    摘要: In a multiple propagation wave parameter measuring method, transmission waves are radiated into an outer space. The transmission waves are received as a multiple propagation wave. Arrival directions of the transmission waves are measured on the basis of reception signals. The transmission wave arriving from one direction of the measured arrival directions is defined as a desired wave, and the transmission waves arriving from remaining directions are defined as unnecessary waves. A weight with which a reception power ratio of the desired wave to the unnecessary waves becomes maximum is calculated. The reception signals are multiplied with the weight to extract the reception signal in which the unnecessary waves are suppressed. A change in delay time of the desired wave from a transmitting device to a receiving device is calculated on the basis of the reception signal in which the unnecessary waves are suppressed. A machine-readable recording medium storing a multiple propagation wave parameter measuring program is also disclosed.

    摘要: A four-stroke engine for a working machine with a rod is provided, where a tool is attached to one end of the rod in a longitudinal direction and the four-stroke engine is fixed to the other end of the rod in use. The four-stroke engine includes: an oil circulation pathway; and a gas-liquid separating chamber configured to separate oil from blowby gas. The gas-liquid separating chamber includes: an inflow part into which the blowby gas is introduced from the oil circulation pathway; oil discharge parts configured to flow the oil separated from the blowby gas back to the oil circulation pathway; and a blowby gas discharge part configured to discharge the blowby gas not containing oil mist from the gas-liquid separating chamber and supplies the blowby gas to an intake passageway to a combustion chamber.
