  • Publication number: 20120240706
    Abstract: A ball return channel of a ball screw is formed within a nut and a ring-shaped non-contact seal is arranged at the axial both ends of the nut. A suction hole radially penetrating the nut is formed within the range of a raceway (a rolling channel formed by a spiral groove of the nut and a spiral groove of the screw shaft). This guarantees not to emit dust produced inside the nut, and attains dust reduction effect higher than that of the conventional ball screw.

  • Publication number: 20120144944
    Abstract: A ball screw apparatus is provided which is less likely to increase dynamic friction torque even when a nut is contracted by cooling, and in which cooling effect is made as high as possible and which does not invite excessive machining efficiency droop and increase in pressure loss. The ball screw apparatus includes a screw shaft, a nut screwed with the screw shaft via a plurality of balls, and a cooling section cooling the nut. The plurality of balls to which preload is applied in a two-point contact state, with a preload direction as a tensile direction, are disposed between a screw groove of the screw shaft and a screw groove of the nut. Or, a ratio of the axial length L of the through hole axially formed in the nut and the diameter D of the through hole axially formed in the nut is given by an equation “10?L/D?60”.

  • Publication number: 20120056410
    Abstract: A side airbag having a high pressure chamber and a low pressure chamber divided by a sewn portion, a diffuser that distributes gas for inflation to the high pressure chamber and the low pressure chamber, and a check valve that regulates flowing of gas from a high pressure chamber side to a low pressure chamber side. A partitioning wall, that divides a lower chamber (high pressure chamber) and an upper chamber (low pressure chamber) within a side airbag, is structured by a portion of a lower base cloth (high pressure chamber base cloth) that structures the lower chamber or a portion of an upper base cloth (low pressure chamber base cloth) that structures the upper chamber. A check valve, that permits flowing of gas, jetted-out from a gas jetting-out portion of an inflator, from the upper chamber to the lower chamber and that regulates flowing of gas in an opposite direction, is provided integrally with the partitioning wall.

  • Publication number: 20120043741
    Abstract: A side airbag has a high-pressure chamber and a low-pressure chamber with a pressure lower than the pressure in the high-pressure chamber. An inflator is provided in the low-pressure chamber with a gas discharge section facing the high-pressure chamber. In a side collision, gas from the inflator is supplied mainly toward the high-pressure chamber and is supplied also to the low-pressure chamber. The high-pressure chamber and the low-pressure chamber are partitioned by a partition wall. A check valve mounted to the partition wall is opened by the pressure gas supplied from the inflator, which is provided in the low-pressure chamber, toward the high-pressure chamber, and thus the cheek valve permits the gas to flow from the low-pressure chamber to the high-pressure chamber. When the inflator completes the discharge of the gas, the check valve restricts such flow of the gas from the high-pressure chamber to the low-pressure chamber.

  • Publication number: 20110285119
    Abstract: In a side airbag system (10), a tether portion (22), which serves as a partition between an upper bag portion (16) and a lower bag portion (18), is formed of upper regions (34U) of a piece of lower base fabric (34), and is formed by sewing the upper regions (34U) of the lower base fabric (34), folded toward a vehicle front side along a fold axis, together. In addition, a tube (24) that distributes inflation gas between the upper bag portion (16) and the lower bag portion (18) extends through the tether portion (22) to the lower bag portion (18) and to the upper bag portion (16). The tube (24) is formed into a cylindrical shape in such a manner that a piece of tube base fabric (36) is sewed to the upper regions (34U) of the lower base fabric (34) and folded toward a vehicle front side along the fold axis and then front ends (36F) of the folded tube base fabric are sewed together in a tube longitudinal direction.

  • Patent number: 7161872
    Abstract: A fish depth monitor is a device that can display first water depth data that indicates the location of terminal tackle that is engaged on fishing line reeled out from a spool, and second water depth data that indicates the location of the bottom of a fishing location transmitted from a fish finder, and includes a case, first and second reception portions, a display unit, and a control unit. The first and second reception portions receive the first water depth data from an electric driven reel and the second water depth data from the fish finder. The control unit graphically displays the received first and second water depth data in positions that correspond to the water depth on the display unit. It is possible to intuitively determine the positional relationship between the location of the terminal tackle and the location of the bottom.

  • Patent number: 4833529
    Abstract: A color separated image processing means includes a plurality of line sensors each receiving a different color-separated light image. The respective light images are converted into corresponding image signals which are respectively normalized with respect to respective reference signals. And, the normalized image signals are compared one from another by a color identifying circuit which supplies as its output a status signal indicating the presence or absence of an intended color for a pixel under examination. The status signal and the normalized image signals are supplied to a color separating circuit which supplies as its output either a first color image signal, which is obtained by carrying out a predetermined calculation using the normalized image signals, or a second color image signal, which corresponds to a predetermined one of the normalized image signals, depending on the state of the status signal.
