    Abstract: A fixing apparatus is provided with a clip body. The clip body includes a body leg. A body engagement hook is formed at the body leg. A groove having a groove bottom surface is formed at the body engagement hook. The groove bottom surface extends from an outside surface to an inside surface of the body engagement hook at a central portion in a width direction of the body engagement hook. A portion of the groove bottom surface including a center axis line-side end is open toward the body head through a lock pin inserting hole. A fixing apparatus removing structure includes the fixing apparatus and a tool. A CSA fixing apparatus includes the fixing apparatus and a CSA. At a time of removing the fixing apparatus, the body engagement hook is displaced inward using the tool. Then, by pulling the tool, the clip body is removed from a body.

  • Publication number: 20150000470
    Abstract: There is proposed a method for preliminary treatment of molten iron wherein heat source for dissolving scrap is ensured sufficiently to improve iron yield while decreasing phosphorus concentration efficiently by suppressing the amount of flux solvent used in the process of desiliconization, dephosphorization and decarburization. In the method for preliminary treatment of molten iron by conducting desiliconization and dephosphorization of molten iron with a converter type container, molten iron is first charged into the converter type container to conduct desiliconization and then intermediate slag removal is conducted, and subsequently a lime-based flux solvent is added to the container while blowing oxygen to conduct dephosphorization of the molten iron, and thereafter newly untreated molten iron is charged into the container to conduct desiliconization, and subsequently the above treatments are repeatedly conducted with the same container.

  • Patent number: 8876151
    Abstract: A garnish mounting apparatus includes a rack formed at a back surface of the garnish and a tether clip for mounting the garnish to the body member at the rack. A slit is formed at the rack, and the tether of the clip extends through the slit. The tether and the slit-defining edge of the rack are movable relative to each other in a longitudinal direction of the slit and can be brought into engagement with each other in a direction perpendicular to the longitudinal direction of the slit. The clip has an engagement span for suppressing a rotational play of the garnish about a longitudinal axis of the garnish between a slit-penetrating portion of the tether and a contact portion of the clip with a bottom wall of the rack. A contact seat plane of the clip with the body member has a width for suppressing rotational play.

  • Patent number: 8752446
    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: 20140116166
    Abstract: A linear device is provided which can greatly reduce an amount of leakage of fine particles that are produced between a rolling element raceway and rolling elements to the outside of the device and which is therefore suitable for a semiconductor production apparatus or liquid crystal display panel production apparatus or other clean environment. In a linear device, each of a pair of seal members is formed to a shape which has a clearance of 0.025 to 0.15 mm in range with respect to a raceway member when cut along a direction perpendicular to the axial direction of the raceway member in a state attached to a moving member. Grease with a worked penetration of 175 to 250 is coated between the rolling element raceway and the rolling elements.

  • Patent number: 8696018
    Abstract: A fixing clip includes a clip body and a lock pin. The lock pin is temporarily held by the clip body at a temporary holding position and is securely held by the clip body at a secure holding position. When the lock pin is positioned at the temporary holding position, an entirety of the lock pin is located within the clip body. The clip body includes a rectangular body head, a body leg and a lock pin inserting hole. The body head includes side walls extending in a longitudinal direction of the rectangular body head on opposite sides of the lock pin inserting hole. Thus, when the lock pin is positioned at the temporary holding position, the lock pin is suppressed from being erroneously inserted to the secure holding position.

  • Patent number: 8662529
    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.

  • Patent number: 8567817
    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.

  • Patent number: 8419060
    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.
