摘要:
A wiring board includes a conductor plate including a wiring portion and an electrode portion connected to a power conversion semiconductor element, a liquid-cooling pipe mounted near the conductor plate and causing a cooling liquid to be supplied therethrough, and an insulating resin material arranged at least between the conductor plate and the liquid-cooling pipe.
摘要:
This power converter includes a power-conversion semiconductor element, an electrode conductor having a substantially flat upper end surface, and a sealant. The sealant allows the substantially flat upper end surface of the electrode conductor to be exposed at an upper surface of the sealant, and provides electrical connection with an external device at the upper end surface of the exposed electrode conductor.

摘要:
An air filter for a combustion engine for off-load motorcycles is made from a porous foam material. The air filter has contiguous side surface forming a cavity with at least two openings where the side surface contains at least one filter layer, a bottom surface closing at least one of the two openings where the bottom surface contains at least one filter layer, where the side surface has more air resistant than the bottom surface. The side surface has more air resistant than said bottom surface by arranging any combination of thickness of the surfaces, number of layers, and porosity ratio of the layers.
摘要:
A pneumatic tire includes a carcass having a first portion in which a distance between ply cords of a carcass body section and a carcass folded section gradually decreases from a position of a bead core toward outside in a radial direction of the tire, a second portion in which the distance between the ply cords gradually increases from the first portion toward outside in the radial direction of the tire, and a third portion in which the distance between the ply cords gradually decreases from the second portion toward outside in the radial direction of the tire. A notched portion is provided on a widthwise outer skin rubber of the carcass folded section of the second portion by notching the widthwise outer skin rubber inwardly in the width direction of the tire.
摘要:
A pneumatic tire having a pair of bead portions; bead cores each having a polygonal cross section; a radial carcass having respective ends wound around the corresponding bead cores from the inner to outer side; one layer of wire chafer disposed outwardly of the radial carcass relative to the bead core; and a rubber chafer in a contact area between the bead portion and a prescribed rim, wherein, in a cross section of the tire assembled with the prescribed rim, the angle between the bottom side of the bead core and a bead seat of the prescribed rim is in the range of 0±2°, and a portion, on the tire outer surface side, of an outermost layer filament of steel cords constituting the wire chafer extends at an angle in the range of 90±5° relative to the extending direction of ply cords of the radial carcass.
摘要:
An ultrasonic therapeutic apparatus according to the present invention being provided with: an ultrasonic probe (102) provided with a group of ultrasonic transducers for diagnosis use and a group of ultrasonic transducers for therapeutic use of which at least apart of ultrasonic beam irradiation surfaces are arranged so as to overlap each other, a tomographic image producing means (8) that produces a tomographic image containing a diseased portion of a subject from reflection echoes received by the group of ultrasonic transducers for diagnosis use, a display means (10) that displays the tomographic image containing the diseased portion of the subject produced by the tomographic image producing means (8), a setting means (103) that sets an irradiation path of the therapeutic ultrasonic waves on the tomographic image containing the diseased portion of the subject displayed by the display means (10) and a control means (104) that produces irradiation path information corresponding to the irradiation path of the therapeutic ultrasonic waves set by the setting means (103) and causes to display the produced irradiation path information on the display means (10) while correlating with the tomographic image containing the diseased portion of the subject.
