  • Publication number: 20140061398
    Abstract: A holding structure is provided for an option connector that is mounted at an end of a branch line of a wire harness of a vehicle. A fixing part is defined at an area of the branch line separated from the option connector by a predetermined distance. A holding part is provided on a peripheral component of the vehicle that is in a vicinity of the wire harness. The holding part is configured for releasably holding the fixing part of the branch line so that a tip area of the branch line that begins at the fixing part and includes the option connector extends out from the holding part.

  • Patent number: 8387417
    Abstract: It is an object of the present invention to uniformly disperse fibrous material such as short glass fibers so as to be distributed on a collection conveyor, without using compressed air for dispersion of the fibrous material. The present invention provides a method for collecting fibrous material, wherein the fibrous material fiberized by a spinner of a fiberizing unit is dispersed by a hollow bucket disposed just under the spinner, so as to be collected on a collection conveyor disposed below the hollow bucket, comprising: forming said hollow bucket by connecting a blasting section having an oval opening at its lower end, with a waistline section as a lower end of a hopper section having a circular shape in cross section, and deforming the inner surface of the blasting section toward said oval opening, thereby dispersing the fibrous material dropped in the hollow bucket in a width direction of the collection conveyor from the blasting section, so as to be collected on the collection conveyor.

  • Patent number: 4932438
    Abstract: In a valve provided with a fixed valve body (13) forming a passage of a fluid and a movable valve body (14) arranged relatively movably in contact with this fixed valve body (13), in order to smooth the sliding between the fixed valve body (13) and movable valve body (14) over a long period, the sliding surface part of at least either of the above mentioned fixed valve body (13) and movable valve body (14) is formed of a ceramic compound charged with a lubricant in the open pores of a sintered ceramic body having open pores of a three-dimensional network structure. Thereby, the fluid passage can be connected and disconnected always lightly and stably by the operation of an operating lever (17) and the sliding of the fixed valve body (13) and movable valve body (14) in close contact with each other can be maintained over a long period to prevent the fluid from leaking out.
