increased penetration.A fuel injection valve that has a plurality of injection holes and injects fuel into a cylinder 3 of an internal combustion engine includes: injection holes a2 and a6 having a larger diameter for injecting fuel toward a ring-shaped space T1 including areas A2 and A6 of strong tumble flow T formed in the cylinder; and injection holes a1, a4, a3 and a5 having a smaller diameter for injecting fuel toward a space including areas A1, A4, A3 and A5 of weak tumble flow formed in the cylinder 3. A fuel spray from an injection hole having the larger diameter has a penetration force to the tumble flow larger than the penetration force of a fuel spray from an injection hole having the smaller diameter.
