A passive radar device includes: a pulse-by-pulse range compression unit executing cross-correlation processing between received signals of a direct wave and scattered wave on each of pulses divided by a direct-wave reception unit and a scattered-wave reception unit, and calculating a pulse-by-pulse range profile; a block-by-block Doppler processing unit calculating a first Doppler frequency spectrum by executing pulse-direction Fourier transform in block units each grouping plural pulses; a Doppler frequency cell-associated range migration compensation unit compensating a range-direction movement amount with respect to the first Doppler frequency spectrum on a Doppler-frequency-cell-by-Doppler-frequency-cell basis and on a block-by-block basis; and a block-direction Doppler processing unit calculating a second Doppler frequency spectrum by executing block-direction Fourier transform on an output from the Doppler frequency cell-associated range migration compensation unit.

摘要:
A saddle-type vehicle has an engine compartment protected from mud and water splash by wheel well shields and a centrally located underbody splash guard member, arranged to substantially block mud and water from splashing back toward an engine during operation of the vehicle. These splash guards are also configured to ensure a space for maintenance. The vehicle includes inner wheel well shields located respectively laterally inside of the front wheels, and an underbody splash guard member including first and second guard portions. The first guard portion provided on the underbody splash guard member is located laterally inside of the wheel well shields, and the second guard portion is located laterally inside of the first guard portion for covering a front portion of the engine.
摘要:
A beach cleaner having a grate-like frame is formed with multiple longitudinal members. Each of the longitudinal members is provided with a plurality of sand pins projecting downward therefrom, and the frame is provided at its front end with the tow portion. The beach cleaner can be towed by a towing vehicle to generate on a sand area, while the sand pins scrape and collect waste scattered on the sand. The sand pins are detachably attached to the longitudinal members. The beach cleaner also includes a weight mount member, enabling the amount of burying the sand pins in a sand area to be optimized to enhance waste collection performance.
摘要:
After a liquid chemical treatment is finished, in parallel with a washing away treatment and/or a drying treatment, by spraying from a nozzle for a cleaning liquid supplied by a cleaning line to an outer surface of a nozzle for a liquid chemical, crystals and the like of components of the liquid chemical adhered on the outer surface of the nozzle are removed. In the cleaning treatment, a spraying time of the cleaning liquid is five seconds to ten seconds. In addition, the components of the cleaning liquid is not specifically limited, however, since ammonium phosphate tends to be solved in purified water, if a liquid chemical containing ammonium phosphate is used, it is preferable to use purified water as the cleaning liquid. Depending on the components and the like of the liquid chemical, a solution that can solve the crystals and the like may be used in stead.
摘要:
To make it easier to collect litter which is captured and deposited in a mesh member of a beach cleaner which scrapes up the litter along with sand and captures and deposits the churned up litter and sand in the mesh member. In a second beach cleaner which captures and deposits in a mesh member litter scattered around in the sand by churning up the litter along with sand while traveling by being towed by a towing vehicle, the mesh member has an encircling member open on at least one side and is attached to the frame such that the mesh member is pivotable with respect to the frame.

摘要:
A manufacturing method of an electronic device, includes the steps of: implanting P (phosphorous) ions into a substrate semiconductor region made of Si or SiGe by using a resist as a mask; ashing the resist while it is heated in a vacuum environment; and taking out the substrate, the substrate being ashing processed so that a temperature of the substrate is equal to or less than 130° C.
摘要:
To decrease adhesion of dirt to a radiator, miniaturize the radiator in front of an engine and improve engine cooling performance by efficiently applying cooling air to the engine. An oil cooler includes a first oil cooler and a second oil cooler. The first oil cooler is disposed in front of an engine. The second oil cooler is disposed in a front cover at a position higher than an upper edge of a front wheel. The first oil cooler is disposed immediately in front of a cooling fan. The first oil cooler is disposed so as to close an air intake guide of the cooling fan less than 50%. The first oil cooler and the second oil cooler are serially connected along an oil line. A heat radiation area of the second oil cooler is larger than that of the first oil cooler.
