A preparation method of a three-dimensional needling carbon/carborundum composite material bolt adopts a three-dimensional needling fiber prefabrication body to prepare the composite material bolt. Pyrolytic carbon is deposited on the prefabrication body, carborundum substrates are deposited through chemical vapor infiltration (CVI), and a bolt bar blank and a bolt cap blank are obtained. The carborundum substrates of the bolt bar blank and the bolt cap blank which are obtained through machining are deposited through the CVI, a carborundum anti-oxidation coating is deposited through the CVI, and a three-dimensional needling C/SiC composite material bolt end product with the shear strength being 80-100MP is obtained. Compared with the prior art, the preparation method has the advantages that the number of times for getting into a furnace is reduced by 6-10, the densifying period is shorter, and the production cost is reduced. By means of a test of a CK6180-3000 numerically controlled lathe, the preparation method is small in diamond grinding wheel abrasion, hour norm for machining 30 bolt threads is reduced by about 10 hours, and as the abrasion of a grinding wheel is less, the working accuracy is improved, and industrialized batch production is achieved.

A quilt manufacturing facility having a plurality of quilting machines is provided with an automated scheduling system which automatically generates and distributes schedules for the making of quilted products listed in input customer orders. The generated schedules are distributed in the form of computer files downloaded to the controllers of the machines. The generation of schedules is carried out by a programmed central scheduling computer which considers stored data identifying each of the machines and their capabilities, the materials available for production of the products and the product specifications, and determines the machine setting and material requirements for each product on the customer order list as well as the required completion times for each of the ordered products. Schedules for each machine are generated so as to schedule each product with other products having similar machine setting or material requirements in a manner that is consistent with the required completion or delivery times for each product. The scheduling optimizes the use of the quilting machines and operator time by reducing the number of machine setups and material changes.

Provided are a bearing device for a wheel, in which circumferential play is reduced, which provides excellent workability in connection between a hub ring and an outer joint member of a constant velocity universal joint, in which fitting between the hub ring and the outer joint member of the constant velocity universal joint is stable, and which has excellent strength, and an axle module using the bearing device. An axially extending projection is formed on either of the outer diameter surface of a shaft section of the outer joint member and the inner diameter surface of a hole of the hub ring. The projection is press-fitted to the other in the axial direction to form a recess in the other by the press-fitting. By this, a recess/projection fit structure is formed, in which the entire regions of those portions of the projection and the recess at which they are fitted to each other are in intimate contact with each other. The hardness of at least that portion of the projection at which the press-fit starts is higher than that of a portion where the recess is formed. The difference in hardness in HRC is 20 or more.
